Integration of two informatizations to create a new Liaoyang

Liaoyang is the earliest city established in Northeast China, with a history of more than 2,400 years. It has a population of 1.834 million and a total area of ??4,743 square kilometers. It is one of the 14 municipalities directly under the Central Government in Liaoning Province, with 1 county, 1 county-level city, and 5 districts under its jurisdiction.

As soon as you get out of Shenyang Xiantao International Airport, take the Shenyang-Dalian Expressway and drive 60 kilometers to Liaoyang City. This is also a place that Liaoyang people are proud of. The entire Liaoning Province is within a 3-hour transportation, economic and living circle. Shenyang, Anshan, Benxi and Fushun are all within one hour's economic circle from Liaoyang. Fuxin, Dandong, Panjin, Yingkou and Tieling are within the two-hour economic circle. The three-hour economic circle can not only reach Chaoyang and Huludao in western Liaoning, but also cover cities in Inner Mongolia and Jilin in the north.

According to Zhang Biyong, member of the Standing Committee of the Liaoyang Municipal Committee of the Communist Party of China and deputy mayor of the Liaoyang Municipal People's Government, Liaoyang is a city with an active private economy and a strong industrial foundation. It has initially formed chemical industry, chemical fiber plastics, metallurgy and nonferrous metals There are five pillar industries: processing, equipment manufacturing and parts supporting, mining and building materials industry, and agricultural and sideline products processing. The trend of integrating industrialization and informatization is also reflected in Liaoyang's chemical industry, mining and building materials industry, which has considerable advantages.

Digital Mining

Liaoyang Gongchangling Iron Mine is affiliated to Anshan Iron and Steel Group Corporation and is an important main source of raw materials for Anshan Iron and Steel Group. . Since 2006, three-dimensional virtual open-pit mining system, three-dimensional virtual underground mining system, equipment intelligent inspection system, GPS and other systems have been deployed and implemented in Gongchangling Mining Company (hereinafter referred to as "Gong Mine"), and Gong Mine has begun to fully Functions such as production planning, personnel safety, environmental monitoring and management decision-making are realized through a unified information platform.

The relevant person in charge said that the problem in the ore mining process is how to ensure the safety of mining personnel? Is the operation of the equipment stable? How to transport ore resources out of mines reasonably and safely? We launch various informatization projects to solve these problems.

The mining system adopted by Gongchangling Mine realizes true three-dimensional ore body modeling. The ore bodies in the system show different colors, and each color represents a different grade of ore. If you plan to mine a certain part of the mining area, you only need to click the mouse to delineate the planned mining area, and data such as the number of rocks and ores, geological grade, dilution rate, ore transport distance in this part will be automatically generated. These data will help Management accurately develops production plans, such as piercing, rock production, ore production, quality, trucking turnover plans, etc.

Operators can also use "digital knife" technology to rotate and section the ore body at will, and intuitively display various geological data information in different areas and levels. By automatically collecting geological profiles and drilling data in the mining area, the system can determine the plane trajectory of the ore body, and finally utilize the spatial change patterns of the ore body to achieve true three-dimensional ore body modeling. Behind each point is a database. These data are obtained by staff through aerial photography, GPS positioning, and production point description data entry. The more comprehensive the data information collected, the closer the situation displayed by the system will be to reality. .

The staff of Gongchangling Mining Company told reporters that through actual operations, they felt that the three-dimensional virtual mining system is efficient and intelligent. As long as the corresponding dialog box is clicked, the system can According to the different needs of users, various production reports are automatically generated based on machines, teams, workshops, and entire mines, and in hours, days, months, quarters, and years. Daily, monthly, and annual plan reports for the ore production of the workshop and the entire mine, as well as daily, monthly, and annual actual production and quality analysis reports for the workshop and the entire mine, can also be quickly generated.

Production safety issues have always been an important problem plaguing China's mineral mining industry. This has a lot to do with the complex mining operating environment and poor communication between above and below the mine. Gong Mine currently has a total of 2,200 employees, including 1,800 people who work underground for a long time, and implements a three-shift working system. The geographical location of the underground operation site is very complex. It is divided into the central mining area and the northwest mining area, with up to 12 operating levels. The mining tunnels are 1,500 meters long from east to west, and the deepest is 340 meters underground. In the future, the deepest mining will reach 700 meters underground. depth. Another major feature of the construction of Gong Mine Digital Mine is the realization of safety management of employees. When the reporter and his party went to the Gongchangling Mine, it happened to be the largest mining explosion of the year in the mine. 46 tons of TNT exploded. Five minutes after the reporter withdrew from the conference room in the mining area, he felt a momentary vibration on the ground. At that time, all personnel in the mining area had been evacuated to the ground, and what helped the management department confirm that all personnel had evacuated was the personnel positioning system.

It is understood that every worker in the Gongchang Mine has a signal transmitter on his helmet. From the moment the worker enters the underground, it is reflected as a red dot in the system. Ground operators can view the location of personnel and the working status of equipment in real time on the three-dimensional solid model. Workers going down the mine and moving around in the tunnel are reflected in the movement of red dots. Ground personnel can query the worker information represented by each red dot, including name, work number, time of going down the mine, walking route, etc. Once a safety incident occurs, ground personnel can also promptly notify personnel to evacuate through their mobile phones.

Can I still make phone calls underground? On November 6, the underground iron ore mobile signal deep coverage project invested and constructed by Liaoyang Mobile in Gong Mine was successfully completed. The current GSM mobile communication signal coverage range is 157 meters above ground and 340 meters underground, which greatly facilitates the communication between ground personnel and underground personnel. connect.

In the past, each horizontal working surface only had one internal landline phone to communicate with the outside world. It would take at least two hours for us to find an underground person. Once an accident occurred, workers would run to the landline phone. It takes a long time. ?Zhou Fengfei, deputy general manager of Gongchangling Mining Company, said. ?Now, after the deep coverage of mobile signals is realized, through the push-to-talk service, the mine can conduct one-to-many calls and dispatch contacts with underground offices and miners on each floor, and real-time contact has become a reality. ?

Software promotes energy conservation

PetroChina Liaoyang Petrochemical Fiber Company (referred to as Liaoning Chemical Company) is a very large petrochemical company in my country. The chemical fiber joint enterprise is located in the southeast of Liaoyang City, covering an area of ??16 square kilometers and currently employs 30,000 people.

By adopting the team cost accounting information system developed by Liaoyang Yunhe Software Development Co., Ltd., Liaoning Chemical Company has embarked on a cost control path that uses information technology to save energy and reduce consumption.

Ren Yuexin, the current general manager of Yunhe Software, started his business from Liaohua Company. From 1989 to 2000, he was engaged in software development and maintenance in the computing room of the Design Institute of Liaohua Company. In August 2000 Liaoyang Yunhe Software Development Co., Ltd. was founded. While working at Liaohua Chemical, he discovered that teams are the direct creators of corporate benefits and direct consumers of corporate energy. However, the general management software is top-down management and does not manage the teams of grassroots production units. , informatization has not really been implemented.

So, starting in 2003, Yunhe Software began the research and development of a team cost accounting information system. Li Xiujie, deputy technical director of the No. 1 Alcohol and Ketone Workshop of the Nylon Plant of Liaoning Chemical Company, has been engaged in cost management since 2000. She has a deep understanding of the role played by the team cost accounting system. ?Before 2003, our cost accounting was manual accounting, and the personnel on duty had no way of knowing the production costs of their own shift. It was not until we started using the cost accounting information system in January 2005 that we entered the information application stage. Data entry is intuitive and convenient, data query is flexible and fast, summary tables can be automatically generated, and dynamic accounting can be performed to find cost increase and decrease points in a timely manner. ?

The system not only calculates costs, but the staff also promptly discovers equipment hazards through dynamic analysis of cost changes. On October 21, 2007, Chemical Engineering Class C conducted a cost analysis after the night shift and found that the unit consumption of the cyclohexane unit was high, while the unit consumption of the alcohol and ketone unit was very low. After inspection, it was found that the benzene consumption of the U82 equipment was normal, and the alcohol and ketone output of the U83 equipment was also normal. It seems that the problem lies in cyclohexane. After analysis and search, it was found that the aging of the valve caused material channeling between the two cyclohexane receiving and discharging tanks, and a safety hazard was discovered.

In 2008, the MES (Manufacturing Execution Management) system of Liaoning Chemical Company was launched, and Yunhe Software Company developed a data collection interface with MES to realize the automatic collection of team accounting data, making dynamic costs Accounting just got easier. Using the dynamic accounting function, the team can input operating data at different times at any time, and the completion status of each indicator can be seen at a glance. Through dynamic accounting and cost analysis, the team can promptly discover equipment production and operation problems, instrument problems, and minor changes in various active indicators to avoid accidents.

On the night shift of May 17, 2008, the U83 equipment of Liaoning Chemical Company was put into operation after alkali cleaning. During the dynamic accounting, the chemical engineering shift found that PW water was continuously consumed. Under normal circumstances, the PW water of the device was It is only consumed when parking. On-site inspection by staff found that the water inlet valve was closed. After inspection by the equipment personnel, it turned out that the valve top was broken and it was repaired in time. ?The consumption of PW water is 12 tons/hour, and the price is 10 yuan/ton. If it is discovered and processed until the day shift, at least 80 tons of precious PW water will be wasted. ?Li Xiujie said.

Building a three-dimensional digital city

Gongchangling District is the first urban district in Liaoyang to carry out the construction of a "digital city". In September 2007, the Gongchangling District Government invested 20 million yuan to start the construction of a "digital city". Jujin Technology, which undertook this project, investigated the digital city construction experience in Beijing, Shanghai, Suzhou, Yangzhou and other places, and found that previous digital cities were all two-dimensional, making it difficult to accurately describe complex three-dimensional forms and unable to achieve true digital city construction. Solid modeling, the data generated does not fit well with the actual application. Based on these circumstances, Jujin Technology has made "three-dimensional modeling" the focus of Gongchangling digital city construction.

This system, which is still under construction, includes more than 20 subsystems such as a three-dimensional geographic information system. According to the plan, after completion, it will be connected to the databases of various local government departments.

The system relies on three-dimensional modeling technology and combines GIS, RS, GPS, computer network and virtual simulation technology to reproduce the distribution status of various resources in the city, promote information sharing between different departments and levels in the city, and Through government organizations, digital means are used to process, analyze and manage the entire city.

The reporter saw that although the system is still under construction, the prototype of the future digital city has already emerged. The entire Gongchangling District is condensed into a three-dimensional geographic information system. Click on the main traffic road in Gongchangling District? Anping Township, and you can even clearly see the name of each store next to the street, such as Xiaowang Clinic ?, ?Anping Food?, etc. The staff said: "These shops are real shops on the streets of Anping Township. We obtained these real location data through aerial photography, field measurements and other means."

In this digital city, every street and every house is three-dimensionally modeled based on real data. When the mouse slides over a building, you can see the specific floor and house number where the mouse is located. If it is a commercial housing, you can see the name of the unit; if it is an individual household, you can also see the residents living here in the future. Name, ID number, etc.

Referring to the grid management model of Dongcheng District in Beijing, Gong Changling also proposed a similar idea. If a manhole cover in a certain sewer in the city is lost, the urban management can use a wireless collector to take pictures of the incident location. After logging into the urban management wireless collection system, the photos, events and other information will be transmitted to the monitoring center, which will file the information and send it to the command. center. The command center decomposes tasks to relevant departments based on the corresponding units for different events. After the relevant departments complete the processing, fill out a task feedback form and submit it to the command center.

However, the biggest difference between the grid management of Gongchangling and Beijing Dongcheng District is the three-dimensional modeling. For example, for a building, not only can it be rotated and viewed at any angle, but the building can also be cut at any angle, such as side cutting, cross cutting, vertical cutting and other operations. After cutting, you can also clearly see the internal structure of the building, such as where the stairs, fire escapes, water and electricity lines are, and what the layout of the rooms in the building is.

? Behind every point in this system is a huge database, such as the population database of the Ministry of Public Security, etc., which contains unlimited possibilities for urban management. For example, after a fire breaks out, relevant personnel can clearly understand the internal structure of the building and organize evacuation effectively. Said the person in charge of Gongchangling District Digital Domain City.

Talking about the bright prospects of digital cities, Zhang Biyong was very excited. After Gongchangling District realizes digital cities, this model will be expanded to other areas of Liaoyang, and eventually the entire Liaoyang city will be connected into a digital city. The scope of application of the large network can also be extended to the intelligent management and control of urban traffic, detection and sustainable utilization of urban resources, prevention and control of urban disasters, supervision and management of production safety, urban environmental governance and protection, construction and management of urban communications, Virtual simulation city, land and resources management and other aspects.
