Brief introduction of Alva Wang project

Intelligent broadcasting emergency command system is an intelligent multi-channel audio service system based on emergency command priority. Under the premise of fully meeting the technical standards of cable TV network operation, it can play up to 40 audio programs with high fidelity at the same time. The system adopts the original address coding remote control technology, which can be forced to switch or power on to an emergency state for command and broadcasting in an emergency or some needs; It can also easily alarm, notify or repeat specific programs by region. The system adopts high-tech means with low cost and high performance, which is convenient, fast and simple to operate, and can be widely used in hotels, residential quarters, commercial buildings, wholesale markets, tourist areas and other public places. At the same time, it can also provide powerful technical means for the management institutions in these places to strengthen functional management, upload and publish smoothly, strengthen information publicity and establish a rapid response mechanism. This technology has been protected by many patents at home and abroad, and it is a public information service system with independent intellectual property rights.

(2) TH micro-control spring testing machine

Position: Software Engineer

Project introduction:

TH micro-control spring tester is mainly used to automatically measure the performance of cylindrical springs such as GK three-way valve, 103/ 104 distribution valve, 120 control valve, F8 distribution valve, empty and loaded car valve, etc. The system takes a microcomputer as the main control unit and a high-precision and wide-range pressure sensor as the detection means. Based on motion control technology, accurate digital measurement and control are realized, which ensures the rapidity and accuracy of system measurement. Unique mechanical design and processing technology realize compact and beautiful mechanical structure. The system is easy to use and maintain, and it is unique among similar products in the whole railway.

(3) train passing detection safety protection device

Position: Project Manager

Project Source: Shenhua Science and Technology Innovation Project

Project number: SHGF-06-32

Project type: (technical development)

Project introduction:

CHT- 1 Train through detection safety protection device can automatically give an alarm when the abnormal wind pressure leakage of the train supervisor is lower than the specified threshold, prompting the locomotive crew to operate; Through normal decompression operation, the device can automatically and correctly judge and display the blocked state of the whole train door; When the corner cock of the vehicle is accidentally closed, the crew can operate the rear of the train to implement exhaust braking. Therefore, the locomotive crew can timely and accurately grasp the wind pressure at the rear of the train, find the separation of the train, avoid leaving the car in the interval, and judge the closed position of the train corner cock; Be able to record train tail data and crew operation in CHT- 1 record plug-in; As a symbol of the train's tail day and night. Thereby preventing train accidents, improving driving safety and ensuring smooth railway transportation.

This device is the first set of train safety operation device in China, which realizes the detection of diagonal door blocking state and train tail exhaust.
