Detailed description of induction door maintenance; After reading it, I have a deeper understanding of the induction door.

The "induction" of induction door is a way to open the door. Usually, the automatic door we often see at the door of hotels, shops and units is the induction door. The service life of induction doors is largely influenced by daily correct use, reasonable maintenance and timely maintenance. Today, Bian Xiao introduced the maintenance knowledge and working principle of the induction door.

I. Maintenance of Induction Door

The power supply must be provided with special lines, and it is forbidden to mix with other electrical appliances.

The product can be used only after it is firmly installed and debugged.

The control box must be installed in a dry and ventilated place, and it is forbidden to get close to high-power radio equipment, so as not to affect the normal work. When using the control button, don't use too much force or too much force to avoid damage.

When the door is running, people and vehicles are forbidden to stay on the guide rail. Operators should always pay attention to the operation of the door to avoid accidents.

Track should be cleaned frequently to avoid debris accumulation affecting operation.

Lubricate the driver at least once a year, and often lubricate the chain of the induction door, and check the wear and tear of all parts. Parts with serious wear should be repaired or replaced in time.

When pushing and pulling the induction door, open it gently and close it slowly. It is forbidden to push and pull hard to cause damage.

When the product breaks down, please inform the professional maintenance personnel to carry out maintenance in time. Non-professionals are not allowed to open it without authorization.

The above is an introduction to the maintenance knowledge of induction doors, so you can know about it. Proper maintenance of induction door can prolong its service life.

Second, how to correctly select the induction door

Accurately speaking, the induction door is a system that automatically obtains the door opening mode when people approach the door, then opens the door through the driving system, and automatically closes the door when people leave the door, and the whole process can be controlled. How to choose and buy the induction door correctly? The following small series introduces the main points of choosing the induction door.

Sensor: in high-end hotels and office buildings, you can choose high-sensitivity sensors; Choose sensors in narrow areas where people often pass, such as banks and shops on sidewalks.

Safety auxiliary device: in high-end hotels and other places, it is necessary to put an end to the pinch incident of induction doors, and you can choose to install anti-pinch infrared sensors.

Installation of access control system and electric lock: the installation of induction door in self-service bank can increase the installation of access control system and electric lock in self-service bank and realize the control of access.

Equipped with standby power supply: in order to ensure that the induction door can work normally in the case of power failure, it can be equipped with standby power supply.

The above is the introduction of the main points of buying the induction door, so you can know about it. The quality of induction door fittings is directly related to the life of the door.

Third, the automatic induction door principle

Automatic induction door's door opening signal mainly includes microwave radar and infrared sensor. Microwave radar responds to the displacement of objects, so it has a fast response speed and is suitable for places where people with normal walking speed pass by. Its characteristic is that once people close to the door don't want to go out and don't move, the radar will no longer respond, and the automatic door will close, which has a certain protective effect on the door machine. Infrared sensors react to the presence of objects. No matter whether people move or not, as long as they are within the scanning range of the sensor, it will respond and send out contact signals. The disadvantage is that the infrared sensor has a slow response speed and is suitable for places where people move slowly. In addition, if the automatic door receives the contact signal for too long, the controller will think that the signal is input into the system and there is an obstacle. Moreover, if the automatic induction door is kept on for too long, it will also cause damage to electrical components. Because microwave radar and infrared sensors don't know whether people close to automatic doors really want to enter the door, they prefer to use key switches in some occasions.

The key switch can be a touch button, which is more convenient. The toggle switch is durable, especially it can be operated by elbow. Avoid hand contact. There is also a kind of foot switch, which has the same function, but has higher waterproof requirements, and the foot switch is prone to failure because of its great strength. There is also a handle with a contact switch, which will provide a contact signal to the portal crane when the handle is pushed into position (or pulled in the opposite direction).

For the access control system and automatic doors in non-public areas, if the performance and quality requirements of automatic doors are the highest, they are in large-scale public areas with extremely high frequency of use, then the functional requirements of automatic doors are to select people's non-public areas. Access control system is the identification of access rights. After the identification or detection of access authorization passes, the door opening signal is provided to the control system of the automatic door. The automatic door must be locked before the door opening signal is provided. The access control system includes the simplest key switch, coded lock and magnetic card lock. (attendance statistics system). Until the complex weight identification system, fingerprint identification system and so on. However, no matter how complex the system is, it will eventually provide the contact signal for the automatic door to open. It is very important to shield the signal circuit, which can avoid opening the door by mistake due to the interference of irrelevant signals.

The requirement of automatic door is the coordination of unlocking action and opening action. There are three kinds of electronic locks for automatic sliding doors: electromagnetic locks for locking seat belts, electric locks for locking car body hooks, and lock motors. The latter is used for heavy automatic sliding doors. Electronic locks of automatic sliding doors include electromagnetic door stopper, electronic latch and electronic door opener. The direction of the force of electronic door opening does not affect the opening action of the door, and misoperation is not easy to occur. There is also a mechanical lock with a contact switch, which combines the lock and the switch into one. When the lock is not in the unlocked state, the contacts can't be touched, and it is impossible to misoperate.

Centralized control. The concept of centralized control includes two meanings: centralized monitoring of the running state of automatic doors and centralized operation of multiple automatic doors. The position signal output circuit can realize centralized monitoring of automatic door switch state, and contact switch can be used. When the door reaches a certain position (such as the open position), the switch is triggered to give a contact signal. You can also use an induction signal generator. When the sensor detects that the door is in a certain position, it will send out a signal. The status of automatic doors can be displayed by setting corresponding indicator lights in the central control room, while centralized operation usually refers to opening or locking multiple doors at the same time, depending on whether there are corresponding terminals on the automatic door controller.

Introduction of induction door:

Induction door: addition induction door refers to translation induction door and plane induction door, and "induction" refers to a door opening method in automatic doors.

Induction doors can be divided into framed doors and frameless doors according to the manufacturing process.

Induction door mainly means that the control system of door switch is realized by induction, which can be divided into infrared induction door, microwave induction door, swipe card induction door, touch induction door and so on according to different induction methods.

The door body is generally made of tempered glass, stainless steel plate, color steel plate or some special materials.

The use of induction doors can save air conditioning energy, reduce noise, prevent wind and dust, and make our entrances and exits look solemn and high-grade. However, if the induction door is used for a long time, it will also fail and generally needs maintenance. The above is the principle and maintenance method of the induction door introduced by Bian Xiao. You can learn about it.
