Tyan door sensors in the sensor to scan range Tai'an door sensors automatic door sensors for the basic composition of substantially the same composition with the above, plus the open signal, it can be configured into a simple system of automatic doors. Automatic door sensors of the system configuration is defined according to the requirements and equipped with automatic door controller connected to the auxiliary control peripheral devices, such as open source, access control systems, safety devices, centralized control. Must be based on use of the building features. Through the composition of staff, building automation system requirements with a reasonable auxiliary control devices. Open signal: automatic door opening signal is contact signal, microwave radar and infrared sensors are two common sources: Microwave radar displacement response of the object, and thus fast response for a normal person walking speed through the place It is characterized by a once near the door staff do not want to go out while stationary, the radar will no longer react, automatic doors will be closed, door machine has a protective effect. Infrared sensors react to the object exists, whether or not the movement of persons, as long as in the sensor scanning range, it will be the reaction that came contact signal. Drawback is slower reaction infrared sensor, suitable for slow-moving people out of the place. In addition, if the automatic door contact signal received long time, the controller will think the signal input system obstacles. And if the automatic sliding door remains open for too long, will produce damage to the electrical components. Because microwave radar and infrared sensors close automatic doors do not understand people who really want to the door, so some places are more willing to use the key switch. Key switch can be a contact-type buttons is more convenient to contact the so-called toggle switch. Elbow touch switch is very durable, in particular, it can be used to operate the elbow. Avoid hand contact. There foot switch, the same function, but the water is higher, and the pedal force is large, easy to make the foot switch failure. There is also a contact switch with the handle when handle is pushed (or pulled in the opposite direction) in place, to provide door contact signal. Now building automation sometimes make special requests, such as the use of a sub-line control of the phone to open the door. To meet this requirement, as long as the signal is passive contact signal can be. In some cases, it will move the remote antenna requirements.
