rope displacement sensor in elevator rope displacement sensor In today's society, elevator is an important means of transportation related to the safety of people’s life and property in modern buildings. It is a complete set of equipment for fixing and lifting on floors. It is composed of hoisting traction system , Guidance system, safety device and electronic control system. How to improve the operating efficiency of the elevator, reduce the energy consumption of the elevator, reduce mechanical wear, and extend the service life of the elevator are all very important research topics. So what kind of role does the rope displacement sensor play in the elevator? Today I will discuss this topic with you:
1. At present, elevator control generally adopts two methods. One is to use a microcomputer as a signal control unit to realize the automatic dispatch and collective operation functions of the elevator, and the drag control is completed by the inverter; the second control method can be used. The programming controller (PLC) replaces the microcomputer to realize signal collective control.
2. The rope displacement sensor is used to realize elevator leveling control, which can realize the intelligentization of elevator control. The elevator has a good sense of comfort, and the comfort of starting, decelerating and leveling will not change due to the change of the car load. The function of the displacement sensor in the elevator control system is the adjustment of elevator leveling control. The electronic control system is the "central nerve" of the elevator. In order to make the elevator have a higher operating efficiency, the acceleration and deceleration should have an appropriate limit and change To be stable, a well-designed electronic control system is required.
3. The function of the displacement sensor in the elevator control system is the adjustment of elevator leveling control. The electronic control system is the "central nerve" of the elevator, and its quality directly affects the elevator quality. Both passenger elevators and medical elevators pay attention to riding comfort, and comfort is related to running time. In order to ride comfortably, it is necessary to extend the acceleration and deceleration time, so that the running time will be prolonged and the elevator running efficiency will be reduced. Therefore, in order to make the elevator have a higher operating efficiency, the acceleration and deceleration should have an appropriate limit, and the change should be stable, which puts forward the following requirements for the electronic control system:
In summary, the rope displacement sensor is in the elevator. We all know that elevators must be safe and reliable, and easy to troubleshoot. Under the premise of meeting the requirements of use, the simpler the line, the better. Therefore, the selection of components should be reasonable, the electromagnetic sound should not be loud, the structural parts of the installation parts should have sufficient rigidity, and there should be anti-loose measures. Displacement sensors play a very important role in this regard, keep paying attention!
