Principle of remote monitoring implementation:

1. We set up a monitoring center in TGE headquarters in Beijing to monitor the control system of TGE revolving door being used all over the country through signal receiving and sending devices.

2. The control system adopts Siemens PLC and frequency converter to centralized control, a total of 64 terminals, high sensitivity, flexibility, through the output signal, to ensure that the rotary door

movement and stop.

3.  If the monitored revolving door fails, it will be sent to the host computer of Beijing monitoring center through the data signal receiving and sending device using GPRS(which is realized by mobile 

phone card) for direct debugging0
