Specific implementation mode

The utility model is described in further detail below in conjunction with the accompanying drawings：

For the utility model in the communication link (as shown in Figure 1) of original sensor receiving terminal and GCU, parallel connection is added one Data acquisition module based on serial communication, the data transmit-receive between GCU and sensor, which interacts, to be acquired by this module, such as Fig. 2 Shown, J7 is the interface in GCU physical boards, and a gate passage increases a data acquisition module, which can acquire In this channel all to penetrating, the state of diffusing reflection sensor.

The data acquisition module includes GCU signal acquisition circuits, collecting sensor signal circuit；The GCU signals are adopted Collector is connect with GCU, receives the instruction that GCU is sent to gate cell, and send it to communication module；The sensor signal Acquisition Circuit and the receiving terminal of each sensor in gate passage are separately connected, and acquire the status data of each sensor, and Send it to communication module；The communication module by internet by GCU send to gate cell instruct, each sensor Status data is sent to remote monitoring end.
