chrispeng [ad_1]
1. System significance
1) Long-distance sensing enables vehicles to enter and exit the fire brigade park quickly without stopping
2) Real-time monitoring of vehicle entry and exit status, and provide real-time warning information notifications to ensure the safe entry and exit of fire-fighting vehicles and fire-fighting vehicle statistics
3) Automatic identification and automatic release of fire-fighting vehicles, eliminating manual intervention and avoiding human operation loopholes
4) Set a safe time zone, and start an alarm when the fire-fighting vehicle goes out in the background during an unspecified time zone to ensure the safety of the fire-fighting vehicle
2. System architecture and program description
The fire brigade vehicle access management system is a set of management system developed by Shanghai Renwei Electronic Technology Co., Ltd. according to the actual situation and demand characteristics of the fire brigade management. It adopts dual-frequency semi-active RFID technology, from dispatching vehicles to vehicle entry and exit monitoring and The vehicle maintenance system is completed, which has the characteristics of advanced, reliable, safe, convenient and fast, which makes the various tasks of vehicle management more organized, and fundamentally effectively solves the problem of fire vehicle management, thereby improving the level of fire vehicle management. .

2.1 Program description
The activator is installed in the guard room or the periphery, and two 125K coils are led out; they are the activation antenna No. 1 and the activation antenna No. 2, when it has dual frequencyelectronic labelWhen the vehicle enters the unit’s gate, when it is within the range of 1-3.5 meters from the No. 1 activation antenna, the low-frequency activator will emit electromagnetic waves and be received by the dual-frequency electronic tag. The low-frequency electronic tag receives the energy carried by the electromagnetic wave and transmits 2.4G The active electronic tag is activated. After the active electronic tag is activated, the ID information of the electronic tag itself and the ID of the activator are sent to the reader at a certain rate.ReaderReceive the radio frequency signal from the dual-frequency electronic tag and the IP of the activator and transmit it to the background through the 485 or TCP/IP interface; as the vehicle gradually enters the inside of the gate, the electromagnetic wave energy carried by the activator gradually weakens until it can no longer activate the personnel Dual-frequency electronic tag, and the B activator starts to activate the vehicle electronic tag. After the electronic tag is activated, the ID information of the electronic tag and the IP of the activator are sent to the reader at a certain rate, and the reader receives the dual-frequency electronic tag. The radio frequency signal and the IP of the activator are transmitted to the background through the 485 or TCP/IP interface, and the background judges according to the order of reading by the low-frequency activator and the ID numbers of different activator antennas;
