目前上海地铁进出口处多使用三杆式闸机。三杆式闸机并不像门式闸机一样带有报警系统,不能有效地防止乘客逃票。通过采用MSP430F149芯片作为中央微处理器,对外围的红外线对射传感器模块、RFID读写卡模块、电源模块、声光提醒装置模块等等进行控制,所组成的红外线传感器监测报警装置可合理的安装在三杆式闸机上达到报警效果,同时减少重新购置新闸机的成本,原有三杆式闸机不用替换,节约大量的资源。
At present, Shanghai Subway Import and Export Department to use more three-bar gate. Three-lever gate does not have the same alarm system as the gate-type gate, can not effectively prevent passengers fare evasion. By using the MSP430F149 chip as a central microprocessor, infrared infrared ray sensor module, RFID card reader module, power supply module, sound and light reminder device module and so on are controlled. The infrared sensor monitoring and alarming device composed by the MSP430F149 chip can be installed rationally Achieve alarm effect on the three-bar gate and reduce the cost of re-purchasing the new gate. The original three-bar gate without replacement, saving a lot of resources.
