| Abstract: | Giving any monitored area an address, the wireless transmitter sends wireless warning signal when the area has problem . At the same time the receiver can automatically recognize the address of monitored area and display the coded number of the area , then give alarming signal . In the paper the principle and the configuration of the wireless alarming system is introduced, meanwhile the anti-interference measurement and the way to low the error-alarming rate are mentioned . |
