Abstract
The utility model is an alarm device. A section infrared relay group is arranged between a head end emitter and a terminal receiver. Each group beginning terminal transponder comprises an infrared receiver module, a decoding integrated circuit and a coding integrated circuit and an infrared transmitting tube. Each group other infrared transponder is composed of a receiver module and a transmitter module; the receiver module in the terminal infrared receiver is connected with the decoding integrated circuit with each output end of interlock characteristic, and the output ends have thyristor switches respectively, and the loop is connected with an acoustic-optic alarm circuit. When the optical path in the device is unobstructed, each relay group can receive and retransmit the optical pulse coded in the head end infrared emitter. When the optical pulse in certain section range is hindered or is interrupted temporarily, the head end infrared transponder in latter section relay group can immediately export an optical pulse train different from the prior coding set, and terminal infrared receiver expresses the indicator light in certain section is open and meanwhile an alarm sound can be sent out. The utility model has the outstanding advantages that the alarm device can inform the concrete section position entered in the alert area in time.
