Description of drawings
Fig. 1 is that the present invention continues and protects the module frame chart of test monitoring alarm device;
Fig. 2 is the continue structural representation of the infrared ray transceiving isolator of protecting test monitoring alarm device of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate specific embodiments of the invention.
As shown in Figure 1, the present invention discloses a kind of continuing and protects the embodiment of test monitoring alarm device.This device comprises: infrared ray transceiving isolator 1, and circuit connects this infrared ray transceiving isolator 1 single power supply partition apparatus 2 and display alarm device 3 of output respectively.
As shown in Figure 2, infrared ray transceiving isolator 1 adopts infrared double-core to penetrate mutually fence.Adopt battle array Tai'an guarantor's echelette equipment in the present embodiment, this infrared ray transceiving isolator 1 correlation scope is 15 meters, and meeting continues protects the designing requirement of testing the monitoring alarm device.
Infrared ray transceiving isolator 1 is used for its real-time tranception infrared signal, penetrate mutually between two transceivers of fence when there being personnel to move to infrared double-core, during the blocking-up infrared signal, infrared ray transceiving isolator 1 is namely exported triggering signal to power supply partition apparatus 2 and display alarm device 3
