SYN synchronizing signal (illuminator 1 and light-receiving device 2 synchronous communication signal, the SYN of illuminator 1 needs and the SYN of light-receiving device 2 docks)
NC light-receiving device 2 alarm signal output ends (two NC are normally closed signal, become and often open during warning).
Embodiment
Electronic grille fence principle of work described in the utility model is: when light-receiving device (2) internal microprocessor MCU is in order to detect certain a branch of Infrared, first synchronous SYN signal is produced by synchronous signal generating circuit, send to illuminator (1) by cable (9), the infrared transmitting tube that notice illuminator (1) opens corresponding light beam is luminous.Light-receiving device (2) Micro-processor MCV opens the corresponding passage wanting receiving beam in analog switch array by logic control circuit simultaneously, when the corresponding infrared transmitting tube of illuminator (1) launches Infrared, light-receiving device (2) receives corresponding infrared receiving tube infrared signal by 8 paths of LEDs signal acquisition circuits, send into signal amplifier and carry out signal amplification process, signal through signal transacting is sent to Micro-processor MCV, the light signal whether Micro-processor MCV receives through logic decision is effective, effective then carry out the scanning of next light beam, move in circles successively and carry out high-velocity scanning.When a certain light beam being detected or a few beam signal is invalid, indicate that object enters surveyed area, light-receiving device (2) Micro-processor MCV then sends alerting signal (NC becomes NO) by alerting signal output circuit, and hummer sounding pipes simultaneously; Again after all light signals are normal, remove and report to the police.
Illuminator (1) operationally, when the synchronous SYN signal receiving light-receiving device (2) and send, synchronizing signal SYN is sent to the Micro-processor MCV of illuminator (1) by illuminator (1) by synchronization signal processing circuit, after illuminator (1) Micro-processor MCV determines to open according to synchronizing signal SYN certain bundle Infrared that light-receiving device (2) requires, transmit control signal to logic control circuit, open passage corresponding in analog switch array by logic control circuit, the infrared transmitting tube of respective channel starts luminescence.In like manner, it is luminous that illuminator (1) opens each infraluminescence pipe according to synchronizing signal SYN successively, coordinates light-receiving device (2) to carry out sector scanning.
Whether illuminator (1) and light-receiving device (2) built in self testing circuit respectively decision logic signal be correct, and incorrect then pilot lamp (7) flash for prompting, light-receiving device (2) can send alerting signal simultaneously.Illuminator (1) and light-receiving device (2) internal electric source module DC-DC are respectively illuminator (1) and light-receiving device (2) internal circuit provides power supply, and follows the buffer action of external power source.
