By describing technology contents of the present utility model, structural attitude in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, a kind of infrared intrusion detector of present embodiment, this infrared intrusion detector comprises master control set 1 and at least one Infrared Intrusion Detection device 2, wherein, Infrared Intrusion Detection device 2 is arranged at the diverse location in the region of deploying to ensure effective monitoring and control of illegal activities, some main Vomitory mouths particularly, as positions such as corridor, window, doorways.
Described master control set 1 comprises first processor 11 and the alarm unit 12 being connected with first processor and the first wireless two-way radio frequency unit 13; Described Infrared Intrusion Detection device 2 comprises that the second processor 22, the second wireless two-way radio frequency unit 21, infrared electricity release probe 24, signal amplification unit 23 and power control unit 25; Described the second processor 22 is connected with the second wireless two-way radio frequency unit 21; The input end of described signal amplification unit 23 is connected with the output terminal that infrared electricity is released probe 24, and the output terminal of signal amplification unit 23 is connected with the second processor 22; The input end of described power control unit 25 is connected with the second processor 22, and the output terminal of power control unit 25 is connected with the control end of signal amplification unit 23.Described master control set 1 and Infrared Intrusion Detection device 2 are by the first wireless two-way radio frequency unit 13 and the second wireless two-way radio frequency unit 21 communication connections.
As shown in Figure 2, in the present embodiment, described power control unit 25 comprises the first metal-oxide-semiconductor, the first resistance and the second resistance; One end of described the first resistance is connected in the output terminal of the second processor 22, and the other end of the first resistance is connected with one end of the second resistance, the other end ground connection of the second resistance; The grid of described the first metal-oxide-semiconductor is connected with the common point of the second resistance with the first resistance, and the drain electrode of the first metal-oxide-semiconductor is connected with the control end of signal amplification unit 23, the source ground of the first metal-oxide-semiconductor.
Described signal amplification unit 23 comprises the first triode; The base stage of described the first triode is released probe 24 output with the drain electrode of described the first metal-oxide-semiconductor, infrared electricity respectively and is connected, the grounded emitter of the first triode, and the collector of the first triode is connected with the second processor 22.
When the second processor 22, do not receive while deploying troops on garrison duty that (while being disarming state) controls the pin being connected with the first resistance and be output as high level, now, the bank tube of the first metal-oxide-semiconductor is high level, the first metal-oxide-semiconductor conducting, the base earth of the first triode, the first triode is processed into static schema, power consumption is minimum, because the first triode is processed quiet state, therefore infrared electricity is released probe 24 ground connection, and its input signal also cannot be sent to the second processor 22.
When the second processor 22, receive while deploying troops on garrison duty that (being while deploying troops on garrison duty state) controls the pin being connected with the first resistance and be output as low level, now, the bank tube of the first metal-oxide-semiconductor is low level, the first metal-oxide-semiconductor cut-off, the base earth of the first triode, the first triode is processed into amplification mode, because the first triode is in quiet state, therefore infrared electricity is released probe 24 and is connected with the base stage of the first triode, and its input signal is sent to the second processor 22 after the first triode amplification.
