Abstract
The utility model relates to an induction detection device comprising an antenna magnetic field induction circuit and a single-chip microcomputer control circuit. A signal acquired by the antenna magnetic field induction circuit can be transmitted to the single-chip microcomputer control circuit. An output signal of the single-chip microcomputer control circuit can be transmitted to a ZigBee wireless module circuit, and an output signal of the ZigBee wireless module circuit can be transmitted to a data processing center. According to the utility model, the antenna magnetic field induction circuit can be used to acquire the voltage single, and the ZigBee wireless module can be driven to send the alarming information to the duty center after the determination of the single-chip microcomputer control circuit. The device can be used to receive the alarming information from a plurality of workers at the same time by adopting a honeycomb-type transmission.
Description
Technical field
The utility model relates to a kind of sniffer, particularly be a kind of induction sniffer.
Background technology
When the electrician personnel overhauled at charged work, most separate operaton that adopts had certain risk, when so in a single day electric shock accidents taking place, can not in time require assistance.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of induction sniffer is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of induction sniffer, comprise antenna magnetic field sensor circuit and single chip machine controlling circuit, the signal of described antenna magnetic field sensor circuit collection is delivered to single chip machine controlling circuit, the output signal of described single chip machine controlling circuit is sent to ZigBee wireless module circuit, and the output signal of described ZigBee wireless module circuit sends to data processing centre (DPC).
Described antenna magnetic field sensor circuit adopts induction electrode T1 to gather signal, and the output terminal of described induction electrode T1 connects field effect transistor Q1 and transistor VT1 unusually.
Described field effect transistor Q1 adopts the 3DJ6 field effect transistor.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model is gathered voltage signal by the antenna magnetic field sensor circuit, after the single chip machine controlling circuit judgement, drive the ZigBee wireless module to center on duty, send warning message, this device adopts cellular transmission, can receive several staff's warning message simultaneously.
Description of drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of induction sniffer of the present utility model, comprise antenna magnetic field sensor circuit 1 and single chip machine controlling circuit 2, the signal that described antenna magnetic field sensor circuit 1 is gathered is delivered to single chip machine controlling circuit 2, the output signal of described single chip machine controlling circuit 2 is sent to ZigBee wireless module circuit 21, and the output signal of described ZigBee wireless module circuit 21 sends to data processing centre (DPC) 211.
Described antenna magnetic field sensor circuit 1 adopts induction electrode T1 to gather signal, the output terminal of described induction electrode T1 connects 3DJ6 field effect transistor Q1 and transistor VT1 unusually, as induction electrode T1 during away from the high pressure object, resistance between the leakage one source pole of 3DJ6 field effect transistor Q1 is less, respective transistor VT1 is in cut-off state because base potential is lower, transistor VT1 is in cut-off state, the 18th pin of 2051 single-chip microcomputer IC1 also is high level state, after 2051 single-chip microcomputer IC1 judge, do not send control signal.
As induction electrode T1 during near the high pressure object, induction electrode T1 has the induction electric field signal, resistance between the leakage one source pole of 3DJ6 field effect transistor Q1 becomes big at this moment, transistor VT1 pipe is because of base potential rising conducting, the 18th pin of 2051 single-chip microcomputer IC1 is low level state, after the identification of 2051 single-chip microcomputer IC1 internal processes, by the 6th of ZM2410 wireless communication module IC2, the 2nd of 7 ends and 2051 single-chip microcomputer IC1,3 ends are formed ZigBee wireless module circuit 21, ZM2410 wireless communication module IC2 is the embedded serial ports transparent transmission of the Zigbee of built-in 2.4GHZ (some multiple spot and point-to-multipoint) communications protocol, supports aerial upgrade firmware or configuration far module information.Up to the output of the power of 7dBm and-receiving sensitivity of 100dBm, can satisfy telecommunication, send the AT instruction by 2051 single-chip microcomputer IC1 ZM2410 wireless communication module IC2 is realized wireless data transceiving, switch pin with the RS-485 direction, send assistance message to center on duty, realize in time handling, avoid the generation of personnel casualty accidents, be have that networking is simple, cost is low, the new generation of wireless of dependable performance transmission warning device, this device adopts cellular transmission, can receive several staff's warning message simultaneously.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
