Embodiment
A kind of vehicle current monitors sensor, including housing, triode and resistance, and described triode and resistance is respectively provided with
In in housing, the collector of described triode is connected with resistance one end, in use, the other end and the positive electricity of reference voltage of resistance
Pressure connection, the collector of triode is connected with signal receiver, the emitter stage and negative pole of triode（Zero line, that is, be grounded）Connection, three
The base stage of pole pipe is connected with needing into the monitored device that horizontal electrical signal is monitored.Carry and use for convenience, described housing can
It is installed on for enclosed construction housing, i.e. described triode and resistance in housing and has been packaged into a complete current monitoring and is passed
Sensor, housing is closed into before enclosed construction available wire class conductor by triode and resistance each need and external equipment
The circuit connecting end of connection is drawn, and the other end of the resistance draws housing by wire I and is used as reference voltage connection end, three
The collector of pole pipe draws housing by wire II and is used as signal output part, and the emitter stage of triode draws housing by wire III
And as negative pole connection end, the base stage of triode draws housing by wire IV and is used as signal monitoring end.In use, resistance
The other end is drawn housing by wire I and is connected with the positive voltage of reference voltage, and the collector of triode draws shell by wire II
Body is connected as signal output and with signal receiver, and the emitter stage of triode is drawn housing by wire III and connected with negative pole
Connect, the base stage of triode draws housing and with needing to be connected into the monitored device that horizontal electrical signal is monitored by wire IV.Described
Reference voltage is that voltage is 5V reference voltages, and described signal receiver is the detectors such as voltmeter, ten thousand tables, ammeter, specifically
Need to connect any class detector can be according to needing to monitor which signal when using depending on, described negative pole is zero line（It is grounded）.
When circuit is to install, by the signal monitoring end being connected with transistor base and the electrical equipment control system to be monitored
System or the connection of electrical and electronic component signal line, the negative pole connection end being connected with transistor emitter is connected with negative pole（Connect
Ground）, the reference voltage connection end that the other end with resistance is connected is connected with 5V reference voltages, by what is be connected with triode collector
Signal output part detects that detector is connected with being used for（The detector of voltage digital conversion is may be viewed by such as ten thousand tables, voltmeter）.
When signal monitoring end monitors electric signal, the electric signal is input to transistor base, opens triode threshold voltage, and at this moment three
Pole pipe collector and emitter stage are turned on, and now reference voltage, resistance and negative pole are equivalent to be formed a closed-loop path, and electric current is from benchmark
Voltage flows to resistance, flow to triode collector again and emitter stage, then flow into negative pole ground connection, and now resistance has electric current to pass through, now
The voltage on voltmeter being connected with signal output part drops to 0.5V by the V of reference voltage 5 of principle, now shows and signal
The monitored electrical apparatus control system of monitoring side connection carries electric current.When the monitored electrical equipment control being connected with signal monitoring end
When system does not have electric current, signal monitoring end does not have electric signal to be flowed into transistor base, does not form the door of triode now
Voltage, then the triode collector be not turned on emitter stage, now reference voltage, resistance and negative pole just do not constitute closed-loop path,
Resistance does not have electric current to flow through, and resistance does not work, and the voltage reference voltage on the voltmeter being now connected with signal output part is kept
Consistent is all 5V.
