The working principle of the present embodiment is explained in detail as follows:
at the job site of track board installation, can follow the shift along with the position of the laying job site of track board, so generally to supply power for various equipment instrument be the temporary lap joint power, partly still can use the generator to carry out the temporary power supply. The power supply capability of the power supplies is unstable, and the problems of undervoltage, overvoltage, overcurrent, surge and the like often occur. When the Zigbee module communication protocol converter performs protocol conversion on the acquired data, if the above problems are encountered, the data format conversion may be affected, and situations such as data conversion errors may occur. An overvoltage protection circuit, an overcurrent protection circuit, a surge protection circuit and a voltage stabilizing circuit are added on a power module of the Zigbee module communication protocol converter.
As shown in fig. 2, the overvoltage protection circuit includes a first diode D1, a first resistor R1, a first capacitor C1, a first triode Q1, and a first relay K1; the positive electrode of the first diode D1 is connected with the input end of the circuit, and the negative electrode is connected with the base electrode of the first triode Q1; one end of the first resistor R1 is connected with the cathode of the first diode D1, and the other end is connected with the output end of the circuit; one end of the first capacitor C1 is connected with the base electrode of the first triode Q1, and the other end is connected with the output end of the circuit; the collector of the first triode Q1 is connected with the first relay K1, and the emitter is connected with the output end of the circuit; the input end of the first relay K1 is connected with the input end of the circuit, and the output end is connected with the output end of the circuit.
When the input power is normal, the current passing through the first diode D1 is small, the first transistor Q1 is turned off and controls the relay K1 to be in a conducting state. When the current of the input power supply is higher than the normal state value, the current passing through the first diode D1 becomes large, at the moment, the first triode Q1 is saturated and controls the relay to be disconnected, the input circuit is cut off, and therefore the purpose of protecting the rear-stage circuit is achieved. When the input power supply is recovered to be normal, the first triode Q1 is cut off and controls the relay to be in a conducting state, and power supply is automatically recovered. By using the overvoltage protection circuit, when the voltage of the input power supply fluctuates greatly, the influence on data conversion caused by the damage of the post-stage circuit by overvoltage can be avoided.
As shown in fig. 3, the overcurrent protection circuit includes a second diode D2, a third diode D3, a fourth diode D3, a second resistor R2, a third resistor R3, a second capacitor C2, a second transistor Q2, and a third transistor Q3; the anode of the second diode D2 is connected with the cathode of the third diode D3, and the cathode is connected with the input end of the circuit; the anode of the third triode D3 is connected with the base of the second triode Q3, and the cathode is connected with the anode of the fourth diode D4; the anode of the fourth diode D4 is connected to the cathode of the third diode D3, and the cathode is connected to the collector of the third triode Q3; one end of the second resistor R2 is connected with the circuit input end, and the other end is connected with the second capacitor C2; one end of the third resistor R3 is connected with the circuit input end, and the other end is connected with the base electrode of the third triode Q3; one end of the second capacitor C2 is connected with the second resistor R2, and the other end is connected with the emitter of the second triode Q2; the collector of the second triode Q2 is connected with the base of the third triode Q3, and the emitter is connected with the emitter of the third triode Q3; the collector of the third transistor Q3 is connected to the output terminal.
