[0031] The present invention will be further described below in conjunction with the drawings and embodiments.

[0032] As Figures 1-6 shown, the launching device monitor for blasting mine-sweeping includes:

[0033] A signal acquisition circuit, a single-chip microcomputer, and a display screen; the signal acquisition circuit is electrically connected to the circuit of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be acquired and the single-chip microcomputer. The signal acquisition circuit is used to acquire the signal of the circuit of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be acquired and send it to the single-chip microcomputer; the single-chip microcomputer is electrically connected to the display screen, and the single-chip microcomputer sends the acquired signal of the circuit of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be acquired to the display screen for display. In this way, through the signal acquisition circuit, the signal of the circuit of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be acquired is acquired and sent to the single-chip microcomputer; then the single-chip microcomputer sends the acquired signal of the circuit of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be acquired to the display screen for display. In this way, the signal voltage and signal current of the circuit of the fire control system of the blasting mine-sweeping launching device including the mine-sweeping vehicle can be sent to the single-chip microcomputer and displayed through the display screen, and the performance detection of the signal voltage and signal current of the circuit of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle can be realized, effectively avoiding the defect that there is no device for detecting the signal voltage and signal current performance of the circuit of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle in the prior art.

[0034] The single-chip microcomputer is of the STM32 type. The signal acquisition circuit includes a voltage signal acquisition circuit. The voltage signal acquisition circuit includes a full-bridge rectifier circuit U1. Since the lines of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signals are to be acquired are generally AC signals, the AC signals need to be converted into DC signals by the full-bridge rectifier circuit U1 before being transmitted to the single-chip microcomputer. In addition, whether the AC signal is a positive voltage or a negative voltage, it can be converted into a positive voltage by the full-bridge rectifier circuit, enabling the subsequent detection circuit to detect correctly. The two ends of the full-bridge rectifier circuit U1 are respectively electrically connected to the two ends of the line of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signals are to be acquired. The other two ends of the full-bridge rectifier circuit U1 are respectively grounded and electrically connected to one end of a fuse F1. The end of the fuse F1, one pole of a capacitor C1, one end of a resistor R4, and one end of a resistor R5 are electrically connected. The other pole of the capacitor C1 is grounded. The capacitor C1 can play a role in filtering the line where it is located. The other end of the resistor R5, one end of a resistor R6, one end of a bidirectional voltage regulator diode D3, and one end of a resistor R28 are electrically connected. The other end of the bidirectional voltage regulator diode D3 and the other end of the resistor R6 are both grounded. The bidirectional voltage regulator diode D3 can play a role in stabilizing the voltage of the line where it is located. The other end of the resistor R28 is electrically connected to the 1st pin of an operational amplifier U5. The 3rd pin of the operational amplifier U5, one end of a resistor R27, one end of a resistor R26, and one pole of a capacitor C13 are electrically connected. The other end of the resistor R26, the other pole of the capacitor C13, one end of a ninth resistor R33, and the 5th pin of the operational amplifier U5 are electrically connected. The 2nd pin of the operational amplifier U5 is grounded. The 3rd pin of the operational amplifier U5 is electrically connected to a 3.3V voltage source. The resistor R26 and the capacitor C13 form an RC filter circuit, which can filter the line where it is located. The other end of the ninth resistor R33, one pole of a capacitor C17, and the 13th pin of the STM32 single-chip microcomputer are electrically connected. The other pole of the capacitor C17 is grounded. The capacitor C17 can play a role in filtering the line where it is located. In this way, the AC signal from the line of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signals are to be acquired can be converted into a DC signal by the full-bridge rectifier circuit U1, and then the DC signal can be amplified by the operational amplifier U5 and sent into the STM32 single-chip microcomputer.

[0035] The signal acquisition circuit further includes a current signal acquisition circuit, and the current signal acquisition circuit includes the opto-relay U15; the other end of the fuse F1, one end of the resistor R1, and the collector of the transistor Q1 are electrically connected, the other end of the resistor R1, one pole of the capacitor C30, the base of the transistor Q1, and the pin 6 of the opto-relay U15 are electrically connected, the pin 4 of the opto-relay U15 is grounded, the pin 1 of the opto-relay U15 is electrically connected to the 3.3V voltage source VDD, and the 3.3V voltage source VDD can be the positive electrode of a 3.3V lithium battery, and the negative electrode of the 3.3V lithium battery is grounded; the other pole of the capacitor C30 is grounded, and the resistor R1 and the capacitor C30 form an RC filter circuit, which can filter the line where it is located; the pin 2 of the opto-relay U15 and one end of the resistor R3 are electrically connected, the other end of the resistor R3 and the pin 16 of the STM32 single-chip microcomputer are electrically connected, the emitter of the transistor Q1, the collector of the transistor Q3, and one end of the resistor R2 are electrically connected, the other end of the resistor R2, the base of the transistor Q3, and one pole of the capacitor C31 are electrically connected, the other pole of the capacitor C31 is grounded, and the resistor R2 and the capacitor C31 form an RC filter circuit, which can filter the line where it is located; the emitter of the transistor Q3, the pin 1 of the ACS722 current sensor, and the pin 2 of the ACS722 current sensor are electrically connected, the pin 8 of the ACS722 current sensor, the 3.3V voltage source VDD, and one pole of the capacitor C21 are electrically connected, the other pole of the capacitor C21 is grounded, and the capacitor C21 filters the line where it is located, and the 3.3V voltage source VDD is used to supply power to the ACS722 current sensor, the pin 5 of the ACS722 current sensor, the pin 6 of the ACS722 current sensor, and one pole of the capacitor C15 are all grounded, and the capacitor C15 filters the line where it is located, the other pole of the capacitor C15, the pin 7 of the ACS722 current sensor, and one end of the resistor R31 are electrically connected, the other end of the resistor R31 and the pin 1 of the operational amplifier U6 are electrically connected, the pin 3 of the operational amplifier U6, one end of the resistor R30, one end of the resistor R29, and one pole of the capacitor C14 are electrically connected, the other end of the resistor R30 is grounded, and the resistor R29 and the capacitor C14 form an RC filter circuit, which can filter the line where it is located; the other end of the resistor R29, the other pole of the capacitor C14, the pin 4 of the operational amplifier U6, and one end of the resistor R34 are electrically connected, the pin 5 of the operational amplifier U6 is electrically connected to the 3.3V voltage source, the pin 2 of the operational amplifier U6 is grounded, and the other end of the resistor R34 and the pin 14 of the STM32 single-chip microcomputer are electrically connected.In this way, the AC signal of the line of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be collected can be converted into a DC signal through the full-bridge rectifier circuit U1. Then, after being sent into the first triode in the conducting state and amplified by the first triode, the DC signal is sent into the second triode for further amplification, and then sent into the ACS722 type current sensor to form a current signal. Then, the operational amplifier U5 amplifies the current signal and sends it into the STM32 single-chip microcomputer. Additionally, under normal circumstances, the 16th pin of the STM32 single-chip microcomputer outputs a low level, so that the opto-coupler relay U15 is in the conducting state, and the ACS722 type current sensor can normally receive the signal on the line. When it is not necessary to collect the current signal of the line, the 16th pin of the STM32 single-chip microcomputer outputs a high level, so that the opto-coupler relay U15 is in the cut-off state, and the ACS722 type current sensor can terminate receiving the signal on the line. Such a control method is more flexible.

[0036] The signal acquisition circuit further includes a duration signal acquisition circuit; the duration signal acquisition circuit includes an HCPL-0631 type opto-coupler U4; the other end of the first resistor R4 is electrically connected to the positive electrode of the first diode D1, the negative electrode of the first diode D1 is electrically connected to the 1st pin of the HCPL-0631 type opto-coupler U4, the 2nd pin, the 3rd pin, the 4th pin and the 5th pin of the HCPL-0631 type opto-coupler U4 are grounded, the 8th pin of the HCPL-0631 type opto-coupler U4, the 3.3V voltage source, one pole of the ninth capacitor C16 and one end of the fifteenth resistor R9 are electrically connected, the other pole of the ninth capacitor C16 is grounded, and the ninth capacitor C16 filters the line where it is located. The other end of the fifteenth resistor R9, the 11th pin of the STM32 single-chip microcomputer and the 2nd pin of the HCPL-0631 type opto-coupler U4 are electrically connected. In this way, after a signal is generated in the line of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be collected, the opto-coupler U4 conducts, and the voltage at its output end flips. Thus, the signal sent into the single-chip microcomputer can start the timer of the single-chip microcomputer. When the signal in the line of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be collected disappears, the output signal of the opto-coupler U4 will flip again. Thus, the signal sent into the single-chip microcomputer can turn off the timer of the single-chip microcomputer, so that the continuous duration of the signal generated in the line of the fire control system of the blasting mine-sweeping launching device of the mine-sweeping vehicle whose signal is to be collected can be obtained and recorded.

[0037] The monitor for the launching device used for blasting mine clearance further includes a current-limiting fine-tuning circuit; the current-limiting fine-tuning circuit includes a ULN2003 type transistor array U3.

The other end of the eighteenth resistor R19, the other end of the nineteenth resistor R20, one end of the twenty-second resistor R17, and one end of the twenty-third resistor R18 are electrically connected. The 12th pin and the 10th pin of the ULN2003 type transistor array U3 are respectively electrically connected to the 2nd pin and the 4th pin of the second HFE7-3-1HT-L2 type electromagnetic relay RL1.

In this way, different signals can be output by the single-chip microcomputer to make the ULN2003 composite transistor array output corresponding signals to control the conduction or cut-off of different resistances between the electromagnetic relay two RL2 and the electromagnetic relay one RL1 and the current sensor. Thus, the conduction or cut-off of different resistances between the electromagnetic relay two RL2 and the electromagnetic relay one RL1 and the current sensor and the conduction or cut-off of the current sensor can be achieved. Therefore, the current signal output by the current sensor can be adjusted more flexibly to better adapt to the signal input requirements of various different models of single-chip microcomputers, enhancing the flexibility of the monitoring instrument of the blasting mine-sweeping launching device. Thus, current limiting fine-tuning is carried out to match the needs of different detection equipment.
