[0029] Preferably, the base of the transistor Q1 is connected to one end of the resistor R2, and the other end of the collector of the transistor Q1 is connected to the other end of the resistor R2.

[0030] Preferably, a controllable switch module is installed between the input end of the coil power supply monitoring module and the low-voltage end of the electromagnetic coil, and a normally closed switch and a normally open switch are arranged in the controllable switch module. The control end of the controllable switch module is connected to the fifth output end of the main control module, one end of the normally closed switch and one end of the normally open switch are both connected to the input end of the coil power supply monitoring module, the other end of the normally closed switch is connected to the low-voltage end of the electromagnetic coil, and the other end of the normally open switch is connected to the high-voltage end of the battery coil.

[0031] Preferably, the main control module comprehensively controls the controllable switch module according to the output of the power supply control monitoring module and the output of the coil power supply monitoring module when the low-voltage end of the electromagnetic coil is connected.

[0032] In this application, first, a wireless communication module is designed to realize the main control module and remote communication, which is convenient for remote control of the operation of the electromagnetic coil in the valve, and the operation data of the electrical components in the valve can also be obtained remotely. Then, in order to realize battery power supply, since the working voltage of the electromagnetic coil is about 24V, and the voltage of the battery cannot be reached, the first voltage-stabilizing boost module, the second voltage-stabilizing boost module and the rechargeable capacitor are designed. At the same time, regardless of whether the first voltage-stabilizing boost module and the second voltage-stabilizing boost module use triode amplification and boost chip, the boost effect cannot be achieved. Therefore, a rechargeable capacitor is added and designed in this application. After the rechargeable capacitor is powered by the battery, it starts to charge. After charging enough, it also has the effect of pulling up the voltage, and then it can reach about 24V voltage for the electromagnetic coil to work. After that, in order to avoid the battery being in a power supply state when it is not needed, which will increase the useless consumption of the battery, a control-type drive module is designed to realize whether the battery is powered by the control-type drive module under the control of the main control module, thereby reducing the unnecessary power supply of the battery and extending the service life of the battery. Then, in order to realize the monitoring of all power supply circuits, a battery monitoring module, a power supply control monitoring module and a coil power supply monitoring module are used. The battery monitoring module directly monitors the positive electrode of the battery to determine whether the battery can supply power normally; the power supply control monitoring module monitors whether the controlled drive module can output 24v voltage normally to determine whether the first voltage stabilizing boost module, the second voltage stabilizing boost module, the current limiting module, the controlled drive module and the rechargeable capacitor can work normally; the coil power supply monitoring module generally monitors whether the low-voltage end of the electromagnetic coil has normal working voltage to determine whether the MOS tube in the coil direct drive module is working normally; at the same time, the data is jointly monitored, and the power supply control monitoring module is used to monitor whether the controlled drive module outputs 24v voltage and the coil power supply monitoring module monitors whether the electromagnetic Whether the low-voltage end of the coil is the first specified voltage value. If the monitoring control drive module outputs 24v voltage and the low-voltage end of the electromagnetic coil is not the first specified voltage value, it can be determined that the MOS tube in the coil direct drive module is damaged or the line between the high-voltage end of the electromagnetic coil to the control drive module is broken. At this time, the main control module controls the control end of the controllable switch module to access a high level, the normally closed switch is disconnected, and the normally open switch is closed, so that the input end of the coil power supply monitoring module is connected to the high-voltage end of the electromagnetic coil. If the input end of the coil power supply monitoring module detects 24v voltage at this time, it is determined that the MOS tube in the coil direct drive module cannot work normally. If the input end of the coil power supply monitoring module does not detect 24v voltage, it is determined that the circuit between the high-voltage end of the electromagnetic coil to the output end of the control drive module is broken, so as to facilitate maintenance.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
