The control unit 2 controls the opening degrees of the first and second flow rate adjustment solenoid valves 9 and 14 and the rotation speeds of the first and second heat dissipation fans 41 and 121, respectively, based on the temperature signals of the first, second, third, and fourth temperature sensors 3, 10, 11, and 15.
The specific structure of the control unit 2 is shown in fig. 2, and includes a temperature sensor interface module 201, a first signal conditioning module 202, a processor module 203, a DA conversion module 204, a second signal conditioning module 205, a combination control module 206, an electromagnetic valve interface module 207, a PWM control module 210, a cooling fan interface module 211, a CAN transceiver module 208, a logic monitoring module 209, and a power supply module 212, which are connected in sequence.

The logic monitor module 209 is used to detect system circuit faults and transmit fault signals to the processor module 203. The power supply module 212 is used to supply power to the other respective modules of the control unit 2.
The intelligent energy-saving water cooling system provided by the utility model is an improvement on the water cooling system of the existing diesel locomotive, and realizes the regulation and control of the flow regulating electromagnetic valve and the radiating fan by adding the flow regulating electromagnetic valve in a cooling water loop, installing temperature sensors at a cooling water outlet and an inlet of a diesel engine and utilizing a control unit based on temperature signals.
The system has three working modes, namely an automatic operation mode, a constant value operation mode and a set operation mode.
After the diesel locomotive starts, the energy-conserving water cooling system of intelligence begins to operate with automatic operation mode, and the high temperature cooling water export and the entrance temperature of diesel engine 1 are gathered respectively to first temperature sensor 3 and second temperature sensor 10, and the low temperature cooling water export and the entrance temperature of diesel engine 1 are gathered respectively to third temperature sensor 11 and fourth temperature sensor 15 to send temperature signal to control unit 2. The control unit 2 automatically adjusts the opening degrees of the first flow regulating solenoid valve 9 and the second flow regulating solenoid valve 14 and the rotating speeds of the first cooling fan 41 and the second cooling fan 121 according to a preset PID control algorithm, so that when the temperature of the diesel engine 1 is low, the flow rate of cooling water in the cooling water loop is correspondingly low, and the rotating speeds of the first cooling fan 41 and the second cooling fan 121 are low, thereby saving energy consumption; when the temperature of the diesel engine 1 is high, the flow rate of the cooling water in the cooling water circuit is also correspondingly high, and the rotating speeds of the first cooling fan 41 and the second cooling fan 121 are high, so as to perform rapid cooling, thereby achieving the best cooling effect.
In addition, a driver CAN also send an instruction through CAN communication to control the operation of the intelligent energy-saving water cooling system, namely a constant value operation mode and a set operation mode.
The constant value operation mode is that the fixed opening values of the first flow regulating electromagnetic valve 9 and the second flow regulating electromagnetic valve 14 are sent to the control unit 2 through CAN communication, the CAN transceiver module 208 receives the instruction and transmits the instruction to the processor module 203, and the processor module 203 controls the opening degrees of the first flow regulating electromagnetic valve 9 and the second flow regulating electromagnetic valve 14 according to the given opening values.
The operation mode is set to be that a group of system operation parameters are sent to the control unit 2 through CAN communication, the CAN transceiving module 208 receives instructions and transmits the instructions to the processor module 203, and the processor module 203 controls the opening degrees of the first flow regulating electromagnetic valve 9 and the second flow regulating electromagnetic valve 14 according to the given system operation parameters. The system operation parameters comprise operation curves, operation time and the like, and the mode is mainly used when the optimal cooling parameters are obtained in the system debugging stage.
Once the intelligent energy-saving water cooling system breaks down, the intelligent energy-saving water cooling system cannot normally run, and the diesel engine 1 is damaged due to insufficient cooling. In order to ensure the reliability of the system, a logic monitoring module 209 is added to the control unit 2 to implement a fault locking function. The logic monitoring module 209 monitors the system circuit in real time during the operation process, and if a fault is found, transmits a fault signal to the processor module 203 immediately, and the processor module 203 controls the first flow regulating solenoid valve 9 and the second flow regulating solenoid valve 14 to have the maximum opening degree and outputs the fault signal through the CAN transceiver module 208.
The specific structure of the logic monitoring module 209 is shown in fig. 3, wherein the fault signal is to determine whether the output signal collected by the processor module 203 matches the input signal, and if not, the fault signal is to control the output circuit to fail, and then the fault signal is output; the watchdog signal is used for detecting whether the processor module 203 normally operates or not, and outputting the signal if the processor module 203 cannot normally operate; the reset signal is used for detecting whether the power supply is normal or not, and outputting the signal if the power supply is abnormal.
The system does not control the water pump to work, because the water pump can automatically detect the pressure in the working process, and can automatically stop running when the pressure reaches a certain value, so the water pump can be indirectly controlled to work only by controlling the flow regulating electromagnetic valve, and the cost of controlling the flow regulating electromagnetic valve is lower than that of controlling the water pump.
