[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] See below Figure 1 , Figure 1 A flow chart of a radiator control method provided in an embodiment of the present application.

[0057] Specific steps may include:

[0058] S101: Controlling the radiator motor to rotate forwardly so as to drive the hydraulic oil to circulate between the radiator body and the oil tank;

[0059] Among them, this embodiment can be applied to the controller of the device where the radiator is located. The above-mentioned radiator includes a radiator body and a radiator motor, and the radiator body is connected to the oil tank. When the radiator motor is working, it can drive the hydraulic oil to circulate between the radiator body and the oil tank. The radiator body is the main place for heat exchange, and the heat in the oil tank is transferred to the environment through its internal pipes and external heat sinks. Specifically, the radiator motor is an electric motor that drives the heat pump, and it drives the hydraulic oil to circulate between the radiator body and the oil tank through forward rotation.

[0060] Before this step, there may be an operation of accepting a start instruction, at which time the device where the radiator is located performs a corresponding operation, and the radiator motor in the radiator rotates forward to drive the hydraulic oil to circulate between the radiator body and the oil tank.

[0061] S102: Detecting the oil temperature of the hydraulic oil in the oil tank;

[0062] In this embodiment, a temperature sensor may be arranged inside the oil tank, and the temperature sensor may be used to detect the oil temperature of the hydraulic oil inside the oil tank.

[0063] S103: If the oil temperature is greater than or equal to a preset temperature value, determining whether the radiator is faulty;

[0064] Before this step, there may be an operation to determine whether the oil temperature of the hydraulic oil in the oil tank is greater than or equal to the preset temperature value. If the oil temperature is greater than or equal to the preset temperature value, it means that the radiator is faulty or contaminated. When the oil temperature is greater than or equal to the preset temperature value, this embodiment determines whether the radiator is faulty. The above faults may include radiator motor faults, sensor faults, control system faults, connection pipeline faults, etc. If the radiator is faulty, the process may be terminated and a fault prompt message may be output; if the radiator is not faulty, the relevant operations of S104 may be entered. The contamination mentioned in this embodiment does not constitute a fault.

[0065] S104: If the radiator is not faulty, obtaining a state parameter of the radiator;

[0066] Among them, this step is based on the fact that the radiator does not have any faults. At this time, the state parameters of the radiator can be obtained, and the above-mentioned state parameters are parameters describing the contamination state of the radiator. The above-mentioned state parameters include temperature difference and may also include wind pressure difference. The temperature difference is the difference between the oil inlet temperature and the oil outlet temperature of the radiator, and the wind pressure difference is the difference between the air outlet pressure and the air inlet pressure of the radiator.

[0067] As a feasible implementation method, the temperature difference is equal to the value of the oil inlet temperature minus the oil outlet temperature, and the wind pressure difference is equal to the value of the air outlet pressure minus the air inlet pressure.

[0068] S105: Determine whether the state parameter is within the abnormal range; if so, proceed to S106; if not, end the process;

[0069] Among them, contamination reduces the effective heat transfer area, resulting in a decrease in heat exchange capacity, which leads to a decrease in the difference between the oil inlet temperature and the oil outlet temperature. Contamination increases the resistance to air flow, resulting in an increase in the pressure difference between the air inlet and the air outlet. The smaller the temperature difference, the higher the degree of contamination of the radiator; the greater the wind pressure difference, the higher the degree of contamination of the radiator. In this embodiment, a critical temperature value corresponding to the temperature difference can be set, and a critical wind pressure difference corresponding to the wind pressure difference can also be set.

[0070] When the state parameter includes a temperature difference, if the temperature difference is greater than or equal to a critical temperature value, it indicates that the state parameter is not within an abnormal range; if the temperature difference is less than the critical temperature value (such as a first value), it indicates that the state parameter is within an abnormal range.

[0071] When the state parameter includes the wind pressure difference, if the wind pressure difference is less than or equal to the critical wind pressure difference, it means that the state parameter is not within the abnormal range; if the wind pressure difference is greater than the critical wind pressure difference (such as the third value), it means that the state parameter is within the abnormal range.

[0072] If the status parameter is not within the abnormal range, it means that the degree of contamination of the radiator is less than or equal to the critical degree, and the process can be terminated; if the status parameter is within the abnormal range, it means that the degree of contamination of the radiator is greater than the critical degree, and the cleaning operation is performed.

[0073] S106: Control the radiator motor to rotate in the reverse direction to remove the dirt in the radiator.

[0074] This step is based on the state parameter being in an abnormal range. At this time, the radiator motor can be controlled to rotate in the reverse direction to remove the contamination in the radiator. As a feasible implementation, this embodiment can control the radiator motor to rotate in the reverse direction at the maximum speed. The contamination in the radiator may include impurities such as dust, oil, and smoke.

[0075] This embodiment controls the radiator motor to rotate forward to drive the hydraulic oil to circulate between the radiator body and the oil tank, ensuring that heat is transferred from the oil tank to the radiator and dissipated to the environment through the radiator. This embodiment detects the oil temperature of the hydraulic oil in the oil tank, and obtains the state parameters of the radiator, such as temperature difference and / or wind pressure difference, when the oil temperature is greater than or equal to the preset temperature value and there is no fault in the radiator. This embodiment determines whether the obtained state parameters are within the abnormal range; if the state parameters are within the abnormal range, it means that the radiator is not contaminated; if the state parameters are not within the abnormal range, it means that the radiator is contaminated, and the radiator motor can be controlled to rotate in the opposite direction. The reverse rotation of the radiator motor can produce an eddy current effect, which helps to remove the contamination inside the radiator and restore its heat dissipation performance. Therefore, this embodiment can automatically detect the state of the radiator and increase the service life of the radiator.

[0076] As for Figure 1 Further introduction to the corresponding embodiment, when the state parameter is in the abnormal range, a specific time can be selected to control the radiator motor to rotate in the reverse direction, specifically as follows: detect whether the key switch of the device where the radiator is located is disconnected; if so, control the radiator motor to rotate in the reverse direction for a preset time; after the radiator motor rotates in the reverse direction, disconnect the power supply of the device to shut down. The above process can be cleaned during the delayed shutdown stage to avoid interference of the cleaning process with normal work.

[0077] As for Figure 1 As a further introduction to the corresponding embodiment, if the state parameter includes a temperature difference, it can be determined whether the temperature difference is less than a first value; if so, it is determined that the state parameter is within the abnormal range.

[0078] Correspondingly, this embodiment can further determine whether the temperature difference is less than a second value; if so, the radiator is determined to be in a manual cleaning state, and a prompt message corresponding to the manual cleaning state is generated; if not, the radiator is determined to be in an automatic cleaning state, and a prompt message corresponding to the automatic cleaning state is generated. Wherein, the second value is less than the first value. The automatic cleaning state refers to a state in which the contamination can be removed by reverse rotation of the radiator motor, and the manual cleaning state refers to a state in which the contamination can be removed by reverse rotation of the radiator motor and combined with manual processing.

[0079] As for Figure 1 Further introduction to the corresponding embodiment, if the state parameter includes a wind pressure difference, it can be determined whether the wind pressure difference is greater than a third value; if so, it is determined that the state parameter is within the abnormal range;

[0080] Correspondingly, this embodiment can further determine whether the wind pressure difference is greater than a fourth value; if so, determine that the radiator is in a manual cleaning state, and generate prompt information corresponding to the manual cleaning state; if not, determine that the radiator is in an automatic cleaning state, and generate prompt information corresponding to the automatic cleaning state. Wherein, the fourth value is greater than the third value.

[0081] If the temperature difference is greater than or equal to the first value, and the wind pressure difference is less than or equal to the third value, it means that the degree of contamination of the radiator is less than or equal to the critical degree, and no cleaning operation is required.

[0082] As for Figure 1 For further description of the corresponding embodiment, it can be determined whether the radiator is faulty by the following methods:

[0083] Method 1: Obtain the current current value of the heat pump solenoid valve; obtain the current speed value of the radiator motor; determine whether the current current value matches the current speed value; if not, determine that the radiator is faulty. The heat pump solenoid valve is used to adjust the speed of the radiator motor by controlling the displacement of the heat pump hydraulic pump; this embodiment can pre-store the corresponding relationship between the current value of the heat pump solenoid valve and the speed value of the radiator motor.

[0084] Method 2: Obtain the current current value of the heat pump solenoid valve; obtain the current pipeline pressure of the oil inlet pipeline connecting the radiator motor and the heat pump; determine whether the current current value matches the current pipeline pressure; if not, determine that the radiator is faulty. The heat pump solenoid valve is used to control the displacement of the heat pump; this embodiment can pre-store the corresponding relationship between the current value of the heat pump solenoid valve and the current pipeline pressure of the oil inlet pipeline.

[0085] The process described in the above embodiment is explained below through an embodiment in actual application.

[0086] After long-term use, the radiator of the independent cooling system of a large excavator will be contaminated and the heat dissipation capacity will decrease. At present, there is no way to detect the degree of contamination of the radiator. Only when the operator observes that the hydraulic oil is at high temperature during operation, will it use manual reversal of the cooling fan or water flushing to clean it. At this time, the contamination is often serious and it is very difficult or difficult to clean thoroughly. At the same time, there is no monitoring and warning for the decrease in the heat dissipation capacity of the radiator caused by problems in other links of the cooling system. When problems occur, the cooling system cannot be maintained quickly and easily, resulting in reduced work efficiency. This system uses a new type of radiator and heat dissipation monitoring system to monitor the status of each key link of the radiator and the cooling system in real time, issue warnings when abnormalities occur, and automatically clean or prompt manual intervention, solving the problem of difficult maintenance and overhaul of the cooling system and improving the service life and simplicity of the cooling system.

[0087] See also Figure 2 , Figure 2 The schematic diagram of the structure of an excavator radiator maintenance system provided in an embodiment of the present application includes: a controller, an instrument, a fuel tank temperature sensor, a heat dissipation pump solenoid valve, a forward and reverse solenoid valve, a radiator assembly, a radiator motor speed sensor, an outlet temperature sensor, and an inlet temperature sensor. The heat dissipation pump solenoid valve is used to control the displacement of the heat dissipation hydraulic pump, thereby controlling the speed of the hydraulic motor. In this embodiment, a matching relationship between the current value and the speed can be pre-set. The radiator motor speed sensor, the outlet temperature sensor, and the inlet temperature sensor are arranged in the radiator assembly and connected to the controller.

[0088] This solution divides the radiator into three working states: normal working state, automatic cleaning state, and manual cleaning state.

[0089] During the operation of the excavator, the hydraulic oil tank temperature sensor monitors that the hydraulic oil temperature has not reached the preset temperature point, and the radiator is in normal working condition.

[0090] When the hydraulic oil temperature reaches the preset point (i.e., the preset temperature value), the controller compares the current of the cooling pump solenoid valve with the speed value of the radiator motor speed sensor on the radiator assembly to see if they match. If they do not match, the instrument prompts a cooling system failure. If they match, the controller reads the temperature difference between the inlet temperature sensor and the outlet temperature sensor on the radiator assembly. When the temperature difference is less than or equal to the preset value 1 (i.e., the first value) and greater than the preset value 2 (i.e., the second value), the forward and reverse solenoid valve is controlled to reverse the radiator motor for a preset time when the machine is shut down to clean the radiator, and the instrument displays that the radiator enters the self-cleaning state at this time.

[0091] The machine has a delayed shutdown setting. If the temperature difference is less than or equal to the preset value 1 and greater than the preset value 2, the machine will not shut down immediately after the key switch is turned off. At this time, the radiator will be reversed immediately. The machine will shut down after the controller disconnects the power supply after waiting for the radiator to reverse. The above shutdown refers to the shutdown of the excavator, that is, the key switch is powered off, the engine is shut down, and the power of the whole machine is disconnected.

[0092] Furthermore, when the hydraulic oil temperature reaches a preset point, the controller compares the current of the cooling pump solenoid valve with the speed value of the radiator motor speed sensor on the radiator assembly. If they do not match, the instrument prompts a cooling system failure. If they match, the controller reads the temperature difference between the inlet temperature sensor and the outlet temperature sensor on the radiator assembly. When the temperature difference is less than or equal to the preset value 2, the controller controls the forward and reverse solenoid valves to reverse the radiator motor for a preset time when the machine is shut down to clean the radiator. At the same time, the instrument warns you to clean the radiator manually, and the instrument displays that the radiator has entered the manual cleaning state.

[0093] See also Figure 3 , Figure 3 A flow chart of a method for cleaning an excavator radiator provided in an embodiment of the present application, the process of which is as follows: determine whether the oil tank temperature has reached a preset point; if so, determine whether the current value of the heat pump solenoid valve matches the speed value of the heat dissipation motor. If they do not match, the instrument is used to prompt a heat dissipation system failure; if they match, determine whether the radiator temperature difference (i.e., the temperature difference between the inlet and outlet oil ports) is less than or equal to a preset value 1. If it is not less than the preset value 1, the process ends; if it is less than the preset value 1, determine whether the radiator temperature difference is less than or equal to a preset value 2. If it is less than or equal to the preset value 2, the radiator automatically reverses for a preset time when the machine is shut down, and the instrument is used to warn the radiator and remind the radiator to enter a manual cleaning state; if it is greater than the preset value 2, the radiator automatically reverses for a preset time when the machine is shut down, and the instrument is used to display that the radiator enters a self-cleaning state.

[0094] This embodiment monitors the radiator status through radiator inlet and outlet temperature sensors, confirms the cooling system status by comparing the cooling pump solenoid valve current and the cooling motor speed match, and also confirms the radiator status by comparing the temperature difference and performs reverse self-cleaning and manual cleaning reminders.

[0095] In this embodiment, the inlet and outlet temperature sensors can be installed on other inlet and outlet oil circuits. In this scheme, the radiator assembly is integrated with the temperature sensor installation at the hydraulic oil inlet and outlet positions. The temperature sensor is not necessarily installed on the radiator, but can also be installed on the pipe joint of the inlet and return oil, such as the interface position of the return oil pipe in the oil tank. The above-mentioned matching of the heat pump solenoid valve current and the heat dissipation motor speed can be implemented by means of oil circuit pressure and the like. In this embodiment, the motor speed is monitored by the heat dissipation motor speed sensor, and then matched and compared with the heat dissipation pump solenoid valve current, which is more accurate. When the heat dissipation motor is working, at different speeds, the oil inlet pipeline pressure connecting the heat dissipation motor and the heat dissipation pump is inversely proportional to the heat dissipation pump current value and proportional to the heat dissipation motor speed. The larger the heat dissipation pump solenoid valve current value, the smaller the pressure value, and the lower the heat dissipation motor speed. In this way, the heat dissipation motor speed can be indirectly determined by establishing a relationship between the heat dissipation pump solenoid valve current value and the pressure value, and the oil circuit pressure value can be obtained by the pressure sensor and compared with the current heat dissipation pump solenoid valve preset value. The above-mentioned radiator state monitoring can also increase the inlet and outlet pressure difference to optimize this scheme. The above-mentioned inlet and outlet pressure difference refers to the pressure difference between the radiator inlet and outlet, that is, the front and back air pressure difference when the radiator is working. In this embodiment, the heat dissipation motor can be reversed just after starting the engine or after starting and stopping.

[0096] This embodiment can monitor the status of the key links of the radiator and the cooling system in real time, issue an alarm in case of abnormality, and perform automatic cleaning or prompt manual intervention, thereby solving the problem of difficult maintenance and overhaul of the cooling system and improving the service life and simplicity of the cooling system.

The reverse rotation of the radiator motor can produce an eddy current effect, which helps to remove the contamination inside the radiator and restore its heat dissipation performance. Therefore, this embodiment can automatically detect the state of the radiator and increase the service life of the radiator.

[0104] Furthermore, the process of the contamination cleaning module controlling the reverse rotation of the radiator motor includes: detecting whether the key switch of the device where the radiator is located is disconnected; if so, controlling the radiator motor to rotate in the reverse direction for a preset time; after the reverse rotation of the radiator motor is completed, disconnecting the power supply of the device to shut down the engine.
