Description

Technical Field

[0001] The invention relates to the field of calibration technology, and in particular to a calibration system for an intelligent pump. Background Art

[0002] The main function of pump products such as automotive water pumps and urea pumps is to provide the system with a medium with sufficient pressure. In traditional applications, the pump receives the speed control signal from the host computer to control the speed and provide the medium with the required flow rate to the pipeline. Since the pipeline has a limited pressure resistance, a pressure sensor is generally installed at a certain position in the pipeline. When the pressure reaches the set value, the sensor gives a control signal to reduce the speed of the pump or stop it. However, due to the price of the sensor and the complexity of installation, more and more pumps are required to have the function of estimating the pressure in the pipeline. When the pressure reaches the upper limit, in order to avoid damaging the pipeline, the pump adjusts the speed or stops automatically, thereby achieving the purpose of controlling the upper limit of pressure. This is the smart pump.

[0003] The principle of the smart pump is to set the motor current limit at different temperatures and speeds while the pipeline and medium are fixed. When the motor reaches the current limit, it will stop automatically, thus ensuring that the pressure in the pipeline does not exceed the upper limit and ensuring the safety of the pipeline. Temperature affects the characteristics of the medium and the pump, and speed affects the back EMF and flow rate of the motor, both of which affect the current value at the same pressure. Therefore, the three parameters of temperature, speed, and current affect each other, and the calibration of the current limit of the smart pump at different temperatures and speeds is particularly critical.

[0004] Since the operating temperature range of the pump is very wide, generally from -10°C to 90°C, and the speed ranges from 500rpm to 5000rpm or even higher. In order to estimate and control the pressure more accurately, the temperature and speed are divided into small segments, and a current limit is calibrated for each segment. In this way, the current limit is queried in the pump program to accurately control the pressure. However, the existing technology uses manual calibration, which is very labor-intensive, cumbersome, and time-consuming. Summary of the invention

[0005] In order to solve the existing technical problems, an embodiment of the present invention provides a calibration system for an intelligent pump, the system comprising a temperature chamber device, a calibration pump arranged in the temperature chamber device, a control device and a collection device connected to the calibration pump, and a computing device connected to the control device, the collection device and the calibration pump respectively;

[0006] The computing device is used to communicate with the control device, the computing device obtains a current calibrated temperature section and a current calibrated speed section corresponding to the current calibrated temperature section, the computing device sends a temperature setting value to the control device based on the current calibrated temperature section, and sends a speed setting value to the control device based on the current calibrated speed section;

[0007] The control device acquires the temperature setting value, and controls the temperature of the temperature box device according to the temperature setting value to control the working temperature of the calibration pump;

[0008] The control device obtains the speed setting value and controls the motor speed of the calibration pump according to the speed setting value;

[0009] When the working state of the calibration pump meets the collection condition, the collection device collects the control current of the calibration pump and sends it to the calculation device.

[0010] The above-mentioned embodiment of the present application provides a calibration system for an intelligent pump, which obtains a temperature setting value in a current calibration temperature section, adjusts the temperature of a temperature box device to adjust the working temperature of the calibration pump, obtains a speed setting value in a current calibration speed section, adjusts the rotation speed of the calibration pump, and when the actual voltage value of the calibration pump reaches the voltage setting value, the acquisition device acquires the control current of the calibration pump and sends it to the computing device, thereby obtaining the control current of the calibration pump corresponding to the current calibration temperature and the current calibration speed section. The present application can automatically calibrate the control current of the calibration pump in each calibration temperature section and each calibration speed section, thereby saving calibration time and simplifying the calibration process.

The computing device 40 communicates with the control device 30, the collection device 50 and the calibration pump 10 respectively, and the communication method includes but is not limited to a wireless or wired network communication method. The control device 30 is connected to the temperature chamber device 20 and the calibration pump respectively, and the collection device 50 is connected to the calibration pump 10 and the computing device 40 respectively. The calibration pump 10 is arranged in the temperature chamber device 20, and the temperature chamber device 20 is used to provide the temperature when calibrating the calibration pump 10, and the calibration pump 10 is the intelligent pump to be calibrated. The control device 30 is used to communicate with the computing device 40 to obtain relevant calibration parameter data, and control the temperature chamber device 20 and the calibration pump 10 according to the calibration parameter data. The computer device 40 is used to configure the calibration parameter data. The acquisition device 50 is used to acquire actual operating parameter data of the calibration pump 10 during operation and send the data to the calculation device 40 . The calculation device 40 adjusts the calibration parameter data according to the actual operating parameter data.

[0019] The computing device 40 may include a computing device (e.g., a desktop computer, a laptop computer, a tablet computer, a handheld computer, a smart speaker, a server, etc.), a mobile phone (e.g., a smart phone, a wireless phone, etc.), a wearable device (e.g., a pair of smart glasses or a smart watch), or a similar device.

The acquisition device 50 may be an acquisition card that acquires analog signals through sensors or other analog signal sources, and then uses an analog-to-digital converter (ADC) to convert these analog signals into digital signals, and finally transmits the digital signals to the computing device 40 for subsequent processing.

[0020] In this embodiment, the system includes:

[0021] The computing device 40 obtains the current calibrated temperature section and the current calibrated speed section corresponding to the current calibrated temperature section, and the computing device 40 sends a temperature setting value to the control device 30 based on the current calibrated temperature section, and sends a speed setting value to the control device 30 based on the current calibrated speed section;

[0022] The control device 30 obtains the temperature setting value, and controls the temperature of the temperature box device 20 according to the temperature setting value to control the working temperature of the calibration pump 10;

[0023] The control device 30 obtains the speed setting value and controls the motor speed of the calibration pump 10 according to the speed setting value;

[0024] When the working state of the calibration pump 10 meets the collection condition, the collection device 50 collects the control current of the calibration pump 10 and sends it to the calculation device 40 .

[0025] In this embodiment, the operating temperature range and motor speed range of the calibration pump 10 are divided into a plurality of small intervals, each temperature interval is used as a calibration temperature section, and each speed interval is used as a calibration speed section. The control current of the calibration pump 10 in each calibration temperature section and each calibration speed section can be calibrated. For the current calibration temperature section and the current calibration speed section, the temperature setting value is adjusted within the range of the current calibration temperature section, and the motor speed is adjusted in the current calibration speed section, so that the working state of the calibration pump 10 meets the acquisition conditions, indicating that the calibration is successful at the current calibration temperature and the current calibration speed section, and the control current of the calibration pump 10 can be collected. In an optional embodiment, the motor phase current of the calibration pump 10 is collected as the control current. According to the above steps, the control current of the calibration pump in each calibration temperature section and each calibration speed section is calibrated.

[0026] In the above embodiment, the temperature setting value is obtained in the current calibration temperature section, the temperature of the temperature box device is adjusted to adjust the working temperature of the calibration pump, and the speed setting value is obtained in the current calibration speed section, and the speed of the calibration pump is adjusted. When the working state of the calibration pump meets the collection conditions, the collection device collects the control current of the calibration pump and sends it to the calculation device, thereby obtaining the control current of the calibration pump corresponding to the current calibration temperature and the current calibration speed section. The present application can automatically calibrate the control current of the calibration pump in each calibration temperature section and each calibration speed section, thereby saving calibration time and simplifying the calibration process.

[0027] In some embodiments, the acquisition device acquires the actual temperature of the calibration pump and sends it to the computing device;

[0028] When the actual temperature does not reach the temperature setting value within a preset time period, the computing device re-acquires the temperature setting value from the current calibrated temperature segment and sends it to the control device, and the control device acquires the temperature setting value re-sent by the computing device.

[0029] During the calibration process, the acquisition device 50 acquires the actual temperature of the temperature sensor in the calibration pump 10 in real time. When the actual temperature does not reach the temperature setting value within the preset time, it indicates that the temperature setting value needs to be reset. The computing device 40 re-acquires the temperature setting value, and the control device 30 resets the temperature of the incubator device 20. In an optional embodiment, the computing device 40 may send the speed setting value to the control device only when the actual temperature reaches the temperature setting value.

[0030] In the above embodiment, during the calibration process, the actual temperature in the calibration pump is monitored in real time. When the actual temperature does not meet the standard, the temperature setting value is reset, thereby improving the calibration speed and calibration accuracy.

[0031] In some embodiments, the calibration device further includes a pressure limiting component and a pressure measuring component.

[0032] The calibration device further comprises a pressure measuring assembly, and the pressure measuring assembly is connected to the acquisition device and the calibration pump;

[0033] The acquisition device acquires the actual voltage value collected by the pressure measuring component, and sends the actual voltage value to the calculation device;

[0034] When the actual voltage value does not reach the voltage setting value, the acquisition device continues to acquire the actual voltage value;

[0035] When the actual pressure value reaches the pressure setting value, the acquisition device acquires the control current of the calibration pump and sends it to the calculation device.

[0036] like Figure 2 As shown, the pressure limiting component 60 is a pressure limiting valve. One end of the pressure limiting component 60 is connected to the calibration pump 10, and the other end is connected to the pressure measuring component 70. The control device 30 adjusts the voltage upper limit of the pipeline connected to the calibration pump 10 through the pressure limiting component 60 and the pressure setting value. The pressure measuring component 70 is connected to the pressure limiting component 60 and the acquisition device 50 respectively. The pressure measuring component 70 is used to test the pressure value in the pipeline, and the actual voltage value collected by the pressure measuring component 70 is collected through the acquisition device 50. When the actual pressure value reaches the pressure setting value, it means that the working state of the calibration pump 10 meets the collection conditions. At this time, the control current of the calibration pump is collected, that is, the control current under the current calibration temperature section and the current calibration speed section is obtained.

[0037] In the above embodiment, the temperature setting value is obtained in the current calibration temperature section, the temperature of the temperature box device is adjusted to adjust the working temperature of the calibration pump, and the speed setting value is obtained in the current calibration speed section, and the speed of the calibration pump is adjusted. When the actual voltage value of the calibration pump reaches the voltage setting value, the acquisition device acquires the control current of the calibration pump and sends it to the calculation device, thereby obtaining the control current of the calibration pump corresponding to the current calibration temperature and the current calibration speed section. The present application can automatically calibrate the control current of the calibration pump in each calibration temperature section and each calibration speed section, thereby saving calibration time and simplifying the calibration process.

[0038] In some embodiments, after the acquisition device acquires the control current of the calibration pump and sends it to the computing device, the calibration pump obtains the control current sent by the computing device and writes the control current into the calibration pump as the upper limit current of the calibration pump.

[0039] In this embodiment, the computing device 40 matches the control current with the corresponding calibrated temperature segment and calibrated speed segment, and sends it to the calibration pump 10. The calibration pump 10 uses the control current as the upper limit current of the corresponding calibrated temperature segment and calibrated speed segment, and writes it into the controller of the calibration pump 10.

[0040] In the above embodiment, after obtaining the control current corresponding to the calibration temperature section and the calibration speed section, the control current is used as the upper limit current of the corresponding calibration temperature section and the calibration speed section and is automatically written into the controller of the calibration pump, thereby saving calibration time and simplifying the calibration process.

[0041] In some embodiments, the calibration device further comprises a pressure limiting component, wherein the pressure limiting component is connected to the control device and the calibration pump;

[0042] The control device acquires the target temperature setting value corresponding to the control current sent by the computing device, and controls the temperature of the thermostat device according to the target temperature setting value;

[0043] When the actual test temperature collected by the collection device reaches the target temperature setting value, the control device obtains the target motor speed setting value sent by the calculation device, and controls the motor speed of the calibration pump according to the target motor speed setting value; and the control device obtains the target pressure limit value sent by the calculation device, and adjusts the upper limit of the pressure in the pipeline connected to the calibration pump according to the target pressure limit value and using the pressure limiting component;

[0044] When the calibration pump operates based on the control current, the target pressure limit value, and the target motor speed setting value, the acquisition device acquires the actual test voltage value in the pipeline and sends it to the calculation device;

[0045] The computing device determines, based on the actual test voltage value, whether the control current can trigger a target pressure limit value corresponding to the control current.

[0046] In this embodiment, after obtaining the control current corresponding to the calibration temperature section and the calibration speed section, it is not certain whether the control current is accurately calibrated, and it is necessary to verify the accuracy of the control current again, that is, whether the target pressure limit corresponding to the control current can be triggered. The target temperature setting value is the temperature value obtained from the calibration temperature section during the verification process, and the target motor speed setting value is the speed value obtained from the calibration speed section during the verification process. During the verification process, the actual test temperature of the calibration pump 10 is continuously collected. When the collected actual test temperature reaches the target temperature setting value, the working parameters of the calibration pump 10 are then set based on the control current, the target temperature setting value, the target motor speed setting value and the target pressure limit. At this time, the actual test voltage value during the verification process is collected through the pressure measuring component 70, and the control current can trigger the target pressure limit corresponding to the control current according to the actual test voltage value. The actual test voltage value is measured by the pressure measuring component and is used to obtain the pressure in the pipeline.

[0047] In an optional embodiment, when the actual test voltage value does not reach the target pressure limit value, the computing device determines that the control current needs to be recalibrated, and restarts the calibration step of the control current;

[0048] When the test actual voltage value reaches the target pressure limit, the computing device determines that the control current can trigger the target pressure limit corresponding to the control current.

[0049] In an optional embodiment, when the actual voltage value of the test does not reach the target pressure limit, the computing device sends a deletion instruction of the control current to the calibration pump, and the calibration pump deletes the control current according to the deletion instruction.

[0050] In this embodiment, the target pressure limit corresponds to the calibration temperature section, the calibration speed section and the control current. When the calibration pump is operating under the control current, the target temperature setting value and the target motor speed setting value, the actual voltage value tested does not reach the target pressure limit, indicating that under the calibration temperature section, the calibration speed section and the control current, the calibration pump 10 fails to trigger the target pressure limit corresponding to the control current, indicating that the set of data needs to be recalibrated and the corresponding control current needs to be deleted from the controller of the calibration pump 10.

[0051] In the above embodiment, after the control current calibration is completed, the calibration pump is controlled within the calibration temperature section and calibration speed section corresponding to the control current, and operates based on the control current, and the actual voltage value tested in this working state is collected in real time. When the actual voltage value tested does not reach the target pressure limit corresponding to the control current, the control current corresponding to the calibration temperature section and calibration speed section is automatically recalibrated, thereby improving the calibration accuracy and simplifying the calibration time.

[0052] In an optional embodiment, when the actual test temperature collected by the collection device does not reach the target temperature setting value, the actual test temperature continues to be collected.

[0053] In the above embodiment, during the verification process, the actual test temperature is dynamically monitored, and when the actual test temperature reaches the target temperature setting value, the subsequent verification process is continued, thereby saving calibration time and improving calibration accuracy.

[0054] In some embodiments, the acquisition device also acquires a feedback speed of the calibration pump when it is working, and the calculation device obtains the feedback speed and adjusts the calibration parameter data according to the feedback speed.

[0055] In this embodiment, the calibration parameter data includes but is not limited to a temperature setting value, a speed setting value, and a pressure setting value. During the calibration process, a pulse width modulation (PWM) signal or a controller area network (CAN) signal of the calibration pump 10 is obtained in real time, and the feedback speed is calculated according to the PWM signal or the CAN signal.

[0056] In this embodiment, the feedback speed of the calibration pump when it is working is obtained in real time, and the calibration parameter data is adjusted according to the feedback speed, thereby improving the calibration accuracy and saving the calibration time.

[0057] In some embodiments, after calibration is completed, each of the control currents corresponds to a calibrated temperature segment and a calibrated speed segment.

[0058] In this embodiment, since the working temperature range and working speed range of the calibration pump are relatively large, and the temperature, speed and current affect each other, the working temperature range is divided into a plurality of calibration temperature segments, and the working speed range is divided into a plurality of calibration speed segments in advance, and the plurality of groups of data formed by each calibration temperature segment and each calibration speed segment are calibrated, so that each group of data corresponds to a control current. Therefore, each control current corresponds to a calibration temperature segment and a calibration speed segment.

[0059] In the above embodiment, multiple groups of data formed by each calibration temperature section and each calibration speed section are calibrated, so that a control current corresponding to each group of data is obtained, and the control current of the calibration pump in each calibration temperature section and each calibration speed section can be automatically calibrated, thereby saving calibration time and simplifying the calibration process.
