Technical Field

[0001] The present invention relates to the field of electrical technology, and in particular to a calibration method, device, storage medium and processor for multi-channel synchronous temperature measurement equipment. Background Art

[0002] At present, the method of pre-embedding multiple temperature measuring resistors in the key parts and environment of the motor is adopted to monitor the temperature of the key positions, and to issue an alarm before an over-temperature fault occurs, so as to notify the maintenance personnel to carry out repairs and inspections. However, due to the installation position and the length of the transmission cable of the different motors to be monitored, it is necessary to calibrate multiple temperature measuring circuits in detail to restore the real temperature information. It takes a long time to calibrate each temperature measuring circuit separately, and the multi-channel calibration data also takes up a lot of memory of the temperature measuring equipment.

[0003] The inventors of the present application discovered during the process of implementing the present invention that the above-mentioned problems have not been effectively solved. Summary of the invention

[0008] Determine a first corresponding relationship between the measured voltage Vo and the resistance value Rpt of the temperature measuring component according to the circuit principle of the multi-channel synchronous temperature measuring device; and

[0009] When the voltage values ​​measured in each channel are consistent, the resistance values ​​of the temperature measuring component corresponding to T1_0, T2_0 and a plurality of calibration temperature values ​​are calibrated based on the first corresponding relationship.

[0012] Preferably, T1_0=1.1*T1-0.1*T2, T2_0=1.1*T2-0.1*T1.

[0013] Furthermore, the calibration method of the multi-channel synchronous temperature measurement device also includes:

[0014] If T1_0, T2_0 and any calibration point among the multiple calibration temperature values ​​cannot make the temperature measurement result of each channel consistent, then multiple calibration temperature values ​​are reselected between T1_0 and T2_0 and the calibration is performed again.

[0015] Furthermore, the calibration method of the multi-channel synchronous temperature measurement device also includes:

[0016] If the total error of the temperature measurement results of T1_0, T2_0 and multiple calibration temperature values ​​compared with the theoretical value obtained according to the circuit principle exceeds the preset error range, multiple calibration temperature values ​​are reselected between T1_0 and T2_0 and recalibrated.

[0017] Optionally, the number of the reselected multiple calibrated temperature values ​​is twice the number of the multiple calibrated temperature values ​​before the reselection.

[0018] On the other hand, an embodiment of the present invention provides a calibration device for a multi-channel synchronous temperature measurement device, wherein multiple channels of the multi-channel synchronous temperature measurement device are all measured by temperature measurement components of the same specification, including: a calibration temperature value determination module, a first corresponding relationship determination module and a calibration module,

[0019] Among them, the calibration temperature value determination module determines the temperature measurement range of the multi-channel synchronous temperature measurement equipment, the temperature measurement range is a continuous interval from the lowest measurement temperature T1 to the highest measurement temperature T2, determines the first calibration temperature value T1_0 lower than T1 and the second calibration temperature value T2_0 higher than T2, and determines multiple calibration temperature values ​​between T1_0 and T2_0;

[0030] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0031] The embodiment of the present invention provides a calibration method for a multi-channel synchronous temperature measurement device, wherein multiple temperature measurement channels of the device are all measured by temperature measurement components of the same specification. The implementation process is as follows: Figure 1 As shown, including:

[0032] Step 1: Determine the temperature measurement range of the multi-channel synchronous temperature measurement equipment, which is a continuous interval from the lowest measurement temperature T1 to the highest measurement temperature T2;

[0033] Step 2: Determine a first calibration temperature value T1_0 lower than T1 and a second calibration temperature value T2_0 higher than T2, and determine multiple calibration temperature values ​​between T1_0 and T2_0;

[0034] Step 3: According to the circuit principle of the multi-channel synchronous temperature measurement device, determine the first corresponding relationship between the measured voltage Vo and the resistance value Rpt of the temperature measurement component;

[0035] Step 4: When the voltage values ​​measured in each channel match, the resistance values ​​of the temperature measuring component corresponding to T1_0, T2_0 and multiple calibration temperature values ​​are calibrated based on the first corresponding relationship.

[0036] Specifically, since the multiple temperature measurement channels of the multi-channel synchronous temperature measurement device are all measured by temperature measurement components of the same specifications, the first calibration temperature value T1_0 selected in step 2, which is lower than the lowest measurement temperature T1 of the multi-channel synchronous temperature measurement device, and the second calibration temperature value T2_0, which is higher than the highest measurement temperature T2 of the multi-channel synchronous temperature measurement device, can be the typical calibration temperature values ​​of the temperature measurement components in each channel selected based on experience, or the endpoint calibration temperature values ​​of the continuous interval that makes the temperature-resistance calibration curve conform to the linear relationship, or the maximum and minimum temperature values ​​that the temperature measurement components can measure. In short, technicians can choose to cover as large a calibration range as possible while meeting the design requirements of the multi-channel synchronous temperature measurement device.

[0037] In this embodiment, T1_0=T1-(T2-T1)*0.1=1.1*T1-0.1*T2, T2_0=T2+(T2-T1)*0.1=1.1*T2–0.1*T1, that is, the two end points [T1_0, T2_0] of the calibration interval set in step 2 make the calibration interval cover 120% of the design working range of the multi-channel synchronous temperature measurement device. More specifically, the temperature measurement range of each temperature measurement channel of the multi-channel synchronous temperature measurement device is a continuous interval between T1_0 and T2_0, therefore, in step 2, multiple calibration temperature values ​​can be equally spaced between T1_0 and T2_0, or selected by interpolation or other methods.

[0038] Specifically, in this embodiment, a temperature measurement circuit of the multi-channel synchronous temperature measurement device adopts Figure 2 The temperature is measured by the bridge method shown in the figure. Among them, Rpt is the PT100 temperature measuring component, and its equivalent resistance is a variable resistor that changes according to the ambient temperature. Different temperatures correspond to different resistance values, and the relationship between the two is the inherent relationship of the PT100 component itself. Figure 2 As shown, a reference voltage Vref loaded on one diagonal of the bridge is 3.6V. Different ambient temperatures will output different output voltages Vo through the bridge. The current ambient temperature can be determined by collecting the current output voltage.

[0039] It should be noted that due to fluctuations in external cables or external interference signals, the output voltage signal may fluctuate and change. Figure 2 The circuit includes filter circuits Z6 and Z7, which perform filtering processing on the input and output parts to filter out external interference signals, so that the output voltage corresponding to the temperature measurement signal is more stable and accurate.

[0040] according to Figure 2 For the designed circuit, the theoretical relationship between the output voltage Vo and the PT100 resistance value Rpt, that is, the first corresponding relationship mentioned in step 3, is the following calculation formula: Vo = 0.0107716Rpt + 2.80572.

[0041] It should also be noted that, in order to avoid errors caused by inconsistencies in the temperature measurement circuits, each circuit usually uses circuits of the same specifications. That is, in this embodiment, the relationship between the output voltage Vo and the PT100 resistance value Rpt in other temperature measurement circuits should also theoretically conform to the calculation formula of the first corresponding relationship mentioned above.

[0042] Because the filter circuits Z6 and Z7 only affect the change process of the output voltage Vo, they will not have any effect on the ratio of the PT100 resistance value to the output voltage at different ambient temperatures. Considering the delay caused by the filter circuits Z6 and Z7, in step 4, the software is used to continuously measure within 10ms until the change of the output voltage Vo is less than 1% / ms. It is considered that this measurement has stabilized. The PT100 resistance value corresponding to the current measured voltage can be determined according to the first corresponding relationship obtained in step 3, and the PT100 resistance value and the current ambient temperature value are calibrated accordingly.

[0043] Compared with the prior art, the technical advantages of this embodiment are:

[0044] 1. Covering 120% of the design working range of multi-channel synchronous temperature measurement equipment;

[0045] 2. A method for synchronous calibration of multiple channels is proposed, which saves the workload of calibrating each channel separately and reduces the storage space occupied by recording calibration data of multiple channels separately;

[0046] 3. Perform unified calibration when the monitoring data of multiple channels are consistent to ensure that the overall error meets the preset standard and reduce measurement errors.

[0047] In order to further reduce the measurement error, in some embodiments, the following steps are also included:

[0048] Step 5: If T1_0, T2_0 and any calibration point among the multiple calibration temperature values ​​cannot make the temperature measurement result of each channel consistent, then reselect multiple calibration temperature values ​​between T1_0 and T2_0 and recalibrate; or

[0049] Step 6: If the total error of the temperature measurement results of T1_0, T2_0 and multiple calibration temperature values ​​compared with the theoretical value obtained according to the circuit principle exceeds the preset error range, multiple calibration temperature values ​​are reselected between T1_0 and T2_0 and recalibrated.

[0050] Specifically, in step 5, if the deviation between the actual measurement value and the theoretical value of any calibration point is greater than 1°C, it means that there is a large deviation in the measurement environment or the measuring instrument, the connection of the measuring cable, etc., then this calibration is invalid and all calibrations are performed again. In step 6, the error value between the actual temperature and the theoretical temperature of each calibration point is recorded, and the error values ​​are added to obtain the overall statistical error. If the overall statistical error is less than (T2-T1)*0.01, this calibration passes. Otherwise, the calibration point needs to be re-determined.

[0051] Furthermore, when recalibrating, select twice the calibration points of the previous calibration and recalibrate the newly selected calibration points. For example, if the factory default 10 calibration points of the multi-channel synchronous temperature measurement device cannot pass the calibration, then select 20 calibration points at equal intervals between the lowest temperature 1.1*T1-0.1*T2 and the highest temperature 1.1*T2–0.1*T1, and restart the calibration until the overall statistical error of all calibration points is less than (T2-T1)*0.01, complete the calibration and save the calibration records to the specified storage device.

[0055] In some embodiments, the calibration module is further configured as follows: if T1_0, T2_0, and any calibration point among the multiple calibration temperature values ​​cannot make the temperature measurement result of each channel consistent, then reselect multiple calibration temperature values ​​between T1_0 and T2_0, and recalibrate; or, if the total error of the temperature measurement results of T1_0, T2_0, and the multiple calibration temperature values ​​compared to the theoretical value obtained according to the circuit principle exceeds a preset error range, then reselect multiple calibration temperature values ​​between T1_0 and T2_0, and recalibrate.
