[0060] In order to keep the following description of the embodiments of the present application clear and concise, the present application omits detailed descriptions of some known functions and known components.

[0061] The embodiment of the present application provides a pressure and temperature measurement and calibration method based on current reconstruction.

[0062] Figure 1 The flowchart of the pressure and temperature measurement calibration method based on current reconstruction in an embodiment of the application is as follows: Figure 1 As shown, a pressure and temperature measurement calibration method based on current reconstruction in an embodiment of the application includes steps S100 to S102:

[0063] S100, collecting a first sequence of modulation currents and a second sequence of modulation currents respectively;

[0064] S101, deconstructing the first sequence of modulation currents to obtain a pressure calibration value;

[0065] S102, deconstructing the second sequence of modulation currents to obtain a temperature calibration value.

[0066] The execution subject performs steps S100 to S102 based on the improved verification and calibration system, such as Figure 2 As shown, the improved verification and calibration system includes:

[0067] The sequence wave module 10 is configured to output a modulated current I to the independent bus BUS according to a set sequence. base ;

[0068] The pressure measuring instrument 11 is configured to superimpose a pressure current I on the independent bus BUS according to the pressure measurement result. P ; Wherein, the pressure current I P is superimposed on the modulation current of the first sequence I base ;

[0069] The temperature measuring instrument 12 is configured to superimpose a temperature current I on the independent bus BUS according to the temperature measurement result. T ; Wherein, the temperature current I T is superimposed on the modulation current of the second sequence I base ;

[0070] Among them, the sequence wave module outputs a blank modulation current in the form of PWM pulses, and different sequences are formed according to the form of PWM pulses. The waves of different sequences constitute a sector form. The pressure measuring instrument forms a pressure current of an analog signal after detecting the pressure, or the temperature measuring instrument forms a temperature current of an analog signal after detecting the pressure, and the analog signal is superimposed on the modulation current of the corresponding sequence. According to the difference in sequence / sector, the analog signals of multiple different instruments and equipment are carried in a time-sharing form on the same modulation current. The subsequent sampling circuit only needs to collect the modulation current, and the number of sampling circuits is not limited by the increase in instruments and equipment.

[0071] Preferably, the sequence wave generation module is configured to output the modulated current in a four-segment wave generation manner.

[0072] Figure 3 It is a schematic diagram of the wave generation mode of the sequence wave generation module, such as Figure 3 As shown, the sequence wave module adopts four-segment wave generation, including 6 sectors. Taking the first sector as an example, if you want to output V ref Voltage needs to be synthesized using adjacent effective vectors V1 and V2. The specific synthesis method is as follows:

[0073]

[0074] T s =T0+T1+T2;

[0075]

[0076] Among them, Ts is the PWM carrier period of the sequence wave module, V0 is the zero vector, V1, V2 are adjacent effective vectors, T0 is the zero vector action time, T1, T2 are adjacent effective vector action time, V ref is the desired output voltage, V dc is the independent bus voltage, and θ is the angle between the output voltage vector and the V1 vector.

[0077] Figure 4 This is a time diagram of the conventional wave generation method, such as Figure 4 As shown, conventional wave will evenly distribute the action time of T1, T2, and T0. In the first sector, and The independent bus current will flow through the capacitor at this moment, and the modulation current can be sampled and reconstructed. or When the current of the independent bus is very short, due to the influence of the dead zone and the sampling bandwidth, it is impossible to sample the current of the independent bus. In addition, T1 or T2 is very short, and it is necessary to divide it into two equal parts. and Not conducive to sampling.

[0078] Therefore, in the preferred embodiment of the application, a four-stage wave-generating method is adopted to concentrate the effective self-effective vector at the beginning, and two new Tz effective vectors are added at the beginning of each wave-generating segment. The current sampling action is completed in these two effective vectors. At the same time, in order not to change the equivalent vector action time, T1 and T2 are readjusted. The calculation formula is as follows:

[0079]

[0080]

[0081] like Figure 5 As shown, the PWM wave is no longer symmetrical about the center, and the effective vector T1 or T2 is concentrated in the middle, and the U-phase current Iu is sampled in the first Tz segment, as shown in Figure 5 ADC1 in the second Tz segment completes the sampling of the W phase current Iw, such as Figure 5 ADC2 in; V phase current Iv = -Iu - Iw. This is the sampling timing of the first sector, and the same applies to other sectors.

[0082] Based on four-segment wave, such as Figure 6 As shown, the process of deconstructing the first sequence of modulation currents in step S101 to obtain the pressure calibration value includes step S200:

[0083] S200 , inserting a pressure current at the beginning of the first sequence, obtaining a first sampling current in a sampling sequence window, and reconstructing a pressure calibration value according to the first sampling current.

[0084] like Figure 6 As shown, the process of deconstructing the temperature current of the second sequence in step S102 to obtain the temperature calibration value includes step S201:

[0085] S201 , inserting a temperature current at the beginning of the second sequence, obtaining a second sampling current in a sampling sequence window, and reconstructing a temperature calibration value according to the second sampling current.

[0086] Among them, Figure 7 As shown, in step S200, a pressure current is inserted at the beginning of the first sequence, and a first sampling current is obtained in a sampling sequence window. The process of reconstructing a pressure calibration value according to the first sampling current includes steps S300 to S302:

[0087] S300, decomposing the pressure current into two effective pressure vectors, and inserting the two effective pressure vectors into the beginning segment of the first sequence;

[0088] S301, completing sampling of a first sampling current during a window period formed by the effective pressure vector;

[0089] S302: reconstruct the first sampled current into a three-phase current, and calculate the effective value of the three-phase current as the pressure calibration value.

[0090] Among them, Figure 7 As shown, in step S201, a temperature current is inserted at the beginning of the second sequence, and a second sampling current is obtained in a sampling sequence window. The process of reconstructing a temperature calibration value according to the second sampling current includes steps S400 to S402:

[0091] S400, decomposing the temperature current into two effective temperature vectors, and inserting the two effective temperature vectors into the beginning segment of the second sequence;

[0092] S401, completing sampling of a second sampling current during a window period formed by the effective temperature vector;

[0093] S402: reconstruct the second sampled current into a three-phase current, and calculate the effective value of the three-phase current as the temperature calibration value.

[0094] In step S300 to step S302, the effective pressure vector is allocated to correspond to V1, V2, the three-phase currents Iu, Iw and Iv are calculated, and the effective values ​​of the three-phase currents Iu, Iw and Iv are used as pressure calibration values.

[0095] Similarly, in step S400 to step S402, the effective temperature vector is assigned to correspond to V1, V2, the three-phase currents Iu, Iw and Iv are calculated, and the effective values ​​of the three-phase currents Iu, Iw and Iv are used as temperature calibration values.

[0096] Preferably, if Figure 6 As shown, the pressure and temperature measurement calibration method based on current reconstruction in the preferred embodiment further includes step S202 and step S203:

[0097] S202, searching for a pressure measurement value corresponding to the pressure calibration value according to a table lookup method;

[0098] S203, searching for a temperature measurement value corresponding to the temperature calibration value according to a table lookup method.

[0099] According to the table lookup method, the corresponding measurement value is determined according to the pre-calibration to obtain accurate pressure and temperature measurement results.
