[0045] For the purpose, technical solutions and advantages of the present application to be more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the present application and not to limit the present application.

[0046] In one embodiment, as shown in Fig. 1, a test method of a sense loop system is provided, comprising the following steps: Figure 1

[0047] Step 102, obtaining the rotor position of the rotating motor as a reference position.

[0048] A certain length of transmitting antenna is installed on the rotor.

[0049] The actual position of the motor rotor can be obtained by using a rotary transformer, and the rotor of the rotary transformer is coaxial with the rotor of the rotating motor. The rotary transformer is a precise angle, position and speed detection device, which is suitable for all occasions using rotary encoders, especially occasions where high-speed and high-vibration rotary encoders cannot work normally.

[0050] The transmitting antenna is installed on the edge of the rotor, i.e., the mover turntable, and the motor driving and power supply part is installed at the center of the mover turntable. In order to prevent the metal material of the rotor from affecting the space magnetic field of the transmitting antenna, high-performance engineering plastic is selected as the transmitting antenna skeleton, and the skeleton design needs to consider reserving a certain distance from the stator turntable. After the transmitting antenna is preliminarily installed and fixed, it is wrapped and fixed or fixed with bolts. During installation, the antennas are symmetrically installed to ensure the dynamic balance of the rotor.

[0051] Step 104, when the transmitting antenna rotates relative to the cross sense loop, the envelope signal of the cross sense loop is obtained, and the position of the carrier generation unit in the cross sense loop is obtained as a test position according to the envelope signal.

[0052] The carrier generation unit includes a transmitting antenna and a signal generation circuit, and the signal generation circuit is used to provide a carrier signal of the sense loop system. The carrier signal is transmitted to the cross sense loop through the transmitting antenna, so as to realize position coupling and detection. The carrier generation unit driving circuit is installed at the end of the rotating shaft, adopts a cylindrical structure and is coaxial with the stator turntable, so as to reduce the effect of centrifugal force as much as possible under high-speed rotation.

[0053] The cross sense loop is laid on the inner wall of the stator of the rotating motor in a plurality of spliced manners, and the gaps between adjacent cross sense loops and the rotor are different. As shown in Fig. 2, the cross sense loop is laid on the inner wall of the stator of the rotating motor in a plurality of spliced manners, and the gaps between adjacent cross sense loops and the rotor are different. Figure 2 ​As shown, a schematic diagram of the gap change between the transmitting antenna on the rotor and the cross-induction loop is provided. For example, the splicing structure of the cross-induction loop and the transmitting antenna are kept within a gap range of 10±5mm. It can be seen from the figure that the gaps between adjacent cross-induction loops and the transmitting antenna are different. When the rotor of the rotating motor drives the transmitting antenna and the induction loop on the stator to make relative motion, as the transmitting antenna rotates, the gap between the transmitting antenna and the corresponding induction loop changes, and the output signal of the induction loop changes. From this, information such as the displacement and velocity of the carrier generation unit can be obtained, and the relative position of the carrier generation unit and the cross-induction loop at different times can be obtained as the test position.

[0054] like Figure 3 The diagram shows the layout of the stator and rotor of a rotating electric motor. As can be seen, the outermost ring structure is the stator, on which cross-induction loops are laid. The inner ring structure is the rotor, which has a rotor sleeve and a transmitting antenna of a certain length. A rotary transformer is also installed inside the rotating electric motor to obtain the rotor's position as a reference position. A position detection module is used to detect the position of the carrier generation unit within the cross-induction loops, which is also the position of the transmitting antenna within the cross-induction loops. The reference position obtained by the acquisition unit and the test position obtained by the position detection module are compared and analyzed.

[0055] Step 106: Test the positioning function of the induction loop system by testing the test position and the reference position.

[0056] like Figure 4 As shown, a schematic diagram of the signal envelope of the induction loop and the position curve of the rotary transformer is provided.

[0057] When a rotary transformer rotates around its axis for one revolution, its output voltage is a sine wave with one cycle, which can be converted to obtain... Figure 4 The position curve of the rotary transformer, i.e., the reference position curve.

[0058] The number of position cycles detected by the cross-induction loop is the number of loop cycles, such as... Figure 4 In the above, the number of periods of the sine wave, i.e., the number of position periods, is 6. Combining this with step 104, which states "multiple interlocking induction loops are laid," one induction loop corresponds to one loop period. Therefore... Figure 4 The cross-loop induction system shown is laid out using a six-span splicing method. The test position is obtained by converting the signal envelope of the induction loop into a position signal.

[0059] Step 108: Test the speed measurement function of the induction loop system based on the waveform of the envelope signal at different rotor speeds.

[0060] like Figure 5As shown, the schematic diagram of the envelope curve of the inductive loop line high / low speed signal and the resolver position curve is provided, and it can be seen that the inductive loop line envelope curve under low speed condition is basically normal when the resolver rotates 2 turns around the shaft, that is, the speed measurement function of the inductive loop line system under low speed condition meets the requirements. Figure 4 Under high speed condition, the inductive loop line envelope curve is distorted. The test of the speed measurement function is mainly to determine whether the envelope signal of the cross inductive loop line is distorted under a relatively high rotor speed. If the distortion occurs, the position error is obtained through conversion. When the position error exceeds the preset proportion of the cross period of the cross inductive loop line, such as 10%, it can be determined that the dynamic response characteristic of the inductive loop line system under high speed condition does not meet the requirements, wherein the cross period refers to the distance between the two cross points of the cross inductive loop line, and the radian corresponding to the cross point is the same as the radian of the emitter antenna installed on the rotor side.

[0061] The test method of the inductive loop line system includes: obtaining the rotor position of the rotating motor as a reference position, wherein a certain length of emitter antenna is installed on the rotor; obtaining the envelope signal of the cross inductive loop line when the emitter antenna rotates relative to the cross inductive loop line, and obtaining the position of the carrier generation unit in the cross inductive loop line as a test position according to the envelope signal, wherein the carrier generation unit includes the emitter antenna, the cross inductive loop line is laid on the inner wall of the stator of the rotating motor in a spliced manner, and the gap between adjacent cross inductive loop lines and the rotor is different. Such laying manner makes the rotor of the rotating motor drive the emitter antenna and the inductive loop line on the stator to move relatively, and as the emitter antenna rotates, the gap between the emitter antenna and the inductive loop line at the corresponding position changes, and the output signal of the inductive loop line changes. Thus, the relative position of the carrier generation unit and the cross inductive loop line at different times can be obtained as the test position, and the test result of the positioning function of the inductive loop line system can be obtained by comparing the reference position and the test position. According to the waveform of the envelope signal under different rotor speeds, the test result of the speed measurement function of the inductive loop line system can be obtained.

[0062] In one embodiment, the test method of the inductive loop line system further includes: setting a short-circuit fault simulation point at a preset position of the cross inductive loop line, setting the switch of the short-circuit fault simulation point, and obtaining the short-circuit fault simulation test result according to the comparison result of the cross inductive loop line signals before and after the emitter antenna passes through the short-circuit fault simulation point.

[0063] As Figure 6As shown, the signal envelope of the inductive loop and the position curve of the rotary transformer are provided during the short-circuit fault simulation test. After the preset short-circuit fault simulation point is set, its rear loop will be bypassed. When the transmitting antenna passes through its rear loop, the signal envelope of the inductive loop cannot be detected. It can be seen that the signal envelope of the inductive loop is normal before the preset short-circuit fault simulation point, and there is no output signal from the inductive loop after the preset short-circuit fault simulation point is set. Thus, the short-circuit fault simulation test result is normal.

[0064] In one embodiment, the testing method for the induction loop system further includes: setting a circuit breaker simulation point at a preset position of the cross-induction loop, setting the switch of the circuit breaker simulation point, and obtaining the circuit breaker simulation test result based on the comparison of the cross-induction loop signals before and after the transmitting antenna passes through the circuit breaker simulation point.

[0065] like Figure 7 As shown, the signal envelope of the induction loop and the position curve of the rotary transformer are provided during the circuit breaker simulation test. After the preset circuit breaker simulation point is set, the loop behind it will have no output at all. Due to the antenna effect, the loop before the circuit breaker simulation point will have a small amplitude induction signal output. Thus, the circuit breaker simulation test result is normal.

[0066] It should be understood that, although Figure 1 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders.
