[0002] In the past, the detection accuracy of different sensors such as acceleration, angular velocity and attitude was not high, and after production, the product was not subjected to large-scale performance detection. However, with the increasing number of customers in the domestic high-precision industry such as unmanned driving and robot manufacturing, the requirements are becoming higher and higher when using different types of attitude sensors, angle sensors, acceleration sensors and other various types of sensors. The traditional test method is sampling detection, that is, an environment bin (used to simulate or create different environment types such as high and low temperature conditions) is set up; after production, the workpiece is sampled and placed in the environment bin, and whether the test data meets the requirements is tested by power-on, and if it meets the requirements, the test is ended. That is, the past test method cannot achieve fine detection for a large number of performance detection.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a sensing state detection device and a sensor detection method based on environmental simulation.

[0035] Example 1: Please refer to Figures 1-4 A sensing state detection device includes a high and low temperature chamber 1 and an environmental chamber 2 disposed on the high and low temperature chamber 1. A roller 3 is disposed inside the environmental chamber 2. Base shafts 4 are installed on both sides of the roller 3. The base shafts 4 are rotatably connected to the side wall of the environmental chamber 2. Multiple mounting plates 5 arranged in a ring array are detachably mounted on the roller 3. The mounting plates 5 are also connected to the roller 3 through magnetic quick-connect interfaces 6. Multiple evenly distributed assembly slots 7 are provided on the mounting plates 5. The assembly slots 7 are used to install sensors. A main motor 8 is fixed outside the high and low temperature chamber 1. The main motor 8 is used to drive the roller 3 to rotate.

[0036] Before testing, multiple sensors are simultaneously mounted on the mounting plate 5 through multiple mounting sockets 7, and multiple mounting plates 5 can also be simultaneously mounted on the roller 3 to achieve batch testing.

[0037] During testing, the environmental chamber 2 simulates a specific temperature test environment, while the main motor 8 operates, forcing the roller 3 to rotate, thereby adjusting the angle and orientation of the sensor within the environmental chamber 2.

[0038] The structure of the magnetic quick-connect interface 6 is existing technology. It mainly includes a male plug on the mounting plate 5 and a female plug on the roller 3. The assembly port 7 can aggregate the test data corresponding to each sensor and finally aggregate them into a communication bus through the magnetic quick-connect interface 6, and finally transmit them to the computer through the external wiring harness.

[0039] In use, multiple sensors are first plugged into the mounting sockets 7 on the mounting plate 5. Then, each mounting plate 5 is installed on the roller 3. After that, the high and low temperature chamber 1 is started. The environmental chamber 2 can be set to different temperature environments according to the temperature requirements of the workpiece to be tested, so that multiple sensors can be detected at the same time. When necessary, the main motor 8 is started. When the main motor 8 is running, it drives the roller 3 to rotate. When the roller 3 rotates, it drives multiple mounting plates 5 and sensors to rotate, thus providing different angles and postures for a batch of sensors.

[0040] This device enables batch installation and testing of workpieces, and facilitates the transmission and aggregation of test data. It solves the problem of requiring separate wiring for each workpiece during individual testing, thus reducing the use of wiring harnesses and the complexity of external wiring for the testing equipment. Furthermore, by using the main motor 8 to drive the roller 3 to rotate, which in turn drives the mounting plate 5 to rotate, different angles and orientations can be created for the sensor under test, enabling multi-angle or linear testing. The magnetic quick-connect connector further reduces the use of wiring harnesses, thereby reducing the complexity of external wiring for the testing equipment. The environmental chamber 2 needs to simulate extreme high or low temperatures. External wiring is prone to damage due to rapid temperature changes and large temperature differences. This fixed communication interface method reduces the use of wiring and avoids the problem of easy damage to wiring in the environmental chamber 2.

[0041] Example 2: See Figures 4-8 Unlike the above embodiments, the roller 3 includes a spindle 31, the axis of which coincides with that of the base shaft 4. Two base shafts 4 are respectively installed at both ends of the spindle 31. Two symmetrically distributed circular plates 32 are fixed on the spindle 31. Multiple radially distributed guide rails 33 are installed on the opposite side of the two circular plates 32. The mounting plate 5 is slidably installed in the guide rail 33. The outer edge of the mounting plate 5 is engaged with the guide rail 33. The inner edge of the mounting plate 5 is connected to the spindle 31 through a magnetic quick-connect interface 6. A slot 34 is provided at the end of the guide rail 33 away from the spindle 31. A sliding groove 35 is provided at the outer corner of the mounting plate 5. A locking block 36 is slidably connected in the sliding groove 35. One end of the locking block 36 is inserted into the slot 34. A push spring 37 is fixed between the other end of the locking block 36 and the end of the sliding groove 35.

[0042] In the installed state, the locking block 36 is inserted into the locking slot 34. When removing the mounting plate 5, the locking block 36 is pushed to disengage from the locking slot 34, and the push spring 37 is compressed. Then, the mounting plate 5 slides outward along the slide groove 35. When the mounting plate 5 slides outward, the magnetic plug interface is disconnected, and finally the entire mounting plate 5 is disengaged from the slide groove 35. Similarly, when reinstalling, the mounting plate 5 is first inserted along the locking slot 34, and then the locking block 36 is pushed to insert the locking block 36 into the locking slot 34. At this time, the magnetic plug interface is reconnected.

[0043] By setting up the slide 35, the slot 34, the spring and the block 36, it is easy to assemble the mounting plate 5 and disassemble it quickly and conveniently, which is conducive to rapid loading and unloading during testing and improves testing efficiency.

[0044] Example 3, see Figures 4-8 Unlike the above embodiments, the high and low temperature chamber 1 has a support frame 9 fixed on its outer wall, the main motor 8 is fixed on the support frame 9, and the output shaft of the main motor 8 is connected to one of the base shafts 4 through a slip ring 10.

[0045] When the main motor 8 is running, it drives the base shaft 4 to rotate, and the base shaft 4 drives the entire drum 3 to rotate, thereby adjusting the angle of the mounting plate 5 on the drum 3, which is beneficial to changing the angle of the sensor. The slip ring 10 can realize the transmission of electrical signals when the drum 3 rotates.

[0046] Example 4, see Figures 4-8 Unlike the above embodiments, the mandrel 31 has a groove 38 at its end, and four notches 39 are provided on the edge of the groove 38. One end of the base shaft 4 extends into the groove 38 and has a cross groove 312. An electromagnetic push rod 310 is also fixed inside the groove 38. A cross tenon block 311 is fixed at the output end of the electromagnetic push rod 310. The cross tenon block 311 engages with the cross groove 312. The four ends of the cross tenon block 311 extend out of the mandrel 31 through the four notches 39.

[0047] When the main motor 8 is running, it drives the base shaft 4 to rotate. When the base shaft 4 rotates, it drives the tenon block 311 to rotate through the cross groove 312. When the tenon block 311 rotates, it drives the side wall of the recess 39, which in turn drives the spindle 31 to rotate. When the spindle 31 rotates, it drives multiple mounting plates 5 to rotate.

[0048] Example 5, see Figures 4-8Unlike the above embodiments, the base shaft 4 is also fixed with a plurality of radially distributed return springs 313 at one end inside the groove 38. The outer end of the return spring 313 is fixedly connected to the inner wall of the groove 38. The end of the spindle 31 is movably sleeved with a ring 314. The ring 314 is fixedly connected to the end of the tenon block 311. The environmental chamber 2 is also equipped with drive components on both sides. The drive components are used to drive the roller 3 to vibrate. The drive components include an auxiliary motor 11 fixed to the inner wall of the environmental chamber 2. The output shaft of the auxiliary motor 11 is fixed with a cam 12. The cam 12 is located on the outer side of the end of the spindle 31.

[0049] In the initial state, the cam 12 and the ring 314 on the spindle 31 are staggered. During use, the electromagnetic push rod 310 is activated, retracting to move the tenon block 311. The tenon block 311 moves along the notch 39 and disengages from the cross groove 312. The movement of the tenon block 311 also moves the ring 314, aligning it with the cam 12. At this point, when the base shaft 4 rotates, it drives the spindle 31 to rotate via multiple return springs 313, still able to drive the entire roller 3 to rotate. When the auxiliary motor 11 is started, it drives the cam 12 to rotate. When the cam 12 rotates, it intermittently pushes the ring 314. When the ring 314 moves, it drives the spindle 31 to rotate. When the spindle 31 moves, it compresses the reset spring 313. After the reset spring 313 recovers, it drives the spindle 31 to reset. This can drive multiple sensors to vibrate. When the main motor 8 and the auxiliary motor 11 start synchronously, the collar can both rotate and move under the action of the spring and the cam 12, so that the sensor can also be tested in an irregular vibration environment.

[0050] By adjusting the positions of the tenon block 311 and the ring 314, and then intermittently pushing the spindle 31 by the rotating cam 12, it is beneficial to drive the sleeve and sensor to vibrate, which can simulate the vibration environment and thus detect the stability of the sensor under the vibration environment. On this basis, the main motor 8 is started to drive the sleeve and sensor to rotate, which makes the vibration more chaotic and complex, thereby simulating various chaotic and complex vibration environments that will be encountered in future actual work, more realistically simulating the vibration environment faced by the sensor in actual work, and making it more adaptable.

[0051] Example 6, see Figures 9-11Unlike the above embodiments, the high and low temperature chamber 1 is further provided with a control chamber 13. The control chamber 13 contains a humidification component 14 for increasing the humidity inside the environmental chamber 2. The humidification component 14 includes a water tank 141, with a mounting block 142 fixed to the bottom of the water tank 141. An atomizer 143 is installed inside the mounting block 142. A water inlet channel 144 is provided on the mounting block 142, extending from the top of the mounting block 142 to the bottom of the atomizer 143. An output pipe 145 is fixed on the mounting block 142. The output tube 145 extends to the top of the atomizer 143, and the other end of the output tube 145 extends into the environmental chamber 2. The control chamber 13 is also equipped with a drying component 15 for reducing the humidity inside the environmental chamber 2. The drying component 15 includes an air pump 151 fixed in the control chamber 13. An air inlet pipe 152 is fixed to the air inlet end of the air pump 151, and the air inlet pipe 152 extends into the environmental chamber 2. An air drying filter 153 is fixed to the exhaust end of the air pump 151, and an exhaust pipe 154 is fixed to the air drying filter 153, and the exhaust pipe 154 extends into the environmental chamber 2.

[0052] Among them, the atomizer 143 is existing technology. The sensor detection also includes detection in a certain humidity environment. At this time, water is injected into the water tank 141. The water flows through the water inlet channel and contacts the atomizer 143. The atomizer 143 is activated to atomize the water flow. The water then enters the environmental chamber 2 through the output pipe 145, thereby increasing the humidity in the environmental chamber 2. When it is necessary to reduce the humidity in the environmental chamber 2, the air pump 151 is activated. The air pump 151 draws in the gas in the environmental chamber 2. The gas is dried when it passes through the air drying filter 153, and then is discharged back into the environmental chamber 2 through the exhaust pipe 154.

[0053] By setting up the humidification component 14 and the drying component 15, it is beneficial to adjust the humidity in the environmental chamber 2, which can be used to detect the stability of the sensor under specific humidity conditions, thus enriching the detection function of the device.
