Figure 2 The wireless transmission module 23 includes a long-distance radio module 232 and an antenna 231. The long-distance radio module 232 is connected to the acceleration test module 21 and the transmitting end of the antenna 231, and is used to transmit the acceleration data of the object under test to the host computer through the transmitting end of the antenna 231.

Among them, the three-axis accelerometer 212 can simultaneously measure the acceleration data of the three axes of the X-axis, the Y-axis and the Z-axis.

[0060] For example, the three-axis accelerometer 212 collects an acceleration signal of 5V from the object under test, and the analog-to-digital converter 213 converts the above 5V acceleration signal into 0100100, then 0100100 is the acceleration data of the object under test, and then the analog-to-digital converter 213 transmits the acceleration data to the micro control unit 211.

[0061] The acceleration test module 21 also includes a temperature sensor 214 for measuring the operating temperature of the acceleration test module 21 . The micro control unit 211 performs temperature compensation on the acceleration data of the object under test according to the operating temperature of the acceleration test module 21 , and transmits the temperature compensated acceleration data to the wireless transmission module 23 .

[0062] Temperature compensation is a technical means mainly used to reduce or eliminate the impact of temperature changes on system or equipment performance. The temperature compensation in this application is to correct the output signal through a certain algorithm to eliminate the impact of temperature changes on the output signal of components.

[0063] The acceleration test module 21 also includes a storage module 215, which is connected to the micro control unit 211 and is used to store the acceleration data of the object under test obtained by the micro control unit 211. The micro control unit 211 obtains the acceleration data of the object under test and stores it in the storage module 215 of the acceleration test module 21; when the micro control unit 211 receives a data reading instruction from the wireless transmission module 23, the micro control unit 211 reads the corresponding acceleration data from the storage module 215 according to the data reading instruction, and then transmits the read acceleration data to the wireless transmission module 23.

[0064] In one embodiment, the microcontroller unit 211 in the acceleration testing device 2 receives the acceleration acquisition instruction from the wireless transmission module 23, the microcontroller unit 211 controls the three-axis accelerometer 212 to acquire the acceleration signal of the object under test, the three-axis accelerometer 212 is connected to the microcontroller unit 211, the three-axis accelerometer 212 acquires the acceleration signal of the object under test and submits it to the microcontroller unit 211; the microcontroller unit 211 sends the acquired acceleration signal to the analog-to-digital converter 213, the analog-to-digital converter 213 converts the obtained acceleration signal into a digital signal to obtain acceleration data and submits it to the microcontroller unit 211; the temperature sensor 214 can measure the working temperature of the acceleration testing device 2, the microcontroller unit 211 performs temperature compensation on the digital signal (acceleration data) obtained after the conversion by the analog-to-digital converter 213 according to the working temperature measured by the temperature sensor 214, that is, the digital signal (acceleration data) obtained after the conversion is corrected, and the corrected acceleration data is transmitted to the microcontroller unit 211.

[0065] The micro control unit 211 stores the finally obtained acceleration data in the storage module 215 of the acceleration testing device 2. When the micro control unit 211 receives the data reading instruction from the wireless transmission module 23, the micro control unit 211 reads the acceleration data corresponding to the data from the storage module 215, and then transmits the read acceleration data to the wireless transmission module 23.

[0067] Figure 3 This is a schematic diagram of the working mode of an acceleration testing device 2 provided in an embodiment of the present application, see Figure 3 The acceleration testing device 2 mainly includes an activation mode, an idle mode and a sleep mode.

[0068] See also Figure 2The long-distance radio module 232 in the apparatus has one end connected to the antenna 231 and the other end connected to the micro control unit 211. The long-distance radio module 232 receives various instructions from the host computer through the receiving end of the antenna 231, and then transmits the instructions of the host computer to the micro control unit 211.

[0069] In one embodiment, the instruction sent by the host computer is a working mode switching instruction, and the long-distance transmission module receives and transmits the working mode switching instruction to the micro control unit 211 through the receiving end of the antenna 231. After receiving the working mode switching instruction, the micro control unit 211 switches the working mode of the acceleration test device 2 according to the working mode switching instruction. Among them, the working modes of the acceleration test device 2 are mainly active mode, idle mode and sleep mode.

[0070] In the activation mode, the acceleration testing device 2 can perform acceleration acquisition operations, and the node status indicator light flashes green at a frequency of once per second.

[0071] In idle mode, the acceleration testing device 2 detects whether a working mode conversion instruction is received in each preset time period, and can be converted to an active mode or a sleep mode. In this mode, the node status indicator light flashes red at a frequency of once per second.

[0072] In sleep mode, the acceleration test device 2 is in a low power consumption state. In this mode, the acceleration test device 2 consumes very low power and will periodically check whether there is an idle instruction. When an idle instruction is received, it will switch to idle mode. In this mode, the node status indicator light flashes blue at a frequency of once per second.

[0073] As a possible implementation method, the host computer sends an activation mode conversion instruction, the long-distance radio module 232 receives the activation mode conversion instruction sent by the host computer through the antenna 231 receiving end, and transmits the instruction to the microcontroller unit 211 of the acceleration test device 2. The microcontroller unit 211 converts the working mode of the acceleration test device 2 from the idle mode to the activation mode according to the received working mode conversion instruction. At this time, the node status indicator light of the acceleration test device 2 flashes green at a frequency of once per second, and the acceleration test device 2 is performing the acceleration acquisition operation.

[0074] As another possible implementation method, the host computer sends an idle mode conversion instruction, the long-distance radio module 232 receives the idle mode conversion instruction sent by the host computer through the antenna 231 receiving end, and transmits the instruction to the microcontroller unit 211 of the acceleration test device 2. The microcontroller unit 211 converts the working mode of the acceleration test device 2 from the active mode or the sleep mode to the idle mode according to the received working mode conversion instruction. At this time, the node status indicator light of the acceleration test device 2 flashes red at a frequency of once per second, and the acceleration test device 2 is in a non-working idle state.

[0075] As another possible implementation method, the host computer sends a sleep mode conversion instruction, the long-distance radio module 232 receives the sleep mode conversion instruction sent by the host computer through the antenna 231 receiving end, and transmits the instruction to the microcontroller unit 211 of the acceleration test device 2, and the microcontroller unit 211 converts the working mode of the acceleration test device 2 from the idle mode to the sleep mode according to the received working mode conversion instruction. At this time, the node status indicator light of the acceleration test device 2 flashes blue at a frequency of once per second, and the acceleration test device 2 is in a low-power sleep state.

[0076] Different working modes are switched through a variety of working mode conversion instructions. In the active mode, the acceleration test device 2 is in a normal working state. In the idle mode, the acceleration test device 2 is in a suspended state. In the sleep mode, the acceleration test device 2 is in an extremely low power sleep state. In this mode, the acceleration test device 2 will turn off the acceleration test function, but still retain related data so as to quickly restore the working state. This method significantly reduces power consumption by turning off the functions of the device in the idle mode and the sleep mode, thereby extending the battery life and the service life of the device. At the same time, it can quickly restore to the active mode through the idle mode, thereby improving the use efficiency of the device.

[0077] In one embodiment, the instruction sent by the host computer is an acquisition mode conversion instruction, and the long-distance transmission module receives and transmits the acquisition mode conversion instruction to the micro control unit 211 through the receiving end of the antenna 231. After receiving the acquisition mode conversion instruction, the micro control unit 211 switches the acquisition mode of the acceleration test device 2 according to the acquisition mode conversion instruction. Among them, the acquisition modes of the acceleration test device 2 are mainly continuous acquisition mode, periodic acquisition mode and response acquisition mode.

[0078] In the continuous acquisition mode, the acceleration test device 2 will continuously perform the acceleration acquisition operation. In the periodic acquisition mode, the microcontroller unit 211 will periodically control the three-axis accelerometer 212 to perform the acceleration acquisition operation according to a preset time interval. The response acquisition mode means that the acceleration test device 2 starts to perform the acceleration acquisition operation due to a certain event triggering it.

[0079] As a possible implementation, the instruction sent by the host computer is a continuous acquisition mode conversion instruction. The long-distance radio module 232 receives the continuous acquisition mode conversion instruction sent by the host computer through the receiving end of the antenna 231, and transmits the instruction to the micro control unit 211 of the acceleration test device 2. The micro control unit 211 controls the acceleration test device 2 to switch to the continuous acquisition mode according to the received continuous acquisition mode conversion instruction. At this time, the micro control unit 211 controls the three-axis accelerometer 212 to continuously perform the acceleration acquisition operation according to the continuous acquisition mode conversion instruction.

[0080] As another possible implementation, the instruction sent by the host computer is a periodic acquisition mode conversion instruction, and the long-distance radio module 232 receives the periodic acquisition mode conversion instruction sent by the host computer through the receiving end of the antenna 231, and transmits the instruction to the micro control unit 211 of the acceleration test device 2. The micro control unit 211 controls the acceleration test device 2 to switch to the periodic acquisition mode according to the received periodic acquisition mode conversion instruction. At this time, the micro control unit 211 controls the three-axis accelerometer 212 to perform an acceleration acquisition operation every certain time period according to the periodic acquisition mode conversion instruction.

[0081] As another possible implementation, the instruction sent by the host computer is a response acquisition mode conversion instruction. The long-distance radio module 232 receives the response acquisition mode conversion instruction sent by the host computer through the antenna 231 receiving end, and transmits the instruction to the microcontroller unit 211 of the acceleration test device 2. The microcontroller unit 211 controls the acceleration test device 2 to switch to the response acquisition mode according to the received response acquisition mode conversion instruction. At this time, the microcontroller unit 211 responsively controls the three-axis accelerometer 212 to perform the acceleration acquisition operation. For example, the acceleration test device 2 is triggered to perform the acceleration acquisition operation by moving the acceleration test device 2. In addition to responding to the moving operation to trigger the acceleration test device 2 to perform the acceleration acquisition operation, the acceleration test device 2 can also be triggered to perform the acceleration acquisition operation in response to the fast moving operation, the device inversion operation, etc., and the embodiment of the present application does not limit this.

[0082] By switching between a variety of different acquisition modes, different acquisition requirements are met and applied to a variety of acceleration test environments, the measurement performance of the acceleration test device 2 is improved while improving the user experience.

[0085] Specifically, the host computer 41 sends an acceleration acquisition instruction to the acceleration test device 10; the acceleration test device 10 receives the acceleration acquisition instruction and performs the acceleration acquisition operation, and the acceleration test device 10 stores the acquired acceleration data in the storage module 215. When receiving the data reading instruction, the acceleration test device 10 reads the acceleration data from the storage module 215 and transmits it to the host computer 41; after receiving the acceleration data transmitted by the acceleration test device 10, the host computer 41 processes it to obtain the final acceleration of the object under test.

[0088] In one embodiment, the digital signal of acceleration is converted into a numerical value of acceleration by using the following formula (1) for calculation:

[0089] g=bits×slope+offset…………………………Formula (1)

[0090] Wherein, g represents the value of acceleration, bits represents the digital signal of acceleration, offset represents the bias, and slope represents the slope.
