[0031] Reference Figures 1 to 3 , an embodiment of the present application provides a detection device 100 for detecting a TTL module 10, the detection device 100 comprising a motor 101, a rotary encoder 102, a control unit 103 and a power supply 104, wherein the rotary encoder 102 is electrically connected between the motor 101 and the TTL module 10 to convert the speed signal of the motor 101 into an electrical signal and transmit it to the TTL module 10 for decoding. The control unit 103 is electrically connected to the motor 101 and the TTL module 10 to control the rotation of the motor 101, the control unit 103 receives the decoded signal sent by the TTL module 10 and compares it with the speed signal of the motor 101. The power supply 104 is electrically connected to the motor 101, the rotary encoder 102 and the control unit 103.
[0032] Specifically, the function of the motor 101 is to imitate the rotation of the fan. The rotary encoder 102 converts the mechanical displacement of the motor 101 into an electrical signal, and transmits the electrical signal to the TTL module 10 for decoding processing. The control unit 103 is electrically connected to the motor 101 and the TTL module 10 to control the rotation of the motor 101 and receive the decoding signal sent by the TTL module 10. When the control unit 103 receives the decoding signal sent by the TTL module 10, it will compare the speed information contained in the decoding signal with the speed signal sent to the motor 101. When the difference between the two is within a reasonable preset range, the TTL module 10 is judged to be in a normal state. Otherwise, the TTL module 10 is judged to be in an abnormal state.
[0033] Therefore, the detection device 100 provided in the embodiment of the present application sends a rotation command to the motor 101 through the control unit 103, simulates the rotation of the fan, and converts the speed signal of the motor 101 into an electrical signal through the rotary encoder 102, and transmits it to the TTL module 10 for decoding. The control unit 103 receives the decoded signal generated by the TTL module 10 and compares it with the speed signal sent to the motor 101, thereby automatically determining the performance of the TTL module 10, thereby improving the operating stability of the fan and reducing the maintenance cost of the fan.
[0034] It should be noted that the rotary encoder 102 converts the mechanical displacement of rotation into corresponding electrical signals through its internal mechanical structure and optoelectronic components. These electrical signals may be pulse signals or code signals, depending on the type and design of the encoder. Rotary encoders 102 include incremental and absolute rotary encoders. Incremental rotary encoders typically output two-phase pulse signals, A and B, with a 90-degree phase difference between the two phases, which are used to measure rotational speed and determine rotational direction. Absolute rotary encoders directly output code signals that correspond to position, such as binary or BCD codes. After receiving the signals from the rotary encoder 102, the TTL module 10 decodes and processes them. For the two-phase pulse signals A and B output by the incremental rotary encoder, the TTL module 10 can measure rotational speed and rotational direction by counting the number of pulses and determining the phase relationship between the two phases. For the code signals output by absolute rotary encoders, the TTL module 10 can directly read and decode the corresponding position information.
[0035] Further, refer to Figure 2 In some embodiments of the present application, the detection device 100 also includes a CAN (Controller Area Network) communication decoding unit 105. The CAN communication decoding unit 105 is electrically connected between the TTL module 10 and the control unit 103. The CAN communication decoding unit 105 converts the decoding signal of the TTL module 10 into a CAN signal, and converts the CAN signal into a serial port signal and transmits it to the control unit 103.
[0036] Specifically, the CAN communication decoding unit 105 is used to parse and interpret CAN bus communication data. In the detection device 100 provided in the embodiment of the present application, the CAN communication decoding unit 105 is electrically connected between the TTL module 10 and the control unit 103. The CAN communication decoding unit 105 converts the decoding signal of the TTL module 10 into a CAN signal, and converts the CAN signal into a serial port signal and transmits it to the control unit 103, thereby realizing remote transmission and monitoring of the signal. Therefore, the user can remotely detect and monitor the TTL module 10.
[0037] Further, refer again to Figure 2 In some embodiments of the present application, the control unit 103 includes an electrically connected touch screen 131 and a single-chip microcomputer (not shown). The touch screen 131 includes a user interaction interface for setting the target speed. The single-chip microcomputer receives instructions sent by the touch screen 131 to control the motor 101 and receives serial port signals transmitted by the CAN communication decoding unit 105.
[0038] That is, the user can input the speed information through the touch screen 131 of the control unit 103, and the single chip microcomputer is used to collect and analyze the information, such as receiving the instructions sent by the touch screen 131 to control the motor 101, and receiving the serial port signal transmitted by the CAN communication decoding unit 105, and comparing it with the speed signal sent to the motor 101, so as to automatically determine the performance of the TTL module 10, thereby improving the ease of use of the detection device 100 and improving the user experience.
[0039] Furthermore, in some embodiments of the present application, the rotation mode of the motor 101 is set to a constant speed mode, a variable speed mode, and a random wind speed mode. The control unit 103 can set the rotation mode of the motor 101 to a variety of fan simulation speed modes, such as constant speed, variable speed, and random wind speed, to meet the different testing requirements of the TTL module, thereby improving the detection accuracy of the TTL module.
[0040] Further, refer to Figure 3 In some embodiments of the present application, the detection device 100 further includes a power management unit 106, which is electrically connected to the power supply 104 to control the output voltage of the power supply 104. For example, the power management unit 106 converts the 220V AC power provided by the power supply 104 into 24V DC power for use by the motor 101, and converts the 220V AC power provided by the power supply 104 into 5V DC power for use by the touch screen 131 and the single-chip microcomputer of the control unit 103. This ensures the normal operation of the motor 101 and the control unit 103, eliminates the need to provide multiple power supplies, and reduces the complexity of the detection device 100.
[0041] Furthermore, in some embodiments of the present application, the power management unit 106 includes a voltage stabilization circuit (not shown), which is electrically connected to the motor 101 , the rotary encoder 102 , the control unit 103 and the power supply 104 .
[0042] Specifically, the voltage stabilization circuit maintains a constant output voltage through the synergistic effect of a negative feedback mechanism and a voltage stabilization element, thereby protecting related components such as the motor 101, the rotary encoder 102, and the control unit 103 from voltage fluctuations, thereby ensuring that the motor 101, the rotary encoder 102, and the control unit 103 can operate stably.
[0043] Furthermore, in some embodiments of the present application, the detection device 100 further includes an alarm unit (not shown), which is electrically connected to the control unit 103 to warn that there is an abnormality in the decoding signal sent by the TTL module 10 .
[0044] As described above, the control unit 103 is electrically connected to the motor 101 and the TTL module 10 to control the rotation of the motor 101 and receive the decoded signal sent by the TTL module 10. After the control unit 103 receives the decoded signal sent by the TTL module 10, it will compare the speed information contained in the decoded signal with the speed signal sent to the motor 101. When the difference between the two is within a reasonable preset range, the TTL module 10 is determined to be in a normal state. Otherwise, the TTL module 10 is determined to be in an abnormal state. Therefore, when there is an abnormality in the decoded signal sent by the TTL module 10, that is, there is a problem with the function of the TTL module, the alarm unit can issue a response alarm signal, so that the user can promptly discover the abnormality of the TTL module.
[0045] Furthermore, in some embodiments of the present application, the detection device 100 further includes a storage unit (not shown), which is electrically connected to the control unit 103 and is used to store the decoded signal sent by the TTL module 10 .
[0046] Specifically, the storage unit is used to store historical data, configuration parameters, and fault records of the TTL module 10 for subsequent data analysis and system maintenance, thereby facilitating accurate determination of the status of the TTL module 10 .
[0047] Furthermore, if Figures 1 to 3 As shown, in some embodiments of the present application, the detection device 100 further includes a housing 107. The housing 107 is a hollow structure, and the motor 101, the rotary encoder 102, the control unit 103, and the power supply 104 are accommodated in the housing 107. The housing 107 is used to accommodate relevant components of the detection device 100, such as the motor 101, the rotary encoder 102, the control unit 103, and the power supply 104, so that the detection device 100 becomes an independent device that is easy for the user to carry.
[0048] Further, refer again to Figure 1 In some embodiments of the present application, the touch screen 131 of the control unit is mounted on the side wall 171 of the housing 107. Therefore, the touch screen 131 of the control unit can be exposed outside the housing 107, so that the user can operate the touch screen 131 to send a rotation instruction to the motor 101 and observe the judgment result of the TTL module 10 from the touch screen 131.
[0049] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
