[0025] The emergence of shared bicycles not only meets the needs of short-distance travel, but also helps solve the problems of traffic congestion and environmental pollution. Most of the central controllers of shared bicycles have vibration detection functions, which can determine whether the shared bicycle is in motion through the vibration detection results, thereby avoiding accidental locking incidents.
[0026] In traditional technologies, most of them stress test the vibration detection function of the central controller of shared bicycles through manual riding.
[0027] However, the stress testing results obtained in this way not only have poor reliability and accuracy, but also have high costs, which in turn makes the stress testing work efficiency low.
[0028] In view of this, the present application provides a stress testing device which can improve the reliability and accuracy of stress testing results and has low cost, thereby effectively improving the work efficiency of stress testing.
[0029] In an exemplary embodiment, Figure 1 As shown, a stress testing device 100 is provided, which includes a vibration table 101, a vibrator 102, a DC motor driver 103 and a host computer 104. The host computer 104 is connected to the DC motor driver 103 to send a first control instruction to the DC motor driver 103; the DC motor driver 103 is connected to the vibrator 102 to drive the vibrator 102 to vibrate when receiving the first control instruction; the vibrator 102 is set on the vibration table 101 to drive the central controller 105 to be tested placed on the vibration table 101 to vibrate.
[0030] Optionally, the vibration table 101 refers to a device that can provide vibration and provide a working plane for installing equipment.
[0031] Optionally, the vibrator 102 refers to a device in which a brushless or brushed motor drives an eccentric wheel to provide a vibration source.
[0032] Optionally, the DC motor driver 103 may be a brushed DC motor driver or a brushless DC motor driver.
[0033] Optionally, the host computer 104 refers to a computer or a single-chip microcomputer that can directly send operation instructions, generally providing a user operation interaction interface and displaying feedback data to the user.
[0034] In one possible implementation, the user can place the central controller 105 to be tested on the vibration table 101, and input vibration parameters based on the upper computer 104. The upper computer 104 generates a first control instruction based on the vibration parameters, and sends the first control instruction to the DC motor driver 103, so that the DC motor driver 103 drives the vibrator 102 to vibrate based on the first control instruction, so that the central controller 105 to be tested on the vibration table 101 is in a vibration environment. Since a vibration threshold is set in the central controller 105 to be tested, if the vibration of the vibration environment in which the central controller 105 to be tested is located is greater than the vibration threshold, the central controller 105 to be tested will consider that it is currently in a motion state. If the vibration of the vibration environment in which the central controller 105 to be tested is located is less than the vibration threshold, the central controller 105 to be tested will consider that it is currently in a non-motion state. Therefore, the vibration environment in which the central controller 105 to be tested is located can be changed by changing the input vibration parameters to achieve stress testing of the central controller 105 to be tested.
[0035] The above-mentioned stress testing device includes a vibration table, a vibrator, a DC motor driver and a host computer, a vibration table, a vibrator, a DC motor driver and a host computer; the host computer is connected to the DC motor driver to send a first control instruction to the DC motor driver; the DC motor driver is connected to the vibrator to drive the vibrator to vibrate when receiving the first control instruction; the vibrator is arranged on the vibration table to drive the central controller to be tested placed on the vibration table to vibrate. The stress testing device provided in the present application only needs to place the central controller to be tested on the vibration table, and the host computer can send a first control instruction to the DC motor driver, so that the DC motor driver drives the vibrator to vibrate based on the first control instruction, and then perform stress testing on the central controller to be tested. The stress testing device provided in the present application can realize automatic stress testing of the central controller to be tested, and there is no need to perform stress testing on the central controller to be tested manually, which not only improves the reliability and accuracy of the stress testing results, but also reduces the labor cost, thereby effectively improving the work efficiency of the stress testing.
[0036] In an exemplary embodiment, Figure 1 As shown, the vibration table 101 includes a vibration table surface 1011 and a vibration table frame 1012 that can prevent the central controller 105 to be tested. The vibration table surface 1011 and the vibration table frame 1012 are connected, and the vibration table surface 1011 is provided with the vibrator 102.
[0037] In one possible implementation, the vibration table frame 1012 is connected to the vibration table surface 1011 for supporting the vibration table surface, and the vibrator 102 is arranged on the vibration table surface 1011. When the user places the central controller 105 to be tested on the vibration table surface 1011 and inputs vibration parameters based on the host computer 104, the host computer 104 generates a first control instruction based on the vibration parameters, and sends the first control instruction to the DC motor driver 103, so that the DC motor driver 103 drives the vibrator 102 to vibrate based on the first control instruction, so that the central controller 105 to be tested on the vibration table surface 1011 is in a vibration environment.
[0038] In an exemplary embodiment, Figure 2 As shown, the vibration table 1011 includes a bearing surface 201 , and the bearing surface 201 is provided with a bracket 2011 that can fix the central controller 105 to be tested.
[0039] Optionally, the bracket 2011 may be a bracket customized based on the vibration table 1011 and the central controller 105 to be tested.
[0040] In one possible implementation, after the host computer 104 sends the first control instruction to the DC motor driver 103, the DC motor driver 103 will drive the vibrator 102 to vibrate based on the first control instruction to drive the vibration table 1011 to vibrate. Therefore, it is necessary to set a bracket 2011 on the vibration table 1011 to fix the central controller 105 to be tested placed on the vibration table 1011 to avoid large vibration of the vibration table 1011, which causes the central controller 105 to be tested to separate from the vibration table 1011, or the vibration of the vibration table 1011 causes the central controller 105 to be tested to vibrate itself, thereby affecting the stress test result.
[0041] In an exemplary embodiment, Figure 2 As shown, the vibration table 1011 also includes a supporting surface 202 opposite to the bearing surface 201 , and the supporting surface 202 is provided with a shock absorbing spring 2021 , one end of the shock absorbing spring 2021 is connected to the supporting surface 202 of the vibration table 1011 , and the other end is connected to the vibration table frame 1012 .
[0042] In an exemplary embodiment, the shock-absorbing spring 2021 may include a first shock-absorbing spring, a second shock-absorbing spring, a third shock-absorbing spring and a fourth shock-absorbing spring, and one end of the first shock-absorbing spring, the second shock-absorbing spring, the third shock-absorbing spring and the fourth shock-absorbing spring is connected to the supporting surface of the vibration table, and the other end is connected to the vibration table frame.
[0043] In a possible implementation, the vibration table 1011 may be rectangular, and the support surface 202 of the vibration table 1011 may be fixed on the vibration table frame 1012 by means of a first shock absorbing spring, a second shock absorbing spring, a third shock absorbing spring, and a fourth shock absorbing spring.
[0044] In an exemplary embodiment, Figure 2 As shown, the vibrator 102 includes a first vibrator 1021, which is fixedly disposed on the support surface 202. The first vibrator 1021 is connected to the DC motor driver, and driven by the DC motor driver to drive the vibration table 1011 to vibrate in the horizontal axis direction.
[0045] In an exemplary embodiment, Figure 2 As shown, the vibrator 102 further includes a second vibrator 1022 , which is fixedly disposed on the support surface 202 . The second vibrator 1022 is connected to the DC motor driver to drive the vibration table 1011 to vibrate in the longitudinal direction under the drive of the DC motor driver.
[0046] In an optional embodiment of the present application, the first vibrator 1021 can be fixedly disposed on the support surface 202X axis of the vibration table 1011 by a first bracket, and the second vibrator 1022 can be fixedly disposed on the support surface 202Y axis of the vibration table 1011 by a second bracket.
[0047] In an optional embodiment of the present application, the first vibrator 1021 and the second vibrator 1022 are connected to the DC motor driver via a first cable and a second cable respectively.
[0048] In one possible implementation, the user can place the central controller to be tested on the vibration table 101, and based on the vibration parameters input by the upper computer, the upper computer generates a first control instruction based on the vibration parameters, and sends the first control instruction to the DC motor driver, so that the DC motor driver drives the first vibrator 1021 and the second vibrator 1022 to vibrate based on the first control instruction, so as to drive the vibration table surface 1011 to vibrate in the horizontal and vertical axis directions respectively.
[0049] In an exemplary embodiment, Figure 3As shown, the device 100 further includes an acceleration sensor 106 , which is disposed on the bearing surface 201 of the vibration table 1011 to collect vibration data of the vibration table 1011 .
[0050] In an exemplary embodiment, the acceleration sensor 106 is connected to the host computer (not shown in the figure) to transmit the vibration data to the host computer, and when the host computer determines based on the vibration data that the actual vibration of the vibration table 1011 is inconsistent with the target vibration, the second control instruction is sent to the DC motor driver so that the DC motor driver drives the vibrator to vibrate based on the second control instruction, and the target vibration is the vibration indicated by the first control instruction.
[0051] In an optional embodiment of the present application, the acceleration sensor is connected to the host computer via a third cable.
[0052] Optionally, the acceleration sensor 106 may be a six-axis sensor, which refers to a device that can detect acceleration and angular velocity of the XYZ axes.
[0053] In one possible implementation, after the vibration table starts to vibrate driven by the first vibrator 1021 and the second vibrator 1022, the acceleration sensor 106 transmits the collected vibration data of the vibration table 1011 to the host computer 104. The host computer 104 determines whether the actual vibration of the vibration table 1011 is consistent with the vibration indicated by the first control instruction based on the vibration data. If not, the host computer 104 sends a second control instruction to the DC motor driver 103, so that the DC motor driver 103 drives the first vibrator 1021 and the second vibrator 1022 to vibrate based on the second control instruction. For example, if the actual vibration is greater than the vibration indicated by the first control instruction, the second control instruction may be an instruction to reduce the vibration. If the actual vibration is less than the vibration indicated by the first control instruction, the second control instruction may be an instruction to increase the vibration. In this way, the inconsistency between the actual vibration of the vibration table 1011 and the vibration indicated by the first control instruction can be avoided, resulting in an error in the stress test result of the central controller 105 to be tested.
[0054] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the present application. It should be noted that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
