BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 is a schematic diagram of a vibration test monitoring system for a lamp according to an embodiment of the present invention;

[0019] Figure 2 The figure is a flow chart of a vibration test monitoring method of a lamp according to an embodiment of the present invention. DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Figure 1 is a schematic diagram of a vibration test monitoring system for a lamp according to an embodiment of the present invention. Figure 1 As shown, the system includes: a vibration test bench 1, an acceleration test device 2, a vibration test bench control box 3, and an industrial PC 4.

[0022] Among them, the vibration test bench 1 is used to perform a vibration test on the test lamp 5 installed thereon; the acceleration test device 2 is connected to the test lamp 5, and the acceleration test device 2 is used to detect the acceleration change of the test lamp 5 when the test lamp 5 is subjected to the vibration test; the vibration test bench control box 3 is connected to the vibration test bench 1, and the vibration test bench control box 3 is used to control the vibration test bench 1; the industrial PC 4 is respectively connected to the acceleration test device 2 and the vibration test bench control box 3, and the industrial PC 4 is used to obtain the acceleration change of the test lamp 5, and send a control signal to the vibration test bench control box 3 according to the acceleration change of the test lamp, so that the vibration test bench control box 3 controls the vibration test bench 1 according to the control signal.

[0023] Furthermore, the industrial PC 4 is specifically used to: determine the acceleration change of the test lamp within a unit time; if the acceleration change of the test lamp within a unit time exceeds a preset value, and the acceleration of the test lamp does not decay within the preset time, a stop signal is sent to the vibration test bench control box, so that the vibration test bench control box controls the vibration test bench to stop working according to the stop signal.

[0024] Specifically, the vibration test bench control box 3 can control the operation and stop of the vibration test bench 1, and the industrial PC 4 can receive the signal of the acceleration test device 2, and can process and analyze the received signal. When the vibration test starts, the acceleration test device continuously monitors the acceleration value of the test lamp 5 during vibration, and transmits it to the industrial PC 4. The industrial PC 4 can judge whether the test lamp 5 is invalid according to the acceleration of the test lamp. The industrial PC 4 recognizes that the acceleration is significantly increased. For example, if the industrial PC 4 judges that the acceleration change of the test lamp in a unit time exceeds the preset value, and the acceleration of the test lamp does not decay within the preset time (for example, 1min), then the test lamp 5 is judged to be vibrated and invalid. If the industrial PC judges that the test lamp 5 is vibrated and invalid, a stop signal is sent to the vibration test bench control box 3. After receiving the stop signal, the vibration test bench control box 3 controls the vibration test bench to stop working. At the same time, the industrial PC 4 saves the acceleration test data of the test lamp 5. For example, the vibration test bench control box 3 can control the vibration test bench 1 to power off to control the vibration test bench 1 to stop working.

[0025] Therefore, the system can stop the test when the lamp fails according to the acceleration change of the experimental lamp, retaining the initial state of the lamp failure, providing a basis for subsequent analysis of the cause of failure, saving vibration resources and reducing unnecessary waste.

[0026] In one embodiment of the present invention, Figure 1 As shown, the test lamp 5 can be installed on the vibration test bench 1 through the vibration test fixture 6. The vibration test fixture 6 is a tool that can fix the test tool on the vibration test bench.

[0027] In one embodiment of the present invention, Figure 1 As shown, the acceleration testing device 2 may include: an acceleration sensor 21 and a signal processing unit 22, wherein the acceleration sensor 21 is used to collect the acceleration signal of the test lamp 5; the signal processing unit 22 is connected to the acceleration sensor 21 through a wire 23, and the signal processing unit 22 is used to provide power to the acceleration sensor 21, and filter and perform analog / digital conversion processing on the acceleration signal collected by the acceleration sensor 21.

[0028] In an embodiment of the present invention, the test lamp comprises an automobile lamp.

[0029] In summary, according to the vibration test monitoring system of the lamp of the embodiment of the present invention, the vibration test is performed on the test lamp installed thereon through the vibration test bench, the acceleration test device detects the acceleration change of the test lamp when the test lamp is subjected to the vibration test, the vibration test bench control box controls the vibration test bench, the industrial PC obtains the acceleration change of the test lamp, and sends a control signal to the vibration test bench control box according to the acceleration change of the test lamp, so that the vibration test bench control box controls the vibration test bench according to the control signal. Therefore, the system can stop the test when the lamp fails according to the acceleration change of the experimental lamp, retain the initial state of the lamp failure, provide a basis for the subsequent analysis of the cause of failure, and save vibration resources and reduce unnecessary waste.
