[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0022] This application provides a rain testing system that solves the technical problem that if a product fails a rain test, the device continues to expose it to rain, which can damage product components and increase maintenance costs.

[0023] See Figure 1 As shown in the figure, this application provides a rain testing system, which includes: a water tank 1, a water trough 4, and a controller 7. The water tank 1 is equipped with a submersible pump 2, and a relay 3 is provided on the outside of the water tank 1. The relay 3 is electrically connected to the submersible pump 2. The water trough 4 is located above the water tank 1, and the water tank 1 is connected to the water trough 4. The water trough 4 is equipped with a rain nozzle 5, and the water trough 4 has a mounting position for the device under test. The rain nozzle 5 faces the mounting position for the device under test, and the rain nozzle 5 is connected to the submersible pump 2 through a water pipe 6. The controller 7 is electrically connected to the relay 3, and the controller 7 is used to control the relay 3 to disconnect the power supply to the submersible pump 2 when an abnormality is detected in the device under test 8.

[0024] In this embodiment, the water tank 4 can be placed on the water tank 1 or supported above the water tank 1 by a support member. The outer shell of the water tank 1 can be cylindrical or cuboid, and the water tank 4 can be cuboid or other shapes. The device under test mounting position is used to install the device under test 8. The device under test 8 is located below the rain nozzle 5. Water is injected into the water tank 1 by filling the water tank 4. When the submersible pump 2 is powered on, the water in the water tank 1 enters the rain nozzle 5 through the water pipe 6 under the action of the submersible pump 2. The submersible pump 2 continuously pumps water, and at the same time, the rain nozzle 5 continuously sprays water, so that the device under test 8 can be tested under simulated rain conditions. The height of the rain nozzle 5 is lower than the height of the water tank 4 to ensure that all the water sprayed by the rain nozzle 5 enters the interior of the water tank 4. Tank 4 collects the water sprayed by the rain nozzles 5, and the collected water flows into the water tank 1, realizing the water in the water tank 1 being recycled between the water tank 1 and the tank 4. The relay 3 is electrically connected to the power supply of the submersible pump 2. In an exemplary manner, when the device under test 8 is normal, the controller 7 interacts with the device under test 8 at preset time intervals. The preset time can be set to 1 minute. If the device under test 8 can interact with the controller 7 at the preset time, then the device under test 8 is normal and the rain system is tested. When the device under test 8 has no signal, the controller 7 identifies the device under test 8 as abnormal. The controller 7 sends a command to the relay 3 and controls the relay 3 to disconnect the power supply of the submersible pump 2, so that the rain test system stops in time, avoiding damage to the components of the device under test 8 due to continuous rain and reducing maintenance costs.

[0025] This embodiment solves the technical problem in related technologies where, when a product fails a rain test, the device continues to rain, causing damage to product components and increasing maintenance costs. This is achieved by installing a relay 3 electrically connected to the submersible pump 2 on the outside of the water tank 1 and a rain nozzle 5 connected to the submersible pump 2 on the water tank 4. When the controller 7 detects an abnormality in the device under test 8, the controller 7 controls the relay 3 to disconnect the power supply to the submersible pump 2, causing the rain test system to stop in time.

[0026] Further, see Figure 1 As shown, in some embodiments, the controller 7 has a device under test (DUT) electrical interface, which is used to electrically connect to the DUT 8 via a first network cable.

[0027] In this embodiment, the controller 7 can be configured as a PC or other control device. The PC has an electrical interface for the device under test (DUT), and the DUT electrical interface connects the PC to the DUT 8 via the first network cable, allowing the PC to receive signals from the DUT 8 through the first network cable. In other embodiments, the PC can be signal-connected to the DUT 8.

[0028] Further, see Figure 1 As shown, in some embodiments, the relay 3 has a timing module, which is used to disconnect the power supply to the submersible pump 2 when the submersible pump 2 reaches a preset working time.

[0029] In this embodiment, the preset working time can be set to 40 minutes according to the test requirements. When the submersible pump 2 has been running for 40 minutes, the relay 3 disconnects the power supply to the submersible pump 2, and the rain test system does not need to be manually shut down.

[0030] Further, see Figure 1 As shown, in some embodiments, a spring clip 9 is fixedly installed inside the water tank 4, and the spring clip 9 is used to set the mounting position of the device under test.

[0031] In this embodiment, the device under test 8 can be configured as an RSU road test unit. The rain test system is used to test the sealing performance of the RSU road test unit. A bracket is provided in the water tank 4. The bracket fixes the rain nozzle 5 and the spring clip 9. The rain nozzle 5 is located above the spring clip 9. The spring clip 9 is used to hold the RSU road test unit. The spring clip 9 can extend and retract. During the process of the rain nozzle 5 spraying water, the RSU road test unit can be shaken by the spring clip 9 to simulate the effect of outdoor wind to perform performance testing on the RSU road test unit. The rain test system can be used in conjunction with other test systems without the need for additional development for different test schemes.

[0032] Further, see Figure 1 As shown, in some embodiments, the bottom of the water tank 4 is provided with a conduit 10, which connects the water tank 1 and the water tank 4.

[0033] In this embodiment, the conduit 10 extends into the water tank 1, and the opening of the conduit 10 faces the water tank 1. The conduit 10 connects the water tank 1 and the water trough 4, so that the water collected in the water trough 4 can flow into the water tank 1 through the conduit 10, thereby realizing the recycling of the water in the water tank 1 between the water tank 1 and the water trough 4. The length of the conduit 10 can be adjusted according to the actual situation.

[0034] Further, see Figure 1As shown, in some embodiments, the controller 7 is electrically connected to the relay 3 via a second network cable.

[0035] In this embodiment, the relay 3 has a USB interface, which is electrically connected to the controller 7 via the second network cable. This allows the controller 7 to send commands to the relay 3 via the second network cable and control the power supply to the submersible pump 2. The controller 7 can display the control program of the relay 3 and adjust the control program of the relay 3. In other embodiments, the relay 3 and the controller 7 can be connected by a signal connection.

[0036] Further, see Figure 1 As shown, in some embodiments, the capacity of the water tank 1 is set to 30-70L.

[0037] In this embodiment, the capacity of the water tank 1 can be set to 30-70L. Preferably, the capacity of the water tank 1 is set to 50L, so that the water tank 1 has the smallest volume while meeting the water requirements of the rain test.

[0038] Further, see Figure 1 As shown, in some embodiments, the length of the water tank 4 is greater than the length of the water tank 1.

[0039] In this embodiment, the length of the water tank 4 can be set to be greater than the length of the water tank 1 to meet the water collection requirements of the rain nozzle 5 at different heights and under different water volume conditions, so as to simulate different outdoor rainy day conditions.

[0040] Further, see Figure 1 As shown, in some embodiments, the rain nozzle 5 includes a plurality of nozzles, which are spaced apart.

[0041] In this embodiment, the rain nozzle 5 includes multiple nozzles, which are spaced apart, so that the rain test system can spray water from different directions and more closely resemble the real situation when simulating outdoor rainy days.

[0042] Further, see Figure 1 As shown, in some embodiments, the diameter of each nozzle is set to 0.5 to 4.5 mm.

[0043] In this embodiment, the diameter of each nozzle can be set to 0.5 to 4.5 mm, preferably 2.5 mm, so that the water sprayed by the nozzle is ejected at a suitable range, making the rain test system more realistic when simulating outdoor rainy days.

[0044] Before using the rain test system, the RSU road test unit is mounted on the spring clip 9, and then water is added to the water tank 4 until the water level in the water tank 1 meets the test requirements. Then, the preset working time of the submersible pump 2 is set on the relay 3. The rain test system is then turned on to start testing the sealing performance of the RSU road test unit. When the PC detects an abnormality in the RSU road test unit, the PC sends a command to the relay 3 and controls the relay 3 to disconnect the power supply to the submersible pump 2, so that the rain test system stops in time to avoid damage to the components of the RSU road test unit due to continuous rain. When the RSU road test unit has no abnormalities after the preset working time, the submersible pump 2 will automatically cut off the power after the preset working time is reached.
