[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, as the first embodiment of the present utility model, a test device for simulating user remote control power on and off includes a power input interface 1, a protection module arranged at the output end of the power input interface 1, and a control module, a power supply module, and a first power output interface arranged at the output end of the protection module. It also includes a switch module controlled by the control module, the power supply module supplies power to the first power output interface, the switch module is arranged on the power supply line between the switch module and the first power output interface, the first power output interface is used to be electrically connected to the remote control to provide working power for the remote control, the control module controls the on and off of the switch module on the power supply line, and then controls the switch of the remote control connected to the first power output interface, simulating the user's remote control power on and off of the product to be tested.

[0022] Preferably, this example further includes a second power output interface, which is provided at the output end of the protection module and is used to output AC power.

[0023] In this example, the power input interface 1 is a 220V power plug. The protection module is a fuse T101 connected in series to the live wire L. This protection module can also be equipped with an overvoltage and overcurrent protection module such as an electrostatic tube or a voltage regulator tube to ensure the stability of the power supply of the device. The second power output interface in this example is an AC socket CJ101, which is used to power the product under test.

[0024] This example also includes a remote control, which is provided with a power input interface connected to the first power output interface, for cooperating with the first power input interface to power the remote control. Preferably, in this example, the first power output interface is a 3.3V DC socket J101, and the power input interface is a 3.3V DC input plug J201 that plugs into the 3.3V DC socket.

[0025] In this example, a BNC interface 2 is provided at the power output end of the switch module in parallel with the 3.3V DC socket J101. The BNC interface 2 is the connector between the wire and the camera when the camera device outputs, and can be connected to an external camera. Therefore, during testing, there is no need for personnel to be present, and only remote monitoring of the test situation is required.

[0026] Preferably, a power switch K101 is provided between the power input interface and the protection module. When testing is not required, the entire electrical power supply can be cut off by turning off the power switch K101. Of course, the power switch K101 can also be omitted in this example, and the same effect can be achieved by directly unplugging the 220V power plug.

[0027] The power switch in this example is a double-pole switch control module, which includes a first terminal for disconnecting the input power and a second terminal for connecting the power input interface 1 with the fuse T101.

[0028] The switch module in this example is an AC contactor JD101, the two ends of the induction coil of the AC contactor JD101 are connected to the control module, the power input pin of the AC contactor JD101 is connected to the output end of the power supply module, and the power output pin of the AC contactor JD101 is connected to the first power output interface.

[0029] The control module in this example is a digital time relay DH101 with digital display, wherein pin 2 of the digital time relay DH101 is connected to the neutral wire of the output end of the protection module, and pins 7 and 8 are respectively connected to the live wire of the output end of the protection module. Pins 6 and 5 of the digital time relay DH101 are two wiring contacts, and pins 2 and 6 of the digital time relay DH101 are respectively connected to the two ends of the induction coil of the AC contactor JD101, and pin 3 is the reset pin.

[0030] The power supply module in this example uses a switching power supply P101 that converts AC voltage into DC voltage. Other AC-to-DC power supply modules or power adapters available on the market can also be used.

[0031] As can be seen from the above description, the present invention has a simple and reliable structure. The electrical components used are all commercially available and only require wiring as required. This makes implementation easy and requires minimal development effort, as ordinary electricians can perform the task. During operation, simply setting the digital on / off time allows for power on / off testing via electrical control, making operation simple and convenient, with a wide range of applications.

[0032] The working principle of this utility model is:

[0033] When 220VAC 50Hz power enters through the power input interface, is controlled by the double-pole switch K101, and enters the fuse T101, it is divided into the following three paths (named A, B, and C in this example):

[0034] A circuit: input to the switching power supply (adapter) P101, the switching power supply P101 outputs DC3.3V voltage to the Y1 and Z1 pins of the AC contactor;

[0035] B-way: input to the digital display time relay DH101. By setting the time of HD101, the pin 6 of the relay has an alternating control voltage output, which accurately controls the conduction of the AC contactor JD101 and outputs a DC3.3V DC voltage to power the remote control. The power supply time is determined by the set time of the digital display time relay DH101.

[0036] In this example, the standby button of the remote control is always on. When the remote control is supplied with a DC3.3V power supply, the remote control starts to work and sends the power on / off code through the infrared transmitter. After the tested product receives the power on / off command sent by the remote control, there are two situations:

[0037] The first case: If the product under test is in the off state, it will turn on and enter the working state after receiving the command;

[0038] The second case: If the product under test is in the power-on state, it will shut down and enter the standby state after receiving the command; the power-on and standby time of the product are both controlled by the time digital display time relay DH101.

[0039] C: Input the spare AC socket CJ101, used to power the product under test.

[0040] The usage of the digital display time relay DH101 in this example is:

[0041] First, set the T1 and T2 time periods, times, and working modes. After power is turned on, T1 begins to delay, and the digital time relay DH101 is in a non-acting state (released). When T1 arrives, it indicates that the digital time relay DH101 is energized, and the left display is blanked, and T delay begins. When T2 delay arrives, the digital time relay DH101 is released again, and the right display is blanked. The single execution working mode ends here. If it is a cyclic working mode, T1 continues to delay, and the above process continues to perform delay state conversion. If the power is cut off for more than 1 second or a reset signal is input at any time during operation, the time will return to T1 = 0 and start timing, and the relay will be in a released state and start working again.

[0042] The simulated user remote control power on / off test device in this example is purely hardware controlled and safe and reliable. The device in this example can also be provided with a fireproof and explosion-proof housing, with all interfaces and sockets set on the housing, while the switching power supply P101, switch K101, fuse T101, AC contactor JD101 and digital display time relay DH101 are set inside the housing, thereby improving the reliability and safety of the equipment. The product developed and designed by this utility model has stronger adaptability, reliability and stability, and can be tested more reliably. Through reliability testing, problems in raw materials, structure, process, environmental adaptability and other aspects of the product can be discovered and improved, thereby improving the quality and performance of the product, providing users with a better user experience and increasing user satisfaction and loyalty to the product.

[0043] The specific implementation methods described above are preferred implementation methods of the present invention, and are not intended to limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to the specific implementation methods. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
