Due to safety control restrictions, this type of test environment is usually constructed in a confined space, and the equipment under test is placed in the confined space. During the test, the equipment under test needs to be repeatedly turned on and off, and parameters are set to check the performance status of the equipment under test. During this period, personnel need to enter or open the door to operate and collect data, which will inevitably cause changes in the test environment conditions in the confined space and affect the test results. At the same time, testers face personal safety risks due to improper protection.

[0033] The technical solution of the present invention is further clearly and completely described below in conjunction with the accompanying drawings and embodiments.

[0034] The present invention designs a "human-machine separation" safety control device to meet the testing requirements of rapid and repeated measurement of characteristic parameters, remote and stable control, and visualized data collection in extremely complex environments, thereby realizing personnel safety testing and data security collection.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] A low temperature test of a certain device is carried out in a high and low temperature and humidity test box to detect the operation of a certain device at -20℃. The tested device needs to be turned on and off regularly. If the box is opened for operation, the external environment will affect the test conditions in the box and the test results. The execution end of the present invention is placed in the test box, and the control box 7 is placed outside the test box 9. The control end 8 can be visually operated and collect data outside the test area (no less than 3 kilometers) through wires.

[0037] Figure 5 It is a schematic diagram of an embodiment of a remote automatic control device of the present invention.

[0038] The X-axis linear module 1, Y-axis linear module 2, electric claw 4, camera 5, and control terminal 8 in the figure can be purchased as shelf products and integrated, including processing and assembly of mounting plates, and software installation and debugging. The slide 3 and retractable support rod 6 are processed and assembled according to design requirements. The control box 7 is processed and assembled with circuit boards and shells according to actual task requirements.

[0039] Both the Y-axis linear module and the X-axis linear module are customized products of the MTH5 series of Chengdu Haike Industrial Control. The screw lead of the X-axis linear module 1 is 5mm, the effective stroke is 500mm, the load is 10kg, and the motor is a Delta servo motor with a power of 100W. The appearance dimensions of the X-axis linear module are 1800mmX175mmX130mm, and the appearance dimensions of the Y-axis linear module are 820mmX315mmX140mm. The mobile module is equipped with a zero point switch to ensure the consistency of its initial position.

[0040] like Figure 5 , adjust the retractable support rod 6 according to the internal size of the test box 9 so that it is pressed tightly against the wall of the test box 9 and is not easy to fall off; the X-axis linear module 1 is fixed on the retractable support rod 6; the slide table 3, the electric claw 4, and the camera 5 are installed and fixed on the Y-axis linear module 2; the Y-axis linear module 2 is installed and fixed on the X-axis linear module 1;

[0041] Adapter boxes are arranged on the X-axis linear module 1, the Y-axis linear module 2 and the slide 3, and the control box 7 is connected to the adapter boxes of the X-axis linear module 1, the Y-axis linear module 2 and the slide 3 through cables;

[0042] The main body of the adapter box is made of aluminum alloy to reduce weight, facilitate the connection and wiring of wires, and effectively protect the internal electrical connections.

[0043] The control terminal 8 and the control box 7 can be connected via wired / wireless connection and the network protocol is configured.

[0044] Furthermore, in order to ensure the safety of the linear module, when the moving parts of the linear module reach the set limit position, the module will be physically limited by the limit block to limit the maximum movement stroke and ensure the safety of the module operation.

[0045] At the same time, the soft limit can be completed through the PLC and encoder values, and the motion range limit of the linear module can be set in the control software. When the position feedback signal of the linear module shows that its moving parts are close to or reach the set soft limit position, the control system will issue instructions according to the preset program, gradually reduce the speed of the motor, and finally stop the operation of the motor, thereby limiting the range of motion of the module.

[0046] A testing method for a remote automatic control device specifically comprises the following steps:

[0047] Step 1: configure the network protocol between the control terminal 8 and the control box 7 so that the device meets the test state;

[0048] Step 2: Place the device under test 10 at one end of the test box 9 close to the electric claw 4, and adjust the electric claw 4 at the execution end so that the position of the electric claw 4 and the button of the device under test 10 are consistent;

[0049] Step 3: According to the actual task requirements, the control terminal 8 designs the control program, including the key strength, position coordinates, key sequence, and time interval;

[0050] Step 4: After confirming that the program settings are correct, close the door of the test box 9 and start the test. According to the control program settings, the execution end clicks the buttons of the device under test 10 with the help of the electric claw 4. During the operation, the control end 8 is used to watch the implementation effect in real time, and the display information of the device under test is collected in real time;

[0051] Step 5: After the test, remove the device.

[0052] The effect achieved by the embodiment: the device can be quickly installed and withdrawn, and the buttons of the device under test in the test box can be accurately controlled from outside the test box; during the implementation, the present invention does not interfere with the normal operation of the device under test and the test conditions in the box, and during the test, personnel maintain a safe distance from the tested sample, and the tested state can be adjusted midway without opening the test box, which ensures the test effect and the personal safety of the test personnel.

[0053] The above contents are further detailed descriptions of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
