DETAILED DESCRIPTION

[0033] 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.

[0034] It should be noted that the present invention is a control cabinet for driver testing equipment, which is used to control the operation of several testing equipment. Since the driver can only be controlled and operated by the main control box after receiving instructions from the remote control, how to batch control the remote control to issue instructions has become a technical difficulty.

[0035] The control module of the present invention is connected to each control part through an RS485 communication line. In order to facilitate centralized control, the controller and each test device are connected through a switch bus control. At this time, the touch screen can also choose to communicate with the controller through the switch.

[0036] like Figure 1 , Figure 2 The central control operation cabinet of the electric bed drive life test equipment shown includes: a cabinet body 1 and five three-dimensional modules 2, a touch screen 3 for setting control parameters and a control module.

[0037] Among them, the cabinet includes a cabinet body, a bracket 12 and a cabinet door 11. The cabinet door 11 is arranged on one side of the cabinet body. Several brackets 12 for fixing the three-dimensional module 2 are arranged in the cabinet body. One side of the cabinet body is connected to a touch screen 3, a function key area 5, a parameter input device 4, a display 7, an alarm 6 connected to the controller, and a roller 10.

[0038] Furthermore, the cabinet body is provided with ventilation holes 13 and equipment heat dissipation exhaust holes 80 . The ventilation holes 13 are mainly used to dissipate the heat generated by the three-dimensional module 2 , and the equipment heat dissipation exhaust holes 80 are mainly used to dissipate the heat generated by the controller 8 .

[0039] Furthermore, the control module includes a motion controller and a controller. The motion controller is used to control the movement of the three-dimensional module. The motion controller is connected to the servo motor driver through a communication line. The controller is used to collect voltage and current signals of the servo motor and the main control box in the three-dimensional module and to collect analog pressure signals of the driver motor. The controller is connected to an analog input and output module and a voltage and current acquisition module.

[0040] The controller is connected to the touch screen via a communication line, and the motion controller, controller, and three-dimensional module are arranged in a cabinet.

[0041] Optionally, the controller may be disposed outside the cabinet, and communication between the controller and the motion controller and the touch screen may be established via a communication line.

[0042] In order to ensure that the driver is subjected to constant pressure during the test, the controller collects the analog value of the cylinder pressure exerted on the pressure sensor in the test equipment through the analog input and output module, converts the pressure analog value into the actual pressure value and compares it with the preset pressure value. According to the difference between the actual pressure value and the preset pressure value, the size of the proportional valve is changed, and the adjusted analog value is output to the proportional valve of the test equipment through the analog input and output module. The proportional valve adjusts the cylinder pressure. The increase / decrease of the cylinder pressure is proportional to the pressure exerted on the motor, so that the driver motor is subjected to constant pressure, meeting the stability and accuracy requirements of the test process.

[0048] Among them, the driver motor and the cylinder are arranged on the test equipment, the input end of the driver motor is connected to the output end of the main control box, and the analog input and output module transmits the received pressure analog value to the controller. The controller compares the pressure analog value with the set pressure value and transmits the pressure analog value through the analog input and output module to the proportional valve controlling the cylinder, so that the cylinder outputs a constant pressure to the driver motor.

[0049] Optionally, the motion controller can be started manually or automatically under the control of the controller.

[0050] Furthermore, the touch screen is used to set control parameters and display the operating status of the three-dimensional modules in each zone, and is connected to the controller for communication.

The Y-axis motor 210, the screw rod 211, and the Y-axis slide rail 213 are fixed on the base 214, the fixed slider 212 is connected to the mounting frame 202 at both ends of the mounting plate 203, and the two fixed sliders 212 are slidably connected to the screw rod 211 and the Y-axis slide rail 213 respectively. The Y-axis motor 210 drives the screw rod 211 to rotate, so that the mounting plate 203 moves forward and backward along the Y-axis slide rail.

[0056] like Figure 7 As shown, the Z-axis assembly is used to control the Z-axis movement of the pressing head, which includes a Z-axis motor 220, a Z-axis slide rail 221, a Z-axis belt 223, a pulley 222, and a connecting plate.

A connecting plate is fixed on the Z-axis belt 223, and the connecting plate is also connected to the cross bar 270. The fixed sliders at both ends of the cross bar 270 are located on the Z-axis slide rail 221. The rotation of the Z-axis motor 220 drives the Z-axis belt 223 to rotate. The rotation of the Z-axis belt 223 drives the cross bar 270 connected to the connecting plate to slide along the Z-axis slide rail 221, so that the cross bar 270 moves up and down along the Z-axis direction.

[0057] like Figure 5 , Figure 6 As shown, a tank chain 200 is also provided on the mounting plate 203 and the base 214 to facilitate the routing of the mounting plate 203 and the Z-axis carrier 205 during movement.

[0058] like Figure 8As shown, the remote control placement area includes a base plate, a fixed end 2401, and a clamp 2402. The clamp 2402 is connected to the clamp 2402 by a screw 2403. There is a groove 2404 on the base plate to match the remote control. The remote control 26 is fixed between the clamps. By adjusting the screw 2403, it can adapt to different remote control sizes.

[0059] Furthermore, the touch screen is used to set the motion parameters of the three-dimensional module, record the corresponding three-dimensional coordinates of the remote control buttons by running points and save them using the parameter input device for subsequent batch setting and downloading.

The temperature meter is connected to the thermocouple and the heating module, and the heating module includes a three-phase heating unit and a heating resistor. The three-phase heating unit is connected to control the heating resistor, and the thermocouple feeds back the temperature in the cabinet to the temperature control meter in real time. If the temperature exceeds the preset value, the controller starts the exhaust fan. If the temperature is lower than the preset value, the controller issues a heating command to control the three-phase heating unit, controls the heating resistor to heat, and circulates air through the circulating fan.

[0062] The exhaust fan and the circulation fan are arranged on the bracket 12 of the cabinet 1, preferably on the top bracket, and the heating module and the temperature meter are arranged on one side of the cabinet.

[0066] The controller described in the present invention is an intelligent control module with a single chip microcomputer such as an industrial computer, PC, PLC, MCU, etc.

[0067] In order to quickly collect the information of the driver, the controller is also connected to a barcode scanner via a communication bus, and the driver code input is completed by directly scanning the code.

[0068] During application, after the driver is installed on the test equipment, set the parameters through the touch screen, such as pressure, formula, upper and lower limits of voltage and current, input scan code and other parameters. Set the formula and select the operating area for the motion controller. When starting, first turn on the test cabinet to let the controller PC enter the data collection state, and then turn on the motion controller. During operation, the motion controller sends a signal to the controller PC. The motion controller returns information such as the remote control model and which function button. After receiving the signal, the controller PC collects, judges and records the data.

[0069] The communication connection method between the motion controller, three-dimensional module and controller described in the present invention can have many variations, such as wireless method, switch topology method, integrated control method, etc. The ultimate goal is to control the three-dimensional module to press the remote control in batches to control the main control box to complete the driver test. As for the pressure exerted on the driver, using a constant force can improve the stability and accuracy of the test. The functions of the test equipment can be designed as needed and will not be described in this patent.
