TECHNICAL FIELD

[0001] The present application relates to the technical field of timing controller, and particularly relates to an intelligent timing controller. BACKGROUND

[0002] The timing controller is a device for controlling the operation of each component in the electronic system in a specific time sequence, and is widely used in the fields of automation, embedded system, display device, sensor, etc. The core function of the timing controller is to accurately control the timing of different signals to ensure that each component operates correctly at the right time.

[0003] With the continuous progress of electronic technology, 3D packaging and cloud collaboration have become important technical development directions in modern electronic systems. The introduction of these technologies has put forward new requirements and challenges for the design and application of timing controllers.

[0005] In the use process of the existing timing controller, the touch screen is used for control, but due to the influence of the use environment, such as the influence of humidity on the sensitivity of the touch screen, the change of the external environment will cause the touch screen to be not sensitive or misoperation, and the existing technology is not convenient for automatic periodic sensitivity detection of the touch screen.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

At the same time, it can drive the drive wheel to rotate, so that the moving frame moves automatically and adjusts the detection position.

[0019] 2. By setting up a cleaning sleeve, the cleaning sleeve can rotate while the transmission mechanism drives the stylus to perform detection. This allows the sponge ring on one side of the cleaning sleeve to clean the detection area of ​​the touch screen in advance. When performing sensitivity detection on the touch screen of the timing controller, the cleanliness of the touch screen surface is ensured, and surface contaminants will not cause the touch screen to be unresponsive or produce incorrect touch signals. This not only improves the accuracy and stability of the detection, but also enhances the efficiency and lifespan of the equipment.

[0020] 3. By installing a baffle on the moving base, the opening of the housing can be sealed when the moving base moves out to perform sensitivity testing on the touch screen, preventing dust or other debris from entering the housing. At the same time, when the adjustment bracket moves down to reset, it can drive the cleaning strip to move and handle the dust that falls on the moving base. When the moving base is retracted into the timing controller housing, it prevents dust from being brought into the equipment. This can effectively protect the electronic components inside the timing controller, reduce equipment failure or performance degradation caused by dust accumulation, and extend the service life of the equipment.

Detailed Implementation

[0031] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0032] like Figures 1-9 The intelligent timing controller shown includes a housing 1, a touch screen 2 fixedly mounted on the housing 1, a movable base 3 below the touch screen 2, a cleaning strip 4 slidably mounted on the movable base 3, an adjustment frame 5 above the cleaning strip 4, a movable frame 6 slidably mounted on the adjustment frame 5, a transmission mechanism 7 fixedly connected to the movable frame 6, a stylus 8 on one side of the transmission mechanism 7, and a cleaning sleeve 9 on the outside of the stylus 8.

[0033] The timing controller mainly consists of a sheet metal housing, a data acquisition board, a control board, and input / output boards. All components are domestically produced. The timing controller is 4U in size and can be installed in a standard network cabinet. It has 14 outputs, each with its own filter and current transformer, capable of acquiring voltage and current for each circuit. Twelve of these are programmable, time-division controlled outputs, while the remaining two are direct-through outputs to the cabinet controller. The maximum power per output is 2000W.

[0034] Touchscreen 2 has the following main functions:

[0035] Displays the total input and the voltage, current and power of each circuit;

[0036] Each circuit can be independently powered on and off;

[0037] It can perform one-button power-on / off function;

[0038] The menu settings can be accessed on the touchscreen 2, allowing users to edit circuit names and set time-sharing intervals (default time-sharing interval is 1 second).

[0039] The output loop of the timing controller is as follows:

[0040] Output circuit:

[0041] 2-channel PDU output, 220VAC 50Hz, 16A / channel;

[0042] 12-channel computer power output, 220VAC 50Hz, 10A / channel.

[0043] Communication loop: 1 UDP channel and 1 RS485 communication channel.

[0044] The power-on and power-off operating modes are local mode and remote mode.

[0045] The local mode mainly includes local manual power-on / off and one-button power-on / off. Manual power-on / off is achieved by manually clicking the buttons on each circuit of the touch screen 2 to realize the power-on / off function of each circuit. One-button power-on / off is achieved by clicking the one-button power-on / off button on the touch screen 2. The sequencer works according to the preset power-on / off logic and power-on / off interval time to realize the one-button power-on / off function.

[0046] In remote mode, automatic power-on can be achieved remotely. For example, when the timing controller is powered on and the instructor presses the one-button power-on button, the controller will automatically power on the devices (such as computers and switches) according to the preset settings.

[0047] When the timing controller is powered on, the power-on and power-off modes are divided into local mode and remote mode.

[0048] Local mode mainly includes local manual power on / off and one-button power on / off. Manual power on / off is achieved by manually clicking the buttons on each circuit on the touch screen 2 to realize the power on / off function of each circuit. One-button power on / off is achieved by clicking the one-button power on / off button on the touch screen 2. The sequencer works according to the preset power on / off logic and power on / off interval to realize the one-button power on / off function.

[0049] In remote mode, remote automatic power on / off can be achieved. For example, when the power input to the timing controller is turned on, and the instructor presses the one-button power on / off button, the controller will automatically turn on / off the devices (such as computers and switches) according to the preset settings.

[0050] like Figure 4 As shown, the movable base 3 is slidably fitted through the inner wall of the outer casing 1. A baffle 301 is fixedly connected to one side of the movable base 3, and an electric push rod A302 is fixedly connected to one side of the baffle 301. The other end of the electric push rod A302 is fixedly connected to the inner wall of the outer casing 1. A sliding groove 303 is provided on the other side of the movable base 3. The baffle 301 prevents dust from entering the outer casing 1 during testing.

[0051] like Figure 5 As shown, a slider 401 is fixedly connected to one end of the cleaning strip 4 near the slide groove 303. The slider 401 is slidably engaged with the inner wall of the slide groove 303. A spring 402 is fixedly connected to one end of the slider 401, and the other end of the spring 402 is fixedly connected to the inner wall of the slide groove 303. The top of the cleaning strip 4 is inclined. The spring 402 enables the cleaning strip 4 to automatically reset, and the inclined top of the cleaning strip 4 prevents dust from adhering to the top of the cleaning strip 4.

[0052] like Figure 6 As shown, a trapezoidal block 501 is fixedly connected to the bottom of the adjusting frame 5. The trapezoidal block 501 is in sliding contact with the outer wall of the cleaning strip 4. A limit groove 502 is formed on one side of the upper end of the adjusting frame 5. A fixed rack 503 is fixedly connected to the inner wall of the adjusting frame 5 below the limit groove 502. Two connecting rod groups 504 are symmetrically connected and rotatably connected on one side of the adjusting frame 5. The bottom end of the connecting rod group 504 is rotatably connected to the moving base 3. A motor A505 is fixedly connected to the bottom end of one of the connecting rod groups 504. The motor A505 is fixedly connected to the moving base 3. The trapezoidal block 501 drives the cleaning strip 4 to move. The motor A505 drives the connected connecting rod group 504 to rotate, so that the connecting rod group 504 can drive the adjusting frame 5 to move upward.

[0053] like Figure 7 As shown, a limiting block 601 is fixedly connected to one side of the movable frame 6, and the limiting block 601 is slidably engaged with the inner wall of the slide groove 303.

[0054] like Figure 7As shown, the transmission mechanism 7 includes a motor B701, which is fixedly connected to the movable frame 6. A worm gear 702 is fixedly connected to the output end of the motor B701. A worm wheel 703 is meshed and driven on one side of the worm gear 702. A rotating shaft 704 is fixedly connected to the worm wheel 703, and the rotating shaft 704 is rotatably connected to the movable frame 6. A drive wheel 705 is fixedly connected to the other end of the rotating shaft 704, and the drive wheel 705 meshes and drives a fixed rack 503. The worm gear 702 drives the rotating shaft 704 connected to the worm wheel 703 to rotate, which in turn drives the drive wheel 705 to rotate. Under the action of the drive wheel 705, the movable frame 6 moves.

[0055] A bent rod 706 is fixedly connected to the other end of the worm gear 702. A drive wheel 707 is fixedly connected to the top of the bent rod 706. A driven wheel 708 is meshed and driven on one side of the drive wheel 707. A drive shaft 709 is fixedly connected to the driven wheel 708. The other end of the drive shaft 709 is rotatably connected to the movable frame 6. A drive wheel A710 is fixedly connected to the end of the drive shaft 709 located inside the movable frame 6.

[0056] like Figure 8 As shown, the stylus 8 and the movable frame 6 are slidably connected. One end of the stylus 8 is in contact with the touchscreen 2, and the other end of the stylus 8 is fixedly connected to an electric actuator B801. The other end of the electric actuator B801 is fixedly connected to a movable rod 802, and the other end of the movable rod 802 is fixedly connected to a sliding frame 803. The inner wall of the sliding frame 803 is slidably connected to the outer wall of the middle part of the bent rod 706. The electric actuator B801 can adjust the pressing pressure of the stylus 8, improving the diversity of detection. The electric actuator B801 drives the stylus 8 to extend to a suitable length, and then the motor B701 drives the connected worm gear 702 to rotate, so that the worm gear 702 can drive the bent rod 706 to rotate, so that the bent rod 706 can drive the movable rod 802 connected to the sliding frame 803 to move back and forth, so that the movable rod 802 can drive the stylus 8 to move and touch the touchscreen 2.

[0057] By setting up a stylus 8, the transmission mechanism 7 drives the stylus 8 to move back and forth, replacing the finger touching the touch screen 2 to detect the sensitivity of the touch screen 2 of the timing controller. At the same time, it can drive the drive wheel 705 to rotate, so that the moving frame 6 moves automatically and adjusts the detection position. This reduces the uncertainty caused by manual intervention, improves the accuracy of sensitivity detection, avoids errors caused by inaccurate manual operation, and automatically performs sensitivity detection and calibration periodically, thereby reducing the performance degradation caused by environmental changes and ensuring that the touch screen 2 always maintains the best performance.

[0058] like Figure 9As shown, a sponge ring 901 is fixedly connected to one end of the cleaning sleeve 9, and the sponge ring 901 is in movable contact with the touch screen 2. A rotating sleeve 902 is fixedly connected to the other end of the cleaning sleeve 9, and the rotating sleeve 902 is rotatably connected to the inner wall of the movable frame 6. A transmission wheel B903 is fixedly connected to the end of the rotating sleeve 902 located on the inner wall of the movable frame 6, and the transmission wheel B903 is engaged with the transmission wheel A710 for transmission. When the movable frame 6 moves, the bending rod 706 drives the transmission shaft 709 connected to the driven wheel 708 to rotate through the connected driving wheel 707, so that the transmission shaft 709 can drive the connected transmission wheel A710 to rotate, so that the transmission wheel A710 can drive the rotating sleeve 902 connected to the transmission wheel B903 to rotate, so that the rotating sleeve 902 can drive the sponge ring 901 on the cleaning sleeve 9 to rotate.

[0059] Working principle: When it is necessary to test the sensitivity of the touch screen 2, the electric push rod A302 is used to drive the movable seat 3 connected to the baffle 301 to move out of the housing 1. Then, the motor A505 drives the connected linkage group 504 to rotate, so that the linkage group 504 can drive the adjustment frame 5 to move upward, so that the stylus 8 moves to one side of the touch screen 2 and the sponge ring 901 contacts the touch screen 2. When the adjustment frame 5 moves upward, the trapezoidal block 501 does not contact the cleaning strip 4. At this time, under the action of the spring 402, the cleaning strip 4 connected to the slider 401 will move to one side of the movable seat 3.

[0060] Then, the electric actuator B801 is used to drive the stylus 8 to extend to a suitable length. Then, the motor B701 drives the connected worm gear 702 to rotate, so that the worm gear 702 can drive the bending rod 706 to rotate, so that the bending rod 706 can drive the moving rod 802 connected to the sliding frame 803 to move back and forth, so that the moving rod 802 can drive the stylus 8 to move and touch the touch screen 2 to achieve sensitivity detection.

[0061] At the same time, the worm gear 702 will drive the rotating shaft 704 connected to the worm wheel 703 to rotate, so that the rotating shaft 704 can drive the connected drive wheel 705 to rotate. At this time, under the action of the drive wheel 705, the moving frame 6 will move, driving the stylus 8 to move laterally and adjust the detection position.

[0062] When the moving frame 6 moves, the bending rod 706 drives the drive shaft 709 connected to the driven wheel 708 to rotate through the connected drive wheel 707, so that the drive shaft 709 can drive the connected drive wheel A710 to rotate, so that the drive wheel A710 can drive the rotating sleeve 902 connected to the drive wheel B903 to rotate, so that the rotating sleeve 902 can drive the sponge ring 901 on the cleaning sleeve 9 to rotate, and perform cleaning pretreatment on the detection position of the touch screen 2. After the detection is completed, a report is automatically generated to help engineers analyze the performance problems of the touch screen 2 and adjust and maintain its sensitivity. When the adjustment frame 5 moves down to reset, it will contact and push the cleaning strip 4 through the adjustment frame 5 at the bottom, so that the cleaning strip 4 can handle the dust that falls on the surface of the moving seat 3.
