[0002] In industries such as metallurgy and chemicals, equipment operation permissions are typically managed using physical control cards. Traditional control cards are card-style plastic or metal products that need to be hung on fixed signs. When control cards are moved, permissions must be manually verified, which presents the following problems:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; in the description of this utility model, "a plurality of" or "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] Please see Figures 1 to 6 As shown, this utility model is an operation sign device with status display, including an operation sign base plate 100, a photoelectric sensor 300, an indicator light 400, and a switching power supply 500. The photoelectric sensor 300 is installed at the center of the operation sign base plate 100, and the indicator light 400 is installed at the upper part of the operation sign base plate 100. The two are connected in series and powered by the switching power supply 500. When the operation sign 200 leaves the corresponding operation sign base plate 100, the signal of the photoelectric sensor 300 is interrupted, and the indicator light 400 lights up; when the operation sign 200 returns to its original position, the photoelectric sensor 300 is triggered, and the indicator light 400 turns off.

[0034] During use, the operation board 200 device of this application is powered by a photoelectric sensor 300 and an indicator light 400 installed on the operation board base plate 100, which are connected in series and powered by a switching power supply 500. Figure 4The electrical schematic diagram shows that when the control panel 200 is removed, the photoelectric sensor 300 stops sensing. Since there is no reflective surface in front of the sensor, the infrared light cannot be captured by the receiver, resulting in a "departure" status. A low-level signal is output, and the indicator light 400 illuminates red. Upon returning to its original position, the sensor resumes sensing. The infrared light emitted by the photoelectric sensor 300 is reflected by the control panel 200. The receiver receives the reflected signal, determines "present," outputs a high-level signal, and the indicator light 400 turns off. This application uses the linkage between the photoelectric sensor 300 and the indicator light 400 to provide real-time feedback on the status of the control panel 200, reducing manual verification steps, lowering the risk of misoperation, and thus improving safety management efficiency.

[0035] In the design of the operation sign 200 device of this application, the photoelectric sensor 300 is a diffuse reflection infrared sensor, the indicator light 400 is an LED red light, and the switching power supply 500 is installed on the bottom surface of the operation sign base plate 100 and is used to convert AC220V to 24V DC power. The operation sign base plate 100 is made of magnetic metal material, and a magnet is embedded on the back of the operation sign 200. The operation sign base plate 100 and the operation sign 200 are connected by magnetic attraction to facilitate the placement of the operation sign 200 on the operation sign base plate 100. The series circuit of the photoelectric sensor 300 and the indicator light 400 is wired in the hollow cavity inside the operation sign base plate 100 and connected to the switching power supply 500 for power supply, making operation convenient.

[0036] In this specific embodiment, the photoelectric sensor 300 and indicator light 400 signals are connected to the PLC control system. The PLC control system is connected to the host computer and displays the status of the operation sign 200 in real time. When the operation sign 200 leaves the signboard, the photoelectric sensor 300 interrupts its sensing and outputs a low-level signal. When the operation sign 200 returns to its original position, the sensor resumes sensing and outputs a high-level signal. The sensor signal is connected through the PLC's input module (DI module). The PLC scans the changes in the input port status in real time and binds the sensor input signal with the indicator light 400 output signal through the PLC control system. If the photoelectric sensor 300 signal is detected as "low level," corresponding to the operation sign 200 leaving its original position, the PLC controls the DO output module to send a power-on command to the corresponding indicator light 400, illuminating the red light. If the signal is detected as "high level," corresponding to the operation sign 200 returning to its original position, the PLC cuts off the power to the indicator light 400, and the red light goes out. When the PLC control system is connected to the host computer, the PLC connects to the host computer via industrial communication protocols (such as Modbus TCP, Profi bus, Ethernet / IP, etc.). The PLC packages the real-time status of each control panel 200 (such as "in place / out place") into data frames and uploads them to the host computer on a timed or event-triggered basis. This achieves the automated monitoring and remote management of the status of the control panels 200 through the PLC's "input-processing-output-communication" closed-loop control, which is suitable for industrial scenarios with high safety requirements.

[0037] It is important to understand that the PLC control system supports parallel processing of multiple control panels 200, and each photoelectric sensor 300 and indicator light 400 is assigned an independent input / output address to achieve branch control.

[0038] In this specific embodiment, a plurality of viewing areas are provided on one side surface of the operation board base plate 100, each viewing area corresponding to an operation board 200. The border line of the viewing area is consistent with the outline of the operation board 200, so as to be applicable to operation boards 200 of different sizes. Multiple viewing areas can be arranged on the operation board base plate 100 at the same time, and each viewing area is equipped with its own photoelectric sensor 300 and indicator light 400. The photoelectric sensor 300 and indicator light 400 of each viewing area are connected in series and can be connected in parallel with the photoelectric sensor 300 and indicator light 400 of other viewing areas, and are powered by a switching power supply 500.

[0039] In this specific embodiment, an RFID chip is provided on the back surface of the operation panel. This chip works in conjunction with a reader in the viewing area to verify access. During access verification, a unique identifier (UID) and associated access information (such as the operable device number, user identity, and validity period) are written into the RFID chip of each operation panel 200. The data is protected by an encryption algorithm (such as AES-128). The reader continuously emits radio frequency signals (such as 13.56MHz high frequency or UHF band) to form a sensing area. When the operation panel 200 enters the sensing area (typically within 1m of the reader), the RFID chip... The antenna receives radio frequency energy to activate and returns the stored data to the reader. The reader then transmits the acquired UID and permission information to the host computer via a communication interface (such as RS-485 or Ethernet). The system retrieves the preset permission table in the database and compares the permissions of the operation tag 200 with the currently requested operation (e.g., whether the maintenance personnel have the permission to operate the target equipment). Warnings and reminders can be issued. This application uses RFID technology to achieve precise control of permissions, effectively solving the problem that traditional operation tags 200 are easily misused or mistakenly taken. It is suitable for industrial scenarios with high security requirements (such as power and chemical industries).

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
