Description

Technical Field

[0001] The present invention relates to the technical field of sign management in hydropower plants, and more particularly to an intelligent sign management system and its usage method. Background Art

[0002] Hydropower generation, as an important part of China's energy system, also plays an important role in China's energy distribution structure. Hydropower plants are distributed throughout the country. Most hydropower plants are built in areas with rich water resources, mostly located in deep mountains and lakes. At the same time, a hydropower plant covers a large area, and related equipment is distributed in different regions and at a relatively long distance. The equipment in hydropower plants undertakes the important task of hydropower generation. Ensuring the normal and stable operation of hydropower station equipment is the core of all work. Therefore, it is necessary to ensure the smooth progress of the equipment maintenance work in hydropower stations.

[0003] Currently, when performing maintenance or repair work on related equipment in a hydropower plant, corresponding signboards need to be hung, which is convenient for the operating personnel passing by to clarify the status of the equipment and avoid unnecessary safety accidents caused by ignorance.

[0004] However, when daily staff execute operation tickets and work ticket information as required, during the placement of signboards, there are often situations where multiple working surfaces of a single piece of equipment require the hanging of safety signboards. In this case, the safety measures for the working surfaces of the equipment overlap, resulting in a large number of hanging safety signboards and causing confusion. Different operating personnel need to re-check in the system and then retrieve the corresponding signboards after the operation is completed, which greatly increases the workload of the staff and reduces work efficiency.

[0005] At the work site, there is usually a situation where the person permitting the work ticket is not the same as the person retrieving the signboard at the end. Due to the asymmetry of information, it is not possible to clearly know the specific location of the signboard when retrieving it. Or when the equipment to be repaired and maintained is large equipment, the signboard is hung in a certain place, and it takes a long time to retrieve the signboard, which greatly reduces work efficiency.

[0006] Based on the above problems, hydropower plants lack an intelligent closed-loop management tool for the entire life cycle of safety signboards. Summary of the Invention

[0067] Embodiment 1

[0068] The intelligent sign management system includes a handheld terminal 1 and a background management system 2. The handheld terminal 1 includes a housing 11, a touch screen 12, a data storage interface 13, a main control chip 14, a camera module 15, a voice recognition module 16, a spatial positioning module 17, a power supply module 18, and a communication module 19. The touch screen 12 is installed on the housing 11. The data storage interface 13, the main control chip 14, the camera module 15, the voice recognition module 16, the spatial positioning module 17, the power supply module 18, and the communication module 19 are all integrated inside the housing 11. The data storage interface 13 and the power supply interface 181 of the power supply module 18 are located on the side of the housing 11. The cameras 151 of the camera module 15 are located in front of and behind the housing 11.

[0069] In this embodiment, as Figure 1 shown, the intelligent sign management system includes a handheld terminal 1 and a background management system 2. Through the data communication between the handheld terminal 1 and the background management system 2, the intelligent closed-loop management of on-site signs in a hydropower plant is realized, the standardization of sign use is enhanced, and the safety risk is reduced. The handheld terminal 1 is used for the identification of on-site staff permissions and the acquisition of sign-related information. At the same time, a space positioning module 17 is built into the handheld terminal 1, which can obtain its position information in a timely manner during the use stage of the sign, facilitating the timely recovery by the recycler and improving the recycling work efficiency of the sign. The background management system 2 is used to realize the intelligent management of signs, ensure a high circulation rate of signs on-site, and reduce production costs.

[0070] In this embodiment, as Figure 1 shown, the data transmission process between the handheld terminal 1 and the background management system 2 is that the handheld terminal 1 uploads the binding of the sign to the work order, and the background management system 2 issues an instruction to recycle the sign. The handheld terminal 1 of this intelligent sign management system is interconnected with the background management system to realize the intelligent management of the entire life cycle of the sign.

[0071] In this embodiment, as Figure 2 、 Figure 3 shown, the cameras 151 of the camera module 15 are located in front of and behind the housing 11. The camera 151 in front of the housing 11 is mainly used for face recognition of the user to ensure that the user's permissions are authorized in the system. The camera 151 behind the housing 11 is mainly used for information recognition of the sign. In this embodiment, there are two cameras 151 at the back. The setting of dual cameras facilitates improving the recognition efficiency of the sign.

[0072] In this embodiment, as Figure 2 shown, the data storage interface 13 and the power interface 181 of the power module 18 are located on the side of the housing 11. The data storage interface 13 is used for the transmission of data of the storage module, and the power interface 181 is used for charging the handheld terminal 1, thereby providing power for the handheld terminal 1.

[0073] The camera module 15 is used for the identification of sign information and the identification of operator information;

[0074] The voice recognition module 16 is used to receive the voice information of the operator and convert it;

[0075] The space positioning module 17 is used for obtaining the position of the sign;

[0076] The power module 18 provides electrical energy for the operation of the handheld terminal;

[0077] The data storage interface 13 is used for the transmission of information within the handheld terminal;

[0078] The communication module 19 is used for data transmission between the handheld terminal 1 and the background management system 2;

[0079] The background management system 2 is used for binding work ticket information of the handheld terminal 1, monitoring the status and location of identification plates, and tracing identification plate data.

[0080] In this embodiment, the camera module 15 within the handheld terminal 1 is used for identifying identification plate information and operator information; the voice recognition module 16 is used for receiving the voice information of the operator and converting it; by establishing the connection between the identification plate and the work order number through the camera module 15 and the voice recognition module 16, the intelligent management of the identification plate is realized through the background management system 1, thereby improving the management efficiency and ensuring the work quality.

[0081] Specifically, the communication module 19 adopts WIFI or 4G or 5G.

[0082] In this embodiment, the communication methods of 4G or 5G are stable and reliable, ensuring the stable and effective operation of the intelligent identification plate management system. WIFI can also be used for communication, which has high security within the local area network. In actual use, it can be selected according to the actual network status of the hydropower plant to select a reliable communication method.

[0083] Specifically, the spatial positioning module 17 adopts a GPS / Beidou dual-mode positioning unit.

[0084] In this embodiment, the spatial positioning module 17 adopts a GPS / Beidou dual-mode positioning unit, which has the following advantages:

[0085] Global coverage and compatibility. Both the GPS and Beidou systems have the ability to cover the globe and can provide continuous and all-weather navigation and positioning services for users;

[0086] High-precision positioning. The GPS and Beidou systems each have their own advantages in positioning accuracy. The positioning accuracy of GPS is relatively high, and the positioning accuracy of the Beidou system can also reach within 1 meter, and even reach centimeter-level accuracy in some areas;

[0087] Anti-interference ability and signal stability. The Beidou system uses triple-frequency signals, which can better eliminate the influence of high-order ionospheric delay and improve the reliability and anti-interference ability of positioning. Although GPS mainly uses dual-frequency signals and performs well in anti-interference;

[0088] Based on the above advantages, the precise positioning of the corresponding identification plate can be realized through the design of the dual-mode positioning unit, thereby improving the efficiency during the operation stage or the identification plate recycling stage.

[0089] Specifically, the information of the identification signs recognized by the camera module 15 is obtained through image features, including the name and number of the identification signs.

[0090] In this embodiment, since the main differences between the identification signs actually used on-site lie in their shapes and the content on the signs, there are various types of safety identification signs. Among them, several typical identification signs include:

[0091] 25 cm * 25 cm, with content such as "Work Here", "Maintenance Area", "Please Register When Entering and Exiting", etc. marked on it;

[0092] 24 cm * 30 cm, with content such as "No Throwing", "Beware of Tripping", "No Crossing", "Unauthorized Entry Prohibited", etc. marked on it;

[0093] 6 cm * 8 cm, with content such as "Do Not Operate, Someone Is Working", "Do Not Close Switch, Someone Is Working", etc. marked on it.

[0094] In the actual management process, due to the variety of identification signs, the identification sign number and name can be designed at the lower right corner of the front of the identification sign during production. In this way, each identification sign has a unique distinguishing feature, and the camera module can identify its number and name through the captured identification sign image to ensure the effective operation of the identification sign intelligent management system.

[0095] Specifically, the main control chip 14 uses an ESP32 chip.

[0096] In this embodiment, the ESP32 chip can be selected. The ESP32 chip has the following advantages:

[0097] Low power consumption, supporting multiple power-saving modes, such as deep sleep mode, which can effectively reduce the power consumption of the system and extend the battery life;

[0098] High integration, ESP32 is a highly integrated Wi-Fi + Bluetooth solution. At the same time, the advanced self-calibration circuit realizes dynamic automatic adjustment, eliminates the defects of external circuits, and better adapts to the changes of the external environment;

[0099] Powerful processing ability, ESP32 is equipped with a dual-core 240 MHz processor and built-in WiFi and Bluetooth functions, with rich peripheral interfaces and powerful processing ability;

[0100] Based on the above advantages, this chip is selected as the main control chip of the intelligent identification sign management system.

[0101] Specifically, the binding of the work ticket information of the background management system 2 is specifically to associate the identification sign with the work ticket information.

[0102] The monitoring of the sign status and position displays the position of the sign in the working area on the map based on the position information obtained by the spatial positioning module 17.

[0103] The sign data traceability is to store operation logs and responsibility traceability data.

[0104] In this embodiment, the functions of the above three functions of the background management system 2 are to synchronize the on-site usage situation of the sign to the background, which is convenient for the staff to view the usage situation in a timely manner, so as to avoid the sign being missed by the recycler after equipment repair and maintenance, resulting in the equipment remaining in the repair and maintenance state continuously, indirectly causing economic losses, and ensuring work efficiency.

[0109] Arrangement S03: Work order number information acquisition. The work permit issuer inputs the work order number by voice, and the communication module 17 on the handheld terminal 1 transmits the work order number to the background management system 2. The background management system 2 binds the sign in Arrangement S02 with the work order number according to the received work order number.

[0110] Arrangement S04: Sign hanging positioning. The work permit issuer hangs the sign, and the handheld terminal 1 records the position coordinates and transmits the position coordinate information to the background management system 2.
