Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0023] Figure 1 It is a flow chart of the method for managing electric power warning signs based on high frequency communication provided in this embodiment.

[0024] like Figure 1 As shown, an electric power warning sign management method based on high frequency communication provided by an embodiment of the present invention, the electric power warning sign has a built-in UHF RFID communication module, the tool cabinet storing the electric power warning sign is provided with an UHF electronic channel device, and the UHF handheld terminal communicates with the electric power warning sign through the UHF communication module and the UHF electronic channel device. The method mainly includes the following steps: 101. When the power warning sign is taken out from the tool cabinet, the status uploaded through the ultra-high frequency electronic channel device is activated and available.

[0025] In a specific implementation process, before the intelligent management of power warning signs, the power warning signs and tool cabinets are first improved, and handheld terminals are equipped for the on-duty personnel. An ultra-high frequency RFID communication module is set inside the power warning sign, and the tool cabinet that stores the power warning sign uses an ultra-high frequency electronic channel device to ensure that the handheld terminal can establish a communication connection with the power warning sign and the tool cabinet, and can transmit information between them.

[0026] Therefore, when the power warning sign is taken out from the tool cabinet, the information of the power warning sign will be uploaded to the database through the electronic channel device. At this time, the database will mark its status as activated and available, indicating that the power knowledge sign taken out at this time is in a ready-to-use state.

[0027] 102. Receive the power outage equipment information issued by the work ticket system through the handheld terminal, and bind the power warning sign, power outage equipment and work ticket information.

[0028] When the power warning work sign is activated, the work ticket system will send the power outage equipment information to the handheld terminal, and the ultimate goal is to hang the power warning sign on the power outage equipment. At the same time, in order to prevent problems such as repeated hanging, the power warning sign, power outage equipment and work ticket information are bound, so that the power outage equipment, work ticket and power warning sign are in corresponding states. After binding, it cannot be bound to other power outage equipment before unbinding, ensuring the safety of personnel during maintenance.

[0029] Before binding, it is necessary to verify the consistency, accuracy and current status of the power warning sign module, power outage equipment and work ticket information; when the consistency and accuracy are correct and the current status is a bindable state, bind the power warning sign, power outage equipment and work ticket information to avoid incorrect binding and the occurrence of safety hazards.

[0030] When binding, the different identification codes of the power warning sign, power outage equipment and work ticket information are determined respectively; based on the different identification codes, a one-to-one mapping relationship between the power warning sign, power outage equipment and work ticket information is established to complete the binding. The actual binding is to establish a one-to-one correspondence between the data. Therefore, by identifying the identification code, the relationship between the three is established to ensure that the three appear as a whole after the binding is completed until the maintenance is completed and the binding is untied.

[0031] Similarly, before management, the first step is to traverse the identification data of all power equipment and power warning signs; based on the identification data, establish a power equipment database and a power warning sign database respectively; the identification data includes the code, specification, production date and failure rate. Ensure that the identification codes of power warning signs and power equipment are unique, ensure the accuracy of binding work, and improve the safety of maintenance work.

[0032] 103. Receive the task list for hanging power warning signs through the handheld terminal.

[0033] After the database receives the bound task, it will send the task list to the handheld terminal. The duty officer can clearly understand the power outage equipment number and power warning sign number in the current task list through the handheld terminal.

[0034] 104. Determine the equipment that needs to be shut down through a power outage through a handheld terminal, and hang corresponding power warning signs on the equipment that needs to be shut down based on the bound information.

[0035] After the number of the power outage equipment is determined, the specific location of the power outage equipment to be listed needs to be determined through the handheld terminal, and then the corresponding bound power warning sign is hung. After the hanging is completed, the status indicator light of the power outage equipment to be listed can be turned from on to off.

[0036] Check whether the task list of the work ticket is cleared. If it is cleared, receive other work ticket task lists. If it is not cleared, continue to hang the power warning signs, repeat the above steps until all the power warning signs in the work task list are hung, and end the current task list.

[0037] 105. When the work ticket is terminated, the power warning sign, power outage equipment and work ticket information are untied, and the hanging power warning sign is located through the handheld terminal to complete the recovery of the power warning sign, and the status of the power warning sign is changed to an inactivated state.

[0038] After the work ticket is terminated, the handheld terminal receives the unbinding command and completes the unbinding of the power warning sign, power outage equipment and work ticket information. Through the positioning of the finger terminal, the corresponding power warning sign is found to complete the recycling of all power warning signs. When the power warning sign is recycled to the tool cabinet, the electronic channel device will upload the information and modify the status of the corresponding power warning sign to an inactive state, thus completing the entire closed-loop management. The closed-loop monitoring of the entire process of power warning signs from taking to recycling is realized.

[0039] After completing the current work ticket task, process other work tickets. The work ticket processing system sends the power outage equipment information to the handheld terminal. The handheld terminal reads the available sign information. The database software repeatedly binds the equipment and power warning signs. The software system sends the task list for hanging power warning signs to the handheld terminal, and repeatedly hangs the signs on the equipment. Then the work ticket is pushed back. The work ticket processing system sends the work ticket push back task list to the handheld terminal. The power warning signs are scanned, located, and retrieved through the handheld terminal. At this time, they are not untied. When a single work ticket ends, the work ticket processing system sends a single work ticket termination task to the handheld terminal. The handheld terminal scans, locates, and retrieves the signs. At this time, the equipment, signs, and work tickets are untied.

[0040] Through intelligent monitoring of the entire process, the entire process of power warning signs can be traced, the equipment maintenance site is beautiful, and the labor intensity of hanging and retrieving signs is greatly reduced, ensuring that no accidental power supply accidents occur and ensuring the safety of maintenance equipment and personnel.

[0041] Furthermore, on the basis of the above-mentioned embodiment, after receiving the power outage equipment information issued by the work ticket system through the handheld terminal, this embodiment also includes: determining the number, type, applicable scenario, warning content and installation location of the power warning sign; determining whether the number, type, applicable scenario, warning content and installation location match the power outage equipment information; if they match, binding the power warning sign, the power outage equipment and the work ticket information; if they do not match, searching for a matching target power warning sign based on the power outage equipment information, and displaying the number of the target power warning sign, so as to use the target power warning sign to bind with the power outage equipment and the work ticket information. Specifically, matching the most reasonable power warning sign for different power outage equipment can ensure the efficient use of the power warning sign.

[0042] Furthermore, the present embodiment also includes: regularly maintaining and updating the data of the power warning sign; recording the time, personnel and content of each maintenance data update. When updating the data of the power warning sign, it includes: determining the identity information of the updater, and determining the operation authority based on the identity information; when the content of the data update meets the operation authority, the data update takes effect, otherwise the data update is not performed and a prompt message is issued.

[0043] Specifically, the information on the power warning sign is modified according to different permissions to avoid safety problems caused by information modification errors. At the same time, regular data updates can also enable timely replacement of the power warning sign when a failure occurs, ensuring management efficiency.

[0044] Furthermore, in this embodiment, the recycling of the power warning sign is completed, including: obtaining the ID information of the power warning sign to be recycled based on high-frequency communication; identifying the ID information based on high-frequency communication, obtaining the recycling position of the power warning sign to be recycled, and displaying the number of the recycling position to realize the recycling of the power warning sign to be recycled at the corresponding recycling position.

[0045] Specifically, by displaying the labels of the recycling locations, the neatness of all the electric warning signs can be better ensured, and the convenience of taking them can be ensured.

[0046] By adopting the management method of the electric power warning signs of the present invention, the maintenance equipment only needs to hang a single sign, and the equipment can be repeatedly hung by binding and unbinding within the software, which solves the problem that the maintenance equipment is disorganized and does not meet the management requirements after hanging multiple signs. In the workflow of repeated hanging and multiple collection of signs, the corresponding sign can be identified, located, and found through a handheld terminal, which reduces the workload of the attendant and reduces the tediousness. The sign can be accurately positioned from taking out the tool cabinet to hanging on site, collecting the sign, and returning it to the tool cabinet, solving the problem of lost and messy signs. The work of hanging signs on equipment is simplified to prevent accidents of mis-power supply and ensure the safety of equipment and personnel.
