[0033] The image acquisition module 30 is configured to acquire images of the maintenance equipment before, during and after the maintenance;

[0034] The image recognition module 50 is configured to perform consistency comparison on the equipment state of the maintenance position marked in the secondary safety measure ticket in the photos taken during and after the maintenance and the photos taken before the maintenance, respectively;

[0035] The alarm module 60 is connected with the image recognition module 50, and is configured to perform alarm prompt when the consistency comparison is unsuccessful.

[0036] In the embodiment, the safety measure ticket generation module 10 can quickly generate a secondary safety measure ticket, and the generation efficiency of the safety measure ticket can be further improved by the voice input mode, thereby improving the execution efficiency of the maintenance task. In addition, the image recognition module 50 can verify the operation during the maintenance to ensure the compliance of the operation, and avoid the problem of execution error during the equipment maintenance, thereby causing accidents such as misoperation and refusal of the relay protection equipment.

[0037] The database module 20 can store typical secondary safety measure tickets. For example, the secondary safety measure tickets of the specific embodiment are classified and indexed according to voltage levels, interval types, equipment types, etc., and the typical secondary safety measure tickets in the historical safety measure ticket data of each classification are saved to the database.

[0038] The database module 20 also stores template safety measure tickets. For example, an index directory is established according to plant and station types, voltage levels, wiring methods, object types, protection device types, and maintenance work types, and a template of a secondary safety measure ticket corresponding to each classification is defined and stored in the database as a template safety measure ticket. When constructing the safety measure ticket template, secondary safety measure related terms and standard processes covering the power maintenance profession can also be collected and sorted. These terms and processes should be able to cover the safety measure requirements of various equipment and systems, as well as common operation steps and safety regulations.

[0039] Of course, the database module 20 also supports adding, deleting and editing the stored content.

[0040] For the safety ticket generation module 10, it can find the typical secondary safety ticket for the current task from the database module 20 according to the maintenance task requirements, so as to generate the secondary safety measure ticket. Through the new task function, the corresponding template safety ticket can be matched from the database module 20 according to the maintenance object and the maintenance work type input by the maintenance personnel, and the secondary safety measure ticket can be further obtained by the maintenance personnel filling the template safety ticket.

[0043] For the image recognition module 50, it is used for consistency comparison of the equipment state of the maintenance position. For example, before the maintenance, the terminals to be removed in the safety task of the secondary safety measure ticket are photographed, and the terminals to be removed are marked in the pre-maintenance photo. After the terminals are removed during the maintenance, the terminal row is photographed again, and the photo is compared with the pre-maintenance photo. If all the marked terminals are removed, the safety task is completed, otherwise, the alarm module 60 is used for alarm to prompt the maintenance personnel to check whether the terminal removal is performed according to the content of the secondary safety measure ticket. After the completion of the safety task, the maintenance personnel restores the terminals, and the terminal row is photographed again at this time. The image recognition module 50 compares the photo at this time with the pre-maintenance photo to determine whether all the removed terminals are restored. If not, the alarm module 60 is used for alarm prompt. In this way, through the image recognition and alarm prompt, it is ensured that each step of the safety measure is executed correctly and in place.

[0044] For the alarm module 60, it can specifically include a buzzer 61 and an alarm indicator light 62; the buzzer 61 is used for sounding when the alarm prompt is performed; the alarm indicator light 62 is used for lighting when the alarm prompt is performed. That is, the buzzer 61 and the alarm indicator light 62 are used for alarm prompt to the maintenance personnel at the same time.

[0045] In an embodiment, the terminal device further comprises a display module 70, which can be an LED or LCD display screen, for displaying data, such as the content, project, function, etc. of the safety measure ticket. The stylus 80 is used for manual writing and modification of the content in the secondary safety measure ticket by maintenance personnel, so that in a noisy environment, when voice input is not sensitive enough, writing operation is performed through the stylus 80.

[0046] The operation memory of the substation secondary anti-misoperation terminal device provided by the utility model should be not less than 8GB, and the storage capacity should be not less than 512GB, so as to ensure sufficient operation speed and memory for performing safety measure tasks and storing data.

[0047] In addition, the terminal device should further comprise a data interface for connecting a computer or a printer, so as to transmit the secondary safety measure ticket to the computer or print the secondary safety measure ticket through the printer. Of course, the terminal device and the computer and the printer can also be connected in a wireless communication mode.

[0048] The wireless communication module of the terminal device should also support communication connection with the substation operation and maintenance system, so that the substation operation and maintenance system can monitor the operation and maintenance state in real time and update the state in time.

[0049] Of course, the terminal device provided by the present scheme further comprises a shell, and the above-mentioned modules are integrally arranged in the shell. The size of the entire terminal device satisfies: the size satisfies (height 7.87 inches, width 5.3 inches, thickness 0.28 inches, and screen size 8.3 inches).

[0050] When the maintenance personnel receives the maintenance task, the secondary safety measure ticket is generated by calling the typical secondary safety measure ticket or inputting the maintenance object and the maintenance work type to search the template safety measure ticket and filling the content in the template safety measure ticket by using the safety measure ticket generation module 10 in the substation secondary anti-misoperation terminal device provided by the scheme, and the secondary safety measure ticket is generated, and the voice input mode can be used in the input process. Then, the terminal of the equipment needing maintenance in the secondary safety measure ticket is photographed by calling the camera, the terminal needing to be released in the safety measure task is marked after the photographing, and then the maintenance personnel performs the maintenance operation. After the maintenance personnel completes the maintenance, the terminal row is photographed again, the photograph taken at this time is compared with the photograph taken before the maintenance by the image recognition module 50, whether the released terminal is the terminal marked before the maintenance is determined, if not, the alarm module 60 is used for alarm prompt, and the maintenance personnel checks. If yes, the safety measure task is completed, the released terminal is connected and restored, and the terminal row is photographed again by calling the camera, and the photograph at this time and the photograph before the maintenance are compared and recognized by the image recognition module 50, whether the marked terminal is restored is determined; if yes, the maintenance is completed, and the secondary safety measure ticket is stored in the historical ticket library; if not, the alarm module 60 is used for alarm prompt, and the maintenance personnel checks whether the terminal is omitted or the unmarked terminal is operated.
