Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0070] like Figures 1-8 As shown, the present invention proposes a management system for a sign hanging device 4, specifically including:

[0071] 1. An offline APP1 based on the Android system is installed on the inspection mobile phone 5 of the operation personnel for use during on-site inspections.

[0072] 2. Backend Server 2: Backend Server 2 manages user accounts, processes and stores data, and provides basic interactive functions.

[0073] 3. Data collector 3 is used to collect usage data of the sign hanging device 4 and send the collected data to the backend server 2.

[0074] When operators use sign 401, they first hang it on the corresponding sign hanging device 4. The auxiliary positioning device 402 fixed on the sign hanging device 4 and the identification module 404 attached to the side of the auxiliary positioning device 402, together with the data acquisition device 3, collect relevant information on the retrieval and return of sign 401. The data is processed and analyzed by the background server 2 and sent to the inspection mobile phone 5. The offline APP 1 installed on the inspection mobile phone 5 sends a signal to trigger the alarm of the auxiliary positioning device 402 on the sign hanging device 4. At the same time, the number of signs 401 is displayed on the inspection mobile phone 5. The alarm sound of the auxiliary positioning device 402 is used to locate the sign 401, helping the staff to determine the position of the sign 401.

[0075] The offline APP1 includes a signal transceiver module 101 and a detection module 102.

[0076] The signal transceiver module 101 is used to transmit the positioning signal of the sign 401 and receive the feedback signal from the auxiliary positioning device 402. After receiving the positioning signal, the auxiliary positioning device 402 performs corresponding actions and sends a feedback signal which is received by the signal transceiver module 101. Together with the detection module 102 of the offline APP1, the positioning of the sign 401 is completed.

[0077] The detection module 102 is used to display the number of signs 401 in the vicinity. When operators are patrolling the plant, they can detect the signs 401 through the signal transceiver module 101 of the inspection mobile phone 5. The detection module 102 then quickly generates a visual quantity display chart, showing the number of nearby sign hanging devices 4 in real time. This allows operators to quickly determine the number of signs 401 in the plant area through the inspection mobile phone 5 during their patrol. The auxiliary positioning device 402 of the sign hanging device 4 then sounds an alarm to determine the specific location of the sign 401. This effectively reduces the time cost for operators to find the signs 401 and enables them to complete inspection tasks such as information collection and status checks more efficiently.

[0078] The backend server 2 includes a login module 201, a data receiving module 202, a data analysis module 203, a data query module 204, a time management module 205, a storage module 206, and a communication module 207. The login module 201 ensures access security to the management system. The data receiving, analysis, and storage modules enable full-process processing of data generated during the use of the signboard 401. Simultaneously, the communication module 207 establishes a remote connection with the inspection mobile phone 5, allowing operators to conveniently query the status and time information of the signboard 401 fixed on the signboard hanging device 4, providing comprehensive and efficient support for the signboard management system.

[0079] The login module 201 is responsible for creating, storing and verifying operator accounts. It stores basic information of operators, including account and password, and is responsible for verification and basic connection when users log in, confirming the identity of operators through a dual verification mechanism.

[0080] Preferably, when storing account passwords, the login module 201 can use encryption technologies such as MD5 or SHA-256 to store account passwords, ensuring the security of sensitive information.

[0081] The data receiving module 202 is used to receive data sent by the acquisition unit 3. The acquisition unit 3 and the data receiving module 202 are connected through corresponding interfaces. After the data is acquired, it is transmitted to the data receiving module 202. The data receiving module 202 performs preliminary processing on the acquired data, and then transmits it when it is processed into data that can be received by the data analysis module 203.

[0082] The data analysis module 203 is used to analyze the data received by the data receiving module 202, calculate the usage time of the sign hanging device 4, and send the analyzed data to the data query and time management module 205 and the storage module 206.

[0083] The data query module 204 is used to query the usage status of the sign hanging device 4, including whether it is in use or has been put back.

[0084] The time management module 205 is used to query the time when the sign hanging device 4 is taken out and returned. Operators can quickly and accurately obtain relevant time information through this module.

[0085] The storage module 206 is used to store the usage information of the sign hanging device 4, including all information generated during the process of taking the sign hanging device 4 out and putting it back, including when it was taken out, when it was returned, the duration of use, and the usage status.

[0086] The communication module 207 is used to connect with the inspection mobile phone 5 with the offline APP 1 installed, and supports data interaction of the APP in offline mode.

[0087] The sign hanging device 4 is equipped with a sign 401 and an auxiliary positioning device 402. The auxiliary positioning device includes a smart item-finding tag 403, which integrates an identification module 404. The auxiliary positioning device 402 assists the offline APP 1 in locating the sign 401, and the identification module 404 and the data acquisition device 3 collect usage information of the sign 401. The backend server 2 assists in recording the usage of the sign 401, providing a more scientific and safer guarantee for the hanging and management of the sign 401 during maintenance.

[0088] Simultaneously, the identification module 404 and the smart item-finding tag 403 are installed on the sign hanging device 4. The number of sign hanging devices 4 is matched to the number of signs 401 used. Through the identification module 404, information regarding the retrieval and return of signs 401 is quickly recorded. Finally, data exchange is achieved between the backend server 2 and the inspection mobile phone 5, linking the auxiliary positioning device 402 with the inspection mobile phone 5. The number of signs 401 around the operator is displayed through signal interaction between the auxiliary positioning device 402 and the inspection mobile phone 5.

[0089] The sign hanging device 4 can be any commercially available device. It is only necessary to ensure that it can fix the sign 401 and the auxiliary positioning device 402 to the device in the factory area at the same time. For example, the following are some common types of sign hanging devices 4.

[0090] 1. Magnetic suspension clip: It uses strong magnetic stickers to adhere to the surface of metal equipment and fixes the sign and auxiliary positioning device through a buckle structure.

[0091] 2. Clamp-type fixing bracket: Made of elastic metal or high-strength plastic clamps, the tightness can be adjusted by rotating the nut, and it can be used to fix pipes, columnar equipment, etc.

[0092] 3. Clip-on suspension seat: It is equipped with a groove and a spring clip. After the sign and auxiliary positioning device are inserted into the groove, the clip will automatically lock.

[0093] 4. Hook-type rack: It has an adjustable hook and can be hung on the edge of the equipment, railings, etc. The bottom is designed with a platform for fixing signs and auxiliary positioning devices 402.

[0094] 5. Spring-clamped suspension clamp: The spring force is used to move the block within the outer shell of the device, so that the clamping structure can clamp and fix it.

[0095] The present invention discloses a management process for a management system of a sign hanging device 4:

[0096] 1. Take the fixed auxiliary positioning device 402 out of the safety tool cabinet and scan the acquisition piece 3 with the identification module 404;

[0097] 2. The management system's backend server 2 records the retrieval and return records of sign 401 and the hanging time period. The retrieval time is recorded for calculation when the usage time of sign 401 exceeds the limit. At the same time, the return time is recorded to avoid forgetting to retrieve sign 401 during maintenance work.

[0098] 3. The management system’s backend server 2 communicates with the inspection mobile phone 5 through the communication module 207 to record the usage information of the sign 401.

[0099] In another embodiment, the time management module 205 is also provided with an alert unit 209, which is set with a maximum hanging period for the sign 401. When the hanging time of the sign 401 exceeds the maximum hanging period, the operator is reminded that there is an uncollected sign 401 inside the factory area.

[0100] In another embodiment, the offline APP1 also includes an alarm module 103. The alarm module 103 receives data sent by the warning unit 209. When the operator carries the inspection mobile phone 5 with the offline APP1 installed on it to patrol the factory area, when the operator encounters a sign 401 that has been hung for a longer period than the maximum hanging period of the sign 401, the alarm module 103 of the inspection mobile phone 5 will issue a prompt sound effect and / or corresponding text to remind the operator that there is a sign 401 that has not been retrieved, so as to prevent the sign 401 from being forgotten to be retrieved.

[0101] Specifically, the inspection mobile phone 5 is set up with the page corresponding to the alarm module 103, which reminds the operation personnel through text on the screen and sound emitted by the mobile phone speaker.

[0102] Meanwhile, modules are set up on the backend server 2 and offline APP 1 to remind staff that the hanging time of sign 401 has exceeded the limit, providing double protection to ensure that sign 401 is retrieved in a timely manner.

[0103] In another embodiment, the smart item tag 403 integrates a Bluetooth module 405, and the Bluetooth module 405 in the auxiliary positioning device 402 is bound to the inspection mobile phone 5 with the offline APP 1 installed.

[0104] The auxiliary positioning device 402 connects to the inspection mobile phone 5 via Bluetooth. The mobile phone only displays the number of nearby sign hanging devices 4, not their locations. State Grid Corporation strictly prohibits external network devices within the factory premises; therefore, the auxiliary positioning device 402 and the inspection mobile phone 5 connect only via Bluetooth and do not connect to the external network, thus lacking positioning functionality. The inspection mobile phone 5, with the offline APP 1 installed, connects to the backend server 2 of the sign management system via its built-in communication module 207. During use, neither the inspection mobile phone 5 nor the auxiliary positioning device 402 needs to connect to the internet, ensuring network information security and preventing leaks.

[0105] In another embodiment, the smart object tracking tag 403 integrates a microcontroller 406 and a prompting module 407. The microcontroller 406 is used to analyze the signals received by the auxiliary positioning device 402 and control the prompting module 407 to operate. The prompting module 407 is used to emit a sound according to the instructions of the microcontroller 406.

[0106] The auxiliary positioning device 402 is connected to the inspection mobile phone 5 via Bluetooth. The mobile phone displays the number of signs 401 in the nearby area. The operator sends a positioning signal of the sign 401 through the inspection mobile phone 5. The auxiliary positioning device 402 on the sign hanging device 4 in the signal coverage area will make a sound to prompt the operator about the location of the sign 401, thereby determining the location of the sign 401.

[0107] In another embodiment, the identification module 404 uses a magnetic sticker to attach to the outside of the smart item tag 403.

[0108] In another embodiment, the data collection component uses a magnetic stripe card reader. The identification module 404 is placed on the magnetic stripe card reader to collect the usage information of the sign hanging device 4. The management system's sign 401 retrieval and return information recording functions both record information by swiping a magnetic card.

[0109] In another embodiment, the auxiliary positioning device 402 is powered by a button battery. Button batteries are non-disposable devices with low power consumption during use. Their effective connection distance with the inspection mobile phone 5 is within 10 meters, sufficient for operators to use for positioning during factory patrols. Furthermore, a single battery replacement allows for two years of use, increasing the durability and economy of the sign hanging device 4.

[0110] In another embodiment, the backend server 2 is also provided with a recording module 208, which is used to record the location of the sign 401, the operators using the sign 401 and their work groups.

[0111] Operators determine the position of sign 401 by using the sound signal emitted by the auxiliary positioning device 402, and then check whether sign 401 has been moved. The inspection process relies solely on the operator's observation, and the inspection results may contain errors. The background server 2 sets up the recording module 208 to record the position of sign 401 and sends the position data to the inspection mobile phone 5, so that operators can confirm whether sign 401 has been moved. If it is found that it has been moved, sign 401 can be quickly re-suspended.

[0112] In another embodiment, the sign hanging device 4 is provided with a lanyard hole, and the auxiliary positioning device 402 and the sign 401 are attached to the lanyard hole by a lanyard. Using the lanyard hole for fixing facilitates replacement. A station has nearly 1,000 signs 401 of various types. It would be too costly to set up a corresponding hanging device, auxiliary positioning device 402 and magnetic sticker for each sign 401. In addition, there would be no one to maintain it, so it cannot be used on a large scale. Placing the auxiliary positioning device 402 and magnetic sticker on the sign hanging device 4, about 50 of them are sufficient.

[0113] The present invention adds an auxiliary positioning device 402 to the sign hanging device 4, and sets an identification module 404 on the outside of the auxiliary positioning device 402. At the same time, a management system for use with the sign 401 is developed to realize the rapid entry of the storage and retrieval status of the sign 401 and the filling in of the hanging period of the sign 401, thereby standardizing the management of the sign 401 and avoiding the occurrence of the sign 401 being forgotten.

[0114] The backend server is equipped with an inspection mobile phone 5 that has the aforementioned offline APP1 installed. The inspection mobile phone 5 does not need to be connected to the external network, ensuring network security during use. It is only necessary to bind the auxiliary positioning device 402 to the inspection mobile phone 5 via Bluetooth, so that the operators can quickly determine the number of nearby signs 401 during the patrol. As needed, the auxiliary positioning device 402 on the sign hanging device 4 can emit a prompt sound to help the operators quickly locate the signs 401 and check whether the signs 401 are misplaced or missing, thus ensuring the safety of production work during maintenance.

[0115] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.

[0116] Many other changes and modifications can be made without departing from the concept and scope of this invention. It should be understood that this invention is not limited to the specific embodiments, and the scope of this invention is defined by the appended claims.
