Description

Technical Field

[0001] The present invention belongs to the technical field of hydropower station system management, and particularly relates to a shared positioning method and system for hydropower stations. Background Art

[0002] As an important energy infrastructure, the safety management of hydropower stations has always been a core issue in operation. The traditional method for positioning personnel in hydropower stations mainly relies on embedding positioning devices in safety helmets and monitoring the positions of personnel through technologies such as GPS, Bluetooth, or radio frequency.

[0003] However, this positioning method has obvious limitations. First of all, both the safety helmet and the positioning device are consumables and are prone to failure of the positioning function due to daily use or accidental damage, requiring frequent replacement or repair, which increases the maintenance cost and management difficulty. Secondly, traditional positioning devices are usually bound to specific personnel. Once the device is damaged or lost, the positioning function cannot be restored in time, affecting the continuity and effectiveness of safety management. In addition, the deployment and maintenance costs of current conventional positioning systems are relatively high, especially in large-scale hydropower stations, where the number of devices is huge and the management complexity increases significantly.

[0004] As an improvement, in recent years, RFID (Radio Frequency Identification) technology has gradually been applied to the field of personnel positioning. RFID technology automatically identifies target objects through radio frequency signals and obtains relevant data, and has advantages such as non-contact, fast reading, and multi-target identification. Some hydropower stations have tried to use RFID tags for personnel management, but existing RFID positioning solutions still have some problems. For example, current RFID tags are mostly for single use or bound to specific personnel, and cannot achieve the sharing and reuse of tags, resulting in waste of tag resources and increased management costs. In addition, the information management mechanism of existing RFID systems is relatively simple, lacking dynamic monitoring and efficient management of tag status, and it is difficult to meet the complex safety management requirements of hydropower stations. Therefore, in summary, the current methods for positioning personnel in hydropower stations have relatively low resource utilization rates, the relevant devices are vulnerable, and the management is relatively complex.

[0010] Further, in S2, the RFID reader supports simultaneous reading of several shared RFID positioning tags.

[0011] In some embodiments, in S2, after canceling the information of the shared RFID positioning tag, update the status of the shared RFID positioning tag in the database system to a blank state, and upload the cancellation record to the database system.

[0012] In some embodiments, in S2, the database system can notify the staff in the dangerous area to evacuate through the positioning notification of the shared RFID positioning tag, and the database system can provide an evacuation route for the staff according to the preset emergency evacuation route and the real-time position of the shared RFID positioning tag.

[0013] In some embodiments, in S2, the database system has an encrypted communication protocol. The database system monitors the position of the shared RFID positioning tag in real time, and gives early warnings and records the behavior of unauthorized entry into the preset area according to the preset security area and permission settings.

[0014] In some embodiments, S3 is further included. The RFID reader-writer, the face recognition device and the database system are maintained and updated at preset time intervals, and preventive maintenance and fault troubleshooting are carried out according to the logs and fault records of the database system.

[0015] The present invention also provides a shared positioning system for a hydropower station. The system includes a data integration module, an inbound processing module and an outbound processing module; wherein: The data integration module is used to store personal information, the information status of the shared RFID positioning tag and other data through the database system; a face recognition device and an RFID reader-writer are respectively configured at the entrance and exit of the hydropower station; The inbound processing module is used to, in the case of a person to enter the station, place the shared RFID positioning tag on the RFID reader-writer, and the database system reads the information of the shared RFID positioning tag; if the information of the shared RFID positioning tag is in a blank state, the personal information of the person to enter the station is automatically matched through the face recognition device.
