Description

Technical Field

[0001] This invention relates to the field of intelligent access control technology, specifically to an intelligent access control system. Background Technology

[0002] Electrical misoperation accidents are the most common type of safety accident during power plant operation. Once an accident occurs due to electrical misoperation, it can lead to equipment damage and unplanned unit shutdown, or even personal injury and death, resulting in huge economic losses. In most cases, it is caused by human factors. Although electrical equipment has five-proof interlocking functions, it can only reduce the error rate during routine operation and cannot eliminate accidents caused by personnel going to the wrong position. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing an intelligent access control system that combines technical and human security measures to fill gaps in current prevention and control measures. This system can reduce the error rate during routine operations and effectively prevent accidents caused by people going to the wrong location.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An intelligent access control system includes a main control system, a user information reading system, a door lock control system, and a periodic review system. The user information reading system, the door lock control system, and the periodic review system are all electrically connected to the main control system. The main control system is used for control and storage. The user information reading system is used to read the facial, fingerprint, RFID card, and corresponding password information of the staff. The door lock control system is used to control the opening and closing of the corresponding workshop door locks. The periodic review system is used to periodically review whether the operators of the equipment are compliant.

[0006] Furthermore, the main control system includes a data input module, a data storage module, a data processing module, a data verification module, a data review module, a control module, an authorization instruction module, an equipment anomaly alert module, and an automatic control and locking module. The data input module, data storage module, data processing module, data verification module, data review module, control module, authorization instruction module, equipment anomaly alert module, and automatic control and locking module are all electrically connected to the control module.

[0007] The data entry module is used to enter the worker's workshop, position, operating equipment, shift schedule, facial information, fingerprint information, RFID card, and corresponding password information.

[0008] The data storage module is used to store the worker's workshop, position, operating equipment, shift schedule, facial information, fingerprint information, RFID card, and corresponding password information.

[0009] The data processing module is used for maintenance and data recovery;

[0010] The data verification module is used to verify whether the information entered by the staff is the same as the content stored in the data storage module.

[0011] The data review module is used to verify whether the operators in the positions are compliant.

[0012] The control module is used to control the door lock control system, and the authorization instruction module is used to generate and send authorization instructions.

[0013] The device malfunction alert module is used to alert the administrator when the device malfunctions.

[0014] The automatic control and locking module is used to disable the operator's access rights when the equipment malfunctions, allowing the equipment to enter a short-term automatic operation state.

[0015] Furthermore, the authorization instruction module includes an authorization instruction generation module and an authorization instruction sending module. The authorization instruction generation module is used to generate an authorization instruction after verifying that the staff member's face, fingerprint, RFID card, and corresponding password information are correct. The authorization instruction sending module is used to send the generated authorization instruction to the door lock control system.

[0016] Furthermore, when the data verification module encounters an anomaly while accessing a data block, the data processing module acquires anomaly information, identifies the data block to be recovered based on the anomaly information, determines the data recovery type based on the storage location of the data block to be recovered, generates a data recovery request based on the data recovery type, establishes a global driver recovery list, adds the data block information to the list after generating the data recovery request to prevent duplicate generation of data recovery requests, adds the ID information of the data block to the driver recovery list after generating the data recovery request, and performs data recovery processing according to the corresponding data recovery type in the data recovery request.

[0017] A first priority queue and a second priority queue are preset, wherein the first priority queue has a higher priority than the second priority queue. Data recovery requests are submitted to the first priority queue, and the recovered data blocks automatically overwrite the abnormal data blocks.

[0018] Furthermore, the user information reading system is an access control host equipped with a camera, fingerprint reading function, RFID data collection function, and password input function.

[0019] The camera is used to collect facial information of staff.

[0020] The fingerprint reading function is a fingerprint reader used to acquire the fingerprint information of staff.

[0021] The RFID data acquisition function is a high-frequency RFID data acquisition terminal adapted to RFID cards.

[0022] The password input function is a password input device used to obtain passwords entered by staff.

[0023] Furthermore, the door lock control system includes access controllers for the boiler room, turbine room, deaerator room, coal bunker, coal conveying section, pulverizing workshop, high and low voltage power distribution room, water treatment workshop, air compressor station, flue gas purification section, wastewater treatment workshop, machine repair workshop, fuel transportation workshop, and thermal control workshop. These access controllers are respectively installed in the boiler room, turbine room, deaerator room, coal bunker, coal conveying section, pulverizing workshop, high and low voltage power distribution room, water treatment workshop, air compressor station, flue gas purification section, wastewater treatment workshop, machine repair workshop, fuel transportation workshop, and thermal control workshop.

[0024] Furthermore, the periodic review system includes monitoring instruments and alarms installed on boilers, turbines, generators, coal conveying systems, and other equipment in each workshop, as well as dynamic facial recognition devices installed on these same equipment. The monitoring instruments monitor the operational status of these equipment in each workshop to ensure they are functioning normally. The alarms are used to issue warnings and report any abnormalities to the main control system. The dynamic facial recognition devices identify the operator's facial information every half hour and send the results to the data review module. The data review module compares the operator's actual workshop, position, operating equipment, shift schedule, and facial information with the data in the data storage module. If any of these discrepancies is found, the automatic control and locking module disables the operator's access, putting the equipment into a short-term automatic operation state. Simultaneously, the alarms sound and report any abnormalities to the equipment anomaly alert module.

[0025] The beneficial effects of this invention are as follows: The main control system records each worker's workshop, position, operating equipment, shift schedule, facial information, fingerprint information, RFID card, and corresponding password information. The user information reading system identifies the worker's face, fingerprint, RFID card, and corresponding password information and sends this information to the main control system. When the worker's facial information, fingerprint information, RFID card, and corresponding password information all match, the main control system unlocks the corresponding workshop door, granting the worker entry permission. A periodic review system periodically checks whether the equipment operators are compliant. By ensuring that facial information, fingerprint information, RFID card, and corresponding password information all match, the combination of technical and human security measures prevents accidents caused by personnel going to the wrong location. This invention, by combining technical and human security measures, fills gaps in current prevention and control measures, reducing the error rate during routine operations and effectively preventing accidents caused by personnel going to the wrong location.
