Description
Technical Field
[0001] The present invention relates to the field of security, and in particular to a substation lock management system and method. Background Art
[0002] At present, the daily work of power plants involves a large number of non-five-protection key management, such as terminal boxes, mechanism boxes, control cabinets, ladders, high-voltage rooms, relay rooms, safety equipment rooms, and protection and measurement control cabinets, all of which have their own locks and keys. These huge numbers and various types of keys make key management and unlocking in substations a headache. It often takes a long time to find the corresponding key when unlocking, which not only brings troubles to the staff in finding keys, but also greatly reduces work efficiency, resulting in problems such as difficult key management and difficult record tracing, which makes safe operations risky and hidden dangers.
[0003] At present, for the safety management of production equipment and non-production equipment in the industrial field, various anti-error locks or auxiliary control locks are usually set on the equipment body or around the equipment to achieve anti-error locking and intelligent opening and closing lock management. This management method guarantees the safe operation of the equipment to a certain extent, but there are still technical defects and safety hazards. The existing mechanical keys have simple tooth shapes and are easy to be illegally copied. It is easy for external construction personnel to use copied mechanical keys to open unauthorized locks in all plants and stations, which poses a hidden danger to equipment operation and personnel safety. The existing anti-error keys and auxiliary control keys have different structures. The two keys cannot open each other. When unlocking, you need to carry both keys to the site, which is inconvenient to carry and use. Introducing an intelligent lock management system, so that one key can open the functions of all non-five-protection locks, simplifying key management, and can solve the above-mentioned problems. Summary of the invention
[0004] The purpose of the present invention is to provide a substation lock management system and method, which adopts a downward authorized operation ticket method, has the characteristics of disorderly and repeated unlocking, greatly reduces the workload of on-site key management, and significantly improves the work efficiency of on-site operators.
[0005] To achieve the above object, the present invention provides the following technical solutions: A substation lock management system, characterized in that it includes a single station mode and a centralized control mode; The single-station mode includes a workstation, which is an important part of the entire system. It undertakes the key tasks of storing relevant information and generating an unlocking sequence. The workstation is connected to a data transmission charging base, which uses short-range communication Bluetooth to transmit data. It is convenient, fast, stable and reliable, and can efficiently transmit data within a short distance. The workstation stores relevant information and can generate an unlocking sequence, which is sent to the computer key through the data transmission charging base. A code reading module is installed on the unlocking head of the computer key, which can be used to read the unique identification code of the auxiliary control lock. The identification code is like the identity card of the lock, ensuring that only authorized keys can open the corresponding lock.
[0006] Computer keys can open auxiliary control locks within the authorized range. Auxiliary control locks have built-in graded lock cores. Different lock cores are installed on equipment in different areas to achieve the locking function. The setting of graded lock cores can be customized for locking management according to the importance and security requirements of equipment in different areas.
[0007] The centralized control mode includes a centralized control center, which is equipped with servers and hosts. The centralized control center is the core management hub of the entire system. The servers and hosts work together to centrally manage the subordinate sub-control centers and sub-stations. The centralized control center is connected to several sub-control centers by optical fiber channels. Sub-control servers and sub-control hosts are configured in the sub-control centers. The sub-control hosts are connected to several sub-stations by optical fiber channels. The sub-control hosts all adopt the single-station mode; The centralized control center manages the auxiliary control locks of all substations under the system, the sub-control center can only manage the auxiliary control locks of the substations under its jurisdiction, and each substation can only manage the auxiliary control locks of its own station, adopting a top-down hierarchical centralized control management.
[0008] The auxiliary control lock can be transmitted through two modes: local workstation and remote transmission. The remote transmission mode is divided into two modes: network and SMS. In SMS mode, the operator can receive the unlocking sequence and send the operation information to the host through SMS on site without returning to the centralized control center. This method greatly improves work efficiency, especially in emergency situations, and can respond quickly.
[0009] The host records the unlocking person, unlocking time, and unlocking device information. The unlocking record data can be queried by unlocking person, time period, device name, etc. These detailed records provide a strong basis for subsequent query and management. The key also stores unlocking record recall data, which cannot be deleted by the user, ensuring the integrity and security of the record.
[0010] The relevant information of the devices in different areas is stored in the host, including the device name, lock code, geographic location, and associated device information, which is directly displayed on the software interface in a graphical form. The devices are classified according to geographic location, device voltage level, device type, and user usage habits. The classification method facilitates users to quickly find and manage devices.
[0011] The system reserves communication interfaces for the anti-mistake locking system and the substation auxiliary control system, and can be linked with the video surveillance system and the access control and anti-theft system in the later stage.
[0012] A substation lock management method, characterized in that it includes an authorized unlocking mode, a designated unlocking mode and a cross-application mode, and the authorized unlocking mode operator does not need to issue a corresponding authorized operation ticket, and specifically includes the following steps: S1: Identity verification. The operator logs in to the workstation and swipes the authorization card to verify the identity. After passing the identity verification, the operator enters the unlocked working mode. S2: Select the auxiliary control lock, select the auxiliary control lock to be unlocked in the unlocking mode. If the operator has the unlocking operation authority of the corresponding device, the unlocking sequence can be sent to the computer key through the data transmission charging dock; S3: On-site unlocking, the code reading module installed at the unlocking head of the computer key reads the unique identification code of the auxiliary control lock. When the identification codes match and the unlocking sequence is available, the unlocking function is realized; S4: Archive operation records, unlock and transmit operation records back to the workstation for query and statistics, including operation equipment auxiliary control lock information, authorization information, operation time, system operation and logout time, personnel login and logout time information; S5: Operation record upload: upload the operation record from the workstation to the server in the centralized control center through the optical fiber channel. The operation record stored in the server can be queried at any time in the centralized control center. In the designated unlocking mode, the operator does not need to choose to unlock the device. Once logged in, the operator can download the relevant unlocking authority to the computer key and unlock the device at any time. The specific steps include: S1: Role configuration. The roles of staff members include administrator, director, specialist, shift leader, shift attendant, and external personnel. The administrator is the highest level and can set and change the permissions of other personnel and authorize operation tickets downwards. S2: Identity verification. The operator logs in to the workstation and swipes the authorization card to authenticate the operator. After the authentication is passed, the operator enters the unlocked working mode. S3: Download the operation ticket. In the unlocking working mode, you can download the operation ticket authorized by the high-level role. The operation ticket is the unlocking sequence for a specific auxiliary control lock, which is divided into permanent authority work ticket and temporary authority work ticket; S4: On-site unlocking, the code reading module installed at the unlocking head of the computer key reads the unique identification code of the auxiliary control lock. When the identification codes match and the unlocking sequence is available, the unlocking function is realized; S5: Archive operation records, unlock and transmit operation records back to the workstation for query and statistics, including operation equipment auxiliary control lock information, authorization information, operation time, system operation and logout time, personnel login and logout time information; S6: Operation record upload: upload the operation record from the workstation to the server in the centralized control center through the optical fiber channel. The operation record stored in the server can be queried at any time in the centralized control center. The cross-application mode is an integration of the above two modes. The operator usually uses the authorized unlocking mode. When some devices are not within the operator's authorization range and the operator must temporarily unlock these devices, the designated unlocking mode can be used to temporarily authorize the operator to operate the device.
[0013] When the authority in the centralized control center, sub-control center or sub-station permits, an operation ticket can be sent out at the centralized control center, sub-control center or sub-station to authorize the operation ticket, so as to meet various on-site unlocking needs.
[0014] The host stores all auxiliary lock information and unlocking personnel information, selects to generate auxiliary locks, and sends them to the computer key; at the same time, it saves the unlocking records uploaded by the key for browsing and querying; the auxiliary lock information is authorized according to the device type, electrical wiring diagram and room geographical distribution.
[0015] The auxiliary control lock is also equipped with an anti-error lock. The interfaces of the anti-error lock and the auxiliary control lock adopt a unified design and hierarchical configuration, so that the anti-error key can open the anti-error lock and the auxiliary control lock, and the auxiliary control key can only open the auxiliary control lock but not the anti-error lock. Only one anti-error key is needed to open the anti-error lock and the auxiliary control lock.
[0016] The anti-error key adopts an arc-shaped key embryo, a tooth shape with a layered curve structure, and a hidden strong magnetic element.
[0017] The substation lock management system and method operate in a coordinated manner through a single-station mode and a centralized control mode. In the single-station mode, the workstation stores information and generates an unlocking sequence, which is transmitted to the computer key via a data transmission charging station connected to Bluetooth. The code reading module of the computer key reads the unique identification code of the auxiliary control lock to unlock the lock, and the hierarchical lock cores of the equipment in different areas ensure the locking function. In the centralized control mode, the centralized control center, the sub-control center and the substation are connected through an optical fiber channel to achieve hierarchical centralized control management. The auxiliary control lock can be transmitted through local and remote modes, and the remote SMS mode is convenient for on-site operation. The host records the unlocking information and can be queried, and the auxiliary control lock information is graphically displayed and classified and stored. The system reserves an interface that can be linked with other systems. The management method includes authorized unlocking, designated unlocking and cross-application modes to meet the needs of different scenarios. The operation ticket can be authorized at different levels, and the host stores the auxiliary control lock and unlocking personnel information and authorizes it in a specific way. The auxiliary control lock is equipped with an anti-mistake lock, and the anti-mistake key is specially designed to ensure safety. The entire system realizes efficient and safe management of substation locks through the synergy of multiple methods.
[0018] Compared with the prior art, the present invention has the following beneficial effects: The single-station mode is combined with the centralized control mode to achieve top-down hierarchical centralized control management. The centralized control center can manage the auxiliary control locks of all substations, the sub-control center manages the substation locks under its jurisdiction, and the substation manages the locks of its own station. The clear division of management authority makes management more orderly and efficient.
[0019] The transmission modes of auxiliary control locks are flexible and diverse, including local workstation and remote network and SMS mode. In SMS mode, operators can receive unlocking sequences and send operation information on site without returning to the centralized control center, which greatly improves work efficiency.
[0020] The code reading module of the computer key reads the unique identification code of the auxiliary control lock. The unlocking function can only be realized when the identification code matches and has the unlocking sequence, ensuring the accuracy and safety of unlocking.
[0021] Different graded lock cores are installed on equipment in different areas to achieve refined locking functions and improve the safety of the equipment.
[0022] The auxiliary control lock is equipped with an anti-misoperation lock. The interfaces of the anti-misoperation lock and the auxiliary control lock adopt a unified design and hierarchical configuration. The anti-misoperation key can open the anti-misoperation lock and the auxiliary control lock, while the auxiliary control key can only open the auxiliary control lock, which improves the safety of operation and avoids misoperation. The anti-misoperation key adopts an arc-shaped key embryo, a layered curved structure of teeth, and a hidden strong magnetic element, which increases the safety and uniqueness of the key and makes it difficult to copy and illegally use.
[0023] The host records detailed data such as the unlocking person, unlocking time, unlocking device information, etc., which can be queried through a variety of retrieval methods. At the same time, the computer key also saves the unlocking record recall data and the user cannot delete it, ensuring the integrity and security of the record, providing a strong basis for subsequent auditing and management.
[0024] Relevant information of devices in different regions is stored in the host, including device name, lock code, geographic location, associated device information, etc., and is directly displayed on the software interface in a graphical form. Devices are classified according to geographic location, device voltage level, device type and user usage habits, making the information more intuitive and easy to manage.
[0025] The system reserves communication interfaces for the anti-mislocking system and the substation auxiliary control system, which can be linked with the video surveillance system and the access control and anti-theft system in the later stage, providing the possibility for the expansion and upgrading of the system and further improving the safety and management efficiency of the substation.
[0026] The management methods include authorized unlocking mode, designated unlocking mode and cross-application mode. Operators can choose the appropriate mode to operate according to the actual situation. If the authority allows, the centralized control center, sub-control center or substation can issue an operation ticket for authorized operation ticket to meet various on-site unlocking needs.
