Wireless distributed type system for guiding against error closedown includes host for guiding against five operations, and at least one computer key. Characters are that lock system also includes main station of blue teeth, and at least one base station. Main station of blue teeth is connected to the said host. Being connected to each other through communication media in series, each base station is connected to main station of blue teeth. Wireless data exchange can be carried out between each base station and computer key in covered area. Using blue teeth technique, the invention realizes wireless digitized communication to guarantee data exchange in real time between the computer key and the host. The key can feedback information operated back to the host in time.
Description
Technical field
The present invention relates to electric power system anti-misoperation locking technical field, the particularly a kind of dispensing power plant error proof locking system of microcomputer of station such as power plant or power station that are applied to for preventing that misoperation from using.
Background technology
At present, dispensing power plant uses very extensive in the station error proof locking system of microcomputer in power plant or power station etc., development also relatively rapidly, though the product of each producer respectively has its characteristic, but the technological means of basic principle and employing is roughly the same, and device mainly is made up of artificial intelligence screen, industrial computer, computer key and various lockset (combination padlock).By simulation examination operation on the artificial intelligence screen, by logic rules of storing in advance in the industrial computer and state per step operation is judged, and operating procedure is imported in the computer key by the serial line interface communication, open the coding lock that is loaded on the on-the-spot relevant device by computer key then, carry out grid switching operation.The superiority of this kind error proof locking system of microcomputer is: easy to operate, safeguard that simple, dependable performance, cost are relatively low, but because its critical piece---computer key can not with other part real-time exchange data (state) in field apparatus and the system, and make its anti-error function and scope be subjected to very big restriction, can't satisfy accident conditions and maintenance during prerun anti-error needs and have no alternative but use the emergency release of no any anti-error function, move to electric power safety and bring very big hidden danger.Must depend on artificial state in course of normal operation checks, not only brought overcharge to the user of service, and owing to be subjected to the influence of subjective factor, the reliability of its locking is subjected to very big influence, too because data can not real-time exchange, brought heavy burden for the lock operation of large-scale substation (booster stations), can't realize the parallel work-flow of the same task of many groups, need the overspending operating time for complex operations, make the operating efficiency step-down, interruption duration elongates, thereby makes the application of microcomputer locking be subjected to certain restriction.
Summary of the invention
Technical problem to be solved by this invention is that wireless distributed anti-error locking system of the present invention can guarantee that the operational outfit state information can pass to five anti-main frames, the real-time of enhanced system in real time.
Technical problem to be solved by this invention is achieved by the following technical solution: a kind of wireless distributed anti-error locking system, it comprises five anti-main frame and at least one computer key, it is characterized in that this block sytem also comprises bluetooth main website, at least one base station; This bluetooth main website and five anti-main frames are connected, connect with communication media between each base station and are connected in the bluetooth main website, and wireless data exchange can be carried out with the computer key within its coverage in each base station.
The wireless distributed anti-error locking system of the present invention uses state-of-the-art technology-" bluetooth " technology of short-distance wireless communication, realize the wireless digital communication, guarantee to carry out the real time data exchange between computer key and the five anti-main frames, computer key can in time return operation information to main frame, make things convenient for host-tracking to handle, effectively improved real-time, the reliability of existing system.
Description of drawings
Fig. 1 is the wireless distributed anti-error locking system overall structure of the present invention figure;
Embodiment
Referring to Fig. 1, a kind of wireless distributed anti-error locking system, it comprises five anti-main frames and to a plurality of computer keys, in addition, this block sytem also comprises bluetooth main website, simulating display screen, Internet/Modem network system and a plurality of wireless base station; This bluetooth main website and five anti-main frames are connected, connect with communication media between each wireless base station and are connected in the bluetooth main website, and wireless data exchange can be carried out with the computer key within its coverage in each base station; This network system can reach Internet or local area network (LAN) with five anti-main frame internal informations.
The physics formation of this network mainly comprises several sections such as wireless main website (bluetooth main website), wireless base station (radio relay communication device), wireless terminal (computer key), network management.Network topology structure is a centric topology.The bluetooth main website serves as central station, and the visit of all base stations or terminal (computer key) is controlled by it.In the zone that network covered, mark off many honeycombs or sub-district, set up a wireless base station in each sub-district, upwards adopt dedicated channel to link to each other, adopt common signal channel and wireless terminal communication downwards with wireless main website, thus the effect of playing the signal relay, expanding the coverage area.Different networks can be decided according to the geographical situation of network environment (transformer station or power plant), generally adopts comprehensive coverage mode.The principle that wireless base station (relay stations) distributes is: should cover the maximum planes space as much as possible, interior friendship or the overlapping minimum that reaches that this covering is produced.
The wireless distributed anti-error locking system of the present invention uses state-of-the-art technology-" bluetooth " technology of short-distance wireless communication, realize the wireless digital communication, guarantee to carry out the real time data exchange between computer key and the five anti-main frames, computer key can in time return operation information to main frame, make things convenient for host-tracking to handle, effectively improved real-time, the reliability of existing system.
The present invention also has some other distortion or improvement.Advantages such as for example, it number is 200520060208.9 computer key that Chinese patent application is adopted in this invention, and this computer key unlocking mechanism is held formula for pincers, and it is big that it has the moment of unblanking, energy-conservation.If those skilled in the art are subjected to the change or the improvement of the conspicuous unsubstantiality that inspiration of the present invention makes, all belong to the protection range of claims of the present invention.
Claims (5)
