Abstract
The invention discloses a transformer substation device maintenance safety monitoring system and method. The system adopts non-contact human body induction and wireless transceiving signal technologies. When a person approaches a device which needs to be monitored, the system carries out automatic verification on the identity of the person and makes a corresponding action and if the identity verification is successful, a camera is started to record videos of a work project, or a database takes corresponding measures of alarm check and the like so as to prevent non-maintenance personnel from approaching a dangerous device and prevent maintenance personnel from personal injuries caused by finding of a wrong target device. The database allocates operation permission electronic certificates to maintenance personnel who already obtain work tickets or operation tickets and the maintenance personnel can only enter specific allowed areas to work when wearing the operation permission electronic certificates and can maintain a device only after fingerprint verification. The transformer substation device maintenance safety monitoring system and method have the advantages of being high in spontaneity, accurate in monitoring, high in safety coefficient, reasonable in design, simple and convenient to operate and high in performance cost ratio so that the security of devices and maintenance personnel is ensured.
Description
Technical field
The present invention relates to a kind of substation equipment maintenance safety supervisory system and method.
Background technology
Along with the develop rapidly of electric power enterprise, electric service work has also obtained significant progress, particularly power supply reliability significant raising.The life security that a lot of potential safety hazards seriously threaten personnel in power station, preventing that unrelated person from approaching aspect certain hazardous equipment, at present normal employing hung nameplate and installing and the measure such as blocked, but this passive safeguard procedures still cannot avoid the misconnection of human factor near; And occurring also there is no corresponding measure after personal safety accident, may cause more major break down.
At present, substation equipment maintenance has two kinds of modes: while 1, there is equipment failure, overhaul immediately; 2, periodic maintenance maintenance and scheduled overhaul.The necessary relevant inspection standard of strict implement of substation equipment maintenance and workflow, guarantee equipment and personal security.Substation equipment maintenance must be followed work ticket system, work permit system, work supervisory institution and work interruption, transfer and termination system.Although institutional improvement, because electric system is in large scale, complicated operation, also there will be unexpected safety problem, all device damage and human casualty accident can occur every year.One of them main cause is to have occurred mistake between site examining and repairing operating process and the plan flow process of scheduling He Yunjian department, and this is relevant with complicacy, the subjectivity of site examining and repairing work, also relevant not alternately with on-the-spot and scheduling, Yun Jian department.In a word, this area needs the urgent problem solving of technician to be at present: by the means of robotization, the maintenance personal of hazardous equipment is carried out to authority recognition, flow process control, operation note and management, try to avert accidents, improve the safety management level of overhaul of the equipments comprehensively.
Generally speaking, need at present the urgent technical matters solving of those skilled in the art to be: to hazardous equipment maintenance personal, to carry out authority recognition, record and management, prevent that misconnection is near, and start cascading trip mechanism when there is personal injury, improve personal safety management level.
Summary of the invention
Object of the present invention is exactly in order to address the above problem, and a kind of substation equipment maintenance safety supervisory system is provided, the identification automatically of this system, automatic monitoring, auto-alarming, automatic linkage tripping operation when accident occurs; It has advantage real-time, that monitoring is accurate, safety coefficient is high, reasonable in design, easy and simple to handle, cost performance is high.
To achieve these goals, the present invention adopts following technical scheme:
A substation equipment maintenance safety supervisory system, comprises sensing unit, information acquisition unit, identity authenticating unit, image unit, alarm unit, electronic lock and hand-held set; Wherein,
