Description
Technical field
The present invention relates to a kind of substation equipment maintenance safety monitoring system and method.
Background technology
Along with developing rapidly of electric power enterprise, electricity service work also achieves significant progress, particularly power supply reliability significant raising.A lot of potential safety hazards seriously threaten the life security of personnel in power station, and preventing unrelated person close in certain hazardous equipment, at present frequently with hanging nameplate and installing such as blocks at the measure, but the misconnection that this passive safeguard procedures still cannot avoid anthropic factor is near；And also without corresponding measure after there is personal safety accident, it is possible to more major break down can be caused.
At present, substation equipment maintenance has two ways: when 1, there is equipment fault, overhaul immediately；2, periodic maintenance maintenance and scheduled overhaul.The necessary relevant inspection standard of strict implement of substation equipment maintenance and workflow, it is ensured that equipment and personal security.Substation equipment maintenance must comply with work ticket system, work permit system, work supervisory institution and work and is interrupted, shifts and termination system.Although institutional improvement, but owing to power system is in large scale, complicated operation, there is also unexpected safety problem, all can there is device damage and human casualty accident every year.One of them main cause be site examining and repairing operating process and scheduling and Yun Jian department planning procedures between occur in that mistake, this with site examining and repairing the complexity of work, subjectivity relevant, also with on-the-spot with scheduling, Yun Jian department mutual relevant not.In a word, current this area needs the problem that technical staff urgently solves to be: by the means of automatization, the maintainer of hazardous equipment is carried out authority recognition, Row control, operation note and management, try to avert accidents, improve the safety management level of overhaul of the equipments comprehensively.
Generally speaking, it is presently required one that those skilled in the art urgently solve technical problem is that: hazardous equipment maintainer is carried out authority recognition, record and management, prevent misconnection near, and start cascading trip mechanism when there is personal injury, improve personal safety management level.
Summary of the invention
The purpose of the present invention is contemplated to solve the problems referred to above, it is provided that a kind of substation equipment maintenance safety monitoring system, and this system can identify automatically, monitoring automatically, auto-alarming, when accident occurs, automatic linkage trips；It has real-time, monitoring accurately, safety coefficient high, reasonable in design, advantage that easy and simple to handle, cost performance is high.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of substation equipment maintenance safety monitoring system, including sensing unit, information acquisition unit, identity authenticating unit, image unit, alarm unit, electronic lock and hand-held set；Wherein,
Described sensing unit, including several human body sensors being arranged at around on-the-spot power equipment and work permit electronics card induction apparatus, described human body sensor, with information acquisition unit communication, for gathering human body signal, identify and enter power equipment periphery with or without personnel, adopt non-contact inductive technology, regulate its detection range according to different power equipments；
Described work permit electronics card induction apparatus, with information acquisition unit communication, the work permit electronics worn for sensing maintainer is demonstrate,proved；

Described identity authenticating unit, receives the information of signal gathering unit, and alarm unit one-way communication, for contrasting, verify the information of information acquisition unit and database purchase, it is achieved the identity of maintainer, purview certification；
Described image unit, is connected with human body sensor, for the image of monitoring electrical equipment periphery, it is ensured that equipment safety；
Described electronic lock, is installed on equipment, coordinates with hand-held set, compares with the current operation object of hand-held set, and when comparison result is consistent, electronic lock is opened；
Described hand-held set, is positioned over each transformer station, and identity authenticating unit communication, has fingerprint identification function, have recorded maintenance people, authority, maintenance object and flow process, repair process is carried out voice message；
Described alarm unit, and information acquisition unit communication, it is used for sending sound and light alarm.
Described work permit electronics card is for contactless electronic card sheet equipment, and this equipment is provided with SOS button, this device storage personal information and operation information.
A kind of operational approach adopting above-mentioned substation equipment maintenance safety monitoring system, it specifically comprises the following steps that
(1) Work Authorization is obtained: electric power overhaul service centre provides work permit electronics card to maintainer, and writes maintainer information in work permit electronics is demonstrate,proved and need the information of operation equipment, and two information are simultaneously entered data base；
(2) infomation detection: maintainer enters transformer station, after obtaining hand-held set, close to maintenance of equipment, human body sensor has detected whether around personnel's access arrangement, whether work permit electronics card induction apparatus detection entrance personnel hold work permit electronics card, and image unit works；
(3) cross-check information: the information existed in the identity authenticating unit information and date storehouse to detecting carries out comparison and detection, if checking is correct, identity authenticating unit sends signal, and hand-held set prompting maintainer carries out fingerprint verification；
(4) fingerprint verification: hand-held set reminds entrance personnel, and hand-held set is inserted in electronic lock by entrance personnel, presses fingerprint, carries out fingerprint recognition, fingerprint is authenticated；
(5) authority is authorized: if fingerprint is correct, electronic lock is opened, and maintainer carries out associative operation, and alarm unit is failure to actuate, otherwise, alarm unit action；
(6) keep in repair: electric power overhaul service centre sends relevant maintenance flow, points for attention by identity authenticating unit to hand-held set, and maintainer completes maintenance task according to flow process and standard criterion；
(7) fingerprint notice: after maintainer has worked, again press fingerprint, all devices returns original state.
In described step (1), obtain work permit authorization and be divided into two kinds:
(I) regular situation: maintainer is carried out task allocation by data base, authorizes while step (1) completes；
(II) emergency: maintainer needs to obtain Work Authorization at the scene temporarily, it is operated remote authorization, maintainer sends authorization requests by personal communication apparatus to data base, if request is allowed to, data base sends the maintainer personal information of working region control room device authentication, job information and Permission Levels to personal communication devices, maintainer fills in authorization message in the control room of working region, controlled indoor equipment by working region to authorize to the held work permit electronics card of maintainer, and record mandate time and authorization message.
