Technical field
The invention belongs to equipment management fields, and in particular to a kind of confined space operation prevents the braking wrong-mounting prevention of maloperation
It sets and control method.
Technical background
The connecting pipe system of confined space equipment electronic, pneumatic and manually-operated gate is in electricity power enterprise or other enterprises
Xegregating unit, there is fearful misoperation fault hidden danger for such separation valve door.Lead to especially in running equipment or system
When the confined space upkeep operation that the valve closing that reaches a standard door has isolated, if overhauled in defect elimination operation process in service personnel, fortune
Maloperation, the accidentally behaviors such as Open valve occur for administrative staff, and consequence is unimaginable, easily causes the pernicious personal injury thing of operating personnel
Therefore.
3 everybody body death major accidents that 23 days 2 months Chang Mount steam power plants of Jilin songyuan in 2016 occur are exactly because of artificial mistake
It operates and leads to confined space operating personnel's injures and deaths.Therefore, for the frequent operation defect elimination of thermal power plant and constitute confined space operation,
In the presence of the equipment of similar risk, confined space safety device for operation is researched and developed, realizes and forces locking, to reducing or eliminating electricity
Factory's similar accident, the safety of effective protection confined space operating personnel improve power plant's operational safety managerial ability, have very heavy
The meaning and practicability wanted.
Summary of the invention
For the above technical problems, the present invention, which provides a kind of confined space operation, prevents the braking of maloperation anti-error
Device, comprising: the confined space operation prevents the safety arrestment error-proof device of maloperation, comprising: display, face recognition system
System, work card, work card storage device, controller and electric-controlled switch；
The confined space safety device, i.e., for controlling the route of the valve power supply connected in the confined space,
Power supply line for controlling confined space equipment valve switches on and off；
The facial-recognition security systems are connect with controller, for recording or identifying the service personnel into confined space operation
Facial characteristics data, with determine enter confined space operation service personnel identity information and be sent to controller；
The display is mounted in the security protection control cabinet, is connect with controller, for showing the safety system
The working condition of dynamic error-proof device；
The work card is accommodated in work card storage device, or is held by service personnel；The work card has several, is
Specification same electromagnetic card；
The work card storage device is mounted in the control cabinet, is connect with controller；The work card storage device
The card slot of the work card is stored with several；The card slot have electric magnetic card detection function, for identification in card slot whether
It is accommodated with work card, and is notified in controller；
The electric-controlled switch has several, and the valve power supply line being series in confined space control system respectively is used for
Control switching on and off for each valve power supply line；
The controller is mounted in the control cabinet, is connect with each electric-controlled switch, each automatically controlled for controlling
The opening and closing of switch switches on and off control to the power supply of each confined space control system inner valve to realize.
When the confined space equipment valve is electrically operated valve, confined space equipment valve is controlled by the braking error-proof device

A kind of confined space operation prevents the control method for braking error-proof device of maloperation, is made using the above-mentioned confined space
Industry prevents the braking error-proof device of maloperation, comprising the following steps:
Step 1, need the service personnel into the confined space be 1 or several, when service personnel's scheduled overhaul equipment,
The work ticket for recording maintenance content is submitted to operations staff；Operations staff is connected to work ticket and does the confined space according to maintenance content
Quarantine measures close respective valves according to the action of work ticket, and cut off the power supply line of these valves；
Step 2, after the completion of running quarantine measures, operations staff signs work ticket, and service personnel can go into operation, run at this time
Personnel successively send out work card to each service personnel and carry out face recognition, the face identified by facial-recognition security systems
Portion's profile input controller；If operated successfully, controller control display shows " face recognition success " printed words, no
Then show " face recognition is unsuccessful " printed words, which re-starts face recognition, until display shows " face recognition
Success " printed words；
After carrying out successful face recognition at least once, controller controls electric-controlled switch and disconnects；
Step 3, each service personnel takes away from work card storage device and carries a work card；The work card is received
Receive device by its work card storage situation real-time transmission in controller, so that controller is judged the case where work card is removed；Control
Device control display processed shows number in position corresponding with work card；When work card is not removed, which is 0；Work as work
As board have 1 be removed when, the number be 1, there are 2 boards to be removed, the number be 2, and so on, which, which also indicates that, is having
Limit service personnel's quantity of operation in space；
When any work card is removed, controller controls electric-controlled switch and disconnects；
Step 4, it after service personnel completes service work, after all leaving the confined space, returns at operations staff
Handling service work terminates to close work ticket, and each service personnel carries out face recognition by facial-recognition security systems at this time, and will
Its facial characteristics data input controller identified；
Step 5, if the facial characteristics data of input controller matches with identity information obtained in step 2, table
Show and operate successfully, controller control display shows " face recognition success " printed words；Otherwise, " face recognition is unsuccessful " word is shown
Sample, the service personnel re-start face recognition, until display shows " face recognition success " printed words；
Step 6, if in step 5 the facial characteristics data of input controller all with identity information obtained in step 2
Match, then it represents that all service personnel all leave the confined space back to safety zone, and controller control display is shown
" face recognition all successes " printed words, enter step 7；If the facial characteristics data of input controller is not all and in step 2
Obtained identity information matches, then it represents that operates unsuccessful, return step 4；
Step 7, service personnel is by the empty calorie slot of the work card respectively held insertion work card storage device, until whole works
Making board, all storage is to work card storage device, and then controller is connect by the power supply line that electric-controlled switch controls each valve
It is logical；
Its work card storage situation real-time transmission in controller, is made controller judgement go to work by the work card storage device
Make the recovering state of board；When the work card of corresponding position is not inserted into reset, which is not 0, shows that still someone is limited
In space；Only whole work card corresponding positions are entirely insertable reset, which is 0；
Step 8, operations staff opens respective valves recovery confined space system investment fortune according to the action of work ticket
Row.
