Description
The utility model relates to a kind of electric operation anti-misoperation locking device, belongs to the electrical safety opereating specification.
Known in the past method is mechanical anti-misoperation locking and electromagnetism anti-misoperation locking device, the former complicated in mechanical structure, operation inconvenience, and latter's wiring is a lot of, and the two tapered end dead problem of becoming rusty is serious; Utility model patent (CN2042642U) provides a kind of computer mechanical locking device, and its tapered end still prolongs uses common tapered end, and the dead problem of becoming rusty does not solve; The coded system of binary format is difficult for manually recognizing to be read with computer fault-tolerantly, and reliability is low; The switching manipulation situation is feedback not, and five tight anti-measures can not get implementing.
The purpose of this utility model provides a kind of electric operation monitor device, and the locking misoperation prevents the generation of misoperation, improves the fail safe of electric operation.
Feature of the present utility model is to comprise monitoring robot and coding lock;
The monitoring robot comprises single-chip microcomputer, memory, vision device, sound-compound-circuit, locking actuator, key, isolation serial port, display circuit, power supply, back-up source and booster power; Its connecting relation is: the output of vision device connects the IO input port of single-chip microcomputer, and the single-chip microcomputer delivery outlet connects sound-compound-circuit, locking actuator and display circuit; Locking actuator includes key, coil and moving armature; Single-chip microcomputer links through isolating serial port and its machine; All chips, back-up source and booster power are all battery-powered, and back-up source is powered to data storage; The output of the controlled termination single-chip microcomputer of booster power, output is outer confession after transformer isolation;
The coding lock comprises encoding board and lock body; Lock body includes and horizontally inserts, latch and indicator light; Indicator light is through the auxiliary contact of current-limiting resistance serial connection switch; The long number coding is arranged on the encoding board; Encoding board is fixed on the lock body as the coding of locking; The encoding board list is used as the order plate;
Coding on the encoding board adopts the digital coding of multidigit decimal, is aided with boot section, check field and self check district; The vision device can be photosensitive tube, hall device or magnetosensitive part, and they are pressed single file and arrange, and the scanning received code is accepted coding with 3 when numeral vertically scans; When digital transversal scanning, accept coding with 5; There are a bullport or septated hole in the other boot section of coding, and corresponding vision device increases a guiding tube or separating tube; By guiding tube synchronously or to cut apart the area under control other, recognition coding input single-chip microcomputer is again by reaching decimal-coded purpose after the identification of single-chip microcomputer group code; The other check field of coding has a bit parity check hole, and corresponding vision device increases a calibrated tube;
Switch open status indicator lamp and switch closed condition indicator light are connected in series driving auxiliary contact and closing auxiliary contact of switch respectively; After being received by the vision device, light is connected to the input port of single-chip microcomputer; The supply voltage of lamp is supplied with for high voltage source by on-the-spot or the outer of monitoring robot greater than 30 volts;
The stainless dead, stuck of coding lock is crucial, is the key that can whole device be promoted, and for this reason, coding lock material is a rush-resisting material: stainless steel, synthetic resin or fiberglass; Perforate on the lock body is horizontal perforate or STH, and the hole is circular; The part that includes in the hole is cylindrical or half-cylindrical; Hook is made of two cylinders of decentraction, the cylinder that draws outward up, inner cylinder below, the movable part position on it is lower than the outer cylindrical lower edge that draws; Oil-filled in the lock body; In lock body or horizontal the inserting circulating oil path is arranged; The sectional area of circulating oil path is less than horizontal slotting sectional area; The coding of order on the plate is one group of character or numeral of showing with 7 segment tables of agreement in advance; The coding lock is installed in by the handle of switch.
The step of monitoring is to receive the operation order that its machine is sent here by serial port, and memory is hung in and encodes when locking in internal memory, vision device scanning tapered end coding; During by the self check district, whether the automatic inspection sensing part is intact; Debate not by single-chip microcomputer behind the coding input single-chip microcomputer, the current state of identification switch again after putting in place, if consistent in code-locked and on off state and the memory, then drive blocking mechanism and discharge key, and verbal cue is unblanked, key promptly can move freely, and keyhole is just in time aimed in the position, by manually key being stretched into keyhole, screw key is opened tapered end, carries out electric operation, after finishing tapered end is locked, return key, after the monitoring robot monitors that key is returned and the vision device experiences electric operation and finish, then drive next step program and verbal cue.Tapered end, key and monitoring robot guarantee that by cooperatively interacting on the machine tapered end locks, and key is returned monitoring and could be taken off from locking behind the robot, as long as this adopt, and general do not get down from horse that method can be finished.Demonstration can be adopted liquid crystal display, and that joins realizes in bulb, so that save electric weight.Usually, the recognition result that shows code-locked; After receiving order, also can show the numbering that next step wants operating equipment, so that accelerate the speed of accident treatment.After operation was finished, robot was sent to its machine with operating result by the serial port monitoring, to add up and to evaluate this operational circumstances and keep existing on off state.
Adopt above technical scheme, the coding lock construction is simple, and drawback such as it is dead, stuck to avoid becoming rusty reaches antirust, rainproof, moistureproof, the purpose of preventing dust; The circulation oil duct of design is first to the cushioning effect of having unblanked, and second forced oil is sprayed on each movable part, plays lubricated effect; High pressure on the auxiliary contact helps to overcome corrosion resistance and loose contact phenomenon; The decimal number of multidigit coding manually recognize read with machine recognize read unified; Usually can adopt three circuit breaker encoded, the end increases by one to distinguish with circuit breaker, isolating switch, ground connection disconnecting link, fence gate and protection fling-cut switch at interval, head end increases by one with the difference different substation, with unified operation and the unified maintenance that adapts to unattended station; How much irrelevant what and vision device of coding figure place be; The on off state isolated feedback is to guarding robot, thereby constitutes perfect operation monitoring; Stand-by power supply is given the data storage continued power, to guarantee can to change battery in the middle of the operation.
According to top technical scheme, can design multiple embodiments, just guard robot below, the coding lock respectively provides a kind of embodiment.
