Description
Technical field
The present invention relates to a kind of electronic lock, be specifically related to a kind of coded lock.
Background technology
Traditional coal mine switch maintenance generally is that the maintainer draws back switch higher level's isolation switch, places a warning sign simultaneously at the switch place, goes to carry out the circuit service work.Occur warning sign sometimes and be not intended to put away by other staff, perhaps other staff do not see the situation of warning sign.If under above-mentioned condition, other staff split to close and close a floodgate, and will constitute great threat to maintainer's safety.This has just brought certain potential safety hazard.
According to the statistics that national coal mining accident is in recent years analyzed, the dynamo-electric accident in colliery in roof accident, gas accident, shipping accident, blow out after the accident, occupy the 5th.The dynamo-electric accident in colliery refers to the accident that electromechanical equipment (facility) causes, and comprises the accident that consumer takes place in installation, maintenance, debug process, occurs in low, high-voltage fence, the accident of human electric shock of direct current trolley line etc.Particularly in the coal mine switch maintenance process, in maintenance, split the pass owing to carelessness and carry out closing operation, this safety to the maintainer has constituted great threat.
Need a kind of safe-guard system that the maintainer is had more safety guarantee in the power system of colliery.
Summary of the invention
The objective of the invention is to, a kind of code lock for coal mine switch maintenance of the company of providing can effectively prevent the generation of false switching situation, has effectively ensured colliery maintainer's safety, has simple in structure, advantages such as cost is low, dependable performance simultaneously.
The technical problem that the present invention solved can adopt following technical scheme to realize:
Code lock for coal mine switch maintenance; Comprise a coding lock system, said coding lock system comprises a microprocessor system, and said microprocessor system connects a display, a keyboard; It is characterized in that; Also comprise a power switch system, said power switch system is provided with the anti-combined floodgate module that a pair of closing operation blocks, and said anti-combined floodgate module is provided with an anti-switching signal input;
Said coding lock system comprises a control signal output, and said control signal output connects said anti-switching signal input.
In the above-mentioned design, no longer simply through warning sign passive to other staff caution, but the form through coded lock initiatively limits other staff and carries out closing operation.The maintainer had more effective safety guarantee.This code lock for coal mine switch maintenance not only can provide good safety guarantee to the colliery maintainer, also can good safety guarantee be provided for other maintainers.Such as good safety guarantee being provided for iron ore maintainer, tunnelling maintainer etc.
Said power switch system comprises the contactor of a control power circuit break-make, and the contactor coil of said contactor connects supply line through the Chang Kaiduan of a relay; The electromagnetic coil of said relay is connected supply line through a switch knob with anti-combined floodgate module.This design is comparatively simple and reliable.
When the signal that the output of the control signal output of coding lock system prevents to close a floodgate, anti-combined floodgate module receives this signal through anti-switching signal input, breaks off the circuit of being controlled.Said relay is not controlled by switch knob, and the Chang Kaiduan of relay is in off-state, and then the power circuit that the power switch system is controlled is in off-state, and does not allow to close a floodgate, thereby has ensured maintainer's safety effectively.
After starting coding lock system, the demonstration maintenance menu whether the microprocessor system proceeds to be provided with through display display alarm staff; Said microprocessor system controls said keyboard and is in selection and whether proceeds to be provided with function;
Selecting through said keyboard is when proceeding to be provided with, and the microprocessor system shows the password setting menu that encrypted message is set through display; Said microprocessor system controls said keyboard and is in the password setting function;
After password setting was accomplished, coding lock system locked, and controlled the anti-"on" position of said anti-combined floodgate module entering, and closing operation is blocked; The microprocessor system shows the release menu through display simultaneously; Said microprocessor system controls said keyboard and is in unlocking function, after the password of the above-mentioned setting of input, accomplishes release, password inefficacy simultaneously; Said anti-combined floodgate module withdraws from anti-"on" position, allows to carry out closing operation.
Password in the above-mentioned design is set up on their own by maintainer or other staff, and password ceases to be in force automatically after each release.Effectively avoid the problem that other staff carry out release in the maintenance, further ensured maintainer's safety.Operating procedure of the present invention is simple, can effectively save time for the staff.
Store the high grade cryptosystem that is provided with in advance in the said microprocessor system; Under the coding lock system locking state; After importing said high grade cryptosystem through said keyboard, accomplish release, the password that is provided with of staff lost efficacy simultaneously; Said anti-combined floodgate module withdraws from anti-"on" position, allows to carry out closing operation.
Forget the staff under the situation of set password, perhaps forget release, and during from the release in time of work reason, the related personnel can carry out release through high grade cryptosystem the staff.In order to avoid influence operate as normal.
