Detailed Description

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

For easy understanding, referring to fig. 1, an embodiment of a method for checking a status of a switch cabinet provided by the present application includes:

step 101, acquiring various switch cabinet state information of a switch cabinet, wherein the switch cabinet state information comprises a circuit breaker auxiliary contact state, a valve baffle state, a handcart stroke position, a secondary aviation plug state, a grounding switch state, a circuit breaker operation and energy storage power supply air switch state and a tripping outlet pressing plate state.

Multiple different states can be obtained to a plurality of positions of cubical switchboard, and seven cubical switchboard state information have been selected for the state of discerning the cubical switchboard that can be more accurate to this embodiment, breaker auxiliary contact state, valve baffle state, handcart stroke position, secondary aviation plug state, earthing switch state, circuit breaker operation and energy storage power air switch state and tripping operation export clamp plate state promptly.

The state of the auxiliary contact of the circuit breaker comprises closing and opening; the valve baffle state comprises an effective opening position, an effective closing position and a poor closing position; the handcart stroke position comprises a handcart working position and a test/separation position; the secondary aviation plug state comprises a plug inserting state and a plug pulling-out state; the states of the grounding switch comprise an effective open position, an effective closed position and a bad open and closed position; the breaker operation and energy storage power supply air switch states comprise an energy storage power supply input state and an energy storage power supply exit state; the trip outlet pressure plate state includes an engaged state and an disengaged state.

And 102, coding the state information of the switch cabinet by adopting binary coding to obtain a state coding sequence.

The coding aims at selecting all seven kinds of switch cabinet state information, and coding each kind of switch cabinet state information into 0 or 1, so that a state coding sequence formed by all switch cabinet state information is obtained, and the state coding sequence comprises 7 bits in total. The valve baffle state only encodes the effective open position and the effective closed position in the encoding process, and the grounding switch state also encodes the effective open position and the effective closed position. The poor closure position or poor deciliter position is an expression of the image recognition stage. The overall coding results can be seen in table 1.

The state information of the switch cabinet is obtained every time and is coded to obtain a determined state coding sequence, namely, each type of switch cabinet state information is only one determined state, for example, 0011100, the state indicates that the state of the auxiliary contact of the circuit breaker in the switch cabinet state information at the moment is opening, the state of the valve baffle is effective opening, the travel position of the handcart is a working position, the state of the secondary aviation plug is a plug insertion state, the state of the grounding switch is effective closing, the state of the circuit breaker operation and the air switch of the energy storage power supply is energy storage power supply quitting, and the state of the pressure plate at the tripping outlet is quitting.

And 103, identifying the valve baffle state and the grounding switch state by adopting a time scale image identification method to obtain an identification result.

Further, step 103 includes:

acquiring a valve baffle time label chart and a grounding switch time label chart corresponding to the valve baffle state and the grounding switch state;

and identifying the valve baffle time mark graph and the grounding switch time mark graph based on a preset time mark image identification method to obtain an identification result.

The method comprises the steps of accurately identifying the valve baffle and the grounding switch by using an image with a time scale, and determining the state degrees of the valve baffle and the grounding switch, namely, a bad closing position, a bad opening and closing position and the like. The valve baffle time mark graph and the grounding switch time mark graph are obtained while the state information of the switch cabinet is obtained. The on/off state of the main contact of the earthing switch is identified based on the image.

And step 104, comparing and checking the state coding sequence and the recognition result with a reference state sequence and a reference recognition result in a preset switch cabinet state library respectively, if the comparison results are consistent, checking the state coding sequence and the recognition result, and if not, sending an error code alarm prompt and locking the operation.

The comparison process of the state coding sequence is the comparison process of binary bits, if the numerical value of each bit is the same, the states are consistent, otherwise, the checking fails; for convenience, the obtained recognition result can be converted into a numerical format for visual comparison, for example, the combination bit is 1, the separation bit is 0, and the bad closure bit is 2; the specific conversion can be selected according to actual situations, and is not limited herein.

Further, the construction process of the preset switch cabinet state library is as follows:

acquiring various historical switch cabinet state information of a switch cabinet;

and constructing the states of the switch cabinet under different preset operation states according to the historical state information of the switch cabinet to obtain a state library of the switch cabinet, wherein the preset operation states comprise a running state, an overhaul state, a hot standby state and a cold standby state.

The maintenance state in the preset operation state can be an outgoing line maintenance state, a switch maintenance state and a simultaneous occurrence and switch maintenance state; and the cold standby state comprises the test state. Under different operation states of the switch cabinets, the state expressions of the switch cabinets are different, and 6 operation states are listed in total, wherein when the switch cabinets are in an operation state, the switch cabinets are in the state when a circuit breaker 1, a handcart 1, a grounding switch 0, a valve baffle 0, a secondary aviation plug 1, a tripping outlet pressing plate 1 and a circuit breaker operate and energy storage power supply 1, the state code is 1100111, and images with time marks and image recognition results are associated; when the switch cabinet is in an outgoing line maintenance state, the switch cabinet is in the state when the circuit breaker 0, the handcart 0, the grounding switch 1, the valve baffle plate 1, the secondary aviation plug 1, the tripping outlet pressing plate 0 and the circuit breaker operate and energy storage power supply 0, the state code is 0011100, and an image with a time mark and an image identification result are associated; when the switch cabinet is in a hot standby state, the switch cabinet is in the state when the circuit breaker 0, the handcart 1, the grounding switch 0, the valve baffle 0, the secondary aviation plug 1, the tripping outlet pressing plate 1 and the circuit breaker operate and energy storage power supply 1, the state code is 0100111, and an image with a time scale and an image identification result are associated; when the switch cabinet is in a test or cold standby state, the switch cabinet is in the state when the circuit breaker 0, the handcart 0, the grounding switch 0, the valve baffle plate 1, the secondary aviation plug 1, the tripping outlet pressing plate 1 and the circuit breaker operate and energy storage power supply 1, the state code of the switch cabinet is 0001111, and an image with a time mark and an image identification result are associated; when the switch cabinet is in a switch maintenance state, the switch cabinet is in the state when the circuit breaker 0, the handcart 0, the grounding switch 0, the valve baffle plate 1, the secondary aviation plug 0, the tripping outlet pressing plate 0 and the circuit breaker operate and energy storage power supply 0, the state code is 0001000, and an image with a time mark and an image identification result are associated; when the switch cabinet is in the state of being simultaneously overhauled by outgoing lines and switches, the switch cabinet is in the state when the breaker 0, the handcart 0, the grounding switch 1, the valve baffle plate 1, the secondary aviation plug 0, the tripping outlet pressing plate 0 and the breaker operate and energy storage power supply 0, the state code of the switch cabinet is 0001000, and simultaneously, images with time marks and image identification results are correlated. The specific cabinet state representation in the different operating states can be listed in the manner of table 2.

The checking process is checking the state of the switch cabinet in 6 different states, and the state information of the switch cabinet acquired each time must accord with the state information stored in the current library, namely the positions of 7+2 are consistent, wherein 7 refers to the state information of the switch cabinet in 7 types, and 2 refers to two image recognition results.

Before the switch cabinet state operation is carried out each time, the state of the switch cabinet needs to be checked, if the state is consistent, the next operation can be carried out, and if the state is not consistent, the operation is alarmed and locked. In addition, the alignment between the recognition result and the reference recognition result can be expressed by using structured data. When the video acquisition grounding switch on-position image is consistent with the grounding switch on-position reference picture, the structured data value is 1, and meanwhile, the image with the time scale is stored. When the video acquisition grounding switch sub-position image is consistent with the grounding switch sub-position reference picture, the current grounding switch can be judged to be in an effective sub-position, the structured data value is 0, and meanwhile, the image with the time mark is stored; when the video acquisition grounding switch image is inconsistent with the grounding switch branch position and the closing position reference picture, the current grounding switch is judged to be in an invalid position, the structured data value is 2, and the image with the time mark is stored.

Similarly, when the shutter baffle closing image acquired by the video is consistent with the shutter baffle closing reference picture, the structured data value is 1, and the image with the time scale is stored. When the video acquisition valve baffle opening image is consistent with the reference picture of valve baffle opening, the current grounding switch can be judged to be in an effective sub-position, the structured data value is 0, and the image with the time mark is stored; when the image of the shutter baffle of the video acquisition is inconsistent with the reference picture of opening and closing the shutter baffle, the current shutter baffle can be judged to be in an invalid position, the structured data value of the shutter baffle is 2, and the image with the time mark is stored.

Further, step 104, thereafter, further includes:

and under the condition that the verification is passed, carrying out state conversion operation on the switch cabinet to obtain updated switch cabinet state information.

The state operation can be carried out on the switch cabinet after the verification is passed, and for the obtained updated state information of the switch cabinet, if the state information of the switch cabinet needs to be adjusted today, the state verification still needs to be carried out firstly, and the next step of operation can be carried out only after the verification is passed.

According to the method for checking the state of the switch cabinet, various states of the switch cabinet are checked based on a redundancy checking mechanism; specifically, the method can be divided into checking of the coding state and checking of the image recognition result; the coding can edit various switch cabinet states into a state sequence, and the image identification method can accurately identify the specific switch cabinet states to obtain the specific degrees of the switch cabinet in different states. The state of the switch cabinet is judged more accurately and reliably by combining two checking results. Therefore, the technical problem that the reliability of identification of the switch cabinet state is lacked in the prior art, and various switch cabinet states cannot be reflected, so that great potential safety hazards exist in monitoring can be solved.
