Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
The embodiment of the invention discloses a routing inspection rechecking method based on an intelligent sensor for power equipment. As shown in fig. 1, the method for smart sensor based patrol inspection and review of electric power equipment includes the following steps:
step S1: at the fixed point of the inspection, a smart sensor containing an IC card is installed.
The fixed point of inspection is typically where the electrical equipment is located, e.g., converter transformers, high voltage circuit breakers, disconnectors, etc.
Preferably, the smart sensor is a contact or contactless CPU card.
Step S2: and scanning the intelligent sensor by adopting the first terminal, and writing the identification, account number and time information of the first terminal into the intelligent sensor as a record after encryption.
The first terminal is the terminal of the prior patrol. The first terminal is a mobile terminal, and may be, for example, a special scanner, or a mobile phone, a tablet computer, or the like, in which a scanning program is installed. The identification and the account number can determine which inspection personnel perform inspection specifically, and the time information can determine the inspection time of the inspection personnel. This information is encrypted to allow a particular person to review the record.
During the concrete use, when patrolling and examining the power equipment at this smart sensor place, adopt first terminal scanning smart sensor, write in the smart sensor after encrypting the sign, account number, the time information at first terminal for smart sensor has saved the time that the personnel of patrolling and examining patrolled and has patrolled and examined and patrolled and examined by which personnel of patrolling and examining.
Step S3: and after a certain time interval, scanning the intelligent sensor by adopting the second terminal, acquiring the record stored by the intelligent sensor, and encrypting the identifier, the account number and the time information of the second terminal to be used as a record to be written into the intelligent sensor.
The second terminal is the terminal that patrols and examines behind. Similarly, the second terminal is a mobile terminal, and may be, for example, a special scanner, or a mobile phone, a tablet computer, or the like, in which a scanning program is installed. This information is encrypted to allow a particular person to review the record. The identification and the account number can determine which polling personnel perform the inspection, and the time information can determine the time of the polling personnel inspection. This information is encrypted to allow a particular person to review the record.
Generally, the inspection is repeated, that is, the power equipment is inspected again at intervals, and a problem is sometimes found. Therefore, when one patrol personnel holds the first terminal for a certain time after the inspection, the other patrol personnel can hold the second terminal for inspection. The second terminal can read the record stored by the intelligent sensor, so that the inspection condition of the inspection personnel before can be checked.
Step S4: and the second terminal uploads the stored record to the network for rechecking or self-rechecking.
The second terminal can have rechecking capability or not, and the record is sent to the background network for rechecking, so that the previous inspection record can be checked, whether the specific inspection personnel check on time and check are available before is determined, the responsible inspection personnel can be found when the problem occurs, and whether the problem of card punching instead occurs is determined.
Through the steps, networking equipment does not need to be added, rechecking under the offline condition can be realized by adopting rechecking equipment, the cost is reduced, the loophole of the polling or the error of the polling personnel can be found in time, the polling personnel is confirmed not to check by finding the missing card punching record in the rechecking record, the polling personnel is confirmed not to punch the card on time by finding the delay of the card punching time in the rechecking record, and the illegal card punching is confirmed by finding the identifier of the terminal which punches the card out of the polling scheduling plan in the rechecking record, so that the polling condition is convenient to manage.
Preferably, the smart sensor is equipped with a fingerprint module and has a plurality of fingerprints prestored therein. These fingerprints are patrolling personnel's fingerprint generally for the personnel that the check is operating are patrolling personnel whether to patrol personnel's security that the intelligent sensor is unlocked through the fingerprint to patrol personnel, improvement information.
Specifically, the writing or reading operation is performed at the first terminal or the second terminal within a predetermined time after the fingerprint of the user is verified to pass.
Namely, after the fingerprint verification is passed, other operations can be carried out within preset time; if the time is overtime, the fingerprint authentication needs to be carried out again, and other operations are carried out after the fingerprint authentication is passed.
After the fingerprint verification is passed, the inspection personnel which is qualified is indicated to be in operation, so that the first terminal or the second terminal can execute writing or reading operation, and the safety of the whole operation is improved.
Preferably, the number of the first terminals includes at least two terminals, which are the first terminal and the second terminal. As shown in fig. 3, the first and second terminals may be two first terminals having different detection areas. Wherein, the intelligent sensor of a first terminal scanning point of patrolling. In the process of routing inspection, when the routing inspection personnel sometimes cannot complete the remaining routing inspection work, the remaining routing inspection work needs to be delivered to other routing inspection personnel for completion, so that in this scenario, as shown in fig. 2, the routing inspection rechecking method of the embodiment of the present invention further includes the following steps:
step S1: and the first terminal receives the residual data of the fixed point which is not patrolled and transmitted by the first and second terminals through near field communication.
And one authorization code is stored in the data of the remaining fixed points which are not inspected. The authorization codes are generated by interaction between the first and second chips in the first and second terminals and the server and are stored in the first and second chips, the number of the authorization codes is multiple and different, and the server encrypts the authorization codes by adopting a public key. And the first terminal can replace the first and second terminals to carry out the rest routing inspection work through authorization of the authorization code.
Specifically, in order to avoid the failure or the pseudo code of the authorization code adopted by the software, the first and second chips of the first and second terminals are in network connection with the server, the server generates the authorization code according to the polling condition, if the condition of asking for leave or work handover for 3 times per month is allowed, 3 authorization codes are stored in the first and second chips, and the first and second terminals are used one at a time. After the inspection tool is used for 3 times, repeated use can occur to cause the behavior failure of the inspection tool.
In addition, because the electric power field is patrolled and examined, relate to large-scale power transmission equipment in well, generally in remote areas, the network signal is not good, when appearing a patrolling and examining personnel in the course of the work, or ask for on the vacation on the same day, can't carry out work, needs other people to replace to patrol and examine, and under the not good condition of network signal, in order to hand over the work of patrolling and examining fast, it is most effective to adopt the transmission of closely.
Step S2: and after the verification is effective, the first terminal scans the intelligent sensors of the rest non-inspection fixed points, encrypts the identifications, the accounts, the time information and the authorization codes of the first terminal and the second terminal together and writes the encrypted identifications, the accounts, the time information and the authorization codes as a record into the intelligent sensors of the rest non-inspection fixed points.
Preferably, the authorisation code is valid for a predetermined time. The predetermined time is a user-set expiration date. That is, after the preset time is exceeded, the authorization code is invalid, the first terminal is not effectively authorized by the first and second terminals, and therefore the first and second terminals cannot be replaced to carry out the remaining routing inspection work, and therefore safety is improved. For example, if the predetermined time is one month, the authorization code is valid for the one month, and if the first terminal is authorized using the authorization code in the next month, the authorization fails.
Through the steps, the second terminal can clearly see the handover of the polling work and the specific information of both parties of the handover when carrying out the reinspection.
Step S3: and after a certain time interval, scanning the remaining intelligent sensors which are not patrolled and examined with the fixed points by using the second terminal, writing and reading the records, and rechecking the records or uploading the read records to the server for rechecking.
In addition, during the rechecking, the server or the second terminal may also detect whether the pseudo code exists according to the use of each authorization code, so as to find an unauthorized generation card punch.
Through the steps, besides the beneficial effects, the authorization code mode is adopted, so that the problem that the network can not be connected to adjust for routing inspection work under the condition that the network is not good or the power equipment has electromagnetic interference can be effectively solved. In addition, one authorization code can realize the work of rechecking the server and adjusting the rest of the two terminals which are not patrolled.
Preferably, the first and second chips use public key to encrypt the data of the remaining non-polling fixed points, and the method in the embodiment of the present invention further includes:
(1) used authorization codes are sequentially added within three times.
And adding used authorization codes within three times into the data which are transmitted by the first and second terminals and do not patrol the fixed point. It should be understood that the number of times is set to three times in the embodiment of the present invention, but the present invention is not limited thereto, and the number of times may be set according to the number of authorization codes allowed to be used. For example, the polling staff can leave for 3 times in a month unit, and when the polling work needs to be authorized for handover in the month, the authorization codes used within the last three times are added according to the time sequence, so that the following steps can determine whether the authorization codes are valid to determine whether the leave-leaving-requesting times of the polling staff at the first and second terminals in the month are used up.
(2) And the first chip of the first terminal respectively decrypts all the authorization codes transmitted at this time by adopting a private key, if the authorization codes are confirmed to be valid and not repeated, the authorization codes are considered to be valid, and if the authorization codes are not confirmed to be valid, an invalid prompt is output.
Specifically, the used authorization code and the unused authorization code may be respectively identified by using identifiers, so that the first terminal determines which one of the unused authorization codes is. When all the authorization codes are different, the unused authorization codes transmitted at this time are effective, the first terminal is effectively authorized by the first and second terminals, and the first and second terminals can be replaced for polling, so that the safety is improved.
In summary, the routing inspection rechecking method based on the intelligent sensor for the power equipment does not need to increase networking equipment, rechecking under the off-line condition can be realized by adopting rechecking equipment, the cost is reduced, the loopholes of routing inspection or errors of routing inspection personnel can be found in time, and the safety is high; also can hand over the work of patrolling and examining under the special circumstances, the flexibility is high, conveniently manages the condition of patrolling and examining.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
