Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
In an embodiment, as shown in fig. 1, fig. 1 shows a fault diagnosis method for an electric energy meter provided in this embodiment, where an execution subject of the method is a first electric energy meter, and a specific implementation flow of the method includes:
s101: and randomly establishing communication connection with any electric energy meter in the target area, and taking the electric energy meter with the established communication connection as a second electric energy meter.
In this embodiment, the electric energy meters in the target area perform fault mutual detection according to a polling period, and the polling period may be set to 5 hours, 10 hours, or 1 day.
Specifically, in the current polling period, the first electric energy meter can establish a communication request with any electric energy meter in the target area. Specifically, if the first electric energy meter acquires the communication request of any other electric energy meter, it is determined whether the communication connection number of the first electric energy meter exceeds the preset connection number, and if the communication connection number does not exceed the preset connection number, response information is returned to the electric energy meter to be responded so as to establish communication connection with the electric energy meter to be responded.
Similarly, if the first electric energy meter sends a communication request to any electric energy meter, the electric energy meter can search the communication connection quantity of the electric energy meter, and if the communication connection quantity does not exceed the preset connection quantity, the communication request with the first electric energy meter is established.
Illustratively, the preset number of connections may be 3.
S102: if the verification request information of the second electric energy meter is acquired, establishing communication connection with the target electric energy meter according to a communication address of the target electric energy meter carried in the verification request information; the verification request information comprises a fault diagnosis result generated by performing fault diagnosis on the target electric energy meter by at least one electric energy meter which establishes communication connection with the target electric energy meter in the current inspection cycle.
In this embodiment, each electric energy meter is provided with a fault diagnosis module therein, which is used for performing fault diagnosis on other electric energy meters in the target area.
The verification request information comprises a communication address of the target electric energy meter and a fault diagnosis result generated by performing fault diagnosis on the target electric energy meter by at least one electric energy meter which has established communication connection with the target electric energy meter in the current inspection cycle. And each electric energy meter which is in communication connection with the target electric energy meter carries out one-time fault diagnosis on the target electric energy meter and generates a corresponding fault diagnosis result. And if the verification request information only comprises a fault diagnosis result, the second electric energy meter is the electric energy meter which is connected with the target electric energy meter at the first time in the current inspection period, and otherwise, other electric energy meters perform fault diagnosis on the target electric energy meter before the second electric energy meter and generate the fault diagnosis result.
S103: and carrying out fault diagnosis on the target electric energy meter to obtain a fault diagnosis result of the first electric energy meter on the target electric energy meter.
In this embodiment, after the first electric energy meter establishes the communication connection with the target electric energy meter, the operation data of the target electric energy meter is obtained, and the fault diagnosis is performed on the target electric energy meter according to the operation data of the target electric energy meter. Specifically, the fault diagnosis result includes the electric energy meter identification, the current polling period, and each fault type when no fault exists normally/there is a fault. The types of faults include: false operation or refusal operation of a load switch, an ESAM error, a memory card initialization error, low clock battery voltage, an internal program error, failure or damage of a storage device, clock failure, and low voltage of a power failure meter reading battery.
As shown in fig. 2, if the first electric energy meter 1 acquires the verification request information of the second electric energy meter 2, it indicates that at least one electric energy meter has already performed fault diagnosis for the target electric energy meter a before the first electric energy meter 1, and there are no two identical fault diagnosis results in at least one fault diagnosis result before that, therefore, in order to improve the fault diagnosis accuracy for the target electric energy meter, the first electric energy meter 1 also performs fault diagnosis for the target electric energy meter a to verify whether the fault diagnosis result before that is correct, and if the fault diagnosis result of the first electric energy meter 1 is the same as one of the fault diagnosis results in the verification request information, it is determined that the fault diagnosis result of the first electric energy meter 1 is the fault diagnosis result of the target electric energy meter a.
S104: and comparing all fault diagnosis results corresponding to the target electric energy meter, and if the same fault diagnosis result exists in all fault diagnosis results corresponding to the target electric energy meter, sending the same fault diagnosis result to a server as a final fault diagnosis result of the target electric energy meter.
In this embodiment, when the server obtains the final fault diagnosis result of the target electric energy meter, the server stores the final fault diagnosis result, and if the final fault diagnosis result indicates that the target electric energy meter has a fault, a maintenance dispatch list is generated according to the fault diagnosis result, so that the maintenance of the fault electric energy meter is completed in time.
Furthermore, besides the above fault types, the electric energy meter may also have a communication module fault, and if the communication module has a fault, the electric energy meter cannot establish communication connection with any electric energy meter. Therefore, the server can count the fault diagnosis result obtained in the current polling period, compare the fault diagnosis result with the electric energy meters in the locally stored target areas, send a communication connection request to the electric energy meter if the server does not receive the fault diagnosis result of one electric energy meter in the current polling period, and judge the communication fault of the electric energy meter if the server does not respond, and inform maintenance personnel to maintain the electric energy meter as soon as possible.
In one embodiment, the method provided in this embodiment further includes:
if the fault diagnosis results of the target electric energy meter are not consistent, establishing communication connection with a third electric energy meter, and adding the fault diagnosis result of the first electric energy meter to the target electric energy meter into the verification request information, wherein the third electric energy meter is any electric energy meter in the target area except for the electric energy meter in communication with the target electric energy meter;
sending the updated verification request information to the third electric energy meter so that the third electric energy meter performs fault diagnosis on the target electric energy meter to obtain a fault diagnosis result of the third electric energy meter on the target electric energy meter, and determining a final fault diagnosis result of the target electric energy meter according to the fault diagnosis result corresponding to the target electric energy meter.
In this embodiment, it is determined whether the third electric energy meter needs to continue to send the verification request information to the next random electric energy meter in the target area according to the fault diagnosis result of the third electric energy meter, so as to determine the final fault diagnosis result.
In one embodiment, the method provided in this embodiment further includes:
and if the verification request information of the second electric energy meter is not acquired, performing mutual fault diagnosis with the second electric energy meter.
In this embodiment, if the first electric energy meter is not connected to the second electric energy meter and does not acquire the verification request information sent by the second electric energy meter, it indicates that the second electric energy meter has not performed fault diagnosis in the current polling period, so that the first electric energy meter and the second electric energy meter can perform mutual fault diagnosis, and at this time, the first electric energy meter and the second electric energy meter are mutually used as target electric energy meters of each other, and the fault diagnosis of the target electric energy meter is performed through the above process.
In one embodiment, the method provided in this embodiment further includes:
sending the electric energy meter identification generating the error fault diagnosis result to a server so that the server counts the times of generating the error fault diagnosis result by each electric energy meter and updates the weight of each electric energy meter according to the times of generating the error fault diagnosis result by each electric energy meter; the error fault diagnosis result is a fault diagnosis result which is different from the final fault diagnosis result in the fault diagnosis result corresponding to the target electric energy meter;
and acquiring the current weight of each electric energy meter sent by the server, and selecting the electric energy meter which is in communication connection with the first electric energy meter according to the weight of each electric energy meter in the next routing inspection period.
In this embodiment, the server updates the weight of each electric energy meter according to the number of times that the electric energy meter generates the error fault diagnosis result, and the more the number of times that the error fault diagnosis result is generated, the smaller the weight of the electric energy meter is. And the server sends the updated weight to each electric energy meter of the target area every preset time/every time when the weight is updated. Each electric energy meter can preferably select the electric energy meter with larger weight for communication connection according to the weight, and if the electric energy meter does not respond, the electric energy meters are inquired downwards according to the weight sequence until the communication connection is established.
And further, after the fault diagnosis of the target electric energy meter is completed, each electric energy meter in communication connection with the target electric energy meter is disconnected from the communication connection related to the target electric energy meter. So that the other electric energy meters which do not finish fault diagnosis of the current routing inspection period can realize mutual fault diagnosis. And after each electric energy meter in communication connection with the target electric energy meter is disconnected, deleting all data related to fault diagnosis of the target electric energy meter so as to ensure the calculation efficiency of the electric energy meter.
In one embodiment, the method provided in this embodiment further includes:
and if the number of the acquired fault diagnosis results corresponding to the target electric energy meter is larger than N and different, sending all the fault diagnosis results corresponding to the target electric energy meter to a server so that the server carries out fault diagnosis on the target electric energy meter.
In this embodiment, N may be 4.
It can be known from the above embodiments that, in this embodiment, mutual fault diagnosis can be performed between electric energy meters, so as to improve the efficiency of fault diagnosis, in addition, a plurality of electric energy meters in a target area can perform random communication connection to verify the accuracy of a result, a fault diagnosis communication link of a target electric energy meter temporarily established in a current inspection cycle is formed, and fault diagnosis and verification can be realized in an electric energy meter which newly enters the fault diagnosis communication link, so as to improve the accuracy of a fault diagnosis result.
