the mobile APP server side provides operation ticket execution progress inquiry and operation ticket execution result returning service;
and the anti-error cloud center client performs service interaction with the anti-error host server and the mobile APP server through an extended message mail protocol.
The following is a specific implementation of the present invention.
(1) Technical architecture
In the transformer substation switching operation management service, the anti-misoperation cloud center, the anti-misoperation host and the mobile APP are respectively defined as a client and a server. The anti-error host server provides intelligent ticket forming, operation ticket simulation preview and real-time anti-error check services; the mobile APP server side provides operation ticket execution progress inquiry and operation ticket execution result returning services. The anti-misoperation cloud center serves as a client to carry out service calling and data calling, and online control of the execution process of the switching operation ticket is achieved. The technical architecture is shown in fig. 1.
In order to shield the technical difference of the anti-error host of different manufacturers, an expanded message mail is adopted in the communication mechanism design of the client and the server to realize the transmission of the operation ticket and the request/response of the service. The client service gateway receives a service request of a man-machine system, for example: generating an operation ticket, simulating preview of the operation ticket and the like, serializing the service request into a message mail form, and routing the message mail form to a service gateway of a corresponding transformer substation; the transformer substation service gateway analyzes a service request method, parameters and the like from the message mail and calls a local service; the service response result is returned to the client in the form of a message mail.
(2) Service interaction protocol
And the anti-error cloud center performs service interaction with the transformer substation anti-error host and the mobile APP through the expanded message mail protocol. In order to design and implement uniformity and high efficiency of communication interaction, 5 different command fields of 'request operation ticket', 'simulation rehearsal of request operation ticket', 'error-proof check of request operation ticket', 'execution result of request operation ticket' and 'request pressing plate state' are defined for distinguishing, and cloud and edge service interaction is achieved. The service command fields are as follows:
requesting an operation ticket file: SOA:// optical key (persistence = substation name, device = device name, preState = device original state, state = device target state, update _ mode =1, time = operation ticket update time);
requesting simulated rehearsal of operation tickets: SOA:// simulate (substtation = substation name, ticket _ id = operation ticket number);
request for error proofing of operation tickets: SOA:// verify (substtation = substation name, ticket _ id = operation ticket number, action _ seqno = operation action number, auto _ block = 1);
request execution result of operation ticket: SOA:// result (substtation = substation name, ticket _ id = operation ticket number, action _ seqno = operation action number);
request for platen status: SOA:// signal (substtation = substation name, ticket _ id = operation ticket number, signal _ name = platen signal name).
In order to meet the cloud-edge service cooperation requirement, when a wide area service interaction protocol is designed, the technical difference of an anti-misoperation host, the invalidity of service interaction and the safety of data transmission need to be considered in a key manner. The message mail mechanism is used as a mature data transmission mode and exchange rule, and is applied to the transmission and exchange of message mails in and among dispatching control mechanisms of power grids at all levels, between dispatching control mechanisms and transformer substations and power plants, and between production control areas and management information areas in a power system. However, the message mail only specifies the transmission format of the file-class data, and is not perfect for the data interaction session (session); the method and the system realize the wide area service interaction based on the message mail by expanding a message mail protocol, adding new type description information of 'transmission type = service', defining a service header in a 'content' field and defining a service request body/a service response body in a mail attachment.

(3) Service gateway processing mechanism
As shown in fig. 2, the substation service gateway machine is responsible for receiving the message mail, analyzing service calling information, and initiating calling to services such as intelligent ticket formation and preview simulation of the error prevention host. In order to improve timeliness of service calling, multiplexing of long service connection is achieved through a service client connection pool technology, idle overtime time of service connection is set, and idle of a large number of network connections of error-proof hosts is avoided.
The anti-misoperation cloud center service gateway machine is responsible for receiving a service request sent by a human-computer system, packaging the service request into a message mail and routing the message mail to a corresponding substation service gateway machine; and meanwhile, receiving a message mail sent by the substation service gateway machine, analyzing and returning to the human-computer client. And the request _ id field in the service request header is used as the unique identifier of one-time service request/response session to realize the matching of the message mail.
