the calculation analysis engine module mainly comprises two aspects of contents: on one hand, extracting a test calculation formula, arranging the calculation formula according to the national standard of the electrical equipment handover test, and arranging the calculation formula character strings of equipment test sub-items under different conditions according to factors such as voltage level, equipment parameters and the like, wherein the calculation formula character strings comprise a numerical calculation formula and logic selection conditions; and on the other hand, the calculation formula is analyzed and calculated after the request of the client is received.
2. An electrical equipment handover test intelligent control method based on the electrical equipment handover test intelligent control system according to claim 1, characterized in that: the method comprises the following steps:
s1: the client receives an instruction of a user;
s2: a business application interface module of a management and control service background receives a request sent by a client;
s3: the service application interface module executes the request of the client by calling the calculation analysis engine module or the report generator module or directly using the database application component module, returns the processing result to the client and stores the processing result into the database module;
s4, the data sharing device module of the control service background pushes the processing result to a middle database of the cloud data center station in a database mirroring mode;
in step S2, the request received by the service application interface module of the management and control service background is sent by any one of the following modules: the system comprises a test personnel management module, a power grid architecture management module, an equipment ledger management module, a test template management module, a test record management module, a test instrument management module and a log management module which are applied to a web browser, and a personnel photo input module, a test data filling module and an electronic signature module of a mobile application terminal;
in the step S2, a request received by a business application interface module of a management and control service background is sent by a two-dimensional code scanning module of the mobile application terminal;
in step S2, the request received by the service application interface module of the management and control service background is obtained through the bluetooth module of the mobile application terminal.
