Distribution network automation terminal

Abstract

The invention discloses a distribution network automation terminal. Each functional unit is provided with a CPU. Each CPU firstly organizes, analyzes, and stores original data of the unit, and then the data is sent to a core processing unit through a communication bus, and the CPU receives data of the core processing unit and controls execution action, preventing the core processing unit from collecting the original data of each functional unit, and improving reaction speed of the core processing unit. Each CPU is connected with the core processing unit through the communication bus, so that the number of system signal lines is reduced, mutual interference of the signal lines is reduced, and system anti-interference capability is enhanced. Each functional unit communicates with the core processing unit through double networks. When a main communication network has faults, a standby communication network is started immediately, so that anti-fault communication capability of the system is improved. Each functional unit is provided with a ferroelectric storage, so as to independently store data and SOE events, and the data and the SOE events are not lost in power-off. Each CPU automatically identifies the address coding of a bus board, so that whole system wiring is concise. The distribution network automation terminal simplifies design and saves cost.

Description

technical field [0001] The invention relates to the technical field of distribution network automation, in particular to a distribution network automation terminal. Background technique [0002] The existing distribution network automation terminal includes a main controller and multiple functional units, and the same functional unit (such as analog quantity acquisition unit) may be set up at the same time, and each functional unit must be connected to the main controller. The collected information is fed back to the master controller or executes the command of the master controller. However, because there are many functional units in the distribution network automation terminal, the main controller must directly collect information or output commands for each functional unit. The workload of the main controller is very large, which seriously affects the response efficiency of the main controller; and Each functional unit is connected to the main controller through a signal...
