Modular intelligent fusion terminal and module interface matching method based on analog bus communication

Abstract

The invention provides a modular intelligent fusion terminal and module interface matching method based on analog bus communication. The invention also provides a modular intelligent fusion terminal and a user module based on the method. The user module is inserted into any universal interface of the modular intelligent fusion terminal; and the modular intelligent fusion terminal performs voltagedetection on each universal interface in real time, searches the user module feature configuration table according to the voltage detection value of each universal interface, acquires each user modulefeature, and inputs the universal interface number and the corresponding user module feature into the universal interface IO mapping table to complete matching. When the method is applied, automaticidentification of various bus and various equipment type combinations can be realized, and then the corresponding sub-functions are started so that the functional requirements of users are met; and any user module can be inserted into any slot so that the user module is convenient to expand and operate.

Description

technical field [0001] The invention relates to the fields of power user information collection, distribution transformer monitoring, power load regulation, etc., and realizes the connection between the terminal body and various interfaces and functional modules through an intelligent fusion terminal based on an analog bus self-adaptive module interface software and hardware implementation method. The automatic matching of groups improves the compatibility, scalability and maintainability of the system. Background technique [0002] In the field of power distribution terminal equipment, the modular design of hardware terminals and the design of universal slots have become the basic design methods of equipment hardware, which have the advantages of being customizable and easy to expand; the modular terminals still have the following limitations: [0003] 1. A variety of bus communication protocols can be used, but the user module must be inserted into the corresponding slot i...

Problems solved by technology

[0004] 2. It is not limited by the insertion order and insertion position, but the communication method between the hardware terminal and the module is fixed, that is, only the same interface bus type can be used for communication

[0006] In summary, the design in the prior art does not realize the interface bus independence and module function independence of the modular design, and cannot meet the use requirements
