Abstract

The invention relates to an electricity utilization collecting method based on a redundant bus and a modular terminal and a system corresponding thereto, and belongs to the field of low-voltage electricity utilization collection. Collecting modules of the device can operate independently to control the collecting devices under the collecting modules to be interacted with the bus with a redundant function or a communication module. The bus with the redundant function is controlled by means of a bus control unit to detect the work states of the modules, and meanwhile, when a master control module works normally, the bus is responsible for data interaction of the master control module; and under the circumstance of the abnormal master control module, electricity utilization information (that is, a direct collecting mode) is uploaded through cooperative work of the collecting modules and the communication module. As the collecting modules are connected one another through the bus, redundant backup is performed among the collecting modules with similar functions; and when one of the collecting modules has a problem, the bus control unit can immediately turn off connection of a power supply and the bus according to the work states, so that bus failure caused by an individual failure module is avoided, and data is immediately and stably collected.

Description

technical field [0001] The invention relates to electricity information collection technology, in particular to a redundant bus-based low-voltage electricity information collection method, a modular terminal and a system. Background technique [0002] The electricity consumption information collection system has been comprehensively constructed since the National Grid promulgated the standard in 2009. So far, the collection coverage rate has reached more than 97%, and the construction goal of "full coverage, full collection, and full cost control" has been basically realized. It has strongly supported the improvement of the level of marketing automation, built a collection network covering the whole country, formed the largest Internet of Things, and provided data support for the further development and optimization of the power grid. The acquisition system is mainly composed of acquisition objects, collectors, and concentrators at the basic layer of the IoT system. The col...
