Description
Technical field
Adopted the present invention relates to power information acquisition technique, more particularly to a kind of low-voltage power information based on redundant bus
Diversity method, modular terminal and system.
Background technology
Power information acquisition system started all-round construction from national grid issuing standard in 2009, and coverage rate is gathered so far
Up to more than 97%, the basic construction object for realizing " all standing, full collection, control in full ".Marketing automation is provided powerful support for
The raising of level, has built up the collection network in the covering whole nation, constitutes the Internet of Things of maximum, be the further development of power network with it is excellent
Change and provide data supporting.Acquisition system is mainly made up of in the basal layer of things system acquisition target, collector, concentrator.
Acquisition target etc. the ammeter, equipment for monitoring power quality of all kinds of low-voltage customers, be responsible for being adopted a range of by collector
Concentrator is uploaded in collection meter data set again, concentrator will gather the meter data come up and be uploaded to main station system.These three
Part constitutes a basic acquisition units, and function and the performance of concentrator decide the realization of the function of system.
In current system, concentrator is usually taken a main control unit and extends out communication module composition, and communication module is received
Control in main control unit, it is necessary to there is the processor to carry out parameter configuration in advance, it is impossible to which independent control correlation acquisition unit runs.In master control
In the case that unit breaks down, its communication function will fail because of the blocking that main control unit uploads channel.
With the expansion of power information acquisition range, in the demand in other energy monitor fields such as gas meter, water meter, charging pile
Increasing, existing acquisition terminal not only can not functionally meet requirement, and reality is also unable to reach in operational reliability
Use requirement.Especially, existing terminal is monoblock type framework, and coupling is strong between various pieces, and it is right that part goes wrong
Whole terminal impacts are very big.Specifically, after certain collecting unit breaks down in system, the high level of its output will block whole
Individual system bus, causing the data of other collecting units cannot effectively be transmitted.
Current power information acquisition system is functionally, it is desirable to which the power information acquisition terminal can not only meet meter
The requirement of the acquisition target of the other industry outside device, and need it to face increasingly complex electrical equipment, some devices will
Monitor in real time is sought, it is necessary to bigger data bandwidth.Due to data volume increase, this data it is not absolutely required to main control unit treatment.
By these data be uploaded to the more powerful server of operational capability can yet be regarded as it is a kind of effectively and the mode of simplicity.But this same need
The power information acquisition terminal is wanted to possess reliability higher.To meet the expansion of power information acquisition range, and collection
The reliability of the increase of data bandwidth, existing acquisition terminal, its function and its work is unable to reach requirement.
