Design And Development Of The Back-management Software Of The Remote Meter System Via PLC

As the development of the society, people are now expecting higher and higher levels of life, they hope it will be more effective and continently. Now technology is getting more and stronger, so what people are hoping will turn to be realities. A good example is expanding in our life beside.Technique of transmitting data via power line, a new technique developed in the recent years, is used to automatize the fee collecting system in this service and the management of uptown service. In this paper we introduce the components, principles and functions of a Collect meter reading system clearly, which is based on a technology named Power line carrier (which we often call it PLC).Because the technology is via the power line, so we needn't put the line in addition, then reducing the time and money of the work is now possible.In this paper, we discussed the principle of the hardware, the collector and samplers are dissertated basically, which communicate by power line modem. The design schema and the main flow charts of the software are outlined detail. Also we mainly introduce the management software which can control and read the data stored in the concentrators via the telephone line, here we use Oracle as our background database.When we introduce the development of the software, we explain the method of the designing; here we get ideas from the general steps of software engineering. First we should analyze the user's needs, then should we start our work: designing the configure of database, planning the interface of the users, how to communicate via the serials, the management of the system's users, and so on.Because the technology of spread spectrum carrier(SSC) communication is the kernel of the power carrier technology of communication, so we then explicate the chips we use here. And we proposes the structure and functions of the management of Power Line Carrier Collect meter reading system. This is easy to install, and easy to control, and it's really functional.Because this system has used the technology of remote transition,computing and network, and put them together, reading the users' data real-timely. Not only reducing the consuming of people's physicals, but also we can control the status of users, it is a advantage to find problems and deal with them in immediately.This system has been installed and been tested, and be operated in several places. And the result is it has a good performance and is easy to operate. So we have reasons to believe that the Army's market will be huge during the building of the electronic-net of the country and the village and the policy of "one family one electrometer" is executing.
