Abstract
The utility model discloses an intelligent wireless meter reading system, and belongs to the field of electric engineering. The intelligent wireless meter reading system comprises an electric energy data acquisition terminal, a singlechip electric energy collection terminal, a general packet radio service (GPRS) module and a remote management upper computer, wherein the electric energy data acquisition terminal meters the electric quantity of an electric meter; the electric energy data acquisition terminal communicates with the singlechip electric energy collection terminal by a recommended standard 485 (RS 485) serial port and sends the electric quantity to the singlechip electric energy collection terminal; the singlechip electric energy collection terminal is connected with the GPRS module; and the GPRS module and the remote management upper computer realize signal transmission by a wireless network. By the intelligent wireless meter reading system, meter reading personnel do not need to read a meter manually from house to house, so that the problems of large errors, large counting workload, probability of artificial mistakes and the like which are caused by artificial meter reading are solved.
Description
Technical field
The utility model belongs to the electrical engineering field, and more particularly, it relates to a kind of Practical Intelligent wireless kilowatt meter reading-out system.
Background technology
At present the domestic meter reading method of China roughly has following three kinds: the one, the conventional artificial meter reading method adopts the meter reading personnel to check meter by hand from house to house, return after the electrical management office copy the manual one by one input manager computing machine of ammeter data in method.This meter reading method error is big, the statistical work amount is big, and the people is that the probability that makes the mistake is big, brings great inconvenience for user and electric administrative department; The 2nd, the pre-payment meter reading method, the meter reading personnel need not arrive the family and table look-up.The user passes through to electric administrative department and buys memory cards such as magnetic card, IC-card, the mode of the consumption of the certain amount of money of advance payment then.When treating the advance payment insufficient in amount, the meter device sends the warning that Sorry, your ticket has not enough value, notifies the user to pay the fees as early as possible.Though this has reduced human factor, need arrive bank or administrative authority when buying consumption, waste time and energy, and the water, electricity, gas table pays dues respectively, many inconveniences are also arranged; The 3rd, obtain the mode of long-distance user's measurement instrument data automatically through dedicated telephone line road (like pay station line, power carrier line, regional wireless station etc.).
Along with the acceleration propelling of China's modernization and the develop rapidly of high-tech technology, make people's life style and working method that huge change take place.One of expulsive force of these changes is exactly the widespread use of a large amount of electronic product, and pretending is the requirement-electric energy of the normal operation of electronic product, and oneself is through becoming the most important resource of entire society's development.
Present meter reading method mainly still adopts the manual metering mode, and this meter reading method reads inadequately accurately, error is big, is difficult for statistics, safeguards.Though China's automatic data logging has been obtained certain development, also do not realize intelligent.Long-distance wireless meter-reading system will become the development trend of automatic data logging.
Summary of the invention
The problem that solves
For the error that overcomes manual metering is big, the statistical work amount is big, the people is that the probability that makes the mistake is big, brings shortcoming such as great inconvenience and the pre-payment inconvenience of checking meter for user and electric administrative department.The utility model provides a kind of novel ammeter, utilizes the GPRS technology to realize intelligent meter reading, realizes remote wireless meter recording.
