Embodiment Construction

[0009] Below in conjunction with accompanying drawing, present embodiment is described further:

[0010] Depend on figure 1 It can be seen that the collection and control module completes the collection of the electric energy signal of the electric energy meter and the control of the electric meter; the electronic electric energy meter completes the measurement of electric energy, because the collection and control module uploads the signal collected by the system to the remote management computer via the CAN bus through the communication module , so that the signal can be managed and controlled by a remote computer.

[0011] The electronic energy meter adopts the AD7755 electric energy acquisition chip, and the output pulse signal is used in conjunction with the acquisition control module.

[0012] The collection control module collects and processes the output signals of each user's energy meter, and sends the user's power consumption signal to the communication module. At...

Abstract

The invention provides a special centralized meter reading system for an electric energy meter, which has the main technical characteristics that an AD7755 electric energy acquisition chip is adopted to an electronic-type electric energy meter, and an output pulse signal is matched with an acquisition control module. The acquisition control module is used for processing the output signal of each user electric meter and sending the electricity consumption signal of a user to a communication module. The acquisition control module can be used for controlling the user to switch on and off, an appointed user is controlled to switch on and off when the prestored amount of the user is insufficient or the order of a supervisory computer is received. The centralized meter reading system has the advantages that the automatic meter reading system has good stability and reliability, communication distance is greatly improved, and various problems of reading meters in the prior art can be totally overcome by the site test, the function of automatically reading meters can be realized, and requirements of electric energy meter users, property management departments and power supply departments can be satisfied.

Description

technical field [0001] The invention relates to an electric meter, in particular to a centralized meter reading system specially used for electric energy meters. Background technique [0002] At present, most of the meter reading in our country adopts manual meter reading. This method of meter reading not only brings inconvenience to the work, but also has problems such as heavy workload, low efficiency, inaccurate and untimely meter reading. Contents of the invention [0003] The object of the present invention is to provide a centralized meter reading system for electric energy meters aiming at the deficiencies in the above-mentioned technologies. It can reduce the workload of meter reading personnel, with high efficiency and timely and accurate meter reading. [0004] The object of the present invention is achieved in this way: it is composed of a management computer, a communication module, an acquisition control module, an electronic electric energy meter and the lik...
