Embodiment 1

[0076] Please refer to Figure 4 and 5 , Embodiment 1 of the present invention is:

[0077] A method for performing local interconnection and communication with a smart meter 3 by using a smart phone instead of a traditional handheld terminal device, comprising the following steps:

[0078] Step 1:

[0079] The smart phone downloads the application function of the embedded meter and the App driven by the portable reader 2 from the server of the remote monitoring center through GPRS / 3G / 4G / WIFI / USB, and installs it.

[0080] Step2:

[0081] Insert the portable reader 2 into the Micro USB interface of the smart phone, and the portable reader 2 notifies the smart phone that a new device is connected through the smart phone USB protocol such as AOA (Android Open Accessory Mode); OTG function, the portable reader 2 does not need an additional power supply, otherwise the portable reader 2 needs an additional power supply.

[0082] Step 3:

[0083] The smart phone performs a wri...

Abstract

The invention provides a meter reading method and a meter reading system for an electric meter. The method comprises the following steps: building communication connection by an intelligent terminal and a personal reader-writer through a USB interface; driving the personal reader-writer to transmit a meter reading request signal by the intelligent terminal; receiving the meter reading request signal by the intelligent electric meter, and then reading the electric meter according to the meter reading request signal to obtain meter reading data; demodulating the meter reading data to obtain a meter reading data signal, and then transmitting the meter reading data signal; receiving the meter reading data signal by the personal reader-writer, then demodulating to obtain the meter reading data, and transmitting the meter reading data to the intelligent terminal; and displaying and storing the meter reading data through the intelligent terminal, and simultaneously uploading the meter reading data to a remote monitoring center server. According to the meter reading method and the meter reading system for the electric meter provided by the invention, the defects that a handheld meter reading terminal in the meter reading technology is large in size, the stored resource is small, h the cost is low and the meter reading efficiency is low are solved.

Description

technical field [0001] The invention relates to the field of meter reading in electric power systems, in particular to a meter reading method and system for electric meters. Background technique [0002] The meter reading process in the prior art is mainly realized through the information interaction between the traditional handheld meter reading device and the electric meter. The existing hand-held terminals are too bulky and have limited storage resources. Not only are they inconvenient to carry, but they also cost a lot. Furthermore, the speed of reading and storing electricity meter data is also very slow, and the efficiency of meter reading is low. The information interaction process between the follow-up and the remote monitoring center is also relatively complicated. Therefore, it is necessary to provide a meter reading method and system for electric meters to overcome the above problems. Contents of the invention [0003] The technical problem to be solved by the...
