Description of the invention The invention relates to the field of meter reading device technology.
BACKGROUND OF THE INVENTION In the process of actual meter reading, a meter reader needs to use a dedicated connection line to connect the data input interface of the meter reading device with the data output interface on the water, electricity, and gas meters for meter reading. In order to simplify the operation flow, the connection line is always inserted in the data input interface of the meter reading device, or the connection line is directly led out from the data input port of the meter reading device, thereby eliminating the need for a plugging and unplugging of the connection line. However, even if this is the case, each time a meter reader copies a meter, plugging in and out once is a necessary step. That is, the connection line is connected to the corresponding meter, and the work efficiency is low.
In addition, meters such as electricity meters, gas meters, and water meters are generally located in relatively high places. This can effectively prevent others from intentionally damaging or stealing electricity or stealing gas. However, it causes a lot of troubles when reading meter readings. You need to climb the ladder to read the meter. There is a danger of falling and falling. The climbing operation further reduces the efficiency of meter reading.
Summary of the Invention The technical problem to be solved by the invention is to provide a smart meter reading terminal, which has the advantages of convenient use, storage of data, accurate meter reading, and high efficiency.
For this purpose, the smart meter reading terminal includes a data acquisition unit, a support bar, and a meter reading host. The data acquisition unit and the meter reading host are fixed on both ends of the support bar and perform data communication through the serial port. The data acquisition unit The image information and the electronic tag information of the electric meter are collected, and the meter reading host is used to process the data collected by the data acquisition unit and displays the result on the display screen of the meter reading host.
The structure of the invention
The advantage of adopting this technical scheme lies in that the meter reading terminal includes a data acquisition unit and a meter reading host. The data acquisition unit includes a camera and an induction coil. The camera captures the image data of the table and collects the electronic label information of the table through the induction coil. , And through the meter reading host to display the relevant data of the table on the display, the meter reader operating the host can read the work. By using a smart meter reading terminal, it is not necessary to climb a meter reading, and it is not necessary to perform meter reading by plugging in a data line, which has the advantages of convenient use and storage of data, accurate meter reading, and high efficiency.
In addition, the meter reading host uses ARM as a processor to process a large amount of information and processing speed; the data acquisition unit is connected to the support rod through a universal joint hose and can be bent at any angle to facilitate meter reading; the meter reading host passes a rotation The mechanism is connected with the support bar so that the host can change the angle and provide the meter reader with different perspectives, which further facilitates meter reading.
