USB (Universal Serial Bus) meter reader and meter reading method thereof

Abstract

The invention discloses a USB (Universal Serial Bus) meter reader and a meter reading method thereof. The USB meter reader comprises a central processing unit, a USB read and write control chip, a 485 communication chip and a USB socket, wherein the central processing unit is electrically connected with the USB read and write control chip and the 485 communication chip respectively, and the USB read and write control chip is electrically connected with the USB socket. The USB meter reader has the advantages of simple structure, convenience for use and safety for data; every one can read the meter by using the USB meter reader without technical training so that the meter can be read by staffs of property management companies; and the meter reading method is extremely suitable for national conditions in China.

Description

technical field [0001] The invention relates to a meter reading device for a meter reading system of a meter (such as a water meter, an electric meter, a gas meter, a heat meter, etc.), in particular to a USB meter reading device and a meter reading method thereof. Background technique [0002] Meters such as water meters, electricity meters, gas meters, and heat meters have been very common in my application, and have entered thousands of households. However, the meter reading work of meters is still in the stage of manual meter reading. The table is time-consuming and laborious, and the accuracy and timeliness cannot be reliably guaranteed, which leads to the inability of relevant marketing and enterprise management software to obtain sufficiently detailed and accurate raw data. Generally, manual meter reading is performed on a monthly basis, which is feasible for user metering, but it is not enough for relevant supply departments to conduct deeper analysis and managem...

[0002] Meters such as water meters, electricity meters, gas meters, and heat meters have been widely used in my application and have entered thousands of households. However, the meter reading work of meters is still in the stage of manual meter reading. The table is time-consuming and laborious, and the accuracy and timeliness cannot be reliably guaranteed, which leads to the inability of relevant marketing and enterprise management software to obtain sufficiently detailed and accurate raw data

Generally, manual meter reading is done on a monthly basis, which is feasible for user metering, but it is not enough for relevant supply departments to conduct deeper analysis and management decisions

With the increase of urban population and high-rise buildings, the workload of manual meter reading is increasing day by day, and the operation and management costs are gradually increasing.

This model shows problems such as low management efficiency, poor social benefits, and prominent safety issues.

Difficulty in household meter reading, disturbing residents, slow data statistics, lagging charges, slow cash flow, unreasonable distribution and other problems that have long plagued residential users and administrative units

With the development of science and technology, many wireless meter reading systems have appeared, but the equipment investment is high, and there are still certain operating costs
