Abstract

The invention discloses an NRF2401-based wireless meter reading device and relates to the technical field of wireless data transmission. The device comprises a data acquisition module and a handheld terminal, wherein the data acquisition module is arranged in an electric meter box, is connected with each electric meter, reads the numerical value of the electric meter and transmits the numerical value to the handheld terminal; and the handheld terminal consists of keys, a display module, a storage module, a microprocessor and a printer interface, displays the numerical value on a screen and stores the numerical value in a secure digital (SD) card simultaneously after receiving the numerical value of the electric meters through a wireless module. The device has the characteristics of high data transmission rate, simple mounting, convenience in maintenance and the like. The meter reading time is greatly reduced, and the meter reading efficiency is improved.

Description

technical field [0001] The invention relates to the field of wireless data transmission, in particular to a device for obtaining electric meter values ​​by wireless short-distance data transmission. Background technique [0002] With the vigorous development of public utilities (water, electricity, and gas) in China, ordinary people have put forward higher requirements for the living environment; encouraged by government policies, home automation has developed rapidly. As a link in the intelligent industrial chain - intelligent meter reading system has also been vigorously developed. The traditional manual meter reading method is time-consuming and laborious, the accuracy and timeliness cannot be guaranteed, and there will be some unpleasant embarrassing situations between the meter reader and the user, which is no longer suitable for the development needs of the society. The patent No. 201110117895.3 proposes a wireless meter reading based on WI-FI. However, when the curre...
