Embodiment 1

[0034] see figure 1 and figure 2 , a wireless program upgrade method for electric meters based on RF communication, which is based on figure 1 The system shown operates, which includes:

[0035] The host computer continuously sends update program commands to the ammeter within the first time period, and the ammeter feeds back a handshake signal to the host computer after receiving the update program command;

[0036] The host computer receives the handshake signal and sends an update code to the meter, and the meter receives and stores the update code;

[0037] When an application program exists in the update code, the electric meter runs the application program.

[0038] The meter includes a main control chip, a current and voltage sampling module, a liquid crystal display module, a data storage module, a communication module, a power supply module and a pulse output module. The communication module includes an infrared communication module and an RF communication module...

Embodiment 2

[0045] see image 3 , a wirelessly upgraded electric meter, including a main control chip and an RF communication module connected to the main control chip; Feedback the handshake signal; the main control chip receives the update code issued by the host computer through the RF communication module, and stores it in the memory; when there is an application program in the update code, the main control chip runs the application program.

[0046] The aforementioned electric meter also includes a current and voltage sampling module, a liquid crystal display module, a data storage module, a power supply module and a pulse output module. The host computer sends update codes to the main control chip in sections.

[0047] Use the 3-way 24-bit high-precision AD converter integrated in the main control chip (SOC chip) to sample the live wire current, neutral wire current, and voltage respectively, quantify and convert them into digital signals, and then complete the electrical parameter...

Abstract

The invention relates to an RF communication-based ammeter wireless program upgrading method. The method comprises the following steps of: continuously sending an updating program command to an ammeter in a first time period by an upper computer, and feeding a handshake signal back to the upper computer by the ammeter after receiving the updating program command; receiving the handshake signal by the upper computer and sending an updating code to the ammeter, and receiving and storing the updating code by the ammeter; and when an application program exists in the updating code, operating the application program by the ammeter. The method is capable of reducing the manufacturing cost, improving the working efficiency and accelerating the time of pushing new goods to the market.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of electric power, in particular to a wireless program upgrading method of an electric meter based on RF communication and a wirelessly upgraded electric meter. [0003] 【Background technique】 [0004] The earliest electric energy meter (also known as electric meter) was made according to the principle of electrolysis in 1881. Although this electric energy meter weighed tens of kilograms each, was very cumbersome, and had no guarantee of accuracy, it was still regarded as a pioneer in the scientific and technological circles at that time. An important invention was valued and praised by people, and it was quickly adopted in engineering. With the development of science and technology, in 1888, the discovery and application of alternating current put forward new requirements for the development of electric energy meters. Through the efforts of scientists, the inductive energy meter was born. Since the inductive...
