Problems solved by technology

[0003] Since the current smart meter uses a single chip to realize the function of the meter, it does not involve the communication transmission between the management unit and the metering unit. Therefore, the current communication method of the smart meter cannot be applied to the dual-core smart meter. Communication requirements of core smart meters

Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0034] The dual-core interaction method for a dual-core smart meter provided in this application can be applied to, for example, figure 1 in the application environment shown. figure 1 It can be a schematic structural diagram of a two-core smart meter. The meter consists of a management unit 101, a metering unit 103, and an interaction module 102 for realizing data interaction between the management unit 101 and the metering unit 103. The interaction module 102 can be the management unit 101. Alternatively, some modules of the metering unit 103 may be implemented, or ...

Abstract

The present application relates to a dual-core smart meter and dual-core interaction method, device, dual-core smart meter and storage medium. The method includes: obtaining current request frame data, and determining a request unit; the request unit includes: a management unit or a metering unit; when the request unit is a management unit, obtain the first frame sequence number of the current request frame data, and modify the address field to the first frame number. A frame serial number is stored in the corresponding buffer area for buffering, and sent to the metering unit through the buffer area; the response frame data is obtained from the metering unit, and the second frame serial number of the response frame data is determined; if the second frame serial number is the same as the first frame serial number, then As the current response frame data; when the request unit is a metering unit, obtain the request frame type corresponding to the current request frame data; obtain the current response frame data based on the request frame type; return the current response frame data to the request unit. By adopting the method, the communication transmission between the management unit and the metering unit can be realized, so as to meet the communication requirements of the dual-core smart meter.

Description

technical field [0001] The present application relates to the technical field of electric energy measurement, and in particular, to a dual-core smart meter and dual-core interaction method, device, dual-core smart meter, and storage medium. Background technique [0002] With the development of energy metering technology, the previous generation of single-core smart meters has been unable to meet the increasingly complex and changeable metering and marketing needs. A new generation of dual-core smart meters came into being. The new generation of dual-core smart meters uses two chips, namely the management MCU chip and the metering MCU chip, which are respectively used to realize the management unit and the metering unit. The management unit and the metering unit operate independently. It is isolated from each other, and the data exchange between the two cores is carried out through the serial peripheral interface communication, so as to realize the physical isolation of the m...
