Specifically, the primary metering device is a transmission unit which converts the process parameter physical quantity into a standard analog quantity signal through energy conversion in a production automation system, and the standard signal is transmitted to a display unit or a signal acquisition control unit through a meter line after the conversion so as to display, meter and operate and control the production process parameters. With the increasing production automation degree, centralized control and intelligent control systems such as DSC, PLC, DDC and the like are widely applied to production automatic control equipment systems, so that the original conventional display control instrument is replaced. However, no matter what kind of control system is adopted, the primary metering instrument which plays a role in signal acquisition and conversion is an irreplaceable basic link in the production process, and the installation quality of the primary metering instrument is directly related to the accuracy, sensitivity and stability of process parameter acquisition, so that the detection, metering and control of the whole automatic control system are influenced.

Further, the device acquisition layer 1 further comprises a converter; the converter is used for converting the energy consumption data collected by the primary metering instrument from analog signals to digital signals.
A converter refers to a device that converts one signal into another signal. The signal is in the form or carrier of the information present. In automated instrumentation and control systems, it is common to convert one signal into another compared to a standard or reference quantity in order to couple the two types of instruments, and therefore the converter is often an intermediate link between the two instruments or devices.
Further, the converter is connected with the primary metering instrument through an M-BUS BUS.
The data transmitted on the bus is important data such as water, electricity, gas and the like consumed by an end user, so that the requirement on the bus for resisting external interference is very high, various capacitive and inductive coupling interferences can be resisted, and all the slave devices and the master device are isolated from each other. Meanwhile, the networking cost is required to be relatively low, a shielding cable is not needed for the transmission line, and in order to save the cost, a remote power supply mode is adopted to provide power for the slave equipment so as to reduce the use of components as far as possible. The M-BUS is a BUS structure designed specifically for the data BUS that consumes the measurement instruments and counters to transfer information. M-Bus has many aspects of application in building and industrial energy consumption data collection.
Furthermore, an M-BUS interface converter is used for switching between the primary metering instrument and the M-BUS.

It is a common cold and heat supply end device.
Further, the application management layer 3 is further configured to convert the acquired energy consumption data into a message and output the message.
