In most cases

gas density monitoring is based on the the application of soft technology

and the gas density is obtained based on the model operation after detection of the pressure and temperature of the enclosed gas. The pressure and temperature sensor with bus can be directly connected to the industrial edge automatic monitoring system to complete the measurement of temperature and pressure. However

due to the constraints of the drive

the bus-type pressure and type selection of the sensors is fixed and unique in the design and development of the gas density

monitoring system as well as the subsequent maintenance and replacement procedure

which will leads to the robustness and replaceability of the system decrease and be difficult to adapt to the actual situation of a wide variety of integrated pressure and temperature sensors with different buses. In order to overcome this technical bottleneck

in this paper the driving process of several types of typical buses under the Linux platform is studied and analyzed

the unified drive model of the multi-bus under Linux is set up on the basis of summarizing commonalities and generalizing differences

and the technical implementation idea

method and realization process are given. The method is not only applicable to the automatic monitoring system of SF

gas density

but also applicable to similar situations in the industrial field. This technology can greatly improve the flexibility of the structure of the industrial auto-mation detection system and the compatibility with the bus-type instrumentation and sensor categories.
