Because of Urumqi Petrochemical Plant needing a large amount of industrial water, in view of their water supply problem, this paper proposed to use wireless data transmission technology to install a wireless gateway on the far flow transmitter, through the equipment RS485 interface, the cumulative flowing data accessed radio station to get the data by using the MODBUS protocol. Eventually it improves the efficiency of the water supply and centralizes management.

Data Transmission System

Lightning is an environmental phenomena that cause many fatalities and property destructions in Malaysia since the country is located in the high isokeraunic area. To reduce the fatalities an alert system should be developed. The alert system can consist of several Rotating Electric Field Mill sensors which are installed in spread. Data from the sensors must be gathered in a data centre building for observation,  analysis, and triggering an alert signal. Therefore, the objective of this work is to develop a data transmission system by using a wireless method. The wireless data transmission system consists of a microcontroller, voltage divider, and GSM module. Hardware and software development is carried out to achieve the objective. Furthermore, to test the transmission system a function generator is connected to the analog digital converter input of the microcontroller. By varying the magnitude of the function generator output an observation on data transmission is carried out. It is found that the magnitude of receiving data which is displayed on the website is exactly the same with the sent data. In here in lab wireless data transmission system devices and a website to observe the transmitted data from Rotating Electric Field Mill sensors has been successfully developed.

Bus Architecture

According to current technological situation that most of the existing Modbus networks are based on cable and the disadvantages of cable in bus architecture such as troubles during installation, much inconvenience in maintenance debugging and the potential safety hazard following high non-isolated, a design proposal based on Modbus digital transmission module is presented to realize the communication function without cable. During the design proposal, a wireless RF A7108 chip offered by SHENGKE electronic company is selected as the transmission carrier, which is followed by the transmit-receive pattern of Modbus protocol. And the transmission reliability of wireless data is guaranteed by the CRC check of every frame in the process of data transmission. This design can improve the problem of cable dependence in the traditional bus system and has a certain practical value within 500 meters radius in the industry with cable arrangement difficulty.
