The paper considers the list of functions to be implemented in the special software of the artillery control automation control system of the self-propelled artillery division of the airborne forces to ensure the reliability of operation. The principles implemented in the control subsystem for the control of the operation of the artillery control automation control system developed by the Rubin research and production enterprise are described. They make it possible to significantly reduce the load on network and computing resources by eliminating parallel streams of requests for duplicate data from simultaneously performed special software tasks. Solutions are proposed for automating the operation of the communication and data transmission subsystem, providing reliable data transmission, automatic selection of the communication channel having the highest throughput, automatic retransmission route construction, providing the maximum capacity with the minimum number of relay nodes during the movement of control machines and self-propelled artillery pieces. The analysis of the transport level protocols is carried out and the choice of the optimal protocol - SCTP is proved. The analysis of routing protocols is made and the choice of the optimal protocol - AODV is justified.

Automation Control

With the accelerating process of world industrialization, countries pay more attention to industrial modernization. In order to solve the problems of traditional control technology and system with low accuracy, high energy consumption, and high delay in industrial automation control and the difficulty in adapting to the new industrial production process, the new industrial automation control system is discussed and studied. The industrial automation control is studied, and a new monitoring system is designed for automation control by using ZigBee wireless communication technology. The design of the system data communication scheme is completed by the in-depth study and summary of ZigBee wireless communication technology. The hardware structure and software structure of ZigBee wireless communication module are designed, and the wireless monitoring system using ZigBee is established. Taking the production workshop of a pharmaceutical factory as the monitoring object, the working stability and data transmission efficiency of the model are tested. The experiment shows that the ZigBee wireless transmission model has lower temperature and better stability than the wired transmission system in the working process. Compared with the traditional wired control system, the temperature of ZigBee wireless control system is lower when it works. The difference between the highest temperature and the lowest temperature is 0.1°C. In the overall work flow, the system temperature is lower than that of the wired control. ZigBee wireless control has good stability. Subsequently, the method of manually setting obstacles is used to test the effectiveness of data transmission. The experiment found that in the absence of barrier, the maximum effective transmission distance was 40 meters, and the packet loss rate was very low, which could ensure the timeliness of data. Therefore, this system can be applied to industrial automation control. The research results can provide some reference for the design of new control systems in other industrial control fields. The improved system can also be applied to other industries. ZigBee is a short-range technology for wireless sensor networks, and it is a two-way communication technology with low power consumption, low data rate, and low cost. It can be applied to automatic control and remote control. This provides a platform for wireless networking and control of small and cheap devices. ZigBee will not compete with connection technologies such as Wi-Fi. Meanwhile, it will greatly stimulate the progress of the industrial market.

It discusses the reasons of the data transmission time delay and packets loss based on the theory of net data transmission. Aimed to the question of the time delay of data transmission and packets loss, the control system models are set up to analyze their influence to the performance of the control system. Based on the synchronous control model analysis with wireless data transmission, a method to control the system is reached with the state prediction when the communication error or data loss appears. It can control constantly when communication errors appear, and also it can get the most error period by numerical analysis.

Abstract Communication between the process stations of the distributed control system is carried out. By the supervision and therapeutic systems of the stations communication process diagnosis is performed. Supervision and therapeutic systems are responsible for the security of transmitted data. The security is considered in this article mainly in the aspect of resistance to external destructive factors on the data transmission process. It is assumed that the transmission security can be provided by mechanisms protecting the integrity of the transmitted data. Correctness of the data is controlled by using one-way hash function calculated on the basis of the transmitted value variable and also is attached to the transmitted data. This allows to maintain the integrity of the transmitted process data. A solutions using one-way hash function to protection of the transmission before changing message contents (caused by eg. intruder interference) are proposed in the article.
