[Abstract]:The appearance of large and dense buildings and underground buildings in cities leads to longer and more complex building passages. The frequency of personnel emergencies in public places is more and more high. The design of intelligent fire evacuation system with strong ability to adapt to the environment can effectively protect personnel escape. System communication is one of the key parts. In order to meet the environmental adaptation and high efficiency of the evacuation communication system, this paper designs an intelligent evacuation communication system protocol based on C-MBUS, and gives the implementation method. The main contents are as follows: (1) the present situation of evacuation system at home and abroad is studied, and the market demand and national standard are investigated, and the specific requirements and future development direction of the intelligent evacuation communication system designed in this paper are given. On this basis, the types of industrial networks and the main communication protocols in industrial networks are studied, and the shortcomings of the existing intelligent evacuation communication systems are analyzed and improved. (2) according to the function requirements and specific indexes, the overall communication architecture of the intelligent evacuation system is given, and the hardware system based on C-MBUS is designed. Each part of the system is the communication module based on CMT100 and CMT001, respectively. The system power supply module, indicator node controller, relay controller, master controller and so on. The principle and realization circuit of each part are described in detail. (3) on the basis of Modbus protocol, an improved communication protocol is developed to optimize the architecture of intelligent evacuation system. The communication protocol functions mainly include data updating, data reading, error table query, address assignment, etc. Address deletion and error detection, host and slave protocol frame format, data meaning are introduced in detail. It also innovates the concept of intelligent evacuation system virtualization in main control memory at all levels, explains the storage architecture of virtualization in detail, and introduces the concept of data table, including address allocation table, in order to optimize memory utilization. The function of the lower system communication error table and the lower system error table are explained. (4) according to the design of intelligent evacuation hardware system and communication protocol, this paper designs the software of main control at all levels, including memory allocation of storage architecture, serial communication module, data packet parsing module of main control at all levels. Data synchronization communication processing module. This paper describes the program flow of each module in detail, and gives the program flow chart. (5) according to the communication protocol and the hardware and software design, the prototype is developed successfully, and the control of each node and the data collection are completed by the prototype. The final test shows that the intelligent evacuation communication system based on C-MBUS designed by this project can run stably, and realize the function of automatically joining the network, automatically detecting errors, improving the control speed and simplifying the difficulty of node expansion. The target of the expected design has been achieved.
