1. System introduction:
The wireless ad hoc network based on Ad Hoc technology is a special wireless mobile network in which all nodes in the network have equal status and no central control node is required. The nodes in the network not only have functions required by ordinary mobile terminals, but also have message forwarding capabilities. This kind of mobile network capable of rapid and automatic networking has become a research hotspot in recent years.
The system has completely independent intellectual property rights. Six invention patents have been accepted in key technologies such as routing layer and MAC layer (patent acceptance numbers: 200510028236.7, 200510111932.4, 200510111930.5, 200510111931.x, 200510111935.8, 200610025247.4), reaching the current domestic level Advanced level.
When the system is running, there is no network usage fee, the equipment investment is low, the communication is more reliable than the GPRS system, and it has a high degree of flexibility. It can communicate with the existing Internet and other networks.
2. Technical features and functions
The system is composed of multiple micro-power wireless communication modules and computers or wireless handheld terminals, and realizes the Ad hoc self-organizing network function in the 2.4GHz frequency band. The network has an energy-saving mechanism, and it can maintain 1 to 1.5 years of working time when powered by 2 AAA batteries; the intelligent network real-time detection and management function can understand the working status of each node at any time; it does not require network infrastructure Support, automatic networking, automatic data forwarding; data transmission rate up to 225kbps. The system has a number of independent intellectual property rights.
Demonstration kits can now be provided: 5 standard demonstration/application modules (one of which is used as a control node connected to the computer), which implements the following functions:
1. Demonstrate the automatic dynamic networking function of the self-organizing network micro-power wireless communication system;
2. Demonstrate the automatic routing of data transmission in the network and the function of how data is transmitted in the network;
3. The function of displaying the connection status of the network wireless link and the actual data transmission statistics of each network node;
4. Demonstrate multiple data collection functions of the entire network;
5. Demonstrate the control function of the control center to remote network nodes;
Three, application occasions
The system has been widely used in hospital bed management, road traffic management, water quality monitoring, coal mine safety early warning systems and other occasions.It has been applied in Jiading Central Hospital, and the application in Shanghai Zhonghuan Road Intelligent Road Management System is being implemented
