4. realize the dynamic data exchange at all Mesh terminals in the net;
5. be equipped with 4 tunnel external network interfaces, realize the purpose that fire fighting and rescue on-site wireless emergency communication net and exterior I nternet network, fire-fighting private network interconnect.
A plurality of portable Mesh link terminals are taked to carry the mode of disposing while fighting by the fighter, and function is following:
1. possesses function with webmaster terminal data radio communication
2. the function that possesses the prompting of networking, suspension warning;
3. possess this Mesh of demonstration link terminal power supply power supply state, and show dump energy and operating time;
4. dynamically search and close on portable Mesh link terminal, set up the multiple wireless link, guarantee to be connected with the real-time of webmaster terminal;
5. possess 2 kinds of communication protocol handoff functionalities, guarantee the dual-use in wartime and non-wartime, increase network utilization to greatest extent;
6. be equipped with 3 road wireless blue tooth interfaces, dynamically accept the data (comprising: fighter's locator data, fighter's vital sign data, site environment data) of matching unit.
The beneficial effect of the utility model: native system is through the research to dijection frequency Mesh network technology; Set up fire-fighting emergent wireless communication network system based on dijection frequency Mesh network; Solved the awkward situation of public security fire-fighting army, realized the on-the-spot emergency communication support mission of fire fighting and rescue fire fighting and rescue on-the-spot " it is available not have net ".Native system has good emergency character, and the framework of network does not rely on on-the-spot environment; System has optimum utilance, and 2 sets of data communication protocols are provided, and guarantees wartime and non-wartime can both use native system and carry out data communication; System has the self-organization of network characteristic; Each Mesh via node can also independently be set up the function of route in the system except that responsible data communication, therefore under the situation that a data link opens circuit; Can search the link that other can be used automatically, guarantee the unimpeded of communication; Webmaster terminal in the system and portable Mesh link terminal all have the multichannel external interface, the assurance system can with being connected of external system, network, equipment.
System has and makes up characteristic rapidly, and the vehicle mobile equipment of using in the system adopts the vehicle power supply, and portable Mesh trunking volume is little, in light weight and independently-powered, so the assurance system can make up fast.
