Scheduling management method based on field multi-measure wireless communication route equipment

Abstract

The invention relates to a scheduling management method based on field multi-measure wireless communication route equipment. The multi-measure wireless communication route equipment is a wireless communication system device integrating wireless self-organized network communication, CDMA / GPRS / 3G (Code Division Multiple Access / General Packet Radio Service / The 3rd Generation Telecommunication) mobile wireless network communication, an MCU (Microprogrammed Control Unit), a video session terminal and a global positioning satellite module. The wireless self-organized network communication is a multi-channel network, can be rapidly erected and removed. The distance among all nodes is in a local area network with radius of not more than 5 kilometers, and the band width can reach 50Mbit / s. The CDMA / GPRS / 3G is used as a standby network. The occupation conditions of all channels are different during the communication. The network occupancy rate of all channels can be detected in a real-time manner. The communication can be scheduled in a real-time manner to balance the occupancy rate of all channels. When the wireless self-organized network is accidentally interrupted, the route scheduling management enables the communication to be automatically switched to the CDMA / GPRS / 3G network. As the band width of the mobile wireless network is small, a small amount of important data only can be transmitted. The route scheduling management detects whether the wireless self-organized network is restored in a real-time manner, if yes, the route scheduling management enables the communication to be switched to the wireless self-organized network from the CDMA / GPRS / 3G mobile wireless network communication immediately. The whole system has high stability and high reliability.

Description

technical field [0001] The invention relates to the on-site multi-means wireless communication routing equipment system scheduling and management of each communication channel during use, so that the occupancy of each channel in the entire wireless network is balanced, the throughput of communication data is guaranteed to be the largest, and the probability of network communication blocking is reduced to the lowest. Background technique [0002] At present, domestic wireless communication generally adopts the base station method, and intermediate base stations are set up in places where wireless communication is required, and all terminal access points must communicate with each other through the intermediate base station, which places high requirements on the base station; The wireless network in the jurisdiction area will be paralyzed.

[0002] At present, domestic wireless communication generally adopts the base station method, and intermediate base stations are set up in places where wireless communication is required, and all terminal access points must communicate with each other through the intermediate base station, which places high requirements on the base station; The wireless network in the jurisdiction area will be paralyzed. The base station only forwards the communication scheduling management of each access terminal, and only performs simple scheduling management on each communication channel. The scheduling management method used is the principle of the nearest routing channel. As long as the source terminal is calculated The closest routing channel to the destination, regardless of whether the channel has a very high occupancy rate, and a new communication request is added to the channel, some channels are often idle, some channels are very congested, and the entire wireless network uses The efficiency is very low; in addition, the flexibility of this kind of network is also very low, it cannot be erected and removed anytime and anywhere, the construction cost is high, and the cycle is long

[0003] The purpose of the present invention is to solve the problems of unbalanced channel occupancy, low throughput, low reliability, difficulty in erection and removal, and high cost during WLAN communication.
