Core processor：To obtain current location 4G signal intensities and be made whether forwarding judgement；
4G modules：The data collected from terminal are uploaded to Internet；
Low-power consumption wide area network access gateway module：Receive the data message that each low-power consumption wide area network termination is sent；
Memory module：When 4G network signals are not good, the temporary data being collected into, so as to the time slot communicated between the base stations Returned；
Routing module：Forwarding capability is realized, the data of this base station are transmitted to down according to the instruction that core processor is assigned One base station；
Power module：Electric power is provided for work in every operation；
Low-power consumption wide area network data acquisition of terminal is simultaneously uploaded to base station.
Mesh network passback is by low-power consumption wide area network skill between the low-power consumption wide area network termination access and base station Art is realized.
Beneficial effect：The present invention compared with prior art, has the following advantages：
(1) low-power consumption wan technology is used between low-power consumption wide area network termination of the invention and low-power consumption wide area network base station Communication, using point-to-point communication mode, realizes the purpose of long-distance transmissions, realizes data acquisition with cheap cost, simultaneously With it is low in energy consumption, signal penetrability is strong, sensitivity is high the characteristics of.
(2) present invention has fully used flexibility, the robustness of Mesh network, by multiple low-power consumption wide area network base stations it Between data transfer, uploaded, made whole according to the reasonable control data of the different 4G signal conditions of each low-power consumption wide area network base station System operation process is more reliable.The Mesh network being made up of simultaneously low-power consumption wan technology need not carry other networking modules, Power consumption can be preferably reduced, system operation is kept within the longer time.
(3) mode that access and Mesh network are returned is carried out by low-power consumption wan technology, mass data point can be gathered Data, and be reliably uploaded to service server in real time.The addition of multiple low-power consumption wide area network base stations, also allows accessible simultaneously Low-power consumption wide area network termination number increase at double, practical ranges are wider, are more suitable for the application in Internet of Things.
