The method realizes 100% data returning success rate and supports no upper number limit of nodes. Multiple channels with different functions, namely an arbitration channel and an uploading channel are utilized for transmission. A plurality of mechanisms of data concurrency, data retransmission and data response are combined. An overtime automatic exiting mechanism is used. A reliable data transmission task can be finished through a lightweight structure without a protocol stack. According to the method, the arbitration channel is separated from the transmission channel, and no upper number limit of the nodes exists. Total time consumption after uploading finishing of the node is only related with the number of nodes. The method realizes the technical effects of reliable data transmission task through the lightweight structure without the protocol stack, no upper number limit of the nodes, data uploading by all nodes, and no easy information loss.
Description
Technical field
The present invention relates to information transmission processing field, in particular it relates to a kind of infallible data retransmission method for low rate wireless network.
Background technology
The typical networking mode Zigbee of low rate wireless network, owing to it is that the mode distributed by timeslice avoids wireless signal to conflict.But, needing to give the correct time when network exists bursty data, timeslice distribution mechanism may result in signal propagation delay, even loses.Reason is that every first nodes all can only could transmit data in the timeslice of oneself, and once there be multiple root node unexpectedly to carry out wireless data transmission simultaneously, then inherently there is air message conflict to thus result in information dropout.And for the wireless network of finite channel capacity, when data count off exceedes certain tolerance limit, if single channel transmission data, inherently there is packet loss problem.
In sum, present inventor is in realizing the embodiment of the present application in the process of inventive technique scheme, it has been found that above-mentioned technology at least exists following technical problem:

For solving above-mentioned technical problem, the embodiment of the present application provides a kind of infallible data retransmission method for low rate wireless network, described method includes: the execution flow process of A gateway and the execution flow process of B node, described method is applied in ZigBee wireless network, wherein, gateway execution flow process particularly as follows:
AS1: gateway powers on, system brings into operation, and monitors arbitration channel；Wherein, described system is the operating system that gateway is built-in, or the software program inside gateway；
AS2: gateway waits data upload requests, jumps to AS3 after receiving data；
AS3: after gateway resolves, if effectively request, jumps to AS4, otherwise jumps to AS2；
AS4: gateway handoff, to uploading channel, sends data and uploads permission order, and jump to AS5；
AS5: wait that first time presets countdown, if first time presets countdown and terminates, gateway does not receive the data uploaded, then retransmit and once upload permission order, starts second time and presets countdown；
AS6: second time is preset countdown and terminated, if not receiving the data uploaded, then jumps to AS8；
AS7: during waiting that first time presets countdown, if receiving the data uploaded, then terminate in advance to preset countdown, and the data received uploaded onto the server or store, and jump to AS8；
AS8: gateway handoff returns arbitration channel, continues to monitor, and will forward AS3 to the day after tomorrow receiving data；
The execution flow process of node particularly as follows:
BS1: node powers on, system brings into operation；Described system is the operating system that gateway is built-in, or the software program inside gateway；
BS2: checking for data needs to report, if having, jumping to BS3, otherwise jumping to BS2；
BS3: be switched to arbitration channel, by multiple mechanism, upper sending out is asked, and is switched to data and uploads channel, start countdown after being sent completely；
BS4: before countdown terminates, receives the grant commands of gateway, uploads data to gateway, jumps to BS6；
BS5: countdown terminates, it does not have receive the grant commands of gateway, returns BS2, and attempts again uploading；
BS6: remove from data transmit queue and sent data, and jump to BS2.
Further, the MAC Address of the described every node allowing order to include receiving.
Further, described default countdown is specially 200ms countdown.It is on the one hand mate with hardware chip that countdown 200ms is designed as, another aspect be count down time long will return inefficient, when count down time is shorter, it is easy to cause that the data uploaded have not enough time to receive, it is easy to lead to errors judgement.
Further, described arbitration channel monitors a upper request of data for gateway, only monitors arbitration channel during the gateway free time, and any node sends out data to gateway, all needs to send upload request toward arbitration channel；Described channel of uploading for uploading data, all of child node need to receive that gateway sends can upload license data after, just can upload data.
Further, described method data send operation and adopt the multiple system of data, and namely data send operation and comprise and continuously transmit 3 secondary data each time；Described method data send operation and adopt data re-transmitting system, and namely each bag data are sent completely, if receiving return in 200ms, then automatically re-execute and once send operation.
Further, described method is applied particularly in temperature measurement system of grain storage, and temperature measurement system of grain storage includes: controller and multiple sensor being arranged on grain heap surface and inside, the data acquisition this method between sensor and controller is transmitted.
The one or more technical schemes provided in the embodiment of the present application, at least have the following technical effect that or advantage:
