Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b): as shown in fig. 1-5, the present invention provides a distributed interconnection type data transmission method for wireless signal acquisition nodes, comprising the following steps:
s1: selecting a data transmission mode;
s2: deployment of hardware;
s3: determining a data transmission path;
s4: judging whether the data is credible;
furthermore, data transmission is directly carried out through a communication module arranged in the wireless signal acquisition node, the mode belongs to the mode that the nodes directly carry out information interaction, but the time interval of data uploading among multiple nodes is slightly different, so that the time for uploading the same group of equipment data to the server is not consistent; the gateway is used for establishing connection between two different networks of an internet of things sensing layer and a network layer to receive original data of equipment operation at the same time, which are acquired by a plurality of wireless signal acquisition nodes preset on the same equipment, the signal acquisition nodes on the bottom layer can be directly managed through the forwarding gateway, relevant information of the nodes is known, edge calculation is carried out on the collected original data while remote control is achieved, a calculation result is uploaded to a server according to a data uploading standard format, and consistency of data uploading time is guaranteed while calculation pressure of the server is relieved.
Furthermore, a plurality of wireless signal acquisition nodes are preset at different positions on the mechanical equipment, and a uniform acquisition strategy is issued to collect the operation data of the equipment, so that the plurality of wireless signal acquisition nodes are ensured to have the same sampling period and sampling frequency.
Further, selecting a corresponding data transmission channel and a corresponding transmission layer communication protocol according to different data transmission modes and judging the residual receiving windows of the nodes on the transmission path;
when data transmission is directly carried out through a communication module arranged in a wireless signal acquisition node, when the data uploading time exceeds the set time due to the fact that signal transmission is blocked in one of a plurality of wireless signal acquisition nodes, the data cannot be completely uploaded to a server, at the moment, a signal processing module arranged in the data non-uploading node can carry out screening, grouping and packing compression on a previous group of non-uploaded data, a more optimal data transmission path is selected again for uploading, the selected data transmission path can be any wireless signal acquisition node which has a residual data receiving window and is carrying out data uploading in a signal acquisition node network, and the communication module of the wireless signal acquisition node is used for forwarding the previous group of non-uploaded data;
the method comprises the steps of uniformly processing equipment operation data collected by a plurality of wireless signal collection nodes in the same time period in a forwarding gateway mode, firstly sensing the real-time state of each node by the gateway, obtaining the information such as the attribute and the state of each node, uniformly sending the original data collected by the wireless signal collection nodes to the gateway, not directly carrying out information interaction with a server by the nodes, carrying out data integrity inspection on the received data by the gateway during edge calculation, carrying out data transmission by a signal processing module arranged in the node in a similar way to the above-mentioned method by directly carrying out data transmission through a communication module arranged in the wireless signal collection nodes when the data of one of the plurality of received wireless signal collection nodes is incomplete, screening, grouping and packing the data which are not completely uploaded in the previous group by the signal processing module arranged in the node, and reselecting a data transmission path to upload to the forwarding gateway, the selected data transmission path can be any wireless signal acquisition node which has a residual data receiving window and is uploading data in a signal acquisition node network, a communication module of the selected data transmission path is used for forwarding the last group of data which is not uploaded to a gateway, the gateway carries out edge calculation, and a calculation result is uploaded to a back-end server according to a data uploading standard format;
when a data transmission path is reselected, the communication protocol, the data transmission length, the transmission time and the node residual receiving window need to be logically judged, and when all conditions are met, data forwarding and re-uploading can be carried out through other wireless signal acquisition nodes;
by the above method, the data of the wireless signal acquisition node still cannot be transmitted to the gateway or the server, and then the node communication module is judged to be incapable of normally receiving the signal.
Further, comprehensively judging whether the data finally received by the server is complete and effective according to the transmission path of the original data, the length of the decompressed data and the data uploading time;
for data which cannot be completely uploaded, the method firstly judges whether a signal transmission channel between a wireless signal acquisition node and a server or a gateway can realize stable information interaction or not according to a transmission path, and if the signal transmission channel does not exist stably, the wireless signal acquisition node takes the data as a carrier through other mutually connected wireless signal acquisition nodes and uploads the incomplete data;
the selected data transmission path may be any wireless signal collection node in the signal collection node network, which has a remaining data receiving window and is uploading data, and the communication module of the wireless signal collection node is used to forward the last group of data of the nodes which are not uploading data.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
