Problems solved by technology

[0009] The basis for judging the failure of a certain communication method or the disconnection of the network is not clear, which may lead to misjudgment, especially when the communication method is not smooth.
[0010] In the process of network disconnection judgment and restarting other communication methods, there may be a relatively long delay in the transmission of emergency information, and data loss may also occur
[0011] Affected by reliability requirements, the comm

Embodiment 1

[0147] Embodiment 1: as figure 1 , Figure 4 A communication method with complementary advantages of multi-master communication technology is shown, and the communication method includes the following steps:

[0148] Initialize the sending order and interval list and the latest receiving list, pre-set the sending order and interval list, and the latest receiving list, save the default sending order and sending interval, and clear the recent receiving list;

[0149] When the data to be sent is generated, the data to be sent is encapsulated into a datagram, which includes but is not limited to: the time when the data is generated, the sequence number of the data generation, the device number of the data generation, and the data content;

[0150] Record the encapsulated datagram;

[0151] According to the list of sending order and interval, the encapsulated datagrams are sent out from various communication means in turn, waiting for the host computer to reply;

[0152] The uppe...

Embodiment 2

[0187] Example 2: figure 2 The dynamic adjustment method of the data transmission time interval of three levels of communication means is shown:

[0188] After the step of counting the number of times of the three levels of communication means with no response, the following steps are also included:

[0189] Judging whether there is no response from the free means of communication;

[0190] If none of the free communication means responds, the sending interval of the general paid communication means is shortened proportionally, and the shortened value is: 10% × the number of consecutive non-response times of the free communication means, and the number of consecutive non-response times of the free communication means is not more than 8 times;

[0191] If there is a response from the free communication means, the transmission interval of the general fee-based communication means shall be restored to 100%; at the same time, the transmission interval of the high-charge communic...

Embodiment 3

[0210] Embodiment 3: as Figure 5 Shows methods of communicating by free, generally charged, and premium means of communication:

[0211] In the list according to the order of sending and the interval, the encapsulated datagrams are sent out from various communication means in turn, and after waiting for the upper computer to respond, the following steps are also included:

[0212] Determine whether the host computer supports WIFI communication means for data communication;

[0213] If the host computer does not support WIFI communication means data communication, it will automatically enter the next communication means LORA for data communication;

[0214] If the upper computer supports data communication by means of WIFI communication, send data from this communication means, and check whether the data communication response between the means of WIFI communication and the upper computer is correct;

[0215] If the response is correct, it is confirmed that the data has been...

Abstract

The invention discloses a communication method and device for advantage complementation of a multi-master communication technology, and relates to the field of Internet of Things communication transmission. The method comprises the following steps:. The method comprises the following steps: initializing a sending sequence, an interval list and a latest receiving list; communication means are graded, and the sending sequence and the interval list are dynamically optimized; when to-be-sent data is generated, packaging the to-be-sent data into a datagram; according to the sending sequence and theinterval list, the packaged datagrams are sequentially sent out from multiple communication means to wait for an upper computer to respond; if the response exists, comparing the response datagram with the information of the recently received list, If the same data record exists, not executing the action and only returning the corresponding response along the original path; If the same data recorddoes not exist, executing an action. Simultaneous work of multiple communication means and possible conflicts between data receiving and sending are realized, so that the multiple communication meanswork independently and do not influence each other; the communication method is high in speed, high in efficiency and low in cost.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things communication transmission, in particular to a communication method and device with complementary advantages of multi-master communication technology. Background technique [0002] In the practical application of IoT devices, because the network quality of mobile communication operators or telecom operators has a great relationship with the number of users, in uninhabited areas, urban-rural transition areas, underground tunnels, basements, underground parking lots, etc. In some occasions, the coverage of a single communication method often cannot meet the requirements of actual use, or the communication cost is too high, or the deployment cost is high, or the reliability and stability are not good enough to meet the actual needs of the Internet of Things; therefore, multiple (three A communication method that integrates communication means is an inevitable trend. [0003] At pr...
