Specifically, the data collected by the mechanical equipment has the following characteristics: the importance degree of each type of data is distinguished, the sending priority is also in sequence, and the sampling period of each type of data is different. The memory area division method adopted is as follows:
the storage area is divided into an internal RAM area and an external Flash area.
In the internal RAM area, data are stored in a queue mode, data to be transmitted in the same type are stored together, data to be transmitted in different types are arranged according to sending priorities, and data to be transmitted in the same type and the same priority are arranged according to the time stamp sequence. That is, in the above embodiment, the data to be transmitted is stored in the predetermined storage area in the form of a queue according to the type, priority, data identifier, and timestamp of the data to be transmitted.

The storage management information area stores the latest management information in a circulating manner, and as shown in fig. 2, the management information includes information such as the start address of the data load area and the total size of the data load. The data load area contains various types of data, each data occupies a storage unit, the size of a unit is integral multiple of 16 bytes, and the length of the unit is variable.

Specifically, when the network is switched well, new data to be transmitted is generated, and at this time, the new data is transmitted preferentially, priority is guaranteed to be high, and when the new data arrives at the server at the first time and has an idle transmission bandwidth, old data is transmitted again, that is, data to be transmitted stored in the storage area is transmitted again. Therefore, the latest working state of the machine can be grasped at the first time, and after the old data is transmitted again, the supplementary calculation of an earlier time period is carried out.
