Referring to fig. 4, in another embodiment of the present application, the data information to be acquired further includes a storage address of the data to be acquired in the device to be acquired;
based on a first communication protocol, the method is communicated with equipment to be acquired to obtain acquisition data corresponding to data categories, and comprises the following steps:
s2301, based on the first communication protocol, sending a second data acquisition instruction to the device to be acquired, where the second data acquisition instruction carries a data category to be acquired and a storage address of the data to be acquired in the device to be acquired.
For convenience of description, the data acquisition instruction sent by the data acquisition terminal to the device to be acquired based on the first communication protocol is defined as the second data acquisition instruction. The second data acquisition instruction carries a data category to be acquired in the equipment to be acquired and a storage address of the data to be acquired in the equipment to be acquired, wherein the storage address corresponds to the data category to be acquired.
As an example, it is assumed that the first communication protocol is an RS-232 communication protocol, and in the first data acquisition instruction, the data category to be acquired included in the data information to be acquired is a utilization rate of a CPU, a total memory capacity and a memory utilization rate of a memory, a utilization rate, a total capacity and a partition format of a disk, and a temperature, a humidity and a PH value of a field where the device to be acquired is located; the storage address of the Data to be acquired in the Data information to be acquired, which corresponds to the Data category to be acquired, in the equipment to be acquired is C \ ProgramData \ MySQL \ MySQL Server 5.5\ Data \ Data.

correspondingly, uploading the acquired data to a cloud server comprises:
s2401, when the target data corresponding to the target data category does not meet the alarm threshold, sending an alarm prompt message to the cloud server, wherein the alarm prompt message carries the target data.
By way of example, assume that the data category to be collected is CPU utilization, total memory capacity and memory utilization of the memory, disk utilization, total capacity and partition format, and temperature, humidity and PH of the site where the device to be collected is located.
The target data category is the utilization rate of the CPU and the temperature of the site where the equipment to be acquired is located. Correspondingly, the alarm report list includes the utilization rate of the CPU and a first alarm threshold corresponding to the utilization rate of the CPU, the temperature of the site where the device to be acquired is located, and a second alarm threshold corresponding to the temperature of the site where the device to be acquired is located; wherein the first alarm threshold is different from the second alarm threshold.
It should be added that the CPU utilization is a time ratio of the CPU in a non-idle state in a unit time, which reflects how busy the CPU is, the CPU utilization is between 0% and 100%, and generally, the smaller the percentage value is, the higher the performance of the CPU in the device is, and if the CPU utilization is as high as 100%, it means that the performance of the CPU in the device is fully switched on, and the CPU high-load operation has reached the limit of the CPU performance, so that the device cannot be normally used (for example, it becomes abnormally stuck, halted, and loaded very slowly).
For example, assume that the first alarm threshold in the alarm report list is 80%, the second alarm threshold is 35 ℃, the CPU usage of the actually acquired device is 95%, and the temperature of the site where the device is located is 40 ℃. After the data acquisition terminal is determined through judgment, when the CPU usage rate (namely 95%) of actually acquired equipment exceeds 80% of a first alarm threshold value, and the temperature (namely 40 ℃) of the site where the actually acquired equipment is located exceeds 35 ℃ of a second alarm threshold value, the data acquisition terminal sends an alarm prompt message to a cloud server, wherein the alarm prompt message carries the actually acquired CPU usage rate and the temperature value of the site where the equipment is located, and the actually acquired CPU usage rate and the temperature value of the site where the equipment is located are target data in the embodiment of the application.

mode 2: the acquisition mode is that acquired data uploaded by all devices connected with the data acquisition terminal are integrated into a uniform file format and then uploaded to the cloud server;
mode 3: and in the edge computing mode, the data acquisition terminal analyzes, computes and stores the acquired data uploaded by the equipment at the data acquisition terminal, and finally uploads the processed data to the cloud server.
Different modes are set, different scenes in practical application can be solved in a targeted manner, and the mode 1 is equivalent to a long serial line or a data line to directly connect the equipment to the cloud server; when the mode 2 is adopted, the data acquisition terminal uploads the acquired data uploaded by all the devices to the cloud server after the formats of the acquired data are unified, so that the formats of the acquired data uploaded to the cloud server by different devices are unified conveniently; by adopting the mode 3, the system response speed and reliability can be effectively improved, the time delay is reduced, and the data volume of the cloud server is uploaded, so that the data flow consumption is reduced.

And S32, if the value is smaller than the first threshold value, storing the acquired data to the local.
By way of example, assuming that the first threshold is 100G, and the size of the data stored in the local storage space of the data acquisition terminal is 70G, the data acquisition terminal stores the acquired data locally.
And S33, when the data is larger than or equal to the first threshold value, the acquired data is stored to the first data in the local storage space in a covering mode, and the first data is the earliest acquired data stored in the local storage space.
