Therefore, the data reliability is improved, the burden of the monitoring host is reduced, and the reliability and the robustness of the monitoring network are enhanced.
And 103, uploading the data which does not need to be processed or the processed data to a background to a server by the cache database periodically.
It should be noted that the cache database periodically uploads the data that does not need to be processed or the processed data to the server, and the background server stores the data sent from the gateway into the background database after monitoring the data, thereby completing the whole monitoring process.
The protocol conversion method comprises the steps of establishing a cache database at a monitoring protocol converter, handing responsibility of data acquisition from equipment to the protocol converter, enabling the protocol converter to be responsible for high-density data acquisition and polling, storing the acquired data into the cache database, enabling the protocol converter to have another program, and uploading the unprocessed or processed data of the database to a server at regular time. When the network oscillation is unstable or the network is temporarily disconnected and the like, the data are stored in the cache database, so that the data cannot be lost. And processing the local site data through the protocol converter relieves the multi-process burden of the server. The server only needs to store the uploaded data into a database of the server.

Step 202, collecting data through a monitoring protocol converter, polling monitoring equipment, and processing the collected data;
it should be noted that Polling (Polling) is a way for the CPU to decide how to provide services for peripheral devices, and is also called "Programmed input/output" (Programmed I/O). The concept of the polling method is: the CPU sends out inquiry at regular time to inquire each peripheral equipment whether it needs its service or not in sequence, if so, the peripheral equipment gives service, and after the service is over, the peripheral equipment asks the next peripheral equipment, and then the process is repeated. It can be understood that the present embodiment polls a plurality of monitoring devices by the monitoring protocol converter, and whether a service for collecting data is required.
Step 203, storing the acquired data or the processed data into a cache database;
it should be noted that the data collected by the monitoring protocol converter may be directly sent to the cache database for storage, or the collected data may be sent to other processing units for processing, and then sent to the cache database for storage.
And step 204, when the network is vibrated or temporarily interrupted, the cache database returns corresponding data after responding to the data request instruction.
It should be noted that, if the network is in a shock or is temporarily interrupted, the recent data is stored in the gateway cache database, so that no data is lost. In addition, when the cache database uploads the data, the data can be simply preprocessed according to needs and then uploaded.
