Embodiment 1

[0019] Such as figure 1 As shown, the compression method of the coal mine sensor historical data of the present embodiment includes the following steps:

[0020] (1) Obtain the current data of all sensors from the file generated by the mine security monitoring networking system as the current batch of sensor data, and then use the data obtained from the sensor real-time data table in the security monitoring networking system as the previous batch of data, if the sensor If there is no data in the data table, the current batch of sensor data will be stored in the real-time sensor data table and the sensor historical data table at the same time, in which the historical data table is only written, and the real-time data table is written after deletion, ensuring that the real-time data table only Store the data of a certain moment or batch of coal mine, otherwise, execute the next step;

[0021] (2) Compare the current batch of sensor data with the previous batch of sensor data in...

Embodiment 2

[0029] Such as figure 1 As shown, the compression method of the coal mine sensor historical data of the present embodiment includes the following steps:

[0030] (1) Obtain the current data of all sensors from the file generated by the mine security monitoring networking system as the current batch of sensor data, and then use the data obtained from the sensor real-time data table in the security monitoring networking system as the previous batch of data, if the sensor If there is no data in the data table, the current batch of sensor data will be stored in the real-time sensor data table and the sensor historical data table at the same time, in which the historical data table is only written, and the real-time data table is written after deletion, ensuring that the real-time data table only Store the data of a certain moment or batch of coal mine, otherwise, execute the next step;

[0031] (2) Compare the current batch of sensor data with the previous batch of sensor data in...

Embodiment 3

[0039] Such as figure 1 As shown, the compression method of the coal mine sensor historical data of the present embodiment includes the following steps:

[0040] (1) Obtain the current data of all sensors from the file generated by the mine security monitoring networking system as the current batch of sensor data, and then use the data obtained from the sensor real-time data table in the security monitoring networking system as the previous batch of data, if the sensor If there is no data in the data table, the current batch of sensor data will be stored in the real-time sensor data table and the sensor historical data table at the same time, in which the historical data table is only written, and the real-time data table is written after deletion, ensuring that the real-time data table only Store the data of a certain moment or batch of coal mine, otherwise, execute the next step;

Abstract

The invention discloses a sensor data compression method based on a coal mine safety monitoring networking system. A data compression algorithm is designed and realized in a data acquisition server (DTS) of a coal mine safety monitoring networking system, i.e., if the real-time value of a current sensor is the same as the previous value of the sensor, redundant storage is not carried out any more,and newly-added, updated and deleted sensor data are stored each time. According to the invention, after data of a certain sensor is lost or interrupted, the point supplementing operation can be automatically carried out, and the usability of the data is ensured.

Description

technical field [0001] The invention relates to a data compression method, in particular to a sensor data compression method based on a coal mine safety monitoring networking system. Background technique [0002] The coal mine safety monitoring contact network system collects the file data generated by the mine safety monitoring and monitoring system in real time. The data are mainly the real-time concentration of various environmental factors in the well (such as methane, carbon monoxide, oxygen, wind speed, air volume, etc.) )Wait. The data generation cycle ranges from 10 seconds to 30 seconds, and the amount of data at a time also ranges from 100-300 points. Calculated according to the data generation cycle of 10 seconds and 300 points, the accumulated data volume in a year is as high as 900 million, while This is only the data volume of a single mine. The coal mine safety monitoring network system often needs to access a large amount of coal mine data. It can be seen t...
