Problems solved by technology

[0004] However, since the current security monitoring system can only alarm when the monitoring value reaches a certain fixed alarm value set, the alarm method is relatively rigid and single, and it cannot timely give early warning and analysis of abnormal dynamic changes in the monitoring value.
For example: in the current mine safety monitoring system, the set gas alarm value is 0.8%. The mine safety monitoring system can only alarm when the gas value reaches or exceeds 0.8%. If the gas value increases from 0.08 to 0.79% instantly, the safety monitoring The system cannot capture the information of abnormal gas changes in time
Therefore, the sensitivity of the existing technology to abnormal changes of the monitoring value is not high, and it cannot reliably ensure safe production operations.

Embodiment 1

[0024] figure 1 It is a flow chart of the early warning method provided by Embodiment 1 of the present invention. The method can be realized by an early warning system implemented by software and / or hardware, and specifically includes the following steps:

[0025] Step 110, collecting the current monitoring value;

[0026] In the above step 110, the current monitoring value is the dynamic data of the monitoring point monitored by various sensors during the production operation process, which can reflect the environmental condition of the monitoring point. For example, in the mine safety monitoring system, real-time monitoring data such as gas concentration monitoring value, carbon monoxide concentration monitoring value, wind speed monitoring value, temperature monitoring value, voltage monitoring value or current monitoring value of each mining head of the mine are monitored. The monitoring value of each monitoring point can be collected according to the set period.

Embodiment 2

[0034] The early warning method provided in Embodiment 2 of the present invention may be based on the early warning method of the above embodiment, specifically adopting the following early warning strategy as a scheme for judging whether to give early warning. The early-warning strategy is specifically the early-warning method of comparing the increment of the inspection cycle before and after. The so-called inspection cycle is: the length of time between two collection times, and the monitoring value is collected once in each inspection cycle. The inspection cycle setting can be the same as the cycle of each working face in the specific production operation.

[0035] Among them, the change value is generated according to the comparison between the current monitoring value and the recorded historical monitoring value, specifically: calculating the difference between the current monitoring value and the last collection time, that is, the monitoring value of the previous inspect...

Embodiment 3

[0046] The early warning method provided by the third embodiment of the present invention can be based on the early warning method of the above-mentioned embodiment, and specifically adopts the following early warning strategy of comparing average value increments as a scheme for judging whether to warn or not.

[0047] The step of generating a change value based on the comparison between the current monitoring value and the recorded historical monitoring value specifically includes:

[0048] Calculate the average value of the monitoring values ​​at each collection time of the previously set number;

[0049] The difference between the currently monitored value and this average value is calculated as the change value.

[0050] Taking the monitoring value of the gas concentration monitoring value as an example for illustration, the change value is compared with the preset threshold value according to the early warning strategy to generate early warning signals including:

Abstract

The invention provides an early warning method and an early warning system. The early warning method comprises the following steps of: collecting a current monitoring value; then, comparing the current monitoring value with a recorded history monitoring vale to generate a change value; and comparing the change value with a pre-set threshold value according to an early warming policy to generate an early warming signal. The early warning system comprises a collecting module for collecting the current monitoring value and an early warming judgment component for judging the early warming signal. According to the early warning method and the early warning system provided by the invention, the sensibility on abnormal condition change of the monitoring value is increased; the production and operation safety is increased; and particularly, the operation safety of coal mine enterprises is increased.

Description

technical field [0001] The invention relates to safety monitoring and monitoring technology, in particular to an early warning method and an early warning system. Background technique [0002] In the safety monitoring system, the most basic and most important function is to monitor the dynamic changes of the analog data at the monitoring point in real time, to give an alarm when the preset alarm value is reached, and to report to the security when the preset alarm value is reached or exceeded. The monitoring system sends out a control signal, so that the security monitoring system sends out an alarm sound, and an alarm window pops up at the terminal of the security monitoring system for alarming. [0003] For example, in the mine safety monitoring system, the most basic and important function is to monitor the dynamic changes of analog data such as gas, CO, wind speed and temperature at each mining head in real time, and to send an alarm when the preset alarm value is reache...
