Problems solved by technology

Therefore, we use a lot of bandwidth and storage space to save the data we don't need, which wastes actual resources and also causes some troubles for the screening of data analysis in the future
[0004] Some frequency conversion data transmission modes have been developed, but these frequency conversion modes can only artificially adjust the transmission frequency when the system is not running or running. After running, whether it is normal data or abnormal data, it will still be sent according to a fixed transmission frequency. , with almost no change from the traditional model

Embodiment Construction

[0023] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 The shown fire-fighting equipment data acquisition system of the present invention has a structure comprising: a data capture network formed by a plurality of data capture devices; a data acquisition and transmission device corresponding to each data capture device; Data integration, data processing, and data terminals at the application level corresponding to the man-machine interface.

[0025] Take the actual temperature acquisition as a case to explain how the whole system works:

[0026] We assume a common situation, assuming that in actual operation, we need to monitor the room temperature in the common low-voltage equipment room. According to national standards, the temperature in the machine room should be between 15°C and 25°C. Therefore, we set the range of 15°C-25°C as the threshold.

[0027] In the first step of the ...

Abstract

The invention provides a variable-frequency sampling system and a method thereof. The method includes: when there is no alarm event, capturing and uploading sensor data with low detection frequency in order to save storage resources and upload bandwidth resources; and after an alarm event occurs, capturing and uploading a sensor emitting an alarm and data of a related sensor thereof with high detection frequency in order to save related catastrophe data of a region with alarm to the maximum.

Description

technical field [0001] The invention relates to a system and a method for sending data by frequency conversion in the form of events in a fire-fighting equipment data collection system. More specifically, the present invention relates to a system and method for sending data with frequency conversion in the form of events based on traditional fire-fighting equipment data monitoring and data uploading systems. [0002] technical background [0003] Nowadays, while fire prevention and disaster prevention have become an important part of our life, countless equipment for fire safety are widely used. For example, we often place temperature sensors, humidity sensors, and smoke sensors in some important scenes or in rooms. , carbon dioxide concentration sensing, dust concentration sensing and other equipment for fire warning and protection, these devices will collect data through wired transmission or wireless transmission and send it to the monitoring room for detection by monitori...
