Underground pipe gallery spatial environment data collection method and system with failure judgment function

Abstract

The invention provides an underground pipe gallery spatial environment data collection method and system with a failure judgment function. The method comprises the steps of building a sensor failure judgment database; building an underground pipe gallery monitoring point event record database; receiving the environment data of each monitoring point fed back by a sensor module, calling event records of the corresponding monitoring point, and generating a second working range by combining with a normal variation amplitude of the sensor corresponding to the event and a first working range of the sensor; building a normal working database and an abnormal working database; providing a judgment module used for comparing a relation between a feedback result of the sensor and the second working range, and sending a collection result to the normal working database or the abnormal working database according to a judgment result. According to the method provided by the invention, influence factors of external environment and / or the external time to pipe gallery spatial environment data are introduced, and whether the collection result is within the normal working range is judged by comparison so as to judge whether the collection result is accurate, and whether the sensor is in a normal working state.

Description

technical field [0001] The invention relates to environmental data collection technology, in particular to a method and system for collecting space environmental data of an underground pipe corridor with fault judgment. Background technique [0002] The underground pipe gallery is equipped with various signal lines, heat pipes, gas pipes, telecommunication pipes, water supply pipes, power pipes, etc. It is a place where various signals and transmission objects meet. In order to fully ensure the environmental safety of the pipe gallery, it is necessary to The importance of monitoring the internal environment to achieve real-time and automatic monitoring of the environment in the underground pipe gallery is self-evident. [0003] In the existing technology, by configuring corresponding sensors and alarms in the underground pipe gallery, and leading the monitoring signal from the pipe gallery to the ground through communication, and transmitting it to the monitoring center thro...

AI Technical Summary

Problems solved by technology

[0004] The environment of the underground pipe gallery is harsh, and the sensors work in it. Some damage or abnormal work will inevitably occur. If these data are sent to the monitoring center together with the data during normal operation, the monitoring center needs to filter and extract the abnormal data. Information and normal data information, increasing the workload of monitoring personnel

[0005] In addition, the existing monitoring system does not take into account the impact of the external environment and / or external events on the environmental data, but the monitoring personnel still need to find the reason after the fluctuation of the collected data is found to be large, which increases the monitoring personnel from another aspect. workload
