Embodiment 1

[0062] refer to figure 1 As shown, the embodiment of the present application provides an automatic alarm method for online liquid level monitoring, which is used for liquid level monitoring and alarming in scenes such as rivers, lakes, reservoirs, urban drainage pipe networks, and manholes. The method includes the following steps.

[0063] Step S1: Read preset multiple collection cycles, communication cycles, liquid level parameters and parameters of alarm hysteresis.

[0064] refer to figure 2 As shown, the liquid level parameters in this step S1 include a warning liquid level line L1 and a safety liquid level line L2, wherein L2<L1<L0. Using the warning liquid level line L1 and the safety liquid level line L2, the liquid level state is divided from bottom to top into a safe liquid level state, a warning liquid level state, and a dangerous liquid level state.

[0065] refer to image 3 As shown, the alarm hysteresis parameters of the warning liquid level line L1 include:...

Embodiment 2

[0095] refer to Figure 7 As shown, the embodiment of the present application provides an automatic alarm system for online liquid level monitoring, using the automatic alarm method for online liquid level monitoring in the first embodiment, the system includes a monitoring terminal 300, a cloud server 200 and several liquid level alarm devices 100 ; the cloud server 200 is signally connected to the monitoring terminal 300 and the liquid level alarm device 100 respectively.

[0096] The monitoring terminal 300 is configured to access the cloud server to set or modify multiple acquisition cycles, communication cycles, liquid level parameters and their alarm hysteresis parameters of each liquid level alarm device, as well as monitor the current liquid level monitored by each liquid level alarm device. Bit status and alarm messages issued. The monitoring terminal 300 in this embodiment may be terminal devices such as a mobile phone terminal, a PC, a tablet, and a notebook.

Abstract

The invention discloses an online liquid level monitoring and automatic alarming method, system and device. The method comprises the following steps: S1, reading a plurality of preset collection periods, communication periods, liquid level parameters and alarm return difference parameters; S2, acquiring acquisition liquid levels D, comparing the acquisition liquid levels D with the liquid level parameters, and automatically adjusting an acquisition period and a communication period by utilizing comparison results based on a preset period adjustment strategy; and S3, acquiring a liquid level movement trend and a fluctuation range of the collected liquid levels D according to the plurality of obtained continuous collected liquid levels D, comparing the fluctuation range of the collected liquid levels D with each alarm return difference parameter to obtain the liquid level state of the fluctuation range of the current collected liquid level D, and sending alarm information based on a preset liquid level alarm strategy according to the liquid level state and the adjusted communication period. Alarm information can be sent in time, manual guard is reduced, the electric quantity of a battery can be effectively saved, and the service life of monitoring equipment is prolonged.

Description

technical field [0001] The invention relates to liquid level detection technology, in particular to an online liquid level monitoring and automatic alarm method, system and equipment. Background technique [0002] Liquid level monitoring equipment is mainly used for liquid level monitoring of rivers, lakes, reservoirs, urban drainage pipe networks, inspection wells, etc., especially for liquid level monitoring equipment installed in inspection wells. Due to its special installation environment, it cannot pass through mains or Solar energy provides the power and can only rely on batteries for power. [0003] In order to save battery power and ensure long-term operation of the equipment, the working mode of liquid level monitoring is mostly changed from real-time collection and monitoring to periodic work, that is, a fixed cycle is preset, the liquid level is once every other collection cycle, and every other communication Period, send the liquid level once. [0004] Traditi...
