Fig. 2-3 are schematic flow charts of a first embodiment of a water level early warning method for a sewer line according to the present invention. In this embodiment, the method for warning the water level of the sewer line includes the following steps:
s1, acquiring target information, and judging whether the flowmeter meets a starting condition according to the target information, wherein the target information comprises position information of the sewer pipeline and weather information corresponding to the position information;
it should be understood that, in the present invention, the main implementation body is a water level early warning device applied to the sewer pipe, the water level early warning device of the sewer pipe includes a flow meter not shown in the figure, a radar level gauge not shown in the figure and a processor not shown in the figure, the flow meter and the radar level gauge are both connected with the processor, the flow meter is arranged in the sewer pipe, and the radar level gauge is arranged at the top of the sewer pipe. The sewer pipeline refers to an urban underground water pipe, and therefore, corresponding flow meters and radar water level meters are arranged in the sewer pipelines of different sections. Because the flowmeter is arranged in the sewer pipeline, in order to ensure the stability of signal transmission of the flowmeter, the flowmeter can transmit signals to a processor in the water level early warning device of the sewer pipeline through a cable or a network, and the connection mode of the flowmeter and the processor is not limited to the mode and can be set according to actual conditions. Similarly, radar level gauge is through setting up in sewer pipe top, in order to guarantee radar level gauge's signal transmission's stability, and radar level gauge accessible cable or network are not only limited to so with the treater among the water level early warning device of signal transmission to sewer pipe, the connected mode of radar level gauge and treater, can set up according to actual conditions. The water level early warning device is vertically arranged at the top of the sewer pipe, the radar water level gauge is arranged on the water level early warning device and is also vertically arranged at the top of the sewer pipe, and the distance between the radar water level gauge and the sewer pipe is set according to actual conditions.
Because the flowmeter is arranged in the sewer pipe, a corresponding power supply needs to be configured for the flowmeter, when the electric quantity of the power supply is exhausted, the power supply needs to be replaced or charged, but the replacement or charging of the power supply is troublesome, and in order to reduce the times of replacement or charging of the power supply, the time for consuming the power supply needs to be prolonged. To this end, when the water level early warning of sewer pipe needs to be carried out, the flowmeter is started, and when the water level early warning does not need to be carried out, the flowmeter is closed, and resources are saved. Similarly, the radar water level gauge is also turned on when early warning is needed and turned off when early warning is not needed, so that resources are saved.
The method comprises the steps of obtaining target information, and judging whether a flowmeter meets a starting condition according to the target information, wherein the target information comprises position information of a sewer pipeline and weather information corresponding to the position information; judging whether the weather information corresponding to the position information is rain and snow weather or not, if so, determining rainfall and determining preset rainfall corresponding to the position information; and when the rainfall is greater than or equal to the preset rainfall, judging that the flowmeter meets the starting condition.
It should be understood that the water level early warning device of the sewer acquires the position information corresponding to the sewer pipeline, the geographical position where the sewer pipeline is located is determined according to the position information, and then the current weather information corresponding to the geographical position is acquired, when the weather information is judged to be rainy or snowy weather, much rainwater enters the sewer pipeline, the waterlogging condition may occur, and at the moment, the rainfall is necessarily monitored. The different districts, sewer pipe's height also is different, and rainfall is lower sometimes, and the waterlogging also can appear in the place that the topography is low, consequently, it is necessary to predetermine the rainfall to the district that each sewer pipe corresponds, and the lower the district, the less the rainfall of predetermineeing, if the real-time rainfall that the rainfall of predetermineeing that this district corresponds is greater than or equal to this district appears, then the waterlogging probably appears, then open the flowmeter, this time the water level early warning device in the sewer pipe can judge that the flowmeter satisfies the start-up condition.
The method comprises the steps of obtaining target information, and judging whether a flowmeter meets a starting condition according to the target information, wherein the target information comprises position information of a sewer pipeline and weather information corresponding to the position information; acquiring image information of a road section where the sewer pipeline is located according to the position information of the sewer pipeline; and judging whether the road section has a road cleaning condition or not according to the image information, and if so, judging that the flowmeter meets a starting condition.
It should be understood that the water level early warning device of the sewer pipeline further comprises an image acquisition module, wherein the image acquisition module is arranged at the road section for monitoring the image information of the road section, and the road section corresponds to the sewer pipeline.
The image acquisition module can be the camera also can be other instruments that can gather the image, the water level early warning device of sewer pipe can judge whether there is the road washing condition in the highway section through the image information that the image acquisition module gathered, that is, whether have sanitary workman or sanitation car to wash the road, when wasing, debris on the road, dust can communicate rivers together and flow into sewer pipe, because the dust gets into sewer pipe, can make sewer pipe siltation mud, thereby make water unable discharge, at this moment, also need carry out sewer pipe's water level early warning.
Acquiring target information, and judging whether a flowmeter meets a starting condition or not according to the target information, wherein the target information comprises position information of the sewer pipeline and weather information corresponding to the position information; and acquiring a preset time period corresponding to the position information according to the position information of the sewer pipeline, judging whether the current time point belongs to the preset time period, and judging that the flowmeter meets the starting condition when the current time point belongs to the preset time period.
It should be understood that the sewer line can drain domestic water, which can also form waterlogging when there is a lot of domestic water. The discharge of domestic water has a certain time law. For example, from 7 pm to 9 pm, each family in a community starts to take a bath and wash clothes, and a large amount of domestic water is discharged when taking a bath and washing clothes. Therefore, the water level early warning device of the sewer pipeline stores the preset time period corresponding to the position of each sewer pipeline, and in the preset time period, the discharge amount of domestic water is large, so that the water level in the sewer pipeline needs to be monitored. And the water level early warning device of the sewer pipeline determines the time period of the current time point, judges whether the time period of the current time point is a preset time period, and if so, starts the flowmeter to monitor the water level in the sewer pipeline.
The invention provides various conditions for judging the opening of the water level gauge, and has wide coverage and strong operability; in rainy and snowy weather, the drainage pump is started in real time by monitoring rainfall, so that waterlogging can be effectively avoided; when the road section is cleaned, sundries can enter a sewer possibly, the sewer can deposit sludge, and the flowmeter is started to effectively remove the sludge and reduce the possibility that water cannot be discharged; when domestic water is more, waterlogging may appear, sets up the preset time quantum and monitors domestic water, controls opening of drain pump, can reduce the possibility of waterlogging.
S2, when the flowmeter meets the starting condition, starting the flowmeter, and acquiring the water flow in the sewer pipe collected by the flowmeter;
it is worth noting that when the flow meter meets the starting condition, the processor in the water level early warning device of the sewer pipeline sends a starting instruction to the flow meter, so that the flow meter is started, and further the flow meter collects the water flow in the sewer pipeline.
It should be noted that the water flow rate can represent the water flow velocity, the larger the water flow rate is, and the larger the water flow rate is, the more the accumulated water on the ground surface is, so that the accumulated water source can flow to the sewer pipeline without stopping. Therefore, in the present invention, it is possible to monitor whether or not water in the sewer pipe can form waterlogging by the flow meter.
S3, setting a water flow threshold value, and when the water flow collected by the flowmeter is larger than the water flow threshold value, outputting a first early warning signal to a remote monitoring center by the water level early warning device, and controlling a drainage pump of the sewer pipeline to forcibly run.
It is worth noting that a water flow threshold value is set, when the water flow collected by the flowmeter is larger than the water flow threshold value, the water level early warning device outputs a first early warning signal to the remote monitoring center, controls the draining pump of the sewer pipeline to forcibly run, sets a draining pump running time threshold value, when the draining pump running time is larger than the running time threshold value, the water level early warning device judges whether to output the first early warning signal to the remote monitoring center or not, and if the first early warning signal is output, the draining pump is controlled to continue to run until the water level early warning device does not output the first early warning signal any more.
In the invention, the water flow threshold is set, and can be any appropriate value and set according to the actual situation. When the water flow collected by the flowmeter is larger than a water flow threshold value, the water level early warning device outputs a first early warning signal to the remote monitoring center and controls a drainage pump of a sewer pipeline to forcibly run.
The drainage pump running time threshold is set, when the drainage pump running time is larger than the running time threshold, the water level early warning device judges whether to output a first early warning signal to the remote monitoring center or not, if the first early warning signal is output, the drainage pump is controlled to continue to run until the water level early warning device does not output the early warning signal any more, the drainage pump can be prevented from being used all the time, and the cost is saved.
And S4, when the water flow collected by the flowmeter is smaller than or equal to the water flow threshold, starting the radar water level gauge, acquiring the water level height of the sewer pipe, setting the water level height threshold, and when the water level height is higher than the water level height threshold, outputting a second early warning signal to the remote monitoring center by the water level early warning device, and controlling the draining pump of the sewer pipe to forcibly run.
It will be appreciated that the sewer line of each segment is provided with a drain pump.
