Detailed ways

A tap water pipe burst monitoring system, including an automatic monitoring center and several main and branch pipeline monitoring stations, each station is equipped with flow and pressure sensors, and GPRS wireless transmission module is used for data transmission, and the pressure and flow data of the monitoring stations are passed through China Mobile's wireless network transmits to the designated industrial computer and displays it on the monitoring interface. Through the monitoring interface, the operator can grasp the real-time pressure data of the monitoring stations distributed in various places. When the pressure exceeds the set alarm limit, the monitoring system can Send out alarm information in time to notify the operator, and more quickly and accurately find the location and degree of a type of failure such as a tap water pipe burst. the

The tap water pipe burst monitoring system is adopted, which includes an automatic monitoring center, and multiple main pipeline sites and multiple branch pipeline sites are set in turn. Each site is equipped with a flow sensor and a pressure sensor to collect and feed back flow and pressure signals. By analyzing the feedback information, protection actions can be effectively carried out: when the flow and pressure signals collected by a certain station are abnormal, there will be a pipe burst failure in this section, and the system will automatically close the nearest valve in front of the pipeline in this section, and pass Sound and light alarm to prompt. the

Several main and branch pipeline stations are installed with: pressure sensors installed in the water supply pipe network of the monitoring station, connected with the GPRS wireless transmission module, used to detect the pipeline pressure signal of the station, and convert it into a 4-20mA current signal for feedback. The flow sensor is installed in the water supply pipe network of the monitoring site and connected with the GPRS wireless transmission module to detect the pipeline flow signal of the site and convert it into a 4-20mA current signal for feedback. The GPRS wireless transmission module is connected with the site sensors and the industrial computer of the automatic monitoring center, and is used to transmit the flow and pressure signals detected by each site. the

The monitoring process includes the following steps:

1. Start the industrial computer, set up the tap water burst monitoring system and store it;

2. Input and store the basic data of the pipe network;

3. The automatic monitoring center instructs the pressure sensors and flow sensors at each main and branch pipeline site to monitor water pressure and flow;

4. The sensor performs water pressure and flow measurement, collection and feedback according to the program instructions, converts the measurement data into 4-20mA current signals, and transmits them to the industrial computer through the GPRS data transmission module;

5. The automatic monitoring center analyzes the collected data sent back by the sensor, determines whether there is a burst fault in the water supply pipe network, and performs the location of the burst fault and the judgment of the fault degree. the

Compared with prior art, advantage and positive effect of the present utility model are:

1. High degree of automation, realizing unmanned automatic monitoring of pipe burst;

2. Adopt GPRS data transmission module, use mobile communication network for data transmission, which is more safe and reliable;

3. The distance between each station is about 1km, which can identify the accident point more accurately;

4. Through the monitoring system, the instantaneous pressure and flow of the pipe network at each station can be displayed, and the upper limit of the pressure of the pipe network can be set in advance. When the feedback signal reaches the upper limit of the pressure, the number of equipment running can be automatically reduced to protect the pipe network. Purpose. the

5. Through the analysis of the information fed back by the monitoring center, the protection action can be effectively carried out. When a certain section of pipeline burst is detected, the system will automatically close the nearest valve in front of the section of pipeline. the

Take a system of six monitoring stations as an example, as shown in the attached figure, the automatic detection center is set in the water supply dispatching room of the waterworks, and the stations are set up after a certain distance outside the waterworks, and three of the six stations are main pipelines Monitoring stations, the other three are branch pipeline monitoring stations, and the distance between the main pipeline monitoring stations is 1km. When the system is running, each monitoring station transmits the flow and pressure signals of each monitoring station back to the automatic monitoring center through the GPRS data transmission module, and the flow and pressure of each monitoring station can be seen through the configuration screen, and the system automatically compares and analyzes the received data. Signal, if the signal of any monitoring station fluctuates abnormally, the system will automatically close the nearest valve in front of the section of the pipeline, and send an alarm signal to indicate that the section of the pipeline is faulty, and the pipe may burst. the
