Fig. 1 shows a structural block diagram of a multi-sensor based water regime monitoring and early warning system provided by the utility model. As shown in Figure 1, the utility model provides a water regime monitoring and early warning system based on multiple sensors, including: at least one data acquisition module; a device side wireless communication module, which is connected to the data acquisition module; a central side wireless communication module, It is connected to the wireless communication module on the equipment side; the control module is connected to the wireless communication module on the central side; the early warning module is connected to the control module; wherein, the data acquisition module includes: a temperature sensor, a water level sensor and a rainfall The temperature sensor, the water level sensor and the rain gauge sensor are connected to the control module through the equipment side wireless communication module and the center side wireless communication module.

Further, the utility model also includes: an urban grid structure, which includes at least one grid node, wherein: at least two of the data acquisition modules and the device-side wireless communication module are arranged in the grid node, The data acquisition modules in the same grid node are respectively connected to the same wireless communication module.

Further, the temperature sensor is a DS18B20 temperature sensor; the water level sensor is a LC-SW1 water level sensor; and the rain gauge sensor is a JDZ05-1 tipping bucket rain sensor. After a large number of realizations, it has been shown that the combination of the above sensors can effectively implement monitoring, and the energy consumption is very low.

Further, the temperature sensor is a DS18B20 temperature sensor; the water level sensor is a LC-SW1 water level sensor; and the rain gauge sensor is a JDZ02-1 tipping bucket rain sensor. After a large number of realizations, it has been shown that the combination of the above sensors can effectively implement monitoring, and the energy consumption is very low.

Further, the device-side wireless communication module and the center-side wireless communication module adopt the GPRS wireless communication protocol.

In order to monitor the water regime information of the whole city, various temperature sensors, water level sensors and rainfall sensors with different accuracy are deployed in different measurement media. In the temperature data module, a one-line digital temperature sensor DS18B20 temperature sensor can be used to realize multi-point temperature measurement and convert the measured temperature into a digital signal. The LC-SW1 water level sensor can be used in the water level data acquisition module, which has strong anti-interference and good long-term stability. It adopts HART communication protocol to realize digital signal transmission. In the rainfall data acquisition module, JDZ05-1 and JDZ02-1 tipping bucket rainfall sensors can be used to monitor urban rainfall. The sensors are deployed in different areas and are used simultaneously to monitor different types of hydrological data in the area regardless of the weather. If it is fine weather, the real-time data in the data packet sent by the rain sensor is 0. As shown in Figure 2, the entire city is divided into different areas in the form of a grid. According to the location of the Control Center (CC), the entire city is divided into Northwest (NW), Southwest (SW), and Northeast (NE) and Southeast (SE) four major regions. Each partition is assigned a unique identification code ID, such as NW1, SW1, etc., and each sensor is deployed in a different partition to collect data. The communication structure of the whole system is shown in Figure 3, and the GN in the figure is the grid node (Grid Node). Sensor nodes that are closer to the control center will send their data directly to the control center, such as nodes in area 4 in Figure 3, while nodes that are farther away from the control center will communicate with the control center through grid nodes, as in Figure 3 Zone 1, Zone 2, and Zone 3. When two adjacent areas are at the boundary of the four major areas of the city, they share a junction grid node, for example, area 2 and area 3 are near the junction of urban SW and SE. That is to say, according to the coverage area d of the communication module, set the sensor nodes within a certain distance d from the control center to communicate directly with the control center, and the sensor nodes beyond the distance d will communicate with the control center through grid nodes.

In order to improve the speed of water regime information acquisition and transmission, the equipped wireless communication module uses GPRS wireless communication technology to connect multiple remote terminal monitoring devices with the control center to realize the exchange of monitoring data. Divide the whole city into a grid, and set a node at each grid point to be responsible for the data sending and receiving work in the grid area. Then the grid nodes send the data directly to the control center. GPRS wireless communication encapsulates the data collected by the sensor into packets and transmits them through the antenna connected to it. In order to avoid data conflicts, each data packet includes destination address information and source address information, and the source address information includes the ID of the area where the sensor is located and the ID number of the sensor itself. In order to prolong the service life of the sensor and improve the quality of data transmission, a grid node is set at the grid point of each partition to receive and integrate the monitoring data in the area, which is responsible for the regional schematic diagram, as shown in Figure 3, except Except for the control center and the grid nodes on the azimuth boundary, the rest of the grid nodes are only responsible for the collection and transmission of data in one partition. In general, the grid nodes classify the received data into different data packets according to the data types, and integrate them into one data packet and send it to the control center regularly, but when the collected data level is at the warning level, it is not subject to periodic monitoring. sending limit. After the control center receives the water regime data packets sent by each area, it sends a clear command to each grid node through its equipped GPRS communication module box, so that the grid node can start the next round of data sending and receiving work.

The control module is mainly responsible for coordinating the sensors to collect water regime information in the monitoring area, analyzing and processing the collected information, and sending the processing results to the information release and early warning module.

The control module is mainly responsible for processing the water regime information collected by each sensor in the monitoring area, using GPRS wireless communication to manage multiple terminal monitoring devices, and completing the water regime information, that is, the temperature, water level and rainfall intensity of the monitored area. collection monitoring. The control center classifies and processes the collected data according to the area and data type. When the temperature T in the monitoring area rises, the water circulation accelerates to increase the evaporation, and the humidity increases, so the precipitation P in the area also increases. The process of processing the data after the control center receives the regional water regime data sent by each grid node. Due to the different topography and water conservancy facilities in various urban areas, the consequences of the same rainfall intensity are also different. Therefore, the judgment of warning data The thresholds are also different, and the impact indicators take the lower limit of the average value of historical impact data. According to the level of temperature, water level and rainfall data, the control center makes safety and alert judgments respectively, and sends the results to the information release and early warning module.

The information release and early warning module is mainly used to display the regional processing results of the control module, respectively display the water regime information in each area of the city, and quickly publish the urban water regime information and possible flood and waterlogging disaster information to the public through the network, for Urban flood control dispatching provides decision-making basis, and corresponding defense measures are taken in time to reduce disaster losses.
