The water supply network is an indispensable link in urban water source supply, not only meets the requirements of people for drinking and other daily use, but also provides for fire protection and use in various critical conditions, and is one of life line systems for survival of cities. Therefore, in order to provide a good environment for normal water supply in cities, the safety and reliability of the operation of the water supply network must be ensured. However, most water supply systems in China are built at the end of the 20 th century, and most urban water supply networks in China are at the critical point of service life according to the related data of China's water conservancy and hydropower science institute. Because the service life is too long, the water supply network often bursts and leaks, not only causes water source and energy consumption, but also improves water supply cost, makes road and building have serious safety risk, and also easily causes secondary pollution.

At present, a water leakage point is usually detected by a related leak detection method, and the basic principle is as follows: vibration caused by the water leakage point propagates to two sides along the pipeline, and the sensors placed at different distances on the two sides receive sound waves emitted by the water leakage point at a certain moment, and the time difference is determined by the sound velocity of the pipeline and the position of the leakage point.

The sensors used in the related leak detection method in the market are all acoustic wave sensors formed by piezoelectric crystals, but the sensors need to be adsorbed on a pipeline through a magnet to detect a leak point, the detection distance can only reach 200 meters at most, the detection precision is low, the sensitivity is low, and the monitoring and early warning can not be carried out on a water supply pipeline, so that a detection device with higher sensitivity and simultaneously capable of monitoring and early warning is needed.

Examples

As shown in fig. 1-2, the utility model provides a monitoring and early warning system based on laser number acquisition, which comprises a water supply pipeline 1, wherein a plurality of reflecting mirror surfaces 5 are arranged on the water supply pipeline 1. The outside of the water supply pipeline 1 is provided with a plurality of laser probes 2, namely, the water supply pipeline network is provided with the laser probes 2 with proper intervals, so that a monitoring network can be formed, and the water leakage condition of the water supply pipeline network can be monitored in real time. The laser probe 2 is arranged at a distance from the water supply pipeline 1 and can be measured in a contactless manner. The measuring distance of the laser probe 2 is longer, the accuracy is higher, and the reflecting mirror surface 5 is arranged corresponding to the laser probe 2, a laser spot is struck to the reflecting mirror surface 5 through the laser probe 2, the laser spot is reflected back, and then the reflected signal is received through the signal transmitter 3. Each signal transmitter 3 is connected to a laser probe 2.

The laser probe 2 is all connected with the signal transmitter 3 in a communication way, the signal transmitter 3 comprises a data acquisition module 31, a positioning module 32 and a first communication module 33, the output ends of the data acquisition module 31 and the positioning module 32 are all connected with the input end of the first communication module 33, and the signal transmitter 3 is respectively connected with the monitoring host 4 in a communication way.

The monitoring host 4 comprises a data analysis module 41, a control module 42, an early warning module 43 and a second communication module 44, wherein the output end of the first communication module 33 is connected with the input end of the data analysis module 41, the output end of the data analysis module 41 is connected with the input end of the control module 42, and the output end of the control module 42 is connected with the input ends of the early warning module 43 and the second communication module 44.

For example, whether the water supply pipeline is abnormal or not can be detected between the A monitoring point and the B monitoring point, between the A monitoring point and the C monitoring point, and between the C monitoring point and the D monitoring point within the monitoring distance allowable range. Under the condition that the A monitoring point and the B monitoring point and the A monitoring point and the C monitoring point have overlapping parts, when abnormal signals are all present in the overlapping parts and in the same place (marked as W), the abnormal range can be locked to the W; when no abnormal signal appears in the overlapped part, the abnormal range can be locked to the non-overlapped part (namely, W is eliminated), and the abnormal range of the water supply pipeline is reduced. In practical application, more monitoring points are arranged, so that a water supply pipeline monitoring network is formed, and the abnormal condition of the water supply pipeline network is monitored in real time.
