Detailed Description
The river pollutant tracing method provided by the invention is further detailed and completely explained in the following by combining the embodiment. The following examples are illustrative only and are not to be construed as limiting the invention.
A river pollutant tracing method is disclosed, as shown in figure 1, a tracing device 8 patrols in a monitored river, when the tracing device 8 monitors that a certain pollutant index reaches an early warning value, the tracing device 8 navigates between two banks in a river by a broken line tracing line 10, and moves backwards, the maximum pollutant concentration in each line segment in the tracing line 10 is monitored and the GPS coordinate of the maximum pollutant concentration is recorded, when the tracing device 8 monitors that the maximum pollutant concentration in a certain line segment is lower than the maximum pollutant concentration in the previous line segment, the tracing device 8 monitors between the two maximum pollutant concentration points by the broken line navigation until the position of a pollution source 9 is obtained.
The river surface of the river can be regarded as a two-dimensional plane, the polygonal traceable route 10 is composed of a plurality of line segments which are sequentially connected between two banks, and the included angle between every two adjacent line segments is 10-30 degrees. Two ends of the first line segment are respectively a starting point of the tracing device 8 on the tracing line 10 and a certain point of one of the shore edges, and two ends of each of the other line segments are respectively located on two shore edges. Specifically, along the navigation route of the tracing device 8, the contact points of the tracing route 10 and the two banks are a first bank point 1, a second bank point 2, a third bank point 3, a fourth bank point 4, a fifth bank point 5, and so on; in other words, two ends of a first line segment of the tracing line 10 are respectively a starting point and a first shore point 1 of the tracing device 8, two ends of a second line segment are respectively a first shore point 1 and a second shore point 2, two ends of a third line segment are respectively a second shore point 2 and a third shore point 3, and two ends of a fourth line segment are respectively a third shore point 3 and a fourth shore point 4, and so on. The odd bank points and the even bank points are respectively positioned at two banks of the river channel. The maximum concentration points of pollutants in each line segment are connected and fitted into a curve-shaped pollutant line 11, the maximum concentration point of pollutants on the first line segment is a first highest concentration point 1 ', the maximum concentration point of pollutants on the second line segment is a second highest concentration point 2', the maximum concentration point of pollutants on the third line segment is a second highest concentration point 3 ', the maximum concentration point of pollutants on the fourth line segment is a fourth highest concentration point 4', and the like. From the first highest concentration point 1 'to the nth highest concentration point N' (N ═ 2, 3, 4, … …), the contaminant concentration at each point gradually increases. The contaminant line 11 may indicate the general direction of the source 9 in terms of a low to high contaminant concentration connection.
When the tracing apparatus 8 monitors that the maximum concentration of the contaminant in a certain line segment is lower than that in the previous line segment, it is verified that the contamination source 9 is between the two line segments. The tracing device 8 returns between the two maximum concentration points of the pollutants in a zigzag shape, continues to sail and monitor, and the range of the zigzag-shaped return line along the width direction of the river channel is the range of the pollutant line 11 along the width direction of the river channel, so that the searching range of the pollution source 9 can be reduced, and the determination time of the pollution source 9 can be shortened. Specifically, when the concentration of the nth highest concentration point n 'of the maximum concentration point of the pollutant on the nth line segment is monitored to be smaller than the concentration of the nth-1 highest concentration point n-1' of the maximum concentration point of the pollutant on the nth-1 line segment, the tracing device 8 stops continuing to move forwards and returns by using a broken line, the angle between each adjacent line segments of the broken line is 10-30 degrees, the maximum concentration point of each pollutant on the return line is monitored according to the advancing method, and when the maximum concentration of the pollutant on a certain line segment is monitored to be close to the maximum concentration of the pollutant on the adjacent line segment, the pollution source 9 is determined.
The source tracing equipment 8 comprises a tour ship body, a water quality sensor, a GPS positioning device, a local control system, a camera and a sampler, wherein the water quality sensor, the GPS positioning device, the local control system, the camera and the sampler are arranged on the tour ship body, and the local control system is remotely connected with an upper computer. The local control system can store the monitoring data of each pollutant concentration and each coordinate value and transmit each data to the upper computer. The local control system is preset with control logic and various parameter thresholds. The GPS positioning device is used for recording the coordinate value of the source tracing equipment 8 in the river channel. When the pollution source 9 is determined, the water flow where the pollution source 9 is located is sampled and GPS positioned.
The sampler comprises a water pump and a water tank, and the start and stop of the water pump are controlled by a local control system and an upper computer. The water pump pumps the contaminated water to the water tank. After the position of the pollution source 9 is obtained, a camera is used for shooting or photographing, and a polluted water flow sample near the pollution source 9 is obtained through a sampler.
Finally, it must be said here that: the above embodiments are only used for further detailed description of the technical solutions of the present invention, and should not be understood as limiting the scope of the present invention, and the insubstantial modifications and adaptations made by those skilled in the art according to the above descriptions of the present invention are within the scope of the present invention.
