[0002] During the rainfall process, the pollutant content in the runoff formed by the initial rainwater is the highest in the entire rainfall process. In the process of urban construction, more and more rivers use ecological slope protection. On both sides of the river channel with ecological slope protection, the surface and air pollutants mixed in the initial rainwater are discharged into the river through the surface runoff of the slope. Especially for sensitive water bodies such as water source protection areas, there is a certain pollution risk. Therefore, it is particularly important to conduct research on the impact of initial rainfall runoff pollution on river water bodies.

[0003] In the process of conducting research on runoff pollution in the early stage of rainfall, it is first necessary to collect runoff rainwater in the early stage of rainfall. At present, most scenarios for collecting rainwater are to sample rainwater collected by the rainwater pipe network after a rainfall event. In related technologies, some sampling methods can only achieve quantitative collection, and sampling personnel are required to arrive at the sampling point in advance according to the weather forecast to wait for rainfall, so as to achieve timed and quantitative runoff rainwater collection. However, the starting sampling time of this method is greatly affected by human factors; some sampling methods are automatic sampling, but sampling is mostly carried out at the beginning of rainfall, which makes it difficult to accurately study the pollution situation in the runoff.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] In the related art, when sampling runoff on both sides of the river channel with ecological slope protection, some sampling methods can only realize manual quantitative collection. For example, sampling personnel are required to arrive at the sampling point in advance according to the weather forecast and wait for rainfall. At the beginning of rainfall, the sampling container is placed at the sampling point to realize quantitative collection of runoff rainwater. However, the starting sampling time of this method is greatly affected by human factors. Therefore, the judgment of runoff formation is relatively subjective, and it is impossible to accurately sample the runoff at the beginning of rainfall; some sampling methods are automatic sampling, but sampling is mostly carried out when the beginning of rainfall is monitored, which makes it difficult to accurately judge whether runoff is formed, and it is impossible to accurately sample the runoff at the beginning of rainfall.

[0028] The embodiment of the present invention provides a runoff sampling system, which monitors surface runoff through a runoff monitoring module to improve the runoff collection efficiency.

[0029] In this embodiment, a runoff sampling system is provided. Figure 1 is a schematic diagram of the structure of a runoff sampling system according to an embodiment of the present invention. Figure 1 As shown, the process includes the following structure:

[0030] The runoff monitoring module 101 is used to monitor the surface runoff in the target sampling area to generate runoff formation information, and to send the runoff formation information to the control module 102; wherein the runoff formation information includes the instantaneous flow rate of the runoff, and the runoff monitoring module 101 is arranged in the target sampling area; the runoff monitoring module 101 is communicatively connected with the control module 102.

[0031] The target sampling area may be both sides of the river channel with ecological slope protection. The runoff monitoring module 101 is provided with a surface runoff sensor, which records the instantaneous flow and time of the runoff when the runoff is formed at the initial stage of rainfall, and generates runoff formation information.

[0032] In some optional implementations, the runoff formation information represents information used to determine runoff formation, including the instantaneous flow rate of the runoff and the time corresponding to the instantaneous flow rate of the runoff.

[0033] In some optional embodiments, the communication connection is a communication method between connected devices through signal transmission interaction, including wired connection and wireless connection, so that data transmission and interaction can be performed between devices. Exemplarily, the runoff monitoring module 101 and the control module 102 of the embodiment of the present invention are connected via wireless communication.

[0034] The control module 102 is used to generate a runoff collection signal according to the runoff formation information, and to send the runoff collection signal to the initial rainfall runoff collection module 103; wherein the initial rainfall runoff collection module 103 is arranged in the target sampling area; the control module 102 is communicatively connected with the initial rainfall runoff collection module 103.

[0035] The runoff collection signal refers to a signal used to issue a runoff collection instruction.

[0036] In some optional implementations, the control module 102 is used to determine the formation of runoff and generate a runoff collection signal according to the instantaneous flow rate of runoff in the runoff formation information.

[0037] When the instantaneous flow rate of runoff is greater than or equal to a preset value, it is determined that runoff is formed.

[0038] In some optional implementations, the control module 102 is connected to the initial rainfall runoff collection module 103 via wireless communication.

[0039] The initial rainfall runoff collection module 103 is used to perform runoff sampling on the target sampling area according to the runoff collection signal; wherein the runoff collection signal includes one or more of a start sampling instruction, a stop sampling instruction and a collection time interval.

[0040] In some optional embodiments, the control module 102 generates a collection time interval based on a pre-set collection time interval generation algorithm, and generates a collection time interval according to a start sampling instruction and a stop sampling instruction. For example, the start sampling instruction: start collection immediately; the stop sampling instruction: stop collection after 30 minutes. Based on the collection time interval generation algorithm, a collection time interval of 5 minutes is automatically generated.

[0041] Among them, the initial rainfall runoff collection module 103 is set in the target sampling area and receives the runoff collection signal sent by the control module 102. The initial rainfall runoff collection module 103 is used to perform runoff sampling on the target sampling area according to one or more of the start sampling instruction, stop sampling instruction and collection time interval in the runoff collection signal.

[0042] In some optional embodiments, the initial rainfall runoff collection module 103 determines that the runoff collection signal includes a start sampling instruction, a stop sampling instruction, and a collection time interval. The initial rainfall runoff collection module 103 starts runoff sampling according to the collection time interval according to the start sampling instruction, and stops runoff sampling according to the stop sampling instruction.

[0043] Exemplarily, the runoff collection signal includes a start sampling instruction: start collection immediately; a stop sampling instruction: stop collection after 30 minutes; and a collection time interval: 5 minutes. Then, the initial rainfall runoff collection module 103 immediately collects at a time interval of every 5 minutes and stops collecting after 30 minutes.

[0044] In some optional implementations, the initial rainfall runoff collection module 103 includes a plurality of water collection containers, and the control module 102 is further configured to switch the use of the plurality of water collection containers in the initial rainfall runoff collection module 103 according to the received container use information.

[0045] The container usage information indicates the container information that is preset and put into use.

[0046] Exemplarily, the initial rainfall runoff collection module 103 includes 6 containers with a capacity of 1 liter and volume scales. The container usage information received by the initial rainfall runoff collection module 103 is to switch the container every 5 minutes. Therefore, during the runoff sampling process, the initial rainfall runoff collection module 103 switches the current container to the next container every 5 minutes.

[0047] In the embodiment of the present invention, the control module 102 can determine the change of runoff flow within a preset time period after the formation of rainfall runoff based on the volume of runoff collected by the initial rainfall runoff collection module 103 and the instantaneous runoff flow monitored by the runoff monitoring module 101. The preset time represents the time period from the start sampling instruction to the stop sampling instruction.

[0048] In the embodiment of the present invention, water quality monitoring is performed on water samples in multiple containers to obtain the change of water quality of slope runoff within a preset time period after the formation of rainfall runoff. Further regularity research on pollution load can be carried out based on water quality and water quantity. By combining and arranging multiple runoff sampling systems on the slope, the spatial variation law of pollution load of surface runoff on the slope at the initial stage of rainfall can be studied.

[0049] The runoff sampling system provided in this embodiment includes a runoff monitoring module 101 arranged in a target sampling area, which is used to automatically sense the formation of runoff and generate runoff formation information including the instantaneous flow rate of runoff. It can determine whether runoff is formed and whether the formed runoff can be collected based on the instantaneous flow rate of runoff, thereby ensuring that runoff rainwater is collected as soon as runoff is formed at the initial stage of rainfall. Compared with the related art in which samplers are required to manually collect runoff rainwater, this system saves manpower and material resources, improves the real-time nature of runoff sampling, ensures that runoff samples are samples when runoff is formed at the initial stage of rainfall, and improves the accuracy of water quality monitoring of subsequent runoff samples. After the control module 102 of the embodiment of the present invention generates a runoff collection signal according to the runoff formation information, it controls the initial rainfall runoff collection module 103 to perform runoff sampling on the target sampling area according to the runoff collection signal including one or more of the start sampling instruction, the stop sampling instruction and the collection time interval. Therefore, the initial rainfall runoff collection module can sample the runoff hourly according to the collection time interval, thereby improving the flexibility of runoff sampling, so that in the process of water quality monitoring of the runoff samples, the water quality changes in the runoff samples can be dynamically studied, which is convenient for further regular research on pollution load based on the water quality.

[0050] In this embodiment, a runoff sampling system is provided. Figure 2 is a schematic diagram of the structure of another runoff sampling system according to an embodiment of the present invention. Figure 2 As shown, the process includes the following structure:

[0051] The runoff monitoring module 201 is used to monitor the surface runoff in the target sampling area to generate runoff formation information, and to send the runoff formation information to the control module 202; wherein the runoff formation information includes the instantaneous flow of the runoff.

For details, please refer to Figure 1 The control module 102 of the illustrated embodiment will not be described in detail herein.

[0053] The initial rainfall runoff collection module 203 is used to perform runoff sampling in the target sampling area according to the runoff collection signal; wherein the runoff collection signal includes one or more of a start sampling instruction, a stop sampling instruction, and a collection time interval. Figure 1The initial rainfall runoff collection module 103 of the illustrated embodiment will not be described in detail here.

[0054] In some optional embodiments, the runoff collection system also includes: a data processing module 204, which is used to generate an interval time signal based on the received monitoring plan information, and to send the interval time signal to the control module 202; wherein the data processing module 204 is communicatively connected to the control module 202.

[0055] Among them, the monitoring plan information represents the pre-set time plan information for collecting runoff in the target sampling area. The monitoring plan information includes the interval time. For example, the monitoring plan information includes collecting once every 6 minutes. The data processing module 204 is used to generate an interval time signal of 6 minutes based on the monitoring plan information.

[0056] Exemplarily, the data processing module 204 is connected to the control module 202 via wireless communication.

[0057] In addition to obtaining the collection time interval according to the runoff collection signal, the data processing module 204 of the embodiment of the present invention can also customize the interval time signal according to the monitoring plan information to meet the collection requirements, improve the runoff collection efficiency, and optimize the runoff collection process.

[0058] In some optional embodiments, the runoff collection system also includes: a rainfall monitoring module 205, which is used to monitor the rainfall in the target sampling area, generate rainfall monitoring information, and send the rainfall monitoring information to the data processing module 204; wherein the rainfall monitoring module 205 is communicatively connected to the data processing module 204; a runoff monitoring module 201, which is used to send the runoff formation information to the data processing module 204; wherein the runoff monitoring module 201 is communicatively connected to the data processing module 204; the data processing module 204, which is used to store the rainfall monitoring information and the runoff formation information, and send the rainfall monitoring information and the runoff formation information to the control module 202; wherein the data processing module 204 is communicatively connected to the control module 202.

[0059] The rainfall monitoring module 205 includes a rainfall sensor for monitoring rainfall intensity and recording time hour by hour. The rainfall monitoring information includes rainfall intensity and time.

[0060] The rainfall monitoring module 205 of the embodiment of the present invention is used to monitor the rainfall in the target sampling area and generate rainfall monitoring information. The runoff monitoring module 201 is used to send the runoff formation information to the data processing module 204. The data processing module 204 is used to store the rainfall monitoring information and the runoff formation information, which can be used to study the spatial variation law of the pollution load of the surface runoff on the slope in the initial rainfall period, prevent data loss, and call the stored data at any time. The data processing module 204 of the present invention is used to send the rainfall monitoring information and the runoff formation information to the control module 202, so that the control module 202 can control the initial rainfall runoff collection module 203 to sample the runoff according to the rainfall monitoring information and the runoff formation information.

[0061] In some optional embodiments, the runoff collection system also includes: a runoff collection module 206, which is used to collect runoff according to runoff formation information; a runoff diversion module 207, which is used to introduce the runoff collected by the runoff collection module 206 into the initial rainfall runoff collection module 203 according to the runoff collection signal sent by the control module; wherein the runoff diversion module 207 is communicatively connected to the control module 202, and the runoff diversion module 207 is physically connected to the runoff collection module 206 and the initial rainfall runoff collection module 203, respectively.

[0062] Among them, the rainfall monitoring module 205 and the runoff monitoring module 201 are arranged on the runoff collection module 206. The runoff collection module 206 is used to receive the runoff formation information sent by the runoff monitoring module 201, and to preliminarily collect the runoff according to the runoff formation information. Exemplarily, the runoff collection module 206 can be a 1m*0.5m mini runoff cell arranged on a natural slope. The runoff diversion module 207 is provided with a switch and a pipeline. When the runoff collection signal sent by the control module 202 is received, the switch is turned on, and the runoff collected by the runoff collection module 206 is introduced into the initial rainfall runoff collection module 203 through the pipeline.

[0063] Exemplarily, the runoff collection module 206 may be a mini runoff cell module, the runoff diversion module 207 is connected to the control module 202 via wireless communication, and the runoff diversion module 207 is respectively connected to the runoff collection module 206 and the initial rainfall runoff collection module 203 via pipelines.

[0065] The water volume information indicates the total water volume information of the runoff collected by the initial rainfall runoff collection module 203. A water volume sensor is provided in the water volume monitoring module 208. When the maximum rainfall intensity of the runoff sampling system is exceeded, the initial rainfall runoff collection module 203 may have a container overflow problem. Therefore, when the initial rainfall runoff collection module 203 has a container overflow, the total water volume of the runoff in the water volume information exceeds the maximum collection capacity of the initial rainfall runoff collection module 203. The water volume monitoring module 208 is used to send the water volume information to the control module 202, so that the control module 202 controls the closing of the initial rainfall runoff collection module 203 according to the water volume information. When the total water volume of the runoff in the water volume information does not exceed the maximum collection capacity of the initial rainfall runoff collection module 203, the water volume monitoring module 208 is used to send the water volume information to the control module 202, so that the control module 202 controls the opening of the initial rainfall runoff collection module 203 according to the water volume information.

[0066] The water volume monitoring module 208 of the embodiment of the present invention is used to monitor the water volume information of the initial rainfall runoff collection module 203 in real time, so that the control module 202 can control the start and stop of the initial rainfall runoff collection module 203 according to the water volume information, thereby preventing the situation where the water in the initial rainfall runoff collection module 203 is already full but is still being collected, thereby saving resources and improving the efficiency of runoff collection.

[0067] In this embodiment, a runoff sampling system is provided. Figure 3 is a schematic diagram of the structure of another runoff sampling system according to an embodiment of the present invention. Figure 3 As shown, the system includes the following structure:

[0068] The runoff sampling system of the embodiment of the present invention is composed of a rainfall monitoring module 301, a runoff monitoring module 302, a data information storage and processing module 303, a control module 304, a mini runoff cell module 305, a runoff drainage system module 306, a collector water volume sensor 307, and an initial rainfall runoff collection module 308. Among them, the rainfall monitoring module 301 and the runoff monitoring module 302 are arranged on the mini runoff cell module 305, the collector water volume sensor 307 is arranged on the initial rainfall runoff collection module 308, the mini runoff cell module 305 and the initial rainfall runoff collection module 308 are connected in series through the runoff drainage system module 306, and the data information storage and processing module 303 and the control module 304 are arranged on the same module.

[0069] When rainfall starts, the sensor in the rainfall monitoring module 301 detects the rainfall signal and automatically transmits the signal to the data information storage and processing module 303 to record the time when rainfall starts and the rainfall intensity hour by hour.

[0070] When runoff is formed in the mini runoff cell module 305 , the runoff monitoring module 302 (disposed at the end of the mini runoff cell module 305 ) senses the runoff formation signal and transmits the start time of runoff formation and the runoff amount data to the data information storage and processing module 303 .

[0071] After receiving the runoff formation signal from the mini runoff cell module 305 , the data information storage and processing module 303 transmits the runoff formation signal to the control module 304 (the control module 304 is connected to the runoff drainage system module 306 ).

[0072] The control module 304 sends a runoff formation signal to start the runoff drainage system module 306 (connected to the initial rainfall runoff collection module 308 ) to drain the runoff into the sampling collection container in the initial rainfall runoff collection module 308 .

[0073] In some optional embodiments, the transmitted runoff formation signal includes starting collection, collecting at intervals of 5 minutes, and stopping collection, that is, automatic timed sampling at intervals of 5 minutes is completed within 30 minutes after the initial rainfall runoff collection module 308 receives the surface runoff signal, and the corresponding rainfall intensity, runoff volume and time are recorded.

[0074] In some optional implementations, the initial rainfall runoff collection module 308 includes 6 collection containers with a volume of 1 L and volume scales, and each collection container automatically starts collecting and switching at a time interval of every 5 minutes based on the received signal.

[0075] Among them, the runoff sampling system of the embodiment of the present invention is suitable for rainfall intensities less than or equal to 16 mm (heavy rain), that is, the maximum rainfall that can be collected in the mini runoff cell module within one hour is 8L (16 mm * 0.5 square meters), that is, assuming that the rainfall reaches a rainfall intensity of 16 mm from the beginning and continues to maintain this rainfall intensity, and assuming that all runoff is formed without infiltration, then within the first 30 minutes of rainfall, the runoff in the mini runoff cell module is collected every 5 minutes, and the maximum runoff volume is about 0.67 liters, so the single volume of the runoff sampling container in the initial rainfall runoff collection module is 1 liter.

[0076] In this embodiment, a runoff sampling method is provided, which can be used in the above-mentioned runoff sampling system. Figure 4 is a flow chart of a runoff sampling method according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:
