Description

Technical Field

[0001] The present invention relates to the technical field of fault detection, and in particular to a node fault detection system based on blockchain. Background Art

[0002] With the development of society, people have higher and higher requirements for living environment. They not only need beautiful environment and convenient transportation, but also intelligent and comfortable living environment. Under such background, smart residential areas have become a living style that people are more and more fond of. The planning of smart residential areas should start from reality, coordinate planning and construction, and adopt the construction concept of "humanization, technology, greenness and publicness". First of all, unified planning and design should be carried out, and the architectural style should be strengthened. A building system with beautiful facades and unique characteristics should be built. In terms of road planning, the distance within the community should be shortened as much as possible, and the supporting facilities in each functional area should be reasonably combined to build a complete community water supply, power supply, gas supply and the most advanced communication network system. At the same time, attention should be paid to the protection and utilization of water resources, and renewable energy and energy-saving technologies should be used; At present, when the community is being built, the application of intelligence is limited to the interior of the house, and the basic functions of the community cannot be intelligentized. For example, the intelligent management of sewers makes it impossible for the sewers to receive rainwater in time during heavy rain, causing serious waterlogging in the community. Therefore, it is necessary to design a node fault detection system based on blockchain. Summary of the invention

[0003] The purpose of the present invention is to provide a node fault detection system based on blockchain to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a node fault detection system based on blockchain, comprising a node detection module, a main valve detection module, and a detection module, wherein the node detection module is used to detect the conditions of the branch pipelines inside the community and the conditions of the connection nodes between the branch pipelines; The main valve detection module is used to detect the status of the connection node between the branch pipeline and the main pipeline; The detection module is used to detect the change of water inflow in the community and the expected water inflow.

[0005] According to the above technical solution, the node detection module includes a branch pipeline detection unit, a branch pipeline adjustment unit, a branch pipeline cleaning unit and a branch pipeline node fault detection unit; The branch pipeline detection unit is used to detect the amount of water accumulated in the branch pipeline; The branch pipeline regulating unit is used to regulate the water flow rate in the branch pipeline. The branch pipeline cleaning unit is used to confirm whether the branch pipeline is blocked; The branch pipeline node fault detection unit is used to confirm whether the branch pipeline and the node where the branch pipeline connects with other pipelines are faulty.

[0006] According to the above technical solution, the main valve detection module includes a building valve management unit, a community valve management unit, a ground pipeline valve unit and an underground pipeline valve unit; The building valve management unit is used to detect the pipeline conditions of each building in the community and regulate the drainage volume of each building; The community valve management unit is used to control the drainage and storage volume of the community; The ground pipeline valve unit is used to control the drainage volume of the ground branch pipeline; The underground pipeline valve unit is used to regulate the drainage volume of the underground branch pipeline.

[0007] According to the above technical solution, the detection module includes a weather prediction unit and a rainfall detection unit; The weather prediction unit is connected to a weather forecast information website to receive weather information of the area in the community in real time; The rainfall detection unit is used to estimate the amount of rainwater entering the community on rainy days. At the same time, the rainwater detection unit is connected to the main valve detection module, so that the main valve detection module receives the detection information of the rainwater detection unit in real time to obtain the expected amount of water entering the community on rainy days.

[0008] According to the above technical solution, the steps for regulating the drainage mode in the community are: S1, the detection module receives the weather conditions of the area of ​​the community through the weather prediction unit, and the weather prediction unit divides the weather of the area of ​​the community into rainy weather and non-rainy weather. If the area of ​​the community is rainy weather, the weather prediction unit transmits this information to the main valve detection module, and controls the drainage mode of the community through the main valve detection module. If the area of ​​the community is non-rainy weather, the weather prediction unit does not transmit this information to the main valve detection module; S2: If the main valve detection module receives a signal that the area is in rainy weather, it will control the building valve management unit to increase the drainage volume to avoid water accumulation on the top of the building. S3, after each rainy day, the node detection module detects all pipelines to confirm that the drainage volume of all branch pipelines is normal. If the drainage volume is abnormal, an alarm will be issued, and the abnormal location will be provided, calling the property for maintenance to avoid pipeline leakage and water flow spreading to the ground and garage in the community.

[0009] According to the above technical solution, the detailed process in step S1 is: The detection module includes two functions. The first is to provide weather information for the node detection module and the main valve detection module. The second is to estimate the precipitation data in the community. The detection module sets the precipitation that the community can obtain on rainy days to V, which is divided into 12 levels from V1 to V12. V1 means that the community can obtain the least precipitation on rainy days, and V12 means that the community can obtain the most precipitation on rainy days. The main valve detection module sets the drainage volume of each building to B, which is divided into 11 levels from B1 to B11. B1 means that the drainage volume of each building is the least, and B11 means that the drainage volume of each building is the highest. V1-V11 and B1-B11 are paired one by one. Should, according to the amount of precipitation that the community can get on rainy days, adjust the drainage volume of each building to achieve the effect of no water accumulation in the community buildings. The drainage of the building is the drainage process in which the drainage pipes in the building discharge water into the community main pipeline. By setting an electric control valve between the drainage pipes of each building and the main pipeline, the drainage volume of each building can be controlled. If the drainage volume of each building is continuously maintained at the highest, the water flow in each building will flow into the main pipe at the fastest speed, and the water flow in the main pipe cannot be controlled in time. When the water flow in the main pipe exceeds the limit, each building needs to reduce the amount of water discharged into the main pipe. This process of reducing the drainage volume of each building takes time; The drainage volume of the B1 level can maintain the basic drainage volume of each building and will not cause drainage blockage in the building; The building drainage discharges water into the water tank installed in each building, and then discharges it into the main pipe through the water tank. The electric control valve is installed between the water tank and the main pipe.

[0010] According to the above technical solution, the detailed process in step S2 is: In rainy weather, if the precipitation that the community can obtain on rainy days is V1-V11, the surface drainage and underground drainage will be cut off, and drainage will be carried out in real time. Two main pipes will be set up in the community, one of which is responsible for surface drainage and the other is responsible for underground drainage. In non-rainy weather, the main pipe connected to the underground drainage is used for drainage. The main pipe connected to the underground drainage is located low and can be used for drainage of the entire community. In rainy weather, the main pipe connected to the surface drainage and the main pipe connected to the underground drainage are used for drainage at the same time. The main pipe connected to the underground drainage is only responsible for drainage of the community's underground garage, and the main pipe connected to the surface drainage is only responsible for drainage of the community's ground buildings and equipment.

[0011] According to the above technical solution, underground drainage analysis: If the precipitation that the community can obtain on rainy days is V12, several pumps installed between the underground main pipe and the ground main pipe are turned on, and the underground pipeline valve controls the pump to start pumping the water in the underground main pipe to the ground main pipe to ensure smooth drainage of the underground garage. At the same time, the ground pipeline valve unit opens the electric control valve in the building to the minimum, that is, the V12 level corresponds to the B1 level, that is, when the precipitation in the community is the largest, the drainage of each building is the smallest, leaving enough space for the ground main pipe to drain the underground garage. At this time, the drainage of each building is concentrated in the water tank, and a water level monitor is set in the water tank. The water level monitor monitors the water level in the water tank in real time. When the water level monitor detects that the water level in the water tank is full, the ground pipeline valve unit opens the electric control valve in the building to the B11 level and starts to empty the water tank. Since the water storage speed of the water tank of each building is inconsistent, the water in the water tank can be discharged into the ground main pipe separately with the drainage volume of the B11 level; The main valve detection module records the duration of V12 precipitation that the community can obtain on rainy days, which is recorded as K, one of the time nodes is K1. If the duration of V12 precipitation that the community can obtain on rainy days reaches K1, the main valve detection module opens the main valve set between the two main pipes and the main water tank, so that the two main pipes begin to divert part of the water to the main water tank. Due to the high precipitation, the pipelines in the community are continuously flushed with high flow, so that the water flow quality during this process is relatively high. The main water tank collects the water in this process and can be used as social water after the precipitation ends.

[0012] According to the above technical scheme, a water pressure detector and a water flow detector are set at the connection between the main pipe and the branch pipe. The water pressure detector is used to detect whether the connection between the main pipe and the branch pipe is faulty, and the water flow detector is used to detect whether the connection between the main pipe and the branch pipe is blocked. The water pressure detector and the water flow detector transmit the detection data to the node detection module in real time. The node detection module sets the U1 value. If the water pressure detector detects a value lower than U1, it means that the connection between the main pipe and the branch pipe is faulty. The node detection module immediately locks the fault position and transmits the fault position to the property station, calling the property staff for emergency repairs. The node detection module sets the P1 value. If the water flow detector detects a value lower than U1, it means that the connection between the main pipe and the branch pipe begins to be blocked. The node detection module immediately locks the fault position and transmits the fault position to the property station. The property staff opens the manhole cover closest to the marked position and uses the matching cleaning tools to clean it.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention, by providing a main valve detection module, uses the main pipe connected to the ground drainage and the main pipe connected to the underground drainage for drainage at the same time in rainy weather, the main pipe connected to the underground drainage is only responsible for draining the underground garage of the community, and the main pipe connected to the ground drainage is only responsible for draining the ground buildings and equipment of the community, thereby reducing the burden of the main pipe connected to the underground drainage and avoiding water accumulation in the underground garage; if the precipitation that the community can obtain on rainy days is V12, several water pumps arranged between the underground main pipe and the ground main pipe are turned on, and the underground pipeline valve controls the water pump to start and pump the water in the underground main pipe into the ground main pipe, thereby ensuring smooth drainage of the underground garage.

At the same time, the rainwater detection unit is connected to the main valve detection module, so that the main valve detection module receives the detection information of the rainwater detection unit in real time and learns the expected water inflow on rainy days.

[0020] Steps to control drainage patterns within a plot: S1, the detection module receives the weather conditions of the cell area through the weather prediction unit. The weather prediction unit divides the weather in the cell area into rainy weather and non-rainy weather. If the cell area is rainy weather, the weather prediction unit transmits this information to the main valve detection module, and controls the drainage mode of the cell through the main valve detection module. If the cell area is non-rainy weather, the weather prediction unit does not transmit this information to the main valve detection module; S2: If the main valve detection module receives a signal that the community is in rainy weather, it will control the building valve management unit to increase the drainage volume to avoid water accumulation on the top of the building. S3, after each rainy day, the node detection module detects all pipelines to confirm that the drainage volume of all branch pipelines is normal. If the drainage volume is abnormal, an alarm will be issued, and the abnormal location will be provided, calling the property for maintenance to avoid pipeline leakage and water flow spreading to the ground and garage in the community.

[0021] Detailed process in step S1: The detection module includes two functions. The first is to provide weather information for the node detection module and the main valve detection module. The second is to estimate the precipitation data in the community. The detection module sets the precipitation that the community can obtain on rainy days to V, which is divided into 12 levels from V1 to V12. V1 indicates that the community can obtain the least precipitation on rainy days, and V12 indicates that the community can obtain the most precipitation on rainy days. The main valve detection module sets the drainage volume of each building to B, which is divided into 11 levels from B1 to B11. B1 indicates that the drainage volume of each building is the least, and B11 indicates that the drainage volume of each building is the highest. V1-V11 corresponds to B1-B11 one by one. The drainage volume of each building is adjusted according to the precipitation that the community can obtain on rainy days. Drainage volume, to achieve the effect of no water accumulation in the community buildings. The drainage of the buildings is the drainage process of discharging water from the drainage pipes in the buildings to the community main pipes. By setting an electrically controlled valve between the drainage pipes of each building and the main pipe, the drainage volume of each building can be controlled. If the drainage volume of each building is continuously maintained at the highest, the water flow in each building will flow into the main pipe at the fastest speed, and the water flow in the main pipe cannot be controlled in time. When the water flow in the main pipe exceeds the limit, each building needs to reduce the amount of water discharged into the main pipe. This process of reducing the drainage volume of each building takes time. In this application, the drainage volume of each building is controlled according to the amount of rainwater, which can ensure that each building is drained with the minimum drainage volume in rainless weather; The drainage volume of the B1 level can maintain the basic drainage volume of each building and will not cause drainage blockage in the building; The building drainage discharges water into the water tank installed in each building, and then discharges it into the main pipe through the water tank. The electric control valve is installed between the water tank and the main pipe.

[0022] Detailed process in step S2: In rainy weather, if the precipitation that the community can obtain on rainy days is V1-V11, the surface drainage and underground drainage will be cut off, and drainage will be carried out in real time. Two main pipes will be set up in the community, one of which is responsible for surface drainage and the other is responsible for underground drainage. In non-rainy weather, the main pipe connected to the underground drainage is used for drainage. The main pipe connected to the underground drainage is located low and can be used for drainage of the entire community. In rainy weather, the main pipe connected to the surface drainage and the main pipe connected to the underground drainage are used for drainage at the same time. The main pipe connected to the underground drainage is only responsible for drainage of the community's underground garage, and the main pipe connected to the surface drainage is only responsible for drainage of the community's ground buildings and equipment, thereby reducing the burden on the main pipe connected to the underground drainage and avoiding water accumulation in the underground garage.

[0023] Subsurface drainage analysis: If the precipitation that the community can obtain on a rainy day is V12, several pumps installed between the underground main pipe and the ground main pipe will be turned on, and the underground pipeline valve will control the pump to start pumping the water in the underground main pipe to the ground main pipe to ensure smooth drainage of the underground garage. At the same time, the ground pipeline valve unit will open the electric control valve in the building to the minimum, that is, the V12 level corresponds to the B1 level, that is, when the precipitation in the community is the largest, the drainage of each building is the smallest, leaving enough space for the ground main pipe for the underground garage. Drainage, at this time, the drainage of each building is concentrated in the water tank. A water level monitor is set in the water tank. The water level monitor monitors the water level in the water tank in real time. When the water level monitor detects that the water level in the water tank is full, the ground pipeline valve unit opens the electric control valve in the building to the B11 level and starts to empty the water tank. Since the water storage speed of the water tank of each building is inconsistent, the water in the water tank can be discharged into the ground main pipe separately with the drainage volume of the B11 level to avoid excessive water storage load on the ground main pipe; The main valve detection module records the duration of V12 precipitation that the community can obtain on rainy days, which is recorded as K, one of the time nodes is K1. If the duration of V12 precipitation that the community can obtain on rainy days reaches K1, the main valve detection module opens the main valve set between the two main pipes and the main water tank, so that the two main pipes begin to divert part of the water to the main water tank. Due to the high precipitation, the pipelines in the community are continuously flushed with high flow, so that the water flow quality during this process is relatively high. The main water tank collects the water in this process, which can be used as social water after the precipitation ends, such as watering community greening, etc., while diverting the main pipes, providing another way to use this water flow, saving water.

[0024] A water pressure detector and a water flow detector are set at the connection between the main pipe and the branch pipe. The water pressure detector is used to detect whether the connection between the main pipe and the branch pipe is faulty, and the water flow detector is used to detect whether the connection between the main pipe and the branch pipe is blocked. The water pressure detector and the water flow detector transmit the detection data to the node detection module in real time. The node detection module sets the U1 value. If the water pressure detector detects a value lower than U1, it means that the connection between the main pipe and the branch pipe is faulty. The node detection module immediately locks the fault location and transmits the fault location to the property station, calling the property staff for emergency repair. The node detection module sets the P1 value. If the water flow detector detects a value lower than U1, it means that the connection between the main pipe and the branch pipe begins to be blocked. The node detection module immediately locks the fault location and transmits the fault location to the property station, and the property staff opens the pipe manhole cover closest to the marked position and uses the matching cleaning tools to clean it. This detection method can save the preliminary detection process, and there is no need to ask maintenance personnel to spend money to detect faults or blocked areas, and then spend money to repair them. The method of detecting faulty nodes in the present application is quick to detect, convenient to maintain, and low in cost.
