Description

Technical Field

[0001] The present invention relates to the field of waterlogging early warning technology, and in particular to a multi-dimensional safety monitoring and early warning system and a control cabinet. Background Art

[0002] Urban waterlogging refers to the phenomenon that waterlogging disasters occur in cities due to heavy or continuous rainfall that exceeds the city's drainage capacity. The objective cause of urban waterlogging is the high intensity of rainfall and concentrated range. Waterlogging may form in places where rainfall is particularly rapid, and it may also form in places where the rainfall intensity is relatively large and the duration is relatively long. Drainage stations are used to discharge the accumulated water collected in sewers or canals to nearby water systems through drainage stations on rainy days or after rain, thereby improving drainage capacity and alleviating the formation of floods. Drainage stations usually include a water level pool and several water pumps. When the water level exceeds a certain limit, water pumps are used to extract rainwater for discharge.

[0003] On the basis of basin (regional) flood control planning, town master planning and urban flood control planning, attention should be paid to the coordinated management of flood, waterlogging and tidal disasters, and the coordinated management of different regions in the same basin, and full consideration should be given to the drainage and disaster prevention capabilities of towns along the basin, so as to determine the reasonable design of flood peak flow, period flood volume and flood process line, and provide boundary conditions for drainage and waterlogging prevention planning for towns through which floods flow. However, in actual applications, the pump groups in the same area are controlled independently of each other, resulting in a sudden increase in the drainage pressure of the water system when precipitation occurs over a large area, which cannot be coordinated, resulting in waterlogging in some areas. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a multi-dimensional safety monitoring and early warning system and a control cabinet for coordinating the work of pump groups in the area and reducing waterlogging.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A multi-dimensional security monitoring and early warning system, including

[0007] A pressure acquisition module, wherein the pressure acquisition module acquires the valve core pressure,

[0008] A water level acquisition module, wherein the water level acquisition module acquires the water level depth to be defined as water level depth information,

[0009] An operation status monitoring module, wherein the operation status monitoring module obtains operation data of the water pump, wherein the operation data includes operation current data and operation voltage data,

[0010] An information processing module, wherein the information processing module obtains the water level depth information and the valve core pressure data to generate a conventional control signal to control the working state of the pump group;

[0011] An early warning module communicates with the information processing modules of each pump group and determines whether the preset early warning conditions are met. If the preset early warning conditions are met, an early warning control signal is generated to the signal processing module to perform emergency control on each pump group. The priority of the early warning control signal is higher than the conventional control signal.

[0012] Furthermore, the information processing module is configured with a conventional control strategy, which includes obtaining current water level depth information, depth change rate and current drainage volume, and calculating the depth threshold based on the current water level depth information, depth change rate and current drainage volume. If the current water level depth information exceeds the depth threshold, the corresponding pump group is defined as the pump group to be operated and the drainage volume of the pump group to be operated is increased. If the current water level depth information does not exceed the depth threshold, the drainage volume of the pump group to be operated is maintained and the drainage volume of the operating pump group is defined as the target drainage volume. If the current water level depth information is lower than the preset water level lower limit threshold, the operation of the pump group to be operated is stopped.

[0013] Furthermore, the conventional control strategy is configured with an operation allocation sub-strategy, and the operation allocation sub-strategy includes

[0014] Collect the valve core pressure of each water pump in the pump group to be operated and the operating data of each water pump,

[0015] Re-allocate the number of operating pumps based on valve core pressure, operating data and target drainage volume.

[0016] The opening of the water pump is adjusted based on the valve core pressure. The greater the valve core pressure, the greater the distribution opening of the water pump.

[0017] The corresponding pump operation is controlled based on the number of pumps and the allocated opening.

[0018] Furthermore, the conventional control strategy is configured with an operation redistribution sub-strategy, and the operation redistribution sub-strategy includes

[0019] The running time, running times and running data of the water pump are obtained to calculate the estimated life value of each water pump, wherein the estimated life value is negatively correlated with the running time, running times and the change in running data.

[0020] Obtain multiple groups of water pump operation combinations, and calculate the life estimation variance of the pump groups in the pump station under different water pump operation combination modes, where the life estimation variance is the variance between the life estimation values ​​of each water pump.

[0021] The pump operation combination with the smallest life estimation variance is taken as the actual allocation operation combination.

[0022] Furthermore, the preset early warning condition is that the current water level depth information of several pumping stations that meet the adjacent relationship exceeds the depth threshold, and the number exceeds the preset pumping station number threshold. If the early warning condition is met, the emergency control strategy is executed, and the emergency control strategy includes

[0023] Obtain water level information, depth change rate, precipitation forecast, geographical location distribution, historical drainage data and pump group operation status of each pump station.

[0024] Calculate the flood risk factor of each pumping station to reallocate drainage priorities,

[0025] Allocate the initial drainage ratio of the pumping stations based on the drainage priority order.

[0026] Furthermore, the early warning module is configured with a drainage effect verification strategy, which obtains the expected drainage effect of each pump station based on the initial drainage ratio. When the actual drainage effect is lower than the expected drainage effect, the pump efficacy verification is performed, including increasing the operating current data and operating voltage data of each pump in turn, and judging the change in the pumping volume of the pump. If the pumping volume change of one of the pumps is less than the expected change, a pump fault signal is generated and the operation of the pump is stopped, and the operating power of other pumps in the pump station is increased. If the pumping volume change of each pump meets the expected change, the pump station operation is reallocated, and the pump station drainage ratio is reallocated until the actual drainage effect meets the expected drainage effect. If the actual drainage effect of the pump station cannot be adjusted to meet the expected drainage effect, the actual drainage effect of the pump station with the highest drainage priority is used as the operation control target and a flood warning is output.

[0027] Furthermore, if the drainage volume of one of the pumping stations is increased or decreased, and the water level data of other pumping stations change accordingly, it is determined that there is a drainage correlation, and the drainage correlation coefficient between any two pumping stations in the same area is calculated separately, and the initial drainage ratio is readjusted based on the drainage correlation coefficient.

[0028] Furthermore, the multi-dimensional safety monitoring and early warning system is configured with an operation verification module, which verifies the actual operating status of each water pump in the pumping station according to the conventional control signal or the early warning control signal. If it is detected that the actual operating status of the corresponding water pump deviates from the expected operating status, a water pump shutdown signal is generated to stop the operation of the water pump.

[0029] A multi-dimensional safety monitoring and early warning control cabinet is applied to any of the multi-dimensional safety monitoring and early warning systems described above, comprising a cabinet body, in which a PLC controller is arranged.

[0030] Beneficial effects of the present invention:

[0031] 1. The multi-dimensional safety monitoring and early warning system of the present invention realizes all-round and real-time safety monitoring of the pump station through the collaborative work of multiple modules, and can timely obtain key information such as water level, pressure, and pump operation data, and accurately control based on this information, greatly improving the drainage efficiency and effectively preventing the occurrence of flood disasters;

[0032] 2. By dividing the conventional control strategy into emergency control strategy, when it is judged that there is no flood risk, the conventional control strategy is operated; when it is judged that the water level changes of multiple pumping stations in the area are beyond expectations, it is considered that there is a flood risk, and the two control strategies are used for regulation, and the regulation effect is good; the operation allocation sub-strategy and operation redistribution sub-strategy in the conventional control strategy can reasonably allocate the operation tasks of the water pump, extend the service life of the water pump, reduce maintenance costs, and improve the overall operation efficiency of the system; the design of the early warning module and the corresponding emergency regulation strategy and drainage effect verification strategy enable the system to respond quickly in the face of emergency floods and reasonably allocate drainage resources. By calculating the drainage correlation coefficient and adjusting the initial drainage ratio, the collaborative working ability between the pumping stations is enhanced, and the drainage effect of the entire area is optimized.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0042] like Figures 1 to 3 As shown, a multi-dimensional security monitoring and early warning system of this embodiment includes

[0043] A pressure acquisition module, wherein the pressure acquisition module acquires the valve core pressure,

[0044] A water level acquisition module, wherein the water level acquisition module acquires the water level depth to be defined as water level depth information,

[0045] An operation status monitoring module, wherein the operation status monitoring module obtains operation data of the water pump, wherein the operation data includes operation current data and operation voltage data,

[0046] An information processing module, wherein the information processing module obtains the water level depth information and the valve core pressure data to generate a conventional control signal to control the working state of the pump group;

[0047] An early warning module communicates with the information processing modules of each pump group and determines whether the preset early warning conditions are met. If the preset early warning conditions are met, an early warning control signal is generated to the signal processing module to perform emergency control on each pump group. The priority of the early warning control signal is higher than the conventional control signal.

[0048] By dividing the control strategies into conventional control strategies and emergency control strategies, when it is judged that there is no flood risk, the conventional control strategy is implemented; when it is judged that the water level changes of multiple pumping stations in the area are beyond expectations, it is considered that there is a flood risk, and the two control strategies are used for regulation, with good control effects.

[0049] Furthermore, the information processing module is configured with a conventional control strategy, which includes obtaining current water level depth information, depth change rate and current drainage volume, and calculating the depth threshold according to the current water level depth information, depth change rate and current drainage volume. The calculation formula of the depth threshold is as follows:

[0050]

[0051] Where D represents the depth threshold, D0 represents the current water level depth, represents the depth change rate, Q represents the current drainage volume, The weight parameter representing the depth change rate, Represents the weight parameter of the current drainage volume.

[0052] If the current water level depth information exceeds the depth threshold, the corresponding pump group is defined as the pump group to be operated and the drainage volume of the pump group to be operated is increased. If the current water level depth information does not exceed the depth threshold, the drainage volume of the pump group to be operated is maintained and the drainage volume of the operating pump group is defined as the target drainage volume. If the current water level depth information is lower than the preset water level lower limit threshold, the operation of the pump group to be operated is stopped.

[0053] Conventional control strategies include several key steps. First, obtain the current water level depth information, depth change rate, and current drainage volume. The depth change rate reflects the speed at which the water level rises or falls, which is crucial for judging the development trend of flood disasters; the current drainage volume is used to understand the current working performance of the pump group.

[0054] Then, the depth threshold is calculated based on these data. If the current water level depth information exceeds the depth threshold, it means that the water level has reached or is close to a dangerous level. At this time, the corresponding pump group is defined as a pump group to be operated, and its drainage capacity is increased to speed up drainage and lower the water level. For example, when the water level in a certain area of ​​the city rises rapidly and exceeds the depth threshold, the system will automatically increase the drainage capacity of the pump group of the pump station near the area.

[0055] If the current water level depth information does not exceed the depth threshold, the drainage volume of the pump group to be operated is maintained, and the drainage volume of the operating pump group is defined as the target drainage volume. This is to reasonably distribute the workload of the pump group and improve energy efficiency while ensuring the stability of the water level.

[0056] If the current water level depth information is lower than the preset water level lower limit threshold, it indicates that the accumulated water has been basically drained. At this time, the operation of the pump group to be operated is stopped to avoid energy waste and unnecessary loss of equipment.

[0057] Furthermore, the conventional control strategy is configured with an operation allocation sub-strategy, and the operation allocation sub-strategy includes

[0058] Collect the valve core pressure of each water pump in the pump group to be operated and the operating data of each water pump,

[0059] Re-allocate the number of operating pumps based on valve core pressure, operating data and target drainage volume.

[0060] The opening of the water pump is adjusted based on the valve core pressure. The greater the valve core pressure, the greater the distribution opening of the water pump.

[0061] The corresponding pump operation is controlled based on the number of pumps and the allocated opening.

[0062] This setting takes into account that the water pump with a large valve core pressure in the same pump group will have a higher pumping efficiency under the same conditions, thereby reducing energy consumption and improving drainage efficiency.

[0063] Furthermore, the conventional control strategy is configured with an operation redistribution sub-strategy, and the operation redistribution sub-strategy includes

[0064] The running time, running times and running data of the water pump are obtained to calculate the estimated life value of each water pump, wherein the estimated life value is negatively correlated with the running time, running times and the change in running data.

[0065] Obtain multiple groups of water pump operation combinations, and calculate the life estimation variance of the pump groups in the pump station under different water pump operation combination modes, where the life estimation variance is the variance between the life estimation values ​​of each water pump.

[0066] The pump operation combination with the smallest life estimation variance is used as the actual allocation operation combination. This can extend the service life of the entire pump station pump group, reduce maintenance costs, and improve system reliability.

[0067] Furthermore, the preset early warning condition is that the current water level depth information of several pumping stations that meet the adjacent relationship exceeds the depth threshold, and the number exceeds the preset pumping station number threshold. If the early warning condition is met, the emergency control strategy is executed, and the emergency control strategy includes

[0068] Obtain water level information, depth change rate, precipitation forecast, geographical location distribution, historical drainage data and pump group operation status of each pump station.

[0069] Calculate the flood risk factor of each pumping station to reallocate drainage priorities,

[0070] Allocate the initial drainage ratio of the pumping stations based on the drainage priority order.

[0071] Furthermore, the early warning module is configured with a drainage effect verification strategy, which obtains the expected drainage effect of each pump station based on the initial drainage ratio. When the actual drainage effect is lower than the expected drainage effect, the pump efficacy verification is performed, including increasing the operating current data and operating voltage data of each pump in turn, and judging the change in the pumping volume of the pump. If the pumping volume change of one of the pumps is less than the expected change, a pump fault signal is generated and the operation of the pump is stopped, and the operating power of other pumps in the pump station is increased. If the pumping volume change of each pump meets the expected change, the pump station operation is reallocated, and the pump station drainage ratio is reallocated until the actual drainage effect meets the expected drainage effect. If the actual drainage effect of the pump station cannot be adjusted to meet the expected drainage effect, the actual drainage effect of the pump station with the highest drainage priority is used as the operation control target and a flood warning is output to remind relevant departments to take other emergency measures, such as organizing personnel for rescue and evacuating the masses.

[0072] Furthermore, if the drainage volume of one pumping station is increased or decreased, and the water level data of other pumping stations change accordingly, it is determined that there is a drainage correlation, and the drainage correlation coefficient between any two pumping stations in the same area is calculated respectively, and the initial drainage ratio is readjusted based on the drainage correlation coefficient. In this way, the work between the various pumping stations can be coordinated more accurately, the drainage coordination of the entire area can be improved, and the adverse effects on other pumping stations due to the adjustment of the drainage volume of a certain pumping station can be avoided.

[0073] Furthermore, the multi-dimensional safety monitoring and early warning system is configured with an operation verification module, which verifies the actual operating status of each water pump in the pumping station according to the conventional control signal or the early warning control signal. If it is detected that the actual operating status of the corresponding water pump deviates from the expected operating status, a water pump shutdown signal is generated to stop the operation of the water pump.

[0074] See also Figures 4 to 6 A multi-dimensional safety monitoring and early warning control cabinet is applied to the multi-dimensional safety monitoring and early warning system described above, including a cabinet, in which a PLC controller is arranged. As the control core of the system, the PLC controller is responsible for receiving data from each module, processing it according to preset programs and algorithms, and issuing corresponding control signals. It has the advantages of high reliability, flexible programming, and strong anti-interference ability, and can ensure the stable and efficient operation of the entire system. At the same time, the design of the cabinet also fully considers factors such as heat dissipation and protection, providing a good working environment for the PLC controller and other electronic components.

[0075] Each multi-dimensional safety monitoring and early warning control cabinet controls a corresponding pump station. The controller is equipped with a wireless 4G Internet of Things gateway, which is connected to the dispatching center through the public network, that is, specifically connected to the early warning module mentioned above.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
