[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] The present invention provides a method and system for emergency dispatching of a pump station group.

[0050] As attached Figure 1 As shown, in a first embodiment of a pump station group emergency dispatch method proposed by the present invention, the pump station group emergency dispatch method is applied to a pump station group emergency dispatch system; the system includes a pump station terminal and a cloud server; the pump station terminal corresponds to the pump station one-to-one, and the pump station terminal is set at the corresponding pump station; the pump station terminal includes a monitoring controller, a water level sensor and a water pump controller; the water pump controller is used to control the start and stop of each water pump in the pump station; the monitoring controller and the water level sensor are communicatively connected; the monitoring controller and the water pump controller are both communicatively connected to the cloud server; this embodiment includes the following steps:

[0051] Step S110: the monitoring controller obtains the current water level of the outer river and the rising speed of the outer river water level at the pumping station every first preset time period (for example, 3 minutes) through the water level sensor.

[0052] Step S120: The monitoring controller sends the current water level of the outer river and the rising speed of the outer river water level to the cloud server.

[0053] Step S130: The cloud server determines whether the emergency dispatch conditions are met based on the current water level of the outer river and the rising speed of the outer river water level.

[0054] Specifically, if the current water level of the outer river is high, or the water level of the outer river rises at a high speed, it means that the flood situation of the outer river is relatively urgent. At this time, the conditions for emergency dispatch are met, that is, unified emergency dispatch of each pumping station is carried out to respond quickly to the flood situation and prevent flooding due to delayed response.

[0055] If so, execute step S140: the cloud server generates an emergency dispatch instruction corresponding to the pump station based on the current water level of the outer river and the rising speed of the water level of the outer river, and sends the emergency dispatch instruction to the pump station controller of the corresponding pump station.

[0056] Step S150: The pump station controller controls the start and stop of each water pump in the pump station based on the received emergency dispatch instruction.

[0057] The pump station group emergency dispatch method proposed in the present invention can timely and quickly carry out unified dispatch of multiple pump stations to cope with complex and rapidly changing water conditions; specifically, first, the current water level of the outer river and the rising speed of the outer river water level obtained by the monitoring controller and the water level sensor are used to judge in real time whether the emergency dispatch conditions are met. If the emergency dispatch conditions are met, the cloud server will generate corresponding emergency dispatch instructions based on the current water level of the outer river and the rising speed of the outer river water level of each pump station, and send the emergency dispatch instructions to the pump station controller of the corresponding pump station. Then, the pump station controller controls the start and stop of each water pump in the pump station based on the received emergency dispatch instructions, thereby realizing emergency linkage dispatch of multiple pump stations in the area, which can respond to flood conditions more efficiently and promptly.

[0058] In a second embodiment of a method for emergency dispatching a group of pump stations proposed by the present invention, based on the first embodiment, step S110 includes the following steps:

[0059] Step S210: The water level sensor obtains the current water level of the outer river and marks it as the first water level.

[0060] Step S220: The water level sensor obtains the outer river water level again after a second preset time (for example, 1 minute) after obtaining the first water level, and marks it as the second water level, wherein the second preset time is shorter than the first preset time.

[0061] Step S230: The monitoring controller obtains the rising speed of the outer river water level based on the first water level, the second water level and the second preset time.

[0062] Step S240: the monitoring controller uses the second water level as the current water level of the outer river.

[0063] This embodiment provides a specific solution for obtaining the current water level of the external river at the pumping station and the rising speed of the external river water level based on the water level sensor.

[0064] In a third embodiment of a pump station group emergency dispatch method proposed by the present invention, based on the second embodiment, the monitoring controller obtains a calculation formula for the rising speed of the outer river water level based on the first water level, the second water level, and the second preset time:

[0065]

[0066] Where S w is the rising speed of the outer river water level; W1 is the first water level, in meters; W2 is the second water level, in meters; T2 is the second preset time length, in seconds.

[0067] This embodiment provides a specific formula for calculating the rising speed of the outer river water level.

[0068] In a fourth embodiment of a method for emergency dispatching a pump station group proposed by the present invention, based on the first embodiment, step S130 includes the following steps:

[0069] Step S410: The cloud server determines whether any one of the first condition, the second condition or the third condition is met, wherein the first condition is: the current water level of the outer river is greater than the first warning water level (for example, 15 meters); the second condition is: the rising speed of the outer river water level is greater than the first preset speed (for example, 0.3 meters / hour); the third condition is: the current water level of the outer river is greater than the second warning water level (for example, 10 meters), and the rising speed of the outer river water level is greater than the second preset speed (for example, 0.1 meters / hour), the second warning water level is lower than the first warning water level, and the second preset speed is lower than the first preset speed.

[0070] Specifically, the first warning water level, the second warning water level, the first preset speed and the second preset speed are all determined artificially; the first warning water level corresponds to the water level when an emergency and serious flood occurs, the second warning water level corresponds to the water level when a relatively emergency flood occurs, the first preset speed corresponds to the rising speed when an emergency and serious flood occurs, and the second preset speed corresponds to the rising speed when a relatively emergency flood occurs.

[0071] If so, execute step S420: determine whether the emergency dispatch conditions are met.

[0072] If not, execute step S430: determine whether the emergency dispatch condition is not met.

[0073] This embodiment provides a specific solution for determining whether the emergency dispatch conditions are currently met.

[0074] In a fifth embodiment of a method for emergency dispatching a group of pump stations proposed by the present invention, based on the fourth embodiment, step S140 includes the following steps:

[0075] Step S510: When the current water level of the outer river is lower than the second warning water level, the cloud server generates a first emergency dispatch instruction, wherein the first emergency dispatch instruction is to turn on a first preset proportion (for example, 50%) of the water pumps in the pump station.

[0076] Step S520: When the current water level of the outer river is greater than the second warning water level and lower than the first warning water level, the cloud server generates a second emergency dispatch instruction, wherein the second emergency dispatch instruction is to turn on a second preset proportion of water pumps in the pumping station, and the second preset proportion (for example, 70%) is greater than the first preset proportion.

[0077] Step S530: When the current water level of the outer river is greater than the first warning water level, the cloud server generates a third emergency dispatch instruction, wherein the third emergency dispatch instruction is to turn on all water pumps in the pump station.

[0078] This embodiment provides a specific emergency dispatching solution, which is to start different numbers of water pumps according to different water levels during flood conditions.

[0079] In a sixth embodiment of a method for emergency dispatching a group of pump stations proposed by the present invention, based on the first embodiment, step S140 further includes the following steps:

[0080] Step S610: The cloud server determines the pumping station corresponding to the flood peak position based on the external river water level corresponding to each pumping station and the external river water level rising speed, and marks it as the first target pumping station.

[0081] Step S620: The cloud server marks the pumping station upstream of the first target pumping station as the second target pumping station, and marks the pumping station downstream of the first target pumping station as the third target pumping station.

[0082] Step S630: The cloud server generates a fourth emergency dispatch instruction corresponding to the first target pump station, wherein the fourth emergency dispatch instruction is to turn on all water pumps in the pump station.

[0084] Step S650: The cloud server generates a sixth emergency dispatch instruction corresponding to the third target pump station, wherein the sixth emergency dispatch instruction is to turn on a fourth preset proportion (for example, 30%) of water pumps in the pump station, and turn off the remaining water pumps, and the sum of the third preset proportion and the fourth preset proportion is a preset value (for example, 1).

[0085] This embodiment provides a specific emergency dispatching solution, which is to start different numbers of water pumps in the upstream and downstream of the flood peak during flood conditions.

[0086] In a seventh embodiment of a method for emergency dispatching a group of pump stations proposed by the present invention, based on the fourth embodiment, step S140 further includes the following steps:

[0087] Step S710: The cloud server obtains the peak value of the current water level of the outer river within the first preset time period (eg, 48 hours) in the past.

[0088] Step S720: The cloud server determines whether the current water level of the outer river is lower than the peak value.

[0089] If so, execute step S730: the cloud server generates a seventh emergency dispatch instruction, wherein the seventh emergency dispatch instruction is to shut down one water pump in the pumping station whenever the current water level of the outer river drops to a preset water level value (for example, 50 cm), and the order of shutting down the water pumps is sorted in descending order according to the continuous operation time of the water pumps.

[0090] Specifically, if the current water level of the outer river is lower than the peak level in the past 48 hours, it means that the peak of the flood has passed. At this time, the water pumps in the pumping station should be stopped to allow them to rest.
