Referring to fig. 1, a structure of an intelligent control system and a control method for drainage of a construction project according to an embodiment of the present application is shown.
As shown in fig. 1, the intelligent control system for drainage of construction engineering is applied to a drainage construction structure and equipment of construction engineering, and the drainage construction structure comprises a drainage ditch 1, a water collecting well 2 and a sewage treatment tank 4.
Wherein, this escape canal 1 locates engineering foundation ditch inboard escape canal 1 all around, and this sump pit 2 is through communicating with escape canal 1 for the rivers of escape canal 1 flow to sump pit 2, in order to play water storage capacity. The sewage treatment tank 4 can comprise a plurality of tanks with different treatment functions, such as a flocculation tank, a sedimentation tank, a valveless filter and the like. A sewage pump 3 is arranged between the water collecting well 2 and the sewage treatment tank 4 and is used for pumping the sewage in the water collecting well 2 to the sewage treatment tank 4.
Referring to fig. 2, another structure of the intelligent control system for drainage of construction engineering according to the embodiment of the present application is shown.
In combination with 2, the control system is provided with a plurality of water level sensors, including:
a first water level sensor 51 provided at a predetermined water level of the drainage ditch 1, the water level sensor being spaced along the drainage ditch 1 for generating a first sensing signal; a second water level sensor 52 disposed at a predetermined water level of the sump 2 for generating a second sensing signal; a third water level sensor 53, which is disposed at a preset water level of the sewage treatment tank 4 and is configured to generate a third sensing signal;
wherein, water level sensor can be through capacitanc water level sensor or floater formula water level sensor, and specific water level sensor kind can be chooseed for use according to the place needs, and this application does not do the injecing to this.
The preset water level may be a critical water level set based on a drainage requirement. For example, a preset water level is set inside the notch near the drainage ditch 1, and when the water level reaches this preset position, it can be suggested that the water level currently in the drainage ditch 1 is at a higher level. For another example, a third water level sensor 53 is disposed near the water level line of the maximum treatment capacity of the wastewater treatment tank 4, and when the water level reaches the preset position, a third sensing signal is triggered to be generated to indicate that the current water level of the wastewater treatment tank 4 has reached the critical point.
The control system further comprises a control module 6, wherein the control module 6 is in communication connection with the first water level sensor 51, the second water level sensor 52, the third water level sensor 53 and the sewage pump 33, and is used for controlling the sewage pump 33 to perform a drainage operation according to the received first sensing signal, the received second sensing signal or the received third sensing signal.
The control of the sewage pump 33 for the draining operation may include turning on/off the sewage pump 33, or changing the draining rate of the sewage pump 33.
In some embodiments, the control system is specifically configured to generate a first pumping rate and a second pumping rate with different values based on the base pumping rate according to the first sensing signal, the second sensing signal or the third sensing signal; wherein the base pumping rate is associated with a current weather condition.
The information of the weather condition can be acquired through a network, or the current weather condition is input by a manager for acquisition, or the current air humidity is sensed based on a humidity sensor, and the air humidity is used as the basis of the weather condition. When the weather condition information reflects the possibility of rainstorm weather, the basic pumping rate of the sewage pump 33 can be increased to cope with the possibility of severe rainstorm weather. When the information of the weather condition reflects that the current weather is better, such as sunny days and the like, the preset basic water pumping rate can be maintained, so that the working loss of the equipment is reduced.
Through the first speed of drawing water and the second speed of drawing water of difference, can be so that sewage pump 33 can be according to the different water level condition of escape canal 1, sump pit 2 and sewage treatment pond 4, according to the demand adjustment drainage efficiency of difference, and then not only ensure that the drainage process is reliable and stable to can also protect the safety of each drainage structure and equipment as far as possible, thereby realize carrying out intelligent control to control system's drainage process.
In one embodiment, the control system further comprises a weather monitoring module. The weather monitoring module is used for obtaining the current weather early warning information through a network. The control system is specifically configured to: adjusting the basic pumping speed of the sewage pump 33 according to the grade of the weather early warning information; when the grade of the weather warning information is high, the basic pumping speed of the sewage pump 33 is increased; when the level of the weather warning information is low, the basic pumping rate of the sewage pump 33 is maintained or reduced.
The weather early warning information can be a heavy rain alarm issued by a local astronomical table. For example, if the weather monitoring module acquires a red rainstorm warning issued by an astronomical phenomena table, it indicates that severe water immersion may occur on a building construction site for several hours in the future, and at the moment, the basic water pumping rate can be greatly increased to prepare for emergency water drainage in advance. Otherwise, if the weather warning information does not receive the information of the rainstorm warning, the basic water pumping rate can be maintained or reduced.
Of course, the weather monitoring module can integrate monitoring components such as a hygrometer, an anemometer or a thermometer and the like to obtain more comprehensive current weather condition information.
Through combining with weather early warning information, can judge the control strategy of sewage pump 33 based on the difference of weather early warning information for sewage pump 33's control mode has pertinence and promptness more, improves the intelligent degree of control.
In some embodiments, the weather monitoring module is specifically configured to:
acquiring weather information within a preset time length in the future, wherein the weather information comprises at least one of rainstorm early warning information, rainfall probability information and rainfall information; the control system is specifically further configured to: determining the expected rainfall in the future preset time according to the weather information; and determining the basic pumping rate according to the expected rainfall.
The weather information in the future preset time period may be weather information of 24 hours, 2 days or a week in the future, and the specific time period may be adjusted according to actual needs, for example, only the weather information in the 24 hours in the future is specified. The rainstorm early warning information can comprise rainstorm early warning information issued by weather issuing organizations such as astronomical benches and the like, such as red rainstorm early warning, orange rainstorm early warning and the like; the rainfall probability information may be information of probability that a weather release mechanism such as an astronomical observatory predicts rainfall within a period of time in the future; the rainfall information may be rainfall probability information in a future period of time, which is issued by a weather issuing organization such as an astronomical tower.
For example, if a red rainstorm warning is received, the corresponding rainfall criteria are: the rainfall will be above 100 mm in 3 hours, or already above 100 mm and the rainfall may continue. The expected rainfall is higher and then the basic pumping rate needs to be adjusted to be higher. Alternatively, if the expected rainfall received 24 hours into the future is about 50 mm, it can be judged as a normal rainy day, and the basic pumping rate can be maintained at a normal or low level.
Through the mode, the basic pumping rate of the pumping pump can be adjusted in advance by utilizing the weather information published by the network, so that the water can be discharged in time when sudden rainstorm or weather is larger, and the working power consumption of the pumping pump is reduced on the premise of meeting the use requirement when the rainfall is small.
In other embodiments, before determining the expected rainfall in the preset time period in the future according to the weather information, the method further includes:
acquiring historical average rainfall corresponding to different weather information; grading the historical average rainfall according to the historical average rainfall; and generating a mapping relation database between different weather information and different expected rainfall amounts based on the grading result.
For example, the expected rainfall corresponding to the red rainstorm warning is set as the highest level, and when the red rainstorm warning is received, the basic pumping rate can be set to the maximum rate directly through the mapping relation database. By establishing the mapping relation database based on the historical average rainfall, the expected rainfall corresponding to different weather information can be obtained by utilizing big data, so that the basic pumping speed of the pump can be accurately adjusted, and the intellectualization and the reliability of the pumping operation control are further improved.
Further, the base pumping rate of the drain pump needs to be greater than or equal to the expected rainfall to ensure the effectiveness of the pumping process.
In some embodiments, the control module 6 may be specifically configured to: when the third induction signal is received, setting a first placeholder; when a second induction signal is received, judging whether a first placeholder exists or not; if so, controlling the sewage pump 33 to set the first pumping speed; if not, controlling the sewage pump 33 to set the second pumping speed; wherein the first pumping rate is less than the second pumping rate.
Specifically, when receiving the third sensing signal, then can judge that present sewage treatment pond 4 has been in critical water level, if continue the drainage and probably make sewage treatment pond 4 transship, lead to the equipment in sewage treatment pond 4 to appear damaging. At this time, the sewage pump 33 is set at the second pumping rate, so that the rate of water discharge to the sewage treatment tank 4 can be temporarily reduced, and the water level of the sewage treatment tank 4 is controlled to be maintained at a reasonable position, thereby avoiding the occurrence of the situation that the equipment of the sewage treatment tank 4 is damaged due to the sewage discharge. And, through setting up first placeholder, also can be convenient for control module 6 to judge whether receive the condition of third sensing signal.
In addition, the storage time of the first placeholder can be set to be a preset time length, and if the third sensing signal is not received within the preset time length, the first placeholder is deleted. It can be understood that, when the third sensing signal is not received within the preset time period, it is possible that the water level of the sewage treatment tank 4 has dropped, and the water can be continuously drained to the sewage treatment tank 4.
In other embodiments, the control module 6 is further configured to: when the third induction signal is received, setting a first placeholder; when a first induction signal is received, judging whether a first placeholder exists or not; if so, controlling the sewage pump 33 to set the first pumping speed; if not, controlling the sewage pump 33 to set the second pumping speed; wherein the first pumping rate is less than the second pumping rate.
In this case, the first water level sensor is provided at a position of the drainage ditch 1 near the notch, and when the first sensing signal is received, the water level of the water collection well 2 may be low, but the water level of the drainage ditch 1 may be high, which may cause the water level of the water collection well 2 to suddenly rise in a short time. If detect first placeholder this moment, set up sewage pump 33 at the second rate of drawing water, can temporarily reduce the drainage rate to sewage treatment pond 4, control sewage treatment pond 4's water level and maintain reasonable position to avoid appearing the condition that the equipment of sewage treatment pond 4 that sewage crossed the row and cause damaged equally.
In some embodiments, the control system further comprises a sewage pump 33 triggering assembly. The sewage pump 33 trigger assembly is arranged at the bottom of the drainage ditch 1, is in communication connection with the control module 6, and is used for detecting whether water exists at the bottom of the drainage ditch 1; if yes, generating a sewage pump 33 trigger signal; the control module 6 is specifically configured to: monitoring a sewage pump 33 trigger signal; when receiving the trigger signal of the sewage pump 33, controlling the sewage pump 33 to be in a standby or working state; when the sewage pump 33 trigger signal is not received, the sewage pump 33 is controlled to be in a closed state.
By providing the sewage pump 33 trigger assembly at the bottom of the drain 1, it is possible to determine whether water is present at the bottom of the drain 1 and thus whether the current sewage pump 33 is likely to require a draining operation. If not, the sewage pump 33 may be turned off to save power and reduce the daily consumption of the sewage pump 33.
