Description

Water level monitoring and early warning platform system

Technical Field

In the fields of various production and municipal facilities, in order to ensure smoothness of a sewage well, the water level depth of the sewage well is generally monitored by a manual mode or a mode of installing monitoring equipment. The manual detection has the defects of time and labor waste, lower working efficiency and single detected data (only the water level height data in the current time period can be detected), so that the application of the manual detection has a great disadvantage.

In the existing advanced water level monitoring technology, the monitoring of the water level height change is generally carried out by adopting equipment based on a laser range finder module, when the liquid level height of a monitored area sewage well or the like changes in specific work, the detection head of the laser range finder module outputs a dynamically-changed analog voltage signal to the main control module after detecting the liquid level height, and then the main control module carries out AD conversion on the signal and then carries out remote transmission through a wireless mobile network, after receiving data, the intelligent mobile phone or a PC (personal computer) of a far-end related person can know the water level depth of the site in real time, and the site is treated timely when needed. The above monitoring mode, although meeting the requirements of data acquisition and transmission to a certain extent, is limited by the structure, and also has a certain specific problem to be solved, which is mainly reflected as follows. When the temperature of the detection head of the laser range finder module is lower than 0 ℃ in the field, condensation is generated at the front end of the detection head, even the icing is caused by overlarge moisture, and then the emission of the emission head (actually, the emission head and the receiving head are parallel) of the laser range finder module and the receiving head receive laser signals are influenced, so that the reality of water level monitoring data of a monitoring area is correspondingly adversely affected. The applicant inputs keywords 'sewage water level monitoring and early warning' in national patent office websites and hundred-degree related websites, and does not search the technical scheme similar to the application, so that the equipment capable of effectively ensuring the stable operation of the laser range finder module and achieving a relatively more accurate water level depth monitoring effect is particularly necessary.

In the utility model, as shown in fig. 1 and 2, the solar panel G1 is used for supplying power and the storage battery G2 is used for storing power, so that a power supply circuit is not required to be erected, the installation and the use are more convenient, and the energy is saved. The power output by the storage battery G2 enters the power input ends of the singlechip modules A2 and 5G module A3, the laser range finder module A1, the data conversion circuit and the control circuit, and the circuits and the modules work electrically. When the laser range finder module A1 works, the water level depth of a deep water well can be detected in real time, and when the depth of the deep water well is large, the distance between the water surface and the laser beam emitted by the emitter of the laser range finder module A1 is relatively close, so that the voltage signal output by the 3 pin of the laser range finder module A1 is relatively high, and conversely, the voltage signal output by the 3 pin of the laser range finder module A1 is relatively low (the voltage signal output by the 3 pin of the laser range finder module A1 is divided by the adjustable resistor RP1 and the resistor R1, and the voltage and the current are reduced by the resistor R2); after the dynamically-changed voltage signal enters the signal input end of the singlechip module A1, the singlechip module A1 converts the input analog voltage signal into a digital signal and outputs the digital signal to the 5G module A3, the 5G module A3 remotely transmits the input signal through a wireless mobile network, a far-end worker can inquire the water level data of a deep well on site through the application of a PC (personal computer) or a smart phone and the like by the existing mature data transceiving technology in real time, and the higher the number or the higher the waveform diagram displayed by the application display interface of the PC or the smart phone and the like respectively, the higher the water level of the deep well on the scene is represented, and conversely, the lower the water level of the deep well is represented.

Through the above, the application can grasp the field data in real time, and does not need to manually acquire the data on site, thereby bringing convenience to staff, and saving the cost of manually acquiring the data on site (the situation that the water level on site is too high represents the possibility of blocking the pipeline at the rear end of the deep well, the water level is too low represents the possibility of blocking the pipeline at the front end of the deep well, and the staff can dredge in time).

As shown in fig. 1 and 2, when the temperature near the deep water well is higher than 0 ℃ (the temperature is relatively difficult to generate condensation, vapor icing and the like), the internal contact of the temperature switch W (the temperature sensing surface is positioned outside the open hole at the front end of the element box) is open, so that the relay K1 cannot be powered, and the subsequent motor speed reducing mechanism and the electric heating plate cannot work. When the field temperature is lower than 0 ℃, the internal contact of the temperature switch W is closed, so that the control power input end and the normally open contact end of the relay K1 are electrically attracted, the electric heating plate RT generates heat, and the periphery of the transmitting head of the laser range finder module A1 is heated and insulated; when the temperature is higher than 0 ℃ again, the internal contact of the temperature switch W is opened again, so that the electric heating plate RT is powered off again and does not heat for heat preservation; through the above, the utility model discloses just can keep the temperature around the transmitting head of laser rangefinder module A1 automatically when on-the-spot temperature is too low. After the relay K1 gets the electricity, 3 feet of time relay module A4 are input high level signal, and then the 9 feet of time relay module A4 can output 6 seconds power (time technician is adjustable) and get into motor reduction gears M's power input, motor reduction gears M drives brush 4 and rotates round and stop (back brush and motor reduction gears are in vertical straight line around stopping, can not cause the influence to laser beam that laser rangefinder module A1's transmitter sent out), in the rotation process, the cotton brush hair upper end of brush contacts laser rangefinder module A1's transmitting head lower extreme, the transmitting head can be cleaned, the probability that the transmitting head (including the receiving head) to laser rangefinder module A1 caused dirty because of dust etc. has been reduced, and then the data that leads to laser rangefinder module A1 to monitor appear the variation. Through the above, when on-site temperature is lower than certain, this novel automatic power that switches on the electrical heating board has effectively prevented laser rangefinder module transmitting head condensation and has frozen, has guaranteed that the data of gathering is more true effective, has played favourable technical support for the complete steady operation of drainage well.
