Accompanying drawing explanation
Shown in Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing of the present utility model; clear, complete description and discussion are carried out to the technical scheme in the utility model embodiment; obviously; as described herein is only a part of example of the present utility model; it is not whole examples; based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to protection domain of the present utility model.
For the ease of the understanding to the utility model embodiment, be further explained for specific embodiment below in conjunction with accompanying drawing, and each embodiment does not form the restriction to the utility model embodiment.
As shown in Figure 1, the constant pressure water supplying device based on Internet of Things that the utility model provides, comprising: bottom limit level sensor 11, upper limit level sensor 12, main control MCU 2, electromagnetic valve 3, frequency converter 4, water pump 5, gate valve 6, flap valve 7, pressure sensor 8, communication apparatus 9, server 101, mobile client 103, pc client 102.
Bottom limit level sensor 11, upper limit level sensor 12 are electrode sensor, be used for respectively detecting the liquid level in water tank, when the position of liquid level lower than bottom limit level sensor 11, main control MCU 2 is opened electromagnetic valve 3 and is intake, when the position of liquid level higher than upper limit level sensor 12, main control MCU 2 shut electromagnetic valve 3, thus the water level in guarantee water tank is in suitable scope.
In the present embodiment, water tank has the outlet pipeline of three tunnel parallel connections, but the utility model is not as limit.Every road outlet pipeline comprises successively gate valve 6, water pump 5, flap valve 7 and another gate valve 6, flap valve 7 is used for preventing aqueous reflux, and the end of three road outlet pipelines merges into a road.Three water pumps 5 connect frequency converter 4, main control MCU 2 obtains the hydraulic pressure of three road outlet pipeline ends by pressure sensor, and progressively regulate the speed of water pump 5 by frequency converter 4 and open number, regulate by the classification of the continuous adjustment of frequency converter and water pump quantity within the scope of full flow, feed pressure is remained in setting value.
Operating principle of the present utility model is as follows: first detected the liquid level in water tank by bottom limit level sensor 11, upper limit level sensor 12, the predetermined upper limit, lower limit whether is arrived according to liquid level, carried out the switch of Controlling solenoid valve 3 by main control MCU 2, the liquid level in water tank is maintained between the upper limit and lower limit all the time.Simultaneously, detect the hydraulic pressure of use water according to the pressure sensor 8 of outlet pipeline end, thus regulated the motor speed of water pump 5 by frequency converter 4 continuously, and the unlatching quantity of water pump 5, thus the hydraulic pressure of maintenance outlet pipeline end is in a predetermined value, stable water pressure during guarantee user's water.
Pressure sensor 8 can the hydraulic pressure of witness mark in real time, and convert thereof into the analog signals of 5-20MA, the A/D modular converter carried so again this signal being passed to main control MCU 2 processes, and can carry out the work controlling water pump 5 like this by frequency converter.
By communication apparatus 9 in real time by the liquid level information of water tank and the hydraulic pressure information transmission of feedwater to server 101, mobile terminal 103 and PC terminal 102 are from obtaining information server 101, main control MCU 2 also can too low in liquid level, too high time send alarm signal to mobile terminal 103 and PC terminal 102, realize remote monitoring.Meanwhile, mobile terminal 103 and PC terminal 102 can control main control MCU 2 by the mode of Long-distance Control, realize artificial control mode.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
