Abstract
The utility model relates to a water level monitoring system with an upper water level limit protection function. The water level monitoring system is used for measuring a water level in real time by using ultrasonic sensors. The ultrasonic sensors are placed on the top of a water tank, the emitting direction of ultrasonic waves is over against the water surface, the three ultrasonic sensors are adopted in the system in order to reduce errors, the ultrasonic sensors are used for measuring, and then, an average value is calculated. When the water level is reduced to a scheduled lower limit value, a corresponding lower limit signal can be triggered, and a master controller can control a water pump to supply water for the water tank after receiving the signal. When the water level rises to a scheduled upper limit value, a corresponding upper limit signal can be triggered, and the master controller can control the water pump to stop supplying water for the water tank after receiving the signal. If the water level is up to the scheduled upper limit value and the master controller does not receive the signal for some reason, the water level continues to rise, the corresponding sensor can send out a signal when the water level is risen to an upper water level limit protection position, at the moment, the master controller can immediately stop supplying water, and thus, a protection measure is realized.
Description
Technical field
The present invention relates to electronic applications, refer in particular to a kind of water level monitoring system with the measure of water level upscale protection.
Background technology
Feedwater is a very general also very common activity, as the cistern feeding of family life, and the feedwater of solar water heater, the feedwater of fish jar, feedwater that factory uses etc.Water level monitoring is part and parcel in water supply system.If do not realize that water level monitoring and control thereof will cause great water resource waste.The shortcomings such as on market, water level monitoring system commonly used generally all is based on the sensor of contact now, and this class sensor has precision low, and serviceable life is low.Precision is high, and the life-span, the system that looks had again cost large, the characteristics that maintenance is complicated.
The present invention has developed a kind of water level monitoring system with the measure of water level upscale protection.This monitoring system has good precision and cost performance, due to safeguard measure being arranged, has also extended to a large extent the serviceable life of sensor.Through inquiry, have no Patents and deliver.
Summary of the invention
The invention relates to a kind of water level monitoring system with the protection of reaching the standard grade, this sensed water level system adopts touchless ultrasonic sensor, real-time measurement water level.When water level drops to the predetermined lower bound value, will trigger corresponding lower limited signal, primary controller receives can be controlled water pump after this signal and carry out water supply to water tank.When water level rises to predetermined higher limit, will trigger the signal of the corresponding upper limit, primary controller receives can be controlled water pump after this signal and stop water supply to water tank.When if water level reaches predetermined upper limit value, and primary controller does not receive this signal for a certain reason, and water level continues to rise; when the local time that rises to the water level upscale protection; send signal by corresponding sensor, primary controller will stop supplying water immediately, reaches safeguard measure.
The top of water tank is fixed three and is faced water surface ultrasonic sensor, and the sensor of a water level upper limit is separately arranged, and is placed on apart from the about 10cm place of tank top; The signal wire of four sensors is connected on corresponding pin on single-chip microcomputer, and the output signal pin of single-chip microcomputer is connected on the control pin of relay, and the other end pin of relay is connecting the power lead of water pump, is used for controlling the unlatching of water pump and stopping.
Further, comprise that also one is used for showing water level 1602 liquid crystal display.

Fig. 1 water level monitoring schematic diagram; Fig. 2 water level monitoring circuit schematic diagram.
Embodiment
Three ultrasonic sensors 1 are fixed on the top of water tank, sensor faces the water surface, and the position of three ultrasonic sensors 1 roughly is arranged in the top of water tank uniformly.The sensor 3 of the water level upper limit is placed on apart from the about 10cm place of tank top, but Self-adjustment, mainly for the protection of ultrasonic sensor and avoid the waste of water resource.The signal wire of four sensors is connected on corresponding pin on single-chip microcomputer 2, output signal pin with single-chip microcomputer 2 is connected on the control pin of relay again, the other end pin of relay is connecting the power lead of water pump 4, is used for controlling the unlatching of water pump 4 and stopping.Connect 1602 liquid crystal display, be used for showing water level.To system and water pump 4 energisings, this has just realized the system of water level monitoring, self water feeding and upscale protection again.
Claims (2)
1. water level monitoring system with water level upscale protection, the top that it is characterized in that water tank is fixed three and is faced water surface ultrasonic sensor, and the sensor of a water level upper limit is separately arranged, and is placed on apart from the about 10cm place of tank top; The signal wire of four sensors is connected on corresponding pin on single-chip microcomputer, and the output signal pin of single-chip microcomputer is connected on the control pin of relay, and the other end pin of relay is connecting the power lead of water pump, is used for controlling the unlatching of water pump and stopping.
2. the water level monitoring system with water level upscale protection as claimed in claim 1, characterized by further comprising one for 1602 liquid crystal display that show water level.
