A WSN float liquid level detection device and method for environmental protection

Abstract

The invention discloses a device and method of WSN float liquid level detection for environmental protection. Two downwards perpendicular sliding rails are laid on a sliding rail support. The center of gravity portion of a baffle support is fixedly connected with the lower end of a steel wire rope and the upper end of the steel wire rope is connected with a wire winding guiding wheel upwards in a perpendicular mode. The lower end of each right-angle contact support is provided with one liquid level contact. The two liquid level contacts are arranged face to face in a vertically perpendicular mode. The lifting of a liquid level drives a spring to generate elastic deformation, the position of a liquid level pointer is changed, so that a control system device is driven to generate different control operations, the wire winding guiding wheel is driven to rotate so as to reel the transmission steel wire rope in or reel the transmission steel wire rope out until the deformed spring recovers to a natural state, and finally the liquid level pointer is separated from an induction contact. The fluctuation condition of the liquid level is judged and monitored through the elastic deformation of the spring, the displacement of change of the liquid level is calibrated through control of pulse count of a stepping motor, adjustment is simple, transmission is accurate, and the device of WSN float liquid level detection for environmental protection has the advantages of microminiaturization, intelligence-orientation and continuous work.

Description

technical field [0001] The present invention relates to the field of liquid level measurement and the field of environmental protection, in particular to a WSN (wireless sensor) float liquid level detection device and method for environmental protection, which is widely used in various fields such as chemical industry, medicine, water company, hydrological station, etc. Level measurement of media. Background technique [0002] Liquid level detection devices are generally used in places with harsh environments and severe pollution, especially water level monitoring stations. The accuracy of water level detection values ​​provides valuable reference value for alarm or decision-making during flood seasons, especially in central areas far away from monitoring points. In the control room, the remote transmission effect of the signal is high and the failure rate is low. The existing liquid level detection device generally fixes two wheels with different diameters on the rope whee...

Problems solved by technology

However, the resistance value of this float type liquid level gauge is greatly affected by temperature changes, which affects the accuracy; the magnetic shaft or metal shaft and the guide rod are sliding friction, and the friction force is large; electric sparks may be generated when sliding, and cannot be used in explosion-proof occasions.
