Abstract
The utility model discloses a monitoring device for a liquid level of a nonmetal container and the device comprises a nonmetal container. A float is disposed in the container; a magnet is packaged in the float; the top end of an outside wall of the container is provided with a top end magnetic field sensor; the lower end of the outside wall of the container is provided with the lower end magnetic field sensor; and an output port of the top-end magnetic field sensor and the lower end magnetic field sensor is respectively connected with a one-chip microcomputer. Cooperation between the magnet in the float and the magnetic field sensors drives the one-chip microcomputer to work to display liquid level height, thereby further carrying out monitoring to liquid level height of container with higher sensitivity; and besides, a structure of the magnetic field sensor arranged on the outside wall of the container enables the device with simple structure, easy operation, great stability and long service life.
Description
Technical field
The utility model relates to container solution level monitoring technique field, relates in particular to a kind of nonmetallic vessel liquid level monitoring device.
Background technology
Liquid level control is process control common in the industry, fluid level controller carries out the control of two position by the method for mechanical type or electronic type, can control solenoid valve, water pump etc., thereby realize semi-automation or full-automation, it can not be ignored the impact of producing, and liquid level monitoring device is widely used in the industries such as household appliances, drinking equipment, sanitary bath equipment, chemical industry, food machinery, medical equipment, environmental protection equipment, industry control switch.Therefore, guarantee that fluid level control device high stability, high sensitivity, corrosion resistance are very important, in the existing fluid level control device, liquid level monitoring device must contact with liquid, therefore, so that liquid level monitoring device is corroded by solution easily, reduced the sensitivity of liquid level monitoring device, reduced the serviceable life of liquid level monitoring device.
The utility model content
For defects or deficiency, the utility model provides a kind of simple installation, good stability, highly sensitive nonmetallic vessel liquid level monitoring device.
For reaching above purpose, the technical solution of the utility model is:
Comprise: nonmetallic container, be placed with float in the container, be packaged with magnet in the float, the upper end of container outer wall is equipped with the upper end magnetic field sensor, the lower end of container outer wall is equipped with the lower end magnetic field sensor, and the output terminal of upper end magnetic field sensor and lower end magnetic field sensor all is connected with single-chip microcomputer.
Described upper end magnetic field sensor and lower end magnetic field sensor all are attached on the container outer wall.
Described upper end magnetic field sensor and lower end magnetic field sensor are Hall element.
Described magnet is permanent magnet.
Described single-chip microcomputer is AT89C52.
The utility model is by placing the float with magnet in nonmetallic container, and upper end magnetic field sensor and the lower end magnetic field sensor that matches with magnet is installed at container outer wall, when liquid level reaches the highest liquid level requirement, the magnetic line of force that magnet in the float produces sees through chamber wall so that induction drives the upper end magnetic field sensor, so that single-chip microcomputer work shows liquid level; When liquid level reaches the lowest water level requirement, the magnetic line of force that magnet in the float produces sees through chamber wall so that induction drives the lower end magnetic field sensor, so that single-chip microcomputer work shows liquid level, and then play monitoring to the height of liquid level in the container, and has higher sensitivity; In addition, easy for installation so this utility model is simple in structure owing to magnetic field sensor of the present utility model is arranged at outside the chamber wall, good stability, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model nonmetallic vessel liquid level monitoring device.
1 is container among the figure, and 2 is float, and 3 is magnet, and 4 is the upper end magnetic field sensor, and 5 is the lower end magnetic field sensor, and 6 is single-chip microcomputer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Referring to shown in Figure 1, the utility model provides a kind of nonmetallic vessel liquid level monitoring device, comprise: nonmetallic container 1, be placed with float 2 in the container 1, be packaged with magnet 3 in the float 2, the upper end of container 1 outer wall is equipped with upper end magnetic field sensor 4, and the lower end of container 1 outer wall is equipped with lower end magnetic field sensor 5, the output terminal of upper end magnetic field sensor 4 and lower end magnetic field sensor 5 all is connected with single-chip microcomputer 6, and single-chip microcomputer adopts AT89C52 in the utility model.Concrete, upper end magnetic field sensor 4 all is attached on container 1 outer wall with lower end magnetic field sensor 5 in the utility model, so that magnetic field sensor and container 1 outer wall close contact.
In order to improve detection sensitivity of the present utility model, upper end magnetic field sensor 4 in the utility model all describes as an example of Hall element example with lower end magnetic field sensor 5, magnet 3 adopts permanent magnet, also be not limited to this but basis is practical, as long as can match with magnet, the sensor that produces electric signal can both realize, for can so that magnet cooperate with sensor, container in the utility model is that non-metallic material is made, and for example makes for organic glass material or plastic material.
The course of work of the present utility model is:
During application, as shown in Figure 1, upper end Hall element 4 and lower end Hall element 5 tightly are attached to the outside of container 1 wall, permanent magnet 3 is equipped with in float 2 inside, can be along with the liquid level in the container 1 rises or descends, float 2 drives as the induction of upper end Hall element and lower end Hall element, so that upper end Hall element and lower end Hall element carry out work, upper end Hall element and lower end Hall element output signal are digital quantity or interrupt request singal, input simultaneously single-chip microcomputer 6, monitored by the liquid level of liquid in 6 pairs of containers 1 of single-chip microcomputer afterwards.
The nonmetallic vessel liquid level monitoring device that the utility model provides, can avoid the traditional liquid level supervising device to contact with liquid, only need Hall element is close to the outer wall of nonmetallic vessel, change with the height that detects liquid in container, thereby promptly and accurately send alerting signal, effectively prevent liquid spill or machine dry combustion method, avoided the corrosion of incrustation scale, can replace traditional ball float sensing and metal probe sensing, prolonged serviceable life, have simultaneously high stability, high sensitivity, can run through the container of non-metallic material.This system adopts mu balanced circuit to give the situation that single-chip microcomputer can not produce erroneous judgement the level of input exactly, because the AT89C52 single-chip microcomputer has four ports, 32 pins can design easily display system, simple installation, good stability, highly sensitive, well prolonged its serviceable life.
