Description
Technical field
The utility model relates to a kind of household liquid level detection system, especially makes to use up reflective non-contact liquid level detection sensing module, and has the liquid level detection system of SMS alarm function.
Background technology
Along with society grows with each passing day to the demand of family expenses floods detection alarm, how to realize more quick, accurately, convenient, quick liquid level detection alarm ready-made problem demanding prompt solution.Existing liquid level detection alarm device is applied in high liquid level detection and the industry use more.The monitoring, alarming of rivers lake, dam, storage tank, cistern for example, the industrial liquid level of air-conditioning, accumulator etc. detects.Because family's floods have low liquid level, liquid level ascending velocity slow, this has just proposed high requirement to resolution, precision and the antijamming capability of liquid level detection device.Resolution is more high, and it is more timely to report to the police, and is disaster-stricken more light, and user's loss is also just more few.So the utility model proposes a kind of liquid level detection alarm system of suitable family expenses, can the situation of change of liquid level be detected fast,, be swift in response to User Alarms by note, thereby reduce user's loss.
Existing liquid level gauge or liquid level/liquid level alarm detector mostly is contact, as float-ball type liquid level sensor, electric pole type liquid level sensor, pressure reduction liquid level sensor etc., because the contact liquid level sensor directly contacts with fluid to be measured, so in use sensor surface dirt easy to hang, corrosion influence operate as normal.Touch sensor is when hanging down liquid level gauging simultaneously, and resolution and precision are lower.Be example with the electric pole type liquid level sensor, the electric pole type liquid level sensor has communicating pipe, along communicating pipe length direction and a string electrode that distributes communicating pipe as the liquid awareness tool, the electric pole type liquid level sensor is to utilize that the electric conductivity of the liquid that contacts with electrode or gas is different exports different liquid level signals, the deficiency of this sensor is that electrode directly contacts dirt easy to hang with liquid, hang dirt and easily make electrode conduction, measure inaccurate, the installation of electrode simultaneously and maintenance are also very difficult, cost is higher simultaneously, can't satisfy the needs of family expenses.
And existing contactless liquid level detection device adopts communication medias such as ultrasound wave, laser more, but volume is big, cost is high, complex structure, is unsuitable for household, the use of daily public place.Non-contact liquid level detection method based on the anaclasis formula has appearred for this reason, when the light that utilizes light source to send is slanted through another kind of medium from a kind of medium, velocity of propagation changes, thereby make light at different medium intersection generation deviation, thereby the light intensity that outgoing illumination is penetrated on light activated element change to reflect liquid level signal.But it is light-transmissive fluid that the liquid-level detecting method that is based on the anaclasis formula requires fluid to be measured, and depends on optical imaging lens.Owing to light exists diffuse reflection and light activated element than reasons such as sensitivities, only use light activated element as light-receiving member poor anti jamming capability, precision are not high, resolution is lower merely, can not the tracking of liquid level be detected, can't satisfy household floods detection alarm to resolution, precision needs.Detect though adopt linear array CCD or linearly aligned Fibre Optical Sensor can realize following the tracks of as improving one's methods of light-receiving member, increased cost simultaneously.
In sum, lack owing to the contact liquid level detection device exists dirt easy to hang, serviceable life, can't detect shortcomings such as corrosivity liquid, cost height; Contactless liquid level detection device exists then that volume is big, cost is high, relies on optical imaging lens, can only detect deficiencies such as light-transmissive fluid, poor anti jamming capability.The utility model makes to be used up reflective non-contact liquid level and detects sensing module and carry out the collection of liquid level information, has overcome above-mentioned deficiency effectively.
Use as household floods detection alarm device, especially among the manager nobody the time, rely on sound and light alarm merely, can't realize long-distance alarm.Use the GSM technology to address the above problem.When liquid level changes,
The GSM SMS transmission module can send alarming short message fast to user mobile phone, has satisfied the requirement of Rapid Alarm.
Summary of the invention
