Abstract
The present invention relates to a kind of refrigerating box chamber door induction alarm systems, suitable for all kinds of refrigerating boxes, the photoelectric sensor being close to including being located at reefer body inner wall at chamber door position, temperature sensor, wireless communication module and PLC controller are equipped in refrigerating box, audible alarm unit is installed at the top of refrigerating box, wireless communication module is connected to remote handset, and photoelectric sensor, temperature sensor, wireless communication module and audible alarm unit are respectively connected to PLC controller.The present invention is when in use, if chamber door is in opening, photoelectric sensor can sense that chamber door is opened, as chamber door is always maintained at opening, then photoelectric sensor sends signal to PLC controller, PLC controller control audible alarm unit sounds the alarm, and passes through wireless communication module and notify remote handset.If during refrigerating box normal use, temperature sensor senses are abnormal to the temperature inside the box, equally send alarm by PLC controller control, improve the security during use, ensure that cold storage effect.
Description
Technical field
The present invention relates to a kind of refrigerating box chamber door induction alarm system, suitable for all kinds of refrigerating boxes.
Background technology
Refrigerating box in use, the situation that chamber door is not closed completely may occur due to artificial or other reasons, from
And phenomena such as causing cool air leakage, the cold storage effect in refrigerating box is affected, all kinds of detection refrigerating box chamber doors existing at present close
The component of situation is closed, usually there is the shortcomings of complicated, cost is high, is unfavorable for popularization and uses.
The content of the invention
According to the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to：Offer one kind solves above-mentioned
Defect, it is simple in structure, the temperature conditions in the chamber door closing situation and case of refrigerating box can be detected, report can be sent when abnormal
The refrigerating box chamber door induction alarm system of alert signal.
The technical solution adopted by the present invention to solve the technical problems is：Refrigerating box chamber door induction alarm system, including position
The photoelectric sensor at chamber door position is close in reefer body inner wall, temperature sensor, radio communication mold are equipped in refrigerating box
Block and PLC controller, refrigerating box top are equipped with audible alarm unit, and wireless communication module is connected to remote handset, photoelectric transfer
Sensor, temperature sensor, wireless communication module and audible alarm unit are respectively connected to PLC controller.
As the preferred embodiment of the present invention, the audible alarm unit is the small-sized sound being embedded at the top of refrigerating box
Case.
Temperature sensor is equipped in each refrigeration lattice in the refrigerating box.It more can accurately sense refrigerating box
Interior temperature.
Use principle is：
In use, if chamber door is in opening, photoelectric sensor can sense that chamber door is opened, as chamber door is always maintained at
Opening, then photoelectric sensor to PLC controller send signal, PLC controller control audible alarm unit sound the alarm,
And pass through wireless communication module and notify remote handset.If during refrigerating box normal use, temperature sensor senses to case
Interior temperature anomaly is equally sounded the alarm by PLC controller control audible alarm unit, and is notified far by wireless communication module
Cheng Shouji.
Advantageous effect is possessed by the present invention：In the use of the present invention, if chamber door is in opening, photoelectric sensing
Device can sense that chamber door is opened, and if chamber door is always maintained at opening, then photoelectric sensor sends signal, PLC to PLC controller
Controller control audible alarm unit sounds the alarm, and passes through wireless communication module and notify remote handset.If in refrigerating box
During normal use, temperature sensor senses are abnormal to the temperature inside the box, equally by PLC controller control audible alarm unit hair
Go out alarm song, and remote handset is notified by wireless communication module, so as to improve the security during use, ensure that cold
Hide effect.
Description of the drawings
Fig. 1 is the electronic schematic diagram of the present invention.
Specific embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings：
Below by way of specific embodiment, the invention will be further described, but not to limit the present invention, it is all in the present invention
Within spirit and principle, any modifications, equivalent replacements and improvements are made should all be included in the protection scope of the present invention.
As shown in Figure 1, refrigerating box chamber door induction alarm system, is close to including being located at reefer body inner wall at chamber door position
Photoelectric sensor, temperature sensor, wireless communication module and PLC controller are equipped in refrigerating box, is equipped at the top of refrigerating box
Audible alarm unit, wireless communication module are connected to remote handset, photoelectric sensor, temperature sensor, wireless communication module and
Audible alarm unit is respectively connected to PLC controller.
Audible alarm unit is the small-size sound box being embedded at the top of refrigerating box.It is equipped in each refrigeration lattice in refrigerating box
Temperature sensor.
Use principle is：
In use, if chamber door is in opening, photoelectric sensor can sense that chamber door is opened, as chamber door is always maintained at
Opening, then photoelectric sensor to PLC controller send signal, PLC controller control audible alarm unit sound the alarm,
And pass through wireless communication module and notify remote handset.If during refrigerating box normal use, temperature sensor senses to case
Interior temperature anomaly is equally sounded the alarm by PLC controller control audible alarm unit, and is notified far by wireless communication module
Cheng Shouji.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
