Description
Technical field
It the utility model is related to electrical circuitry equipment security fields, and in particular to a kind of secure latch loosens attention device.
Background technology
Secure latch is the important component of the protection tools such as safety belt, safety rope, and whether its quality and lock snap into
Position drastically influence the personal safety of operator, but existing safety belt, safety rope secure latch, be generally only machinery
Structure, monitoring device is not equipped with, once loosening and releasing, wearer knows nothing, and easily triggers accident, gently then by severely injured, endangers
Life.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of secure latch loosening attention device, and its is easy for installation,
Suitable for polytype lock, alarm can be sent when safety belt is opened or is loosened, the personal safety of operating personnel is effectively ensured.
Therefore, the technical solution of the utility model is as follows：
A kind of secure latch loosens attention device, including base, Hall sensor and control unit；
The bottom surface of the base is curved surface, and its shape and the external surface shape of secure latch to be installed match；It is described
Base is using magnetic attracting on secure latch；
The Hall sensor is arranged on the base, and is connected with the control unit；
For the control unit integrated installation in box body, the box body can be installed on the safety that the secure latch is installed
Take；
The control unit include be sequentially connected operational amplifier, filter circuit module, detecting circuit module, microcontroller
Unit (MCU) and alarm module；The output end of the Hall sensor is connected with operational amplifier, will receive signal transmit to
Operational amplifier amplifies, and the signal after amplification transmits after the filter circuit module noise reduction, detecting circuit module selection
To the micro-control unit；Judgement is compared with preset data after receiving signal for the micro-control unit, when being judged as pacifying
When full lock is opened or loosened, the micro-control unit sends signal to the alarm module, starts the alarm module and sends
Warn sound.
Further, the control unit also includes buckle diameter selecting module, the buckle diameter selecting module with it is described
Micro-control unit is connected, for making micro-control unit judge whether secure latch is opened or preset data and reality used in loosening
The secure latch that border uses matches.
Further, the alarm module is buzzer or voice alarm module.
The secure latch, which loosens attention device, can realize easy disassembly, can attach it to safety belt, on safety rope or with oneself
Wear, when secure latch is opened or loosens (loose contact is good), can give a warning, staff serves to safety work
Good warning function, contribute to raising safety of avoiding risk in time.It is totally enclosed type that the secure latch, which loosens attention device, work
Personnel can not be manually operated, and only when secure latch fastens again, alarm call can just eliminate.
Brief description of the drawings
Fig. 1 is the structured flowchart that secure latch provided by the utility model loosens attention device；
Fig. 2 is the installment state figure that secure latch provided by the utility model loosens attention device；
Fig. 3 is the enlarged drawing of Hall sensor and base.
Embodiment
The technical solution of the utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in figure 1, a kind of secure latch loosens attention device, including base 3, Hall sensor 4 and control unit；Base
3 bottom surface is curved surface, and its shape and the external surface shape of secure latch 1 to be installed match；Base 3 is existed using magnetic attracting
On secure latch 1；Hall sensor 4 is installed on the base 3, and is connected with control unit；Control unit integrated installation is in box body
Interior, box body can be installed on the safety belt that secure latch is installed；Control unit includes operational amplifier, the filtering being sequentially connected
Circuit module, detecting circuit module, micro-control unit (MCU) and alarm module；The output end and operation amplifier of Hall sensor
Device is connected, and will receive signal and transmits to operational amplifier and amplifies, the filtered circuit module noise reduction of signal, detection electricity after amplification
Transmitted after the module selection of road to micro-control unit；Judgement is compared with preset data after receiving signal for micro-control unit, when
When being judged as that secure latch is opened or loosened, micro-control unit sends signal to alarm module, starts alarm module and sends warning
Sound.Further, alarm module is buzzer or voice alarm module.
During implementation, in order to adapt to the use of the safe block button of different-diameter, control unit also includes buckle diameter selection mould
Block, buckle diameter selecting module are connected with micro-control unit, for make micro-control unit judge secure latch whether open or pine
Preset data used in dynamic matches with the secure latch actually used.
In use, when the dead bolt 2 of secure latch 1 unclamps or opened out of lock, cutting magnetic line, Hall sensor connects
After receiving field variation signal, transmit it to operational amplifier and amplify, the filtered circuit module noise reduction of signal after amplification, so
Transmitted again after detecting circuit module selects suitable signal to micro-control unit afterwards；Micro-control unit receive after signal with it is pre-
If judgement is compared in data, when being judged as that secure latch is opened or loosened, micro-control unit sends signal to alarm module,
Start alarm module and send warning sound.When dead bolt 2 buckles into lock 1, without field variation, alarm module stops sending warning
Sound.
