Resistance rebound device.
Background technology
At present in Motor Control Field, on rolling screen door run be hampered bounce-back (or out of service) implementation method have with
Under it is several：
One kind is to realize that its structure is the conductor for having two quilts to separate up and down inside rubber strip, rubber using rubber strip
Bar is arranged on roller shutter door board bottom, when rolling screen door is descending, overwhelms barrier, rubber strip compressive deformation makes its internal separation
Conductor is contacted, and detection means is detected after conductor contact, is communicated with controller MCU, realizing that rolling screen door is descending by controller is hampered
Bounce-back.
One kind is realized using mechanical structure, installs several mechanical switch in roller shutter door board bottom, then install a bottom
Plate, bottom plate is connected with roller shutter door board bottom by spring, and mechanical switch, which is in, under normality closes (or opening) state, works as roller shutter
Door is descending, overwhelms after barrier, base plate spring is squeezed, and is in mechanical switch and opens (or closing) state, detection means
Detect switch to open after (or closing), communicated with controller MCU, the descending bounce-back that is hampered of rolling screen door is realized by controller.
One kind is realized using infrared emission, in a certain position of rolling screen door running track, installs an infrared emission dress
Put, in rolling screen door running, such as obstructed in infrared shooting device investigative range by barrier, controller just can detect infrared
Obstructed to penetrating by barrier, then realize that rolling screen door runs the bounce-back that is hampered.
Three of the above implementation method be present：Because the actual door body size of user is different, rubber strip is needed
Cut according to the size of rolling screen door door body, after installation, due to commonly using the easy aging of rubber strip, breakage, and can not
Good waterproof and moistureproof.The method that mechanical structure is realized, is also needed according to door body actual size, has bottom plate made to order, and machinery is opened
Close can not waterproof and moistureproof well, easily there is misoperation.The method that infrared emission is realized, because infrared acquisition scope has
Limit, has in certain dead angle, dead range and occurs to be detected during barrier, there is potential safety hazard.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of safe and reliable door roller resistance rebound device, its to
The structure of the actual door body in family relies on less, is easily installed, applied widely.
In order to solve the above technical problems, the present invention is realized as follows：It is of the present invention to be based on acceleration of gravity
The resistance rebound device for rolling door of sensor includes gravity accelerometer, the MCU of wireless transmitting function and built-in aerial, electricity
Pond.Resistance rebound device for rolling door is installed together with roller doors motor controller, motor of rolling shutter door, and achievable rolling screen door was run
Journey is hampered bounce-back.
The gravity accelerometer constitutes communication connection by the MCU of the buses such as I2C, SPI and wireless transmitting function；
The MCU connection built-in aerials of the wireless transmitting function；
The MCU of the wireless transmitting function constitutes wireless connections by built-in aerial and roller doors motor controller.
The resistance rebound device internal battery, powers to device circuit.
The MCU of the wireless transmitting function is the single-chip microcomputer with wireless transmitting function.
The roller doors motor controller is constituted with motor of rolling shutter door and electrically connected, for controlling rolling screen door to lift.
The roller doors motor controller includes common type controller and a kind of being imaged with WIFI based on network technology
The controller of camera function, the WIFI cameras constitute communication with roller doors motor controller and are connected；WIFI cameras are built-in with
One video acquisition device, an audio collecting device, a SD card and WIFI module.
The controller with WIFI camera functions can constitute communication with mobile phone control terminal and be connected.
The gravity accelerometer is able to detect that the change of acceleration, and the change of acceleration is converted into telecommunications
Number, and electric signal is calculated, analyzed, store the result in internal register, gone by the MCU with wireless transmitting function
Read acceleration transducer internal register data and carry out processing comparison, such as reach the setting numerical value of bounce-back, then pass through channel radio
News mode sends bounce-back instruction to rolling screen door controller, and the bounce-back action that is hampered is completed by rolling screen door controller.
The resistance rebound device for rolling door based on gravity accelerometer is arranged on the bottom of door body, when door body is closed
When closing rear someone and forcing open the door, the change of gravity accelerometer perception is gone to read number by the MCU with wireless transmitting function
According to by wireless communication mode, being sent to roller doors motor controller, the change with the power of roller doors motor controller memory storage
The numerical value of the setting of mathematical modeling is compared, and be can determine whether whether door body is in stolen status according to numerical value change, is judged to being stolen
When send sound and light alarm signal, and warning message can be sent to the mobile phone control terminal of user.
The positive effect of the present invention：Resistance rebound device for rolling door of the present invention based on gravity accelerometer,
By way of gravity accelerometer and wireless telecommunications are set, thoroughly solve traditional rolling screen door be hampered bounce-back scheme presence
The problem of, as long as the optional position not being rolled in roller shutter door board, the device is installed, just can realize that rolling screen door is hampered
Bounce-back；Resistance rebound device for rolling door is sealed using waterproof and dampproof shell, it is adaptable to more rugged environment.In tradition
In detection mode, the method for rubber strip and mechanical structure can only realize that one direction is hampered the i.e. descending bounce-back that is hampered of bounce-back, when running into
The door-plate OR gate of falling groove body suffers collision-deformed situation, and door-plate is up to be detected, door-plate by force on be about to produce it is certain
Loss, and change of the gravity accelerometer that the present invention is used to running acceleration is detected, no matter for door
Plate it is up or descending during can securely achieve the bounce-back that is hampered (or) stop, the antitheft inspection of rolling screen door can also be realized
Survey, this is also that conventional method is irrealizable.
