Description

Storage cabinet lock based on Bluetooth communication

Technical Field

The utility model relates to a locker field, especially a locker lock based on bluetooth communication.

Background

In actual life, people often need to put their own articles in a storage cabinet, for example, when shopping in a supermarket, people need to store their articles temporarily. For example, during body-building, a personal mobile phone, clothes and the like need to be put into a wardrobe. Traditional locker lock adopts mechanical lock or electronic lock, and the actual installation uses work load very big, and for wired connection, the fault rate can be than higher, and the problem investigation is also more difficult. Traditional locker lock is general weight is heavy, and power consumption is big, and the requirement between hasp and the lock is also than higher, and is difficult during the installation, very easily appears the unable condition of popping open the door.

Currently, various cabinet locks have different short plates as follows: mechanical cabinet lock. The lock is suitable for occasions such as common letter and newspaper boxes and low-end storage, and special one-to-one keys are needed for opening cabinets. If the lock key is not used, the lock cannot be unlocked, delay is caused, and the lock key is taken at any time and is troublesome.

A card swiping type cabinet lock. Such an approach requires the use of pre-assigned ICs or ID cards, bracelets, etc. When needed, the cabinet can be opened by directly calling the card. The cabinet lock is an electromagnetic lock and is bounced open by the mechanical force of a spring in the lock. The IC card or the ID card is the only open cabinet mode. When the conditions such as loss appear, can't realize opening the door, and long-term use lock in the spring stress decline, have the problem that is difficult for opening the cabinet door. The cabinet control terminal is not needed, manual management can be achieved, and intelligent storage cannot be achieved.

Terminal drive-by-wire electromagnetic lock. The cabinet control terminal directly controls the lock control main board through 485 signals, and the lock control main board realizes the switch control of the lock. This scheme can realize intelligent storing, but the wiring is complicated, and the circuit is not too long, when having hundreds of cabinets, needs the connection communication problem of 485 signals of special attention, communication interruption scheduling problem appears easily. The cabinet door and cabinet lock is mechanically opened like IC cards.

Detailed Description

Embodiment 1, this embodiment is a locker lock based on bluetooth communication, as shown in fig. 1, this locker lock based on bluetooth communication has a control terminal that removes, the control terminal that removes at present generally uses the APP of installation lock on a cell-phone, utilize the built-in bluetooth chip of cell-phone to realize realizing with the bluetooth communication module in the lock and realize communicating, in the control circuit of the motor drive of sending the order of unblanking and shutting to the lock, in the control circuit of the motor drive, have an intelligent treater MCU, it receives the control order that the cell-phone sent through bluetooth communication module, control motor work after discerning, realize unblanking and shutting.

In the embodiment, the storage cabinet lock based on the bluetooth communication is composed of a shell, a motor transmission, a bluetooth communication module and an interface circuit.

The shell part is made of ABS material, and is compression-resistant, fireproof and durable. The housing is self-contained with a battery slot. The machine adopts 4 sections of 1.5V dry batteries for power supply, also can adopt rechargeable batteries, and is provided with a temporary charging interface. Is very convenient and practical.

The motor transmission adopts a low-voltage low-power consumption direct current motor, and torque conversion is realized through a gear set. The small motor has enough driving capability. The change of direction of force is realized by the worm, and the change of direction of force is converted from circular motion to linear motion. The extension and contraction of the reed can be directly realized, and then the opening and closing of the cabinet door can be realized. As shown in fig. 2, a worm gear 200 is disposed on an output shaft 100 of the motor 100, the worm gear 200 drives a speed change mechanism 300 formed by sequentially engaging a first gear 301, a second gear 302 and a third gear 303, and a sliding rod 400, a sliding block 500 sliding on the sliding rod 400, a rack 501 engaged with the third gear 303 of the speed change mechanism 300 and a shift lever 502 fixed to a latch 600 are disposed at an upper end of the sliding block 500. The motor 100 transmits torque to the speed change mechanism 300 through the worm 200, the speed change mechanism 300 drives the sliding block 500 to slide on the sliding rod 400 through the rack 501 engaged with the speed change mechanism 300 through the conversion of the transmission ratio, and the driving bolt 600 is driven to extend or retract to realize locking or unlocking due to the action of the driving lever 502. In addition, a return spring 700 is included, which can directly lock the lock when the cabinet is closed.

The Bluetooth communication module is a core communication module in the machine. A JDY-19 chip is adopted, and a micro singlechip MCU is adopted as a host control end of the Bluetooth at the periphery. The command issuing and call-back are realized for each Bluetooth ID number through the corresponding command, and then the correct control on the cabinet lock is realized. The block diagram of the bluetooth communication module and the control module is shown in fig. 3, in this embodiment, a 6V battery pack is used for supplying power to the motor driving module, meanwhile, a DC/DC circuit is used for converting 6VDC into 3.3VDC to supply power to the bluetooth chip and the MCU, the bluetooth module receives a wireless command of an external terminal under the control of the MCU, the MCU generates a control switch signal to the driving circuit, and the driving circuit drives the motor to unlock and lock.

The product of this embodiment has the following characteristics: replacing the previous discrete design with an integrated solution. The consistency of the whole machine is improved, and various inconveniences in the actual use process, such as wiring, installation, signal interference and the like, are solved.

The unlocking mode is changed from mechanical elasticity into electromotion by utilizing the motor screw, so that the mechanical problem is solved.

The cabinet control terminal realizes management in an ID name mode through a wireless ID distribution mode, and is very convenient to search. Replaces the original mechanical numbering and has a large number of connections.

The wireless mode is changed into the wired mode, the great wiring of the installation workload is realized, and the debugging process is changed into a direct terminal connection ID naming mode.

The manpower cost is greatly saved. For example, 200 cabinets are arranged in a venue, the manual installation and debugging time is 4 days, and the Bluetooth lock is used, so that the installation and debugging can be completed in one day.

Bluetooth low energy mode, in no command state, will carry out the standby dormancy. The electromagnetic lock for spinning has the advantages that the electric energy required for unlocking is 12V 2A, and the duration is 2S. Namely 24W, while the bluetooth lock in the embodiment only needs 4 dry batteries to work for half a year.

The bluetooth adopted in this embodiment is the most widely used wireless communication mode at present. Although the technology is mature, the transmission is reliable and stable; but the distance of transmission is relatively short. An improved scheme is needed if long-range bluetooth transmission needs to be implemented.

Because the work scene is indoor in the present case, can effectively realize. If a greater distance is required: bluetooth relay is used. And carrying out segmented transmission on the signals.

Other internet of things transport protocols such as L ORA are used.
