Specific embodiment

Technical solutions of the utility model are described in detail below by attached drawing, but the protection scope of the utility model It is not limited to the embodiment.

Embodiment 1: a kind of intelligent wireless patch lock, as shown in Figure 1, including mobile terminal, WIFI module, controller, electricity Machine drive module, current detection module and electric machine assembly, the electric machine assembly include direct current generator and connect with direct current generator Lock body.The mobile terminal is connect with WIFI module, and the output port of WIFI module and the input port of controller are connected and realized The transmission of data, the output port of controller and the input port of motor drive module connect, and motor drive module connects electric current Detection module, current detection module are connected to direct current generator.User is mounted on patch by the application program on mobile terminal The WIFI module locked issues the instruction unlocked or shut, and WIFI module sends controller to after receiving command signal, controls Digital information is sent to motor drive module after being handled by device, and motor drive module controls the rotation of direct current generator, direct current Motor drives lock body rotation to realize unlocking function.

Application program is installed, the application program plays bridge beam action between user and lock in the mobile terminal. Mobile terminal patch lock WIFI coverage area in establish WIFI connection after, can with patch lock WIFI module establish uniquely, can Socket connection lean on, stable, safe, and reliable and secure data are transmitted by Socket connection.The application program It is write by Java language, Android SDK compiling.The WIFI module that application program has by Android mobile phone, by mobile terminal The WIFI module standby with patch lockset is established after WIFI connect, can normal use application.In patch lock hardware, lead to The default IP address and PORT port numbers that can establish Socket connection of AT command set is crossed to pass through after keying in respectively in APP The asynchronous load data of RxAndroid complete login function；After login, Socket connection, patch lock are established after homepage creation Application interface responds click event by monitor, and response data is sent to buffer area；Socket obtains the interior of buffer area Hold, when issuing initialization Socket connection from WIFI module, Socket connection obtains the content in iostream and passes through RxAndroid asynchronous controlling completes the switch operation of lock.

The WIFI module uses model ESP8266-01 module, and WIFI module is mounted on patch lock lock body, is used for The rs 232 serial interface signal for receiving mobile terminal transmission carrys out the power on and off of control single chip computer.The working principle of the WIFI module: every time When single-chip microcontroller restarts, WIFI module is in standby；Single-chip microcontroller sends the AT kept in advance to WIFI module and refers to It enables, keeps WIFI module in running order.

The model of the single-chip microcontroller uses the single-chip microcontroller of STC90C516RD+, Calling AT instruction control WIFI mould The starting of block and reception signal, so that single-chip microcontroller can receive the signal from mobile terminal.Meanwhile single-chip microcontroller passes through control The low and high level of I/O port processed come control motor drive module with control motor rotation, to realize the rotation of lock body, reach unlocking Purpose.

The detected end connection direct current generator load of the current detection module, current detection module normal operation Under, when tested electric current is greater than cut-off operating current, relay is attracted；When tested electric current is less than running current, relay Device disconnects.When electric current is greater than current threshold, direct current generator power-off；When receiving electric signal again, direct current generator restores work Make, to guarantee circuit under safe current.
