Abstract

The invention discloses a SCM (Single Chip Microcomputer)-based theft prevention lock with the low power consumption. The theft prevention lock is mounted in the wheel shaft of a vehicle body and comprises a controller, a driver, a stepping motor and a wireless remote controller, wherein an encoder is arranged in the wireless remote controller; a decoder is arranged in the controller; the wireless remote controller is used for sending out a control command through an antenna by utilizing the encoder; the decoder is used for sending a motion control command after receiving the control command; the controller is used for receiving the motion control command, processing the command and then sending the command to the driver; and the driver is used for controlling the stepping motor to work according to the command, thereby realizing the manipulation to a mechanical structure. Therefore, the wheel shaft of the vehicle body is locked. The MSP430 SCM is adopted by the controller. The theft prevention lock disclosed by the invention has the beneficial effects that the lock can be used for a super long time while working with the low power consumption, so that the use reliability is ensured; the lock is convenient to operate, i.e., the complicated key operation process is omitted while only the remote controller is applicable, so that the only requirement for locking and unlocking the key is to press a button; and the lock is accurate in control, i.e., the SCM is used for accurately controlling the mechanical structure to work, so that the problem that the lock cannot be locked is avoided.

Description

SCM Based low-power consumption theftproof lock

Technical field

The present invention relates to a kind of SCM Based low-power consumption theftproof lock.

Background technology

At present, the stolen problem of bicycle, electric bicycle and motorcycle is more and more serious, the widely used lock such as bicycle, electric motor car is the lock that separates with car body, even the lock that car body carries also is based on the lock of key, the lock that exposes is easily cut off with the high pressure gas pincers by the robber, easily is opened and destroys.Now, the intelligent anti-theft lock that is embedded in car body is also less, also has the shortcomings such as power consumption is larger even have.

Summary of the invention

Purpose of the present invention is exactly in order to address the above problem, and a kind of SCM Based low-power consumption theftproof lock is provided, and it has advantages of antitheft.

To achieve these goals, the present invention adopts following technical scheme:

A kind of SCM Based low-power consumption theftproof lock is arranged in the car body wheel shaft, comprises controller, driver, stepper motor, Digiplex; Described Digiplex built-in encoder, the built-in demoder of described controller, described Digiplex sends steering order by scrambler by antenna, after receiving, demoder sends motion control instruction, controller receives motion control instruction, after the controller processing instruction, controller sends instruction to driver, and driver is according to instruction control step machine operation; The manipulation of realization to mechanical framework, thus realize pinning the car body wheel shaft, and described controller is selected the MSP430 single-chip microcomputer.

Beneficial effect of the present invention:

The installation site: be arranged in the car body wheel shaft, the robber can not find easily, and is safe and reliable; Based Intelligent Control: adopt the MSP430 ultra low-power microcontroller as primary controller, adopt wireless telecommunications to control the switch of lock, convenient, flexible; The power consumption aspect: low-power consumption work, realize that the ultra-long time of lock uses, guarantee dependability; Easy to operate: this lock is abandoned key operated complex process, only is suitable for telepilot, and button can be realized switch lock; Control precisely: precisely control mechanical arrangement works by single-chip microcomputer, the problem that does not exist lock not go up; Waterproof cooling: this device and possess waterproof, heat sinking function, get rid of because of water or the overheated device damage that causes.

Embodiment

The invention will be further described below in conjunction with accompanying drawing and embodiment.

As shown in Figure 1, a kind of SCM Based low-power consumption theftproof lock is arranged in the car body wheel shaft, comprises controller 3, driver 4, stepper motor 5, Digiplex 2; Described Digiplex 2 built-in encoders 1, the built-in demoder 6 of described controller 3, described Digiplex 2 sends steering order by scrambler 1 by antenna, after receiving, demoder 6 sends motion control instruction, controller 3 receives motion control instruction, after controller 3 processing instructions, controller 3 sends instruction to driver 4, and driver 4 is according to 5 work of instruction control step motor; The manipulation of realization to mechanical framework, thus realize pinning the car body wheel shaft, and described controller 3 is selected the MSP430 single-chip microcomputer.

Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
