Each of the reed switches 1110, 1120, 1130, and 1140 is provided with two contacts inside the glass tube and has a relatively small volume.

The azimuth management unit 1200 functions as a controller for monitoring and controlling the entire operation of the bicycle burglar alarm circuit unit 100. When a signal detected from the reed switch module 1100 is inputted, a stop signal is transmitted through the switch unit 1500 And controls the alarm unit 1400 until it is input to output an alarm signal.

The azimuth management unit 1200 includes a plurality of terminals connected to the functional units to input and output the signals, and specific indications for the respective terminals are not shown in the drawings.

The azimuth management unit 1200 determines whether a signal detected from the reed switch module 1100 is input according to a command signal input through the mode setting unit 1600. [

The azimuth angle management unit 1200 may be configured to detect an azimuth angle of the azimuth angle control unit 1200 when a signal detected from any one of the first to fourth reed switches 1110, 1120, 1130, and 1140, (1400) to output an alarm signal.

The azimuth management unit 1200 continuously outputs an alarm signal (alarm signal) until the corresponding command signal is input from the switch unit 1500, and the alarm signal may include general contents.

The linear motor module 1300 generates a driving force that moves in a straight line by the corresponding control signal of the azimuth management unit 1200. The generated linear driving force moves the linear mover in a forward and backward direction along the linear movement groove H .

The alarm unit 1400 amplifies the signals input through the PC0 to PC5 terminals (not shown) of the azimuth management unit 1200 with the Darlington array elements, and outputs an alarm signal because the buzzer is interrupted.

At this time, it is preferable to directly supply 3.3 volt operating power to the buzzer, and the relay may not be used.

The switch unit 1500 inputs a control command signal for blocking an alarm signal from being output from the alarm unit 1400 to the azimuth management unit 1200 so that a general switch configuration can be used. However, a membrane-type or tact- It is relatively preferable to use the bicycle in a bicycle having a small storage space.

When the switch is depressed, the voltage signal charged to the capacitor denoted by C5 through the resistance of 10 kilo ohms indicated by R20 is displayed as PD2 not shown in the drawing of the azimuth management unit 1200 through the resistor denoted by R21 Terminal.

The command signal input to the azimuth management unit 1200 through the mode setting unit 1600 may be adjusted to prevent the reed switch module 1100 from detecting or detecting the magnetic field in the current state by driving the linear motor module 1300.

The mode setting unit 1600 includes non-parity, 8-bit, (TTL) level signal at a data rate of 57600 bps.

The linear motor module 1300 is driven by the command signal input through the mode setting unit 1600 so that the reed switch module 1100 can be operated at a predetermined azimuthal displacement amount such as 15 degrees, 30 degrees, 45 degrees, 60 degrees, And it is relatively preferable to adjust to detect the azimuthal displacement amount of 30 degrees.

The azimuthal displacement amount detection is performed by setting the current state to the initial state and detecting the amount of displacement of the azimuth generated when moving.

The azimuth management unit 1200 may store all data collected during operation in an internally allocated memory and output the stored data to the outside through the data port unit 1700. [

The data port 1700 can input programs, operation data, and the like to the azimuth management unit 1200 from the outside, and can be used for other purposes selected by data communication as needed.

The mode display unit 1800 can visually display the power supply state, the error occurrence state, the detected azimuth angle value, and the like by the corresponding control signal of the azimuth management unit 1200.

The mode display unit 1800 is formed of LEDs and the states of the respective modes can be displayed in colors such as green, red, and amber. In the case of designing a state of low power consumption It may not be configured.
