However, the accompanying drawings are only illustrative of the embodiments of the present invention in detail, and the scope of the present invention is not limited or limited by the drawings or the description with reference to the drawings.

First, referring to FIG. 8, a motion detection module configuration according to the present invention will be described. For convenience of description, the motion detection module 100 sensing operation flow will also be described.

First, a power supply unit 600 for converting an AC power applied for driving a sensing module circuit and a sensor into a DC power is provided. The local signal generator 810 composed of active elements by the power supply from the power supply unit 600 oscillates continuously the microwaves, in this case, the frequency of the microwaves oscillated by the local signal generator 810 is It is preferable to set it to 10.525 GHz.

An antenna transmitter 710 which is a passive element for transmitting the frequency generated by the local signal generator 810 to a space, and an antenna receiver which is a passive element for receiving a signal transmitted from the antenna transmitter 710. 720).

The frequency mixer 820 mixes the frequency output signal and the frequency transmitted from the transmission frequency returned after the target is fired to the target to perform the conversion of the center frequency. That is, the microwave signal is converted into an intermediate frequency by using the microwave generated by the local signal generator 810 and the reception frequency signal received through the antenna receiver 720. In general, two signals having a sum and a difference of input frequencies of a mixing unit as a frequency are generated, and among these, only the signal having a difference of the input frequency as a frequency is amplified by the intermediate frequency amplifier 400.

Subsequently, the intermediate frequency amplifying unit 400 amplifies the intermediate frequency signal, and the intermediate frequency output terminal 830 does not immediately convert the high frequency band when the frequency of the high frequency band is converted into the low frequency band frequency. Allows conversion to other forms of frequency. The intermediate frequency amplifier 400 amplifies the intermediate frequency signal output from the intermediate frequency output terminal 830 to an appropriate level. In some cases, the voltage stabilizer may be further mounted on the output side of the intermediate frequency amplifier 400. It may be. In addition, the integrator or the averager 410 exchanges the intermediate frequency signal amplified by the intermediate frequency amplifier 400 at the front end of the signal determination unit 420, that is, at the output terminal 830 of the intermediate frequency amplifier 400. Integrate or average for an integral multiple of the power cycle to detect when the value is above or below a certain amount.

In addition, the signal determining unit 420 signals the intermediate frequency signal amplified by the intermediate frequency amplifying unit 400 to determine the presence and speed of an object, and in the resonator 500, the X-band oscillator. To secure a certain quality (Q) or more and to cover the circuit formed on the module substrate 110 for oscillation and frequency control.

In addition, the controller chip 300 is configured to control the overall operation of the motion detection module 100 based on the signal output from the signal determination unit 420. That is, according to the signal output from the signal determination unit 420 generates a control signal for driving the peripheral device to be applied to the associated peripheral device.

In the motion detection module 100, the motion detection operation is summarized as follows.

When the local signal generator 810 continuously oscillates a specific frequency of 10.525 GHz, and the 10.525 GHz transmission frequency signal oscillated by the local signal generator 810 through the antenna transmitter 710 is emitted into the air. In the standby state in which the object is not approached, the antenna receiver 720 receives the frequency emitted through the antenna transmitter 710 and passes the frequency mixer 820 to the intermediate frequency output terminal 830. Will flow into the. On the other hand, when the frequency of 10.525 GHz oscillated by the local signal generator 810 is launched into the air through the antenna transmitter 710, the object is captured by the operation sensor due to the approach of the object. The received frequency signal reflected and returned by the object is spaced apart from the transmission frequency transmitted from the existing antenna transmitter 710 to detect a motion change.

The transmission frequency signal and the reception frequency signal are mixed with each other through the frequency mixing unit 820 and then passed through the intermediate frequency output terminal 830. Through this series of processes, a low frequency voltage is calculated and the calculated The low frequency voltage is processed according to a command designated for the purpose of each sensor by the operation between the operation of the intermediate frequency processing stage and the embedded program so that the peripheral device can be finally operated through the controller chip 300.

In this case, the frequency mixer 820 generally uses a diode mixer. In terms of sensitivity, the frequency mixer 820 is excellent in performance of a mixer to which an active element such as the HEMT 450 is applied. However, in the case of noise caused by ripple on the power supply side, a mixer consisting of active elements is vulnerable, and thus a diode mixer, which is a passive device mixer without a power source, is frequently used. In general, diode mixers are made of antiparalleled diodes, which have a balanced structure, which minimizes LO feed-thru.

Since the above configuration and operation are general in general motion detection sensor technology, further detailed description thereof will be omitted.

Next, the antenna circuit structure of the motion detection module 100 according to the present invention will be described with reference to FIG. 3.

As shown in FIG. 3, the antenna 110 includes an antenna transmitter 710 having two antenna patches 715 and a feed line 725 at an upper end of the substrate 110, and two antenna patches 715 at a lower end of the substrate 110. And an antenna receiver 720 having a feed line 725. Conventionally, the antenna patch 715 is provided as a single antenna transmitting and receiving unit (710, 720), respectively, in the present invention to improve the frequency transmission and reception sensitivity by providing two left and right one.

In this case, it is preferable that the antenna transceivers 710 and 720 respectively include a filter 735 which is connected in series to a portion of the feed line 725 connected to both ends of the antenna patch 715. Do. This serves to filter the electromagnetic waves in the vicinity applied through the antenna transmitter 710 between the local signal generator 810 and the antenna transmitter 710. In addition, between the antenna receiver 720 and the frequency mixer 820, the transmission and reception sensitivity may be improved by filtering the electromagnetic waves applied through the antenna receiver 720.

Figure 4 is a circuit diagram showing the configuration and amplification circuit of the resonator 500 of the motion detection module substrate 110 according to the present invention, as shown, the center of one surface of the substrate 110, such as RC, RL, RLC circuit A resonator 500 including a resonant circuit composed of the resonator circuit is configured, and an amplification unit 400 is configured at the upper right side of the resonator. 3 illustrates an amplifier circuit constituting the amplifier 400. However, since this is the same as a general sensor amplification circuit, a detailed description thereof will be omitted.

Here, the amplifier 400 is mounted in the form of a circuit on the motion detection module substrate, responsible for the amplification and correction of the signal, conventionally mounted on the main board instead of the sensor board, but the motion detection module 100 ) Includes all these parts in one board.

As shown in FIG. 6, the present invention uses a HEMT (Heterojunction Field-Effect Transistors) device, which is an active device, in the configuration of the motion sensing module 100. The advantages of the HEMT 450 are easy to modulate. It has the advantage of high gain, high frequency operation and low noise figure compared to MESFET.

In addition, the local signal generator 810 oscillates using a dielectric resonator (DRO) because the X-band oscillator needs to secure a certain quality factor (Q).

A passive element consisting of a normal microstripline 430 for series feedback is connected to a gate (G: Gate) terminal of the HEMT 450 element, and a drain stage bias circuit including a resistor for a bias, a bypass capacitor, etc. The output stage matching circuit and the drain stage bias circuit section are connected to the drain (D :) drain, and a predetermined position extending from the drain stage enables transmission and reception of the outgoing signal. The transmission and reception antennas 710 and 720, which also serve as reception functions, are connected to each other. The amplifier 450 is preferably formed at + 60dB. At this time, it is a matter of course to form a power supply terminal for applying the operating power to each circuit portion.

Next, the completed configuration of the motion detection module 100 according to the present invention through the above-described circuit configuration and sensing process will be described with reference to FIG. 7.

First, a cavity 510 having a substantially rectangular shape covering the resonant circuit and a plurality of elements is provided on one side of the upper surface of the substrate 110. This is to adjust the frequency by using the dielectric resonator DRO. It is to be able to insert a screw to adjust the gap between the and.

Conventionally, although the circuit is covered with a can-shaped cavity made of a common metal, in the present invention, it is composed of a low noise block down converter (LNB) type using a dielectric resonator (DRO) and has a square shape. It was configured to lower the overall height of the motion detection module 100, and the cavity 510 is formed of a plastic material to significantly reduce the weight, and the inner surface is plated with chromium (Cr) to smoothly post-process to remove the diffuse reflection To significantly reduce noise and increase resonance efficiency.

The cavity 510 is chrome plated on the surface after forming the shape by plastic injection. In addition, it is preferable to further form a hole 515 for frequency tuning in one side of the cavity 510.

The amplifier 510 is spaced apart from one side lower end of the cavity 510, and the amplifier 400 includes an amplifier circuit and a signal correction circuit. In addition, the control chip 300 is mounted on one end of the module substrate 110, which is a side surface of the connection pin 350. That is, the control chip 300 is embodied in one chip shape so as to be easily mounted according to the layout circuit configured on the module substrate 110.

In general, the controller chip 300 may include an independent program and recognize the detected signal to store the oscillator and its holding time, which are its standard time generators, in a microcontroller that controls the lamp, and initializes the program when a malfunction occurs. And a reset unit for setting a time, a time setting unit for setting a holding time, and a sensor input unit for detecting a movement of a person or a vehicle. Since the configuration of the control unit chip 300 is the same as that of the control unit of the conventional microcomputer structure, illustration and identification number display thereof are omitted.

The microcontroller continuously checks the operation of the detection sensor even after the light is turned on. If there is no signal in the sensor input part, the microcontroller becomes the reverse counter at the preset time. If the sensor is detected during the reverse counter, the microcontroller maintains the set time again. The time is shown in the time setting section. If there is no signal in the sensor input unit again, it is counted backward at the set time and turned off by the relay output unit after the set time.

When controlling to turn off automatically because there is no movement, instead of lowering the illuminance directly to zero, the user staying in the room can recognize that the main light is off, step by step, for example, illuminance 5 By sequentially lowering the illuminance to 4, 3, and 2, the user may generate a motion again to allow the illuminance of the main light to be returned to its original state (for example, illuminance 5).

In the present invention, while the microcontroller, which is the control unit chip 300, is implemented as a simple circuit using a plurality of variable resistors and electric elements in order to improve module miniaturization and device simplicity in an embodiment implemented by existing complex circuits and multiple sensor arrangements, This is implemented in the shape of a One Chip.

Looking at the components of the control circuit chip 300 mounted on the module substrate circuit in detail as follows. 9 illustrates a circuit of a control unit chip according to the present invention.

First, the names of the main components of the circuit symbols and their roles will be briefly described.

Here, VR means a variable resistor, VR1 is a configuration for adjusting the sensitivity sensitivity, VR2 is connected to an external timer for the time adjustment, VR3 is a configuration for adjusting the external brightness.

CDS is an optical sensor for external brightness control, PTC is a temperature sensor for detecting circuit overheating to prevent sudden switching malfunctions, Amped-IF is an amplified IF (intermediate frequency output stage) in the amp part of the motion sensor, and VCC is a DC power supply. , Q is the external motion detection signal, ~ Q is the inversion signal of the Q signal. In addition, the pin numbers 1 to 16 illustrated refer to external pins of the control chip mounted.

Hereinafter, the configuration circuit operation of the control unit chip 300 having the above main configuration will be briefly described.

C is charged as soon as power is applied during initial driving, and at this time, VR1, VR2, and VR3 are assumed to be any appropriate values (100k to 2M).

In addition, when the signal of the motion sensor introduced through PTC through Amped-IF is higher than the voltage set in VR1, C is instantaneously discharged by the internal circuit. Then, the same voltage signal as VCC is applied to Q during the time of recharging C.

At this time, the charging of C can be set to a certain charging time according to the resistance value set in the VR2, and depending on the setting, it is preferable to set at least 5 seconds from the minimum 5 seconds depending on the capacity and the maximum value of the VR2. .

The signal applied to Q is stopped when C is fully charged by comparing the reference voltage and the voltage at which C is fully charged. Since the resistance of CDS varies depending on the ambient brightness, the voltage is connected to VR3 to change the voltage according to the brightness. Let's go. According to the resistance value and the amount of voltage change, in addition to the signal application condition of Q, whether the signal is applied according to the brightness is controlled.

The PTC has a resistance value depending on the ambient temperature, thereby partially controlling the connection of the amped-IF signal in order to avoid circuit malfunction due to overheating of the circuit or overheating of the ambient temperature.

In the circuit diagram, the peripheral circuit connected to pin 7 is a circuit that allows the signal of Q to smoothly change to the signal of ~ Q with a certain time.

As described above, the overall size of the motion detection module 100 is minimized by simplifying a single control chip 300 equipped with a control circuit that simplifies a conventional control logic circuit and other complicated configurations, and controls the circuit and control from an external environment. The device was protected to increase control stability. That is, the motion detection module 100 is implemented by using the control chip 300 that replaces the micom role with a minimum board size and module circuit configuration.
