Description

A door / starting control unit of a car using a portable wireless communication card, and the control method}

The present invention performs a bi-directional communication with the main unit installed inside the vehicle when a person holding a portable wireless communication card capable of bidirectional communication reaches within a certain distance of his vehicle, and automatically recognizes the owner according to the communication result. Open and close the door of the vehicle, and start communication or other operation only when all data match by re-communicating with the portable wireless communication card when starting the vehicle and operating various modes. It is possible to perform a unique operation without errors by eliminating interference from various electric and electronic devices or the same system installed in surrounding vehicles by communicating unique data bidirectionally between devices. A door / start control device and a method thereof.

In general, a remote control device for a vehicle that provides more convenience to the driver of the vehicle and allows the door and the start of the vehicle to be wirelessly developed to prevent theft has been developed and widely used.

As an example, Korean Patent No. 6095 (registered on August 22, 1990) proposed by the inventor of the present application includes a microcomputer that can control the opening and closing of a vehicle, starting power on and off, and theft alarm. By installing the built-in main control unit, only the driver who has a remote control whose password is the same as the password stored in this main control unit can turn on / off the door opening and starting power of the car, and detects an intruder who does not carry the remote control. It has been proposed to sound an alarm or to defeat intruders.

The remote control apparatus of the vehicle as described above not only hassle that the driver has to manually operate the buttons installed on the remote controller when the door is opened or closed, and there are a plurality of vehicles in the vicinity, or various electronic devices around the vehicle. There is a problem that frequently causes malfunction due to the interference of electromagnetic waves generated from the.

In addition, the inventor of the present application does not use the car key as in the Republic of Korea Patent No. 7176 (Registration date September 19, 1991) in order to supplement the above-mentioned problem of the Republic of Korea Patent No. 6095 and to make the use more convenient. Simply carry the remote control without getting close to the car and the door lock will unlock automatically, allowing the user to open the door and enter the car, and the door lock will automatically unlock when the user is away from the car with the remote control. It is proposed that the locking operation, and the door lock device to operate as the burglar alarm after the locking operation.

However, the Republic of Korea Patent No. 7176 is a long-wave transmitter and receiver for transmitting and receiving long-wave (LF) of 100KHz band when a plurality of vehicles and a number of automatic call out remote control is manufactured and shipped, ultra-high frequency (VHF) Transmitter / receiver uses the same frequency band specified on the designated frequency allocation for the vehicle defined in the Radio Frequency Management Act. This causes the long-wave signal to be modulated (no unique data) and transmitted to the automatic remote radio controller.

Therefore, when accessing the automatic remote radio controller to TVs, computer monitors, electronic copiers, three-wavelength fluorescent lamps, other home appliances, and electric and electronic devices that generate strong radio waves in the 100KHz or near frequency bands The circuit continued to operate, causing the card's internal mercury battery to drain, making it unsuitable for practical use.

When multiple autonomous radio remote controllers approach a vehicle, all autonomous radio remote controllers with long-wave sensitivity ranges operate simultaneously, allowing ultra-high frequency (VHF) transmitters in each autonomous radio remote controller to transmit unique data simultaneously. As a result, the vehicle will not be able to read the specified unique data because of the interference caused by the same frequency.

In other words, when two or more autonomous wireless remote controllers are approaching one vehicle at the same time or one or more autonomous wireless remote controllers are approaching two or more vehicles, the one-way unique data transmission method may operate normally due to the same frequency interference. There is a problem that can not be.

In addition, the card method developed so that two-way communication can be performed in a non-power source in other fields to date, the sensing distance is up to 30 cm under the same conditions, and can not achieve the above purpose, bi-directional power supply (using ordinary batteries) method When the communication card is used, the card reception method uses the ultra-low frequency (VHF band) reception method instead of the ultra low-power long-wave (LF) reception method. Therefore, current consumption cannot be minimized due to the reference bias current of the circuit in standby mode. Even if the intermittent intermittent operation without operating the microwave transmitter in the card to reduce the current, the instantaneous current consumption during operation consumes several mA, so the mercury battery with a capacity of 200 mA or less is used within 10 days. Is impossible.

In addition, since the continuous transmission / reception circuit of VHF bands must use a large-size general battery (based on 1.2A alkaline batteries), the standby current must be at least 2mA or more (frequency than the long-wave 100KHz circuit) to operate the ultra-high frequency receiver. Because the band is high, the bias voltage is high when the circuit bias voltage is stabilized and the frequency is stabilized.) As the battery is consumed, the battery life is up to about 1 month, which causes frequent user changes and frequent breakdowns. Since the battery is large, the volume of the card becomes almost the same as that of a general vehicle remote control, and the product becomes heavy, which makes it impossible to carry it in a wallet or a pocket.

The present invention is to solve the above problems, and comprises a portable wireless communication card, a main unit and a remote control transmitter to transmit a long wave (LF band) including a synchronization signal periodically from the main unit installed in the vehicle and portable wireless communication When the owner of the card approaches his vehicle (within 1 ~ 5m distance), the microprocessor in the card is operated by using the long wave signal, and the wireless card generates the periodic code by random (RANDOM) method. By transmitting the unique data stored in the wireless card in any channel, it was prevented from being repeatedly transmitted in the same period.

In addition to the unique data, a new ALLFREE code was generated and transmitted by the periodic code, the mode code, and the checksum bit, and the main device detected the unique data from the received signal and stored it in the memory. Compared with the ID (primary ID check), if they match each other, the cycle code is converted into 16-bit long wave ID and retransmitted.

If the second ID is identical with each other, the high frequency wave (VHF band) including the ID signal and the door release signal is transmitted again to receive the high frequency wave from the main unit, and then compared with the unique data stored in the memory chip in the main unit. If they match each other (3rd ID verification), the vehicle door is released to eliminate interference by the same frequency, and the reliability is improved by repeatedly performing ID verification between the portable wireless communication card and the main device.

In addition, if the driver opens and lowers the door after driving and moves away from the vehicle for a certain distance (about 5m), the ID communication with the wireless card is cut off and the door is automatically locked and returned to the initial state. To open and close the door automatically.

If the person holding the portable wireless communication card presses the start button of the remote control transmitter installed in the vehicle, the microprocessor operates to transmit the start signal to the microwave (VHF), and receives the data from the main device to receive the unique data from the portable wireless communication card. If the match is found, the vehicle is started and if it is not matched, the start signal is ignored so that only the owner of the vehicle can start the vehicle, thereby increasing the effectiveness of anti-theft.

In addition, the main unit periodically transmits a long wave (LF band) including a synchronization signal with low current consumption, receives the long wave from the portable wireless communication card, checks the long wave transmitter, and then operates a microwave transmitter. The current is minimized, and the long-wave receiver in the portable wireless communication card is a continuous operation circuit in the reception standby state that can receive data from the main device at all times, so it transmits data compared to existing equipment using ultra-high frequency band that transmits data intermittently. The reception speed is fast and it is configured to be considerably superior in accuracy.

The present invention provides a system for controlling a door lock device, a start device, and an alarm device of a vehicle by using wireless communication, wherein the first long wave including a synchronization signal is periodically installed inside the vehicle, and the first microwave wave is received. Verify the unique data and the all-free code, and transmit the second long wave based on the result, receive the second microwave, verify the unique data and the all-free code, release the door lock according to the result, and then the third microwave. Receives and analyzes a main device for controlling a starter, an alarm device, and the like, and a first long wave including a synchronization signal transmitted from the main device, and extracts and compares an arbitrary period code as a random function. Analyzes and transmits the first ultra-short wave containing the unique data and the all-free code according to the result, and receives the second long wave to compare the long-wave ID detection and the period code. In other words, according to the result, the portable wireless communication card transmits the all-free code to the main device and enters the sleep mode, and the third microwave which is installed inside the vehicle and contains the operation signal according to a plurality of button operations is sent to the main device. A remote control transmitter is provided, and a door switch unit for transmitting an open / close signal is connected to an input side of the main device according to a door open / close state of the vehicle, and an output side of the main device controls a door lock device, a start device, and an alarm device. The vehicle control unit is characterized by being connected.

First, the essential requirements for the contactless two-way wireless data transmission method using a portable wireless communication card is as follows.

First, the detection distance between the vehicle and the owner of the wireless card must be at least 1 to 5m. When two or more cards with different data are approaching one vehicle at the same time (or two or more parked vehicles) When people with one or more cards in the vehicle approach simultaneously, the vehicle receiver must be able to read the data correctly even when interference from the same frequency occurs.

Secondly, when several people with wireless cards ride with one owner in one vehicle, there should be no data interference from the cards they carry. If different vehicles choose different frequencies to avoid co-frequency interference, this is theoretically possible, but the frequencies used for vehicle door controls and alarms around the world are allotted, making the choice of many different frequency bands virtually impossible.

Thirdly, the battery using the wireless card should have almost no trouble in terms of convenience. Therefore, frequent battery replacement circuits should be suppressed, and consequently, the current consumption of the wireless card circuit should be minimized in order to prolong the battery life. It is worth it and can be used on a real vehicle.

The present invention satisfies all of the above, and will be described in detail below with reference to the accompanying drawings, the configuration and operation of the present invention.

1 is a block diagram of a door / start control device for a vehicle using a portable wireless communication card according to the present invention, which is installed inside a vehicle and periodically includes first and second long waves LF1 and LF2 including a synchronization signal and unique data. ), And receives the first and second ultra-high frequency (VHF1) (VHF2) transmitted from the portable wireless communication card 400, reads various unique data, and outputs a predetermined control signal when it matches the stored data.

In addition, the remote control transmitter 300 is installed inside the vehicle and transmits an operation signal of the third microwave VHF3 to the main device 200 when the driver operates the start button, the mode button, and the forced alarm button. Receiving the first and second long waves LF1 and LF2 including the synchronization signal and the unique data transmitted from the 200, the first and second ultra-high frequencies VHF1 including the first and second unique data and the door release signal. A portable wireless communication card 400 for transmitting VHF2 is provided.

In addition, the door switch unit 210 for transmitting the opening and closing signal of the door to the main device 200 is connected to the input terminal of the main device 200, the portable wireless communication card 400 and the main device 200 bi-directional data communication By operating through a process of mutually confirming that the owner of the vehicle through the operation is not possible without a portable wireless communication card corresponding to the vehicle.

When explaining the operation concept by the block diagram shown in Figure 1 of the door / start control device of a vehicle using a portable wireless communication card according to the present invention made as follows.

First, the main device 200 installed in the vehicle periodically transmits the first long wave LF1 including the synchronization signal at a constant cycle, and in this state, the owner of the portable wireless communication card 400 approaches the vehicle. Synchronized by the first long wave (LF1) to generate a periodic code in a random (RANDOM) manner to load unique data stored in any one of a plurality of channels and transmit it to the first ultra-high frequency (VHF1). do.

Here, in addition to the unique data carried on the first microwave VHF1 transmitted from the portable wireless communication card 400, a new all-free code is generated every time by the period code, the mode code, and the checksum bit. The repetitive transmission as a period was prevented.

The main device 200 receives the first ultra-high frequency (VHF1) transmitted from the portable wireless communication card 400, detects the unique data, compares the unique data stored in the memory (primary ID check), and if there is a mutual match The code is converted into a second long wave LF2 including a 16-bit long wave ID and retransmitted. At this time, the portable radio communication card 400 compares the long wave ID carried on the second long wave LF2 (confirms the secondary ID). ), If they coincide with each other, the second microwave VHF2 including the ID signal and the door release signal is transmitted again.

The main device 200 receives the second microwave (VHF2) signal transmitted from the portable wireless communication card 400 and compares it with the unique data stored in the memory in the main device 200 again (confirms the third ID). If they coincide with each other, the vehicle door is released.

Therefore, the main device 200 and the portable wireless communication card 400 repeatedly check the unique data three times by bidirectional communication, thereby improving reliability and eliminating interference by the same frequency.

When the start button of the remote control transmitter 300 installed inside the vehicle in a state where the door is released by the person holding the portable wireless communication card 400, the start signal as the third ultra-high frequency (VHF3) main device 200 And the main device 200 receives the third microwave VHF3 transmitted from the remote control transmitter 300, checks the ID with the portable wireless communication card 400, and starts the vehicle if the ID matches. If it does not match, the start signal is ignored so that the start does not occur without the portable wireless communication card corresponding to the vehicle.

When the mode button of the remote control transmitter 300 is operated, the system may be normally operated, or may be operated with an existing metal key. It is possible to operate this vehicle without).

On the other hand, after the vehicle is completed, when the driver opens the door and moves away from the vehicle by a certain distance (about 5 m) or more, the door is automatically locked as the ID communication between the portable wireless communication card 400 and the main device 200 is lost. By returning to the initial state, the door of the vehicle can be opened and closed automatically without the existing metal key.

That is, all of these processes are operated through a process of mutually confirming that the vehicle is the owner of the vehicle through bidirectional data communication between the portable wireless communication card 400 and the main device 200. Therefore, the portable wireless communication card 400 corresponding to the vehicle is operated. It is impossible to operate without it.

In order to achieve the above purpose, it is durable, easy to install in the vehicle, and the main component circuit is composed of ultra small microchip and hybrid chip (HYBRID CHIP), so there is almost no circuit error and can be miniaturized, especially portable in wallet or pocket The wireless communication card 400 is designed to be ultra light in weight and small in size, and to have a long service life.

In addition, it can be replaced with the device of the present invention at the cost of purchasing the existing vehicle alarm, characterized by economical, especially when the vehicle is manufactured by eliminating the key box and attaching the device of the present invention does not require the use of a metal key vehicle In addition to reducing theft accidents, the driver can secure a large space in the driver's seat.

4 is a detailed block diagram of a remote control transmitter 300 installed in a vehicle according to the present invention, and includes a start button 311, a mode button 312, a forced alarm button 313, and an automatic start switching button 314. The main device 200 transmits an operation signal by a third microprocessor 315 for outputting a control signal proportional to the operation of each button 311 to 314 and a control signal of the third microprocessor 315. A second microwave transmitter 320 which transmits a third microwave VHF3 to the second microwave transmitter 320, a start lamp 316 which displays an operating state and an automatic or manual operating state under the control of the third microprocessor 315; The mode lamp 317 is configured.

As described above, the operation process will be described in more detail with reference to the detailed block diagrams shown in FIGS. 2 to 4 as follows.

First, the long wave transmitter 240 is controlled by the control of the first microprocessor 201 of the main device 200 to periodically generate the first long wave LF1 of 100 Hz including a synchronization signal. LF1 radiates into space through the long wave transmission antenna 241. In this state, the portable wireless communication card 400 approaches the first long wave LF1 transmitted from the long wave transmission antenna 241 of the main apparatus 200 by approaching within 1 to 5 m from the vehicle. When the receiver 420 receives the signal, the long wave receiver 420 is synchronized with the first long wave LF1 to turn on the circuit of the portable wireless communication card 400 using the received signal energy.

Therefore, when the first long-wave signal LF1 is received, the second microprocessor 412 in the portable wireless communication card 400 controls the first microwave transmitter 430 to generate a period code in a random manner to generate a random code among a plurality of channels. The first microwave VHF1 is transmitted by loading the unique data stored in the channel of the channel, and the first microwave VHF1 is received by the microwave receiver 250 through the microwave transmitting antenna 251 of the main device 200. As a result, it is stabilized and standardized and transmitted to the first microprocessor 201.

The main device 200 receives the first ultra-high frequency (VHF1) transmitted from the portable wireless communication card 400, detects the unique data, compares the unique data stored in the memory (primary ID check), and if there is a long wave, Transmitter 240 converts the period code into a 16-bit long wave ID to retransmit the second long wave LF2 through the long wave transmission antenna 241, and the second long wave LF2 is a portable wireless communication card. When received by the long-wave receiver 420 in (400) and then stabilized and shaped to be transmitted to the second microprocessor 412 by comparing the long-wave ID carried in the second long-wave LF2 (secondary ID check) The first microwave transmitter 430 is controlled to transmit the second microwave VHF2 including the ID signal and the door release signal to the main device 200 again.

The first microprocessor 201 of the main device 200 receives the second microwave VHF2 transmitted from the portable wireless communication card 400 through the microwave receiving antenna 251 and the microwave receiver 250. When the received unique data is compared with the unique data stored in the Y pyrom 203 (confirmation of the 3rd ID) and mutually coincides with each other, the door control circuit 610 of the vehicle control unit 600 is controlled to release the door of the vehicle. do.

On the other hand, the first microprocessor 201 recognizes the driver through continuous data communication between the portable wireless communication card 400 and the main device 200, but the driver gets out of the vehicle and closes the door. 2) or more away, the second microwave (VHF2) signal transmitted from the portable wireless communication card 400 disappears and the first microprocessor 201 because the microwave transmission antenna 251 of the main device 200 cannot receive the unique data. The controller controls the door control circuit 610 of the vehicle control unit 600 to lock the vehicle door and return to the initialization state.

Here, the door switch unit 231 accurately detects the operation of the first microprocessor 201 by detecting whether the door of the vehicle is opened or closed when the main device 200 is initialized or during operation.

On the other hand, the lock of the vehicle door is released by the normal operation of the portable wireless communication card 400 to allow the driver to operate the start button 311 installed in the remote control transmitter 300 of FIG. 4 installed in the vehicle. The third microprocessor 315 controls the second microwave transmitter 320 to transmit the third microwave VHF3, which is unique data including a start signal, to the main device 200, and the third microwave VHF3. ) Is received by the microwave receiver 250 through the microwave receiving antenna 251 of the main device 200 to be stabilized and shaped and transmitted to the first microprocessor 201.

At this time, when the start signal is input from the remote control transmitter 300, the first microprocessor 201 continuously checks the ID while continuously communicating with the portable wireless communication card 400, and the identified ID is the main device 200. If it matches the ID stored in the driving control circuit 620 of the vehicle control unit 600 to start the vehicle, and if it does not match by ignoring the start signal without the portable wireless communication card 400 corresponding to the vehicle It does not start.

When the driver receives a mode signal to the main device 200 by operating the mode button 312, which is the remote control transmitter 300 of FIG. 4 installed in the vehicle, the operation of the system is completely stopped, and Being able to operate as a metal key enables the driver other than the owner, such as in a parking lot, to operate without the portable wireless communication card 400, and when the mode signal is received (OFF) again, the system will operate normally. When the start signal and the mode signal input, it operates after confirming the owner through the unique data communication with the portable wireless communication card (400).

In addition, when the start button 311 and the mode button 312 which are the remote control transmitter 300 are operated, the start lamp 316 and the mode lamp 317 are turned on under the control of the third microprocessor 315 to control the operation state. Forced alarm button 313 can operate the alarm bell in an emergency, and automatic start changeover switch 314 to select to start or start the vehicle automatically or manually.

All the above operations can be confirmed by the unique data through the two-way data communication between the portable wireless communication card 400 and the main device 200, so if a third party forcibly opens the door and starts with the existing metal key, Not to be caught, of course, will drive the forced alarm control circuit 640 to transmit the alarm sound.

In this case, the portable radio communication card 400 is configured to receive and transmit a high frequency wave (VHF) or an ultra high frequency wave (UHF) instead of the long wave receiver 420 and the long wave transmitter 240 of the main device 200. The battery 414 of the wireless communication card 400 can be extended, and the transmission speed can be faster than the transmission and reception means of the long wave (LF) band, and the sensing distance can be extended to 100 m or more.

In addition, when a separate long wave (LF) inductive reception antenna and an alarm function are additionally installed in the portable wireless communication card 400, the output state of electromagnetic waves generated from a TV, a monitor, and other home appliances can be grasped. That is, when the portable wireless communication card 400 approaches within the electromagnetic harmfulness detection distance, an alarm in the card may be automatically notified to expose the harmful electromagnetic waves, thereby preventing the exposure of harmful electromagnetic waves to the human body in advance.

5 is a system timing diagram of a door / start control apparatus for a vehicle using a portable wireless communication card according to the present invention. The initialization condition of the system is that the door of the vehicle should be closed as shown in (a), and the main device 200 ), Periodically, the first long wave LF1, which is the same as (b), should be transmitted.

In such a state, when the portable wireless communication card 400 is within a certain distance from the vehicle, as shown in (c), the first long wave LF1 is received to mutually check the unique data, and when the portable wireless communication card 400 is identical, e) Releases the door of the vehicle by sending the door release signal as shown in the figure.If the door of the vehicle is not opened within a certain time (4 seconds), the card is checked for the existence of the card. Lock the door and return to the initial state.

At this time, if the door is opened within 4 seconds while maintaining the release state, the door switch unit 210 detects that the door is closed, and when the start button is operated in the state where the portable wireless communication card 400 is present (t _{2 of} f) When the door is automatically locked, the system starts to operate normally from the moment the door is opened (t _{1 of} f degree) and receives the operation of the start and mode buttons from the remote control transmitter 300 and when the system is reset. Receive until.

Therefore, when each button is operated from the remote control transmitter 300, the main device 200 transmits the first long wave LF1 including the synchronization signal, checks the unique data of the portable wireless communication card 400, and then matches the normal data. If the ignition is turned off after driving the vehicle (f ₃ t ₃ ), after checking the portable wireless communication card 400, the door is automatically locked and the driver gets off and closes the door (t ₄ 4 f). If the unique data does not match after detecting the unique data of the wireless communication card 400, the door is locked and all circuits are reset, and the main device 200 periodically sends a synchronization signal again.

6, 7A and 7B will be described in detail the operation process of the main device 200 and the vehicle control unit 600 as follows.

First, the constant voltage circuit 206 is a circuit for supplying power required for the main device 200 by receiving + 12V power from a vehicle. The output voltage is + 12V (Vcc) for a vehicle, and this power supply is a coil L1. The + 12V from which the AC component is removed through the constant voltage device IC6 is outputted to supply the driving power to the main device 200 and the remote control transmitter 300.

The oscillation circuit of the first microprocessor 201, which is the main device 200, is a system using a capacitor C8, C9 and a crystal oscillator X1. Is supplied with the operating power by the constant voltage circuit 206.

In addition, the first microprocessor 201 operated by the above power source transmits a synchronous signal to the long wave transmitter 240 shown in FIG. 7A through the RB3 port, which is switched to the fast switching transistors of Q16 and Q17. After the LC oscillation circuit (Colpitts oscillation) consisting of Q18, L3, C25, voltage division biased to resistors R27 (R28), amplified through a Darlington connection consisting of transistors Q19 (Q20) and then long-wave The output transformer L2 converts the first and second long waves LF1 and LF2 into the space through the long wave transmission antenna 241 serving as a coil antenna.

As described above, the first and second long wave waves LF1 and LF2 transmitted from the main device 200 communicate with the portable wireless communication card 400 shown in FIGS. 4 and 8. The first and second microwaves VHF1 and VHF2 are transmitted from the communication card 400 to the main device 200. The first and second microwaves VHF1 and VHF2 are microwaves of the main device 200. In the receiver 250.

That is, the first and second microwaves VHF1 and VHF2 transmitted from the portable wireless communication card 400 and the third microwave VHF3 transmitted from the remote control transmitter 300 are as shown in FIG. 7B. Received by the signal 251, the first stage amplification through the coupling capacitor (C30) to the transistor (Q21), and then tuned to the capacitor (C34) and coil (L4), and then transistor (Q22), coil (L5), capacitor Detection at C37, amplification and waveform shaping by the operational amplifier IC8 IC8, and then input to the RB0 port of the first microprocessor 201. FIG.

Here, the long-wave transmitter 240 and the microwave receiver 250 are designed to hybridize each chip to stabilize the circuit by reducing the current consumption and malfunctioning.

Next, the detailed operation process of the vehicle control unit 600 shown in FIG. 6 will be described. First, when an abnormal operation such as a door is opened without checking the unique data with the portable wireless communication card 400 or when the remote control unit 300 is forced from the remote control transmitter 300. When the signal of the alarm button 313 is input through the microwave receiver 250, a "low" signal is outputted through the RA3 port of the first microprocessor 201, and the signal of the transistor of the forced alarm control circuit 640 ( Q13) (Q14) is a high-speed switching and amplified by a fixed biased transistor (Q15) to operate the alarm bell through the speaker 204, while detecting the battery power and the voltage below the specified voltage through the voltage monitoring circuit 205 The alarm bell is activated and can be initialized by pressing the reset button 202 connected to the first microprocessor 201 to forcibly stop the alarm bell. .

At the same time, when operating the forced alarm button 313 of the remote control transmitter 300, the "low" and "high" signals are repeatedly output to the RB4 port of the first microprocessor 201, and this signal is a differential lighting circuit. The inverter Q7 of 630 inverts the transistor Q6 to turn on and off, and as a result, the + 12V power is periodically supplied to the relay RY3 as a result. In-lamp LP1 (LP2) will flash to inform the driver or people around him. Here, the capacitor C3 and the diode D8 are circuits for stabilizing the relay RY3.

In addition, the door switch unit 210 checks the opening / closing state of the door. If the state of the door is open, the jump switch (“low”) is input to the RB1 port of the first microprocessor 201 and “high” is input if the door is closed. JP4) is a circuit intended to be utilized in the operation of the system by jumping.

In addition, the door control circuit 610 is controlled through a door lock / release signal output through the RB5 port of the first microprocessor 201, and the lock signal and the release signal are inverted by using the multivibrator 611. Designed to reverse the operation of the two relays (RY1) and (RY2). If the output of the RB5 port is "low", transistor Q5 is turned on, and + 12V power is applied to relay RY2 to release the door. When the output is "high", the transistor Q4 is turned on to apply the relay RY1 + 12V power to lock the door.

The start control circuit 620 is controlled by the ACC and start signals output through the RB6 port and the RB7 port of the first microprocessor 201, and the ACC signal is transmitted through the RB6 port by a program input at the start-up of the vehicle. Low ", and this signal is inverted to" high "by Q9, causing transistor Q8 to turn on to apply a + 12V power supply to relay RY4 to keep the ACC output on.

At the same time, the start signal outputted "low" through the RB7 port of the first microprocessor 201 is inverted to "high" state by Q11, thereby turning on the transistor Q10 to supply a + 12V power supply to the relay RY5. By applying Vcc, Vcc is supplied as a start signal for about 2 seconds to start the vehicle, and then the output of the RB7 port is changed to "high" to supply Vcc to the ignition coil IG2.

8 is a detailed circuit diagram of a portable wireless communication card according to the present invention, which includes a processing unit 412 including a second microprocessor 412, an emergency transmission button 413, a battery 414, a long wave receiver 420, It consists of one ultra-short wave transmitter 430.

That is, while the power supply of the Vcc of the long wave receiver 420 passes through Q8, it supplies power to the long wave receiver 420 to maintain the long wave reception standby mode, and then receives a synchronization signal from the main device 200 through the reception antenna 421. Ultrashort amplification as the transistor Q13 via the coupling capacitor C33 of the lower surface wave receiver 420, and then tuned to the transistor Q12, the coil L5, and the capacitor C29, and the coupling capacitor C28. Through the transistor Q11, the second amplification and the diode D8 are detected, and then the transistor Q10 is again amplified by the transistor Q10 to provide a synchronization signal to the second microprocessor 412. The synchronization signal causes the transistor Q1. By turning on, the power of the battery 414 turns on the light emitting diode D4 while supplying driving power to the second microprocessor 412 to operate the portable wireless communication card 400.

This is because the second microprocessor 412 of the portable wireless communication card 400 is normally kept in standby mode, and the second microprocessor 412 is normally operated only after receiving the first long-wave signal LF1 from the main device 200. Minimize the current consumption of the portable wireless communication card 400 to maximize the replacement cycle of the battery 414, by operating the second microprocessor 412 by using a single synchronization signal and then inputted by a program By outputting a "high" signal through the RB0 port until the end of the operation, the battery 414 is continuously supplied through Q2.

On the other hand, the output of the transistor Q11 of the long-wave receiver 420 is detected by the diode D7 by detection, amplified by the transistor Q9 and input through the RA1 port of the second microprocessor 412 so that the second microprocessor The data is compared with the data stored in the data rom 412 in 412.

At this time, if the compared data is matched, the transmission signal TX is switched to "low" through the RA2 port. The Q6 of the first microwave transmitter 430 is turned on to supply power to the first microwave transmitter 430, and at the same time, the long wave. Since the unique power is transmitted through the RA0 port of the second microprocessor 412 after the driving power of the receiver 420 is turned off, power consumption may be reduced due to the alternating operation of the long wave receiver 420 and the first microwave transmitter 430. Minimized.

Therefore, the intrinsic data of the second microprocessor 412 applied to the first microwave transmitter 430 is an oscillation circuit composed of a transistor Q4, a coil L2, and a capacitor C12 of the first microwave transmitter 430. Oscillates the first and second ultra-high frequency (VHF1) (VHF2) through the Fitz oscillation, and is amplified by the transistor (Q5) through the coupling capacitor (C17) and sent out through the coil antenna (L4), this signal is the main It is received by the microwave receiving antenna 251 of the device 200.

Here, the long wave receiver 420 and the first microwave transmitter 430 are each composed of a hybrid chip, which is designed to minimize the size of the portable wireless communication card 400 because the current consumption is very small and the size is small.

9 is a detailed circuit diagram of a remote control transmitter according to the present invention, including a start button 311, a mode button 312, a forced alarm button 313, an automatic start switching switch 314, a third microprocessor 315, And a battery 318 and a second microwave transmitter 320.

In other words, when the start button 311 is operated, the transistor Q1 is turned on through the diode D3 to supply power to the third microprocessor 315 to the RA2 port. A low " signal is input to recognize the start-up signal, thereby turning on the light emitting diode 316 through the RB1 port and outputting transmission data to the second microwave transmitter 320 through the RB0 port.

In addition, when the mode button 312 is operated, the third microprocessor 315 receives the "low" signal through the RA1 port through the diode D4 to turn on the light emitting diode 317 through the RB2 port, and at the same time, RB0. The transmission data is output to the second microwave transmitter 320 through the port.

When the forced alarm button 313 is operated, the third microprocessor 315 is operated through the diode D5 to output the transmission data to the second microwave transmitter 320 through the RB0 port. ) Is a switch that can be used to automatically start / start the system is operated by pressing the mode button 312 for 2 seconds or more.

Therefore, when the transmission data is input to the second microwave transmitter 320 during the operation of the start button 311, the mode button 312, and the forced alarm button 313, the transistor Q4, the coil L2, and the capacitor C12 are operated. The third oscillation circuit VHF3 is oscillated through the configured oscillation circuit (Colpitts oscillation), amplified by the transistor Q5 through the coupling capacitor C17, and transmitted through the coil antenna L4. It is received by the microwave receiving antenna 251 of (200). The second microwave transmitter 320 is designed to stabilize the circuit by using a hybrid chip, which consumes very little current and reduces malfunction.

And transmit to the second long wave (LF2) (step 106), and if the received ID does not match the ID stored in the main device 200, the controller returns to the initialization state to send the synchronization signal again after a slight delay. 1 The test procedure (L2) is executed.

If it is determined that the second microwave VHF2 is received from the portable wireless communication card 400 within the designated time after executing the first verification process L2 (step 107), the unique data and the all-free code are verified (step 108).
