Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the invention  
           [0002]    The present invention relates to telephone controlled vehicle intrusion sensor and report apparatus, in particular, the apparatus is operatable by calling from an wired phone or a wireless cellular phone to a wireless phone controlled in the vehicle to start the vehicle air conditioner and set up the vehicle alarm system on work, also the apparatus is capable of reporting the present state such as temperature of the vehicle etc. to the owner through the vehicle wireless phone.  
           [0003]    2. Description of the Prior Art  
           [0004]    There were several patents offered to inventions concerning to remote control of vehicles in Taiwan ROC. For example, “Remote Control System for Vehicle Air Conditioner” (95297). “Automatic Remote Control for Vehicle Indoor Temperature” (96299), and “Remote Control System for Preheating and Starting Automobile Engine”. In all these cited cases, they are commonly characterized in that the remote control device formed in compliance with FCC standards is used. However, such a remote control device has several shortcomings:  
           [0005]    1. Available control distance is only as short as 10˜50 yards that discourages intention of the owners to use.  
           [0006]    2. If it is desired to lengthen the controllable distance, power of the device must be increased which causes the device become bulky or cause radio interference.  
           [0007]    3. No report facility results in that the owner away from his/her vehicle is unable to be notified of the present vehicle state.  
           [0008]    In order to overcome the shortcomings inherent to the conventional technique described above, the present inventor has delved into this matter with a long time efforts and came to realization of the present invention.  
         SUMMARY OF THE INVENTION  
         [0009]    Therefore, the present invention is aimed to provide telephone controlled vehicle intrusion detection and report apparatus which is operatable by calling from an wired phone or a wireless cellular phone to a wireless phone control module in the vehicle to start the vehicle air conditioner and set up the vehicle alarm system to work, also the apparatus is made capable of reporting the present state, such as inside temperature of the vehicle etc., to the caller far apart from his/her vehicle through the wireless phone installed in the vehicle.  
           [0010]    To achieving the above mentioned objects, in the present invention, the vehicle intrusion sensor and electronic doorlock can be controlled remotely by the owner&#39;s cellular phone instead of carrying a string of individual remote controllers along with. In addition, the vehicle air conditioner can be started by an owner&#39;s calling to the vehicle phone via a wired phone or a cellular phone from far distance. Besides, the effective operational distance of the present invention covers a wide range and even functional in underground parking lots.  
           [0011]    For fuller understanding of the nature and objects of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0015]    [0015]FIG. 1 is a circuit block diagram of the present invention. It shows that the apparatus of the present invention comprises a power source  11  for supplying stable electrical power to the present invention; an acoustic decoder circuit  12  for decoding a multi-frequency control signal received, and sending the decoded signal to a MPU; a vehicle wireless phone  13  for receiving control signals from a wired phone or a cellular phone, and for transmitting an intrusion alarm or a return signal; a MPU  14  composing of a CPU, a RAM, a ROM, an output port, and an input port, the ROM is a program storage area wherein data treated by CPU and the RAM is outputted via the output port or read in via the input port; a voice circuit  15  for inputting a plurality of pre-recorded report voice combination from a microphone, and reporting to the owner via a speaker  5  or a vehicle wireless phone  13  according to classification made by the MPU  14  at appropriately predetermined delivery timing; an interface for output/input control  16  for sending a two-way information signal of the MPU  14  to a vehicle intrusion sensor circuit  2  and an air conditioner controller  3 ; a man to machine interface  17  for enabling the owner to input parameters for the present system with an input equipment. Meanwhile, the MPU  14  stays in waiting and watching state after being activated, as soon as the vehicle wireless phone  13  has received a phone call from the owner, the signal is decoded by the acoustic decoder circuit  12  and sent to the MPU  14  for identifying. If it is a valid signal to be true, then the signal enters the voice circuit  15  for selecting a relevant order which starts the engine by actuating an electric key through the interface  16 , at the same time the air conditioner  3  is set at a predetermined temperature. In case a vehicle intrusion sensor circuit  2  is not released from its watching duty according to a normal procedure during the engine is under energized state, a signal is sent to the MPU  14  from the acoustic decoder circuit  12  and the information is reported to the owner via the voice circuit  15  and the vehicle wireless phone  13 . The phone call signal received by the vehicle wireless phone  13  is decoded by the acoustic decoder circuit  12  before transmitting the signal to MPU for identifying. If the signals are judged to be false successively for more than three times, the MPU  14  disconnects the communication with the vehicle wireless phone  13  at once and reports to the owner via voice circuit  15 .  
         [0016]    In case the vehicle intrusion sensor circuit  2  receives an abnormal vehicle door signal or other alarm signals, the signals are transmitted to the MPU  14  through the interface  16  for judgement immediately, and the information is reported to the owner by the vehicle radio phone  13  via voice circuit  15  at once.  
         [0017]    In the present invention the input equipment to the man-machine interface  17  can be a wired or a wireless phone, or in voice control form for inputting related parameters, and the voice is outputted from the speaker  5  via voice circuit  15 .  
         [0018]    Meanwhile, in the present invention, a gear shift position detector circuit  18  is provided for sending an terminal signal to the output/input control interface  16  for detecting if the gear is shifted to P or N position in an automatic gear shift vehicle or to the neutral position in a manual gear shift vehicle so as to make sure if the vehicle is securely parked.  
         [0019]    [0019]FIG. 2 is a flow chart of operation of the present invention. The apparatus of the present invention is set up in waiting and watching state after being activated. As soon as the vehicle wireless phone has received a phone call from the owner, the signal is decoded by the acoustic decoder circuit and if it is identified to be correct, then the signal enters the voice circuit for selection of a relevant input which starts the engine by controlling an electric key through the output/input control interface, at the same time the air conditioner is set at a predetermined temperature. If the signal is judged to be false for more than three times, the communication with the vehicle wireless phone is disconnected at once and the owner gets an immediate report about this situation.  
         [0020]    [0020]FIG. 3 is a flow chart illustrating that the running of the program is interrupted upon sensing an abnormal signal from the vehicle door sensor. After interruption of the program, the present situation is immediately reported to the owner by the vehicle radio phone through the voice circuit.
