I horn can be used as an audible warning, but in the installation of the car, this cable must be routed from the car through the car's firewall to the engine room and connected to the horn. For smooth threading, the firewall must be connected to the original wiring hole or engine Cover opening wire hole

I can be expanded even when drilling holes in the firewall. In addition to increasing the number of installation workers i, the sealing is damaged due to reaming or drilling, so that radon or water can enter the car.

Although, in order to save installation time and avoid breaking the seal of the original firewall, this team can be designed as a wiring-free method. You only need to connect the wireless cable to the positive and negative ends of the battery to accept the control of the host, so as to avoid wiring. It can be designed as a radio transmission, and in order to avoid mutual interference between the wireless team and the anti-theft host, it must be designed with different frequencies and must have a considerable _ frequency difference so as not to interfere with each other, but in some countries only agree to a certain Band I or only a certain frequency can be used as wireless anti-theft. At this time, it cannot be overcome by using the same frequency. If the same frequency is used, the wireless router and the anti-theft host must operate at different times to avoid mutual interference. Disturb, but this again makes no '

Description of the invention (2) The function of the cable can not be immediately followed by the command of the host u The function of u is greatly reduced, which is its biggest disadvantage. In order to overcome the above-mentioned problems, the present invention is a technical bottleneck because there is a lot of noise on the wire that will cause the "electrical" wire to pass the password, and the high or low voltage will make the password a big distortion of 2 or 0. 11 It is currently to be overcome.

1238129 V. Description of the invention (5) '--- Sound. For the detailed circuit composition, please refer to the second figure. The main electromechanical input power enters through D 1 (reverse protection), and z R] = noise L 1, C 1 and C 2 are used as chirp waves, and ui is The voltage ^ C is reduced by R 1 and c 3 to supply the circuit to the circuit, and the voltage is set at a constant level. The external input control signal is filtered through R 4 and R 5 as A to Λ, and u is filtered by the input impedance and voltage divider C 8, and then input to C ρ υ thunder r η through R 6, The working circuit of the CPU must be 2 oscillating frequency. The input signal is digitally exhausted by the CPU to generate a specific frequency. For example, a square wave of 5 5 Κ Η Z can be used to represent i, and 60 KHZ can be used to represent 0. It can also be used. Signals at other frequencies are used as i 0, or a certain frequency is used as a basis (for example, 5 5KHZ), and the same wave width is used as the representative of the codes 1 and 0. The reason why different frequencies 5 are used to represent 1 or 0, or based on a certain frequency and different wave widths are used to represent work and 0, is to facilitate the signal modulation on the power line, and can be related to the noise of the power line. The difference is so that noise does not interfere with the password. The digital password is sent to the U 2 FET driving circuit (1 3) 'and at the same time this post code k is amplified so that there is enough current to drive the RLC oscillation circuit (14) composed of L 2, C, C5 and C6, r 3 and R 2 are impedance matching. The input digital password is converted into an RLC oscillating circuit (14) composed of l 2 and the like, and the digital signal is converted into an analog k number 'to the analog signal after R 2 is amplified again, so that There is enough electrical energy to be coupled to the secondary winding through the primary winding of the T 1 transformer.

After R 1 filtering, C 5 voltage, and c 1 vibration surplus, the code signal can be closely read and decoded. Then Q 3. When the required power line is installed, the same frequency cannot be sent at the same time. At this time, if there is a password, it can be used as a signal. The power supply c 1 and C wave provide voltage division and filtering, and the point, from the input 1 , C 1 (2 3 The original power cord is amplified with the code signal and transcoded to X 1. The correct Q 4 and Q sound will be transmitted. This letter is transmitted, and it is possible to avoid the need to make a password when the action is required. The CP number exists through the original transmission, and after being waved by the ZR 2 filter circuit, it is put into the power source 2, D), and the power is turned on. After that, the transmission is replaced by the number C 7, the signal is sent 5, and the method of Q is clear. In addition to drilling radio problems, sound. 1 or 0 υ know * within the transmission signal time ’Therefore, as long as the wireless speaker receives the signal by the power cord, it is very convenient to use. 1 for noise filtering, after D 1 is stepped down by U 1, the working voltage required by c is passed, and the analog signal on the comparison circuit (2 4) is obtained by L 2, D 3 and L 2 The password code is filtered out, and can be sent to the U 4 comparison circuit (2 digits, code 彳 § number, and then sent to
