Embodiment 1

[0047] The contact device of the present embodiment is used for the hindered person of problem parking to communicate with the car owner, and the contact device of the present embodiment includes being arranged in the car: a central processing unit (CPU) 2, a central processing unit (CPU) 2 connected to the central processing unit 2 The customer's starting unit 1 at the start signal input end, a radio communication module 3 connected to the communication end of the central processor 2, a group of video and audio communication units 4 connected to the multimedia signal input end of the central processor 2.

[0048]The guest starting unit 1 is an inductive starting circuit with an infrared sensor as a starting component. The infrared sensor senses an infrared source, such as a human body, to instruct the inductive starting circuit to work. In this embodiment, there are four infrared sensors arranged around the car.

[0049] In this embodiment, the video and audio communication u...

Embodiment 2

[0053] Except being able to be used for the communication of problem parking, the communication method and the communication device of the present utility model can also be used for communication between the visitor and the house owner. In this embodiment, the communication device is set on the gate of the house owner.

[0054] The customer's starting unit in the customer's starting unit 1 is arranged on the outside top of the door frame. When a visitor stands at the door and calls the door, the process for the visitor to contact the house owner is: when the sensor in the guest activation unit 1 arranged on the gate senses the arrival of the visitor, it sends an induction signal to make the guest activation unit 1 The output end outputs the start signal to the start signal input end of the central processor central processor 2; as soon as the central processor 2 receives the start signal, it turns on the radio communication module 3 and calls the master receiving / sending devic...

Abstract

The invention relates to a connection method and its device, in the purpose of providing a instant connection method and the device between the interfered people and the vehicle owner in the parking problem or between the visitor and the house-owner. The invention uses a object started unit to input a starting signal to said central processor according to the set started pattern; the multimedia signal processing end of said central processor receives video and / or audio signal; when said central processor has received the starting signal, starting the radio communication module group to send host calling; after the host calling is connected, said central processor converts the video and / or audio signal input by said video and / or audio connection unit to the signal used by radio communication system; the radio communication module group connected to the central processor transmits said converted signal to the host receiving / transmitting device; the host receiving / transmitting device sends the feedback signal to the object via said radio communication system.

Description

technical field [0001] The invention relates to a communication method and a communication device. In particular, the utility model relates to a communication method and a communication device mainly aimed at the communication between the obstructed person and the owner of the vehicle or between the visitor and the owner of the parking problem. Background technique [0002] Existing automobile safety devices are mainly used for anti-theft. [0003] Chinese patent application 03156944 discloses a car anti-theft alarm that utilizes a radio communication system to transmit images captured by visible light and / or infrared imaging devices, and a system that dynamically monitors the situation of the car itself through the anti-theft sensor to monitor thieves or The saboteur attempts to destroy, enter or has entered the vehicle, turns on the camera and camera devices installed inside and outside the car, and captures images; and transmits images and various information to the remo...
