In this way, the car search system can quickly find a parking place for the car, which has industrial use value. [Previous technology] Cars are an indispensable means of transportation in daily life, especially when the rapid development of industry and commerce makes remote transportation more frequent, the number of cars is increasing day by day. In contrast, with regard to parking issues, various types The number of car parking spaces has also increased, especially in places such as airports, stations, supermarkets, hypermarkets, etc. In order to facilitate parking, most of them also have parking spaces that can accommodate a large number of vehicles. The above large-scale parking lot may also cause some inconveniences for people who want to drive fast. For example, when a vehicle is parked in a large parking lot, it is sometimes not easy to find its parking position correctly and quickly, and when the parking time is If it is too long, when the user forgets the parking position, or if the user gives the car key to a different driver, and needs to find the correct vehicle in the large parking space, it will cause trouble. Although traditional sound and light devices are also installed on vehicles, such as electronic anti-theft locks installed on ordinary vehicles, when the remote control is pressed, the vehicle will display sound and light, but this device is only used in small spaces. The small parking lot is effective, it is not practical to listen to the aforementioned large parking space or large parking lot, and it still causes the problem of car search _ [summary of the invention] In view of the above reasons, the present invention provides a car search system communication protocol, which is applied in The wireless communication between an on-vehicle device and a portable device that can be carried by a user can be effectively solved by using the present invention. That is, the main object of the present invention is to provide a car search system communication protocol. The car search system hardware includes a vehicle-mounted device and a portable device which can be carried by a user. By using the communication protocol described later, the user can activate the car search starter on the portable device, and the sound, light, and / or figure 200405674 displayed on the portable device display can be used to indicate the correct orientation of the vehicle position, so as to quickly Assistance in finding where the vehicle is parked. In order to achieve the above object, the present invention adopts the following technical solutions. The hardware of the car search system of the present invention mainly includes an on-vehicle device, which is pre-installed on the vehicle, and a carrying device, which is carried by the user. The on-board device includes a microprocessor, a receiving intensity indicator (RSSI), a transmitting and receiving module and an antenna, and is jointly installed in a shell; the carrying device includes an antenna, a transmitting and receiving module, a microprocessor, and a receiving intensity. The indicator (RSSI) and the signal display terminal are jointly installed on a shell, wherein a car search starter is provided on the surface of the housing of the carrying device for the user to operate the starter to start the car search function; a signal The display is arranged on the surface of the casing of the carrying device, and the results of the car search can be displayed by sound, light, and / or image. It is used for the communication protocol between the on-vehicle device and the portable device. The action flow includes: starting the car search starter, that is, the signal transmitted by the portable device is received by the on-vehicle device, and the internal code is compared. The on-board device is adjusted to the proper transmission power, and the signal is received by the carrying device, processed by the carrying device, and then displayed on the signal display to quickly find the position of the on-board device (vehicle parking). . The invention is particularly suitable for large parking lots that are not easy to find cars, or parking spaces of various large areas. When the user forgets the parking position, he or she only needs to press the car search starter, and according to the present invention, the correct position of the vehicle position can be indicated by the sound, light, and / or image screen. For a clearer understanding, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. [Embodiment] As shown in the first figure and the second figure, the communication protocol of the car-hunting system of the present invention is exclusively for wireless communication between a device 20 on a car and a carrying device 10 that can be carried by a user. communication.
