Description

a luggage finder

technical field

The utility model relates to a wireless device, in particular to a baggage finder.

Background technique

When flying, some people need to check their luggage. After arriving at the destination, people wait for their luggage to be transported out of the conveyor belt. Because the suitcases of different people are sometimes very similar in appearance and color, when people identify their suitcases Mainly rely on eye observation, sometimes it may cause mistakes and bring inconvenience. At the same time, when taking a train, some people may forget to take their luggage or take someone else's luggage by mistake when getting off the train. Chinese Patent Publication No. CN2177307, published on September 14, 1994, discloses a kind of travel anti-theft pager in the utility model titled "Travel Anti-theft Pager", which consists of a monitor and a paging alarm It is mainly used to protect the safety of luggage and items during business trips and travels. The disadvantage is that the pager can only perform the anti-theft function, but it cannot actively find your own luggage.

Utility model content

The purpose of this utility model is to overcome the problem in the prior art that it is difficult for people to find luggage or easily lose luggage, and to provide a luggage finder, which can help people find luggage easily, or when the luggage leaves a certain distance from the person, it will disappear. Call the police.

The purpose of this utility model is to be realized through the following technical solutions:

A luggage finder, powered by a battery, is characterized in that it includes two wireless transmitting and receiving modules, one wireless transmitting and receiving module is set on the luggage, the other wireless transmitting and receiving module is set on the user, and the two wireless transmitting and receiving modules are connected by radio frequency signals. When in the search mode, the wireless transmitting and receiving module on the user's body transmits wireless signal data, and the wireless transmitting and receiving module on the luggage receives the matching wireless signal data, and reminds the user of the location of the luggage through sound and light, etc. When the user finds the luggage, The wireless transmitting and receiving module on the user stops transmitting wireless signal data, and the wireless transmitting and receiving module on the luggage stops audible and visual reminders. When in the lost mode, the wireless transmitting and receiving module on the luggage keeps transmitting the wireless signal data code, and the wireless transmitting and receiving module on the user keeps receiving the wireless signal data code. Once the user leaves the suitcase beyond the set distance, the wireless signal on the user The transmitting and receiving module cannot receive the wireless signal data code, and the wireless transmitting and receiving module on the user reminds the user that the luggage is far away from the user through sound and light.

As a preferred solution, the wireless transmitting and receiving module includes a single-chip microcomputer, keys, a display screen, a buzzer and a wireless module, and the single-chip microcomputer is simultaneously connected with the keys, the display screen, the buzzer and the wireless module. The display screen will send out a flashing signal, and the buzzer will sound, which can better remind the user.

As a preferred solution, the radio frequency signal is a 64-bit data code. The 64-bit data code has 2 to the 64th power of combinations, there are many combinations, and it is not easy to find transmission errors.

The beneficial effect of the utility model is that through the search mode of the luggage finder, the user can quickly find his luggage; through the anti-lost mode of the luggage finder, the user can ensure that his luggage will not be lost.

Among them: 1. SCM, 2. Button, 3. Display, 4. Buzzer, 5. Wireless module.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Embodiment: A luggage finder, powered by a battery, includes two wireless transmitting and receiving modules, one wireless transmitting and receiving module is set on the luggage, and the other wireless transmitting and receiving module is set on the user, between the two wireless transmitting and receiving modules Connected by radio frequency signal. The radio frequency signal is a 64-bit data code. The circuit principle connection diagram of the wireless transmitting and receiving module is shown in Figure 1, including a single-chip microcomputer, buttons, display screen, buzzer and wireless module, and the single-chip microcomputer is connected with the buttons, display screen, buzzer and wireless module at the same time.

The user presses a key to select a mode. When in search mode, the wireless transmitting and receiving module on the user transmits wireless signal data, and when the luggage is within 50 meters from the user, the wireless transmitting and receiving module of the luggage receives the matching wireless signal data, the display screen flashes, and the buzzer sounds to remind the user of the luggage position, when the user finds the luggage, the wireless transmitting and receiving module on the user stops transmitting wireless signal data, and the wireless transmitting and receiving module on the luggage stops reminding. When in the lost mode, the wireless transmitting and receiving module on the luggage keeps transmitting the wireless signal data code, and the wireless transmitting and receiving module on the user keeps receiving the wireless signal data code. Once the user leaves the suitcase for more than 5 meters, the wireless transmitting and receiving module on the user The module cannot receive the wireless signal data code, and the wireless transmitting and receiving module on the user reminds the user that the luggage is far away from the user through the flashing of the display screen and the sound of the buzzer.
