1. Field of the Invention
The present invention relates to a technology for transmitting data and forming a network topology, particularly to a system and method using a wireless tire pressure detector to transmit data and form a network topology.
2. Description of the Related Art
At present, manufacturers are developing a second advertisement mode, wherein advertisements are directly transmitted to an approaching mobile device. In the application, the user has to turn on the GPS system or the Bluetooth function of the mobile device. While the GPS system shows the current position of the mobile device, the advertisements of the nearby shops will be presented on the screen of the mobile device. Alternatively, the shop is equipped with a Bluetooth transmitter, such as iBeacon, and the Bluetooth transmitter will transmit advertisements to the nearby mobile devices whose Bluetooth devices are turned on.
If the Bluetooth function of a mobile device is not turned on, the mobile device would not receive advertisements. However, while the GPS system of a mobile device is turned on, the privacy of the user is leaked. Besides, advertisements from an iBeacon device can only be received by the mobile devices having the corresponding iBeacon application program. Therefore, a mobile device must have various iBeacon programs so as to receive advertisements from shops using different iBeacon devices, which is inconvenient for the user. Furthermore, some Bluetooth devices cannot communicate mutually unless they have been matched. However, Bluetooth matching may leak private information stored in mobile devices. Moreover, it is often too late to transmit advertisements because the distance between two Bluetooth devices may have exceeded the communication coverage before Bluetooth matching is completed
Accordingly, the present invention proposes a system and method using a wireless tire pressure detector to transmit data and form a network topology to overcome the abovementioned problems. The scheme and embodiments thereof will be described below.
The primary objective of the present invention is to provide a system and method using a wireless tire pressure detector to transmit data and form a network topology, wherein a second transmission module of a wireless tire pressure detector, which features uninterruptible power supply and low power consumption, persistently transmits broadcast information to or receives broadcast information from nearby devices, whereby a street-parking vehicle may also function as an advertisement vehicle.
Another objective of the present invention is to provide a system and method using a wireless tire pressure detector to transmit data and form a network topology, wherein related application programs are installed in a display device receiving broadcast information from a wireless tire pressure detector, such as a mobile device or a vehicular computer, and wherein the related application programs process the broadcast information and present advertisements in sequence, whereby the display device of the user needn't match with the display devices of others, wherefore the information security is promoted.
To achieve the abovementioned objectives, the present invention proposes a method using a wireless tire pressure detector to transmit data and form a network topology, wherein wireless tire pressure detectors are respectively installed in a plurality of vehicles, and wherein while a sender transmits broadcast information, the wireless tire pressure detectors of the vehicles receive the broadcast information and retransmit the broadcast information. The method of the present invention comprises steps: at least one sender persistently transmitting at least one piece of broadcast information; while a vehicle approaches the sender, a first transmission module of a wireless tire pressure detector of the vehicle detecting and receiving the broadcast information, and sending the broadcast information to a display device in a vehicle or storing the broadcast information in a cloud database and a second transmission module; the second transmission module transmitting the broadcast information to a wireless tire pressure detector of another vehicle; the display device using an application program to process and display the broadcast information. The display device includes a video device and an audio device.
The present invention also proposes a system using a wireless tire pressure detector to transmit data and form a network topology, which comprises a sender persistently transmitting at least one piece of broadcast information; and a receiver receiving the broadcast information while approaching the sender. In the present invention, the receiver is a vehicle and includes a wireless tire pressure detector using a first transmission module to receive the broadcast information from the sender and transmit the broadcast information to a display device of the vehicle and a second transmission module; the second transmission module transmitting the broadcast information to wireless tire pressure detector of another vehicle, wherein the first transmission device is installed inside the vehicle and also receives tire pressure information from the second transmission module, and wherein the second transmission module is installed in a tire of the vehicle and also transmits tire pressure information to the first transmission module; and a display device including a video device and an audio device, using an application program to display the broadcast information, which is received by the wireless tire pressure detector, with the video device or display the broadcast information with the video device and the audio device simultaneously.
Below, embodiments are described in detail to make easily understood the objectives, technical contents, characteristics and accomplishments of the present invention.
The present invention discloses a system and method using a wireless tire pressure detector to transmit data and form a network topology. Refer to

The sender may be an immobile shop or a mobile vehicle. As long as the sender is equipped with a broadcaster, the sender may be a vehicle, a shop, a person or an advertiser. Refer to

In addition to receiving the broadcast information transmitted by a sender 10 and displaying the broadcast information with the display device 24 (a mobile phone or a vehicle computer), the receiver 20 (a vehicle) can further use the second transmission module 224 of the wireless tire pressure detector 22 to broadcast the received information. Hence, the receiver 20 can also function as a sender. Thereby, the pass-on rate and exposure rate of broadcast information is increased. Therefore, a vehicle can function as a receiver and a sender simultaneously as long as the vehicle is equipped with a wireless tire pressure detector 22 and the related application program is installed in the display device 24 thereof. The coverage of a wireless tire pressure detector 22 is 15-20 m. Vehicles can receive and transmit broadcast information mutually as long as they are appearing within the coverage.
In the present invention, the wireless tire pressure detector functions as an intermediate device between the sender and the receiver. Thus, the present invention features that the sender would not directly transmit broadcast information to the display device of the receiver. Such a feature is due to the facts: a normal sender device, such as the Bluetooth device of a mobile device, is not a Bluetooth low energy device and unable to transmit data unless Bluetooth matching is done; however, the other will learn the Bluetooth ID of the mobile device through Bluetooth matching; a mobile device usually stores a lot of personal data; information security of a mobile device will be endangered if the mobile device undertakes Bluetooth matching and then transmits data; contrarily, the Bluetooth low energy device of a wireless tire pressure detector can directly receive the signals transmitted by another Bluetooth low energy device without Bluetooth matching; therefore, no matching is needed between the sender and the receiver. Thus, the driver using the present invention can directly obtain broadcast information from his own wireless tire pressure detector without any possibility of leaking the personal data stored in his display device no matter whether the display device is a vehicular computer or a mobile device. Further, the sender of the present invention can continuously broadcast information to the region neighboring the vehicle.
In the present invention, the receiver can receive broadcast information of different data formats or from different senders, and display the broadcast information with the display device; the sender can function as a receiver as long as the sender has a wireless tire pressure detector and a first transmission module to receive information.
In one embodiment, the broadcast information includes an advertisement serial number, a positional coordinates of a shop, advertisement contents, and the duration of a special offer. In one embodiment, the receiver includes a GPS device, which is normally integrated with the display device. For example, a GPS system is built in the vehicular computer or the mobile device. In the present invention, a piece of broadcast information is not necessarily presented on the display device immediately after it is received. It may be owing to that there are too many pieces of broadcast information received. In such a case, the pieces of broadcast information will be arranged in sequence according to geographic positions, time points of receiving the broadcast information, special offer durations, and other factors. For example, a shop issuing an advertisement is located in City A; while the vehicle is in City B, the display device will not display the advertisement; while the vehicle arrives at City A, the GPS device verifies the distance between the vehicle and the positional coordinates attached to each advertisement; then, the advertisements of the shops located in City A are retrieved and arranged in the queue for display. If an advertisement is too lengthy, the advertisement may be uploaded to a cloud database beforehand with a link to the cloud database attached to the advertisement. The driver can click on the display device to link to the cloud database or a related website.
Therefore, when the receiver receives broadcast information of a shop, the system needn't display the broadcast information immediately but has an option to arrange the broadcast information in the queue of the display device. Further, the system uses the GPS device to detect the current position and the distance between the current position and the shop. The display device will not display the broadcast information unless the distance between the current position and the shop is smaller than a preset value.
Refer to
In addition to persistently broadcasting information, the shop 34 (Shop C) further identifies the vehicles passing by to read the identity numbers of the first transmission modules of the vehicles (the receivers) and calculate the count of reading the identity number of each receiver so as to determine whether a receiver is a distinguished guest.
In one embodiment, the broadcast information does not include the positional coordinates of a shop but includes the serial number of the broadcast information, the identity number of the shop, the contents of the advertisement and the special offer duration. In the same embodiment, the receiver includes the lookup table of the identity numbers of shops and the positional coordinates of the shops. The receiver may be a vehicular computer or a mobile device. The receiver needn't have a GPS system. The lookup table can be downloaded from a cloud database. While a vehicle arrives at City A and receives the broadcast information of every shop, the system uses the identity numbers of the shops to look up the positional coordinates of the shops and determines the distances between the vehicle and the shops. Next, the system retrieves the advertisements of the shops in City A and arranges the advertisements in the queue for display. Then, the display device displays the advertisements in sequence.
In the same embodiment, while the receiver receives a piece of broadcast information of a shop, the system needn't display the broadcast information immediately but has an option to arrange the broadcast information in the queue of the display device. Next, the system uses the lookup table of the identity numbers of the shops and the positional coordinates of the shops to calculate the distance between the current position of the vehicle and the position of the shop of the advertisement to be displayed next. The display device will not display the advertisement of the shop until the vehicle moves to a position whose distance to the shop is smaller than a preset value, as shown in
In conclusion, the present invention proposes a system and method using a wireless tire pressure detector to transmit data and form a network topology, wherein a wireless tire pressure detector is equipped with a Bluetooth module including a first transmission module functioning as a scanner and a second transmission module functioning as a broadcaster. Owing to low power consumption, the second transmission can persistently transmit broadcast information no matter whether the vehicle is operating or shut down. The present invention uses the wireless tire pressure detector as an intermediate repeater, thus exempting the vehicular computer or the mobile device from directly Bluetooth matching with another's device and preventing from leakage of personal data. As vehicles are moveable, reciprocal data transmission among the vehicles would form a large network topology, expand the coverage of advertisements and increase exposure of advertisements.
The embodiments described are only to exemplify the present invention but not to limit the scope of the present invention. Any equivalent modification or variation according to the characteristic or spirit of the present invention is to be also included with the scope of the present invention.
