Tire pressure detecting device group with Bluetooth signal conversion

The present invention relates to a tire pressure detector, and more particularly to a tire pressure detecting device group with Bluetooth signal conversion.

According to the car accident, a large part of the cause of the accident is due to tire blasting or wheel detachment, especially when driving on the highway too fast, or long-distance driving without paying attention to the tire condition, especially prone to tire overheating, tire The tire pressure detector has come into being. The tire pressure detector has to be installed, and the tire pressure detector detected by the tire pressure detector will be transmitted to the tire pressure detector. In the central control system of the car, once the abnormal information of the tire is detected, the driver can be immediately alerted.

At present, the transmission mode of the tire pressure detector is transmitted through the RF frequency of 433 or 315 MHz, and the central control system of the vehicle can only receive the RF signal, but the disadvantage that the tire is too far from the central control system and the single frequency is the vehicle and the vehicle. The signals between the tires and the tires are easy to interfere with each other, and the speed of the RF signal transmission is slow, and the working time is long, resulting in high power consumption. Moreover, the tire pressure detectors of the current brands have no fixed data encoding format, even Different types and models of the same car manufacturer will have different data encoding formats, so the tire pressure detectors of different models and different brands cannot be used universally; in addition, the current tire pressure detector has only one direction. The ability to transfer data, unable to receive data, two-way transmission, if you need two-way transmission, you need to add another low Frequency receivers, these are the disadvantages of the tire pressure detector transmitting data to the central control system by means of RF signals. The invention patent of No. I293926 discloses a programmable universal tire pressure sensor setting system and method, which is built in a tire pressure detector and has a program coding device, which is sent according to the external monitoring device according to the coding requirements of the external monitoring device. The signal in the encoded format of the device, but this disadvantage is that the tire pressure detector of each tire must be encoded. Furthermore, in view of the increasing popularity of tire pressure detecting elements for transmitting tire pressure data by Bluetooth signals, the receiving system of the tire pressure detecting elements of the original in-vehicle central control system is in the 433 or 315 MHz frequency band, resulting in a new replacement. The Bluetooth tire pressure detecting component cannot be detected by the original in-vehicle central control system, resulting in an incompatible condition.

Therefore, this creation proposes a tire pressure detecting device group with Bluetooth signal conversion, which replaces the signal sent by the tire pressure detector with a Bluetooth signal, and then converts it into an RF signal and transmits it to the vehicle central control system to solve the above problem. The problem, the specific architecture and its implementation will be detailed below:

The main purpose of the present invention is to provide a tire pressure detecting device group with Bluetooth signal conversion, which is designed to transmit a tire pressure detecting component for transmitting a Bluetooth signal, and convert a Bluetooth signal into an RF signal by using a signal conversion component to enable tire pressure detection. The message sent by the measuring component can be received by the in-vehicle central control system that only receives the RF signal.

Another object of the present invention is to provide a tire pressure detecting device group with Bluetooth signal conversion, which has a signal conversion component disposed in the vehicle, not only close to the central control system in the vehicle, but also avoids radio frequency with other vehicles. The problem of mutual interference of signals can reduce the cost of setting a signal conversion component on each tire.

Another purpose of this creation is to provide a tire pressure detection with Bluetooth signal conversion. The device group, in which the tire pressure detecting component is transmitted by using a Bluetooth signal, can control the tire pressure detecting component end or the signal conversion component end through a mobile device (such as a smart phone or a tablet computer).

Another object of the present invention is to provide a tire pressure detecting device group with Bluetooth signal conversion, wherein the signal conversion component can be an in-vehicle charging device (such as a cigarette lighter or a charger), so that the mobile device can be plugged into the signal. Simultaneous charging and signal transmission on the conversion component.

Another object of the present invention is to provide a tire pressure detecting device group with Bluetooth signal conversion, which stores a data encoding format in a signal conversion component, reduces the data size of the Bluetooth signal, and speeds up the transmission speed.

For the above purposes, the present invention provides a tire pressure detecting device set with Bluetooth signal conversion, comprising at least one tire pressure detecting component and a signal converting component, wherein the tire pressure detecting component is disposed on a tire of the vehicle, To detect the information of the tires and send out a Bluetooth signal; the signal conversion component is located in the vehicle and can be located close to the central control system of the vehicle. After receiving the Bluetooth signal, the data is transmitted according to different models and different data encoding formats. The conversion of the encoding format converts the Bluetooth signal into an RF signal and transmits the RF signal to the wireless RF receiver of one of the in-vehicle central control systems.

Figures 4A and 4B show an embodiment of the data encoding format of the tire pressure detecting elements of two different vehicle models.

The present invention provides a tire pressure detecting device group with Bluetooth signal conversion. Please refer to FIG. 1A and FIG. 1B, which is a schematic diagram of assembling a tire pressure detecting device with Bluetooth signal conversion on a vehicle.

The tire pressure detecting device set of the present invention includes at least one tire pressure detecting component 14 and a signal converting component 16 , which are disposed on a vehicle 10 , wherein the tire pressure detecting component 14 is disposed in the vehicle 10 . Each of the tires 12 is provided with a tire pressure detecting element 14; the signal converting element 16 is disposed in the vehicle at a position closer to an in-vehicle central control system 18.

The tire pressure detecting component 14 is provided with a first Bluetooth module (not shown) and a first microprocessor (not shown), please also refer to FIG. 2, which is the tire pressure detection in the creation. Step S10, the tire pressure detecting component 14 first detects the tire information, including the temperature, pressure, battery voltage and the like of the tire 12, and then the first microprocessor fills the tire information into the tire pressure detection in step S12. In the data encoding format of the measuring component 14, finally, as described in step S14, the Bluetooth signal including the tire temperature, the pressure, and the battery power of the tire pressure detecting component is transmitted to the signal conversion component 16 by using the first Bluetooth module. .

The signal conversion component 16 is provided with a second Bluetooth module (not shown), a second microprocessor (not shown), and a radio frequency transmitter (not shown). Please refer to FIG. 3 at the same time. It is a flowchart of the signal conversion component in the creation. After the second Bluetooth module in the signal conversion component 16 receives the Bluetooth signal sent by the tire pressure detecting component 14 in step S22, the second microprocessor is used in step S22. The data encoding format is converted according to different models and different data encoding formats, and the Bluetooth signal is converted into an RF signal. Finally, in step S24, the RF transmitter in the signal converting component 16 transmits the RF signal, and the in-vehicle central control system One of the 18 RF signal receivers (not shown) receives.

The first Bluetooth module in the tire pressure detecting component 14 and the second Bluetooth module in the signal converting component 16 are both Low Voltage Bluetooth Low Energy, which consumes a small amount of power, and is therefore installed in the tire pressure detection. The test element 14 does not consume too much power, so that the tire pressure detecting element 14 can maintain normal operation. The frequency of the RF signal in the signal conversion component 16 is two frequency bands of 315 and 433 MHz. Since the in-vehicle central control system 18 can only receive the RF signal and cannot receive the Bluetooth signal, the signal conversion component 16 is installed in the vehicle and the vehicle. The internal control system 18 is close to the outside and will not be interfered by other signals, and will not be received by other vehicles.

In this creation, the specific data transmission format of the tire pressure detecting components of different models and different brands is stored in the signal conversion component 16 or the cloud database (not shown), so even the tire pressure detecting component 14 The format of the transmitted data is different, and can still be converted into an RF signal in the signal conversion component 16 and transmitted to the in-vehicle central control system 18. In addition, the data encoding format is stored in the signal conversion component 16 and is not stored in the tire pressure detecting component 14, so that the information of the data encoding format is not required to be included in the Bluetooth signal, thereby reducing the data size of the Bluetooth signal and speeding up the transmission speed. .

4A and 4B are embodiments of the data encoding format of the tire pressure detecting component of two different vehicle models, and the data encoding format of each tire pressure detecting component includes the identification code of the tire pressure detecting component, Information such as pressure, battery voltage and tire temperature, which are based on different information The tire pressure detectors of different models or different brands may occupy different numbers of bits, and the order of storage may also be different. In the embodiment of FIG. 4A, the tire pressure detecting element needs to be subjected to four cycles first. After preheating, the 14-bit identification code, the 11-bit pressure data, the 11-bit battery voltage data, and the 12-bit temperature data are stored. In the embodiment of FIG. 4B, the tire pressure detecting component is required. After five cycles of preheating, the 10-digit identification code, the 10-bit battery voltage data, the 14-bit pressure data, and the 12-bit temperature data are stored, so that the tire pressure in Figure 4B is known. The data encoding format of the detecting component is one bit larger than the data encoding format of the tire pressure detecting component in FIG. 4A, the data storage order is different, and the number of bits occupied by each data is also different.

Since the tire pressure detecting element is transmitted by using a Bluetooth signal, the tire pressure detecting element end or the signal converting element end can be controlled by a mobile device such as a smart phone or a tablet computer. In addition to the generally simple conversion component, the signal conversion component can also be an in-vehicle charging device (such as a cigarette lighter or a charger), so that the mobile device can be plugged into the signal conversion component for charging and signal transmission simultaneously. It is more convenient for the mobile device to control the signal conversion component, whereby the tire pressure detecting component and the signal conversion component can be bidirectionally transmitted, and can simultaneously receive and transmit signals and data; in addition, since the original signal of the tire pressure detecting component is a Bluetooth signal Therefore, it is more versatile and can use the tire pressure detecting element to communicate with other tire pressure detecting elements passing through the vehicle to transmit information.

The format converts the data encoding format, converts the Bluetooth signal into an RF signal and transmits it to the in-vehicle central control system. Since the signal conversion component is located in the car and is close to the central control system in the vehicle, the central control system in the vehicle can be ensured.
