Description

[Technical Field]

[0001] This invention is a wireless tire pressure detector Search and positioning system and how to implement it. [Background technology]

[0002] In modern traffic accidents, the proportion of accidents caused by tire failure is very high, especially when cars are traveling at high speeds. If a tire problem occurs suddenly, it can lead to serious accident consequences. Therefore, it is an important task for drivers to remember to check the tire pressure of their cars while driving.

[0003] With the advancement of driving needs and technology, products using wireless tire pressure detection are gradually being developed. This type of tire pressure detector detects tire information in real time, and transmits the tire information wirelessly to the host for analysis, so that drivers can easily know the tire status and maintain road safety.

[0004] In tire pressure detection systems on the market, the method adopted by tire pressure detectors to allow the host to distinguish between different wheels is often to use equipment to write the corresponding position and serial number of each tire pressure detector into the host, so that the host can identify and understand the tire pressure detector and wheel position represented by each serial number, which has a good effect on stability.

[0005] However, although this method is simple and effective, if the tire pressure detector needs to be replaced or the written information is incorrect, it usually has to be sent back to the factory for re-writing, which is extremely troublesome and likely to cause driving problems. When the tire pressure detector breaks and needs to be replaced, drivers may not pay attention to it or find it too much trouble to go and have it replaced, increasing the risk of driving on the road.

[0006] At the same time, conventional wireless tire pressure detectors only have the single function of transmitting data to the outside, so several wireless tire pressure detection systems have been developed as positioning methods, which use wireless tire pressure detectors to detect tire acceleration and measure wheel angle, which are then sent back to the host for calculation (see Patent Document 1 for an example). Alternatively, a wireless tire pressure detector can detect tire acceleration, determine whether the wheel is left or right, and send the information back to the host, which then adds signal strength information to allow the host to determine the wheel position (see Patent Document 2 for an example). However, all of these methods require the host to analyze the information detected by the wireless tire pressure detector. If there is noise interference while the vehicle is moving, a signal error will occur, making it difficult for the host to make a judgment, which can lead to incorrect measurement results or slow positioning.

[0007] Furthermore, if the angle or signal direction were measured only by the host, it would be impossible for a large truck with parallel tires to clearly distinguish between the inner, outer, front, and rear positions of the tires.

[0008] Therefore, if the above problems can be improved, it will increase the willingness and convenience of users to replace different tire pressure detectors, and reduce the trouble of returning them to the factory for reprogramming and the cost of replacing tire pressure detectors.

[0009] [Patent Document 1] US Patent No. US9463673B2 [Patent Document 2] US Patent No. US7010968B2 Summary of the Invention [Problem to be solved by the invention]

[0010] This invention is a wireless tire pressure detector Search and positioning system It includes a plurality of wireless tire pressure detectors and a wireless host. The plurality of wireless tire pressure detectors are installed on different rims, and each wireless tire pressure detector includes a sensing module and a main control module. The sensing module is used to sense tire information and transmits the sensed tire information to the main control module, which has the functions of transmitting data, receiving data, searching for other wireless devices, and sensing signal source strength.

[0011] The wireless host is installed in the automobile and includes a control module and a data transmission / reception module, of which the control module has the functions of searching for other wireless devices, detecting the signal source strength, and calculating and analyzing data, and the data transmission / reception module has the functions of transmitting data and receiving data.

[0012] After the wireless host and multiple wireless tire pressure detectors are wirelessly matched and connected via the wireless system, the wireless host selects a first wireless tire pressure detector from among the wireless tire pressure detectors, and the wireless host and the first wireless tire pressure detector collect one or two pieces of information, such as the signal strength and phase angle, from their own and the other wireless tire pressure detectors via the control module and main control module, respectively. The first wireless tire pressure detector then transmits the acquired information to the data transceiver module of the wireless host via the main control module, and then forwards it to the control module. The control module comprehensively compares the positioning results collected by the wireless host and the first wireless tire pressure detector, and accurately determines the position of the wheels on which each wireless tire pressure detector is installed. [Means for solving the problem]

[0013] To solve the problem, the present invention also provides a wireless tire pressure detector. Search and positioning system The present invention provides a method for implementing the above-mentioned method, which includes the following steps: a connection assignment step, a data collection step, a transmission and forwarding step, and a positioning analysis step.

[0014] The connection designation step refers to the operation of wireless pairing connection between the wireless host and each wireless tire pressure detector via the wireless system, and designating the first wireless tire pressure detector.

[0015] The data collection step refers to the operation in which, after the connection specification step is completed, the wireless host and the first wireless tire pressure detector connect to each other via the wireless system, sense and collect one or two pieces of information from the signal strength and the connection phase angle of the wireless tire pressure detector itself and the other wireless tire pressure detectors, and transmit the information to the control module and the main control module.

[0016] Next, the transmission and forwarding step refers to the operation of transmitting the information collected by the first wireless tire pressure detector through the main control module to the data transceiver module of the wireless host and then forwarding it to the control module after the data collection step is completed.

[0017] Finally, the positioning analysis step refers to the operation in which, after the transmission and forwarding step is completed, the control module analyzes, calculates, and compares all the information received, and thereby determines the wheel position where each wireless tire pressure detector is located.

[0018] The main purpose of this invention is to develop a wireless tire pressure detector. Search and positioning systemThe present invention also provides a method for implementing the same. A wireless host wirelessly pairs with multiple wireless tire pressure detectors, designating a first wireless tire pressure detector. Then, through the wireless pairing relationship, the wireless host and the first wireless tire pressure detector acquire one or two pieces of information from the other wireless tire pressure detectors, including the signal strength and phase angle of the information source. The first wireless tire pressure detector then transmits the acquired information to the wireless host for positioning analysis. This allows the wireless host to measure the wheel position where each wireless tire pressure detector is located. Unlike conventional programming methods, this eliminates the need to return the tire pressure detector to the factory to reprogram the serial number each time a tire pressure detector is replaced or added. Furthermore, because the system is dual-reference, even if interference occurs and information is lost between the wireless host and the first wireless tire pressure detector, positioning can still be performed using the information acquired by the other one. This double authentication method improves positioning accuracy and reduces the possibility of positioning errors. [Brief explanation of the drawings]

[0020] (One embodiment) The present invention will be described in detail below with examples and diagrams. The diagrams used in the text are intended to support and guide the specification, and do not represent the true proportions and correct layouts of the present invention after its implementation. Therefore, it should be noted that the proportions and layouts of the accompanying diagrams do not limit the scope of the claims.

[0021] As shown in Figures 1 to 3, the wireless tire pressure detector of the present invention Search and positioning system The wireless tire pressure detector 1 includes a plurality of wireless tire pressure detectors 1 and a wireless host 2. The plurality of wireless tire pressure detectors 1 are installed on different rims, and each wireless tire pressure detector 1 includes a sensing module 102 and a main control module 101. The sensing module 102 is used to sense tire information and transmits the sensed tire information to the main control module 101, which has the functions of transmitting data, receiving data, searching for other wireless devices, and sensing signal source strength.

[0022] 1, the wireless host 2 is installed in a vehicle, and includes a control module 201 and a data transmission / reception module 202. The control module 201 has the functions of searching for other wireless devices, detecting the signal source strength, and calculating and analyzing data, and the data transmission / reception module 202 has the functions of transmitting data and receiving data.

[0023] In addition, as shown in Figures 1 to 3, the dotted lines indicate the paths along which each wireless tire pressure detector 1 transmits data to the wireless host 2, and the solid lines indicate the paths along which the information transmitted by each wireless tire pressure detector 1 is integrated and transmitted.

[0024] After the wireless host 2 establishes a wireless matching connection with multiple wireless tire pressure detectors 1 via the wireless system, the wireless host 2 selects a first wireless tire pressure detector 11 from each of the wireless tire pressure detectors 1. The wireless host 2 and the first wireless tire pressure detector 11 then collect one or two pieces of information, namely, the signal strength and phase angle, from themselves and the other wireless tire pressure detectors 1 via the control module 201 and the main control module 101, respectively. The first wireless tire pressure detector 11 then transmits the acquired information to the data transceiver module 202 of the wireless host 2 via the main control module 101, and then forwards it to the control module 201. The control module 201 comprehensively compares and contrasts the positioning results collected by the wireless host 2 and the first wireless tire pressure detector 1, thereby accurately determining the position of the wheel on which each wireless tire pressure detector 1 is installed.

The first wireless tire pressure detector 11 transmits the data to the wireless host 2, which analyzes all the received information and compares and determines the wheel positions on which each wireless tire pressure detector 1 is located.

[0026] 3, in this embodiment, the primary method by which the first wireless tire pressure detector 11 detects the signal strength of itself and the other wireless tire pressure detectors 1 is determined based on distance. For example, if the first wireless tire pressure detector 11 is set to the right rear wheel, the first wireless tire pressure detector 11 will determine the strongest signal from the left rear wheel, the next strongest from the right front wheel, and the next strongest from the left front wheel, and so on, from near to far and from strong to weak.

[0027] Next, in this embodiment, the first wireless tire pressure detector 11 detects the phase angle of the other wireless tire pressure detector 1, as shown in Figure 3. If the first wireless tire pressure detector 11 is installed on the right rear wheel, the minimum angle θ1 of the other wireless tire pressure detector 1 corresponds to the right front wheel, the maximum angle θ2 corresponds to the left rear wheel, and the angle between the two corresponds to the left front wheel.

As shown in Figure 2, the present invention provides an implementation method, which includes a connection assignment step S10, a data collection step S11, a transmission and forwarding step S12 and a positioning analysis step S13.

[0033] The connection designation step S10 refers to the operation of wirelessly pairing the wireless host 2 and each wireless tire pressure detector 1 via the wireless system and designating the first wireless tire pressure detector 11.

[0034] The data collection step S11 refers to the operation in which, after completing the connection designation step S10, the wireless host 2 and the first wireless tire pressure detector 11 connect via the wireless system, sense and collect one or two pieces of information from the signal strength and the connection phase angle of its own and other wireless tire pressure detectors 1, and transmit them to the control module 201 and the main control module 101.
