Abstract
Description
Technical Field
[0001] The present invention relates to a tire pressure monitoring device and energy-saving method with a dynamic energy-saving mechanism, specifically a technology applicable to the vehicle body field. The main technology lies in that each tire pressure detector can transmit information back and forth with the central control receiver based on the location of the central control receiver in the vehicle, thereby adjusting the transmission power, receiving sensitivity or data update frequency of each tire pressure detector, so that each tire pressure detector can be matched with the central control receiver in an optimal state and the service life of each tire pressure detector can be shortened. This invention is an extremely practical invention. Background Art
[0002] In today's regulations on driving safety, in order to avoid danger after driving, pre-driving preparation is particularly important. For this reason, in recent years, relevant regulations on vehicle bodies have strictly stipulated that vehicles must be equipped with tire pressure monitors. This allows drivers to check whether the tire pressure of each tire is normal before driving, ensuring the use of each tire after driving.
[0003] However, after the tire pressure detectors installed on each tire measure the status of each tire, they will broadcast the measured information in a one-way manner to a receiving device installed in the vehicle body (which can be connected to the vehicle computer or an independent device) so that the driver can directly view the current status of each tire. However, when installing the receiving device, in order to facilitate the driver's viewing, the receiving device is usually installed near the driver's seat, resulting in a different distance between the position of each tire and the receiving device. Because the distance between each tire and the receiving device is different, the distance between each tire pressure detector and the receiving device is also different. However, in order to ensure that the receiving device can fully receive the signal and data, the signal range detected by each tire pressure monitor is fixed. However, this also causes the tire pressure monitor closest to the receiving device to waste too much signal transmission efficiency, but the efficiency is the same as that of the tire pressure monitor farther away. This method is undoubtedly a waste of power for the closer tire pressure monitor, thereby shortening the service life of the tire pressure monitor. However, broadcast-oriented tire pressure monitors cannot exchange information to achieve performance optimization. Relevant industry players must consider how to improve and prevent the above-mentioned problems from occurring.
[0004] Due to current technological advancements, tire pressure monitors with bidirectional links are gradually being introduced into the market. Bidirectional link-based technologies can achieve more flexible product functions. Therefore, the present invention can primarily develop a power-saving mechanism based on bidirectional transmission. Summary of the Invention
[0005] To improve the matching between existing tire pressure monitors and receivers, the tire pressure monitors closest to the receiver transmit signals in a manner that wastes the most power, thereby rapidly shortening the lifespan of the monitors. The present invention provides a tire pressure monitor device and energy-saving method with a dynamic energy-saving mechanism. These ensure that the signal power transmitted by each tire pressure monitor is optimally positioned relative to the receiver, reducing excessive power consumption and waste, thereby maintaining the lifespan of each tire pressure monitor.
[0006] The technical solution adopted by the present invention to solve its technical problem is:
[0007] The present invention has two embodiments. The first embodiment is a tire pressure monitoring device with a dynamic energy-saving mechanism, which is installed on a vehicle body and includes: a plurality of tire pressure detectors, which are respectively installed on a plurality of tires on the vehicle body, each tire pressure detector having a built-in adjustment unit and a detection unit. The detection unit detects the tire pressure and temperature of the corresponding tire and generates a first message. The first message is sent to the outside by a first transceiver unit built in each tire pressure detector. The adjustment unit adjusts and changes the signal strength, reception sensitivity or data update frequency of the first transceiver unit; and a main control receiver, which is installed in the vehicle body and wirelessly connected to each tire pressure detector in a two-way manner. The main control receiver has a built-in A second transceiver unit and a control unit, wherein the second transceiver unit receives the first information and converts it into a second information, and the control unit wirelessly controls the adjustment unit of each tire pressure detector based on the content of the second information to adjust the signal strength, reception sensitivity, or data update frequency when the first transceiver unit sends the first information; wherein, through the information transmission between each tire pressure detector and the main control receiver, the signal transmission range of each tire pressure detector in the transmission of the first information can match the distance between the main control receiver.
[0008] Furthermore, a second embodiment of the present invention is a tire pressure monitoring device with a dynamic energy-saving mechanism, which is installed on a vehicle body and includes: a plurality of tire pressure detectors, which are respectively installed on a plurality of tires on the vehicle body, each tire pressure detector having a built-in adjustment unit and a detection unit, the detection unit detecting the tire pressure and temperature of the corresponding tire and generating a first message, the first message being sent to the outside by a first transceiver unit built in each tire pressure detector, and the adjustment unit adjusting and changing the signal strength, receiving sensitivity or data update frequency of the first transceiver unit; and a main control receiver, which is installed in the vehicle body and wirelessly connected to each tire pressure detector in a two-way manner, the main control receiver having a built-in second transceiver unit, the first signal of each tire pressure detector After the information is transmitted to the second transceiver unit, the second transceiver unit generates a feedback information after receiving it, and the feedback information is then transmitted back to the first transceiver unit by the second transceiver unit. After each tire pressure detector receives the feedback information, the adjustment unit is activated. The adjustment unit adjusts and changes the signal strength, receiving sensitivity or data update frequency of the first transceiver unit according to the content of the feedback information; wherein, through the repeated transmission of information between each tire pressure detector and the main control receiver, the signal transmission range of each tire pressure detector in the transmission of the first information can match the distance between the main control receiver.
[0009] In addition, according to the first embodiment, the present invention also has an energy-saving method for a tire pressure detection device, the steps of which include: initial matching: after a vehicle body starts operating, power is supplied to several tire pressure detectors and a main control receiver for operation, and each tire pressure detector is installed on each tire of the vehicle body, and the main control receiver is installed at any position in the vehicle body, and each tire pressure detector transmits the signal to a serial number matching unit of the main control receiver using a built-in serial number unit; first signal comparison: after the vehicle body starts moving, each tire pressure detector uses a built-in detection unit to detect the temperature and tire pressure of each tire and form a first information, and then a first transceiver unit built into each tire pressure detector transmits the first information to a second transceiver unit built into the main control receiver in a wireless two-way transmission manner, and the main control receiver generates a second information based on the signal strength and quality of each first information transmitted, and a control unit built into the main control receiver The control unit will wirelessly control an adjustment unit of each tire pressure detector to adjust and change the signal strength, reception sensitivity or data update frequency of the first information sent by the first transceiver unit according to the content of the second information; repeated comparison: during the continuous movement of the vehicle, each tire pressure detector will continuously send the first information to the second transceiver unit of the master control receiver, and will also continuously generate the second information, so that the adjustment unit can adjust and change the signal strength, reception sensitivity or data update frequency of the first transceiver unit when sending the first information according to the content of the second information at any time; memory storage: after the vehicle is turned off, a database built into the master control receiver will store the message, signal strength, signal quality and serial number unit of each tire pressure detector of the last first information sent by the first transceiver unit before the vehicle is turned off, so that the master control receiver and each tire pressure detector can be directly connected when the vehicle is started next time.
[0010] Furthermore, according to a second embodiment of the present invention, there is also provided a method for saving energy for a tire pressure monitoring device, the steps of which include: Initial matching: After a vehicle starts operating, power is supplied to several tire pressure detectors and a master receiver for operation. Each tire pressure detector is installed on each tire of the vehicle, and the master receiver is installed at any location within the vehicle. Each tire pressure detector uses a built-in serial number unit to wirelessly and bidirectionally connect to a serial number matching unit of the master receiver. First signal comparison: After the vehicle begins moving, each tire pressure detector uses a built-in detection unit to detect the temperature and tire pressure of each tire and generate a first signal. Then, a first transceiver unit built into each tire pressure detector transmits the first signal to a second transceiver unit built into the master receiver via wireless bidirectional transmission. The master receiver generates feedback information based on the signal strength, reception sensitivity, or data update count of each first signal. The second transceiver unit built into the master receiver transmits the feedback information back to each first transceiver unit. An adjustment unit built into each tire pressure detector adjusts and changes the signal strength, reception sensitivity or data update frequency of the first transceiver unit when sending the first information based on the feedback information sent back; repeated comparison: during the continuous movement of the vehicle, each tire pressure detector will continuously send the first information to the second transceiver unit of the master receiver, and will also continuously generate feedback information, so that the adjustment unit can adjust and change the signal strength, reception sensitivity or data update frequency of the first transceiver unit when sending the first information based on the content of the feedback information at any time; memory storage: after the vehicle is turned off, a database built into the master receiver will store the message, signal strength, signal quality and serial number unit of the last first information sent by the first transceiver unit before the vehicle is turned off, so that the master receiver and each tire pressure detector can be directly connected when the vehicle is started next time.
[0011] In summary, the advantages of the present invention, as defined within the tire pressure monitoring device and dynamic adjustment method, lie in that, when each tire pressure detector is coupled with the master receiver, each tire pressure detector can adjust or vary the signal strength, reception sensitivity, or data update frequency of the first information transmitted by the first transceiver unit according to its distance from the master receiver. Simply put, the closer the tire pressure detector is to the master receiver, the smaller the range of signal strength it transmits, but this range is still based on the receivable range of the master receiver. Specifically, the signal transmission range of tire pressure detectors closer to the master receiver is smaller than that of tire pressure detectors farther away from the master receiver. This ensures that the service life of each tire pressure detector is maintained, preventing all tire pressure detectors from wasting power. Therefore, the present invention is highly practical and progressive, worthy of promotion by the industry and public disclosure.
[0012] The beneficial effect of the present invention is that it allows the signal power emitted by each tire pressure detector to be optimal in relation to the position of the receiving device, thereby reducing excessive power consumption and waste, thereby maintaining the service life of each tire pressure detector.

[0045] In order to clearly illustrate that the present invention can achieve the above-mentioned purpose and effect, the following embodiments of the present invention are described in detail with reference to the accompanying drawings. Figures 1 to 6 As shown, first of all, there are two embodiments of the present invention in the structural part. First of all, for the first embodiment of the present invention ( Figures 1 to 3 ), a tire pressure monitoring device with a dynamic energy-saving mechanism, installed on a vehicle body 10, comprising: a plurality of tire pressure detectors 1, which are respectively installed on a plurality of tires 20 on the vehicle body 10, each tire pressure detector 1 having a built-in adjustment unit 11 and a detection unit 12, the detection unit 12 detecting the tire pressure and temperature of the corresponding tire 20 and generating a first message 2, the first message 2 being transmitted externally by a first transceiver unit 13 built into each tire pressure detector 1, and the adjustment unit 11 adjusting and changing the signal strength, receiving sensitivity, or data update frequency of the first transceiver unit 13; and a The main control receiver 3 is installed in the vehicle body 10 and is connected to each tire pressure detector 1. The main control receiver 3 has a built-in second transceiver unit 31 and a control unit 32. The second transceiver unit 31 receives the first information 2 and converts it into a second information 4. The control unit 32 wirelessly controls the adjustment unit 11 of each tire pressure detector 1 according to the content of the second information 4 to adjust the signal strength, reception sensitivity or data update frequency when the first transceiver unit 13 sends the first information 2.
[0046] The automatic adjustment method of the tire pressure monitoring device according to the first embodiment includes the following steps: initial matching S1: after the vehicle body 10 starts to operate, power is supplied to the plurality of tire pressure detectors 1 and the main control receiver 3 for operation. Each tire pressure detector 1 is installed on each tire 20 of the vehicle body 10, and the main control receiver 3 is installed at any position in the vehicle body 10. Each tire pressure detector 1 is wirelessly and bidirectionally connected to a serial number matching unit 33 of the main control receiver 3 via a built-in serial number unit 14; first signal comparison S2: after the vehicle body 10 starts to move, each tire pressure detector 1 uses a built-in detection unit 12 to perform temperature measurement on each tire 20. The tire pressure and tire temperature are detected and a first message 2 is formed. Then, a first transceiver unit 13 built into each tire pressure detector 1 transmits the first message 2 to a second transceiver unit 31 built into the main control receiver 3 in a wireless two-way transmission manner. The main control receiver 3 generates a second message 4 according to the signal strength, reception sensitivity or data update frequency of each first message 2 transmitted. A control unit 32 built into the main control receiver 3 wirelessly controls an adjustment unit 11 of each tire pressure detector 1 to adjust and change the signal strength, reception sensitivity or data update frequency of the first message 2 sent by the first transceiver unit 13 according to the content of the second message 4.
[0047] Repeated comparison S3: As the vehicle 10 continues to move, each tire pressure detector 1 will continuously send the first message 2 to the second transceiver unit 31 of the master receiver 3, and will also continuously generate the second message 4, so that the adjustment unit 11 can adjust and change the signal strength, reception sensitivity or data update frequency of the first transceiver unit 13 when sending the first message 2 according to the content of the second message 4 at any time; memory storage S4: After the vehicle 10 is turned off, a database 34 built into the master receiver 3 will store the signal strength, reception sensitivity or data update frequency of the last first message 2 sent by the first transceiver unit 13 before the vehicle is turned off, as well as the serial number unit 14 of each tire pressure detector 1, so that the master receiver 3 and each tire pressure detector 1 can be directly connected when the vehicle 10 is started next time.
[0048] According to the description of the above structure and steps, when the vehicle body 10 starts to be powered on and started, power will be supplied to each tire pressure detector 1 and the main control receiver 3 for operation. After the startup operation, each tire pressure detector 1 will first be matched and connected, and the built-in serial number unit 14 of each tire pressure detector 1 will be matched with the built-in serial number matching unit 33 of the main control receiver 3 in a wireless two-way connection manner, wherein the above-mentioned wireless two-way connection method can be any of Bluetooth, ZigBee, LoRa, Sigfox or NB-IoT. After confirming the connection, the main control receiver 3 body or the screen connected to the main control receiver 3 will display the temperature and tire pressure of each tire 20 (the record before the last vehicle body 10 was turned off). Then the vehicle body 10 will start to move and the signal transmission between each tire pressure detector 1 and the main control receiver 3 will start. First, each tire pressure detector 1 will detect the tire after the vehicle body moves. 20's temperature and tire pressure form the first information 2, and the first transceiver unit 13 first transmits the first information 2 to the second transceiver unit 31 in the master receiver 3. The second transceiver unit 31 then generates the second information 4 based on the transmission signal strength, reception sensitivity, or data update frequency of the first information 2. The content of this second information 4 includes the content of the first information 2, a signal strength information 41 and a signal quality information 42 generated when the first transceiver unit 13 transmits it. After the second information 4 is generated, the control unit 32 in the master receiver 3 controls the operation of the adjustment unit 11 in each tire pressure detector 1 in a wireless two-way connection according to the content of the second information 4. The adjustment unit 11 in each tire pressure detector 1 adjusts and changes the signal strength, reception sensitivity, or data update frequency of the first transceiver unit 13 when sending the first information 2 according to the content of the second information 4. Figure 3 As shown, when the first information 2 has not yet been transmitted to the main control receiving component 3, the signal strength range of the first information 2 sent by the first transceiver unit 13 is the dotted line part, and when the comparison, transmission of the first information 2, and generation of the second information 4 are started, each adjustment unit 11 adjusts the signal strength range of the first information 2 transmitted by the first transceiver unit 13 to the solid line part.
[0049] According to the above description, it can be seen that the closer the tire pressure detector 1 is to the main control receiver 3, the smaller the signal strength range of its first transceiver unit 13 when sending the first information 2 becomes, but it still remains within the range that the main control receiver 3 can receive. Compared with the range generated when the signal is initially sent (dashed line range), it can save more power, and the signal strength is more condensed and concentrated, avoiding signal dissipation. In addition, the service life of the tire pressure detector 1 is extended because of the reduction in signal strength and range, which makes the power consumed more economical. The power saving maintains the original service life of the tire pressure detector 1, avoiding all tire pressure detectors 1 on the vehicle body 10 from being damaged. The driver can save the cost of the tire pressure detectors 1 by avoiding the need to replace all of them due to damage and shortened service life. In addition, the built-in database 34 of the master receiver 3 allows the signal strength, reception sensitivity, or data update frequency of the first transceiver unit 13 of each tire pressure detector 1 to be recorded and memorized before each engine shutdown. This allows the master receiver 3 to quickly connect to each tire pressure detector 1 the next time the vehicle 10 is started. In addition, the first transceiver unit 13 can also directly send a signal strength, range, and quality that matches the distance between the master receiver 3, which is both fast and convenient.
[0050] According to the above description, the first information 2 of the present invention includes the temperature and tire pressure values detected by each detection unit 12 for each tire 20; in addition, in order to improve driving safety, please see Figure 1 As shown, each tire pressure detector 1 further has a built-in warning unit 15. The detection unit of each tire pressure detector 1 detects each tire 20 and generates an abnormality message 5 when an abnormality is found. The abnormality message 5 is transmitted and the warning unit 15 is activated. The warning unit 15 generates a warning signal 151 based on the content of the abnormality message 5 and transmits it along with the first message 2 to the second transceiver unit 31 of the main control receiver 3. This can remind the driver to pay attention to the condition of each tire 20 at any time, and stop driving to ensure safety and solve the problem.
[0051] Another embodiment of the present invention is shown in Figures 4 to 6The structure and method of the second embodiment of the present invention are shown. The second embodiment is different from the first embodiment in that the first embodiment mainly uses the control unit 32 built into the main control receiver 3 to control the adjustment unit 11 of each tire pressure detector 1, thereby adjusting and changing the signal strength, reception sensitivity or data update frequency of each first transceiver unit 13 when sending the first information 2. In contrast, in the second embodiment of the present invention, the adjustment unit 11 of each tire pressure detector 1 actively adjusts and changes the signal strength, reception sensitivity or data update frequency of the first transceiver unit 13 when sending the first information 2. The actual method of the second embodiment is that after each tire pressure detector 1 generates the first information 2 and transmits it to the second transceiver unit 31 through the first transceiver unit 13, the main control receiver After comparison and matching, feedback information 35 is generated. This feedback information 35 includes signal strength information 41 and signal quality information 42. This feedback information 35 is converted based on the distance between the tire pressure detector 1 and the master receiver 3 after the relevant comparison and calculation. The feedback information 35 is then transmitted back to the first transceiver unit 13. The adjustment unit 11 of each tire pressure detector 1 then adjusts the signal strength, reception sensitivity, or data update frequency when the first transceiver unit 13 retransmits the first information 2 based on the content of the returned feedback information 35. Through repeated transmission and comparison, the master receiver 3 can always obtain the optimal signal strength, reception sensitivity, or data update frequency of each tire pressure detector 1.
[0052] In summary, with the two embodiments and methods described herein, the driver can be aware of the various values and parameters of each tire 20 at any time. Furthermore, for each tire pressure detector 1, the closer it is to the main control receiver 3, the more the signal strength, reception sensitivity, or data update frequency can be matched to the distance from the main control receiver 3. This eliminates the need to limit transmission to a fixed range as in the prior art, which would cause the service life of each tire pressure detector to be rapidly reduced. In contrast, each tire pressure detector 1 of the present invention can automatically and quickly adjust the signal strength, reception sensitivity, or data update frequency of the first transceiver unit 13 when sending the first information 2 according to the position of the main control receiver 3, thereby reducing excessive power consumption, maintaining the service life of each tire pressure detector 1, and saving the cost of frequent replacement.
[0053] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
