Description

[Technical field]

[0001] The present invention relates to a tire pressure detection device and an energy saving method with dynamic energy saving mechanism, especially to the technology applied in the field of vehicles. The main technology is that the center console receiver is installed at any position in the vehicle, messages are transmitted back and forth between each tire pressure detector and the center console receiver, the emission power, receiving sensitivity or data update frequency of each tire pressure detector is adjusted, each tire pressure detector is matched with the center console receiver in the best state, and the service life of each tire pressure detector is extended, which is a very practical invention. [Background technology]

[0002] Currently, in the regulations on safe driving, it is particularly important to make preparations in advance to prevent accidents on the road. For this reason, in recent years, vehicle regulations have strictly stipulated that vehicles must be equipped with tire pressure detectors, so that drivers can check whether the tire pressure of each tire is normal before driving, and ensure that each tire can be used normally after going on the road. Summary of the Invention [Problem to be solved by the invention]

[0003] However, after measuring the condition of each tire, the tire pressure detector attached to each tire transmits the measured information unidirectionally to a receiver (connected to the on-board computer or an independent device) installed in the vehicle, allowing the driver to directly observe the current condition of each tire. However, when the receiver is generally installed, it is often installed near the driver's seat so that the driver can easily see it, and the distance between the receiver and each tire is different. In addition, since the distance of each tire from the receiver is different, the distance of each tire pressure detector from the receiver is also different. In order to allow the receiver to fully receive signals and data, the range of the signal detected by each tire pressure detector is fixed, but the tire pressure detector closest to the receiver excessively wastes signal emission performance, and still has the same performance as the tire pressure detector that is far away. This method wastes electricity meaninglessly for the tire pressure detectors that are close, shortening the service life of the tire pressure detectors. However, tire pressure detectors that are directional in transmission cannot exchange information to optimize performance, and related parties have had to consider how to improve the above-mentioned problems.

[0004] With the current progress of science and technology, interconnection-oriented tire pressure detectors have been gradually introduced into the market, and more flexible product functions have been achieved through interconnection-based technology. The present invention mainly develops an energy-saving mechanism based on bidirectional transmission.

[0005] The present invention has been made in view of the above circumstances, and one of the objects of the present invention is to solve the above problems. The main object of the present invention is to provide a tire pressure detection device and an energy saving method having a dynamic energy saving mechanism. That is, the signal power emitted by each tire pressure detector is optimized for the position of the receiving device, reducing excessive consumption and waste of electricity and maintaining the service life of each tire pressure detector, thereby improving the drawback of the conventional tire pressure detector that the tire pressure detector closest to the receiving device emits a signal in a manner that wastes the most electricity in matching with the receiving device, which quickly shortens the service life of the tire pressure detector.

However, based on the range that the master receiver can receive, it is obvious that the closer the tire pressure detector is to the master receiver, the narrower the signal transmission range should be than the signal transmission range of the tire pressure detector that is farther away from the master receiver, so as to maintain the service life of each tire pressure detector and prevent all tire pressure detectors from wasting electricity. Therefore, the present invention is an invention with high practicality and inventive step, and is well worth promoting in the industry and disseminating to the public.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following examples, and can be modified as desired without departing from the gist of the present invention.

[0013] First, a tire pressure detecting device having a dynamic energy saving mechanism and an energy saving method according to the present invention will be described in detail with reference to Figs. 1 to 6.

[0014] The present invention has two embodiments for the structural part. The configuration of a tire air pressure detection device having a dynamic energy saving mechanism according to a first embodiment of the present invention is shown in Figs. 1 to 3.

[0015] The tire pressure detection device with a dynamic energy saving mechanism according to the present invention is attached to a vehicle 10, and comprises a plurality of tire pressure detectors 1 mounted on a plurality of tires 20 of the vehicle 10, each tire pressure detector 1 incorporating an 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 first information 2, the first information 2 being transmitted to the outside by a first transmission / reception unit 13 incorporated in each tire pressure detector 1, and the adjustment unit 11 adjusting and modifying the signal strength, reception sensitivity, or number of data updates of the first transmission / reception unit 13. The vehicle is equipped with a tire pressure detector 1, and a master receiver 3 which is mounted in the vehicle 10 and connected to each tire pressure detector 1, the master receiver 3 having a built-in second transceiver unit 31 and a control unit 32, the second transceiver unit 31 receiving the first information 2 and converting it to form second information 4, and the control unit 32 wirelessly controlling the adjustment unit 11 of each tire pressure detector 1 so as to adjust the signal strength, receiving sensitivity, or number of data updates when transmitting the first information 2 to the first transceiver unit 13 based on the content of the second information 4.

[0016] The energy saving method for the tire air pressure detection device according to the first embodiment mainly includes the following steps, each of which will be described below. <Initial matching step S1>: After the vehicle 10 is started and operating, power is supplied to multiple tire pressure detectors 1 and master receiver 3 to operate them, each tire pressure detector 1 is mounted on each tire 20 of the vehicle 10, the master receiver 3 is mounted at any position within the vehicle 10, and each tire pressure detector 1 is wirelessly connected bidirectionally to the serial number matching unit 33 of the master receiver 3 via the built-in serial number unit 14. <Initial signal comparison step S2>: After the vehicle 10 starts traveling, the detection unit 12 built into each tire pressure detector 1 detects the temperature and tire pressure of each tire 20 and forms first information 2, and then the first transceiver unit 13 built into each tire pressure detector 1 transmits the first information 2 to the second transceiver unit 31 built into the master receiver 3 by a wireless bidirectional transmission method, and the master receiver 3 generates second information 4 based on the signal strength, receiving sensitivity, or number of data updates when each first information 2 is transmitted, and the control unit 32 built into the master receiver 3 wirelessly controls the adjustment unit 11 of each tire pressure detector 1 so as to adjust and modify the signal strength, receiving sensitivity, or number of data updates when the first transceiver unit 13 transmits the first information 2 based on the content of the second information 4. <Repeated comparison step S3>: During the continuous running of the vehicle 10, each tire pressure detector 1 continuously and uninterruptedly transmits the first information 2 to the second transceiver unit 31 of the master receiver 3, and at the same time continuously and uninterruptedly generates the second information 4, and the adjustment unit 11 adjusts and modifies the signal strength, receiving sensitivity, or data update frequency when the first transceiver unit 13 transmits the first information 2 based on the contents of the second information 4 from time to time. <Memory storage S4>: After the vehicle 10 stops, the signal strength, receiving sensitivity, or number of data updates of the last first information 2 transmitted by the first transceiver unit 13 before the vehicle stops, and the serial number unit 14 of each tire pressure detector 1 are stored in the database 34 built into the master receiver 3, and the master receiver 3 is directly connected to each tire pressure detector 1 after the vehicle 10 is started next time.

[0017] Based on the above-mentioned structure and steps, the following will be described. When the vehicle 10 starts to be energized and starts up, power is supplied to each tire pressure detector 1 and the master receiver 3 to operate them. After starting up and operating, each tire pressure detector 1 is first matched and connected, and is matched to the serial number matching unit 33 built into the master receiver 3 in a wireless interconnection manner by the serial number unit 14 built into each tire pressure detector 1. The above-mentioned wireless interconnection manner is one of Bluetooth (registered trademark), ZigBee, LoRa, Sigfox, or NB-IoT. After confirming the connection, the temperature and tire pressure of each tire 20 are displayed on the main body of the master receiver 3 or on a screen connected to the master receiver 3 (recorded before the vehicle 10 stopped last time), and then the vehicle 10 starts to run and the transmission of signals between each tire pressure detector 1 and the master receiver 3 also starts. First, each tire pressure detector 1 forms the first information 2 for the temperature and tire pressure of the tire 20 after the vehicle has been driven, and the first transceiver unit 13 first transmits the first information 2 to the second transceiver unit 31 in the master receiver 3, which generates the second information 4 based on the transmission signal strength, reception sensitivity, or number of data updates of the first information 2. The content of this second information 4 includes the content of the first information 2, and signal strength information 41 and signal quality information 42 generated when the first transceiver unit 13 transmits. After the second information 4 is formed, the control unit 32 located in the master receiver 3 controls the adjustment unit 11 in each tire pressure detector 1 to operate in a wireless interconnection manner based on the content of the second information 4, and the adjustment unit 11 in each tire pressure detector 1 adjusts and modifies the signal strength, reception sensitivity, or number of data updates when the first transceiver unit 13 transmits the first information 2 based on the content of the second information 4.As shown in Figure 3, when the first information 2 has not yet been transmitted to the master receiver 3, the range of signal strength when the first transceiver unit 13 transmits the first information 2 is shown in the dashed line portion, and when comparison and transmission of the first information 2 are started, after the second information 4 is generated, each adjustment unit 11 adjusts the range of signal strength when the first transceiver unit 13 transmits the first information 2 so that it becomes as shown in the solid line portion.

[0018] As explained above, the closer the tire pressure detector 1 is to the master receiver 3, the narrower the signal strength range when its first transmitting / receiving unit 13 transmits the first information 2, but the signal is maintained within the range in which the master receiver 3 can receive the signal, and the amount of electricity is saved compared to the range generated by the initially transmitted signal (see the dashed line range), and the signal strength is concentrated and concentrated, so that the dissipation of the signal is avoided. In addition, the service life of the tire pressure detector 1 is also improved, as the output power is saved due to the reduction in signal strength and range, and the original service life of the tire pressure detector 1 is maintained by saving power, and a situation in which all tire pressure detectors 1 in the vehicle 10 are damaged at once or their service life is shortened and they all need to be replaced is avoided, and the cost of the tire pressure detectors 1 can be saved for the driver. In addition, by installing a database 34 built into the master receiver 3, the signal strength, receiving sensitivity, and number of data updates when the first transceiver unit 13 of each tire pressure detector 1 transmits are all recorded and stored before each stop, allowing the master receiver 3 and each tire pressure detector 1 to be directly and quickly connected after the next time the vehicle 10 is started.In addition, direct transmission is possible with signal strength, range, and quality that matches the distance between the first transceiver unit 13 and the master receiver 3, making it fast and hassle-free.

[0019] As described above, the contents of the first information 2 of the present invention include the temperature and tire pressure values ​​detected by each detection unit 12 for each tire 20. In addition, in order to improve driving safety, as shown in Fig. 1, each tire pressure detector 1 further includes a warning unit 15, and when the detection unit of each tire pressure detector 1 detects each tire 20 and finds an abnormality, it generates abnormality information 5, transmits the abnormality information 5, and activates the warning unit 15, and the warning unit 15 generates a warning signal 151 based on the contents of the abnormality information 5 and transmits it to the second transceiver unit 31 of the master receiver 3 together with the first information 2. In this way, a warning is issued as needed to the driver to pay attention to the condition of each tire 20, and the driver is stopped to ensure safety and solve the problem.

[0020] In addition, a tire pressure detection device and an energy saving method having a dynamic energy saving mechanism according to a second embodiment of the present invention are shown in Figures 4 to 6. The difference between the second embodiment and the first embodiment is that in the first embodiment, the control unit 32 built in the master receiver 3 mainly controls the adjustment unit 11 of each tire pressure detector 1, and adjusts and modifies the signal strength, reception sensitivity, or data update frequency when each first transceiver unit 13 transmits the first information 2. On the other hand, in the second embodiment of the present invention, the adjustment unit 11 of each tire pressure detector 1 actively adjusts and modifies the signal strength, reception sensitivity, or data update frequency when the first transceiver unit 13 transmits the first information 2. In the actual method of the second embodiment, each tire pressure detector 1 generates the first information 2 and transmits it to the second transceiver unit 31 by the first transceiver unit 13, and then the master receiver 3 performs comparison and matching, and then forms the feedback information 35. The feedback information 35 includes signal strength information 41 and signal quality information 42, and the feedback information 35 is obtained by performing relevant comparisons and calculations and then converting it according to the distance between the tire pressure detector 1 and the master receiver 3. The feedback information 35 is then returned to the first transceiver unit 13, and the adjustment unit 11 of each tire pressure detector 1 repeatedly transmits and compares the signal strength, reception sensitivity, or data update count when the first transceiver unit 13 retransmits the first information 2 based on the content of the returned feedback information 35, so that the master receiver 3 always obtains the highest signal strength, reception sensitivity, or data update count of each tire pressure detector 1.

[0021] The above is a description of the structure and method of the two embodiments of the present invention, allowing the driver to know the values ​​and parameters of each tire 20 at any time. For each tire pressure detector 1, the closer it is to the master receiver 3, the more the signal strength, reception sensitivity, or data update count during transmission will match the distance to the master receiver 3, eliminating the need for transmission within a fixed range as in the prior art, which would lead to a rapid shortening of the service life of each tire pressure detector. Each tire pressure detector 1 according to the present invention automatically and quickly adjusts the signal strength, reception sensitivity, or data update count during transmission of the first information 2 by the first transmitting / receiving unit 13 based on the position of the master receiver 3, reducing excessive power consumption, maintaining the service life of each tire pressure detector 1, and saving the cost of daily replacement.

[0022] The above description is for the purpose of explaining the present invention, and should not be interpreted as limiting the invention described in the claims or restricting the scope of the invention. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.
