[0002] INDEPENDENTLY MONITORABLE TIRE PRESSURE MONITORING SYSTEM

[0003] Technical Field of the Invention

[0004] The invention relates to an independently monitorable tire pressure monitoring system that measures the instantaneous pressure levels and temperature changes inside tires via valve sensors attached to the tires, transmits these through a centralized communication system, and eliminates data loss issues in long vehicles.

[0005] State of the Art

[0006] TPMS stands for "Tire Pressure Monitoring System". This system continuously monitors the pressure of a vehicle's tires and alerts the driver when the pressure in the tires drops or rises excessively. TPMS is recognized as an important feature for improving safety, reducing tire wear, and improving fuel efficiency.

[0007] In the state of the art, short-distance communication infrastructures are generally preferred in TPMS systems. An example of this is RF (Radio Frequency) communication. As the distance increases, the radio signals become weaker. Distant signals can be affected by other radio waves or electromagnetic fields, which can reduce the quality of transmission. This communication technique causes communication interruptions over long trailer distances, considering that the tractor and trailer pairing length reaches approximately 16 meters. This prevents the system from being carried out in a healthy way.

[0008] Application No. US10300748 included in the state of the art describes the method and apparatus for vehicle TPMS localization. An example vehicle includes multiple TPMS sensors, a communication module, and a processor. The processor is configured to receive a localization request containing a tire position from a mobile device that is communicatively connected to the communication module.

[0009] Application No. TR2019 / 14674 in the state of the art is related to a system that enables information such as tank fullness, tire air pressure, battery fullness status from vehicles in large fleets consisting of a plurality of vehicles such as military fleets, etc. to be received remotely via LoRaWAN protocol and presented to the user.

[0010] When the systems in the state of the art are examined, there is no system that is compatible with all telematics systems, potentially compatible with CANBUS structures for existing OEM manufacturers, provides ease of installation with its practical installation structure on the valve, and provides instant data exchange via GPS with its expandable alarm and report structure. At this point, it is of great importance to design a system that uses the LoRa communication infrastructure, monitors the pressure and temperature of the tires, provides uninterrupted communication with GPS integration, and displays the monitoring results through a mobile application.

[0011] Summary and Objects of the Invention

[0012] The invention relates to an independently monitorable tire pressure monitoring system that measures the instantaneous pressure levels and temperature changes inside tires via valve sensors attached to the tires, transmits these through a centralized communication system, and eliminates data loss issues in long vehicles.

[0013] An object of the invention is to enable the TPMS system to easily adapt to each fleet monitoring system thanks to its independent fleet monitoring structure In this way logistics companies do not have to change the fleet management systems they have purchased with the existing investment.

[0014] Another object of the invention is to enable seamless communication with the last tire of the vehicle, regardless of the distance, without losing any information, using a single telematics system.

[0015] Another object of the invention is to solve the distance problem by using the LoRa communication infrastructure.

[0016] Another object of the invention is to monitor tire position with active fleet monitoring and to generate instant alarms in case of variable risk values. Another object of the invention is to enable connection with all telematics systems through GPS integration. Since the distance problem is solved, entire fleets or military vehicles that need to be monitored can be monitored on digital maps all over the world.

[0032] Detailed Description of the Invention

[0033] The invention relates to an independently monitorable tire pressure monitoring system that measures the instantaneous pressure levels and temperature changes inside tires via valve sensors attached to the tires, transmits these through a centralized communication system, and eliminates data loss issues in long vehicles.

[0034] Sensor module (10) consists of pressure sensor (11), temperature sensor (12), sensor board (13), battery (14), antenna (15), battery anode (16), battery cathode (17). The battery supplies power to the sensor module (10), and is disposed between the battery anode (16) and the battery cathode (17). There is a pressure sensor (11) and a temperature sensor (12) on the sensor board (13). The pressure sensor (11 ), installed on the tire valve head, continuously measures the air pressure inside the tire. The temperature sensor (12), installed on the tire valve head, continuously measures the surface temperature of the tire. Depending on the vehicle types, the PSI reading capacities of pressure and temperature sensors can be increased on the production line. In a preferred embodiment of the invention, the pressure sensor (11) has a processor infrastructure that can read 131 PSI and above, which is applied in heavy logistics transportation. The sensor module (10) is prepared in the 433.92mhz ASK-FSK module, which can read up to the last tire of the longest vehicle. Thanks to this feature, the probability of data loss over long vehicle distances will be very low. The sensors have a communication structure at a frequency of 433.92MHz or 868. mhz and initiate the communication process through the antennas inside. Each sensor has a battery (14) and this battery (14) supplies energy to the sensor by feeding the battery circuits.

[0035] The sensor board (13) receives pressure sensor (11 ) and temperature sensor (12) information and transmits this to the telematics reader via the transmitting antenna (15). This antenna (15) enables data to be transmitted to the telematics reader of the tractor, even in dense steel alloy environments. In environments with dense iron density, the DB of the antennas varies. However, the antennas produced generally broadcast standardly. In this regard, the processor in the system specifically separates the incoming signal.

[0036] The telematics reader (20) (Central Control Unit) receives pressure and temperature information regarding the wheels from the sensor board (13) through the receiving antenna thereon. The telematics reader (20) sends the data in accordance with the telematics or vehicle CANBUS communication protocol. The telematics reader (20) can send the information it receives from the sensor board (13) to the vehicle CANBUS line via IO outputs. The telematics reader (20) can easily share the data from the sensor board (13) with the telematics (vehicle monitoring system) with IO outputs. In this way, logistics fleet companies can supply this product as an optional product without changing their existing ATS structures. There is bluetooth on the telematics reader (20) to communicate with the application (30). The telematics reader (20) uses Lora and RFID communication frequencies. The pressure data is processed by the pressure sensor inside the board, the data is shared to the processor in the upper layer, and then the data is shared with the transmitter at the appropriate time intervals in the frequency range at which the processor requests the data to be sent to the transmitter.

[0037] The application (30) is executed on an electronic device, allowing the vehicle user to see the tire conditions on the vehicle via the interface. The application receives the data of the telematics reader (20) via bluetooth and presents it to the user.

[0038] In a preferred embodiment of the invention, the instant pressure levels and temperature changes in the tires are measured by means of valve sensors attached to the tires in tractors and trailers and transmitted through a central communication system. The sensors have a communication structure at a frequency of 433.92MHz and initiate the communication process through the antennas inside. Each sensor has a battery (14) and this battery (14) supplies energy to the sensor by feeding the battery circuits. For each axle, the tire is mounted on the valve top separately and thus an integrated system is created. The developed telematics reader (20) is located on the tractor and the mobile application (30) wakes up and activates all sensors one by one. The sensors report data on their current position on the telematics reader (20) in accordance with the regular R141 climate reconciliation. In the telematics reader (20), the incoming data is shared on demand to a telematics system or to the vehicle CANBUS line. In this way, system data can be monitored via web or mobile application (30) according to the end user's request. For the logistics sector, vehicle movement with accurate TPMS data means fuel savings. In this way, the aim is to provide an integrated monitoring system to logistics companies engaged in domestic and international transportation.
