Description

1 TARIFF SUPERVISOR AREA NETWORK SYSTEM TECHNICAL AREA 5 The invention relates to a controller area network (CAN) system for vehicles. PREVIOUS TECHNIQUE To enable data communication between various electronic components found in vehicles. For this purpose, Controller Area Network (CAN) systems are widely used. It is used as such. CAN systems, especially engine control units (ECUs), instrument panels, and air conditioning systems. Fast and efficient switching between units such as systems and controls on the steering wheel. It provides a reliable means of communication. Current CAN systems typically transmit data over twisted-pair copper cables. However, this transmission structure has a certain distance limit. Standard 20 When the CAN cable length exceeds 40 meters, signal attenuation, interference, and data loss can occur. Problems such as loss arise. While current designs for public transport vehicles fall below this limit, The longer bus, tram, or articulated vehicle models to be produced will have CAN line 25. The signal length is expected to increase. In this case, the signal of existing systems Its inability to maintain its integrity constitutes a significant technical problem. Current techniques use signal amplifiers or repeaters to address this problem. These solutions are available; however, these solutions generally add cost and complexity to the system. 30 and introduces a delay. Also, electromagnetic interference (EMI) causes...

BRIEF DESCRIPTION OF THE FIGURES Figure 1 shows a schematic representation of the Controller Area Network (CAN) system, which is the subject of the invention. The appearance is given. DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the subject of the invention is the controller area network (CAN) system (10) only will not create any limiting effect on a better understanding of the subject This is explained with examples. 3 The invention enables signal transmission even when the length of a vehicle exceeds 40 meters. The invention relates to a controller area network (CAN) system (10) in which the quality is maintained. Within this scope, the controller area network (CAN) system (10) has at least one fiber between its two ends. An optical cable (80) is integrated. For this purpose, a first CAN Network device is used. (30) and a second CAN Network device (60) are used. 5 A detailed explanation of a first CAN line (40) is given by connecting it to the vehicle's console or steering wheel. at least one control component (20) located in the region (e.g. radio controller, instrument panel or steering wheel keypad) and first CAN Network device (30) It extends between them. 10 A second CAN line (70) connects to at least one electronic device located in other parts of the vehicle. It extends between the control unit (ECU) and the second CAN Network device (60). Fiber optic cable (80) connects the first CAN Network device (30) to the second CAN Network 15 The device (60) extends between the devices and the CAN data is transmitted as an optical signal between these two devices. It ensures that it is transmitted in this way. The first CAN Network device (30) and the second CAN Network device (60) are electrical CAN devices. Converting the signal to an optical signal and converting the optical signal back to CAN format 20 It has various functions. In this way, since data is transmitted over long distances as a light signal, the signal No loss or electromagnetic interference occurs. Due to the fragile nature of fiber optic cable (80), the cable should be installed in the system. Protective covers or channel structures that secure to the vehicle body can be used. Thanks to the aforementioned configurations of the invention, depending on the length of the vehicle Even if the system length exceeds 40 meters, the data transmission speed does not decrease; the signal remains at 30. Its integrity is preserved, and the impact of electromagnetic interference is minimized. 4 In these respects, the invention offers a longer lifespan compared to existing copper-based CAN lines. It provides reliable communication over long distances and acts as a controller in long vehicle designs. This allows the area network (CAN) system (10) to operate smoothly. The scope of protection of the invention is set out in the claims attached hereto and is strictly limited to these 5. The detailed explanation cannot be limited to the examples given. Because in technology... A specialist, without deviating from the main theme of the invention, will do what is described above. It is clear that similar structures can emerge in light of this. 5 REFERENCE NUMBERS GIVEN IN THE FIGURES Controller area network (CAN) system Control component First CAN network device 5 40 First CAN line 50 Electronic control units 60 Second CAN network device 70 Second CAN line 10 80 Fiber optic cables
