Recently, wireless modules have been applied to smart bus management. They can provide location information under different circumstances, as well as transmit information related to onboard communication systems and in-vehicle payment transactions. They also have Wi-Fi, Bluetooth, and high-speed 4G internet capabilities that are backwards compatible with 3G, making it easy to access vehicle data records.
The positioning module of the new smart bus is equipped with acceleration and gyro sensors, which further enhance the accuracy of its location. The module can be connected to the backend system through high-speed LTE to transmit information related to onboard communication systems and in-vehicle payment transactions. With built-in three-dimensional inertial sensors coupled with location data, the wireless module can achieve precise positioning even in environments with weak satellite signals, such as urban areas with tall buildings, underground parking lots, or tunnels.
The wireless module used for fleet management and payment systems provides super-fast 150 Mbps 4G speeds and is backwards compatible with 3G. This high-speed connectivity not only allows for fast and reliable payment processing, but also enables streaming of video content from internal or external car cameras, simultaneously supporting client and access point operations. Therefore, this module can serve as a wireless hotspot, as well as a client device for another Wi-Fi access point.
The wireless module technology is developing rapidly and continuously exploring new fields. The application of wireless module technology to smart bus systems makes bus operation and management more convenient and efficient, truly realizing real-time and reliable performance.
Wireless modules have been widely used in automatic meter reading and charging systems for water, electricity, gas, and heating, smart wireless PDA terminals, wireless queueing devices, anti-theft alarms, smart cards, medical and electronic instrument automation control, smart teaching equipment, intelligent household appliances and lighting control, wireless crane scales, and wireless electronic scales. In terms of power supply, the module uses a low voltage power supply method, and users do not need to write settings or transmission programs during use. With small size and low cost, wireless modules are convenient for mass use and are rapidly developing in the field of wireless communication.
The role of wireless modules is closely related to their application areas and functional settings, including transmission, control, monitoring, matching and other functions. By configuring the pinouts of the wireless module and programming the software, the transmission and modulation methods can be altered.
In addition, the built-in watchdog of the wireless module can monitor and ensure reliable operation of data transmission to avoid accidents.
