Bus-mounted intelligent terminal based on Beidou/GPS compatible location

Abstract

The invention provides a bus-mounted intelligent terminal based on Beidou / GPS compatible location. The bus-mounted intelligent terminal comprises a first subsystem based on a CPU and a second subsystem based on an MCU. The first subsystem further comprises a BD2 / GPS navigation module, a video / audio processing module, a communication module, an identity recognition module and a power supplying and power source management module, wherein the BD2 / GPS navigation module, the video / audio processing module, the communication module, the identity recognition module and the power supplying and power source management module are connected with the CPU, the BD2 / GPS navigation module is used for receiving navigation signals of a Beidou secondary navigation system and a GPS to achieve dual-system compatible location, the video / audio processing module is used for taking charge of coding-decoding processing on video signals and audio signals, the communication module is used for being in voice and data communication with a wireless communication network and building a wireless communication linkage through a WiFi or a Bluetooth, and the power supplying and power source management module is used for managing a power source system. The second subsystem further comprises an OBD data acquisition module, a one-card module, a bus station broadcaster module, an external interface module and the like, wherein the OBD data acquisition module, the one-card module, the bus station broadcaster module, the external interface module and the like are connected with the MCU, the OBD data acquisition module is used for acquiring vehicle status information through a vehicle body bus, and the MCU of the second subsystem is controlled by the CPU of the first subsystem.

Description

technical field [0001] The invention relates to a Beidou / GPS compatible positioning as the basis, in particular to a bus-mounted intelligent terminal based on the Beidou / GPS compatible positioning. Background technique [0002] Compared with developed countries such as Europe, America and Japan, the development of my country's public transportation industry is still relatively slow. Moreover, the intelligent level of bus operation has not kept up, and most of them still follow the old manual-based operation system. [0003] In recent years, my country's intelligent public transport system has begun to flourish. Most of the first- and second-tier cities in my country and some third-tier cities have installed vehicle tracking and dispatching systems on some bus lines. GPS positioning equipment is installed on the vehicles, which can realize real-time monitoring of vehicles and two-way communication between vehicles and monitoring centers. [0004] Although my country has ach...

AI Technical Summary

Problems solved by technology

[0006] 2. Public information is not shared, forming a de facto information island, each device communicates independently, and communication costs are high

[0007] 3. The vehicle-mounted intelligent terminal has poor scalability, cannot effectively play the role of data aggregation and transmission, and cannot be closely connected with other devices
