Abstract

The invention discloses a DSP-based indoor inertial navigation system. The current navigation sensing methods used by wheeled sports cars comprise visual, photoelectric, ultrasonic, odometers and thelike so that the wheeled sports cars are relatively prone to be disturbed by the external environment and cannot meet the needs of the vast market. The DSP-based indoor inertial navigation system consists of a wheeled car (1) and a PC terminal (2), wherein the wheeled car is internally provided with a digital compass (3), an accelerometer (4), a gyroscope (5), a core plate and a driving plate; thecore plate is connected with the digital compass, the accelerometer and the gyroscope; the core plate is connected with the PC terminal through a WIFI signal; and the driving plate is connected withthe core plate. The invention is applied to the DSP-based indoor inertial navigation system.

Description

Technical field: [0001] The invention relates to a DSP-based indoor inertial navigation system. Background technique: [0002] Wheeled remote-controlled robots have been used in some dangerous indoor areas such as earthquakes and fires for rescue and detection, or to perform anti-terrorism tasks. Because there are many unknown factors in these special environments, and there is no GPS signal indoors, people have to rely on advanced science and technology and instruments to obtain the navigation information of the remote control robot car. However, the current navigation sensing methods mainly used by wheeled sports cars include vision, photoelectricity, ultrasound, odometer, etc., which are relatively easy to be interfered by the external environment and cannot meet the needs of the general market. [0003] However, the inertial navigation equipment is placed in the carrier, does not rely on external information, does not radiate energy to the outside world, and is not easi...
