Detailed Description
The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for the purpose of understanding and controlling the technical solutions of the present invention, so as to define the protection scope of the present invention more clearly.
The utility model discloses a positioning device for an underground tunnel region of a tramcar, which is combined with a figure 1 and comprises a ground component, wherein the ground component is composed of an induction coil, a rectifier, a system clock, a signal encoder, a demodulator and an amplifier and is arranged between tracks, and the ground component is connected with a vehicle-mounted component arranged on a tramcar body.
The vehicle-mounted assembly comprises a signal receiving and transmitting assembly consisting of a radio frequency power amplifier and a vehicle-mounted antenna, and the signal receiving and transmitting assembly is in signal connection with the carrier frequency power amplifier. The two signal transceiving components are arranged and respectively arranged at the head of the tramcar and the bottom of the tail of the tramcar. The induction coil is connected with a vehicle-mounted antenna of the tramcar through a radio frequency signal, and the rectifier is connected with the induction coil through a signal. The system clock is in signal connection with the demodulator and the signal encoder, the demodulator is in signal connection with the amplifier, and the amplifier is in signal connection with the induction coil. The rectifier is in signal connection with the system clock and the signal encoder. The decoder is connected with the control center through an Ethernet switch.
The following brief description of the signal transmission principle of the present invention:
the induction coil is used for receiving carrier frequency energy transmitted by the vehicle-mounted antenna and feeding fixed data back to the vehicle-mounted antenna; the rectifier converts the received carrier frequency energy into direct current to enable the ground component to enter a working state; after obtaining the working voltage, the system clock sends clock information to the signal encoder and the demodulator; the encoder reads information stored in the system and sends the information to the demodulator, the demodulator demodulates the data, and the amplifier sends the processed position information to the vehicle-mounted antenna through the induction coil.
The utility model relates to data transmission equipment based on an electromagnetic coupling induction principle, which realizes vehicle-ground two-way communication by utilizing wireless induction. The ground component is used for sending fixed and unchangeable data and providing fixed parameters of the line, such as kilometers marks, tunnel gradient, interval allowed driving speed and other various information. The ground component is in a dormant state at ordinary times, and when the tramcar receives carrier frequency electromagnetic energy transmitted by the vehicle-mounted antenna through the ground component, the carrier frequency electromagnetic energy is converted into electric energy to enable the tramcar to start working, and data stored in the component in advance is continuously and circularly transmitted out until the tramcar drives away. And the control center can determine the accurate position of the tram on the line according to the received information.
In addition to the above embodiments, the present invention may have other embodiments, and any technical solutions formed by equivalent substitutions or equivalent transformations are within the scope of the present invention as claimed.
