Embodiment Construction

[0020] now attached Figures 1 to 2 The present invention is described in further detail

[0021] The present invention is realized in figure 1 The hardware platform includes antenna, Beidou equipment, ARM platform, electrical characteristic protection circuit and Beidou RD smart card.

[0022] After the Beidou equipment receives the satellite outbound information through the antenna, it transmits it to the ARM platform through the cable. The ARM platform re-encodes the information that needs to be processed by the Beidou RD smart card according to the Beidou RD smart card technology protocol and sends it to the Beidou RD smart card, and receives the information processed by the Beidou RD smart card, and forwards it to the Beidou device after decoding; at the same time, the Beidou device uses the Beidou RD smart card The processed information realizes the inbound function of active communication and positioning.

[0023] The hardware ARM platform of the present invention se...

Abstract

The invention relates to the field of satellite navigation, in particular to a Beidou RD intelligent card remote reading method, which does not need any Beidou equipment assistance and independently uses an ARM to realize Beidou RD intelligent card remote reading technology. The Beidou equipment has common message communication, positioning and navigation functions, a Beidou RD intelligent card and the Beidou equipment need to be installed together to be used outdoors, but the lowest normal working temperature of the Beidou RD intelligent card is-20 DEG C, and the Beidou RD intelligent card cannot be used frequently in northern winter. A technology which can separate the Beidou RD intelligent card from Beidou equipment and can enable the Beidou equipment to realize remote operation of theBeidou RD intelligent card is urgently needed to solve the problem. Therefore, the Beidou RD intelligent card remote card reading technology invented by analyzing the physical characteristics and theinstruction characteristics of the Beidou RD intelligent card has very important significance.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a technology for remotely reading a Beidou RD smart card by independently using an ARM platform without the assistance of any Beidou equipment. Background technique [0002] The "Beidou-2" satellite navigation system is a global satellite positioning and navigation system independently developed by my country, which provides a full range of global navigation and positioning services by sea, land and air. Among them, RDSS mainly integrates the two functions of Beidou RDSS positioning and RDSS short message, and Beidou RD smart card is the key to open these two functions. The Beidou RD smart card can realize the Beidou two-way short digital message communication, which can transmit 140 characters of information at a time, and can also locate and display the position of the publisher. In oceans, deserts and wild places where there is no communication and network, you can locate ...
