Beidou User Computer System Applied to Vehicle Allocation

Abstract

The invention relates to a user machine system applied to vehicle allocation. The user machine system comprises a centralized vehicle monitoring management platform, a vehicle-mounted short message receiving and transmitting module and a vehicle-mounted positioning module, wherein a system director channel selection circuit consists of a D / A (digital / analog) conversion circuit, a radio frequency channel and an ARM (advanced RISC machine) processor; the vehicle-mounted short message receiving and transmitting module comprises a transmitting selection circuit; the vehicle-mounted positioning module comprises a receiving selection circuit; in case of selecting a military or civil mode, a decoder sends an instruction into the ARM processor; the instruction is sent to the transmitting selection circuits and the receiving selection circuits of all terminal machines through a Beidou satellite I by the radio frequency channel and antenna; a signal is sent into the ARM processor of a terminal through A / D conversion after being conditioned through the radio frequency circuit, so that an allocation mode can be selected. The user machine system applied to the vehicle allocation has the advantages that the system is low in use cost, administrates 50,000 terminals at most, can be connected with the Internet to conveniently acquire road condition information and weather information and is convenient for allocation and command.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a user machine system applied to vehicle allocation, which is applicable to both military and civilian dispatching modes. Background technique [0002] The previous vehicle command and dispatch system has the disadvantages of single application and poor compatibility, and can only be used for military or civilian use only. The military uses the Beidou No. 1 command aircraft as the command system, and the number of client terminals under its jurisdiction can only be about 100, and the use cost is high; the civilian use of the 3G network as the command system, although the use cost is very low, easy to use, the number of client terminals Huge, but the secrecy is too poor. So how can we combine the advantages of both, and overcome the shortcomings of both, so as to achieve the effect that the military and civilian command and dispatch modes are compatible? It needs to be re...
