Abstract

The invention relates to emergency positioning equipment based on first-generation Beidou and second-generation Beidou. The emergency positioning equipment is composed of a host and handheld inquiry equipment, wherein the host comprises an antenna unit, a first-generation Beidou RDSS (Radio Determination Satellite Service) module, a second-generation Beidou RNSS (Radio Navigation Satellite Service) module, a control module, a UPS (Uninterrupted Power Supply), an EEPROM (Electrically Erasable Programmable Read-Only Memory), a data interface and a power interface; the UPS module and a protective shell are used for reducing the voltage to adapt to the low temperature and low air pressure environment in the air; when an emergency occurs, the UPS automatically switches external power to internal battery power; and the host sends position information calculated by the second-generation Beidou to the ground handheld inquiry equipment through a short message of the first-generation Beidou. The emergency positioning equipment has the advantages that the positioning is accurate, the concealment is good, the equipment is not influenced by distance, the shortcoming that a disturbed wartime GPS (Global Positioning System) cannot be used is avoided, and the handheld inquiry equipment can control the host to work through a satellite and master the information of the host at any time.

Description

A kind of emergent positioning equipment based on a Big Dipper generation and Beidou II
Technical field
Invention relates to a kind of emergent positioning equipment, particularly a kind of emergent positioning equipment based on a Big Dipper generation and Beidou II.
Background technology
The equipment such as some radar domestic, utilizes balloon for carrier, is raised to by radar in the air, to increase EFFECTIVE RANGE at present.Aloft uncontrollable factor is many, and when the hawser of captive balloon surprisingly disconnects, balloon can be floating with air-flow, pick-up point and surrounding enviroment of landing uncertain, very large difficulty is caused to the search-and-rescue work of balloon.
Summary of the invention
In view of prior art Problems existing, invention adopts Beidou II RNSS system accuracy high, Big Dipper generation RDSS can directly and satellite communication and by such environmental effects minimum, location time service function under providing a kind of feasible system platform normally to work and the emergent positioning equipment of the reliable feedback function of case of emergency upper/lower positions information, concrete technical scheme is, a kind of emergent positioning equipment based on a Big Dipper generation and Beidou II, be made up of main frame and hand-held inquiry unit, it is characterized in that: main frame comprises antenna element, Big Dipper generation RDSS module, Beidou II RNSS module, control module and ups power, EEPROM, data-interface, power interface, in antenna element, LNA LNA1 is connected with Beidou II RNSS module by radio-frequency cable, dumb antenna is connected by the LNA LNA2 of radio-frequency cable with Big Dipper generation RDSS module, passive transmitting antenna is connected by the power amplifier PA of radio-frequency cable with Big Dipper generation RDSS module, control module is connected with Big Dipper generation RDSS module and Beidou II RNSS module by RS232 serial ports, be connected with the management of charging and discharging of battery by SMbus bus, be connected with EEPROM by I2C bus, externally exported by data-interface RS485, the DC-DC power source part of ups power module is connected with modules by power lead, the additional containment vessel of ups power module carries out step-down process, to adapt to high aerial low-temperature and low-pressure environment, when there is case of emergency, externally fed is switched to internal battery powers by ups power automatically, the positional information that RNSS calculates by main frame, ground hand-held inquiry unit is sent to by the short message of Big Dipper generation RDSS.
The technique effect of invention is accurate positioning, good concealment, not by the impact of distance, avoid wartime GPS disturbed and the drawback that cannot use, hand-held inquiry unit by the work of satellite main control system, and can grasp the information of main frame at any time.
Accompanying drawing explanation
Fig. 1 is that main frame of the present invention forms block diagram.
Embodiment
One based on the emergent positioning equipment of a Big Dipper generation and Beidou II as shown in Figure 1, be made up of main frame and hand-held inquiry unit, main frame comprises antenna element, Big Dipper generation RDSS module, RNSS module, control module and ups power, EEPROM, data-interface, power interface, in antenna element, LNA LNA1 is connected with Beidou II RNSS module by radio-frequency cable, dumb antenna is connected by the LNA LNA2 of radio-frequency cable with Big Dipper generation RDSS module, passive transmitting antenna is connected by the power amplifier PA of radio-frequency cable with Big Dipper generation RDSS module, control module is connected with Big Dipper generation RDSS module and Beidou II RNSS module by RS232 serial ports, be connected with the management of charging and discharging of battery by SMbus bus, be connected with EEPROM by I2C bus, externally exported by data-interface RS485, the DC-DC power source part of ups power module is connected with modules by power lead, the additional containment vessel of ups power module carries out step-down process, to adapt to high aerial low-temperature and low-pressure environment, when there is case of emergency, externally fed is switched to internal battery powers by ups power automatically, the positional information that Beidou II RNSS calculates by main frame, ground hand-held inquiry unit is sent to by the short message of Big Dipper generation RDSS.Wherein RNSS adopts Beidou II RNSS locating module, and RDSS adopts Big Dipper generation RDSS communication module, takes full advantage of that Beidou II system positioning precision is high, Big Dipper generation RDSS can directly and satellite communication and the advantage being subject to such environmental effects minimum.
