Abstract
The invention discloses a civil aviation meteorology message converter which comprises a shell, a communication module and a coding converter. The shell is provided with a serial interface and a network interface. The communication module is provided with a UART module and a network module. The serial interface is connected with the coding converter through the UART module. The network interface is connected with the coding converter through the network module. The civil aviation meteorology message converter is flexible and convenient to deploy and is directly connected to a corresponding transmitting terminal computer in an international civil aviation telecommunication network, and after installation and configuration are finished, the device automatically completes coded format conversion and communication protocol conversion. Hardware link equipment between the transmitting computer and the international civil aviation telecommunication network can be effectively reduced, flexibility is high, the failure rate is low, and hardware cost and later-period maintenance are effectively reduced.
Description
Technical field
The invention belongs to the meteorological automatic Observation field of civil aviation, it relates to the meteorological message transmodulator of a kind of civil aviation.
Background technology
Airport weather report comprises two types: customary weather report (METER) and special weather report (SPECI). Customary weather report sends once every one hour or half an hour. This kind of report load states the meteorologicelements that at the appointed time inherent airport observes. When the weather conditions on airport worsen significantly or take a turn for the better, except customary weather report, airport meteorology can send special weather report. These important Changes in weather comprise surface wind, visibility meter, the obvious change of the height of cloud base, or boisterous appearance or disappearance etc.
International Civil Aviation telegram uses two kinds of coding form: ITA2 to encode and IA5 coding simultaneously, and computer software generally only identifies IA5 coding at present. Airport computer application software of transmitting messages correctly to be processed civil aviaton's code message, it is necessary to is changed by message coding, so that computer application software of transmitting messages can identify association message, processes to carry out, store.
International Civil Aviation turns report machine provides serial line interface and computer interactive, but serial line interface is not supported in most computers standard configuration now, thus civil aviation turn the general computer of transmitting messages of report machine and airport cannot directly communication. Therefore, when sending and receive message, it is necessary to provide the conversion module of serial line interface and computer network interface, to complete communication. Current operation is wasted time and energy, and needs a kind of simplicity that can carry out badly and changes the device of coding with interface fast.
Summary of the invention
For solving the problem, the present invention by the following technical solutions:
The meteorological message transmodulator of a kind of civil aviation, comprise housing, communication module and code conversion device, housing is provided with the serial line interface for connecting International Civil Aviation telecommunications network and the network interface for connecting computer of transmitting messages, and communication module and code conversion device are arranged on enclosure interior; Communication module is provided with UART module and network modules; Code conversion device inside is provided with code conversion program, for the message of input carries out the mutual conversion between ITA2 coding and IA5 coding; Serial line interface is connected with code conversion device by UART module, and network interface is connected with code conversion device by network modules.
Further improvement, described housing is provided with 16 serial line interfaces.
Further improvement, described network modules is network interface card.
Compared with prior art, the present invention has the following advantages:
1. disposing flexible, the terminal computer of transmitting messages that to be directly connected in AFTN corresponding, after completing Install and configure, device completes the conversion of coding form and the conversion of communications protocol automatically.
2. effectively reducing the hardware link equipment transmitted messages between computer and International Civil Aviation telecommunications network, handiness height, failure rate rate is low, effectively reduces hardware costs and later maintenance.

Fig. 2 is inner work-based logic figure.
Embodiment
The meteorological message transmodulator of a kind of civil aviation, comprise housing, communication module and code conversion device, housing is provided with the serial line interface for connecting International Civil Aviation telecommunications network and the network interface for connecting computer of transmitting messages, and communication module and code conversion device are arranged on enclosure interior; Communication module is provided with UART module and network modules; Code conversion device inside is provided with code conversion program, for the message of input carries out the mutual conversion between ITA2 coding and IA5 coding; Serial line interface is connected with code conversion device by UART module, and network interface is connected with code conversion device by network modules.
As shown in Figure 1, arrow represent data stream to, message is sent to the meteorological message transmodulator of civil aviation by the mode of UDP communication by computer of transmitting messages, and civil aviation meteorological message transmodulator is sent to International Civil Aviation telecommunications network by serial communication after being changed by message coding form. Numeral 1 and N above arrow represent: when computer of transmitting messages sends information to International Civil Aviation telecommunications network, a computer of transmitting messages is sent to the meteorological message transmodulator of a civil aviation, and the multiple turns of report machines that message can be sent in International Civil Aviation telecommunications network by a meteorological message transmodulator of civil aviation; When International Civil Aviation telecommunications network sends information to computer of transmitting messages, being then that an International Civil Aviation turns report machine message is sent to the meteorological message transmodulator of civil aviation, message can be sent to multiple stage computer by a meteorological message transmodulator of civil aviation
As shown in Figure 2 (for ground being described clearly, the input and output process of communication module is separately represented by this figure), wherein " UART " represents universal asynchronous serial transceiver module, " NET " represents Network Interface Module, and RS232, RS422, RS485 represent three kinds of communications protocol that serial line interface provides. Computer of transmitting messages during use is connected by the meteorological message transmodulator of network interface and civil aviation, and the meteorological message transmodulator of civil aviation is connected to International Civil Aviation telecommunications network (AFTN) by serial line interface. When computer of transmitting messages sends information, IA5 coded data is sent to transmodulator by netting twine with UDP communication, converter inside treater will receive data and carry out code conversion, by IA5 code conversion be ITA2 coding, and by serial line interface by process after data be sent to International Civil Aviation telecommunications network (AFTN). Transmit messages computer receiving data time, International Civil Aviation telecommunications network (AFTN) sends IA5 coded data and ITA2 coded data to transmodulator by serial line interface, ITA2 code conversion is IA5 coding by converter inside treater, then is sent to, with UDP communication, computer of transmitting messages by network interface.
Embodiment is for illustration of the present invention, but is not used for limiting the scope of the invention, and every any simple modification, equivalent variations and modification done by following instance according to the technical spirit of the present invention, all still belongs in the scope of technical solution of the present invention.
