Problems solved by technology

However, this type of fixed-format data cannot contain specific character sequences, which requires users to preprocess the data
In addition, for a specific device platform, the data length has a certain byte limit, which means that corresponding to larger data users must deal with operations such as data framing and framing

Embodiment Construction

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035]In an embodiment of the present invention, the Beidou short message platform for the station site in the Lenghu area adopts the Beidou short message communication equipment independently developed and produced by Shanghai Beizhe Industrial Automation Co., Ltd., which can support the maximum single data 77 bytes of data telegram transmission. Since the platform provides Beidou communication cards, radio frequency circuits and antennas, for ordinary users, the operation of sending short messages is to send data in a fixed format to the port of the device, and the operation of receiving short messages is to read from the port of the device Fixed format data. However, such fixed-format data cannot contain specific character sequences, which requires users to preprocess the data. In addition, the data length is limited to 77 bytes, which means that users corre...

Abstract

The invention discloses a telescopic remote data transmission and control method based on Beidou short message. It sets a DT flag bit by designing a protocol, escapes special characters existing in specific data, and adopts framing for larger data blocks. The framing mechanism implements the necessary error control and congestion control mechanism for the actual transmitted data, and successfully realizes the function of transmitting telescopic remote data using the Beidou short message RDSS‑DTU. The application of the data transmission method of the present invention enables users to transmit short messages containing specific characters, and the returned observation data continues to be normal, thereby ensuring the reliability of communication.

Description

technical field [0001] The invention belongs to the technical field of observation data transmission and control, and in particular relates to a telescope remote data transmission and control method based on Beidou short messages. Background technique [0002] At present, some scientific research projects need to build unattended small observation stations to collect meteorological and other data around candidate astronomical observatories in unmanned areas, and it is necessary to realize that the observation data on the site can be transmitted back to the observatory headquarters, and the headquarters can Remote control of on-site observation tasks. Due to the uninhabited area in the hinterland of the Qinghai-Tibet Plateau, there are currently no conventional communication methods such as mobile communication and optical fiber communication, and the environmental parameters of the candidate astronomical sites are evaluated in turn. This process requires uninterrupted collec...
