example 1

[0046] The control method for the mobile user to remotely open the dome is as follows:

[0047] Such as figure 1 As shown, mobile information device description (MIDP) application program modules are installed in mobile phones supporting Java, and they are controlled by application management software (AMS) running in mobile terminals; effective users control programs through mobile phones, through HTTP The protocol connects to the remote WEB server and communicates with the servlet in the server.

[0048] Divide Web Server into four modules: Servlet module, parser module, JavaBeans component (reusable component) module, message sending module (SMS, socket or datagram); Servlet module is responsible for communicating with mobile phone users, receiving user requests, sending The server responds to the result and exchanges information with the parser module; the parser module is responsible for parsing the user request data received by the Servlet, and packages the returned inf...

[0068] Such as image 3 As shown, the temperature control method of the PUSH dome is as follows:

[0069] The telescope is a precision instrument with high requirements on the environment. When there is an abnormal situation in the telescope, it is necessary to inform the relevant personnel of the status of the telescope in time. Send the temperature of the LAMOST dome to the mobile phone of the designated person, and start the temperature processing program.

[0070] 1. Set the mobile phone to receive information in the server program, and register the network connection in the mobile phone;

[0071] 2. The local control system collects the temperature of the dome and transmits it to the server;

[0072] 3. The server encodes the temperature data in XML format, the format is as follows:

[0073]

[0074]

[0075]

[0076]

[0077]

[0078]

[0079] 4. The server pushes the encoded data to the designated mobile phone through the socket mode;

[0080] 5. When...

Abstract

The invention relates to a Java-based mobile control method for a telescope, used for HTTP connection between a mobile user and an appointed WEB server through a mobile terminal, and realizing real-time control of telescope shift. The method comprises the steps of: setting MIDPlet controlled by AMS operating in the mobile terminal and MIDP at the mobile terminal; describing the format of interaction between the terminal and the server by use of XML description protocol; resolving the protocol by use of NanoXML resolver; dividing the Web server into: Servlet module, resolver module, JavaBeans component module and massage sending module; realizing TCP / IP HTTP communication between the mobile terminal and the Web server in HttpConnection.POST way by use of Connector class in MIDP.

Description

technical field [0001] The invention relates to a method for controlling the movement of a telescope, in particular to a method for controlling the movement of a telescope based on Java. Background technique [0002] Large-scale astronomical telescopes are generally erected in places with relatively special geographical locations. Telescope engineers and technicians hope to be able to understand and control the status of the telescope "anytime, anywhere, and with them". The development of mobile communication technology makes this possible. [0003] The movement and remote control of existing telescopes are implemented based on short messages. Invention CN200510094716.3 discloses a wireless communication system for astronomical telescopes through GSM mobile phone short messages, and controls the telescope master control system through short messages. Due to the limitations of the SMS technology itself, the SMS-based method has the following disadvantages: the length of the S...
