Description

  The present invention relates to a method for initial setting of a satellite terminal using an orbiting satellite, and more particularly to an initial setting method for a satellite terminal that performs initial setting by radio.

  A satellite terminal that receives a data collection service and a positioning service using an orbiting satellite needs to set a frequency, a transmission interval, a service to be operated, and the like before starting operation. FIG. 4 is a system configuration diagram showing a conventional system for initial setting of a satellite terminal. In FIG. 4, a PC or a dedicated writing device 30 is connected to the external serial port of the satellite terminal 20 via a writing serial cable 35. The satellite terminal 20 is set to the initial setting mode and the external serial port becomes active.

  Next, the data is written according to the initial setting writing menu on the screen of the PC or the dedicated writing device 30, and the written data is transmitted to the satellite terminal 20. When the data is normally written, the satellite terminal 20 transmits a normal write signal to the PC or the dedicated writing device 30, and the power is turned off after the transmission is completed. When the PC or the dedicated writing device 30 confirms the normal writing signal, the serial cable is disconnected and the initial setting is completed. During operation, the data collection device 40 is connected to the same external serial port connector via the user data transfer cable 45 and operates.

  FIG. 5 is a flowchart showing a conventional initial setting sequence. The PC or dedicated writing device 30 and the satellite terminal 20 are connected via a writing serial cable, and the respective power supplies are turned on (step 400). The satellite terminal 20 is set to the initial mode (step 410). As a result, the external serial port of the satellite terminal 20 becomes active and enters a receiving state in which data from the PC or the dedicated writing device 30 is awaited (steps 420 and 430). When the data is received, the data corresponding to a predetermined area of the EEPROM is written and an initial setting value is set (step 440). When the writing is normally performed, the respective power sources are turned off and the initial setting is finished (step 450).

When the satellite terminal 20 is operated alone, the burden of cable connection exchange in the initial setting is not a big problem. However, when used as a communication means of the observation system, the satellite terminal 20 is incorporated in the observation equipment. Therefore, if trouble occurs after initial setting and the setting is reset, or if the setting is changed after operation, the observation equipment must be partially disassembled and the setting burden increases. . In particular, in the case of marine observation equipment or communication means such as a buoy, a larger burden is required because it is sealed inside the waterproof case. Patent Document 1 describes that a squelch control signal of a wireless device is written and changed by a PC.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a satellite terminal initial setting method for performing initial setting of a satellite terminal using an orbiting satellite by radio. .

Initial setting of the satellite terminal of the invention is a method of initializing a satellite terminal for initialization of the satellite terminal for measuring position of the data collection by using orbiting satellites, the satellite terminal and initialization radio The satellite terminal has control means, storage means, and transmission / reception means, and the initial setting radio has control means, storage means, transmission / reception means, and display means, and the power of the satellite terminal is turned on. Then, the control means of the satellite terminal checks the initial setting state by the initial operation program stored in advance in the storage means, and sets the transceiver to active if the initial setting is not set, and sets the initial setting radio When the initial setting radio is turned on and the initial setting radio is powered on, the control means of the initial setting radio stores the initial setting program stored in advance in the storage means. A step of displaying an input screen for inputting initial setting data on the display means, and a step of transmitting the input initial setting data to the satellite terminal by the transmission / reception means when the initial setting data is input to the input screen; When the initial setting data is received via the transmission / reception means, the control means of the satellite terminal stores the initial setting data in the storage means, and when the initial setting data is normally stored in the storage means, When the initial setting data is not normally stored in the storage means, a write error signal is sent to the initial setting radio via the transceiver. The step of transmitting and waiting for the reception of the initial setting data from the initial setting radio again, and the control means of the initial setting radio are the satellite terminals via the transmission / reception means Upon receiving the Luo write end signal, it terminates the operation to stop the transmission of the initial setting data, upon receiving a write abnormal signal, and having the steps of: transmitting a re-initialization data. The condition is that the wireless output does not exceed the legal output of the Radio Law.

  In the satellite terminal initial setting method of the present invention, when the satellite terminal is powered on, the control means of the satellite terminal starts checking the initial setting state, and if the initial setting is not completed, the operation mode It has the step which prohibits entering.

  According to the present invention, since the initial setting of the satellite terminal using the orbiting satellite can be performed wirelessly during operation, the setup of the system for the initial setting is facilitated, and the device can be changed even when the setting is changed during operation. It becomes possible to change without contact from the outside without disassembling.

  Embodiments of a satellite terminal initial setting method according to the present invention will be described with reference to the drawings. FIG. 1 is an initial setting system diagram showing a system to which a satellite terminal initial setting method according to the present invention is applied. The satellite terminal 20 has control means, storage means, and transmission / reception means, and the initial setting radio 10 has control means, storage means, transmission / reception means, and display means. The satellite terminal 20 receives the initial setting data transmitted from the initial setting radio 10 and writes this data in the EEPROM of the storage means. When the writing is completed normally, a write end signal is transmitted to the initial setting wireless device 10, and when the writing is not normally performed, a write abnormality signal is transmitted, and the initial setting data is retransmitted. The initial setting wireless device 10 may control a general PSK modulator, a signal generator, and an antenna by a PC that operates according to an initial setting program described below, instead of a dedicated device for initial setting.

  FIG. 2 is a flowchart showing the initial setting method of the satellite terminal according to the present invention. When the power of the satellite terminal 20 is turned on, the control means of the satellite terminal checks the initial setting state by the initial operation program stored in advance in the storage means (Step 200, Step 210). If the initial setting has not been made, the operation mode input is prohibited and the initial setting mode is entered, the transceiver is set to active, and reception of initial setting data from the initial setting radio 10 is awaited (steps 220 to 250). When the control means of the satellite terminal receives the initial setting data via the transmission / reception means, the initial setting data is stored in the EEPROM of the storage means (step 260). If the initial setting data is not normally stored in the EEPROM, a write error signal is transmitted to the initial setting radio 10 via the transceiver, and the reception of the initial setting data from the initial setting radio 10 is awaited again (step 270, Step 295). When the initial setting data is normally stored in the EEPROM, a write end signal is transmitted to the initial setting radio 10 via the transceiver, and the initial setting is completed (steps 270 to 290). If the initial setting data has already been written in step 210, the process proceeds to step 280 and step 290, and the operation mode can be entered.

  FIG. 3 is a flowchart showing an initial setting method of the initial setting radio of the present invention. When the power of the initial setting wireless device 10 is turned on, the control means of the initial setting wireless device 10 displays the input screen for inputting the initial setting data according to the initial setting program stored in advance in the storage means. It is displayed on the means (step 300, step 310). When the initial setting data is input to the input screen, the input initial setting data is transmitted to the satellite terminal 20 by the transmission / reception means (step 320, step 330). When receiving the write end signal from the satellite terminal 20 through the transmission / reception means, the control means of the initial setting wireless device 10 stops the transmission of the initial setting data and ends the initial setting operation (steps 340 to 360). When the write abnormality signal is received, the initial setting data is transmitted again (steps 350 and 330).

  As described above, according to the present invention, the initial setting and operation status confirmation of a satellite terminal using an orbiting satellite can be performed without using a dedicated initial setting radio using the frequency and modulation method of the operation service. Since it can be performed using a general PC, PSK modulator, signal generator, and antenna, it is easy to set up the system for the initial setting, and even when the setting is changed during operation, the system can be externally disassembled. It can be changed without contact, and the production and operation of satellite terminals can be made more efficient.
