Abstract

PURPOSE:To specify a terminal by a keyword code string and to freely close a power source in a remote terminal from a host device by adding a remote power source enter function to a circuit adapter. CONSTITUTION:The titled device is a remote power source closing device installed on the circuit adapter 2 connected to the host device 21, and has a circuit control part 2 connected to a transmission line 11, a terminal connection part 3 connected to the terminal equipment 22, a code detection part 4 to detect a specific code string encoded by the circuit control part 2, and a power source control part 5 which is operated by the code detection part 4 and controls a terminal equipment power source 23. The code string encoded by the circuit control part 2 is also transmitted to the code detection part 4. With a call code string, etc., as a keyword in terms of transmission procedure, the code detection part 4 detects the code string, and when it detects the specific code string, it closes the power source of the terminal equipment power source 23 through the power source control part 5. Since the power source of the circuit adapter 1 is independently supplied from the terminal equipment power source 23, the circuit adapter 1 always supervises the code string outputted by the host device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote power-on device, and more particularly to a remote power-on device for controlling the PIc source of a terminal device connected online.

[Conventional technology]

Conventionally, remote power-on devices for online terminal devices utilize a carrier signal that is used to transmit signals through a transmission line, separate the signal using a modem, and turn on the power of the online terminal device using the carrier signal. was.

[Problem that the invention seeks to solve]

The conventional remote power-on device described above automatically powers on other online terminal devices connected under the same transmission path in a multi-drop manner, so it is not possible to remotely power on only a specific online terminal device. There are drawbacks.

[Means for solving problems]

The remote power-on device of the present invention includes a line control unit connected to a host device via a transmission path, a code detection unit that detects a specific code string from a code string obtained by the line control unit encoding a signal on the transmission path. The power control unit includes a power control unit that powers on a terminal device corresponding to the specific code string when the code detection unit detects the specific code string.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the invention. In FIG. 1, this embodiment is a remote power-on device installed in a line adapter 1 connected to a host device f21, and connected to a line control unit 2 connected to a transmission path 11 and a terminal device 22. It includes a terminal connection section 3, a code detection section 4 that detects a specific code string encoded by the line control section 2, and a power supply control section 5 that is operated by the code detection section 4 and controls a terminal device power supply 23.

The line control unit 2 is connected to a host device 21 via a transmission line 11. This line control unit 2 converts the signal transmitted via the transmission line 11 into code data, and sends it to the terminal device 22 via the terminal connection unit 3 and the line adapter data bus 12 as a code string. The code string encoded by the line control section 2 is also sent to the code detection section 4. The code detection section 4 detects a code string using a calling code string or the like in the transmission procedure as a keyword, and when a specific code string is detected, powers on the terminal device power supply 23 via the power control section 5. Since the line adapter 1 itself is supplied with power independently from the terminal device power supply 23, the line adapter 1 can always monitor the code string output from the host device.

As a result, the host device 21 is connected to a plurality of line adapters 11 to 1m as shown in FIG.
Turn on the power of any terminal device using the call code etc. corresponding to the keyword as a keyword. For example, in the host device 21, if the call code is keyword 1, terminal A is selected, if keyword 3 is the call code, terminal C is selected, and the power of each device is turned on.

〔Effect of the invention〕

As explained above, by adding a remote power-on function to a line adapter, the present invention allows terminals to be specified using a keyword code string, and terminals in remote locations can be powered on arbitrarily from a host device. effective.
