Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote power control device, and particularly to a remote power control device that starts or stops power supply by remote control from a remote location.

[Summary of the Disclosure] This specification and drawings particularly describe a receiving means for receiving a remote power control signal and a receiver of the receiving means in a remote power supply control device that starts or stops power supply by remote control from a remote location. a control means for controlling the power on of the power supplied device based on a control signal, a detection means for detecting a predetermined state of the power supplied device, and a means for changing the power on control based on the signal detected by the detection means. The present invention discloses a technique for a remote power control device that performs appropriate power-on control according to a predetermined state of a power-supplied device.

[Prior Art] Conventionally, this type of device receives a signal from the outside (for example, an incoming telephone call, etc.). It has the function of supplying power to the device and starting a series of processes. However, if the connected device is a highly sensitive electronic device such as a personal computer, its operation is highly dependent on the installation environment of the device 2, so it may not be possible to expect normal operation just by starting power supply. When powering on electronic equipment in cold regions, it is especially necessary to allow sufficient time for warming up. However, conventional remote power on/off devices do not take such situations into consideration, and as a result, electronic devices are operated in an unstable state, resulting in inconvenience.

[Problems to be Solved by the Invention] The present invention seeks to provide a remote power supply control device that automatically solves the above-mentioned problems associated with the installation environment of a power-supplied device at a remote location.

Measures for Solving Problem c] As a means for solving this problem, for example, the remote power on/off device of the embodiment shown in FIG. ! 2 is the transmission line 30
0, and based on the power on/off signal RC output from the receiving means 11, line lO1 and line 102
A control means (decoder) 12 that performs power on/off control of the power-supplied device ll via the power-supplied device ! detection means 9 for detecting whether the temperature state of l is sufficient for Mm operation; and means for guiding the output signal TS of the detection means 9 to a power on/off device to change the power on/off control in the decoder 12. Equipped with.

[Function] In the configuration shown in FIG. 1, when there is a remote power-on request from the transmission line 300, the detection signal RC goes to logic level l.
become. However, if the device is cold, operation cannot be guaranteed immediately, so in this state, the remote power-on request is changed because the logic level of the temperature detection signal TS is 0, and the output of the decoder 12 is That is, the solid state relay (ssR) 5 of the powered device 1
is turned on and the device I enters the preheating state. Further time passes in this state, and when the temperature detection means 9 detects that the predetermined temperature has been exceeded, the signal TS becomes 1, and the output of the decoder 12 becomes l.
3. There is no risk of malfunction even if IT, that is, device 1, is operated, so instead of cutting off 5SR5, 5SR4 is made conductive to bring the device into operation.

[Examples] Examples of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block configuration diagram of a remote power on/off device and a power supplied device according to an embodiment. In FIG. 0 connected by the temperature detection signal line 201 of the power-supplied device 1 shows the connection for one power-supplied device, but the power supply on/off control lines may be 101 to 1Qn. possible, and the equipment status detection line is also 201.
~20m is possible.

In the power supplied device 1, 3 is a DC power supply for power control that is constantly supplied to receive remote control, and 4 and 5 are AC power supplies.
Solid state relay (SS) for power line on/off
R), 6 is the main DC power supply of the device l, 7 is a device preheating device for cold region specifications, 8 is an electronic control circuit section consisting of semiconductor elements, 9
is a temperature detection means arranged at a predetermined position of the device (for example, near the electronic control circuit section 8).

In addition, in the remote power on/off device 2, 10 is a device! 2 is a DC power source; 11 is a receiving means for receiving a remote power on/off request signal sent via a transmission line (telephone line, etc.) 300; 12 is a remote power on/off control signal RC on line 401 and a temperature detection signal on line 201; A decoder 13 determines the control level of the power on/off control lines 101 and 102 from the temperature detection means, and receives the LO level signal from the temperature detection means indicating that the temperature is below a predetermined value, and sends the signal to the caller via the transmission line 301. This is a means of transmitting information.

In such a configuration, solid state relays (SSRs)
) 4 and 5 (+) terminals are DC power supply 3 for regular power supply control.
Output voltage Vn is applied and 5SR(7)(-)
If ground level is applied to the terminal, AC input terminal AB
AClooV is applied to AC output terminal ab. On the other hand, the temperature detection means 9 outputs an LO rerel signal (0) to the line 201 when the detected temperature is below a predetermined value, and outputs a HI level signal (1) when it is higher than the predetermined value, and outputs a HI level signal (1) to the input 2 of the decoder 12. 'S bit is determined. When the receiving means 11 receives the remote power-on request signal via the transmission line 300, the receiving means 11 uses the signal to turn on the flip-flop means (not shown).
When the remote power off signal is received, the flip-flop means is reset and the LO level signal (0) is continued to be output to the line 401, and the decoder 12 input l'
Determine the S bit.

FIG. 2 is a state diagram illustrating the operation of FIG. 1. In the figure, when both the signal TS and the signal RC are O, there is no remote power-on request and the device 11 is in a cold state. The decode output of the decoder 12 is 0", and nothing is done. Next, if a remote power-on request is made in this state, the signal RC becomes 1. However, since the device is cold, normal operation is immediately guaranteed. It is not possible, therefore,
In this state, the remote power-on request is changed because the signal TS is 0, and the decoded output of the decoder 12 is "1", that is, 5SR5 is conductive and the preheating state is entered. Further, the transmitter 13 notifies the caller that the preheating state is present. Further, after a period of time has elapsed in this state, when the temperature detecting means 9 detects that the predetermined temperature has been exceeded, the signal TS becomes 1, and the output of the decoder 12 automatically changes to "3". 1
2111 Since we are now in a state where there is no risk of malfunction even if device l is operated, instead of shutting off 5SR5,
conducts and puts the device into operation. In this way, the host side (not shown) connected to the transmission line 300 can ensure normal operation of the remote device by simply issuing a power-on request, without having to take into account the conditions of the remote device. This is the translation. From then on, the device 1 maintains the operating temperature with its own blade.When the host issues a remote power off request, the decode output of the decoder 12 becomes ``2P'' and the power of the device 1 is turned off. Since it takes a considerable amount of time for the detection means 9 to detect a temperature below the predetermined temperature, if a remote power-on request is received again before then, the device will be turned on immediately.
The power is turned on and the machine is ready for operation. Further, if the temperature detecting means 9 detects a temperature below a predetermined temperature, the state returns to the first state.

Incidentally, as described above, the embodiment device 2 has a plurality of power-supplied devices l.
It can be configured to control 6 units! ! 11, each device 1 can be controlled independently by changing the signal sent to the transmission line 300, for example. Furthermore, it is clear that the device 12 may be configured integrally with the device 1.

[Effects of the Invention] As described above, according to the present invention, preheating is automatically performed when power is supplied to a remote personal computer, etc., especially in a cold region, so it is not necessary to turn on the power in a non-operating environment. This can prevent malfunctions and damage to the equipment.
