Description

  The present invention relates to a power supply control apparatus that controls a power supply facility that supplies power to a controlled facility from a remote location to reduce power consumption of the power supply facility.

  Since the controlled communication control device of the conventional network power control method does not have a function of suppressing its own power consumption, it consumes wasted power even when the communication control device is not used. In order to avoid this, for example, in the telemetry system disclosed in Patent Document 1, the power of the measurement device installed away from the station device is turned on only for a required time according to a request from the station device, and the battery is consumed. I try to suppress it.

Is inserted between. One relay contact 35A of the optical receiving relay coil 35 is inserted between the optical transmitter 23 and the power supply line 15, and the other relay contact 35B is connected in parallel to the contact 26A. A timer relay 29 that is driven by a pulse signal from the self-transmitter 14 for a certain period of time is provided between the self-transmitter 14 and the power line 15. The contact points 29A and 29B of the timer relay are the relay contact 35A and the relay contact 26B. Are connected in parallel.

  The self-transmitter 14 is a facility such as a rain gauge and emits a pulse signal when an event (for example, a certain amount of rainfall has been reached) is detected.

  The optical transmitters 6 and 21 of the control-side power controller 1 are connected to the optical receivers 8 and 24 of the controlled-side power controller 2 via optical cables 3 and 25, respectively. The optical receivers 7 and 20 of the control-side power controller 1 are connected to the optical transmitters 9 and 23 of the controlled-side power controller 2 by optical cables 19 and 22, respectively. In the above description, the optical transmission / reception unit is used as the transmission / reception unit, and the transmission line is an optical cable. However, the transmission line is not limited to one using light.

  Next, the operation will be described. In the control-side power controller 1, the optical transmitter 6 transmits an optical signal to the optical cable 3 by receiving a power-on signal from the computer 4 through the signal line 10. The controlled power supply controller 2 receives an optical signal through the optical cable 3 at the optical receiver 8. The light receiving unit 8 drives the light receiving relay coil 26 to close the contacts 26A and 26B. The light receiving relay coil 26 connects the controlled facility 5 to the power source facility 13 by closing the contact 26A of the light receiving relay. At the same time, the optical transmitter 9 is powered on at the contact 26B of the other optical reception relay. The optical transmitter 9 transmits an optical signal to the control-side power controller 1 through the optical cable 19 when the power is turned on.

  The control-side power supply controller 1 receives an optical signal from the controlled-side optical transmitter 9 at the optical receiver 7. The light receiving unit 7 passes a power-on confirmation signal through the signal line 11 to inform the computer 4 that the power to the controlled facility 5 has been turned on. The computer 4 can confirm that the power to the controlled facility 5 is turned on by a power-on confirmation signal from the control-side power controller 2.

  The other optical transmitter 21 of the control-side power controller 1 transmits an optical signal to the optical cable 25 by receiving a power-on signal from the computer 4 through the signal line 10. The controlled-side power supply controller 2 receives the optical signal through the optical cable 25 at the other optical receiver 24 and drives the optical reception relay coil 35 in the same manner as described above. The light receiving relay coil 35 turns on the power of the controlled equipment 5 at the contact 35B of the light receiving relay, and turns on the power at the light transmitting unit 23 at the contact 35A of the other light receiving relay. When the power is turned on, the optical transmitter 23 transmits an optical signal to the control side through the optical cable 22.

  After the control-side power supply controller 1 receives the optical signal from the controlled-side optical transmission unit 23 at the optical reception unit 20, the optical reception unit 20 supplies the computer 4 with power to the controlled facility 5. The input confirmation signal is passed through the same signal line 11 as described above. The computer 4 can confirm that the controlled-side power is turned on by a power-on confirmation signal from the control-side power controller 1.

  Next, the operation of the self-transmitter 14 will be described. The self-transmitter 14 is for urging power control from the controlled side to the control side when the control side pauses power control, that is, in a standby state. The self-transmitter 14 is a transmitter including, for example, a rain gauge. When the self-transmitter 14 measures a rainfall amount equal to or greater than a predetermined value, power is supplied to the controlled facility 5 to start operation of the controlled facility 5. Use in such cases.

  The self-transmitter 14 outputs a pulse signal through the signal line 18 by detecting that an event, for example, a certain amount of rainfall has been reached, and drives the timer relay 29. The timer relay 29 closes the contact points 29A and 29B of the timer relay for a predetermined time, and turns on the power of the optical transmitters 9 and 23. The optical transmitters 9 and 23 operate when the power is turned on, and transmit optical signals through the optical cables 19 and 22 toward the control side.

  The control-side power controller 1 receives the optical signal from the controlled side at the optical receivers 7 and 20, and receives the same signal as the power-on confirmation signal when the power of the controlled facility 5 is turned on with respect to the computer 4 on the signal line 11. Pass in. The computer 4 receives the same signal as the power-on confirmation signal from the control-side power controller 1. When the computer 4 receives the same signal as the power-on confirmation signal when the control side is in the standby state, the computer 4 determines that this signal is a power-on command request signal and sends a command to the optical transmitters 6 and 21 through the signal line 10. Then, the controlled power supply controller 2 is made to turn on the power of the controlled equipment 5.

  In the first embodiment, the power supply line 15 of the power supply facility 13 includes the light receiving units 8 and 24, the light receiving relay coils 26 and 35, the timer relay coil 29, the contacts 26A and 26B of the light receiving relay 26, and the light receiving relay. 35 contacts 35A and 35B and timer relay 29 contacts 29A and 29B. When the computer 4 is not performing power-on control, the optical reception relay coils 26 and 35 and the timer relay coil 29 are not driven, and thus no power is consumed. Further, since the contacts 26A, 26B, 35A, and 35B of the optical reception relay and the contacts 29A and 29B of the timer relay 29 are open, the optical transmission units 9 and 23 and the controlled equipment 5 do not consume power. Accordingly, since the optical receivers 8 and 24 are configured to consume power in a standby state in which power supply control is not performed, an apparatus with low power consumption during standby can be obtained. At this time, since the control side receives the power-on confirmation signal, when the power-on confirmation signal cannot be received even though the power-on instruction is given, it can be determined that the device or the transmission line is faulty.

  The computer 4 can recognize that the self-transmitter 14 has detected an event by receiving the same signal as the power-on confirmation signal when the power-on control is not performed. Since the power-on control on the controlled side is performed by detecting the event, a device that can voluntarily request the power-on control from the controlled side can be obtained.

  Further, the power-on signal from the computer 4 is simultaneously passed to the control-side optical transmitters 6 and 21, and the optical transmitters 6 and 21 transmit light to the optical cables 3 and 25 connected thereto, respectively. Light is received by the optical receivers 8 and 24 of the power supply controller 2. Since the optical receiving relay coil 26 operates by receiving light at either of the optical receiving units 8 and 24, a highly reliable device that does not hinder power supply control even if one of the optical cables 3 and 25 is disconnected. Obtainable.

  Further, the optical transmitters 9 and 23 on the controlled side simultaneously transmit optical signals to the control-side power supply controller 1 by closing the contacts 26B and 35A of the optical receiving relay or the contacts 29A and 29B of the timer relay 29. If an optical signal is received by either of the optical receivers 7 and 20 of the control-side power controller 1, the signal can be passed to the computer 4 via the signal line 11, so that even if either of the optical cables 19 and 22 is disconnected, the signal is transmitted. Therefore, a highly reliable device can be obtained.
