The opening / closing unit 22 includes a relay having a normally closed contact. For example, while the control signal is at the H level, the relay winding is excited to open the contact, and while the control signal is at the L level, the relay winding is excited. Instead, the contacts are closed, and operating power for exciting the relay winding is supplied from the power supply circuit section 14 of the main body controller 10 via the communication cable 3.

The communication cable 3 is, for example, 10BASE-

A modular jack MJ to which MP is connected is arranged, and a power cord 5 to be connected to a commercial power source AC is led out from one end face in the longitudinal direction. The structure for preventing the insertion port 21a from coming off is well known in the art, and therefore the description thereof is omitted.

As shown in FIG. 4, a printed wiring board 23 having an outlet 21 and an opening / closing portion 22 mounted therein is housed inside the housing 4. The printed circuit board 23 is a multilayer printed wiring board as shown in FIG. 5, the feedline inner layer 23a ₂ from the commercial power source AC to the respective outlet portions 21
Formed in ~23a _5, the signal path of the control signal is one of the outer layers 23a _1, frame ground are formed on the other of the outer layer 23a _6. Here, two adjacent inner layers 2
Since 3a ₂ and 23a ₃ are the voltage poles of the commercial power supply AC and the remaining two adjacent inner layers 23a ₄ and 23a ₅ are neutral poles, the inner layers 23a ₂ and 23a ₃ and 23a ₄ and 23a _{5 of the} same polarity are used.
Can be the thickness of the insulating layer 23b _2, 23b ₄ interposed interlayer smaller than the other insulating layer 23b _1, 23b _3, the thickness of 23b _5. The other insulating layers 23b ₁ and 2
It is necessary that 3b ₃ and 23b ₅ have a thickness that ensures a sufficient insulation distance. In addition, the conductor layer (inner layer 23a ₂ ~
The thickness of the copper foil of 23a ₅ and the outer layers 23a ₁ and 23a ₆ ) is set to a dimension (for example, about 70 μm) that can obtain a sufficient current capacity, but if the width of the copper foil can be set to a sufficiently large value, it should be half of that. The thickness may be about 35 μm.
However, the relative positional relationship between the voltage pole and the neutral pole of the power feeding path and the signal path of the control signal and the frame ground may be exchanged.

By thus forming the power feeding path from the commercial power source AC to the outlet portion 21 with the printed wiring board 23, the assembling work is simple as compared with the case where the power feeding path is formed by using an electric wire such as an IV wire. Can be realized. In addition, there is an advantage that it is possible to reduce the points of processing management such as the presence or absence of scratches on the electric wire at the time of assembly and the insulation distance.

In the power supply control device 1 configured as described above, as shown in FIG. 3, the main body controller 10 is fixed to the mount frame 103 together with the information equipment 110, and the power supply control unit 20 is a dead space of the rack 100.

Further, it is also possible to control the operation of the information equipment 110 by a timer by using the timer built in the microcomputer to generate a control signal in the control unit 11 according to a preset schedule. In this embodiment, since the normally-closed contact relay is used for the opening / closing unit 22, even if the control signal cannot be received due to some failure in the main body controller 10 or the communication cable 3, the power control is performed. Unit 20 to information device 11
The power supply to 0 can be continued. Moreover, the information device 110
Since it is not necessary to apply an exciting current to the relay when the power is supplied to the relay, it is possible to suppress heat generation in the opening / closing unit 22 when the information device 110 is powered, as compared with the case where a relay having a normally open contact is used.

Thus, in the present embodiment, the power supply control device 1 is divided into the main body controller 10 and the power supply control unit 20, and the two are connected by the communication cable 3. This can be dealt with by increasing the number of power supply control units 20, and moreover, the size of the power supply control unit 20 can be easily reduced as compared with the conventional structure in which the main body controller 10 is integrated. Therefore, the rack 10
It is possible to install the power supply control unit 20 in a dead space in which the information device 110 is not housed, and as a result, it is possible to suppress the occupation ratio of the housing space in the rack 100. In this embodiment, the number of the opening / closing sections 22 and the outlet sections 21 is 6, but since the modular plug MP and the modular jack MJ of RJ-45 have 8 cores, control signals can be sent to a maximum of 7 opening / closing sections 22. Can be sent.

By the way, as shown in FIG. 6, it is desirable to provide a fuse 24 for interrupting an overcurrent in the power supply path from the commercial power supply AC to the outlet portion 21 in the power supply control unit 20. That is, when an overcurrent flows into each information device 110 connected to the outlet section 21 or the total input current flowing from the commercial power supply AC exceeds the rating, the fuse 24 is blown to open the power supply path. It is possible to prevent the overcurrent from flowing to the information device 110 and the power supply control unit 20 and improve the safety.

(Embodiment 2) The power supply control device 1 of the present embodiment is characterized in that the power supply control unit 20 is provided with a power supply outlet 25 that is fed by a commercial power supply AC. Since the third embodiment is common to the first embodiment, common constituent elements are given the same reference numerals, and illustration and description thereof are omitted.

The sending outlet section 25 has an insertion opening 25a having a retaining structure so that the commercial power source A can be operated without going through the opening / closing section 22.
It is connected to the power feeding path from C, and as shown in FIG. 7, the insertion port 25a of the outlet socket 25 for feeding is exposed at the other longitudinal end surface of the housing 4 of the power supply control unit 20. A power plug 5a with a ground electrode is attached to the tip of the power cord 5 led out from the housing 4.

Thus, the first power supply control unit 20 ₁
It is directly connected to a commercial power supply AC to plug the power cord 5a into a wall outlet (not shown) or the like, for the second power control unit 20 _2, first unit of the power supply control as shown in FIG. 8 Outlet part 25 for sending unit 20 ₁
By inserting the power plug 5a into the insertion port 25a, the commercial power AC is connected via the _first power control unit 20 ₁ . Similarly, for the third power supply control unit 20 ₃ , the power supply plug 5a is inserted into the insertion port 25a of the feed outlet 25 of the _second power supply control unit 20 _2.
Is connected to the commercial power supply AC via the first and second power supply control units 20 ₁ and 20 ₂ .

Thus, in this embodiment, the power cord 5
Power supply control unit 2 connected to commercial power supply AC via
The power source control unit 20 can be easily added by simply connecting the power source plug unit 5a of the other power source control unit 20 _{2 to} the 0 ₁ feeding outlet section 25, and the construction work can be simplified. That is, although a qualification is required for power supply work such as the addition of a wall outlet, even if the contractor (system integrator) who introduces the information device 110 does not have the above qualification, the power control unit 20 can be added. it can.

(Embodiment 3) The power supply control device 1 of the present embodiment is provided with a network connection means for connecting to the network in the main body controller 10, and receives on / off information from the management terminal 200 on the network via the network. The configuration and operation other than this are common to those of the first embodiment, and thus common components are denoted by the same reference numerals, and illustration and description thereof are omitted.

As shown in FIG. 9, the main body controller 10 of the present embodiment is a network connecting means L for connecting to an Ethernet (R) which is a current standard LAN.
An AN controller 15 is provided. The LAN controller 15 is connected to an LA via an RJ-45 modular connector (modular plug and modular jack) (not shown).
It is connected to the N cable 6 and controls communication between the control unit 11 and devices on the LAN (the management terminal 200 and other terminals, the server 201, etc.). However, since such a LAN controller 15 is well known in the art, illustration and description of the detailed configuration will be omitted.

The rewritable non-volatile memory (EEPROM etc.) 13a included in the memory section 13 is
A driver for the control unit 11 to control the LAN controller 15 and a TCP (Transmissinon Control Protocol)
l), IP (Internet Protocol), UDP (User Datag)
ram Protocol), ICMP (Internet Control Messag)
e Protocol), SMTP (Simple Mail Transfer Proto)
col), Telnet, HTTP (Hypertext Transfer Proto)
col), SNMP (Simple Network ManegementProtoco
A protocol stack in TCP / IP communication such as l) and a program for controlling the power supply control unit 20 as described above are stored. It is loaded into the memory 13b and executed.

On the other hand, the management terminal 200 is composed of a general-purpose computer device such as a personal computer, and has an operating system (WINDOWS (R) or UNIX (R) of Microsoft Corp.) in which a protocol stack similar to that of the control unit 11 of the main body controller 10 is mounted. )Such)
W that runs on the operating system
By executing a program for the EB browser or the SNMP manager, it is possible to output the on / off information to the main body controller 10 to remotely control the power supply control unit 20 or monitor the control state of the power supply control device 1. That is, a unique network address (IP address) is assigned to the main body controller 10 and the management terminal 200 on the LAN or WAN network.
When the IP address of the main body controller 10 on the network is accessed from the WEB browser of the management terminal 200, the control unit 11 of the main body controller 10 executes the control and monitoring program stored in the non-volatile memory 13a to perform the control and monitoring. Data in HTML format for use in transmission to the management terminal 200 via the network. This HT
The ML format data is provided for providing an interface for controlling and monitoring the power supply control device 1 by the management terminal 200, and the power supply is provided on the monitor of the management terminal 200 based on the transmitted HTML format data. The control status and the like in the control device 1 is displayed on the WEB browser, and ON / OFF information for controlling the ON / OFF of the power supply to any information device 110 by operating the keyboard or mouse is also transmitted via the WEB browser. Controller 1
Can be sent to 0.

Further, the controller 11 of the main body controller 10
By executing the program for the SNMP agent at the management terminal 200, which is the SNMP manager,
It is possible to easily acquire the management information of the main body controller 10 which is an NMP agent (such as the state of on / off control in the power supply control unit 20 and the time when the state of on / off control changes) via the network. The management function using SNMP is well known in the related art, and thus detailed description thereof will be omitted. Here, the control unit 11 of the main body controller 10 has a function of periodically acquiring time data from the server 201 that manages accurate time via the network and correcting the current time of the internal clock, The accuracy of the time included in the management information is improved.

By the way, the information equipment 110 which is supplied with power from the power supply control device 1 is also connected to the network, and each information equipment 110 is assigned a unique network address (IP address). Then, in the non-volatile memory 13a of the main body controller 10, the network address assigned to the information device 110 to be controlled that is supplying power is registered in advance together with the type of the information device 110 (server, router, etc.). There is. The control unit 11 of the main body controller 10 uses the ICMP
The life and death status of the information device 110, that is, whether or not the information device 110 can normally communicate is monitored by a sequence called an echo. Specifically, the control unit 11 periodically
Executing the ping command, sending a message to the registered network address via the LAN controller 15, and measuring the time until a response is returned from the information device 110 of the transmission partner, thereby determining the life and death status of the information device 110. Is judging.

Here, when it is determined that any one of the information devices 110 is in a communication-disabled state, the control unit 11 takes the following measures according to the type of the information device 110. For example, when the target information device 110 is a network device such as a router, there is a possibility of recovery by a so-called power reset, so a control signal is output to the opening / closing unit 22 to supply power to the information device 110. Turn off the power supply and then turn it on again.

On the other hand, when the target information device 110 is a server, the power cannot be easily turned off, so only the abnormality of the server is reported to the network administrator. At this time, electronic mail is used as a method of notifying the network administrator of the details of the abnormality. That is, the e-mail address (there may be a plurality) of the other party for notifying the abnormality content as described above is registered in the non-volatile memory 13a in advance, and when the abnormality occurs in the control unit 11, the normal mail Non-volatile memory 13a using SMTP like e-mail
The electronic mail in which the type of the information device 110 in which the abnormality has occurred, the network address thereof, and the details of the abnormality are described is transmitted to the destination mail address registered in. The control unit 1 which is an SNMP agent
By executing the trap, which is the basic command of SNMP, at 1, the management terminal 20 that is the SNMP manager
It is also possible to notify 0 of the above-mentioned abnormality content, and by transmitting on / off information from the management terminal 200 in accordance with the abnormality content, the on / off control of the power supply control unit 20 can be performed via the main body controller 10. is there.

Thus, the network device (information device 110) such as a switching hub or router has complicated internal processing, and the higher the function is, the more problems may occur in the mutual connection and the deadlock may occur. In the present embodiment, since the main body controller 10 constantly monitors the life and death status of the information device 110, the occurrence of such a deadlock can be found promptly, and in some cases, automatic recovery by power reset is also possible. . As a result, the network administrator can remotely perform maintenance of the information device 110 without going to the site, and the management cost can be reduced.

(Embodiment 4) FIG. 10 shows a block diagram of the main body controller 10 in the present embodiment. However, since the basic configuration of the power supply control device 1 including the main body controller 10 is the same as that of the third embodiment, common components are denoted by the same reference numerals, and illustration and description thereof will be omitted. Only the points will be described.

The present embodiment is characterized in that the power supply circuit section 14 is separated into a first power supply circuit section 14a and a second power supply circuit section 14b, and that a reset circuit section 16 is provided in the main body controller 10. is there.

Although not shown, the first power supply circuit section 14
The circuit configuration of the second power supply circuit section 14a and the circuit configuration of the second power supply circuit section 14b are almost the same.
6 operating power supply (DC power supply of power supply voltage Va = 5V) is generated, and the operating power supply of the control signal transmitting unit 12 and the opening / closing unit 22 of the power supply control block 20 (power supply voltage Vb = 12V of the second power supply circuit unit 14b). DC power supply) is different.

By supplying two types of operating power supplies having different power supply voltages by independent circuits (first and second power supply circuit sections 14a and 14b) respectively, an external force induced by the communication cable 3 is generated. The influence of noise is less likely to reach the first power supply circuit unit 14a, and malfunction of the control unit 11 and the like due to the noise can be prevented. It is also possible to make the power supply voltage Vb of the operating power supply created by the second power supply circuit section 14b higher than the power supply voltage Va of the other operating power supply to increase the noise margin for external noise. Furthermore, when a plurality of opening / closing sections 22 are collectively turned on / off, a large current instantaneously flows and the power supply voltage Vb temporarily decreases. However, such a decrease in the power supply voltage Vb has an effect. Since it does not reach the control unit 11 and the like of the main body controller 10, there is an advantage that the operation of the main body controller 10 is stable.

On the other hand, the reset circuit section 16 monitors the power supply voltage Va supplied from the first power supply circuit section 14a, and forcibly controls the control section 11 when the power supply voltage Va falls below the guaranteed operation range of the control section 11. The control signal transmission unit 12 stops the control signal transmission from the control signal transmission unit 12 to the power supply control block 20 when the control unit 11 is reset. In the control unit 11, even when the internal reset of the CPU is performed by the watchdog timer included in the microcomputer, the reset circuit unit 16 causes the control signal transmission unit 12 to transmit the control signal to the power control block 20. It is supposed to stop.

On the other hand, the opening / closing section 22 of the power supply control block 20.
Since the relay has a normally-closed contact, the relay does not operate and the contact is closed when a control signal is not input, thus forming a power supply path to the outlet 21.
Therefore, the power supply to the information device 110 can be continued even when the control unit 11 of the main body controller 10 is reset.

(Embodiment 5) This embodiment is characterized in that a power supply control system is configured by adding a power monitoring unit 30 to the power supply control device 1 as shown in FIG. However,
Since the basic configuration of the power supply control device 1 is the same as that of the first and fourth embodiments, common constituent elements will be denoted by the same reference numerals and description thereof will be omitted.

The power monitoring unit 30 measures the power supplied from the commercial power supply AC to the information equipment 110 via the power supply control unit 20 of the power supply control device 1 and the power measuring unit 31.
And an arithmetic processing unit 32 that generates electric power monitoring information based on the measurement result of the electric power measuring unit 31, and the electric power monitoring information generated by the arithmetic processing unit 32 to the main body controller 10 via the communication cable 7 and the main body. A data transceiver 33 for receiving data from the controller 10,
The memory unit 34 stores a program for arithmetic processing executed by the arithmetic processing unit 32, calibration data to be described later, and the like.

The power measuring unit 31 measures the input current from the commercial power source AC to the power source control unit 20 using a current transformer and measures the input voltage from the commercial power source AC to the power source control unit 20 using a voltage dividing resistor. The voltage / current measuring unit 31a and the analog detection values output from the voltage / current measuring unit 31a are fetched, the detected values are calibrated by referring to the calibration data stored in the memory unit 34, and then the detected values are calibrated. AFE (analog / analog conversion) that A / D converts and obtains the measured value of power (supply power) from digital detection value
Front end) circuit section 31b. AFE
The circuit unit 31b is a conventionally well-known device including an LSI in which an A / D conversion circuit and a serial port interface are integrated on one chip, and the measured value data of current / voltage and power is serially communicated to the arithmetic processing unit 32. Send.

The arithmetic processing unit 32 is composed of a microcomputer having a CPU as a main component, and has a serial port interface for serial communication with the power measuring unit 31,
It is equipped with a serial interface or the like for performing serial communication with the main body controller 10 via the data transmission / reception unit 33, and based on the measured value data of the power received from the power measurement unit 31, the power monitoring information (current / current The measured value data of voltage and electric power and information such as whether these measured values are normal values or the like are generated.

The data transmission / reception section 33 uses a photocoupler or the like to insulate the communication cable 7 from the arithmetic processing section 32, and relays data communication (serial communication) between the arithmetic processing section 32 and the main body controller 10. There is. Here, a twisted pair cable for LAN is used as the communication cable 7, and the data transmitting / receiving unit 33 is provided with a modular jack (not shown) into which the modular plug (RJ-45) of the communication cable 7 is inserted and connected. ing. However, communication cable 7
It is also possible to use a modular cable for telephones. When using a photo coupler for insulation,
The operation power supply Vb of the photocoupler may be supplied from the second power supply circuit unit 14b included in the main body controller 10 via the communication cable 7.

The memory section 34 comprises a non-volatile memory,
Programs and calibration data executed by the CPU of the arithmetic processing unit 32 are stored. The calibration data is composed of offset calibration for A / D conversion, gain calibration, and data such as a conversion coefficient from voltage / current to power, and is stored in the memory unit 34 when the power monitoring unit 30 is manufactured and shipped.

As shown in FIG. 12, the power monitoring unit 3
0 has a box-shaped housing 35, and the housing 3
A power cord 36 having a power plug 36a connected to a commercial power source AC attached thereto is led out from one end face in the longitudinal direction of 5, and the power control unit 20 or the power plug 5a of the information device 110 is inserted into the other end face. An outlet 37a of an outlet 37 for connection is exposed, and a modular jack MJ to which a modular plug of the communication cable 7 is connected is provided on the front surface of the housing 35. The outlet part 37 is connected to the commercial power supply AC in the housing 35 as shown in FIG.
As shown in (a), the power plug 36a is inserted into a wall outlet (not shown) or the like to connect to the commercial power AC, or as shown in (b) in FIG. The plug-in connection allows commercial power AC to be supplied to the device connected to the outlet 37.
Power is supplied from.

On the other hand, the main body controller 10 is provided with a modular jack (not shown) into which a modular plug of the communication cable 7 is inserted and connected, and a transmission / reception section for performing serial communication with the power monitoring unit 30 via the communication cable 7. 17
Is provided. Here, although only one transmission / reception unit 17 is shown in FIG. 11, a plurality of transmission / reception units 17 are provided in the main body controller 10 and a plurality of power monitoring units 30 are connected to one main body controller 10. It is possible to monitor the electric power of the information devices 110 connected to different power supply control units 20 via the monitoring unit 30.

By the way, when a plurality of power monitoring units 30 are connected to the main body controller 10, it is necessary for the control unit 11 of the main body controller 10 to identify each power monitoring unit 30, and therefore each power monitoring unit 3 is required.
An identification symbol (ID number) unique to 0 is assigned by the control unit 11. For example, the power monitoring unit 30 is pre-assigned with an ID number of “0” as a default value, and the control unit 11 of the main body controller 10 sets the power monitoring unit connected to each transmission / reception unit 17 as an initial setting during construction. The ID number is inquired to 30.
Here, the main body controller 10 and the power monitoring unit 30
13, the packet in which the ID number is added to the head of the command and the data is transmitted and received as shown in FIG. Thus, the control unit 11 transmits a packet including a command for inquiring about the ID number of the other power monitoring unit 30 to the power monitoring unit 30 connected to each transmission / reception unit 17 without specifying the ID number. If the ID number returned from the power monitoring unit 30 is the default value "0", a packet for assigning the ID number is transmitted to the power monitoring unit 30 having the ID number "0", and the default value is transmitted. ID numbers other than (for example, 1
(Integer values up to 255) are sequentially assigned. For the power monitoring unit 30 having an ID number other than the default value, the ID number has already been changed to another power monitoring unit 3.
If it overlaps with the ID number assigned to 0, it is once set to the default value, and then a new ID number is assigned by the above procedure. If the ID number is not assigned to another power monitoring unit 30, it is used as it is. By such processing, the control unit 11 of the main body controller 10 can allocate and identify individual ID numbers to the individual power monitoring units 30 connected to the plurality of transmission / reception units 17.

Thus, the control unit 1 of the main body controller 10
1 can acquire the power monitoring information from each power monitoring unit 30 by periodically transmitting a command for returning the power monitoring information to each ID number. Then, if it is determined that the voltage value or current value detected by any of the power monitoring units 30 exceeds the rated value of the information device 110 based on the power monitoring information, From the control unit 11 to the power supply control unit 2
It is possible to prevent the information device 110 from being damaged due to overvoltage or overcurrent by transmitting a control signal to 0 to cut off the power supply path to the information device 110 in which the abnormality has occurred.

As described above, in the power supply control system of this embodiment, the power supply status to the information equipment 110 can be collectively monitored by the main body controller 10. Further, since the power monitoring unit 30 is connected to the power supply control device 1 separately from the communication cable 7, it is possible to cope with an increase in the number of information devices 110 by increasing the power monitoring unit 30. Since the power monitoring unit 30 can be easily downsized as compared with the case where the power monitoring unit 30 is integrally configured, the power monitoring unit 30 can be installed in the dead space in the rack 100 like the power supply control unit 20.

By the way, in the present embodiment, a backup of the calibration data is stored in the main body controller 10 in case the calibration data stored in the memory section 34 of the power monitoring unit 30 is damaged or lost due to some trouble. I am trying. That is, at the time of the above-described initialization, the control unit 11 downloads the calibration data stored in the memory unit 34 by transmitting a command to the power monitoring unit 30 to which an individual ID number is assigned, and the main body controller 10 It is stored in the memory unit 13 in association with the ID number. And
When the calibration data is damaged or lost in any of the power monitoring units 30, the memory unit 13 of the main body controller 10
From the multiple calibration data backed up in
The calibration data of the power monitoring unit 30 can be specified based on the D number, uploaded from the transmission / reception unit 17, and the original calibration data can be written back to the memory unit 34.

Thus, even when some abnormality occurs and the calibration data stored in the memory section 34 of the power monitoring unit 30 is damaged or lost, the main body controller 10
The calibration data backed up can be written back to the memory unit 34 of the power monitoring unit 30, and can be easily restored without the trouble of performing calibration again.

(Embodiment 6) This embodiment is the same as Embodiment 3.
Similarly to the above, the main body controller 10 is provided with a network connection means for connecting to the network. However, since the basic configuration of the main body controller 10 is the same as that of the third embodiment and the configurations of the power supply control unit 20 and the power monitoring unit 30 are the same as those of the first and fifth embodiments, respectively, illustration and description thereof will be omitted.

Main body controller 10 in the present embodiment
14 includes a LAN controller 15 as shown in FIG. 14, and has a configuration in which the transmission / reception unit 17 in the fifth embodiment is added to the main body controller 10 in the third embodiment.

By using the WEB browser of the management terminal 200, the power monitoring information acquired by the control unit 11 of the main body controller 10 from the power monitoring unit 30 can be browsed via the network. Therefore, when it is determined based on the power monitoring information that an abnormality such that the voltage value or the current value detected by any of the power monitoring units 30 exceeds the rated value of the information device 110 occurs, On / off information is transmitted from the management terminal 200 to the main body controller 10, and a control signal is transmitted from the control unit 11 of the main body controller 10 to cut off the power supply path to the information device 110 in which the above-mentioned abnormality has occurred, thereby overvoltage or overvoltage. Information device 1 by electric current
It is possible to prevent breakage of 10 and the like. Further, when the current value exceeds the threshold value set to a value slightly lower than the rated value, the power supply to the new information device 110 is prohibited, or the power supply to the information device 110 having a lower priority is cut off. May be. In addition, in the control unit 11 of the main body controller 10, S
If you execute the program for NMP agent, SN
The power monitoring information acquired by the control unit 11 of the main body controller 10, which is an SNMP agent, can be easily acquired by the management terminal 200, which is an MP manager, via a network.

When it is determined from the power monitoring information that an abnormality has occurred, the controller 11 of the main body controller 10
The network administrator is notified by sending an e-mail in which the time when the abnormality occurred in the mail address registered in advance in the non-volatile memory 13a and the details of the abnormality are transmitted.
The control unit 11 which is an SNMP agent uses the SN
It is also possible to notify the management terminal 200, which is an SNMP manager, of the above-mentioned abnormality content by executing a trap that is a basic MP command.

By the way, the LAN controller 15 and LA
Main unit controller 10 due to trouble of N cable 6
Is unable to connect to the network, transmission of power monitoring information to the management terminal 200, notification by e-mail to the network administrator, etc. is disabled, or an abnormality is determined from the power monitoring information. In this case (in such a case, there is a possibility that the operation of the information device 110 in which an abnormality has occurred is stopped and the connection to the network is disabled), the control unit 11 of the main body controller 10
The periodically acquired power monitoring information is sequentially stored in the non-volatile memory 13a of the memory unit 13 in time series together with the acquired time. Thus, when the above-described abnormality occurs, the power monitoring information can be traced back in the past by the time-series power monitoring information stored in the non-volatile memory 13a, and the cause of the abnormality can be easily identified. Has the advantage that

(Embodiment 7) The present embodiment is characterized in that the power monitoring unit 30 is provided with reset means for resetting the arithmetic processing unit 32 in accordance with an instruction given from the control unit 11 of the main body controller 10. However, since the basic configuration of the power supply control device 1 including the main body controller 10 and the power monitoring unit 30 is the same as that of the sixth embodiment, common components are designated by the same reference numerals, and illustration and description thereof will be omitted.

As shown in FIG. 15, the main body controller 1

Reset signal is transmitted through separate signal lines of the communication cable 7, and the data transmission / reception unit 33 of the power monitoring unit 30 has the communication cable 7 and the arithmetic processing unit 32 as described in the fifth embodiment. Photocouplers PC1 to PC3 are provided to insulate each other.

In this embodiment, when the reset command is transmitted from the control unit 11 of the main body controller 10 to the power monitoring unit 30, the arithmetic processing unit 32 of the power monitoring unit 30 performs the reset operation according to the reset command. It is configured. Further, the power monitoring unit 30 in the present embodiment is provided with a reset unit 38 that receives a reset signal transmitted from the control unit 11 of the main body controller 10 and resets the arithmetic processing unit 32. That is, in the present embodiment, the arithmetic processing unit 32 that performs the reset operation according to the reset command and the reset unit 38 that resets the arithmetic processing unit 32 according to the reset signal correspond to the reset means.

The reset of the arithmetic processing unit 32 of the power monitoring unit 30 is performed by the control unit 11 of the main body controller 10.
Power monitoring unit 30
This makes it possible to simplify the recovery work when an abnormality occurs in the. Moreover, when the reset by the reset command is impossible, the reset signal can be transmitted to the reset unit 38 to forcefully reset the arithmetic processing unit 32.

(Embodiment 8) This embodiment is characterized in that a power supply control system is configured by adding a temperature monitoring unit 40 to the power supply control device 1 as shown in FIG. However,
Since the basic configuration of the power supply control device 1 is the same as that of the first and fourth embodiments, common constituent elements will be denoted by the same reference numerals and description thereof will be omitted.

The temperature monitoring unit 40 includes a temperature sensor 41 for generating an electric signal according to the detected temperature and a temperature sensor 4
A data transmission / reception unit 42 that transmits temperature measurement value data obtained by signal processing an electric signal generated from the main controller 1 to the main body controller 10 via the communication cable 8 and receives commands and the like transmitted from the main body controller 10. In the present embodiment, a serial output temperature sensor, which is a device for a measurement control bus system named “MicroLAN” developed by Dallas Semiconductor Inc., in which the temperature sensor 41 and the data transmitting / receiving unit 42 are integrated on one chip. Using IC (product number: DS1820),
An RJ-11 modular jack (not shown) for connecting C and the communication cable 8 is housed in a case to form a temperature monitoring unit 40. Here, a brief explanation of Dallas Semiconductor's "MicroLAN",
A device to which a unique ID code is assigned is connected to the measurement control device in a daisy chain by a multi-core (signal line, power supply line, and ground) type communication cable (for example, a telephone modular cable). Is a measurement control bus system that enables the measurement control device to identify individual devices and send and receive measurement value data, etc. to and from each device. There is an advantage that the wiring can be greatly simplified as compared with the installed measurement control system.

On the other hand, the main body controller 10 is equipped with an RJ-11 modular jack (not shown) into which the modular plug of the communication cable 8 is inserted and connected.
A transmission / reception unit 18 for serially communicating with the temperature monitoring unit 40 via the temperature monitoring unit 40 is provided. This transmission / reception unit 18 uses the “Micr
oLAN "bus control driver IC (Product number: DS248

It can be taken into the main body controller 10 via the communication cable 8 and can be collectively monitored. The control unit 11 of the main body controller 10 monitors the operation state of the information device 110 based on the temperature measurement value data sent from the temperature monitoring unit 40, and the temperature measurement value data indicates the operation guarantee range of the information device 110. When it is determined that an abnormality that causes the abnormality is occurring, an appropriate measure such as transmitting a control signal to the power supply control unit 20 to cut off the power supply path to the information device 110 in which the abnormality occurs It can be performed.

As described above, in the power supply control system of this embodiment, the main body controller 10 can collectively monitor the ambient temperature in the rack 100 and the temperature of the information equipment 110. In addition, the temperature monitoring unit 40 is connected to the power supply control device 1
Since the configuration is such that the communication cable 8 is connected separately from the above, it is possible to cope with an increase in the number of measurement locations due to an increase in the number of information devices 110 by increasing the temperature monitoring unit 40.
Since the temperature monitoring unit 40 can be easily downsized as compared with the case where it is integrally configured with the power supply control device 1, it can be installed in the dead space in the rack 100 as with the power supply control unit 20.

(Embodiment 9) In this embodiment, as shown in FIG. 17, another temperature monitoring unit 40 is formed by a daisy chain.
A normally open analog switch unit 43 for opening and closing a port connected to the main body controller 10 and the data transmitting / receiving unit 4
The temperature monitoring unit 40 is characterized in that the temperature monitoring unit 40 is provided with a control circuit unit 44 that controls the opening and closing of the analog switch unit 43 according to the communication status with the communication unit 2. However, since the other configurations are common to those of the eighth embodiment, common components are denoted by the same reference numerals, and illustration and description thereof are omitted.

As described in the eighth embodiment, the plurality of temperature monitoring units 40 connected by the daisy chain to the same transmitting / receiving unit 18 of the main body controller 10 can be identified by a unique ID code. Is stored in the ROM for the ID code included in the serial output temperature sensor IC and cannot be changed. Therefore, it is not possible to assign an arbitrary ID code for easy management when constructing the system,
It takes a lot of time and effort to manage information (which will be referred to as “location information”) indicating where the temperature is being measured by the temperature monitoring unit 40 having each ID code.

Therefore, in this embodiment, as shown in FIG. 17, the temperature monitoring unit 40 ₁ directly connected to the main body controller 10 is the first temperature monitoring unit 4 and the first temperature monitoring unit 4 is the temperature monitoring unit 40 _1.
The temperature monitoring unit 40 ₂ directly connected to 0 ₁ is defined as the _{second one} in order, and the ID code and connection order of the plurality of temperature monitoring units 40 ₁ , 40 ₂ , ... In this way, the management of the location information is simplified by managing the plurality of temperature monitoring units 40 according to the connection order to the main body controller 10 instead of managing the plurality of temperature monitoring units 40 with the ID code.

Next, the procedure for acquiring the ID code and connection order of the temperature monitoring units 40 ₁ , ... In this embodiment will be described. First, when the system first starts up, the control unit 11 of the main body controller 10 transmits a search ROM command to connect the temperature monitoring unit 40 to the communication cable 8.
Perform the work to acquire the ID code of ₁ , ... Here, the search ROM command is a command prepared in the measurement control bus system described in the eighth embodiment, and measures and controls the ID codes stored in the ROMs of a plurality of devices connected to the daisy chain. This is a command to be acquired by the device. However, the process of acquiring the ID code by this search ROM command is not the gist of the present invention, and therefore its explanation is omitted.

The search ROM command transmitted from the control section 11 of the main body controller 10 is sent to the _first temperature monitoring unit 40 ₁ via the communication cable 8, but the analog switch section 43 of the temperature monitoring unit 40 ₁ is set to the default. Downstream temperature monitoring unit 4 for off state
It is not relayed to 0 ₂ ,. Therefore, in the controller 11 of the main body controller 10, the first temperature monitoring unit 40 ₁
Only the ID code of can be acquired, and the acquired ID
The code is registered in the data table of the memory unit 13 as the ID code of the _first temperature monitoring unit 40 ₁ .

On the other hand, in the control circuit section 44 of the _first temperature monitoring unit 40 ₁ , the control section 1 of the main body controller 10
When it is detected that the first search ROM command by 1 is completed, the analog switch unit 43 is turned on. Then, the control unit 11 transmits the search ROM command again, but this time, since the analog switch unit 43 of the _first temperature monitoring unit 40 ₁ is turned on, the search R is performed.
The OM command is relayed to the second temperature monitoring unit 40. Therefore, it is possible to obtain the ID code of the control unit 11 in the second temperature monitoring unit 40 ₂ of the controller body 10, the data in the memory unit 13 the ID code acquired as the second ID code of the temperature monitoring unit 40 ₂ Register in the table. Similarly, the above processing is repeated until no new ID code is detected for the search ROM command, so that the control unit 11 of the main body controller 10 associates the connection order of the temperature monitoring units 40 _i with the ID code. You can get a relationship.
