(Embodiment 1)
This embodiment shows the example which supervises and controls the equipment 2 arrange | positioned in the house with the management apparatus 1, as shown in FIG. Moreover, although the structure which supplies electric power to the equipment 2 using AC power supply, such as a commercial power supply, is shown in the example of illustration, the structure which supplies the electric power used by the equipment 2 from the power supply incorporated in the equipment 2 may be sufficient. Moreover, although the management apparatus 1 is attached to the switchboard 4 which is an electric power supply source, the position which arrange | positions the management apparatus 1 can be suitably selected as mentioned later.

  The management device 1 includes, for example, a liquid crystal display and a switch (may be a touch panel), and is a device that monitors the operation of the equipment device 2 or gives an instruction to the equipment device 1 to operate the microcomputer. Built-in communication is possible. The information on the equipment 2 monitored by the monitoring device 1 includes the voltage and current applied to the equipment 2 or the instantaneous value and integrated value of the power consumed by the equipment 2, the operating state of the equipment 2, the equipment The information that the monitoring apparatus 1 instructs the equipment 2 includes ON / OFF of the equipment 2 and elements (light quantity, temperature, volume, etc.) that the equipment 2 can adjust. In some cases, there are adjustment amounts.

  The equipment 2 is driven by DC power and is connected to electrical equipment for crime prevention and disaster prevention, electrical equipment for recording video and audio data, electrical equipment for outputting video and audio, and a wide area network. It is envisaged to be a communication device, a telephone, an intercom device, etc., an information-related or communication-related electrical device, a monitoring electrical device attached to a lighting fixture, an air conditioner, or the like to monitor the operation. However, as long as it is a communicable device, it may be another electrical device such as a lighting device or an air conditioner driven by AC power.

  The switchboard 4 includes one main breaker BR1 inserted into a main line connected to a commercial power source, and a plurality of branch breakers BR2 respectively inserted into load circuits branched into a plurality of circuits on the load side of the main breaker BR1. Provided as a container. The base device 3 is connected to the branch breaker BR2 via the upper power feed line Lp1. The base device 3 is connected to all branch breakers BR2 that feed power to the equipment 2 via the upper power feed line Lp1. The base device 3 includes, as a power supply unit, an AC / DC converter 12 that converts AC power supplied from the upper power feed line Lp1 to DC power, and the DC power output from the AC / DC converter 12 is lower power feed line Lp2. Is supplied to the equipment 2 via.

  Since the base device 3 is provided with the AC / DC converter 12 and DC power is supplied to the equipment 2, in the equipment 2 driven by DC power, a power supply circuit for converting AC power into DC power Can be operated without installing a power adapter or externally attaching a power adapter for converting AC power to DC power. Therefore, the loss can be reduced as compared with the case where the individual equipment 2 converts to DC power, the conversion efficiency becomes high, and the equipment 2 can be downsized because it is not necessary to incorporate a power circuit. Or, it looks better because there is no exposure of the power adapter.

  The base device 3 has a function of mediating communication between the equipment 2 and the management device 3, and in this configuration example, the upper power supply line Lp1 and the lower power supply for supplying power to the communication line Ls serving as a communication path. It is provided separately from the line Lp2. Further, since the management device 1 is attached to the switchboard 4, the switchboard 4 is provided with a communication path branching unit 10 for branching the information line Ls to each base device 3. The communication path branching unit 10 only needs to have a function of branching the information line Ls to the management device 1 and the communication line Ls Ls to each base device 3, and the management device 1 and the base device 3 are mutually connected. A communication path may be formed. The communication path branching unit 10 in the illustrated example has a function of connecting three information lines Ls in order to connect the two base apparatuses 3 to the management apparatus 1.

  The base device 3 is connected to at least one equipment device 2 via the information line Ls. The equipment 2 that is communicably connected to the base device 3 via the information line Ls becomes the equipment 2 managed by the base device 3, and the equipment 2 under the management of the base device 3 is in this configuration example. Power is supplied from the base device 3 that manages the equipment 2. By supplying power to the equipment 2 managed by the base device 3 through communication, the base equipment 3 collects the communication line Ls and the lower power feed line Lp2 from the managed equipment 2 respectively. This makes wiring construction easier. However, since the power supply path and the communication path to the equipment 2 are separated, it is not essential to supply power from the base device 3 to the managed equipment 2.

  The base device 3 is provided with a communication path branching unit 11 that connects the information line Ls connected to the managed equipment 2 and the information line Ls to the management device 1. The communication path branching unit 11 includes a microcomputer, and not only connects the information line Ls between the management device 1 and the equipment 2 but also performs processing described later, thereby communicating between the management device 1 and the equipment 2. Relay. In addition, the base device 3 includes a management position holding unit 13 that holds management position information indicating an arrangement area of the managed equipment 2, and static information and equipment determined by the type of the equipment 2 with respect to the equipment 2. And a device information holding unit 14 for holding dynamic device information determined by the operation 2.

  The management position information only needs to be able to specify the arrangement area of the equipment 2 and can use the name of the arrangement place. Usually, the base address used by the base device 3 for communication is used as the management position information. In addition, for the convenience of the user, the name of the location (kitchen, bedroom, etc.) and the base address are associated with each other, and when presenting to the user, the landmark of the location is used and the management location holding unit 13 is used. It is desirable to register the base address.

  The static device information means information that does not change during operation of the equipment 2 such as the name of the equipment 2, the equipment address used for communication in the equipment 2, and the rated power of the equipment 2, and the dynamic equipment information is , Information that changes during operation of the equipment 2 such as supply voltage, supply current, supply power, on / off, normal / abnormal. Among the dynamic device information, the voltage, current, power, etc. are stored in the device information holding unit 14 in association with each facility device 2, and the maximum value, the total value, the average value, and the integrated value may be stored. . In addition to storing both static device information and dynamic device information, the device information holding unit 14 may store only one of them.

  It is desirable to use a non-volatile memory for the management position holding unit 13 and the device information holding unit 14 so that the held contents can be rewritten and the held contents are not lost even during a power failure. Information stored in the management position holding unit 13 and the device information holding unit 14 is acquired by communication with the equipment 2.

  Since the base device 3 acquires and holds the static device information and the dynamic device information by providing the device information holding unit 14, the management device 1 acquires the static device information and the dynamic device information related to the equipment device 2. In acquiring the device information, it is possible to acquire information related to the facility device 2 managed by the base device 3 only by communicating with the base device 3. If this configuration is used, for example, after the base device 3 acquires information about the equipment 2 in advance, the management device 1 adopts an operation of communicating with the base equipment 3, so that the management device 1 is individually connected to the equipment 3. Compared with the case where the same information is acquired by communicating with, the traffic between the management device 1 and the base device 3 can be reduced.

  By the way, in the illustrated example, a plurality of (two) base devices 3 are provided, and information filters 15 for selecting permission and block of communication are provided on the information line Ls between the management device 1 and each base device 2. It has been. In this configuration example, the information filter 15 is built in the base device 3, but the information filter 15 can be arranged separately from the base device 3. The permission and prevention of communication by the information filter 15 is instructed by the management device 1 through the information line Ls. The permission and blocking of the information filter 15 may be selected by operating a manual switch provided in the base device 3 or giving a selection instruction from the management device 1 to the information filter 15 through a dedicated control line. Is possible.

  As described above, since the information filter 15 is provided for each base device 3, the management device 1 can select communication permission and block for each base device 3. Here, even if no communication address is set in the base device 3, the management device 1 is identified by restricting the communication path between the management device 1 and the base device 3 by the information filter 15. It is possible to communicate only with the base device 3 of

  As for the control of the information filter 15, in addition to selecting permission of communication for each base device 3, starting from a state in which the information filter 15 in all base devices 3 is passed or blocked, it is passed or blocked. The information filters 15 in the state may be reduced one by one.

  FIG. 2 shows a connection relationship in which the details of the base unit 3 and the switchboard 4 are omitted for the configuration shown in FIG. As is apparent from FIG. 2, the distribution board 4 is provided with a communication path branching unit 10 that branches the information line Ls that is a communication path between the management device 1 and the equipment 2, and the base unit 3 has the information line Ls. Is further provided with a communication path branching section 11 that further branches In addition, the switchboard 4 distributes power, and each base unit 3 also distributes power to each facility device 2. The switchboard 4 and the base device 3 are connected by an upper power feed line Lp1, and the base device 3 and each facility device 2 are connected by a lower power feed line Lp2. In addition, an information filter 15 is inserted in each information line Ls between each base device 3 and the management device 1. In FIG. 1, the information filter 15 is built in the base device 3, but in the configuration example shown in FIG. 2, the information filter 15 is provided separately from the base device 3. The lower power feed line Lp2 and the information line Ls that connect the base device 3 and the equipment 2 are preferably branched in the base device 3, but are arranged in an area specified by the management position information of the base device 3. 2, as shown in FIG. 2, a part of the lower feed line Lp <b> 2 and the information line Ls can be branched outside the base device 3.

  When communicating between the management apparatus 1 and the equipment 2, identification information of the equipment 2 is required. In this configuration example, when specifying the equipment 2, not only the equipment address set in the equipment 2 to be used for communication but also the base address indicating the arrangement area of the equipment 2 in the base device 3 is used together. Use. The device address is an address that is uniquely set for the facility device 2, and usually a different device address is set for each facility device 2. However, the address may be a unique (unique) address under the management of the base device 3. The base address is a unique address under the management of the management apparatus 1. Therefore, when the management apparatus 1 communicates with the equipment 2, the equipment 1 can be individually identified by using a combination of the base address and the equipment address as equipment information for specifying the equipment 2. Moreover, by including the base address in the identification information, the management apparatus 1 can collectively manage the equipment 2 provided under the management of the base apparatus 3 in units of the base apparatus 3.

  There are the following two types of methods for combining the base address and the device address. In the first procedure, the equipment address is transmitted to the base equipment 3 when the equipment 2 communicates with the base equipment 3, and the base equipment 3 receives the equipment address from the equipment 2 and adds the base address to the equipment address. Identification information is generated, and this identification information is used for communication with the management apparatus 1. That is, when the management device 1 accesses the equipment device 2 and tries to acquire static device information or dynamic device information from the equipment device 2, the management device 1 gives a command to the base device 3, and the base command 3 Transmits the command to the managed equipment 2. In response to this command, the equipment device 2 adds a device address and returns response information, so the base device 3 adds the base address to the device address and returns response information to the management device 1.

  In the first procedure, the equipment address and the base address are combined in the base device 3 by sending the equipment address from the equipment 2 to the base device 3, but in the second procedure, the equipment is connected from the base device 3 on the contrary. By sending the base address to the device 2, the base address and the device address are combined in the equipment device 2. This work is preferably performed by the base device 3 communicating with the equipment 2 under management in advance. In the equipment 2, the base address and the equipment address are combined and held as identification information, and the held identification information is used for communication with the management apparatus 1.

  If the first procedure is adopted, it is not necessary to manage the base address in the equipment device 2, so that an increase in the load on the equipment device 2 can be prevented. Further, if the second procedure is adopted, the base address and the device address are previously combined at the time of construction or the like, so that each time the management apparatus 1 monitors the equipment 2, the base address and the device address are changed. Therefore, the internal processing of the base device 3 is simplified and the communication speed is increased.

(Embodiment 2)
In the first embodiment, an example in which the communication line Ls is provided separately from the upper feed line Lp1 and the lower feed line Lp2, but in this example, as shown in FIG. 3, the upper feed line Lp1 and the lower feed line Lp2 Is also used as a communication path. That is, communication between the equipment 2 and the base device 3 transmits information using the lower power feed line Lp2 as a communication path. An information signal for transmitting information uses a high-frequency carrier wave, which is superimposed on the AC voltage in the upper power supply line Lp1 and superimposed on the DC voltage in the lower power supply line Lp2.

  Further, in this example, the management device 1 is provided as the equipment 2 of one base device 3 (the base device 3 in FIG. 3) instead of the switchboard 4. However, the management apparatus 1 does not communicate directly with the equipment 2 connected to the same base equipment 3, but communicates with other equipment 2 via the base equipment 3. The equipment 2 provided under the management of the base device 3 to which the management device 1 is not connected communicates with the management device 1 via the two base devices 3 using the upper power feed line Lp1 as a communication path. Although it is (that is, the upper power feed line Lp1 is included in the communication path), the base device 3 to which the management device 1 is connected has a function of simply passing information through this route.

  The information filter 15 is inserted between each base device 3 and the switchboard 4 as in the first embodiment. However, in this example, the information filter 15 is inserted not in the information line Ls but in the upper feed line Lp1. Yes. This information filter 15 uses an AC power that passes through regardless of whether communication is permitted or blocked. Specifically, a configuration for selecting whether or not to insert a low-pass filter into the upper power feed line Lp1, or a circuit that separates and synthesizes AC power and information signals supplied from the upper power feed line Lp1 using a capacitor or an inductor. A configuration in which communication is permitted and blocked in the route after separation can be employed. In the present embodiment, the upper power feed line Lp1 and the lower power feed line Lp2 are also used as communication paths, and therefore the communication path branching section 11 is provided inside the AC / DC converter 12 as a power supply section. However, when providing a circuit that separates and combines AC power and information signals as described above, the communication path branching unit 11 can be provided separately from the AC / DC converter 12.

  Other configurations and operations are the same as those of the first embodiment, and in the configuration of the present embodiment, the upper power feed line Lp1 and the lower power feed line Lp2 are also used as communication paths. It becomes possible to save construction.

(Embodiment 3)
As in the second embodiment, the present embodiment shows an example in which the upper power feed line Lp1 and the lower power feed line Lp2 are also used as communication paths. By the way, in the above-described embodiment, a group of equipment 2 is connected under the control of one base apparatus 3, but in this example, as shown in FIG. A plurality of groups of equipment devices 2 can be connected to 2. In addition, information filters 16 are inserted in the lower power feed lines Lp2 connecting the equipment devices 2 of each group. The information filter 16 has the same function as the information filter 15, but the information filter 16 is selected to be permitted or blocked when the equipment 2 is accessed separately for each group.

  Each information filter 16 preferably has a base address. If the base address is held in the information filter 16, the base address is selected by selecting the information filter 16. That is, the management device 1 can alternatively select a base address and monitor or control the equipment 2 for each group. That is, the configuration of the present embodiment can be used similarly to the first embodiment.

  Other configurations and operations of the present embodiment are the same as those of the other embodiments described above, and in the present embodiment, a single base device 3 can manage a plurality of groups of equipment 2, for example, When there are multiple types of equipment 2 in the room and you want to monitor and control the equipment 2 for each type, the equipment 3 can be selected with a single base equipment 3 while providing the base equipment 3 for each room. It becomes possible to monitor or control separately.
