Description

[Technical field]

[0001] The present invention relates to a control panel that houses a controller for monitoring or controlling various devices, and a control and monitoring system that monitors or controls various devices via the controller. [Background technology]

[0002] In recent years, the rising cost of materials and labor has become a problem in building and equipment control and monitoring systems. Equipment used in building control and monitoring systems is required to be low-cost and easy to install. In terms of installation, it may seem effective to eliminate wiring because there are many sensors, but in reality, the construction of long, heavy wiring called trunk lines is a heavy burden and should be eliminated.

[0003] FIG. 7 is a diagram outlining conventional building facilities. Multiple control panels 1 are installed on each floor of a building. These multiple control panels 1 are connected to each other by horizontal trunk lines. Multiple controllers are placed inside the control panel 1, and each controller is connected to each other by wires. Devices 2 to be controlled or measured are connected to the control panel 1 by wires, and receive power from the control panel 1 and communicate with the control panel 1. The controllers of the control panel 1 control the devices 2 in the target area or collect data measured by the devices 2. Information from each device 2 is collected in the building's central control room (not shown) via the control panel 1 by trunk lines that vertically connect the network wiring on each floor.

[0004] 8 is a diagram for explaining the configuration of vertical and horizontal trunk lines of a conventional building facility. As described above, a plurality of control panels 1 are installed on floors 3-1 to 3-X of the building from the first floor to the Xth floor (X is an integer of 2 or more). A plurality of controllers 100 and a switching hub 101 are arranged inside each control panel 1. The controllers 100 in the control panel 1 are connected to each other via the switching hub 101 and a cable 102. The switching hubs 101 of multiple control panels 1 on the same floor are connected to each other via a cable (horizontal trunk line 4).

[0005] A central monitoring device 500, a monitoring PC (Personal Computer) 501, and a switching hub 502 are arranged in the central control room 5. The central monitoring device 500 and the monitoring PC 501 are connected to the switching hub 502 via a cable 503. The switching hub 101 of the control panel 1 on each floor and the switching hub 502 in the central control room 5 are connected via a cable (vertical trunk line 6).

[0006] 9 is a diagram showing an example of the internal configuration of the control panel 1. Inside each control panel 1, in addition to a controller 100 and a switching hub 101, a power distribution circuit 103 is arranged. Power is supplied to the control panel 1 from the outside via a power cable 7, and power is supplied to each controller 100 via the power distribution circuit 103 and a power cable 104.

[0007] FIG. 10 is a diagram explaining the connection between the control panel and the sensor. On one floor, multiple control panels 1 are installed depending on the scale of the facilities. To streamline the wiring length and optimize the scale of the control panel 1, the area covered by one control panel 1 is limited. The controller 100 of each control panel 1 collects data measured by the sensor 8 (device 2 in FIG. 7) of the target area managed by the control panel 1. A sub-controller 9 is placed between the control panel 1 and the sensor 8. The control panel 1 is often placed in a dedicated area such as a machine room. On the other hand, the sub-controller 9 is often placed in the ceiling space near the sensor 8.

[0008] As mentioned above, thick, long, and heavy cables called trunk lines are required around the control panel, and there was a problem that the installation of the wiring was very time-consuming. In particular, the installation of vertical trunk lines connecting each floor from top to bottom requires more work, time, and cost the higher the building. In addition, the price of the wiring itself is expensive, so the higher the building, the higher the material costs.

[0009] One method for reducing the amount of work required is to apply wireless technology that eliminates the need for wiring. For example, the technology disclosed in Patent Document 1 wirelessly transmits a status signal from an electric lock device installed on the door to a control panel. Making the connection between the sensor and the control panel wireless in this way has the following advantages: (I) it allows for layout freedom, (II) it eliminates the need for wiring work, and (III) it also eliminates the need for wiring materials.

[0010] However, wireless communication can bring new problems that can become an obstacle to widespread adoption. Specifically, there are issues such as the additional cost required to equip sensors with wireless communication functions, and the need to replace the batteries used to power the sensors. This issue becomes more pronounced when there are many sensors at the end of a control and monitoring system, and the disadvantages of eliminating wiring often outweigh the advantages.

[0011] The wiring between the control panel and the sensor installed on the same floor is often limited to a certain area centered on the control panel, and there is no long-distance wiring. In addition, wiring is usually performed using general-purpose cables that are thinner and lighter than the cables used for trunk lines, and the benefits of going wireless in terms of reducing material costs are small. Furthermore, in addition to wireless information and communications, unless the power supply is also made wireless, construction will not be saved. For this reason, wireless sensors are often equipped with batteries, but as the batteries wear out, they need to be replaced. When there are many sensors at the end of a control and monitoring system, changing the batteries in the sensors becomes a major burden for maintenance, and in some cases this can be problematic after the system is introduced.

[0015] Furthermore, one configuration example of the control panel of the present invention further includes a switching hub configured to relay communication between the controller and the first wireless communication device, wherein the switching hub transfers data received via a wired connection from the controller in the panel itself or data received via a wired connection from another control panel connected to the switching hub to the first wireless communication device, and the first wireless communication device transmits via a wired connection data received wirelessly from the central monitoring device to the controller in the panel itself or the other control panel, and the first wireless communication device wirelessly transmits the data transferred from the switching hub to the central monitoring device and transmits the data wirelessly received from the central monitoring device to the switching hub.

Effect of the Invention

[0017] According to the present invention, when a control and monitoring system is introduced into a building or factory, if the communication between all control panels and the central monitoring device is made wireless, the vertical trunk lines connecting the control panels on each floor and the horizontal trunk lines connecting the control panels on the same floor can be eliminated, and thick, heavy, and long wiring is not required, thereby reducing the effort, time, and cost required for wiring construction.

[0019] [First Example] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a diagram showing the configuration of a control and monitoring system according to a first embodiment of the present invention. The control and monitoring system comprises a plurality of control panels 1a arranged on floors 3-1 to 3-X of a building, from the first floor to the Xth floor (X is an integer of 2 or more), and a central control room 5a.

[0020] FIG. 2 is a diagram showing the configuration of a control panel 1a of this embodiment, and FIG. 3 is a diagram showing the device configuration of a central control room 5a of this embodiment. The control board 1 a includes a plurality of controllers 100 , a switching hub 101 , a power distribution circuit 103 , and a wireless communication device 105 .

[0021] The controllers 100 are connected to each other via a switching hub 101 and a cable 102. In addition, each controller 100 is connected to a wireless communication device 105 via the switching hub 101 and the cable 102. Power is supplied to the control board 1a from the outside via a power cable 7. Power is supplied to each controller 100 and wireless communication device 105 via a power distribution circuit 103 and a power cable 104.

[0022] In the central control room 5a, a central monitoring device 500, a monitoring PC 501, a switching hub 502, and a wireless communication device 504 are arranged. The central monitoring device 500 and the monitoring PC 501 are connected to the switching hub 502 via a cable 503. In addition, the central monitoring device 500 is connected to the wireless communication device 504 via the switching hub 502 and the cable 503.

[0023] The wireless communication standard between the wireless communication device 105 and the wireless communication device 504 is, for example, Wi-Fi (registered trademark).

[0024] Next, the operation of the control and monitoring system of this embodiment will be described. The connection between the control panel 1a and the devices under its control, such as sensors, is the same as the conventional configuration shown in Fig. 10, so the symbols in Fig. 10 will also be used in the description of this embodiment.

[0025] The controller 100 of the control panel 1a collects data measured by the sensors 8 in the target section via wired communication through the sub-controller 9. The controller 100 designates the destination of the collected data as the central monitoring device 500 and transmits the data via wired communication to the switching hub 101 in its own panel.

[0026] The switching hub 101 transfers data received from the controller 100 in its own board to the wireless communication device 105 in its own board. The wireless communication device 105 wirelessly transmits data received from the switching hub 101 in its own board to the central monitoring device 500 .

[0027] The wireless communication device 504 in the central control room 5a receives the data wirelessly transmitted from the wireless communication device 105 in the control panel 1a. The wireless communication device 504 transmits the received data to the switching hub 502. The switching hub 502 transfers the data received from the wireless communication device 504 to the central monitoring device 500 .

[0028] The central monitoring device 500 performs a predetermined process on the data received from the switching hub 502. The processes performed by the central monitoring device 500 include, for example, data storage, device monitoring based on the data, device control based on the data, and data transfer to a monitoring PC 501 for data display.

[0029] Each controller 100 may temporarily store the collected data in an internal memory and transmit the data periodically, or may transmit the data when requested by the central monitoring device 500.

[0030] In the above example, data is transmitted from the control panel 1a to the central monitoring device 500, but it goes without saying that data may also be transmitted from the central monitoring device 500 to the control panel 1a. For example, when transmitting data on the set temperature of an air conditioner from the central monitoring device 500 to the controller 100, the central monitoring device 500 sends the data to be transmitted to the controller 100 to the switching hub 502.

[0031] The switching hub 502 transfers the data received from the central monitoring device 500 to the wireless communication device 504 . The wireless communication device 504 wirelessly transmits the data received from the switching hub 502 to the destination controller 100 .

[0032] The wireless communication device 105 of the control board 1a receives the data transmitted from the wireless communication device 504 and transmits it via wired connection to the switching hub 101 in its own board. If the data received from the wireless communication device 105 in its own board is addressed to a controller in its own board, the switching hub 101 transfers the received data to the destination controller 100, and if the data received from the wireless communication device 105 is not addressed to a controller in its own board, the switching hub 101 discards the received data.

[0033] The controller 100 updates the set temperature data of the air conditioner in the target section to the data received from the switching hub 101, and controls the air conditioner so that the indoor temperature in the target section measured by, for example, the sensor 8 matches the set temperature.

[0034] In this embodiment, the case of controlling an air conditioner has been described, but the controlled device does not have to be an air conditioner. In addition, the central monitoring device 500 may perform multicast communication to simultaneously transmit data to multiple controllers 100.

[0035] As described above, in this embodiment, the communication between all the control panels 1a and the central monitoring device 500 is made wireless. In this embodiment, the vertical trunk lines connecting the control panels on each floor and the horizontal trunk lines connecting the control panels on the same floor can be eliminated, and thick, heavy, and long wiring is no longer necessary, so that the effort, time, and cost required for wiring construction can be reduced. This effect is greater in larger facilities. In addition, since expensive wiring is no longer necessary, material costs can also be reduced. On the other hand, since many devices are mounted on the control panel 1a, it is difficult to battery-power devices such as controllers mounted in the control panel, and power is generally supplied from an external source via a wire. Therefore, the power consumed by wireless communication does not become a problem. If the communication between the control panel and the sensor is made wireless as in the past, battery replacement of the sensor becomes a heavy burden on maintenance, and the effort, time, and cost required for maintenance increase.

[0036] [Second Example] 4 is a diagram showing the configuration of a control and monitoring system according to a second embodiment of the present invention. The control and monitoring system of this embodiment is composed of a plurality of control panels 1, 1b arranged on floors 3-1 to 3-X of a building, from the 1st floor to the Xth floor, and a central control room 5a.

[0037] In this embodiment, only the vertical trunk lines connecting the control panels on each floor are eliminated, and the control panels on the same floor are connected by a horizontal trunk line 4. The configuration of the control panel 1 is the same as that shown in Fig. 9, and the device configuration of the central control room 5a is the same as that shown in Fig. 3. The control panel 1b is a representative panel that represents multiple control panels on the same floor and communicates with the central monitoring device 500. The configuration of the control panel 1b is the same as that of the control panel 1a shown in Fig. 2, so it will be explained using the symbols in Fig. 2.

[0038] Next, the operation of the control and monitoring system of this embodiment will be described. The connection between the control panels 1, 1b and the devices under their control, such as sensors, is the same as the conventional configuration shown in Fig. 10, so the symbols in Fig. 10 will also be used in the description of this embodiment.

[0039] The controller 100 of the control panel 1b collects data measured by the sensors 8 in the target section via wired communication, and transmits the collected data to the switching hub 101 in its own panel via wired communication, with the central monitoring device 500 as the destination. The switching hub 101 of the control board 1b transfers the data received from the controller 100 in the board itself to the wireless communication device 105 in the board itself.

[0040] Meanwhile, the controller 100 of the control panel 1 collects data measured by the sensor 8 in the target section via wired communication, and transmits the collected data to the switching hub 101 in its own panel via wired communication, with the central monitoring device 500 as the destination. The switching hub 101 of the control panel 1 transmits data received from the controller 100 in its own panel via a wired connection to the switching hub 101 of the control panel 1b, which is the representative panel on the same floor.

[0041] The switching hub 101 of the control board 1b transfers the data received from the switching hub 101 of the control board 1 to the wireless communication device 105 in its own board. The wireless communication device 105 wirelessly transmits data received from the switching hub 101 in its own board to the central monitoring device 500 .

[0042] The operation in the central control room 5a is as described in the first embodiment. As described in the first embodiment, each controller 100 may transmit data periodically, or may transmit data when requested by the central monitoring device 500.

[0043] In the above example, data is transmitted from the control panel 1, 1b to the central monitoring device 500, but data may also be transmitted from the central monitoring device 500 to the control panel 1, 1b. For example, when transmitting data on the set temperature of an air conditioner from the central monitoring device 500 to the controller 100, the central monitoring device 500 sends the data to be transmitted to the controller 100 to the switching hub 502.

[0044] The switching hub 502 transfers the data received from the central monitoring device 500 to the wireless communication device 504 . The wireless communication device 504 wirelessly transmits the data received from the switching hub 502 to the destination controller 100 .

[0045] The wireless communication device 105 of the control board 1b receives the data transmitted from the wireless communication device 504 and transmits it via wired connection to the switching hub 101 in its own board. If the data received from the wireless communication device 105 in the control panel 1b is addressed to a controller in the control panel 1b, the switching hub 101 transfers the received data to the destination controller 100 in the control panel 1b, and if the data received from the wireless communication device 105 is not addressed to a controller in the control panel 1b, the switching hub 101 transmits the received data via wired connection to the switching hub 101 in another control panel 1 on the same floor.

[0046] A switching hub 101 of another control panel 1 on the same floor transfers the received data to the destination controller 100 in its own panel if the data received via wired connection from the switching hub 101 of control panel 1b, which is the representative control panel on the same floor, is addressed to a controller in its own panel, and discards the received data if the data received from the switching hub 101 of control panel 1b is not addressed to a controller in its own panel.

[0047] The operation of the controller 100 that receives data from the switching hub 101 is the same as that described in the first embodiment.

[0048] In this embodiment, the vertical trunk line can be eliminated, and thick, heavy, and long wiring is no longer necessary, so the effort, time, and cost required for wiring construction can be reduced. In this embodiment, horizontal trunk lines are used as in the past for connections within the same floor, but by eliminating the vertical trunk line, the construction burden can be reduced.

[0049] Furthermore, in this embodiment, wireless communication traffic can be suppressed compared to the first embodiment in which each control panel 1a communicates individually with the central monitoring device 500, and therefore interference and other problems can be reduced. Also, it is necessary to provide wireless communication devices 105 in the same number as the representative panel on each floor, which is significantly fewer than in the first embodiment, and therefore costs can be reduced.

[0050] [Third Example] 5 is a diagram showing the configuration of a control and monitoring system according to a third embodiment of the present invention. The control and monitoring system of this embodiment is composed of a plurality of control panels 1c arranged on floors 3-1 to 3-X of a building from the 1st floor to the Xth floor, a central control room 5c, and a relay device 10 that relays wireless communication between the control panels 1c and a central monitoring device in the central control room 5c.

[0051] In the first and second embodiments, each control board 1c directly communicates with the central monitoring device 500 wirelessly, but in this embodiment, all the control boards 1c are made wireless via public lines. Examples of public lines include LTE (Long Term Evolution), 4G, and 5G.

[0052] The configuration of the control panel 1c is the same as that of the control panel 1a except that the wireless communication standard used by the wireless communication device is different, and therefore will be described using the symbols in Fig. 2. Similarly, the configuration of the device in the central control room 5c is the same as that of the central control room 5a except that the wireless communication standard used by the wireless communication device is different, and therefore will be described using the symbols in Fig. 3.

[0053] Next, the operation of the control and monitoring system of this embodiment will be described. The connection between the control panel 1c and the devices under its control, such as sensors, is the same as the conventional configuration shown in Fig. 10, so the symbols in Fig. 10 will also be used in the description of this embodiment.

[0054] The controller 100 of the control panel 1c collects data measured by the sensors 8 in the target section via wired communication, and transmits the collected data to the switching hub 101 in its own panel via wired communication, with the central monitoring device 500 as the destination.

[0055] The switching hub 101 transfers data received from the controller 100 in its own board to the wireless communication device 105 in its own board. The wireless communication device 105 designates the data transferred from the switching hub 101 in its own board as being destined for the central monitoring device 500, and wirelessly transmits the data to the relay device 10.

[0056] The relay device 10 wirelessly transmits the data received from the control board 1c to the central monitoring device 500, which is the destination.

[0057] The wireless communication device 504 in the central control room 5c receives the data wirelessly transmitted from the relay device 10. The wireless communication device 504 transmits the received data to the switching hub 502. The switching hub 502 transfers the data received from the wireless communication device 504 to the central monitoring device 500. The operation of the central monitoring device 500 is as described in the first embodiment.

[0058] In the above example, data is transmitted from the control panel 1c to the central monitoring device 500. However, data may be transmitted from the central monitoring device 500 to the control panel 1c as in the first and second embodiments. In this case, the central monitoring device 500 sends data to be transmitted to the controller 100 to the switching hub 502.

[0059] The switching hub 502 transfers the data received from the central monitoring device 500 to the wireless communication device 504 . The wireless communication device 504 receives the data from the switching hub 502 and designates the data as being addressed to the controller 100 as the destination, and wirelessly transmits the data to the relay device 10 .

[0060] The relay device 10 wirelessly transmits the data received from the central monitoring device 500 to the destination controller, which is the destination.

[0061] The wireless communication device 105 of the control board 1c receives the data wirelessly transmitted from the relay device 10 and transmits it to the switching hub 101 in its own board. If the data received from the wireless communication device 105 in its own board is addressed to a controller in its own board, the switching hub 101 transfers the received data to the destination controller 100, and if the data received from the wireless communication device 105 is not addressed to a controller in its own board, the switching hub 101 discards the received data.

[0062] The operation of the controller 100 that receives data from the switching hub 101 is the same as that described in the first embodiment.

[0063] In this embodiment, one relay device 10 is used, but it goes without saying that a plurality of relay devices 10 may be provided between the control panel 1c and the central monitoring device 500. In addition, in this embodiment, the relay device 10 is described as being applied to the first embodiment, but it may also be applied to the second embodiment, with the relay device 10 being disposed between the control panel 1b and the central monitoring device 500.

[0064] In addition, in this embodiment, a public line is used for communication between the control panel 1c and the central monitoring device 500, but a private network such as local LTE or local 5G may also be used.

[0065] In the first to third embodiments, the case where an air conditioner is controlled has been described, but it goes without saying that the device to be controlled is not limited to an air conditioner. In addition, in the first to third embodiments, packet communication is assumed for communication between the control panels 1a to 1c and the central monitoring device 500, communication between the switching hub 101 and the controller 100, communication between the switching hub 502 and the central monitoring device 500, and communication between the switching hubs 101, 502 and the wireless communication devices 105, 504, but analog signals may be sent and received between the sensors or controlled equipment and the controller. Furthermore, in the first to third embodiments, the control and monitoring system is applied to a building, but it goes without saying that the system may also be applied to various facilities such as factories.

[0066] Each of the controller 100, the central monitoring device 500, and the monitoring PC 501 described in the first to third embodiments can be realized by a computer equipped with a CPU (Central Processing Unit), a storage device, and an interface, and a program that controls these hardware resources. An example of the configuration of this computer is shown in FIG.

[0067] The computer includes a CPU 200, a storage device 201, and an interface device (I / F) 202. In the case of the controller 100, the sensor 8, the device to be controlled, the switching hub 101, etc. are connected to the I / F 202 by wire. In the case of the central monitoring device 500 and the monitoring PC 501, the switching hub 503, etc. are connected to the I / F 202. In such a computer, a program for realizing the control and monitoring method of the present invention is stored in the storage device 201. The CPU 200 of each device executes the processes described in the first to third embodiments according to the program stored in the storage device 201. [Industrial Applicability]
