Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building group management system, and more particularly to a building group management system in which a parent building management system monitors and controls equipment of a child building management system using an interface device.

[0002]

2. Description of the Related Art FIG. 12 shows, for example, Mitsubishi Electric Technical Report Vol.
63 No. 6 June 1989 issue, P53-P58
It is a block diagram which shows the building group management system in the prior art shown by "Marunouchi renewal building group management system."

A conventional building group management device is composed of the following devices. 40: “M-CPU (group management center)” having data server function and man-machine function of parent building management device 41: This switching by “control right switch” connected to M-CPU (group management center) The switch switches the control right whether the control right is from the parent building or the child building.

42: "B-CPU (building management center)" having data server function and man-machine function of child building management device 43: Control output / fault detection and measurement / measurement of equipment installed in plural in a building "L-CPU (local management device)" to be performed 44: One is installed in each child building and exchanges monitoring control data with a local bus connecting the L-CPU.
-"FEP (Front End Processor = communication control processing device)" for exchanging necessary information with CPU and B-CPU 45: Sub-building equipment

Next, the operation will be described with reference to FIG. When the state change or failure of the equipment of the child building occurs,
The L-CPU 43 detects this and notifies the FEP 44 of change information together with the internal address number of the device. FEP
44 receives the change information from the B-CPU 42, M-CP
Send to U40.

The B-CPU 42 and M-CPU 40 are FE
An alarm is sounded and CRT is automatically displayed according to the change information from P44 to notify the operator of a change in the state of equipment or a failure. When the child building equipment is controlled by both the M-CPU 40 and the B-CPU 42, the control operation is restricted by the control right changeover switch 41 connected to the M-CPU 40. The M-CPU 40 notifies the state of the control right changeover switch 41 to the B-CPU 42 via the FEP 44.

The transmission / reception of the monitoring / control information as described above is carried out based on an internal address. This internal address is assigned to each device of the sub-building equipment, and is a number for identifying each device ( (Identification symbol). This internal address is commonly used for the entire building management device. That is, the building name of the target device (building classification number, 001,002
Etc.), the name of the target device (ABC1, ABC2, etc.), the classification of the L-CPU 43 of the target device (LCP1, LCP2, etc.)
You are. The monitoring / control signals are change information such as start / stop (0001 is started / 0002 is stopped, etc.), failure occurrence / failure recovery, and input ON / OFF.

[0008]

In the prior art, FE is used.
P44 is M-CPU40, B-CPU42, and L
-Because it is connected to the CPU 43, the state signal from the L-CPU 43 is distributed to both the M-CPU 40 and the B-CPU 42, or the device control signal from the M-CPU 40 is transmitted only to a predetermined L-CPU 43, It is necessary to perform transmission / reception processing of various patterns according to the signal content, such as not transmitting to the B-CPU 42, and the functional structure is complicated.

Further, the M-CPU 40 and the B-CPU 42
Therefore, it is necessary to register the same internal address. For example, even if the M-CPU 40 wants to monitor only the representative signal of each building, it is necessary to register the internal address even to the equipment not to be monitored, which is wasteful. Further, there is a problem that the capacity of the M-CPU 40 as well as the B-CPU 42 is limited by the capacity of the FEP 44.

That is, in the prior art, since only one internal address number of a certain equipment is defined on the system, it is detected by the L-CPU 43 and does not change even if it goes to the M-CPU 40. Monitoring and control operations in the parent building and child building are exactly the same (all devices that can be monitored and controlled in the child building are
You can monitor and control even from the parent building. In the case of), the conventional technology may be used, but in reality, "I want to monitor and control only the representative equipment of each building in the parent building." In most cases, it is not necessary to measure the temperature.

In this case, it is not necessary to define the same data as the child building in the parent building, and there is an advantage that the data can be made smaller if the internal address numbers are eliminated and the numbers are renumbered. come.

The present invention has been made in order to solve the above-mentioned problems, and the internal addresses of the parent building / child building are made independent of each other and are converted between the two addresses so that the entire group management device The purpose is to make the configuration efficient and flexible. Also, by separating the communication function between the parent building and the child building, which used to rely on the signal distribution function of FEP, to the interface device (CIP), the function of FEP can be simplified and the reliability can be improved. The purpose is to make the configuration of the entire management apparatus flexible.

Corresponding to "M-CPU" of the parent building in the child building
Has the same function as. 3 is an interface device (CIP = Co) that realizes a group management device by connecting a parent building and a child building.
munication Interface Proccessor).

Next, the operation will be described with reference to the flowchart of FIG. When a state change or failure of the equipment 25 of the child building occurs (step S1), the L-CPU of the child building
23 detects this, and notifies the FEP 24 of change information together with the internal address number of the device (step S2).
The FEP 24 receives the change information and the internal address from the L-CPU 23, transmits the change information and the internal address to the data bus 22, and B-C.
The PU 21 and the interface device 3 are made to be able to receive this change information (step S3).

The B-CPU 21 receives the change information and the internal address from the data bus 22 and sounds an alarm and automatically displays the CRT to notify the operator of the state change of the equipment and the occurrence of a failure (step S4).

At this time, the interface device 3 receives the change information and the internal address from the data bus 22,
After converting the internal address number of the child building facility device to the internal address number of the parent building, the M-CPU 11 transmits the internal address number to the parent building side data bus 12 (step S).
5).

The M-CPU 11 is the parent building side data bus 1
The change information and the converted internal address number are received from 2 and processed in the same manner as the state change / fault occurrence of the equipment of the parent building, and an alarm ringing / CRT automatic display is performed (step S6). In this way, the status / fault monitoring of the equipment of the child building is realized from the parent building.

Next, the interface device 3 is shown in FIG.
The configuration and functions will be described based on the above. The interface device 3 is composed of the following blocks as shown in FIG. 31: “Transmitting / receiving unit” for transmitting / receiving data to / from the parent building side data bus 12 32: “Address converting unit” for converting internal address included in device change signal 33: Internal device address of facility device of child building, "Child building-> parent building address conversion table section" that records a comparison table for converting the address of the child building to the address of the parent building 34: "Transmission / reception section" for transmitting / receiving data to / from the child building side data bus 22

Next, the operation will be described. When the state change or failure occurs in the sub-building equipment, the interface device 3 receives the change information from the sub-building side data bus 22 by the transmitting / receiving unit 34 and transfers it to the address converting unit 32.

The address conversion unit 32 uses the internal device address of the device included in the transferred change information as an internal address of the parent building based on the comparison table recorded in the child building → parent building address conversion table unit 33. It is converted into a device address and transferred to the transmission / reception unit 31. The transmission / reception unit 31 sends the change information transferred from the address conversion unit to the parent building side data bus 12.

As a result, the parent building management device 1 can receive the change information of the state change / fault occurrence of the equipment of the child building in the same manner as the state change / fault occurrence of the equipment of the parent building and perform the alarm process. It is possible. FIG. 4 is a summary of the overall signal processing operation described above.

Here, the address will be described. The internal address of the parent building is numbered so that it can be easily managed when monitoring and controlling the child building from the perspective of the parent building, and the internal address of the child building side is numbered so that it can be managed independently for each child building. It

For example, the address is displayed with the following 7 digits. Address number = ********* If this 7-digit address number is set to address number = ABCDEFG, A = FE connected to each data bus of the parent building and child building
P and CIP numbers BC = number of each FEP channel DE = number of L-CPU handling the signal of the device in each channel FG = identification of device / signal in each L-CPU Assign numbers and assign numbers.

Therefore, the internal address on the child building side can be determined for each equipment device of the child building equipment 25, while the internal address of the parent building uniquely identifies which child equipment and equipment signal is from which child building. Can be decided. For example, the addresses are numbered as follows. Then, the child building address is associated with the parent building address, and this is registered in the child building → parent building address conversion table unit 33 shown in FIG. Child building address -----> Parent building address 0005128 -----> 1101001 0000301 -----> 2000001 0000502 -----> 2000002 1100010 -----> 2000210

As an easy-to-understand example, the building is identified and numbered as follows. For device 11 of building A, for device 12 of building A, for device 12 of 100002 building B, for device 22 of 200001 building B, for example 200002 Since identification is performed, the internal address of the parent building may be the same address number as the child building address. In this example, the address number is changed for each building, but since the child building is identified on the parent building side, it is possible to freely assign the same address number among the child buildings.

The change information and failure information of the sub-building equipment are
It is transmitted together with the internal address as transmission data.
This transmission data includes, for example, equipment operation / shutdown, failure occurrence / recovery, fire occurrence, etc., input on or input off, change cause code, automatic control, operator operation, etc. It is assigned to a predetermined digit and sent together with the internal address.

Therefore, when data is transmitted from the child building to the parent building, the data of the child building equipment and its internal address are transmitted from the child building side, and the interface device (CI) is used.
P) 3 refers to the child building → parent building address conversion table section 33, converts the address in the address conversion section 32, transmits the internal address of the parent building and data, and the parent building side based on this transmission data. Monitor.

As described above, according to the first embodiment of the present invention, the address on the parent building side and the address on the child building side are separated, and the internal address of the child building is managed independently for each child building. The parent building's internal address is numbered so that it is easy to manage the parent building and each child building, and
When the data is transmitted between the parent building and the child building, address conversion is performed, which facilitates management in each building. Further, since only the data necessary for monitoring from the parent building is subjected to the address conversion, the conversion process is not wasted and the conversion table can be made small, so that the memory capacity can be small.

Embodiment 2 In the first embodiment, the case where the parent building management device 1 monitors the state of the equipment of the child building has been described. However, in this embodiment, the work such as maintenance and testing of the equipment is performed in the child building. When the parent building does not need to monitor the equipment of the child building, the equipment of the child building can be suppressed from being monitored.

As shown in FIG. 5, the interface device 3
A state change suppression setting table 35 is provided to suppress the address conversion / data transfer function of the interface device 3 from the parent building management system.

This deterrent means is for each sub-building facility equipment unit,
That is, it is suppressed in address units, and is usually realized on the software of the interface device 3 by an operator's instruction from the parent building side (or child building side). That is, by specifying the address number to be suppressed together with the suppression signal (suppression function ON signal), the data is stored in the status change suppression setting table 35, and when the signal of the stored address is received, the transmission of the data is blocked. To do.

Even in the inhibited state, the parent building management device 1 and the child building management device 2 can monitor and control the equipment of the own building without interruption. Further, although the suppression can be performed on an address-by-address basis, it is also possible to specify the range of the address or to specify only the upper digits of the address to collectively suppress.

Although this deterrent operation can be realized by means other than software, for example, it is difficult to realize because it requires switches and the like for the number of addresses, and the cost becomes high. To turn the deterrent function from on to off, transmit the "deterrent function off" signal and address number to switch it off.

FIG. 6 is a summary of the overall signal processing operation described above. As described above, in this embodiment, signal suppression can be easily performed in address units.

Embodiment 3. In the first and second embodiments, the case where the parent building management apparatus 1 monitors the state of the equipment of the child building has been described, but this embodiment enables the parent building management apparatus 1 to control the equipment of the child building. It is a thing.

As shown in FIG. 7, the interface device 3 is provided with a parent building → child building address conversion table section 36, and the parent building side address is converted to the child building side address by the procedure reverse to the state monitoring, and the parent building side address is converted into the parent building side address. The building management apparatus 1 controls the equipment of the child building.

At this time, since the interface device 3 converts the parent building side address into the child building side address, and directly notifies the FEP of the child building of the control request via the child building side data bus, the child building management device. The control output is performed from the L-CPU as in the case where the control operation is performed from 2 itself.
As in the first embodiment, the control result is notified to the parent building,
Can be monitored. The structure of the parent building-> child building address conversion table section 36 is the reverse of the child building-> parent building address conversion table section 33.

FIG. 8 is a summary of the overall signal processing operation described above. As described above, in this embodiment, a control signal can be transmitted from the parent building side to the child building to control the child building equipment.

Embodiment 4 FIG. In this embodiment, in addition to the third embodiment, the control right is switched whether the control on the child building side is controlled from the parent building or from the child building.

In this embodiment, as shown in FIG. 9, the interface device 3 has a control right changeover switch 37 and a P switch.
By providing an I / O unit (process input / output unit) 38 and reading the setting state of the control right changeover switch 37, only one of the parent building management device 1 and the child building management device 2 is an equipment device of the child building. It is intended to limit the control of.

With this function, it is possible to prevent adverse effects such as repeated start / stop due to controlling the same device from a plurality of places. The control right switching device is installed in the parent building management device 1 or the child building management device 2 according to the operation. FIG. 10 is a summary of the overall signal processing operation described above.

A method of realizing control right switching will be described below. Based on the input signal of the control right switch device 37, the interface device 3 determines which of the parent building management device 1 and the child building management device 2 has the control right,
This is notified to both building management devices. When the parent building management device 1 and the child building management device 2 perform a control input operation, according to the notification of the presence or absence of the control right from the interface device 3, if there is no control right, the control input is discarded.

For example, when an abnormality occurs in the interface device 3, the child building management device 2 automatically determines that the child building management device 2 has the control right when the abnormality is detected in the interface device 3, It enables the control operation of. Further, at this time, since the control request from the parent building management device 1 is not output to the data bus of the child building,
Control restrictions can be continued.

The detection of the occurrence of an abnormality in the interface device 3 generally has a response from the transmission destination during signal transmission. If there is no response, it is considered that the interface device 3 has failed and the child building management device 2 side Manage with. It should be noted that the control right is switched not only when the interface device is abnormal but also when another condition requiring the control right is generated. The control right can be switched by an operator from the parent building side or the child building side.

As described above, in this embodiment, the control right can be switched to either the parent building or the child building.

Embodiment 5 FIG. In the first embodiment, address conversion from the child building side to the parent building side is performed, in the second embodiment, monitoring signal suppression means is added to the first embodiment, and in the third embodiment, parent device is added to the second embodiment. In the fourth embodiment, the address conversion from the building side to the child building side is performed by switching the control right in addition to the third embodiment, but the first embodiment is combined with the address conversion of the third embodiment. Alternatively, the switching of the control right according to the fourth embodiment may be combined.

The interface device may be installed in the parent building management device or may be installed in the child building management device.

Embodiment 6 FIG. Embodiments 1 to 4 above
Both have a building connected by the interface device 3 as a parent-child relationship of “parent building” and “child building”.
Although the supervisory control of the equipment of the child building has been described, the status / fault change notification and the control request of the equipment of the building connected in the interface device 3 are converted into addresses and notified to the other building for connection. It is possible for the building to monitor and control the equipment of the other building on the standpoint of each other rather than the parent-child relationship.

FIG. 11 is a summary of the signal processing operations of the above-described equal buildings, where the upper half of the figure monitors and controls the A building to the B building, and the lower half of the figure shows the B building to the A building. This is the case of monitoring and controlling. Although the control right switching means is not shown in this drawing, the control right may be switched as in the fourth embodiment.
