In this building management system, the system management computers 2 ₁ and 2 ₂ manage and monitor the entire system, and the autonomous distributed controllers 3 ₁ ... Perform monitoring and control of the respective systems. For example, even if another autonomous decentralized controller system fails, the monitoring and control operation of its own system can be maintained independently. Also, by exchanging data with another autonomous decentralized controller via a LAN,
It can also work in conjunction.

In the case of a small or medium-sized building, a single autonomous decentralized controller 3 monitors and controls a plurality of facilities. By the way, the operation of the conventional autonomous decentralized controller 3 operates mainly on the application program AP as shown in FIG. 11, and includes a processing unit of the network service BA for processing of the LAN, a processing unit of the time division multiplex transmission service NA, and a sur service. When reading / writing data for reading / writing from / to the SL processing unit, management point data, parameter data, and operation data used for control / monitoring, once the application program AP
To be processed and processed, so that the format of each data is
P is in a form that is easy to handle, not a unified form.

[0007] Therefore, since the function upgrade and the line must be performed in pairs of the application program and the data, the influence on other program parts is large, and there is a problem that the function upgrade and improvement are difficult. Note that between the application program AP and the processing units of the services BA, NA, and SL, an event indicating that an event such as setting or detection has occurred is read or written.

FIG. 12 shows a conceptual configuration of the conventional autonomous decentralized controller 3, which comprises a program section for system application functions such as air conditioning control or disaster prevention monitoring, and also defines data necessary for monitoring, control, and operation. And an application platform 100 for each application. Platform 1 by application
Reference numeral 00 denotes a hardware block 101 of the autonomous decentralized controller 3 including a CPU, a memory, a peripheral interface, and the like; an OS (operating system) program unit 102 that enables real-time multitask processing on the hardware block 101; An application program interface including a device driver program unit 103 for controlling an IC, an input / output device, a transmission interface, and the like, and a service program unit for easily controlling and operating the hardware block 101 from the viewpoint of the application program AP. (API) 104. Each of the components 101 to 104 of the platform 100 for each application is designed according to each system application (such as air conditioning or disaster prevention) or each system scale (large, medium, or small). It must be designed separately, and application programs AP with similar processing are created for each application. Further, in order to optimally design the system for a certain specification, a significant change is required when the CPU is upgraded or the input / output interface is changed. Furthermore, it was not the sensation of creating software on a personal computer form, but an image of a personal computer for each application.

[0009]

When a system is configured using an autonomous decentralized controller that operates mainly on an application program as described above, flexibility is poor,
There was a problem that the system could not be easily expanded.
The present invention has been made in view of the above points, and an object of the present invention is to provide a building management system capable of easily expanding a system and having a flexible system configuration.

[0010]

In order to achieve the above object, according to the first aspect of the present invention, a system management computer and an autonomous decentralized controller are connected by a network,
A control terminal for controlling the equipment load and a monitoring terminal for monitoring the state of input elements such as sensors and switches are connected to the autonomous decentralized controller via a control signal line. Do,
In a building management system in which equipment monitoring data and control data are exchanged between the system management computer and the autonomous decentralized controller and between the autonomous decentralized controllers via a network, the autonomous decentralized controller operates and controls hardware. A common platform that standardizes programs to be executed, a common function package that has a function to deliver data to object programs or event data and application programs that process based on the data, It is characterized by having a use-specific package consisting of application programs, and combining each with a common platform, a use-specific package consisting of use-specific application programs, and a common function package. It can be efficiently corresponding to the system, also partial modification or additions can be easily provided building management system.

According to the second aspect of the present invention, the system management computer and the autonomous decentralized controller are connected by a network, and the autonomous decentralized controller monitors the state of input terminals such as control terminals for controlling equipment loads and sensors and switches. Monitoring terminals are connected via control signal lines, and each terminal is monitored and controlled by the autonomous decentralized controller, and equipment is monitored over the network between the system management computer and the autonomous decentralized controller and between the autonomous decentralized controllers. In a building management system in which data and control data are exchanged, the autonomous decentralized controller includes a packaged object sheet, an event sheet, and a control algorithm sheet in which the control process is processed for each function. Device monitoring data In addition, objects such as control data and setting data are stored, the object sheet is rewritten according to the change of the terminal state, and other autonomous distributed controllers or system management registered as notification destinations in the event sheet While transmitting monitoring data and control data according to the change of the state to the computer or both through the network, and when there is an object sheet corresponding to the data sent through the network, rewriting the object sheet and generating an event, The feature is to perform monitoring control corresponding to the corresponding terminal, and by using the object sheet packaged in the autonomous decentralized controller, it is only necessary to add the object sheet when expanding the system,
Therefore, system expansion becomes easy, and flexible system construction becomes possible. In addition, mutual entry and cooperation between the autonomous decentralized controllers by network communication can be efficiently performed by adopting a packaged object sheet. Furthermore, since the control process is packaged for each function, an optimal system can be constructed by combining the function packages, and a system that is just fit for each building can be constructed. The minimum unit of quality can be achieved.

According to a third aspect of the present invention, in the first or second aspect of the invention, the terminal connected to the autonomous distributed controller sends the terminal to the autonomous distributed controller when the system starts up, and the autonomous distributed controller uses the object-oriented database. This feature is characterized by having information for linking to the system, eliminating complicated download adjustment and data merging processing at system startup (initial time) and realizing a so-called plug-and-plug function that only connects terminals. The memory inside the autonomous decentralized controller can be reduced, and as a result, downsizing can be achieved. Further, the system management computer only needs to provide a monitor function, and connection to the system is simplified.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. The overall system configuration of the present invention is shown in FIG.
Since the configuration is the same as that shown in FIG. 1, the configuration of the entire system is not particularly described here, but the system management computer 2 and the autonomous decentralized controller 3 of the present invention are conceptually configured as shown in FIG.

In other words, the system management computer 2 has an OS (for example, Windows-NT (manufactured by Microsoft)) 201 suitable for a network and various application programs 2 such as form issuing, data management, GUI, network management, etc.
02 to 205 are mounted. On the other hand, the autonomous decentralized controller 3 is roughly divided into a common platform 300, a use-specific package 400 including application programs for each use, and a common function package 500, as shown in FIG.

The common platform 300 operates hardware centered on the CPU irrespective of the scale and application.
By standardizing a service pro program (API) to be controlled, for example, by providing a mechanism for performing all data transmission to local transmission (transmission to each terminal 4) by the same program function, it is common to air conditioning systems and disaster prevention systems. It can be used, and this common platform 300
As in the conventional application-specific platform 100 shown in FIG. 8, a hardware block 301 of the autonomous decentralized controller 3 including a CPU, a memory, a peripheral interface, and the like. An OS (Operating System) program unit 302, a device driver program unit 303 that controls a network IC, an input / output device, a transmission interface, and the like, and a hardware block 301 can be easily controlled and operated in view of an application program. And an application program interface (API) 304 including a service program unit for performing the above operation.

The application-specific package 400 is a part of the layer of the conventional application program. The application-specific package 400 constitutes a different program layer depending on the scale and the application, and includes a function-specific processing software unit 401 and an MMI (man-machine interface).
It comprises an application unit 402 and a user programming unit 403. The function-specific processing software unit 401 is configured by a basic function unit in which each module performs BA (building automation), and by combining these modules, defines an air conditioning system and a disaster prevention system. For this reason, software having the same algorithm such as schedule control can be commonly used.

In addition, partial functional upgrades and functional upgrades can be dealt with only by replacing an arbitrary program module, thereby avoiding significant modification and change work. Furthermore, even if hardware components change, application modules for common API can be inherited. The MMI application unit 402 realizes man-machine functions such as air conditioning and disaster prevention by a program used when a man-machine function is added to the autonomous decentralized controller 3 itself, not a control system.

The user programming section 403 is a program module that is operated exclusively for the user request when the user request cannot be realized by a program module prepared in advance in the control system.
Includes programs created outside of. The common function package 500 is a part of the layer of the conventional application program of the related art. However, the common function package 500 constitutes a common program layer irrespective of the size and the use. The network manager section 501 and the APL control algorithm section 50
2. It comprises a GUI (Graphical User Interface) algorithm unit 503.

The network manager unit 501 is provided with standard service software (for example, when data is transmitted to and received from the system management computer 2 via the LAN information line 1 from the application). Software for confirming the arrival at the application level).

The APL control algorithm unit 502 is provided for data existing in the system [LAN, local transmission (multiplex transmission with the terminal 5 via the control signal line 4), inside the autonomous distributed controller 3]. It consists of an algorithm program that controls which module the input data should be output to. The GUI algorithm unit 503 includes:
The structure is substantially the same as that of the APL control algorithm unit 502, but the input / output data to be processed is not an object or an event, but performs man / machine data processing such as key operation input and display output to a liquid crystal display. belongs to.

Here, the APL control algorithm section 50
2 will be described with reference to an example shown in FIG. As shown in FIG. 2, in the INPUT, the temperature data of the on-site temperature sensor 600 connected to the monitoring terminal 5 is input to the APL control algorithm unit 502 through the API 104 by local transmission. APL control algorithm unit 50
Reference numeral 2 denotes a setting for which module of the function-specific processing software unit 401 is to transfer the input temperature data (corresponding to object data to be described later).
In the PUT, the temperature data is passed to the corresponding module. When the temperature data transferred to the function-specific processing software unit 401 notifies the system management computer 2 of an abnormal temperature, event data (actually, an event sheet to be described later) is input to the APL control algorithm unit 502 by INPUT.

In the OUTPUT, the APL control algorithm unit 502 decodes which system management computer 2 should be notified from the data, and sends a transmission request to the network manager 501. The APL control algorithm unit 502 includes such an algorithm, and the actual operation of the system is more complicated, but in short, a mechanism for delivering data to object data or event data and an application program that processes based on the data. It is.

On the other hand, the function-specific processing software unit 401 receives the object data or the event data from the APL control algorithm unit 502 as described above, processes the data with a program module having an arbitrary function, and further performs the processing. When it is necessary to continue the operation, a new internal event occurs, is delivered to the next program module, and has an operation structure in which feedback is applied until necessary processing is completed.

The operation structure of the function-specific processing software unit 401 will be described in more detail with reference to an example shown in FIG. Figure 3 reads the measured data, and when the data exceeds the upper limit data,
The figure shows a case where devices in a set group are controlled. First, an API is read from the monitoring terminal 5a by actual transmission data (for example, room temperature 25 ° C.) from the monitoring terminal 5a by local transmission, that is, multiplex transmission. The actual measurement data corresponds to one object data.
It is delivered to the program module M1 that processes the measurement points such as the temperature of the function-specific processing software unit 401 through the L control algorithm unit 502 (where the delivery is determined by the initial setting).

Program module M for processing measurement points
1 stores this 25 ° C. temperature data in the database 700, and performs comparison processing when upper and lower limit data are set. At this time, if the upper eye data is 24 ° C.,
An internal event is issued as abnormal data occurrence (corresponding to an event control sheet described later).

This event is continuously delivered to the program module M2 that performs interlock monitoring (control). This program module M2 issues a control event to a preset activation group load because an interlocking event has arrived. This control event is delivered to the group operation processing program module M3 for group control, reads necessary devices from the load data table registered in advance in the linked object database 701, and issues an on / off control request.

Upon receiving the control request, the APL control algorithm unit 502 sends a control signal to the control terminal 5b by local transmission through the API 304, and the individual load 80
0 will be controlled. Thus, in the autonomous distributed controller 3 of the present invention, the common platform 300
, Application-specific package 400, and common function package 5
The combination of 00 makes it possible to efficiently cope with various systems, and makes it easy to partially modify and add functions.

Data is exchanged via the AN.

Here, the communication format shown in FIG. 8 is a format type (A) of data such as a message, an event, and a property.
PDU type), data with acknowledgment, data without acknowledgment, service type indicating the meaning of data such as retransmission request, number for recognizing the response to the request (sequential number is assigned on the sending side, and A request identifier consisting of the same number and returning a response), a source object ID [a source device (LAN for transmitting data)
In the case of the autonomous decentralized controller 3, the information includes the information of the identification data of the above device), the object ID of the transmission destination (the identification data of the receiving apparatus that receives the data, etc.), the data length, and the data. It is composed of data representing separation (equipment type data), and actual state data such as temperature, humidity, time, and ON / OFF of a contact (equipment type data). The source object ID includes the equipment type (power, lighting disaster prevention, air conditioning, etc.), the area of the building where the equipment is located, the equipment installation location indicating the location, and the building for managing a plurality of buildings collectively. A number and the like, and an object identification and the like representing a temperature, a humidity, a contact point, and the like are described.

Next, the operation of this embodiment will be described with reference to FIG. For example, from the monitoring terminal 5 ₁ constituting the fire sensor connected to the control signal line 4 ₁ autonomous distributed controllers 3 ₁ which constitutes a disaster control panel has a fire detection information,
Generates update event object sheet S ₁ corresponding to the fire sensor serving monitoring terminal 5 ₁ of fire detection data. In response to this inventory occurrence, it is notified to the notification destination registered in the event enrollment event sheet S ₂ that is associated with the monitoring terminal 5 ₁ (system control computer 2 _1, 2 _2). In response to this notification service, for example, the master system management computer 2 ₁
And A is the system control computer 2 ₂ slaves
The CK or NACK returned to the autonomous distributed controllers 3 _1.
Here, whether or not to use the notification is determined by the receiving side (here, the autonomous distributed controllers 3 ₂ and 3 ₃ ),
The notification side (autonomous decentralized controller 3 ₁ ) simply performs the process specified by the event enrollment.
The operations that are registered in the event the sheet S ₂ of the event control involved in the monitoring terminal 5 ₁ object (autonomous distributed controller 3 ₂ constituting the case equipment control panel, 3 ₃ of the command or object binary output) To the start / stop instruction of the equipment and the equipment group.

Thus, the autonomous distributed controllers 3 ₂ ,

Performs the operation according to the instruction, and returns an ACK for the light property service. In the start / stop instruction, if there is no command or binary output object at the start / stop destination, only an error of the property setting service will occur. Here, since the notification destination of the service error in such an internal interlocking process is unknown, the file object in which the notification destination in such a case is registered may be easily stored in the object sheet. Usually, a system management computer or the like is registered as a notification destination.

As described above, the autonomous decentralized controller 3 of the transmission source rewrites the object sheet S ₁ , notifies the event, and controls the event (interlocking processing such as the start / stop instruction described above).

Meanwhile, the building management facilities interface unit 32, the procedure for the association between the various objects over preparative sheet S ₁ and the control signal line 4 via the corresponding physical terminal information of building management equipment terminal 5 launch system Required before. It is stored in the physical data conversion table 32a - the procedure of mapping from system control computer 2 ₁ ... and to be able Danrodo processed through the LAN, and the results were correlated object data.

(Embodiment 2) An advantage of a system based on object-oriented data as in the present invention is that the system can be easily expanded simply by adding an object sheet when the system is expanded. There are advantages.
For this reason, as shown in the format of FIG. 8, the source object ID includes, in addition to the identification data information of the transmitting device (device on the network) transmitting the data, the area and location of the building where the equipment is located. Information on the installation location of the equipment, building number information for managing a plurality of buildings collectively, and object identification data for managing object data such as temperature, humidity, and contact points are added. In the terminal type data, for example, information indicating whether one piece of temperature information is used for air conditioning or for disaster prevention is written.

By the way, as in the first embodiment, the procedure for associating various object sheets S ₁ with the terminal information of the terminal 5 of the corresponding physical building management facility via the signal line 4 is performed by the system management computer. The method of performing the download processing from 2 ₁ via the network 1 is a complicated operation when the number of objects is large. Therefore, in this embodiment, the autonomous distributed on the rising edge of the system controller 3 system control computer 2 ₁ terminal information
Instead of downloading from…, information is read by data upload from the terminal 5, eliminating complicated download adjustment at the time of initializing, and realizing a so-called plug-and-plug function that only requires connecting the terminal 5. I have.

That is, in this embodiment, as shown in FIG. 9, the object data information table 51 in which the object ID and the equipment type corresponding to the physical No (address) can be freely registered by the external tool 50 is stored in the terminal 5. Have. In addition to the object data information table 51, the terminal 5 includes a local transmission drive circuit 52 for transmitting and receiving communication data in a time division multiplex transmission system, equipment such as a load, and sensors such as a fire alarm sensor and a temperature sensor. Further, an input / output interface circuit 53 for interfacing with the equipment 60 such as an actuator (for example, input / output of contacts, input / output of analog values), converts input data from the equipment 60 into time-division multiplexed communication data, When the terminal address requested by the (autonomous distributed controller 3) is equal to the set value of the address switch 54, the data is returned through the local transmission drive circuit 52, or the terminal address included in the received communication data and the address switch 54 The control data included in the communication data when the set value matches A terminal function processing unit 55 having a function of outputting the output data to the equipment 60, based on,

In the present embodiment, the object ID and the equipment type information are registered in advance in the terminal 5 connected to the system in the object data information table 51 using the tool 50.

When the system is activated, the autonomous distributed controller 3 calls each terminal 5 to return the registered object ID and facility information,
The object data is registered in the object data-physical data conversion table 32a provided in the building facility management interface 32 in association with the (address). That is, the connected terminal 5 can be linked to the object-oriented database.

After the registration process, the terminal 5 returns actual data such as temperature data and contact data, for example, to start normal system operation.

There is an effect that it is possible to efficiently cope with various systems by combining a package for each application and a common function package, and to provide a building management system in which partial correction and addition of functions are easy.

According to a second aspect of the present invention, a system management computer and an autonomous decentralized controller are connected via a network, and the autonomous decentralized controller monitors the status of input terminals such as control terminals for controlling equipment loads and sensors and switches. Monitoring terminals are connected via control signal lines, and each terminal is monitored and controlled by the autonomous decentralized controller, and equipment is monitored over the network between the system management computer and the autonomous decentralized controller and between the autonomous decentralized controllers. In a building management system that exchanges data and control data, the autonomous decentralized controller
Equipped with a packaged object sheet, event sheet, and control algorithm sheet in which the control process is processed by function, and the object sheet stores objects such as terminal monitoring data, control data, and setting data. In addition to rewriting the object sheet according to the change in the state of the terminal, monitoring data and control according to the change in the state are performed by another autonomous decentralized controller or a system management computer registered as a notification destination in the event sheet or both. Data is transmitted over the network, and if there is an object sheet corresponding to the data sent over the network, the object sheet is rewritten, an event is generated, and monitoring and control corresponding to the corresponding terminal is performed. By using a packaged object sheet, it is only necessary to add an object sheet when expanding the system, which facilitates system expansion, enables flexible system construction, and enables autonomous decentralized controllers through network communication. The mutual entry and cooperation between each other can be performed efficiently by adopting a packaged object sheet, and since the control process is packaged by function, the optimal system can be constructed by combining the function packages. It is possible to construct a system that is just fit for each building, and furthermore, it is sufficient to maintain the quality of the software of the process for each package, and it is possible to minimize the quality.

According to a third aspect of the present invention, in the first or second aspect, the terminal connected to the autonomous distributed controller comprises:
When the system is started up, it is sent to the autonomous decentralized controller and the autonomous decentralized controller has information for linking the terminal to an object-oriented database. There is no processing, and a so-called plug-and-plug function that only connects terminals can be realized.
In addition, the memory inside the autonomous decentralized controller is reduced, and as a result, downsizing can be achieved, and further, the system management computer only needs to provide a monitor function, and the connection to the system is simplified.
