Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a control parameter setting device for a building management system, and in particular, to eliminate time delays in control parameter setting operations performed in a central monitoring device and improve responsiveness. The present invention relates to a control parameter setting device suitable for controlling.

[Conventional technology]

Conventionally, the control parameters set by the central monitoring device are transmitted to the terminal devices, and the next setting operation can be performed based on the results of the responses from the distributed terminal devices reaching the central monitoring device.

FIG. 2 is a configuration diagram of a conventional distributed building management system, in which the setting operation permission unit 4 is set to 1. For example, the response processing unit 7 completes the setting based on a response from the distributed terminal device 2a, or the monitoring timer 8 disables the setting. The arrival of the key-in on the display section 9 is a valid condition for key-in. However, due to the transmission line 10, a time delay occurs, resulting in poor responsiveness.

Incidentally, examples related to this type of device include, for example, Japanese Patent Application Laid-Open No. 60-74100.

[Problem to be solved by the invention]

In the above conventional technology, when setting the control parameters, it is essential to confirm by display that the settings have been made correctly.
Generally, it takes time for the control parameters set by the central monitoring device to reach the terminal device and for the response to arrive at the central monitoring device, resulting in the problem of having to wait for the next setting until the response can be confirmed. there were.

An object of the present invention is to allow the next setting by storing the setting operation in a central monitoring device, and to separate the process response by transmission from the setting permission signal for the next process, thereby eliminating time delays. An object of the present invention is to provide a control parameter setting device for a building management system.

[Means to solve the problem]

The above object is to provide a central monitoring device with a setting operation storage section that can store a plurality of setting operations, and to configure the setting operation storage section so that when the setting operation is stored, the next setting operation can be performed.
On the other hand, this is achieved by extracting the setting operation stored in the setting operation storage section and transmitting it to the terminal device.

When a response from the terminal device is received, the setting operation stored in the setting operation storage section is deleted, and the memory of the setting operation storage section is monitored by a monitoring timer, and if the setting operation remains after a predetermined time, Display a warning.

[Effect]

The central monitoring device is equipped with a setting operation storage unit that can store multiple setting operations, and when stored in this storage, the next setting operation can be performed, and the stored setting operations can be retrieved and transmitted one after another. The transmission and response of operations can be separated, reducing the time required for setting operations.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to FIG.

FIG. 1 is a block diagram showing an embodiment of a control parameter setting device for a building management system according to the present invention.

In FIG. 1, the distributed building management system includes a central monitoring device 1. A plurality of distributed terminal devices 2a, 2b.

2c and building equipment 14a, 14b.

Taking the distributed terminal device 2a as an example, the distributed terminal device 12
The control unit 13 built in a has a control parameter storage unit 12.
The building equipment 14a, 14b is controlled to be turned on or off according to the contents. Typical control parameters are data on the main control time and off control time of the building equipment 14a, 14b.

The contents of the control parameters can be entered using the keyboard 3. built into the central monitoring device 1. A person using a man-machine device such as the CRT 15 performs setting operations, and the settings are finally stored in the control parameter storage unit 12 of the distributed terminal bag @2a.

The details of the setting operation are as follows: When a control parameter is keyed in using the keyboard 3, the setting operation permission unit 4 determines whether the key-in is valid or invalid, and displays a message indicating whether the control parameter is valid or invalid on the CRT 15 via the display unit 9. Let me know. If valid, the control parameter is stored in the setting operation storage unit 5, and if invalid, the control parameter is discarded.

The setting operation storage section 5 can store a plurality of control parameters, and the stored control parameters are displayed on the CRT 15 via the display section 9.

When the control parameters are stored in the setting operation storage section 5, they are sent by the transmission section 6 to the transmission section 11 of the distributed terminal device 2a via the transmission line 10, and are stored in the control parameter storage section 12. When stored in the control parameter 12, the corresponding building equipment +4a.

14b, and the response is sent to the response processing section 7 via the transmission section 11. The response processing section 7 instructs that the setting of the corresponding control parameter stored in the setting operation storage section 5 is completed, and erases the memory thereof. On the other hand, the monitoring timer 8 sets the timer when the control parameters are stored in the setting operation storage section 5, and instructs the setting operation storage section 5 to disable the setting unless the setting is completed for a predetermined period of time, and stores the control parameters. Delete. The display unit 9 indicates whether the setting of the control parameters stored in the setting operation storage unit 5 is completed or cannot be set.
is displayed on the CRT 15 via.

The condition under which the setting operation permission unit 4 determines whether key-in is valid or invalid is that the control parameter is stored in the setting operation storage unit 5. Therefore, since a plurality of control parameters are stored in the setting operation storage section 5, setting operations can be performed one after another, which has the effect of eliminating time delays in setting operations.

In short, the point of the present invention is that by providing the setting operation storage section 5 shown in FIG. 1, it is possible to determine whether the settings of the setting operation permission section 4 are valid or invalid without any time delay.

〔Effect of the invention〕

As explained above, according to the present invention, when the control parameters set by the central monitoring device are stored in the terminal device connected by the transmission line, since the central monitoring device is provided with the setting operation storage unit, the control parameters set by the central monitoring device can be stored in the terminal device connected by the transmission line. This has the effect of allowing highly responsive operations without being affected by time delays caused by transmission.
