Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a building management system that centrally monitors building equipment.

[Background of the invention]

Figure 1 shows a conventional distributed building management system.

The remote station 5 (几S1 to R83) is connected to each field device 6 (a-c) 911, such as power receiving substation/private power generating device,
They are installed at each site corresponding to various power panels, air conditioners, water supply and drainage equipment, etc., and are connected to the central monitoring device 4 by a transmission line 7 such as a coaxial cable or an optical fiber. The central monitoring device 2 includes a central monitoring console 3,
A typewriter 4 is connected so that the operator 1 can monitor the operation of equipment at each site within the building using information output from the central monitoring console and the typewriter. The remote station has a built-in microcomputer that controls input/output with each field device, data transmission control with the central monitoring device, and Kogal! ! ! 1a gua
Performs gram processing, etc. This transmits the operating status of each field device to the central monitoring device through the transmission line, and the central monitoring device edits the data sent from each remote station and outputs it to the central monitoring console and typewriter. . Further, data input by an operator via the central monitoring console is transmitted to a remote station via a transmission line, and further output as control information to field equipment. This allows the air conditioning equipment on each floor, from the center to the center, to be activated or deactivated. The total number of input/output points that are monitored and controlled in this manner can be as high as 10,000 points in a medium-sized building, or as many as 10,000 points in a large-scale building.

Figure 3 shows the array of interface circuits between the remote station and the on-site power panel.

DO of the output circuit of the input/output control section of the remote station
When I is output, relay CX on the power panel operates and
If the on-site changeover switch is switched to the far side, the power supply relay 52 operates and maintains itself. Therefore, the output signal DOI from the remote station may be a pulse signal that operates for a certain period of time. Auxiliary relay 52X of closing relay 52
Since the contact is connected to the input circuit Di1, the remote station can receive the operating state of whether the power is turned on or not. In order to realize such an interface, it is necessary to add a relay for the 0 part on the power panel side in advance and configure a circuit for the 0 part. In addition, in the section 0 between the remote station and the power panel, each terminal will be connected via construction wiring.

In this way, when constructing a building management system, after the construction wiring of the central monitoring device, remote station, etc. and each field device is completed, power is turned on and an adjustment test is performed. This means checking the total number of connection points in the circuit described above one by one. That is, the central monitoring device outputs an output corresponding to f)01 of the output circuit in Fig. 3 via the remote station, confirms on the power panel that the closing relay 52 has operated, and further checks its operating state. Confirm that it is transmitted to the central monitoring device via the input circuit Di1.

If it does not work properly, there is a problem with the circuit at part ■ in Figure 3, or if there is a problem with the on-site wiring at part [F].
A malfunction in the relay circuit of O, a configuration error in the circuit of O, and furthermore,
Various conditions exist, such as when the remote/on-site switch in the 0 section is switched to the on-site side, and the operator in the central monitoring room and the on-site operator check this by phone or transceiver. This work is very inefficient and takes a lot of time if there are many input/output points. Further, when a problem occurs, there are some problems that require a great deal of time to investigate the cause.

[Purpose of the invention]

An object of the present invention is to provide a distributed pill management system that can efficiently complete adjustments in a short time during on-site adjustment tests.

[Summary of the invention]

The feature of the present invention is that by attaching a button-pull type operation panel to the remote station installed on the site,
Interface adjustment between field devices and remote stations and local control of the current four devices can be done only on the field side.
The reason is that each station can be executed independently.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIG.

The remote station usually has its overall control managed by an execution management section, and transmits and receives input/output data to and from field equipment to a central monitoring device. The array of interface circuits with field equipment is shown in FIG. The remote station receives input contacts on the field side, and outputs operation commands for output relays through processing. Processing of these input/output interfaces is performed by the input/output control unit 13, and the fetched data is stored in the data buffer unit. Generally, this process is performed cyclically by activation of the execution management section 9. On the other hand, the transmission control section 10 controls the transmission and reception of data with the central monitoring device. When a request is issued from the central monitoring device, the transmission control section 10 transmits the input data in the data buffer section 11 to the central monitoring device. The output data sent from the monitoring device is set in the data buffer section 11.

The set output data is outputted to the field equipment by the input/output control section 13.

Here, by providing an operation panel control section 12 and connecting a simple operation panel 8 to the outside, a data transmission section 10 is constructed to transmit input/output data of the same cage to and from the central monitoring device. A feature of the present invention is that it can be processed in 8.

That is, when the simple operation panel 8 is connected and the maintenance person keys in the data he/she wants to monitor from the operation panel, the operation panel control section 12 decodes the data and retrieves the corresponding data from the data buffer 7 and 11. and output it to the simple operation panel 8.

The same goes for output; when the data to be output is keyed in on the operation panel, it is set in the data buffer section 11. That is, the operation panel control section 12 performs the same processing as that performed by the transmission control section 10 on the data buffer section 11, but the following processing by the input/output control section 13, etc. It is exactly the same as the normal case. Therefore, input/output can be checked only on the field side, regardless of whether the transmission control unit, transmission line, or central monitoring device is normal or malfunctioning.

In addition, by incorporating the test program 14 into the simple operation panel 8 in advance, maintenance personnel can simply issue a start command to the simple operation panel 8, and the test data will be sequentially transmitted via the operation panel control section 12 according to the test program. Buffer section 11
is set to

For example, it is possible to output the output for each connected building equipment every few seconds, capture the input signal, and automatically check whether the corresponding unloaded signal is returned. .

〔Effect of the invention〕

According to the present invention, interface adjustment tests between field devices and remote stations can be performed only on the field side, regardless of the central monitoring equipment and transmission lines, so work can be performed at close distances, and the conventional central and field Compared to the work that is done while communicating with each other, it is more efficient to cut the grooves.

Brief explanation: Figure 1 is a block diagram of a remote station according to the present invention, Figure 2 is a block diagram of a conventional distributed pill management system, and Figure 3 is an interface circuit between the remote station and field equipment. It is a diagram.
