Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility management system and, more particularly, to a method of sending an external operation instruction to a monitoring control device for monitoring and controlling facilities installed in a building or the like.

[0002]

2. Description of the Related Art Conventionally, as a facility management system, there is a system for centrally controlling the vertical movement of a blind installed in a window of a building and a slat angle and automatically controlling the same. In this system, a blind controller of each blind is automatically controlled by a floor controller connected by a serial line by periodically collecting status and scheduling. Each blind can be controlled by a resident operating an area switch panel.

In the above facility management system, the state of each blind periodically collected by each blind controller is sent to the floor controller in response to a simultaneous polling signal from the floor controller operating as a center device. The floor controller centrally manages the state of each blind based on information from each blind controller.

As an information collection method using the above-mentioned polling signal, there is a method disclosed in Japanese Patent Application Laid-Open No. 56-65300. That is, in the information collection method described in this publication, a wireless transceiver is provided in a terminal such as a traffic signal, and simultaneous polling from a failure information collection center and transmission of traffic state information from a target terminal in the area accompanying this are performed. And a random notification period in which fault information can be transmitted to the fault information collection center immediately when a fault occurs on the terminal side.

In the above information collection method, when the terminal receives the simultaneous polling transmitted from the failure information collection center, the terminals within the area included in the area number assigned to the simultaneous polling are individually determined. Traffic condition information is sequentially transmitted to the obstacle information collection center at time intervals. From the end of the response from the terminal to the simultaneous polling from the failure information collection center to the start time of the next simultaneous polling, a random alert period is set, and the terminal can immediately transmit the failure information.

[0006]

In the conventional information collection method described above, traffic condition information from terminals is sequentially collected by simultaneous polling, and failure information from terminals is received as needed during a random alert period. .

When this method is used in the above equipment management system, the blind state is periodically collected from the blind controller by simultaneous polling, and operation information of the area switch panel is transmitted to the blind controller during a random alert period. Becomes In this case, the operability of the area switch panel can be secured by shortening the simultaneous polling cycle or lengthening the random alert period, but if the resident operates the area switch panel during the execution of the simultaneous polling, The transmission of the state information from the blind controller to the floor controller and the transmission of the operation information from the area switch panel to the blind controller may overlap, and the operation information from the area switch panel may be discarded.

In addition, when a plurality of area switch panels are simultaneously operated during the above-mentioned random alerting period and operation information is transmitted from each of the plurality of area switch panels to the blind controller at the same timing, the operation from the area switch panel is performed. There is a risk of misrecognition or destruction of information.

Accordingly, an object of the present invention is to provide an equipment management system which can solve the above-mentioned problems, can prevent congestion of operation information for equipment, and can ensure the reliability of the operation information. It is in.

[0010]

An equipment management system according to the present invention includes a center device for centrally managing the status of various types of equipment, each of which controls the equipment and sends the status of the equipment to the center device as monitoring information. Including a plurality of monitoring and control devices, and a plurality of terminal devices each transmitting operation information from the outside to the equipment to the plurality of monitoring and control devices,
A facility management system configured to sequentially send the monitoring information from each of the plurality of monitoring control devices to the center device in response to a simultaneous polling signal from the center device, wherein the monitoring information is transmitted to each of the plurality of terminal devices. The center device includes means for outputting a simultaneous transmission right release polling signal for permitting transmission of the operation information to each of the plurality of monitoring control devices.

[0011] In another equipment management system according to the present invention, in addition to the above configuration, the transmitting means for transmitting the operation information to the plurality of monitoring and control devices in response to the simultaneous transmission right release polling signal is provided. It is provided for each terminal device.

In another equipment management system according to the present invention, in addition to the above configuration, means for holding at least operation information from outside until at least the simultaneous transmission right release polling signal is input is provided in each of the plurality of terminal devices. I have it.

That is, even when the simultaneous polling release polling transmission is added to the floor controller and the simultaneous polling period is shortened in order to enhance the operability, the area switch panel receives the simultaneous transmission right release polling and thus receives the transmission timing. , The reliability can be secured as compared with the method of measuring and obtaining the synchronization timing.

After transmitting the operation information from the area switch panel in response to the reception of the simultaneous transmission right release polling,
A re-confirmation transmission function for transmitting the same operation information again after a predetermined time individually determined in synchronization with the reception of the simultaneous transmission right release polling is added. In this case, since the blind controller in the area can determine that the operation is normal when the operation information of the area switch panel is continuously received, the state information of the blind controller and the area switch panel are compared with the method without reconfirmation transmission. Of the operation information from each of the plurality of area switch panels and the operation information received by the blind controller can be prevented, and the reliability of the operation information can be secured. be able to.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an equipment management system according to one embodiment of the present invention. In the figure, in the equipment management system, the equipment management device 11

This equipment management system is a system for centrally managing a plurality of equipment (not shown). The equipment management device 11 periodically collects the equipment status from the monitoring control devices 21 to 2n. The monitoring control devices 21 to 2n monitor the status of the connected equipment and control the equipment based on a control message from the serial line 100. The operation terminal devices 31 to 3m use the serial line 100 as an operation control message for the operation by the operator.
To operate the equipment under the control of the monitoring and control devices 21 to 2n. The operation terminal devices 31 to 3m hold the operation control message at least until an operator operates the operation control message and receives a transmission permission signal (broadcast transmission right release polling) from the facility management device 11.

In the above-described blind management system, the floor controller corresponds to the equipment management device 11, the blind controller corresponds to the monitoring control devices 21 to 2n, and the area switch panel corresponds to the operation terminal devices 31 to 3m.

FIG. 2 is a block diagram showing the configuration of the monitoring control device 21 of FIG. In the figure, a supervisory control device 21 includes a line control unit 21a that controls data transfer between devices constituting a system, and a monitoring unit 21 that monitors the state of equipment.
b, and a control unit 21c that outputs a control signal corresponding to a control message from the serial line 100 to the equipment.
Although not shown, the other monitoring control devices 22 to 2n have the same configuration as the monitoring control device 21 described above.

FIG. 3 is a block diagram showing the configuration of the operation terminal device 31 of FIG. In the figure, an operation terminal device 31 includes a line control unit 31a that controls data transfer between the devices constituting the system, and an operation input unit 31b that inputs an operation by an operator and generates an operation control message. . Although not shown, the other operation terminal devices 32 to 3
m has the same configuration as the operation terminal device 31 described above.

FIG. 4 is a flowchart showing the operation of the monitoring control devices 21 to 2n in FIG. 1, and FIG. 5 is a flowchart showing the operation of the operation terminal devices 31 to 3m in FIG. FIG. 6 is a sequence chart showing a communication sequence between each device of the equipment management system according to one embodiment of the present invention, and FIG. 7 is a timing chart showing the timing of the communication sequence shown in FIG. The communication sequence of the equipment management system according to one embodiment of the present invention will be described with reference to FIGS.

In the equipment management system according to the embodiment of the present invention, the monitoring control devices 21 to 2n are provided for every x units (x is a positive integer).
, And simultaneous polling is performed for each block. That is, the facility management apparatus 11 uses the block No.
1, block No. 2, ..., Block No. b, ...
All polling is performed in the order of. In this case, block No.
1 is the monitoring control device 21 to 2x of the address # 1 to #x, and the block No. 2 is the monitoring control device 2 (x + 1) to 2 (2x) of the address # (x + 1) to # 2x, and the block No. b
Are composed of monitoring control devices 2 [x (b-1) +1] to 2 (bx) at addresses # [x (b-1) +1] to #bx, respectively.

The equipment management apparatus 11 first receives the block No. 1
When the simultaneous polling is performed, the monitoring control devices 21 to 2x transmit a response message, that is, a monitoring status message indicating the state of the equipment, after a delay time D set in advance corresponding to the own address (step S1, FIG. 4). S6, S7) (see FIG. 6).

The equipment management device 11 has a block No. After the simultaneous polling of the operation terminals 1, the operation terminal devices 31 to 3
m, a simultaneous transmission right release polling for permitting transmission of the operation control message to the monitoring control devices 21 to 2n is performed. In this case, since each of the operation terminal devices 31 to 3m holds the operation control message if the operation is performed by the operator, it transmits the operation control message without delay in synchronization with the simultaneous transmission right release polling (FIG. 5 steps S11, S1
4 to S16) (see FIG. 6).

Thereafter, the operation terminal devices 31 to 3m transmit the same operation control message again (hereinafter referred to as reconfirmation transmission) after the delay time D1 to Dm set in advance corresponding to the own address (FIG. 5). Steps S17 and S18) (see FIG. 6).

Here, the delay time at the time of reconfirmation transmission will be described with reference to FIG. In FIG. 7, t0 indicates a transmission time of a transmission permission message (broadcast transmission right release polling signal) from the facility management apparatus 11 to the operation terminal apparatuses 31 to 3m, and t1 indicates an operation control of the operation terminal apparatuses 31 to 3m. The transmission time of the message is indicated, t2 is a time margin between the messages, and t3 is a delay time inherent to the operation terminal device.

D1 = (t1 + t2) + t3 × 0 D2 = (t1 + t2) + t3 × 1 D3 = (t1 + t2) + t3 × 2 D4 = (t1 + t2) + t3 × 0 t1 + t2) + t3 × 3 Dm = (t1 + t2) + t3 × (m−1) Therefore, address #y including address # 1
The delay time Dy of (y = 1 to m) is represented by Dy = (t1 + t2) + t3 × (y-1).

When simultaneous polling of the blocks is received during the transmission of the operation control message in the operation terminal devices 31 to 3m (steps S11 and S12 in FIG. 5), the operation terminal devices 31 to 3m interrupt the transmission of the operation control message. (Step S13 in FIG. 5). Also, the monitoring control devices 21 to 21
2n, upon receiving the simultaneous transmission right release polling during transmission of the monitoring state message (steps S1 and S2 in FIG. 4), interrupts transmission of the monitoring state message (step S3 in FIG. 4). Further, when the monitoring control devices 21 to 2n receive the control message including the operation control message (Step S4 in FIG. 4), they receive the control message (Step S5 in FIG. 4).

The equipment management device 11 includes operation terminal devices 31 to 3
When the broadcast right release polling for m is completed,
That is, when the time Tm at which the operation terminal device 3m of the maximum address (#m) among the operation terminal devices 31 to 3m finishes transmitting the operation control message has elapsed, the next block No. Block polling for block 2 is performed. This is performed in the same manner as the simultaneous polling for 1. This block No. 2 is completed, that is, block N
o. Monitor control device 2 of the maximum address (# 2x)
When the time Tx at which (2x) ends transmission of the monitoring state message has elapsed, the facility management apparatus 11 performs simultaneous transmission right release polling on the operation terminal apparatuses 31 to 3m in the same manner as described above (see FIG. 6).

The operation terminal devices 31 to 3m, which have received the simultaneous transmission right release polling from the facility management device 11, hold the operation control message by the operation of the operator and transmit the operation message. Therefore, even when the number of monitoring control devices is large, the efficiency of state collection of the monitoring control devices 21 to 2n can be improved while ensuring the operation response of the operation terminal devices 31 to 3m.

FIG. 8 is a sequence chart showing the operation when the simultaneous transmission right release polling is not used according to one embodiment of the present invention. FIG. 9 is the sequence chart when the simultaneous transmission right release polling according to one embodiment of the present invention is used. 6 is a sequence chart showing the operation of FIG. The simultaneous transmission right release polling according to an embodiment of the present invention will be described with reference to FIGS.

When the simultaneous transmission right release polling is not used, the operation terminal devices 31 to 3m measure the transmission timing of the operation control message in synchronization with the reception of the simultaneous polling.
The transmission of the operation control message from the operation terminal devices 31 to 3m is congested with the transmission of the monitoring state message from the monitoring control devices 21 to 2n when the measured value of the transmission timing is less than Tmin, and the measured value of the transmission timing is Tmax. If it exceeds, transmission of simultaneous polling from the equipment management apparatus 11 will cause congestion.

Therefore, for example, if operation a is performed after the operation terminal devices 31 to 3m start measuring the transmission timing, the transmission of the operation control message b corresponding to the operation a is performed when the transmission timing measurement value is Tmin. Must be done before crossing. If the operation control message b is transmitted at a timing other than this timing, the above congestion will be caused (see FIG. 8).

On the other hand, when the simultaneous transmission right release polling is used, the operation terminal devices 31 to 3m can immediately transmit the operation control message in synchronization with the reception of the simultaneous transmission right release polling. That is, the occurrence of the congestion as described above does not occur.

In this case, even if the operation a is performed after the facility management apparatus 11 transmits the simultaneous polling, the simultaneous transmission right prohibition period is not received since the operation terminal apparatuses 31 to 3m do not receive the simultaneous transmission right release polling. The transmission of the operation control message c corresponding to the operation a is prohibited.
Therefore, the operation terminal devices 31 to 3m hold the operation control message c until the simultaneous transmission right release polling is received.

When the operation terminal devices 31 to 3m receive the simultaneous transmission right release polling, the simultaneous transmission right release period starts. Therefore, the transmission of the operation control message c held until then is synchronized with the reception of the simultaneous transmission right release polling. (Fig. 9
reference).

FIG. 10 is a sequence chart showing an operation when reconfirmation transmission is not performed according to one embodiment of the present invention, and FIG. 11 is a sequence chart showing an operation when reconfirmation transmission is performed according to one embodiment of the present invention. It is a chart. The reconfirmation transmission according to one embodiment of the present invention will be described with reference to FIGS.

When the reconfirmation transmission is not performed, for example, after the simultaneous polling is transmitted from the facility management apparatus 11, the measurement value of the transmission timing at the operation terminal apparatuses 31 to 3m becomes Tmi.
before the operation terminal device 31 or 32 is operated,
When e is performed, the operation terminal devices 31 and 32 transmit operation control messages f and g respectively corresponding to the operations d and e when the measured value of the transmission timing exceeds Tmin. In this case, since the operation terminal devices 31 and 32 transmit the operation control messages f and g based on the measurement values of the transmission timing, the transmission of the operation control messages f and g is congested (see FIG. 10).

On the other hand, when the reconfirmation transmission is performed, as described above, the operation d, e
Is performed, the operation terminal devices 31 and 32 transmit operation control messages f and g corresponding to the operations d and e, respectively, in synchronization with the reception of the simultaneous transmission right release polling. Operation terminal device 3
After the transmission of the operation control messages f and g, the operation control messages h and i, which are the same as the operation control messages f and g, respectively, are transmitted to the delay times D1 and D2 set in advance in accordance with the respective addresses # 1 and # 2. D
2 is transmitted (see FIG. 11).

In this case, the monitoring control devices 21 to 2n judge that an abnormality has occurred unless the same operation control messages f and h or operation control messages g and i are continuously received from the operation terminal devices 31 and 32, respectively. Therefore, even if the transmission of the operation control messages f and g from the operation terminal devices 31 and 32 becomes congested after receiving the simultaneous transmission right release polling, the operation control messages h and i having the same contents as the operation control messages f and g are transmitted. Since the transmissions are performed at different times, it is possible to avoid an adverse effect due to the congestion of the transmission of the operation control messages f and g.

As described above, the simultaneous polling from the equipment management apparatus 11 to the monitoring control apparatuses 21 to 2n to permit transmission of the monitoring state message and the simultaneous transmission right release from the operation terminal apparatuses 31 to 3m to permit the transmission of the operation control message. By transmitting the polling, each of the operation terminal devices 31 to 3m can acquire the synchronization of the transmission timing. Therefore, reliability is ensured as compared with the method of measuring the synchronization timing for transmitting the operation control message. be able to.

After the operation terminal devices 31 to 3m transmit the operation control message in response to the reception of the simultaneous transmission right release polling, the same operation control message is set in advance corresponding to the addresses # 1 to #m. By transmitting again after the delay times D1 to Dm elapse, the congestion between the transmission of the monitoring state message from the monitoring control devices 21 to 2n and the transmission of the operation control message from the operation terminal devices 31 to 3m and the operation terminal device 31 to 31m. 3m
Can prevent congestion between transmissions of operation control messages from the network, and can prevent erroneous recognition of operation control messages received by the monitoring control devices 21 to 2n, thereby ensuring reliability of the operation control messages. be able to.

[0042]

As described above, according to the equipment management system of the present invention, simultaneous polling transmission for permitting transmission of monitoring information to the supervisory control device and operation of the terminal device to the supervisory control device are performed. By providing the center device with a function of performing simultaneous transmission right release polling that permits transmission of information, congestion of transmission of operation information to equipment can be prevented, and reliability of the operation information can be ensured. There is an effect that can be.

According to another equipment management system of the present invention, after transmitting operation information in response to the reception of the simultaneous transmission right release polling, the same operation information is transmitted for the delay time set individually for each terminal device. By transmitting the information again after the elapse, it is possible to prevent the operation information from being congested with respect to the equipment, and to ensure the reliability of the operation information.
