DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a building remote monitoring apparatus, and more particularly to a building remote monitoring apparatus using a communication line.

[0002]

2. Description of the Related Art A conventional building remote monitoring apparatus is a public telephone line that connects a monitoring station provided in a service company such as a security company or an equipment maintenance company and a monitored station provided in a building having many equipment. In this case, the monitored station notifies the monitoring station of an abnormal signal such as a failure of equipment in the building, the occurrence of a fire, or the entry of a suspicious person. However, since there is no consideration of performing data communication by calling an arbitrary monitored station from the plurality of connected stations from the monitoring station, even if a plurality of monitored stations are connected, the plurality of monitored stations can be monitored. It was difficult to select a station, and the telephone line could not be used effectively.

For this reason, as described in Japanese Patent Publication No. 6-71291, a monitoring station has a means for transmitting a redial and a means for outputting a termination prohibition signal, and a plurality of monitored stations are connected in parallel to the monitoring station. A receiving means for performing data communication when each of the plurality of monitored stations receives an incoming signal output from the monitoring station in accordance with a predetermined incoming order according to the incoming time, The station, when the receiving means receives the incoming stop signal output from the monitoring station,
An incoming call stop timer that counts a predetermined time corresponding to the time required for data communication by the monitored station with a lower incoming order, and disconnects the upper monitored station from the monitoring station while the incoming stop timer is operating. There has been proposed a building remote monitoring apparatus that selects one monitored station from a plurality of monitored stations by including a line control unit.

[0004]

However, in the conventional building remote monitoring apparatus, when the arrival order of the monitored stations is different from the order assumed by the monitoring stations, or the monitored stations are added or removed. In such a case, the incoming order will be different from the original one, and there is a possibility that a connection error may occur, and there is no means to confirm that the connection has been made securely.
When investigating the current incoming order and connection status, a worker must go to the building where the monitored station is installed and check the connection of each monitored station and the setting of the incoming order. It took a lot of time and trouble to reflect on the bureau.

It is an object of the present invention to provide a building remote monitoring apparatus which can connect to a desired monitored station by a simple procedure.

[0006]

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing the configuration and connection status of a monitoring station and a monitored station of a building remote monitoring apparatus according to an embodiment of the present invention. A monitoring station 1 provided in a service company such as a security company or a facility maintenance company is connected to a plurality of monitored stations 31, 32, and 33 installed in a building 4 via a communication line 2 such as a public telephone line. The communication line 2 is connected to each of the monitored stations 31 to 33 in parallel. Specifically, the monitoring station 1 includes a communication unit 1A that dials the communication line 2 and transmits a connection signal.
An identification information reading unit 1B for instructing reading of the identification information stored in the connected monitored station after connection with any one of the monitored stations 31 to 33, and identification information storage for storing the identification information Unit 1E and identification information reading unit 1B
Information comparing unit 1 for comparing the identification information read by the above with the identification information stored in the identification information storage unit 1E
D and an incoming call stopping unit 1C that instructs the connected monitored station to stop the incoming call.

Each of the monitored stations 31-33 waits for a time according to the order of arrival after detecting the connection signal from the monitoring station 1, and then receives incoming calls 31A, 32A and 33A.
And identification information storage units 31B, 32B, and 33B for transmitting identification information given to each monitored station in advance in response to an identification information read instruction from the monitoring station 1; When the incoming stop timers 31C, 32C, and 33C for which the set incoming stop time is set, and the incoming stop timers 31C, 32C, and 33C are set, the countdown of the timer is performed and the receiving section is only operated until the timer becomes 0. There are incoming call stopping units 31D, 32D, and 33D that instruct 3A not to make incoming calls. Terminating sections 31A, 32A, 3 of the monitored stations 31 to 33
3A, a time limit from the detection of a connection signal from the monitoring station 1 to the actual arrival of a call is set in accordance with the order of arrival of the monitored stations 31 to 33. A time limit of 5 seconds is set for the monitored station 31, 10 seconds is set for the monitored station 32 of the second incoming order, and 15 seconds is set for the monitored station 33 of the third incoming order. Also, the identification information holding units 31B, 32B, 33B of the monitored stations 31 to 33 are provided.
Stores identification information set to be unique for each monitored station. For example, the monitored station 31 having the first incoming order has “11010001”, and the monitored station 32 having the second incoming order has , Identification information such as "11010002" is set for the monitored station 33 in the third incoming call order.

The identification information storage unit 1E of the monitoring station 1 has an identification information table shown in FIG. 3, which stores identification information for specifying the monitored stations 31 to 33 and connection information. A telephone number, an incoming call order, and the number of stations to be monitored connected to one line are recorded for each monitored station for dialing.

FIG. 2 is a flowchart showing a communication procedure in a case where an arbitrary monitored station is selected for communication. For example, when communicating with the monitored station 32 having the identification information “11010002”, first, the number of trials is set to 1 in step S1.
Then, in step S2, a process of transmitting a connection signal such as dialing to the communication line 2 is performed.
In step 3, a connection is made to the first monitored station. At this time, if the configuration of the monitored station is as shown in FIG.
The connection with the monitored station 31 having the highest incoming call order is established. When the connection process between the monitoring station 1 and the monitored station 31 is completed in this way, in step S4, the identification information reading unit 1
B instructs the monitored station 31 to read the identification information, and the monitored station 31 instructed to read the identification information reads the identification information “1101” held in the identification information holding unit 31B.
0001 "to the monitoring station 1. In step S5,
The identification information comparison unit 1D of the monitoring station 1 or the monitor checks whether the identification information read from the monitored station 31 matches the identification information of the monitored station 32. 11010002 ", the monitoring station 1 sends a termination stop signal to the monitored station 31 in accordance with an instruction from the termination stop instructing unit 1C or a supervisor. The incoming call stop time at this time needs to be set longer for a monitored station with a higher incoming rank, so the actual incoming call stop time is (number of connections−number of trials) × 60 in step S6.
(Seconds) is calculated, and in step S7, the incoming stop time calculated in step S6 is set in the incoming stop timer 3C of the monitored station 31 from the incoming stop instruction unit 1C, and the line connection with the monitored station 31 is set in step S8. Disconnect. Call stop timer 3
The monitored station 31 for which the incoming call suspension time is set to C does not receive a call from the monitoring station 1 until the set incoming call suspension time elapses.

Next, after disconnecting the line with the monitored station 31, the monitoring station 1 increments the number of trials by one in step S9, and determines in step S10 whether the number of trials does not exceed the total number of monitored stations. If the number of trials does not exceed the number of all monitored stations, the process returns to step S2, and transmits a connection signal again. At this time, the incoming call of the monitored station 31 having the highest incoming order has been stopped in step S7, and therefore the incoming section 3A of the monitored station 32 having the next highest incoming order receives the incoming call. Subsequent steps S3 and subsequent steps are performed in the same manner as described above, but in step S5, the identification information read from the identification information storage unit 3B of the monitored station 32 performs communication in the identification information storage unit 1E of the monitoring station 1. Since the identification information matches the identification information “11010002” of the monitored station to be monitored,
At 12, the monitoring station 1 determines that the connection with the target monitored station 32 has been completed. However, when the processing up to step S9 is performed and the number of trials of the number of connected stations is executed in step S10, the identification information of the target monitored station held by the identification information storage unit 1E of the monitoring station 1 is If the identification information read from the identification information storage units 3B of all the connected monitored stations 32 do not match, a connection error is determined in step S11. In this way, even if there are a plurality of monitored stations 31 to 33 connected in parallel, it is possible to reliably connect to any monitored station by the identification information.

Now, the order of arrival of the monitored stations 31 to 33 is different from the identification information table of the monitoring station 1, and
Assuming that the monitored station 31 and the monitored station 32 are in order, in the first connection, the monitored station 33 having the first incoming order arrives, and the monitored station 33 responds to the identification information read instruction from the monitoring station 1. The identification information “11020001” stored in the 33 identification information storage unit 3B is returned. The identification information comparison unit 1D or the monitor of the monitoring station 1 transmits the returned identification information “11020001” and the identification information “1101” of the identification information storage unit 1E of the monitored station 32 to be connected.
0002 ", the identification information comparison unit 1D or the monitor of the monitoring station 1 stops the incoming call to the monitored station 33 by the incoming call stop instructing unit 1C. The monitored station 31 of the order receives the call, and returns the identification information “11010001” stored in the identification information storage unit 3B in response to the identification information read instruction from the monitoring station 1. Since the identification information is different from the identification information “11010002” of the identification information storage unit 1E, the identification information comparison unit 1D or the monitor of the monitoring station 1 stops the incoming call to the monitored station 31 by the incoming call stop instruction unit 1C. , The monitored station 32 of the third incoming order arrives, and the identification information reading unit 1 of the monitoring station 1
In response to the identification information read instruction from B, the monitored station 32
The identification information “1101” stored in the identification information storage unit 3B of FIG.
0002 ", which matches the identification information" 11010002 "of the monitored station to be connected, so that the identification information comparison unit 1D of the monitoring station 1 determines that the connection has been completed.
In this way, even if the arrival order of the monitored stations 31 to 33 is different from the identification information table of the monitoring station 1, it is possible to connect to the target monitored station.

FIG. 4 is a flowchart for examining the configuration of the currently-monitored station and the order of arrival using the building remote monitoring apparatus shown in FIG. When it is desired to know the current number of connected monitored stations and the order of arrival, the number of connected stations is set to 0 in step S20, and the number of trials is set to 1 in step S21. Next, in step S22, a connection signal such as dialing is transmitted from the communication unit 1A, and connection is made with the monitored station that has received the call in step S23. If the monitored station has the above-described configuration, the receiving order is highest. The monitored station 33 is connected. If it is confirmed in step S24 that the connection processing is completed, the monitoring station 1 increases the number of connected stations by 1 in step S25, and in step S26, the monitoring station 1 uses the identification information reading unit 1B to monitor the currently connected monitored station. When the station 33 is instructed to read the identification information, the monitored station 33 sends the identification information held in the identification information holding unit 33B to the monitoring station 1. In step S27,
The monitoring station 1 stores the number of trials in the item of the order of arrival in the identification information table of the monitored station 33 having the read identification information,
In step S28, (number of connected devices−number of trials) × 60 (seconds)
In step S29, the incoming stop time calculated in step S28 is set in the incoming stop timer 3C of the monitored station 33 from the incoming stop instruction unit 1C, and the line connection with the monitored station 33 is set in step S30. Disconnect. Therefore, the monitored station 33 in which the incoming call stopping unit 3D is activated by the incoming call stop timer 3C does not receive a call from the monitoring station 1 until the set incoming call stop time elapses. Therefore, after disconnecting the line with the monitored station 33, the monitoring station 1 increases the number of trials by one in step S31, and in step S32, the number of trials is equal to the maximum number of connected stations or the step S22 is performed until there is no incoming monitored station. The operations from to S31 are repeated. Here, step S22 is performed in the order of the monitored station 31 and the monitored station 32.
The operation from to is performed repeatedly.
Since the number of stations connected to the communication line is known when there are no incoming monitored stations, the monitored station from which the identification information could be read out in step S34 if it has been received at least once in step S33. Is recorded in the item of the number of connected units in the identification information table of the monitored station from which the identification information can be read.

By performing the above-described procedure, the number of monitored stations connected to the current monitoring station 1 and the order of arrival can be checked, and the identification information table shown in FIG. 5 is obtained. At this time, if the identification information read from the monitored station does not exist in the identification information storage unit 1E of the monitoring station 1, it is considered that the monitored station is newly added, and the identification information is stored in the identification information storage unit 1E. Register and make it a monitored station. In addition, although it exists in the identification information table on hand,
The monitored station that has not received a call is deleted from the identification information storage unit 1E and the identification information table as having been removed. Thus, the identification information storage unit 1 of the monitoring station 1
E and the identification information table reflect the current connection configuration of the monitored station, even if the order of arrival of each monitored station connected to the communication line is changed or the monitored station is newly removed. It is possible to obtain the identification information and the order of arrival of the monitored stations currently connected to the communication line.
