Description

[Detailed Description of the Invention] When an abnormal signal is reported from a building to two or more service companies, the same number of operation checks are performed with the service companies according to changes in the contents of the abnormal signal and monitoring contents. The present invention relates to a building remote monitoring system that lowers the occupancy rate of communication lines and reduces line charges.

Traditionally, systems have been adopted in small and medium-sized buildings that use general subscriber telephone lines to report abnormal signals such as malfunctions in building equipment, fires, and burglar intrusions to remote maintenance and security service companies. , this system can eliminate the need for building managers and is effective in saving labor.

However, if a failure occurs in the intrusion monitoring or fire monitoring parts, the monitoring will be disabled and the building will be left defenseless, so the operation of the equipment is checked between the building and the service company.

However, depending on the content of the monitoring, it may be necessary to separately report the signal to the security company and the maintenance company, but even in that case, the operation is checked by both companies at the same time, so the telephone charges will be reduced. There was a problem that caused the cost to increase.

This invention was made in consideration of the above points. For example, the frequency of checking the operation of the device is changed between the security company and the maintenance company, and the operation check for the maintenance company that does not require an emergency is performed with low bottle repulsion. The system lowers telephone charges by checking the operation of security companies in urgent cases. The present invention will be explained below with reference to the drawings.

Next, the operation of the embodiment shown in FIG. 1 will be explained.

Operation check for the security company faJlo Operation check at minute intervals When the crime prevention start switch 2 is turned on, the flip-flop 1, which is a memory, is set and the crime prevention monitoring signal i is output.

This crime prevention monitoring signal i is applied to the AND gate 8. On the other hand, the hexadecimal counter γ outputs an H" output at 10 minute intervals. Therefore, this is AND gate 8. Off gate 9.
10] Set ship 7p Tsuzu 17. Further, the operation check command signal f2 that has passed through the off gate 9 is applied to the AND gate 14 through the off gate 12.

Of the other two people in And Gate 14, Off Gate 18
Since the signal from 1 is L'', it is inverted and becomes H'', so when the signal R is added, an output is output from the AND gate 14 and the 17 lithop hoop 16 is sent. The automatic dialing device 2o is activated by the output from the frig-from 160, and automatically dials the security company 34. When the automatic dialing is completed, the Atayal completion signal j' is the OR gate 25.
The building number transmitting device 26 is activated to transmit the building number.

On the other hand, since the output terminal becomes "H" at the same time as the 7 limb 70 knob 16 is set, its output passes through the off gate 18 and is applied to the AND gate 14, closing the 7 AND gate 14. At the same time, the output of the flip-flop 16 is also applied to the gate 290T terminal, data such as an operation confirmation signal from the flip-flop 1T is sent, and finally a data output completion signal 1 is sent.

The security company 34 assumes that the device is operating normally while this signal is being sent. If this signal is not received, it assumes that there is an abnormality and dispatches the device to repair it. Also, the data output completion signal l causes the security company to The 7p knob 16°11 is reset.

Repeat the above sequence at 10 minute intervals. Thereafter, by turning on the crime prevention end switch 3 and resetting the flip-flop 1, the 10-minute interval operation ends.

(b) Operation check at 2 hour intervals The output B of the counter 6 becomes 'H' at 2 hour intervals.

This causes 7 lipfrog 11 to be sent.

Further, since the operation check command signal f2 is output from the OR gate 9, the signal is sent to the security company 34 and the operation check is performed in exactly the same way as the operation check at 10 minute intervals described in (a).

(Bl Operation check for maintenance company (a) Operation check at 2 hour intervals The output A of the counter 6 becomes 'H' at 2 hour intervals, the operation check command signal f1 is output, and this is off) 1
．． 1, passes through the AND gate 13 and sends the flip-flop 15 to cents. As a result, the automatic dialing device 19
is activated and automatically informs the maintenance company 30. after that,
As a result of transmitting the building number from the building number transmitting device 26 and opening the gate 28, data such as each signal a-'-e, an operation confirmation signal from the flip-flop 1γ, and a data output completion signal l are transmitted. Similar to the operation check by the security company 34 in case (A) above, the maintenance company 30 determines that there is no abnormality in the device if the data output completion signal l is sent at two hour intervals.

(b) Sequence when failure occurs - As an example, a case where the elevator fails will be explained.

When a failure occurs in the elevator, the elevator failure signal e
is generated, which passes through the off gate 11 and is added to the AND gate 13. As a result, an output is output from the AND gate 13, the flip-flop 15 is set, and the automatic dialing device 19 automatically dials the maintenance company 30 and sends the building number. Next, since the gate 28 is open, the elevator failure signal e is transmitted to the data transmitting device 27.
Send from. The maintenance company 30 learns of the failure of the elevator as described above, and dispatches to the building to repair the elevator. Incidentally, when the data output completion signal 1 is output, the flip-flops 15 and 17 are set.

In addition, the failure data may be output to both the maintenance company 30 and the equipment company 34, and each company may select only the necessary data (the time interval for operation confirmation may be changed arbitrarily). In addition, you may want to increase the frequency of operation checks in buildings where there are many breakdowns, fires, and burglars.Furthermore, if the automatic dialer does not connect, try dialing another phone from that company again. And,
The signal form of the data may be simply parallel-to-serial converted, decoded, or other encoded form. Furthermore, the transmitted signals may be sent and received between the maintenance company 30 and the security company 340 to exchange data, and the operation confirmation signal includes the time interval periodic signal of the next operation confirmation signal. It may be possible to make it easier to confirm. Furthermore, if there is an important signal other than crime prevention, the frequency of operation confirmation can be changed in each summer.

As explained in detail above, the present invention is capable of reporting an abnormal signal from a hill to two or more service companies (for example, a maintenance company and a security company), depending on the contents of the abnormal signal, or when the situation of monitoring contents changes. As a result, the number of active magazines with each service company is changed, which has the advantage that unnecessary communication can be omitted and line charges can be reduced.
