Description

[Detailed Description of the Invention] When an abnormal signal is reported from a building to two or more service companies, the number of operation checks with the service company is determined according to changes in the contents of the abnormal signal and monitoring contents. This relates to a building remote monitoring system that reduces the occupancy rate of communication circuits and reduces line charges.

Traditionally, systems have been adopted in small and medium-sized buildings that use regular subscriber telephone lines to report abnormal signals such as the occurrence of equipment in the building, the occurrence of a fire, the occurrence of thieves invading, etc., to a service company that performs maintenance and security at a distance. This allows the building manager to be absent, resulting in a labor-saving effect.

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

However, depending on the content of the monitoring, it may be necessary to report the signal to the security company and the maintenance company separately, but even in that case, the operation is checked with both companies at the same frequency, which reduces the cost of telephone charges. There was a problem where the value increased.

This invention was made in consideration of the above points, and 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 less frequently. This system lowers telephone charges by frequently checking the operation of security companies in urgent situations. 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.

(A) Operation check for security company (a) Operation check at 10 minute intervals When crime prevention start switch 2 is turned on, flip-flop 1, which is a memory, is set and 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 7 outputs "H" at 10 minute intervals. Therefore, this sets flip-flop 17 through AND gate 8 and OR gates 9 and 10. In addition, the operation check command signal f ₂ passing through the OR gate 9 is transmitted to the OR gate 1.
2 and is applied to the AND gate 14. Of the other two inputs to the AND gate 14, the one from the OR gate 18 is "L", so it is inverted and becomes "H", so when signal D is added, an output is output from the AND gate 14,
The automatic dialing device 20 is activated by the output of the flip-flop 16, and automatically dials the security company 34. When the automatic dialing is completed, a dialing completion signal j' passes through the OR gate 25 and activates the building number transmitting device 26 to transmit the building number.

On the other hand, since the output terminal of the flip-flop 16 becomes "H" at the same time as it is set, its output passes through the OR gate 18 and the AND gate 1.
4 and close the AND gate 14. At the same time, the output of the flip-flop 16 is applied to the T terminal of the gate 29, so the gate opens, and the fire occurrence signal g, the intrusion occurrence signal h, the security monitoring signal i, and the operation confirmation signal from the flip-flop 17 are transmitted. etc. are sent, and finally a data output completion signal l is sent.

The security company 34 considers that the device is operating normally while this signal is being sent. If this signal is not received, it is assumed that there is an abnormality and dispatched to repair the equipment. Furthermore, the flip-flops 16 and 17 are reset by the data output completion signal 1.

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 operation check ends.

(b) Operation check at 2 hour intervals Output B of counter 6 is “H” at 2 hour intervals
become. As a result, the flip-flop 17 is set, and the operation check command signal _f2 is output from the OR gate 9, so the rest is as described in (a).
A 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.

(B) Operation check to maintenance company (a) Operation check at 2 hour intervals Output A of counter 6 goes “H” at 2 hour intervals
Then, an operation check command signal _f1 is output, which passes through the OR gate 11 and the AND gate 13 to set the flip-flop 15. This activates the automatic dialing device 19 and automatically dials the maintenance company 30. After that, the building number is transmitted from the building number transmitting device 26,
Furthermore, as a result of opening the gate 28, each signal a to e
etc., the operation confirmation signal from the flip-flop 17, and the data output completion signal l.
will be sent. 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 a failure occurs As an example, we will explain the case where an elevator malfunctions.

When a failure occurs in the elevator, an elevator failure signal e is generated, which is sent to OR gate 1.
1 and is added to 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 from the data transmitting device 27. The maintenance company 30 learns from the above that the elevator has broken down, and dispatches to the building to repair the elevator. Note that when the data output completion signal l is output, the flip-flop 1
5 and 17 are reset.

In the above embodiment, the portion between the flip-flop 15 and the OR gate 11 and
The 72,000-decimal counter 6 and the like correspond to means for activating the automatic dialing device 19 at predetermined time intervals, and similarly, the flip-flop 1 and flip-flop 7 and the like correspond to means for starting the automatic dialing device 20 at predetermined time intervals. The failure data may be output to both the maintenance company 30 and the security company 34, and each company may select only the necessary data, and the time interval of operation confirmation may be changed arbitrarily. Furthermore, the frequency of operation checks may be increased in buildings where failures occur frequently, or buildings where fires or burglars frequently break in. Furthermore, if the automatic dialing does not connect, try dialing another phone from that company again, or simply convert the data signal form from parallel to serial, or convert it to decoded or other encoded form. good. Furthermore, the transmitted signals may be sent and received between the maintenance company 30 and the security company 34 to exchange data, and the operation confirmation signal may include the time interval periodic signal of the next operation confirmation signal. It may be possible to make it easier to check the operation. Furthermore, if there is an important signal other than crime prevention, the frequency of operation confirmation can be changed each time.

As explained in detail above, the present invention provides an automatic dialing system for reporting an abnormal signal from a building to two or more service companies (for example, a maintenance company and a security company) using one device. Since it is possible to automatically select and report information at the same time and check the operation at the same time, unnecessary communication can be omitted and line charges can be reduced. Moreover, even if the maintenance company's dial number changes, it is not possible to periodically report to the maintenance company, so it is possible to immediately check for maladjustment of the automatic dialing device.
