[Industrial application fields]
When a crime prevention / disaster prevention sensor installed in a security facility detects an abnormality, the alarm device in the facility transmits a warning to a remote monitoring center via a telephone line. The present invention relates to an alarm device that enables communication with a center.
[0002]
[Prior art]
Security officers who have been sent to check for abnormalities when alarms are transmitted, technicians who repair and inspect the sensors and alarm devices mentioned above, and employees of the security guards, etc., are responsible for making inquiries and reports. I often make phone calls with the observer. The telephone set used here is a security guard, and is usually used in an office or the like.
[Problems to be solved by the invention]
When making various inquiries, it is common to refer to drawings showing the operation status of various sensors, various setting information of the apparatus, and the installation locations of various sensors displayed on the display unit of the alarm device. And was forced to reciprocate between the alarm device. In particular, when security guards are checking alarm devices, they often make inquiries while doing some work by spreading the drawings, so both hands are blocked and there is inconvenience in talking with the handset.
[0003]
Further, when a security guard employee or the like makes an inquiry, he / she contacts after checking the telephone number of the monitoring center.
[0004]
Furthermore, when an alarm is received, in order to confirm whether there is an intruder or a fire has occurred, it is sufficient to listen to the guardian's voice for noise or abnormal sounds, but this is not possible at present. In addition, it is impossible to confirm whether or not someone is in the security guard that is not in the alert mode even at a predetermined time, or to intimidate the intruder loudly when receiving the alert.
[0005]
Further, when a security guard uses a security guard's telephone, a call charge is charged to the security guard regardless of the telephone call due to the security company's circumstances, and the guard pays an unjust expense.
[0006]
The present invention has been made in view of the above problems, and uses the telephone line of the alarm device between the security guard where the alarm device is installed and the monitoring center where the alarm device is installed and monitored as necessary. The purpose is to improve work efficiency by making calls. Another object of the present invention is to charge a call charge appropriately according to the usage status of the call device.

It is possible to make a telephone call.
[0010]
[Action]
According to the present invention, a so-called hands-free call is possible in which a call can be made with a monitor at a monitoring center without having a handset by operating a call operation means provided in the alarm device. In addition, when the security mode is the security release mode, it is set to the normal telephone number of the monitoring center so that the call fee is charged to the security guard, and in the security mode or the patrol mode, the security fee is charged to the security company. By selecting a phone number for a toll-free service, it is possible to prevent the security guard from paying undue expenses.
[0011]
【Example】
FIG. 1 shows a block diagram of an embodiment of the alarm device of the present invention.
[0012]
A hands-free control unit 1 controls the sound output of the speaker 2 in accordance with the sound input of the microphone 3 so that the user can talk without having to hold the hand like a handset of a normal telephone.
[0013]
Reference numeral 4 denotes a communication unit which performs a call with the monitoring center and transmission / reception of security information. 41 is a communication control unit that controls the entire communication unit, 42 is an automatic dial unit, 43 is an input / output unit that smoothly inputs and outputs voice signals and security information via a telephone line, 44 and 45 are telephone number storage units, In the toll-free telephone number storage unit, one of the telephone numbers is selected in accordance with a security mode to be described later and controlled so as to be communicable. Reference numeral 46 denotes an automatic receiving unit that automatically receives a call when the monitoring center 10 is called, 47 denotes a no-ringing call signal detecting unit that detects a no-ringing call signal, and 5 denotes a call operation unit including operation buttons and the like. Operate when making a call.
[0014]
6 is a security information processing unit for identifying a security mode by the operation of the security switching unit 7, transmitting a corresponding security mode signal to the communication control unit 41, and abnormal signals from various sensors not shown in the security mode. Is transmitted to the monitoring center 10 via the communication control unit 41, the automatic dial unit 42, the input / output unit 43, and the telephone line.
[0015]
Reference numeral 7 denotes a security switching unit which switches to any one of the security release mode, the security mode, and the patrol mode.
[0016]
Next, the operation of this embodiment will be described according to each security mode.
[1. When in security release mode]
When the security switching unit 7 is operated to “security release”, the security information processing unit 6 enters the security release mode and outputs a security release mode signal to the communication control unit 41. Thereafter, when a guarded employee or the like makes any inquiry to the monitoring center 10, the call operation unit 5 is operated. Then, the communication control unit 41 activates the automatic dial unit 42 to call the monitoring center 10. When the security release mode is set, the communication control unit 41 reads the normal telephone number from the telephone number storage unit 45 and operates the automatic dial unit 42 accordingly, so that the telephone charge is charged 3 to the security destination. . Then, the telephone line with the monitoring center 10 is captured, and a call can be made. The hands-free control unit 1 can make a call with a built-in microphone and speaker without having a normal telephone receiver. In the monitoring center 10, this hands-free function is not necessarily required, and any calling means such as a normal handset or a headset may be used.
[0017]
By the way, when the call is ended, the call operation unit 5 is operated again to open the DC loop of the telephone line. As another method, the call operation unit 5 may not be operated again, and the DC loop on the alarm device side may be automatically opened after detecting that the monitoring center 10 has disconnected the telephone.
[2. When in alert mode or patrol mode]
When the guard switching unit 7 is operated as “warning” or “patrolling” by the guard for inspection and the guard or the like reports various inquiries and inspection results to the monitoring center 10, a call is made in the same manner as described above. However, since the security guard calls in any mode, the communication control unit 41 operates the automatic dial unit 42 with the number from the toll-free telephone number storage unit 45 so that the monitoring center 10 is charged.
[3. When listening to abnormal sounds at the security center at the monitoring center]
When you want to check if there is no security guard employee remaining in the guard mode even after the specified time, receive an alarm, listen to the sound of an intruder or abnormal sound from a fire, etc. When threatening, the telephone number of the alarm device is dialed from the monitoring center 10 and a no-linking call signal is transmitted from a no-linking call signal transmission unit (not shown). When the no-ringing call signal detecting unit 47 of the alarm device detects the signal, the automatic incoming unit 46 automatically closes the DC loop of the line, and after the communication control unit receives the call command from the monitoring center 10, Make call available. Here, the reason why the no-ringing call signal is used is to identify whether the call is a normal call by the telephone or a call from the center 10 when the telephone line is also used as a normal call. . After that, it is possible to listen to the sound from the microphone, to ask the employee from the speaker, and to intimidate the intruder.
[0018]
As mentioned above, sound can be heard even in the security release mode. However, since there is a risk of violating the privacy of the security guard, calls from the surveillance center will be performed when the security equipment at the security guard is in the warning or patrol mode. It is good only as well.
[0019]
【The invention's effect】
According to the configuration of the present invention, it is possible to make a call between the guard and the monitoring center by using the telephone line used by the alarm device, and quickly and reliably by a simple operation of the call operation unit. Talk to the monitoring center while referring to the alarm device display.
[0020]
The hands-free function allows you to talk while working without having a handset.
[0021]
Moreover, the situation of the security guard can be captured by voice from the monitoring center as necessary.
[0022]
Furthermore, in the case of the security release mode, it is possible to legitimately and clarify the payee due to the reason for the cost by switching the telephone number so that the security center is charged with a call charge in the watch or patrol mode. .
