Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telecontrol device that monitors and controls indoor equipment and reports an abnormality via a telephone line.

[Conventional technology]

Conventionally, as this type of telecontrol device, for example, t
As described in "Development status and trends of bar telecontrol systems and their applications" (Japan Technology Information Center Educational Planning Department), the following five devices are shown.

FIG. 2 shows an outline of a system configuration using this type of telecontrol device. In the figure, (15) is the telecontrol device, terminal (1) is connected to the subscriber line connected to the exchange (17), and terminal (2) is the telephone (1).
8), the control output terminal (13) is connected to the control adapter (20) of the target device (21) such as an air conditioner, and the monitor input terminal (14) is connected to the security sensor (19) such as an emergency switch or fire sensor. It is connected to the.

Note that (16) is an external push-phone 7 type telephone. FIG. 6 shows the configuration of a conventional control device (15). The main control section (4) controls the line connection section (3) via the network control interface section (5), and connects the joining line connection terminal (1) to the control signal reception section (6) and the voice synthesized sound transmission section (7). )1 Incoming call detection section (8).

Connect to this telephone connection terminal (2). In addition, the main control unit (4
) drives the control output unit (11) to output a control signal for the target device (21) to the terminal (13), and also outputs the control signal for the target device (21) to the terminal (13).
The output No. 4g of the security sensor (19) applied to the security sensor (14) is read through the monitor input section (12).

The outline of the operation of the telecontrol device (15) is as follows. This will be explained using a seventh timing chart showing the operation of the conventional device, a flowchart in FIG. 3 common to the device according to the embodiment of the present invention, and a message table in FIG. 8.

When you set the disconnector of the line connection part (3) to the telecontrol side and set the teleconverter mode from the operation part when you go out, the main control part (4) prepares for automatic response [step (Fig. 3)]. 22) ].

When a call is made from the external telephone (16), the ringing signal is detected by the incoming call detection section (8), and the incoming call detection signal is input to the main control section (4). Then, the main control unit (4)
The line connection section (3) is controlled to close the line, and at the same time, the voice synthesized sound sending section (7) is controlled to send out an automatic response message Mt (FIG. 8) by voice. Next, the external telephone (1
6) is received by the control signal receiving section (6) and transmitted to the main control section (4).

The code input to the main control section (4) is the operation setting section (9).
The password is compared with a preset password. If the numbers match, the voice synthesized sound output unit (

Next, after verifying the confirmation number [Figure 3 Step <26]
(27) E. Send message M3 or M4 as a synthesized voice depending on the state of the target device (21) [Step (28) in Figure 3]. Furthermore, when a device number is input, it is verified, the corresponding target device (21) is controlled, and the device status after control is sent as a message M4 or M [Steps (29) (30 in Fig. 3). ) (31) (
32) ).

[Problem that the invention seeks to solve]

Since the conventional telecontrol device operates as described above, the state of the security sensor (19) is monitored only once during one incoming call, as shown in the timing chart of FIG. Therefore, if there is no abnormality at one monitoring timing of the Senna (19) during a relatively long call reception period, no abnormality occurrence will be reported even if an abnormality is detected thereafter. Abnormalities at this time will not be reported unless you call again.

This invention was made in view of the above-mentioned problems, and its purpose is to provide a telecontrol device that ensures that if an abnormality occurs during a call reception period, the caller is informed of the abnormality. .

[Failure to solve the problem]

In this invention, if an abnormality is detected during the incoming call period, a notification of the occurrence of the abnormality is made during the incoming call period.

[Effect]

Even if no abnormality is detected until the middle of the call receiving period, if the abnormality is detected before the end of the call receiving period, that is, before the line is released, the occurrence of the abnormality will be reliably reported to the caller.

〔Example〕

The system configuration including the telecontrol device (15) has already been explained with reference to FIG. 2, and the basic operation of the telecontrol device (15) has also been explained with reference to FIG. Since this explanation is common to the apparatus of the embodiment of the present invention, it will be omitted here.

Figure g1 shows a telecontrol device (15) to which the present invention is applied.
) shows the configuration of What is different from the configuration of the conventional device shown in FIG.
O) is provided, and the main control section (4) executes the abnormality monitoring process shown in the flowchart of FIG. 4 every time the monitor pulse is input.

This abnormality monitoring process is triggered when the main routine reaches step (25) in Figure 3, and thereafter, it is executed in parallel with the main routine every time a monitor pulse of a certain period is input until the line is released. Executed automatically or interruptively.

The abnormality monitoring process reads the output of the security sensor (19) [step (33)), determines whether or not there is an abnormality [step (34)], and if there is an abnormality, sends a security message M to the calling party using synthesized voice. This is a sending process (step (35)). This step (35) is executed with priority over other processes, and even if the main routine is monitoring and controlling the target device (21) and verifying the number, the determination in step (34) will be YES. If so, the main routine is interrupted and step (35) is executed. An example of this operation is shown in the timing chart of FIG. In this example, an error was detected while inputting the device number,
After the device number input is completed, a security message M is sent, and then a device status message M4 is sent.

Next, another embodiment of the invention will be described with reference to FIG.

In this embodiment, the recipient is required to input a termination number before the line is released after the necessary call control operations are completed. When the input of the end number is detected in step (39) in FIG. 9, the process proceeds to step (36), and the security sensor (1
Read the output of step 9) to determine whether there is an abnormality. If there is no abnormality, open the line in step (40). If there is an abnormality, send a security message M, and then proceed to step (40).
40) to open the line.

〔Effect of the invention〕

As explained in detail above, according to the telecontrol device according to the present invention, if an abnormality occurs during a certain call reception period, the abnormality occurrence is reliably reported within that call reception period, so that the abnormality monitoring and reporting function is activated. Reliability is improved as before.
