Abstract

PURPOSE:To simplify a constitution and to prevent the mistake of call switching by judging the identification coincidence and the mode by the first dialing and transmitting the signal of monitor mode by the number of times of receiving of calling sound signals corresponding to the second dialing. CONSTITUTION:In the first number of times judging means 4, the coincidence of the number of times of receiving counted by the number of times detecting means 3 until a time when the suspension of call by the first dialing is detected and secret number of times is decided. When calling sound signals are generated more in the number of times than preset identification number of times for load control by re-dialing telephone number of the control side, a load control signal Vf that inverts the state of operation of a load 11 is outputted from the third number of times judging means 6 at a point of time when calling sound signals corresponding to the second dialing are received seven times. Thereby, the latching relay of a load control means 7 is inverted and an operation detection signal is inputted to a reply control means 9. The reply control means 9 controls a replying means 10 to return an operation confirmation signal to the control side.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a telecontrol device that remotely controls a load via a telephone line.

[Backload technology] Conventionally, this type of telecontrol device remotely controls a load via a telephone line.The control side calls the telecontrol device to put it into a talking state, and receives frequency multiplexed signals or time division multiplexed signals. It was designed to transmit control signals.

That is, when the telecontrol device is called by the control side by dialing, it puts the telephone line into a communication state, receives a control signal sent from the control side, and decodes this control signal to control a predetermined load. Load control 46
It was beginning to form a number. However, such a telecontrol device requires special control signal transmitting means on the control side, and has the disadvantage that the load cannot be remotely controlled from any telephone. In addition, it requires a call switching means to switch between Tsuho telephone calls and control calls, which complicates MIt configuration and increases costs. There was an inconvenience that calls could not be made in some cases. Therefore, in order to solve this inconvenience, it is possible to remotely control the load using the ring tone signal when a telephone call is received, but it is easy to cause malfunctions of the load due to wrong calls or prank calls. Up,
There is a problem in that the operating state of the control IF load cannot be easily checked.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to simplify the configuration and reduce costs by eliminating the need for special control signal transmitting means and call switching means. Telecontrol Vcr! can be made inexpensive, is less prone to malfunction of the load due to wrong calls or prank calls, and can control or monitor the load easily and in a short time! The goal is to provide I.

[Disclosure of the Invention 1 (Embodiment) FIG.
A ring tone pulse V is generated by detecting a 6Hz ringing signal (a signal with a 3-second period that causes a ringing bell to ring for 1 second at 2-second intervals).
Output a. Outputs the number of times detection signal. The first number determination unit 1fi4 determines whether the number of receptions of the ringing tone signal corresponding to the first dialing from the control side is a preset number of control mode passwords, and if they match, a password matching signal is sent. Output Ve. The second number-of-times determining means 5 determines whether the number of times the ringing tone signal has been received is the number of passwords for the monitor mode, and outputs a password matching signal Ve' if they match. The third number of times determination means 6 is the first number of times determination means 4.
When the password matching signal Ve indicating control mode selection is output from It outputs a control signal Vf and controls the load via the load control means 7. On the other hand, if the password matching signal ■e゛ indicating monitor mode selection is obtained from the second determining means 5, the operating state of the load 11 is confirmed! ! J (e.g. on,
Off state! ! Based on the output of the operation detection means 7 for detecting the call, the reply control means 9 controls the timing of setting the telephone #11 to the call state, and the reply means 10 controls the timing of setting the telephone #11 to the call state. corresponding to dialing)
An operation confirmation signal indicating the operation state based on the number of receptions is sent back to the control side via the telephone line 1. Further, after controlling the load 11, the reply control means 9 and the reply means 10 are operated, and an operation confirmation signal is returned at the timing when the telephone set Ml is set to the talking state. The control side can confirm whether the remote control of No. 11 has been performed reliably. In addition, in the embodiment, 4 /JIi;'I Nt b m of the ringing tone signal

．． A voltage proportional to the number of pulses obtained by integrating the ringing tone pulses is compared with a reference voltage generated based on the number of passwords to determine whether the number of receptions of the ringing tone signal and the number of passwords match in an analog manner. It's okay.

The operation of the embodiment will be specifically explained below.

FIG. 2 is a time chart showing the operation of the load 11 in the control mode, and FIG. 2(a) shows the ringing tone pulse Va output from the ringing tone detection means 2;
a is counted by the number detection means 3 for each dialing. Here, the end point of the ringing tone signal for each dialing, that is, the point of time when the control side handset goes on-hook, is determined by whether or not the next pulse is input within 3 seconds from the falling edge of the ringing tone pulse. If there is no pulse input for more than a second, it is assumed that the reception of the ring tone signal due to the last dialing has ended, and the counter is reset, in preparation for counting the number of times the ring tone signal is received due to the next dialing. ing. Figure 2 (
e) indicates the counter reset equal number vc,
The counter is reset when the level is “H”, and the counter is reset when the level is “L”
” Counter count operation is performed when the level is
The counting operation of this ringing tone pulse Va is the ringing tone G?
The signal Vcl with the signal delayed by 0.5see (Fig. 2(d)
It is carried out in synchronization with the rise of the Igbo signal (shown in Figure 1). Further, the first number of times determining means 4 determines whether the number of receptions counted by the number of times detecting means 3 and the number of passwords correspond to the number of times of reception counted by the time when the cancellation of the call due to the first dialing is detected. If the number of times the ring tone A3 corresponding to the second dialing is received is different from the number of passwords, the password matching signal Ve is not output.

Now, when the telephone receiver of the controlling party is taken off-hook and the telephone number of the telephone of the controlled party is dialed, a ringing tone signal is sent from the telephone office to the controlled party via the telephone line 1. On the control side, when the number of ringing signals for this first dialing reaches the preset number of control mode passwords (three times in the embodiment), the handset is turned on and the first dialing is performed. Stop dialing. At this time, on the controlled side, the control mode is selected from the first number determination means 4 because the number of ringing sounds (i4) and the number of passwords for control mode are the same as the first number of dialing (if number is received). A password matching signal Ve indicating
is output. In this manner, when the password matching signal Ve is output from the number of times determination means 4, the determination operation of the number of times determination means 6 of f53 is enabled, and the load control data is set to the acceptable state.

FIG. 2(e) shows the output timing of the password matching signal Ve. Next, on the control side, dial the phone number of the controlled side again (using the redial function) and dial the preset ffi #+E number of times for load control (7 to 7 in the example).
11 times) or more, the operating state of the load 11 is reversed by the third number of times determining means 6 when the ringing sound signal corresponding to the second dialing is received 7 times. A load control signal such as shown in Fig. 2(f)
is output. The load control latching relay of the load control means 7 is driven in reverse by this load control signal Vf,
The operating state of load 11 is reversed (on-off, off-on)
The operation state of the load 11 after the inversion control is detected by the operation detection means 8, and the operation detection signal is sent to the reply control means 9.
is input. Reply control hand! ';l 9, load 11
The timing for putting the telephone line 1 into the talking state is set according to the operating state of the load 11.
is on, when the ring signal is generated 9 times,
When the load 11 is off, the return δ means 10 is controlled to put the telephone line 1 into a talking state when the ringing signal is generated 11 times, and an operation confirmation signal is sent back to the control side. ing. Therefore, on the control side, the operating state of the load 11 can be confirmed by checking how many times the ringing tone signal for the second dialing is generated to reach the talking state. ttfJ2 diagram (I?) is a call control signal, the solid line is the call timing when the load 11 is on, the dotted line is the call timing when the load 11 is off, and the time to put the telephone line 1 into the call state. is set to about 3 seconds in the embodiment, but it goes without saying that it can be set arbitrarily. Note that if it is necessary to notify the control side that the load 11 is in an uncontrollable state, for example, when a ringing signal is obtained three times, the telephone line is put into a talking state and a failure signal is sent back. You can do it like this. In addition, in the embodiment, control is determined by continuous dialing only when the next dialing call is made within 30 seconds after the previous dialing call is cancelled. This prevents malfunctions caused by ringing signals (during control). In other words, the result of determining the number of times ring tone A3 corresponding to the previous dialing was received is valid for 3 () seconds to prevent malfunctions, and t52 (b) shows the continuity of dialing. This is the detection signal vb, and continuity of dialing is guaranteed during the "1-" level, and when it reaches the "H" level, the result of determining the number of times the ringing tone signal was received due to the previous dialing is canceled. It has become.

Next, when the ring tone signal from the first dialing from the control side reaches the preset number of monitor mode passwords (for example, 5 times), if you hang up the telephone receiver and cancel the call, , since the number of times the ringing tone signal has been received matches the number of passwords for monitor mode, the second number of times determining means 5 outputs a password matching signal V indicating monitor mode selection.
e' is output, the reply control means 9 and the reply means 10 are set to the operable state, and the ring tone signal f? corresponding to the second dialing is received. When the number of times reaches a predetermined number, an operation confirmation signal indicating the operating state of the load 11 is returned to the control side via the fi control means 9 and the reply means 10. In this case, the operation confirmation signal return method is is the same as the method of replying the operation confirmation signal in the control mode described above, and when the ring tone signal corresponding to the second dialing is obtained a predetermined number of times, the telephone line is placed in a busy state for a certain period of time and operates. A confirmation signal is returned.When a ring tone signal is obtained from the second dialing a predetermined number of times, the telephone line is put into a communication state and the voice and oscillation generated using the voice synthesis means are returned. The glJ of load 11 is transmitted by transmitting the pitch of the sound, the length of the intermittent period of the oscillation sound, etc.
All operating states may be set to 3.

[Effects of the Invention] As described above, the present invention outputs a password matching ID when the number of receptions of the ringing tone corresponding to the dialing from the controller 1 matches the preset number of passwords. a load control means for controlling the load according to the number of times a ring tone signal is received corresponding to the dialing after the password matching signal is obtained; In a telecontrol device comprising a reply means for placing a telephone line in a talking state for a certain period of time at a predetermined timing and returning an operation confirmation signal, the number of passwords for control mode and the number of passwords for monitor mode are set in advance by the password number setting means. , the mode is determined by the number of times determining means at the same time as the password matching is determined by the first dialing, and the control mode signal is controlled by the number of times the ringing tone signal corresponding to the second dialing is received. It is designed to perform signal transmission in monitor mode that sends back a transmission or load operation confirmation signal, and controls the load based on the number of times a ring tone signal is received by dialing from the control side, and returns a load operation confirmation signal. As a result, the load can be reliably controlled from any telephone without the need for a special control signal transmission means.
It does not require a call switching means, which simplifies the configuration and reduces costs. It also prevents the desired call from being disabled due to a mistake in switching the call switching means. After checking whether the control signal is a legitimate control signal by determining the number of times the ring tone signal corresponding to the first dialing is received, the load control data is inputted. Another advantage is that malfunctions caused by prank calls are less likely to occur.Furthermore, since the mode is determined at the same time as the password matching determination, the load can be easily controlled or monitored in a short time. .
