Abstract

PURPOSE:To easily and quickly select and control plural loads by selecting a load according to the number of times of receiving calling sound signals corresponding to odd number-th dialing after obtaining an identification code coincidence signal, and controlling the selected load based on the number of times of receiving calling sound signals by even number-th dialing. CONSTITUTION:In case of controlling plural loads 11 continuously, calling sound signals for selecting a load 11 to be controlled next are generated specified number of times corresponding to the selected load 11 by odd number-th dialing after obtaining an identification coincidence signal Ve. Then, calling sound signals that control the selected load 11 are generated specified number of times by even number-th dialing after obtaining the identification coincidence signal, and the selected load 11 is inversion controlled and an operation confirmation signal that indicates the state of operation is returned. By similar way, plural loads 11 can be controlled continuously. In this case, by performing identification coincidence judgement at first, succeeding load selection and control can be made successively with out making the identification coincidence judgement.

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.

[Background Art] Conventionally, in this type of telecontrol device that remotely controls a load via a telephone line, the control side calls the telecontrol device to put it into a talking state, and transmits a frequency multiplexed signal or a time division multiplexed No. 48 signal. It was designed to transmit various 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. It was designed to generate a load control signal to However, such a telecontrol device requires special means for transmitting control signals on the control side, and has the disadvantage that the load cannot be remotely controlled from any telephone bill. In addition, a call switching means is required to switch between normal telephone calls and control calls, and Keisei is unable to do so. ! In addition to being complicated and expensive, switching errors such as forgetting to switch are likely to occur, and desired calls may not be made.

[Objective of the Invention 1 The present invention has been made in view of the above points, and its object is to remotely control the load from any telephone without requiring special control signal sending means or call switching means. In addition to simplifying the configuration and reducing costs, there is no possibility of call failure due to switching errors, and load malfunctions due to wrong calls or prank calls are less likely to occur.
Another object of the present invention is to provide a telecontrol device that can easily and quickly selectively control a plurality of loads.

[Disclosure of the Invention 1 (Example) FIG. 1 is a block circuit diagram showing the configuration of the present invention, in which the ring tone detection means 2 is configured to detect a ring tone transmitted through a telephone line l.
A ringing tone signal of 6 Hz (No. 13 with a 3-second cycle that rings a ringing bell for 1 second at 2-second intervals) is detected and a ringing tone pulse Va is output. The number detecting means 3 is formed, for example, by a counter that counts the ringing tone pulse Va, and outputs a signal of the number of times the ringing tone pulse Va has been received. @1 frequency determining means 4 determines whether the number of times the ringing signal is received corresponding to the first dialing from the control side is a preset first password number, and if they match, a password matching signal is generated. Ve
Output. When the password matching signal Ve is obtained, the number of times determining means 5 at t52 selects the load 11 to be controlled from among the plurality of loads 11 according to the number of times the ringing tone signal corresponding to the subsequent odd-numbered dialing is received. is determined, and the load control means 7 is set to a state in which the selected load 11 can be controlled.

The third number of times determining means 6 is controlled by the password matching signal Ve being output from the number of times fq flattening means of Pt51 and the load selection signal being outputted from the second number of times determining means 5 by the subsequent odd-numbered dialing. When load 11 is selected, the number of receptions of the ring tone signal corresponding to the next even-numbered dialing is determined, and if the preset number of receptions is obtained, load control 1 (Ft number Vf is and controls the selected load 11 via the load control means 7.The operation detection means 8 detects the operating state of the selected load 11 (for example, on,
OFF state) and sends an operation detection signal to the reply control means 9. The reply control means 10 controls the timing at which the telephone line 1 is set to the call state based on the operation detection signal, and the reply means 10 controls the timing of setting the telephone line 1 to the call state, and outputs a ring tone signal (corresponding to an even-numbered dialing) from the reply means 10 to the call state. An operation detection signal indicating the operation state based on the number of occurrences is sent back to the control side via the telephone line 1.

In addition, in the embodiment, the coincidence judgment between the number of receptions of ringtone A3 and the number of passwords is performed digitally using a counter, but a voltage proportional to the number of pulses obtained by integrating the ringtone pulse Va is used. may be compared with a reference voltage generated based on the number of passwords to determine whether the number of times the ringing tone signal has been received and the number of passwords match in an analog manner.

The operation of the embodiment will be specifically explained below.

6) is a ringing line pulse Va outputted from the ringing tone detecting means 2, and this ringing tone pulse Va is counted by the number detecting means 3 for each dialing. Here, at the end of the ring signal due to each dialing, α
In other words, the point in time when the receiver on the control side goes on-hook is determined by whether or not the next pulse is input within 3 seconds after the falling edge of the ring tone pulse, and if there is no pulse power for more than 3 seconds, the current dialing is terminated. The counter is reset as if the reception of the ringing signal has been completed.
Preparation is made for counting the number of times a ringing tone signal is received during the next dialing.

@2 Figure (c) shows the counter reset signal Vc. The counter is reset when it is +'+H'' level, and the counter is reset when it is at IIL'' level) 'jr
h operation is performed, and this counting operation of the ringing tone pulse Va is performed using a signal Vcl which is a ringing tone signal delayed by 0.5 seconds.
(<H number shown in FIG. 2(d)) is performed in synchronization with the rise of the signal. In addition, the first number of times determining means 4 determines whether the number of received fi3 calls counted by the number of times detecting means 3 and the number of passwords correspond to the number of calls counted by the number of times detecting means 3 until the cancellation of the call due to the first dialing is detected. If the number of times the ringing tone signal corresponding to the first dialing is received is different from the number of passwords, the password matching signal Ve is not output.

Now, when you take off-hook the handset of the controlling telephone and dial the telephone number of the controlled telephone, a ring tone signal is sent from the central office to the controlled party via telephone #i[1. . On the control side, when the number of ringing signals for the first dialing reaches a preset number of times (in the example, ;) times), the control side puts the handset on hook and returns the ring tone signal for the first dialing. Abort the call.

At this time, on the controlled side, since the number of times the ringing tone signal is received by the first dialing matches the number of times of the password, the first number of times determining means 4 sends the password as shown in FIG. 2(e). The matching partner number Ve is output. Next, when the controlling party dials the controlled party's telephone number again (for example, by using the redial function) and the second ring signal is generated twice, the controlling party puts the receiver on hook and dials the telephone number of the controlled party again (for example, by using the redial function). When the calling by dialing is stopped, on the controlled side, the second determining means 5 determines the number of times the ringing tone signal corresponding to this second dialing is received, outputs a load selection signal, and outputs a load selection signal to the load controlling means. 7 is set to a state where the second load 11 can be controlled. Next, the control side dials the phone number of the controlled side again and selects the preset FIm+? When a ringing signal is generated more than the number of times LE (5 times in the embodiment), when the ringing signal corresponding to the third dialing is received 5 times, the load is determined from the third number of times determining means 6. Fig. 2 (f
) is output. This load control signal Vf drives the selected load control latching relay of the load controller 19.7 in reverse, and the operating state of the selected load 11 is reversed (on-off, off-on). The operation state of the selected load 11 after the inversion control is detected by the operation detection means 8, and an operation detection signal is input to the reply control means 9. In the reply control means 9, the selected load 11
The timing for putting the telephone 1 into the talking state is set according to the operating state of the telephone 1. In the embodiment, when the selected load 11 is on, the load 11 is off, when the ringing signal is obtained nine times, the replying means 10 is controlled to put the telephone set M1 into a talking state at α, and an operation confirmation signal is sent back to the control side. There is. Therefore, on the control side, the operating state of the load 11 can be confirmed based on the number of ringing signals for the third dialing when the call state is reached. FIG. 2(g) shows the call control number, the solid line is the call timing when the load 11 is on, and the dotted line is the call timing when the load 11 is off, and the telephone line 1 is in the call state. The time for this is set to about 3 seconds in the example, but it can be set arbitrarily.
It's no good. Note that if it is necessary to notify the control side that the selected load 11 is in an uncontrollable state, for example, the telephone line 1 may be disconnected when a ring tone signal for the third dialing is obtained three times. It is also possible to make the communication state and return a failure signal.

By the way, when controlling a plurality of loads 11 in succession, the load 11 to be controlled next is selected by the fourth dialing (the odd-numbered dialing after the password matching signal Ve is obtained). Selected ring signal for load 1
Next, by the fifth dialing (the even-numbered dialing after the password matching code ve is obtained), a ringing tone signal for controlling the selected load 11 is generated a predetermined number of times corresponding to the selected load 11. Selected load 11
The controller inverts the controller and returns an operation confirmation signal indicating its operating state. In the same way, multiple loads 11 can be controlled continuously, and in this case, if a password match is determined first, selection control can be performed sequentially without having to perform a password match during subsequent load control. This means that the load 11 can be controlled quickly. Note that pattern control of a plurality of loads 11 or a predetermined number N of ring tones δ for turning on or off all loads 11 may be generated at odd-numbered dialing,
In this case, the predetermined number of times N is larger than the number M of loads 11 (for example, if there are 10 loads 11, 11 times or more)
is set to In addition, at the end of the continuous control, the odd numbered ring tone (R number) is set to a predetermined number greater than N (for example, N
+1), and when a predetermined number of ringing signals are received for an odd number of dialings, the second number of times determining means 5 generates a control end signal V.
e' is output, the password matching determination result of the first number of times determining means 4 is canceled, and the process returns to the standby state. However, in the embodiment, if the next dialing call is made within 30 seconds after the previous dialing call is canceled, it is considered to be continuous dialing control, so that the normal call is stopped. This system is designed to prevent malfunctions due to ringing signals during dialing (when not under control), so if a dialing ringing signal is not received for 30 seconds or more, the device automatically returns to the standby state. In other words, the result of determining the number of times a ringing signal has been received corresponding to the previous dialing is valid for only 30 seconds to prevent malfunctions, as shown in Figure 2 (b).
) is the dialing continuity detection signal vb, “L”
The continuity of dialing between levels is maintained, and when the level reaches "H", the result of determining the number of times the ring tone signal has been received due to the previous dialing is canceled, so the control is instructed to end. Even if you forget to dial, the continuous control operation is automatically canceled after 30 seconds to prevent malfunctions due to operational errors.

Effect 1 of the Invention F As described above, the present invention generates a password matching signal when the number of receptions of the ring tone signal corresponding to the dialing of 1 time f, 1 from the control side matches the preset number of passwords. a first number of times determination means to output, and a load selection signal that selects a load according to the number of times a ringing tone signal is received corresponding to an odd numbered dialing after a password matching signal is obtained by the first dialing; a second number of times determination means for outputting, and a third means for outputting a load control signal for controlling the selected load based on the number of times the ringing tone signal is received by the even numbered dialing.
and a reply means for returning an operation confirmation signal to the telephone line for a certain period of time at a predetermined timing based on the operating state of the load controlled by the load control signal. Since the load is controlled by the number of times a ring signal is received by dialing from the side, the load can be controlled from any telephone without the need for a special control No. 43 transmission means or call switching means, and the hη structure In addition, it is possible to reduce the cost by checking whether the regular control W signal is received by determining the number of times the ring tone signal corresponding to the first dialing is received, and then transmitting the control data. Since we have an on-call system, malfunctions may occur due to wrong calls or prank calls. Furthermore, the load is selected according to the number of times the ring tone signal corresponding to the odd-numbered dialing after the password matching signal is obtained, and the ringing tone signal corresponding to the even-numbered dialing is selected. Since the selected load is controlled based on the number of receptions of
This has the advantage that a plurality of loads can be easily and quickly selected and controlled.
