The operation of the control device 4 according to the present invention installed as described above is as follows.

The control device 4 according to the present invention sets up a communication path between the household currency device 1 and the guard room simple switchboard 3 as in the conventional wiring. When the visitor calls a specific household through the common entrance lobby phone 5, the control unit 4 transfers the calling channel of the called household to the common entrance lobby phone 6 and simultaneously transmits the door calling sound to the called household. . The called generation hooks off the handset of the household calling device 1 to enable the call with the common entrance lobby phone 5.

If the called household needs to open and close the hallway after the call, the hook flash is to be hooked up by appointment, and the control unit 4 detects the drive and drives the door. Transmit the signal to open and close the common hall and transmit the open / close confirmation sound to the household to confirm this.

The control device 4 according to the present invention, by detecting the hook flash signal generated for opening and closing the hallway in each generation in this way to control the opening and closing of the hallway, it is possible to use the call line with the existing guard room as it is, each generation Since the generation call equipment installed in the control unit can control opening and closing of the common entrance regardless of whether it is a simple interphone or home automation, there is no need to unify the new wiring or the generation call equipment 1.

Now, with reference to Figures 3 and 4 how the control device according to the present invention is configured to perform the above control function.

3 is a configuration diagram of a control device according to the present invention, in which 10 is a central control device, 11 is a relay driving unit, 12 is a hook on / off detector, 13 is a confirmation sound generator, 14 is DTMF tone generation, 15 is Each ringtone generator is shown.

Looking at the configuration and operation of the control device according to the invention shown in the drawings as follows.

First, the control device 4 according to the present invention usually connects each generation's communication path with the guardboard 2 of the guard room, and when there is a call from the common entrance, the communication path of each generation is installed in the common entrance. A plurality of relay switches RY1 to RYn for switching the call path to the lobby phone 5 side are provided.

And each relay switch (RY1 to RYn) has two switches, one switch for switching the tip line of the two wires connected to the generation, the other for switching the ring line (ring line) It is for. That is, the common terminal of one switch is connected to the tip line of the generation, the normal on terminal is connected to the tip line of the guard room switchboard 2, the normal off terminal is commonly connected to the normal off terminal of the other relay switch. Similarly, the common terminal of the other switch is connected to the ring line of the generation, the normal on terminal is connected to the ring line of the guard room switchboard 2, the normal off terminal is commonly connected to the normal off terminal of the other relay switch.

Therefore, the tip line common contact point (A) and the ring line common contact point (B) which are off are formed, which means that a plurality of generation call paths form a common call path with the common entrance lobby phone (5). do. However, since all relay switches RY1 to RYn are ON at the same time, only one relay switch is controlled to be ON, so that only one generation of calls are made to the common entrance lobby phone 5.

The secondary ring side of the transformer T is connected to the ring line common contact point A, which is formed by these relay switches RY1 to RYn, and the primary side is connected to the communication path of the door lobby phone 5.

The hook-on / off detector 12 is connected to the ring line common contact point B which is turned off to detect the hook on / off of the generation call device 1 in which the common entrance and the call path are set. That is, if there is a generation in which the corresponding relay switch is ON, the ring line common contact (A) is passed through the common line A and the tip communicating unit 1 by the power supply voltage applied to the secondary side of the transformer T. Current flows to B), which flows to ground through resistor R1 in hook on / off detector 12. The resulting voltage drop causes the diode of the photocoupler (PT) to emit light and conduct the transistor through resistor R2, thereby converting the output of the hook on / off detector 12 from 'high' to 'low'. By doing so, the central control unit 10 connected to the output is detected.

Between the primary side of the transformer (T) and the tip line common contact (A), a separate relay switch (RY0) for ring tone switching is installed, which is normally connected to the 1 of the transformer (T). Although the vehicle side and the tip line common contact point (A) are connected, when there is a household call from the common entrance lobby phone (5), it is turned on (ON) by the central control unit (10) that detects the central control unit (10). By connecting the output terminal of the ring tone generator 15, which is controlled by the < RTI ID = 0.0 >), < / RTI > to the tip line common contact A, a ring tone is transmitted to the called generation.

And the opening and closing confirmation tone generator 13 is connected in parallel to the secondary side of the transformer (T) connected to the communication path of the common entrance lobby phone (5), the opening and closing confirmation tone generator 13 is the central control unit (10) Drive under the control of the door) to transmit the opening and closing sound after the operation of the common door opening and closing device through the transformer (T) to the generation side.

In addition, the DTMF tone detector 14 is also connected in parallel to the secondary side of the transformer (T), which is installed to have the optional function for opening and closing the cavity entrance. That is, a generation equipped with a call device equipped with a DTMF tone generator can cause the common entrance opening and closing device 6 to be driven by using a predetermined keypad as well as a hook flash signal. In this case, DTMF from the generation To detect the tone and transmit it to the central control unit 10 to recognize the signal as a hook flash.

The relay drive unit 11 drives a plurality of relay switches RY1 to RYn for switching the call path of the generation, and only one selected from the plurality of relay switches RY1 to RYn under the control of the central controller 10. Drive. The relay switch RY0 for switching the output of the ring tone generator 15 is also driven by the control of the central controller 10.

The central control unit 10 for controlling each of the functional units described above is composed of a microprocessor. Looking at the overall control procedure of the control device 4 of the present invention through the control operation thereof is as follows.

When a visitor visits a multi-unit house and presses a specific household call button through the common entrance lobby phone 5 installed at the front door, this is recognized by the central control unit 10, and thus the central control unit 10 is ringtone. The generator 15 is driven, and the relay switch RY0 for ringtone switching is turned ON and the relay switch for switching the call path of the corresponding generation is driven. The call of the household thus called is connected to the common line of the tip line (A) and the ring line of the common point (B), and is connected to the channel of the common entrance lobby phone (5), but by the ringtone switching relay switch (RY0). Only the calling ring tone is passed to the generation calling device 1.

When the handset of the generation calling device 1 is heard in response to the generation, the ring signal voltage is applied to the resistor R1 of the hook on / off detector 12 and the condenser C for removing the AC component through the generation calling device. The output of the on / off detector 12 is converted to low, and the central controller 10 detects this and stops the operation of the ringtone generator 15 and the relay switch RY0 for ringtone transfer. Is connected to the common entrance lobby phone (5) through the transformer (T). As a result, a call is made between the generation and the visitors of the co-op.

While the call is in progress, the central control unit 10 continuously monitors the output of the hook on / off detector 12. At this time, when the hook on operation of the generation call device is detected, the state is set to several seconds in advance. Monitor for progress. If the hook-on operation of the household calling device 1 continues for several seconds, the central control unit 10 terminates the call because the household is completely closed because the door is not needed to open and close the door after the visitor call in the household. Recognizing as to turn off the relay switch that was driven by controlling the relay drive unit 11 so that the generation call path is connected to the guard room simple switchboard (2). However, if the hook-off state is detected again within a predetermined number of seconds, since the household caller has flashed the hook, the central control unit 10 transmits an operation signal to the common door opening and closing device 6 so that the door opening and closing device is the entrance door. Open the door. In addition, the central control unit 10 controls the opening and closing confirmation sound generating device 13 so that the opening and closing sound is transmitted to the generation call via the transformer (T). The household caller hears the opening and closing confirmation tone, confirms that the door is opened, and ends the call by hooking on. Then, the central control unit controls the relay driving unit 11 to turn off the corresponding relay switch, so that the generation call path is connected to the guard room simple switchboard (2).

4 is a flowchart of a control method according to the present invention.

First, when power is applied, all variables of the central controller 10 and the state of each functional unit are initialized (20). Then, it is checked whether any household is called from the visitor through the common entrance lobby phone 5 (21).

When any household is called from the visitor, the ringtone generator 15 is controlled to transmit the ringtone to the household (22). Check that the household call device 1 in the household receiving the ringtone (1) hooks off (23) when the hook is connected to the call to connect between the generation and the common foyer lobby phone (5). However, if the hook is not off, the visitor continues to send a ringtone while calling, and when the visitor gives up, the call ends and returns (24).

With the passage connected, it is checked whether the household call device 1 of the household is hooked on (26) or whether the specific DTMF tone promised is input from the household (27).

When the call device 1 of the household is hooked on, it is checked whether the state of the telephone device is continuously maintained for a predetermined time (29), and if the hook-on state is maintained for a predetermined time, the common entrance opening (OPEN) is not performed. Since the call is terminated, the call is released (31). However, when the hook is turned off again within a predetermined time (30), which is a hook flash operation for opening the hallway, the door is opened by controlling the opening and closing device (6) and opening and closing sound generator (13). Control to allow the opening and closing confirmation sound to be transmitted to the household communication device (33).

Then, the household telephone device 1 checks whether the hook is turned on (34), and when the hook is turned on, releases the call path (36) and returns. However, if the household telephone device 1 does not change to the hook-on state, it is determined whether the hook-off error has occurred due to a mistake of the household caller through a predetermined check operation, and if it is determined that the hook-off error occurs, the call path is released (36). .

On the other hand, if the generation caller inputs a predetermined DTMF tone promised in advance without a hook flash during the call (27), the same steps 32 and below are performed in the same manner to open the common entrance. If there is no hook flash operation or DTMF tone input in the busy state, a predetermined check is performed to investigate whether a hook-off error occurred by a household caller's mistake. (36) and return.

In the above control procedure, in the method of making a telephone call with a guard room equipped with a revolving switchboard and an individual two-wire system, the hook flash signal can be commonly contracted as an open / close signal regardless of the type of equipment between generations. Since it is used, the step 27 is not an essential procedure by detecting the DTMF input as the cavity door opening and closing signal.

Therefore, the present invention is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the spirit of the present invention. It is obvious to those who have knowledge.

The present invention made as described above has the effect of enabling on / off control of the opening and closing of the entrance hall under the unmanned security system without replacing the existing communication equipment used in the generation or new wiring for opening and closing the entrance hall.
