[0023]
Next, as a premise for explaining the characteristic operation of the present invention, the basic operation of the interphone will be described mainly with reference to FIG. 1, taking a call between the living information board and the front door as an example.
When a visitor operates a numeric keypad (not shown) of the entrance machine EP2 to enter a room number to be visited, for example 102, and then presses the call switch, the room is transferred from the entrance machine EP2 to the call control device TC via the control line L11. A call signal comprising a code and a call code is transmitted.
When the call control device TC receives the call signal from the entrance machine EP2, the call control device TC checks the available call line and video line. For example, if the second call line and the second video line are in use, the call signal and the first call line are used. A call / video line designation command for the line L22 and the first video line L42 is sent to the control line L12, and a video line designation command for the first video line L41 is sent to the entrance machine EP2 via the control line L11. Also, a command for connecting the first video lines L41 and L42 is sent to the video control device VC.
As a result, the entrance machine EP2 activates a television camera (not shown), connects the first video line L41 with a switch (not shown), and sends a video signal of the visitor to the first video line L41.
[0024]
In addition, the living information board J2 in the room No. 102 uses the call signal received through the control line L12 and the call / video line designation commands for the first call line L22 and the first video line L42, and switches for call and video (not shown). To control the first call line L22 and the first video line L42. In addition, a ringing tone is emitted from the speaker 33, the lobby lamp 35b is turned on, the monitor television 31 is activated, and an image based on the video signal sent through the first video line L42 is broadcast.
[0025]
When the handset 39 is picked up by the house information board J2, a hook-off signal is sent from the house information board J2 to the call control device TC via the control line L12. When the call control device TC receives a hook-off signal from the house information board J2, the call control device TC sends a call line designation command for the first call line L21 to the entrance machine EP2, and the entrance machine EP2 controls a switch (not shown) by this command. One telephone line L21 is connected. As a result, a communication path is formed between the entrance machine EP2 and the house information board J2, and a call is performed between the visitor and the occupant in the 102nd room.
If there is an automatic door for entrance at the main entrance, operating the unlock switch 37e of the house board J2 will send an unlock signal to the electric lock of the entrance machine EP2 via the control lines L12 and L11, and the automatic door will Opened.
[0026]
When the call is finished and the handset 39 of the house information board J2 is returned to the original state, a call end signal is sent from the house information board J2 to the call control device TC via the control line L12. An end command is sent to L11, L12 and the video controller VC. As a result, the entrance machine EP2 turns off the TV camera and opens the connection switch between the first call line L21 and the first video line L41, and the house information board J2 turns off the monitor TV and the first call line L22 and the first call line L22. Each connection switch of the video line L42 is opened, and the video control device VC releases the connection between the first video lines L41 and L42. As a result, the first call line and the first video line are released.
The basic operation of the interphone has been described above, and the call control device TC performs the same operation except for the video, even in the call between the living information board J2 and the manager room SM1 described below.
[0027]
Next, the operation when the manager room SM1 is called from the house information board J2 will be described. 5 and 6 are flowcharts of the processing operation of the manager room SM1, FIG. 5 mainly shows processing when a call is made from the housing information board J2, and FIG. 6 mainly shows the processing from the housing information board J2. It shows the processing associated with the operation when the manager who was absent at the time of calling returns.
First, the process of the manager room SM1 when there is a call from the house information board J2 will be described with reference to FIG.
[0028]
The microprocessor (MPU) 1 of the manager room unit SM1 determines whether a call signal is received from the entrance unit EP, the house board (unit of residence) J or the door phone (not shown) of the manager room (S1). ), When the call signal is not received, the following processing (1) and subsequent steps shown in FIG. 6 are executed. If it is determined in S1 that the call signal has been received, it is determined whether the signal is a signal from the living board J (S3). In the case of a management room doorphone, corresponding call processing is executed (S5). Here, the call process is the process shown in the above description of the basic operation of the intercom.
[0029]
If it is determined in S3 that the signal is from the housing information board J, it is necessary to inform the manager that the call has been made when the call from the dwelling unit is necessary, that is, when the manager is absent. A timer for measuring a predetermined time (for example, 30 seconds) for determining whether or not the call is urgent is turned on (S7). Thereafter, it is determined whether or not the handset 22 has been picked up within a predetermined time (S9). If the handset 22 has been picked up, a call process is performed with the calling information board (S5), and the timer is cleared (S5). S19). Further, if the handset 22 is not picked up within a predetermined time on the manager room SM1 side, whether or not the call end signal transmitted when the handset 39 of the housing information board J is returned on the dwelling unit side is received. Judgment is made (S11), and when this signal is received, the timer is cleared (S19).
[0030]
If it is determined in S11 that the call end signal has not been received, it is determined whether or not a predetermined time has elapsed (S13). If the predetermined time has not elapsed, the processes in and after S9 are performed. repeat. If it is determined in S13 that the predetermined time has elapsed, the dwelling unit number of the called house information board J and the current time are stored in the RAM 7 (S15), the memory lamp 11g is turned on (S17), and the timer is cleared. (S19).
[0031]
The above is a description of the processing of the manager room SM1, but as a resident's operation, when the manager is called but the manager is not present, the manager room can be accessed from the residence information board J when the manager is unavoidable. The machine SM1 is called to maintain the calling state (the state in which the handset 39 of the housing information board is picked up) for a predetermined time or more even when the manager does not appear. As a result, the manager room SM1 determines that the timer has elapsed, that is, that the calling state means contact is required, and the memory lamp 11g is turned on. By seeing the lighting of 11g, you know that there is a dwelling unit that you want to contact the manager.
[0032]
Next, based on FIG. 6, the process of the manager room SM1 when the manager is absent and when the manager who was absent returns will be described.
It is determined whether or not the handset 22 has been picked up (S21). If it is determined that the handset 22 has not been picked up, it is determined whether or not a memory switch has been input (S23). Here, the memory switch refers to a code number set in advance from the numeric keypad 13 in order to know a dwelling unit requiring communication. If it is determined in S23 that there is no input from the memory switch, it is determined whether there is a batch erase input instructing batch erase of data in the RAM 7 (S31), and if it is determined that there is no batch erase input. Holds the state as it is and returns to the processing of FIG.
The above-described processing after S21 is processing when the manager is absent or when no operation is performed on the manager room machine SM1 even if the manager is present.
[0033]
If it is determined in S31 that there is a batch erase input, the data stored in the RAM 7 is cleared (S33), and the memory lamp 11g is turned off (S49).
If it is determined in S23 that there is an input from the memory switch, the first dwelling unit number is read from the data stored in the RAM 7 and the dwelling unit number and time are displayed on the display unit 9 (S25). At this time, only the unit number may be displayed.
[0034]
After the dwelling unit number and time are displayed on the display 9, it is determined whether or not there is an input from the next display switch 15c (S27). If there is an input, the next data stored in the RAM 7 is read and displayed. The data is displayed on the device 9 (S29). If it is determined in S27 that there is no input from the next display switch 15c, the process proceeds to S31, and thereafter the processing as described above is performed.
When the next display switch 15c is not operated for a predetermined time, for example, 10 seconds, or when another operation, for example, a handset is picked up, the display on the display 9 is automatically erased and the house number stored in the RAM 7 is displayed. The operation to end is completed.
[0035]
The processing after determining that the memory switch has been input in S23 described above is processing based on an operation performed by the manager when the manager returns from going out and notices the lighting of the memory lamp 11g. In this case, as the manager's operation, when he notices that the memory lamp 11g is turned on, he enters the code number as the memory switch, confirms the called house number displayed on the display 9, and further displays The switch 15c is turned on to check whether there has been a call from another dwelling unit. By such an operation, the manager can easily know the dwelling unit number that has been called.
[0036]
If it is determined in S21 that the handset 22 has been picked up, it is determined whether or not a dwelling unit number has been input (S35), and the dwelling unit number that has been input is displayed on the display unit 9 (S37). When it is turned on, a call signal is transmitted to the house information board designated by the house number, for example, the house information board J2 to perform the house call processing (S39), and it is determined whether or not there is a call (S41). To determine whether or not there is a call in S41, the handset 39 of the house information board J2 is picked up by a call signal from the manager room machine SM1, and a call can be made between the manager machine SM1 and the house information board J2. After that, it is determined that there is a call when the handset 22, 39 of either the manager room SM1 or the house information board J2 is returned and the call state is terminated.
[0037]
If it is determined that there is a call in S41, it is determined whether or not the dwelling unit number of the dwelling board J2 input in S35 is stored in the RAM 7 (S43). The house number and time data are deleted from the RAM 7 (S45). After the process of S45, it is determined whether or not there is data of another dwelling unit number in the RAM 7 (S47). If there is no data, the memory lamp 11g is turned off (S49).
If it is determined in S35 that no dwell unit number has been input, or if it is determined in S41 that there is no call, it is determined in S43 that the dwelling unit number of the dwelling board J2 input by the process of S35 is not stored in the RAM 7. If this is the case, or if it is determined in S47 that no other data is stored in the RAM 7, the process returns to S1.
[0038]
The processing after determining that the handset 22 has been picked up in S21 described above is processing when the manager contacts the residence information board J from the manager room SM, but the manager's operation is as described above. When contacting the dwelling unit that requested the call in the processing after S23, the dwelling unit number displayed on the display unit 9 is input from the numeric keypad 13 in the processing after S23 and the call switch 15h is pressed. If the telephone becomes ready and then the handset 22 or 39 is returned, the dwelling unit number is automatically deleted from the RAM 7. Therefore, the administrator does not need to perform an operation for erasing data. If the number entered by the administrator to contact the resident is not the number stored in the RAM 7, the data in the RAM 7 is not erased.
[0039]
As described above, according to the present embodiment, in the case where the manager board machine SM1 is contacted from the house information board J, the manager room machine SM1 even if the manager cannot make a call due to the absence of the manager. It is possible to keep a history of which house information board J has called, and to be able to contact immediately when the manager returns from the outside, so it is possible to keep in touch smoothly.
Further, in the present embodiment, since not only the dwelling unit number but also the time is stored in the RAM 7 of the manager room SM1 and displayed on the display unit 9, what information is also given as the manager. Easy to understand.
[0040]
In the above embodiment, the example of batch erasure is shown as a method of erasing the dwelling unit data in the RAM 7 by inputting a code. However, only the dwelling unit number to be erased may be individually erased. In this case, for example, when the dwelling unit number is displayed on the display 9 by the process of S25, the data of the dwelling unit number being displayed may be erased from the RAM 7 by inputting the cancellation code from the numeric keypad 13.
[0041]
Further, in the above embodiment, when the memory switch is turned on, an example of input from the numeric keypad is shown as an operation for erasing data from the RAM 7 collectively or individually. An independent switch may be provided as a memory switch for reading and displaying, a batch erase switch, or an individual erase switch.
[0042]
Further, in the above embodiment, when data (unit number) is stored in the RAM 7, the memory lamp 11g is simply turned on regardless of the number of data, but the memory lamp 11g It may be possible to identify the number of data stored in the RAM 7 by using two types of lighting: flashing and continuous lighting.
[0043]
Further, in the above-described embodiment, the dwelling unit number that is called when the manager room device SM1 does not appear for a preset predetermined time in response to a call from the house information board J is stored in the manager room device SM1 side. However, if a memory set switch is provided in the house information board J and the memory set switch is pressed, the house unit number that has been called can be stored on the manager's room SM1 side even if a predetermined time has not elapsed. It may be. This is convenient because it is not necessary to call the manager room device SM from the dwelling unit again in anticipation of the end of the call of the manager room device SM when the manager room device SM is busy.
