Embodiment 1 FIG.
FIG. 1 is a block diagram showing a remote monitoring communication control system according to Embodiment 1 of the present invention. In the figure, the automatic notification device 1 is provided with terminals 1a to 1h.

Description of Terminals 1a to 1h The terminal 1a is for receiving monitoring target state information from the monitoring target state detection device 2 (state detection device). The monitoring target state detection device 2 monitors the state of the monitoring target and issues monitoring target state information. In this example, the monitoring target is the elevator 3. The monitoring target state detection device 2 is provided in a machine room, a car, an entrance / exit, a pit, and the like of the elevator 3.

  A remote communication device 6 is connected to the terminals 1b and 1c via the telephone line abnormality detecting device 4 and the telephone line 5. The telephone line abnormality detection device 4 includes a dial tone, a telephone line terminal voltage (voltage between two lines), a ringing tone, a busy tone, congestion (the telephone line is congested), etc., and a telephone line terminal. The inversion of the voltage polarity is detected, and a telephone line detection signal is input to the terminal 1c. The remote communication device 6 is, for example, a communication terminal of a company that manages a building where the elevator 3 is provided.

  An interphone connection circuit 7 is connected to the terminals 1d and 1e. The interphone connection circuit 7 is connected to an interphone 8 (notification device) provided in the car and an interphone 8 provided in a manager room in the building. The automatic notification device 1 can operate the interphone 8 by controlling the interphone connection circuit 7.

  A test request signal from the test button 9 and the periodic signal generator 10 is input to the terminal 1f. The test button 9 issues a test request signal every time the test button 9 is operated. The periodic signal generator 10 issues a test request signal every arbitrary set time. The periodic signal generator 10 generates a test request signal, for example, once a day, several times a month, or every set time. In other words, the arbitrary setting time can be arbitrarily set by the user.

  The lamp 12 is connected to the terminal 1g. An operation clear signal from the data clear button 11 is input to the terminal 1h.

Explanation in the automatic notification device 1 The automatic notification device 1 includes a monitoring data management unit 101, a communication management unit 103, a line abnormality detection unit 104, a notification management unit 105, and a test request unit 106.

  The monitoring target state information input from the terminal 1a is sent to the monitoring data management unit 101 that monitors and stores the monitoring target state information. The monitoring data management unit 101 includes a monitoring data storage unit 102, a monitoring data abnormality determination unit 107, a monitoring data abnormality detection unit 108, and a monitoring data abnormality recognition unit 109. In the monitoring data storage unit 102, monitoring target state information is always stored. If there is a data request instruction from the remote communication device 6, monitoring target status information is transmitted from the monitoring data storage unit 102 to the remote communication device 6.

  In the monitoring data abnormality determination unit 107, the input monitoring target state information is generated within the generation duration time and within a predetermined time according to the level of the monitoring target state information (the degree of quality of the monitoring target state). The number of times is determined. As a result of these determinations, if the monitoring data abnormality determining unit 107 determines that the monitoring target is abnormal, the monitoring data abnormality detecting unit 108 and the monitoring data abnormality determining unit 109 are determined to be abnormal. Information is input as abnormal data. The monitoring data abnormality detection unit 108 detects in what state the monitoring target is in accordance with the inputted abnormality data. This selects where the monitoring target state information should be transmitted, and determines a selection signal (telephone number).

  The monitoring data abnormality recognition unit 109 determines in what state the monitoring target is in accordance with the inputted abnormality data. As a result, the abnormal data is converted into a detection code (for example, fire: code 001, air conditioner failure: code 002).

  For example, if the monitoring target state detection device 2 is a temperature detector, the date and temperature and the temperature are stored in the monitoring data storage unit 102. When the monitoring target state information that the temperature at the elevator detection location is equal to or higher than the set temperature is generated, the monitoring target state information is generated exceeding the set time or the number of occurrences exceeds 10 times in 15 minutes. When the monitoring data abnormality determination unit 107 determines that the elevator state is abnormal, the monitoring target state information that the temperature is equal to or higher than the set temperature is input to the monitoring data abnormality detection unit 108 and the monitoring data abnormality recognition unit 109 as abnormality data. Entered. At this time, it is determined that the monitoring data abnormality detecting unit 108 notifies the building management company of the abnormality to be monitored, and the monitoring data abnormality identifying unit 109 determines the detection code of the abnormal data.

  The selection signal and the detection code are input to the communication management unit 103. The communication management unit 103 includes a dial transmission unit 110, a data transmission unit 111, and a communication control unit 112.

  Dial transmission unit 110 receives a selection signal input from monitoring data management unit 101 and inputs a dial transmission instruction to communication control unit 112. The data transmission unit 111 receives the detection code and holds the detection code. The communication control unit 112 receives a dial transmission instruction, starts communication with the remote communication device 6, and transmits a detection code from the data transmission unit 111.

  A telephone line detection signal from the telephone line abnormality detection device 4 is input to the line abnormality detection unit 104 in the automatic notification device 1 via the terminal 1c. When the line abnormality detection unit 104 determines any failure in the near field switch 13, the remote switch 14, the telephone line 15, and the remote communication device 6, a line abnormality detection signal corresponding to the failure is transmitted to the communication control unit. 112 is input.

  Upon receiving the line abnormality detection signal, the communication control unit 112 inputs the line abnormality detection signal to the notification management unit 105. The notification management unit 105 includes an interphone control unit 113, an announcement content storage unit 114, and a telephone request unit 115. In addition, the notification management unit 105 is connected to the interphone connection circuit 7 via terminals 1d and 1e.

  The announcement content storage unit 114 includes the failure content indicating where the malfunction occurred in the near field switch 13, the far field switch 14, the telephone line 15, and the remote communication device 6, and instructions for dealing with those failures. Announcement content is stored (information regarding abnormal content). For example, if there is a problem with the near field switch 13, there is a problem with the communication circuit up to the near field switch 13. If you want to hear the announcement, please contact company A. The announcement content is stored. If the remote switch 14 could not be connected, “There is a problem with the communication between the exchanges. Please wait for a while, or contact the company A to hear the announcement.” The announcement is stored.

  The line abnormality detection signal is input to the interphone control unit 113. The interphone control unit 113 reads the announcement content from the announcement content storage unit 114 in accordance with the input line abnormality detection signal. In addition, the interphone control unit 113 controls the interphone connection circuit 7 via the terminal 1d.

  The interphone connection circuit 7 is normally set so as to connect the interphone 8 provided in the car and the interphone 8 provided in the manager room. The SW in the interphone connection circuit 7 is controlled by the interphone control unit 113. Thus, the interphone 8 in the car or the interphone 8 in the manager's room is connected to the terminal 1e of the automatic notification device 1.

  The interphone control unit 113 inputs the abnormal content of the telephone line 5 and the corresponding instruction to the interphone 8 through the interphone connection circuit 7. In response to this, the interphone 8 notifies the car or the manager's room where the trouble occurs in the telephone line 5 and a corresponding instruction for the trouble.

  In addition, the interphone control unit 113 can make a call between the car and the remote communication device 6 when the call between the car and the manager room exceeds the set time or when there is a request. In other words, a call can be made between the administrator room and the remote communication device 6.

  The telephone request unit 115 stores a selection signal for the remote communication device 6. The interphone control unit 113 issues a telephone request signal to the telephone request unit 115. The telephone request unit 115 inputs a selection signal to the dial transmission unit 110 by receiving the telephone request signal. As a result, the car or the manager room can communicate with the remote communication device 6.

  A test request signal is input to the test request unit 106 from the terminal 1f. When the test request signal is input, the test request unit 106 inputs an off-hook instruction to the communication control unit 112. Then, the communication control unit 112 goes off-hook, and the telephone line abnormality detection device 4 detects whether there is a dial tone. The detection result is input to the line abnormality detection unit 104 as a telephone line detection signal.

  The line abnormality detection unit 104 determines a telephone line detection signal. That is, the line abnormality detection unit 104 determines whether there is a dial tone. When it is determined that there is a dial tone, a line tone detection signal is input from the line abnormality detection unit 104 to the test request unit 106 via the communication control unit 112. The test request unit 106 receives the dial tone detection signal, turns on the lamp 12 via the terminal 1g, and clears the test request signal. When no dial tone is detected, the lamp 12 is not lit.

  When the automatic notification device 1 receives an operation clear signal from the terminal 1h, the abnormal data, the telephone request signal, and the test request signal are cleared. That is, the input of the selection signal to the dial transmission unit 110 is canceled, and the off-hook by the communication control unit 112 is cancelled. Therefore, the communication and call between the automatic notification device 1 and the remote communication device 6 are canceled.

FIG. 2 is an explanatory diagram showing a communication state between the automatic notification device 1 and the remote communication device 6 performed via the telephone line 5 of FIG. . The automatic notification device 1 is connected to the remote communication device 6 via the near field switch 13 and the far field switch 14.

  The telephone line 15 connected to the automatic notification device 1 has terminals L1 and L2. A DC voltage of 48 V DC is applied from the local exchange 13 between L1 and L2. That is, if the local exchange 13 has not failed, the DC 48V voltage is supplied to the automatic notification device 1. It should be noted that the supply voltage when the local exchange 13 is not out of order is in the range of about 48 ± 5V.

  When the automatic notification device 1 is off-hooked (in other words, when the telephone is disconnected, the receiver is disconnected), a call signal for the local exchange 13 is issued. When an outgoing call is detected in the near field switch 13, the near field switch 13 is activated, preparation for receiving a selection signal (telephone number) is completed, and a dial tone (400 Hz continuous signal) is transmitted to the automatic notification device 1. Is done.

  The automatic notification device 1 detects a dial tone and transmits a selection signal to the local exchange 13. The near exchange 13 connects to the far exchange 14 based on the selection signal. Based on the state of the remote communication device 6, the remote switch 14 selectively transmits to the automatic notification device 1 an announcement (information related to the call) such as a ringing tone, busy tone, or congestion. That is, if the far-end switch 14 has not failed, an announcement such as a ringing tone, busy tone, or congestion is detected.

  If the remote communication device 6 is in a communicable state, a ringing tone is transmitted to the automatic notification device 1 and an incoming call display is displayed on the remote communication device 6. When the remote communication device 6 goes off-hook, it becomes possible to transmit and talk. Further, when the remote communication device 6 goes off-hook, the polarity of the DC voltage applied to the automatic notification device 1 is reversed (response signal). That is, if the remote communication device 6 has not failed, an inversion of the polarity of the DC voltage between L1 and L2 is detected after an announcement such as a ringing tone, busy tone, or congestion is detected.

  Thereafter, when on-hook (put a handset in the case of a telephone) is performed in either one of the automatic notification device 1 and the remote communication device 6, the transmission and the call are ended.

Explanation of Operation FIG. 3 is a flowchart showing the operation of the automatic notification device 1 of FIG. In the figure, the automatic notification device 1 takes in and monitors input data (monitoring target state information) from the monitoring target state detection device 2 (step S101) (normal state). The fetched input data is stored in the monitoring data storage unit 102 (step S102), and the monitoring data abnormality determination unit 107 determines whether or not the input data is abnormal data (step S103). If the input data is not abnormal data, the normal state is restored.

  Here, when the input data is abnormal data, when there is a telephone request signal from the interphone control unit 113 (step S104), or when a test request signal is input to the test request unit 106 (step S105). , Abnormal data, a telephone request signal, and a test request signal are saved (steps S106 to S108) (communication ready state).

  Further, the clearing of the test request signal, the telephone request signal, and the abnormal data clear signal (Step S109) performed by the operation clear signal is interrupted and performed when the communication preparation is completed.

  Next, the presence or absence of abnormal data or a telephone request signal is confirmed in the automatic notification device 1. That is, it is confirmed whether or not the selection signal is input in the dial transmission unit 110 (step S110). Here, it is determined whether the automatic notification device 1 is in a communication ready state due to abnormal data, a telephone request signal, or a test signal, and the subsequent operation changes.

When the communication preparation state is caused by the abnormal data or the telephone request signal When the abnormal data or the telephone request signal is generated, the selection signal is input to the dial transmission unit 110 and the dial transmission instruction is input to the communication control unit 112. . As a result, the communication control unit 112 performs off-hook (connects a line) (step S111).

  Next, the presence or absence of a dial tone is confirmed by the line abnormality detection unit 104 (step S112). Here, it is determined whether or not the telephone line 5 to the local exchange 13 is normal depending on whether or not a dial tone is detected.

  When there is a malfunction in the telephone line 5 to the near branch exchange 13, the dial tone is not detected. Then, the communication control unit 112 performs on-hook, and holds the on-hook for T1 seconds (arbitrary set time) (step S113). This gives a time difference between off-hook and on-hook.

  Then, after maintaining on-hook for T1 seconds, off-hook and dial tone detection operations are performed n times (arbitrarily set times) (step S114). If the dial tone is not detected even after retrying n times, it is determined that there is a disconnection of the telephone line 15 or a failure in the connection portion. Please contact us "is notified in the car or in the manager's room (step S115).

  On the other hand, if a dial tone is detected within n retries, the telephone line up to the local exchange 13 is confirmed normal and the communication preparation complete state is restored, and the presence or absence of abnormal data or a telephone request signal is again confirmed ( Step S110).

  On the other hand, when there is no problem in the telephone line 5 to the near exchange 13 and a dial tone is detected, a selection signal is transmitted from the communication control unit 112 to the near exchange 13 (step S116).

  At this time, whether there is any of a calling signal, busy tone, and voice announcement from the remote switch 14 to the automatic notification device 1 by the line abnormality detection unit 104 and whether there is a response signal (polarity inversion). Is determined (step S117).

  If no response signal is detected, it is monitored whether a response signal is detected for T2 seconds (arbitrary set time) (for example, 2 seconds) (step S118). For example, when a response signal is not detected during T2 seconds, there is a possibility that congestion is occurring (the line is congested). At this time, on-hook is performed for T1 seconds (step S119), and the interphone 8 makes, for example, “It is difficult to communicate with the communication. Etc. "is notified in the car or the manager's room (step S120), and the retry is repeated (steps S110 to S118).

  On the other hand, if any one of the calling signal, the busy tone, the voice announcement, and the response signal is detected, the automatic notification device 1 and the remote communication device 6 can communicate and communicate with each other, and the monitoring data Or a call is started (step S121). Then, it is monitored whether the monitoring data has been transmitted or whether there is a telephone request signal (not on-hook) (step S122). Then, when the monitoring data has been transmitted, or when the call between the car and the remote communication device 6 is finished, it is on-hook (line is disconnected) (step S123).

When the communication request is completed by the test request signal The presence or absence of abnormal data or a telephone request signal is confirmed when the communication preparation is complete (step S110). In this case, there is no abnormal data or telephone request signal. Therefore, the presence / absence of the test request signal is confirmed (step S124). When it is confirmed that there is a test request signal, the communication control unit 112 performs off-hook (step S125), and the presence or absence of a dial tone is monitored (step S126). At this time, the operation when the dial tone is not confirmed is the same as the operation when the automatic notification device 1 enters the communication ready state by the abnormal data or the telephone request signal (steps S113 to S115).

  On the other hand, when a dial tone is detected by the line abnormality detection unit 104, a dial tone detection signal is input from the line abnormality detection unit 104 to the test request unit 106, and the lamp 12 is turned on (step S127). Then, the test request is cleared (step S128), the automatic notification device 1 returns to the communication ready state, it is confirmed that there is no abnormal data or a telephone request signal (step S110), and it is confirmed that there is no test request signal. (Step S124), the automatic notification device 1 returns to the normal state.

When the data clear button 11 is pressed When the operation clear signal is received in the communication ready state and the test request, telephone request, and abnormal data are cleared, it is confirmed that there is no abnormal data or telephone request signal ( In step S110), it is confirmed that there is no test request signal (step S124), and the automatic notification device 1 returns to the normal state.

  In such a remote monitoring communication control system, the line abnormality detection unit 104 can detect the abnormality of the telephone line, the near field switch, and the far field switch, so it can detect where in the communication network the failure occurred. As a result, not only the presence / absence of a failure, but also the abnormality content and the response instruction can be notified, and the reliability of the remote monitoring communication control system can be further increased.

  In addition, since the test request signal is issued from the periodic signal generator 10 every arbitrary set time, the state of the telephone line 5 by off-hook can be performed every arbitrary set time. The conventional device always checks the state of the telephone line 5 by off-hook and is busy when trying to communicate from the remote communication device 6, but this is prevented and the remote communication device 6 automatically Connection to the reporting device 1 becomes possible.

  Further, since the remote communication device 6 can be connected to the automatic notification device 1, the remote communication device 6 can read the data in the monitoring data storage unit 102 at any time, and the remote monitoring communication can be performed. The reliability of the control system can be further increased.

  Furthermore, since the voltage between the terminals of the telephone line 5 is constantly monitored by the line abnormality detecting unit 104, it is possible to check the state of the telephone line 5 for 24h365 without going off-hook. Reliability can be further increased.

  In addition, since the polarity inversion of the voltage between the terminals of the telephone line 5 is detected by the line abnormality detection unit 104, not only the malfunction of the telephone line 5 but also the operation of the remote communication device 6 can be confirmed, so that more detailed abnormality contents The information regarding the remote monitoring communication control system can be further improved.

  In the description of the first embodiment, the automatic notification device 1 checks the presence or absence of a dial tone. However, only the terminal voltage of the telephone line may be confirmed without detecting the dial tone. Thereby, the circuit configuration of the remote monitoring communication control system can be simplified.
