Description

  The present invention relates to a communication system of an automatic notification device that monitors criminal acts such as stores and houses and occurrences of abnormalities related to equipment and notifies a predetermined report destination via a telephone line.

  As communication means for telephone lines used by automatic notification devices, there are conventionally known methods for making a voice report on an analog line, and for making a report by packetizing data using an ISDN line. With the development of technology, there is also known one using new communication means such as analog line ADSL communication or communication using an optical communication cable (for example, see Patent Document 1).

  However, in these automatic notification devices, the main control device itself that performs abnormality detection is developed as a new terminal in order to cope with new communication means. As a result, it is necessary to replace the terminal device with a new one in order to cope with the communication means of the telephone line that is evolving day by day.

  However, in the present situation where the terminal device is highly functional and expensive, the terminal device of the old communication means is inevitably continued to be used, and in many cases, the merits of the new communication means cannot be utilized.

  Also, even when the transmitter is prepared separately, it is used to efficiently send and receive a lot of abnormal information unique to the automatic notification device and a lot of setting information for automatic operation management. A communication method between the transmitter that depends on the communication means of the telephone line and the main controller that detects anomalies has been developed individually, and a communication method that can be used in common by the automatic notification device corresponding to various communication means of the telephone line Was not established.

JP 2002-111889 A

  Establish a common communication system that can use the automatic notification device that has been used in the past when you want to use new communication means for telephone lines in the above background, or when a further improved communication means is invented in the future. Therefore, it is desired to construct an inexpensive automatic notification device that enables the use of the latest communication means.

  Low-speed serial communication is generally used as an extensible communication method for automatic notification devices that have been used in the past, but there is a lot of information in automatic notification devices that need to constantly monitor the status of various sensors. At the same time, it is necessary to always transmit and receive as the latest information, and it is desirable to establish a very efficient communication method.

  In addition, as characteristics of information processed by the automatic notification device, there are information that needs to be surely notified to the other party of the occurrence and information that does not need to be recognized whether or not it has been transmitted to the other party. When these are handled as separate communication telegrams, a situation occurs in which only one of the information can be transmitted due to timing restrictions in low-speed serial communication. Therefore, it is desirable to use a telegram format in which information that requires a response and information that does not require a response can be transmitted at the same time, and the response can be transmitted simultaneously with other information.

  Furthermore, in the automatic notification device that performs setting and control remotely from the receiving base, in addition to a response for recognizing that it has been communicated to the other party, information for notifying whether the setting or control has succeeded or failed after that In general, it is necessary to construct a complex sequence. Therefore, it is desirable that information for abnormality detection can be always transmitted and received in parallel during low-speed serial communication while information transmission and reception for setting and control is performed. A message format that can be sent simultaneously is required.

  In order to enable the use of the latest communication means in an automatic notification device that reports to a predetermined notification destination through a telephone line, the present invention provides a communication unit of a main control device of a conventional automatic notification device and a new one. Establish a high-efficiency automatic notification device communication system that connects a transceiver compatible with communication means to realize a common communication system and enables simultaneous transmission and reception of many types of information between the two. For the purpose.

  The communication method of the automatic notification device according to the present invention includes a main control device that monitors the state by connecting various sensors that detect criminal acts and occurrence of abnormalities related to equipment, and abnormality occurrence information detected by the main control device. A communication method for an automatic notification device that assumes low-speed serial communication with a transmitter / receiver that transmits status information to a receiving base device using a communication line, and transmission from the transmitter / receiver to the main controller A communication sequence is composed of a response from the main controller to the transmitter / receiver, the main controller transmits a response message to the transmitter / receiver in response to reception of a transmission message from the transmitter / receiver, and the transmitter / receiver responds from the main controller. The next transmission is performed after the elapse of a predetermined time with respect to reception of the message, and when there is no response from the main control device, the communication sequence is maintained by performing the next transmission after the elapse of the predetermined time from the previous transmission, The transmission message from the receiver is the transmitter / receiver side event information that needs to be confirmed by the main control unit, and the main control unit side event information for confirmation of the reception of the main control unit side event information in the response message from the main control unit And the transmitter / receiver side status information that does not require reception confirmation, the response message from the main controller is the main controller side event information that requires reception confirmation at the transmitter / receiver, and the transmission message from the transmitter / receiver. The transmitter / receiver side event information for confirmation of reception of the middle transmitter / receiver side event information and the main controller side state information that does not require reception confirmation are configured.

  According to the above configuration, since a simple and light-load communication sequence is obtained by pairing a single-type transmission message from the main controller and a single-type response message from the transceiver, the automatic notification used in the past is used. With only minor software changes in the communication unit to support this communication method while continuing to use the device, it is possible to prepare an inexpensive transceiver that can be connected to this and used as a communication means for a new public line. It is possible to cope with the latest communication means while suppressing investment.

  In addition, in the single-format transmission message from the main controller and the single-format response message from the transceiver, event information that requires reception confirmation and status information that does not require reception confirmation are separated, and event information Because it consists of event information for information transmission and event information for reception confirmation, it is possible to simultaneously perform the occurrence of abnormality, its recognition response, and subsequent status monitoring while maintaining the same communication sequence Thus, a highly efficient communication method capable of simultaneously transmitting / receiving various types of information is obtained.

  In the present invention, the transceiver-side event information includes setting information for automatic operation of equipment. According to this configuration, information for performing remote setting of automatic operation of equipment connected to the main controller from the transceiver is transmitted by the event information on the transceiver side, and the main controller confirms the reception on the transceiver side. After responding with the event information, when the setting is completed, it is possible to transmit the setting information of the automatic operation of the equipment while simultaneously transmitting and receiving the abnormality occurrence information by notifying the completion of the event by the main controller side event information. Become.

  Further, the transmitter / receiver side event information includes reference request information of the automatic operation setting result, and the main controller side event information includes reference response information for the reference request information. According to this configuration, when remote setting of automatic operation is performed, the reference request information of the setting result is transmitted from the transceiver to the main control device by the transmitter-side event information together with the setting request information, and the main control device transmits the information indicating the reference answer to the main control. By transmitting the event information on the device side, it is possible to transmit / receive information on the setting contents in both directions while effectively using a small message length.

  In the present invention, the transmitter / receiver side event information includes control information of equipment. According to this configuration, the remote control information is transmitted from the transmitter / receiver to the main control device by the transmitter / receiver side event information, and the main control device performs control after responding to the reception confirmation by the transmitter / receiver side event information. Can be recognized from the transmitter / receiver side based on the state information on the main controller side, so that the control information of the equipment can be transmitted while simultaneously transmitting / receiving the abnormality occurrence information.

  In the present invention, the main control device side event information includes ID information for specifying an operator. According to this configuration, both information indicating that the operation has been performed and information indicating the ID for identifying the person who performed the operation can be transmitted while simultaneously transmitting and receiving other abnormality occurrence information. It becomes possible.

  According to the present invention, it becomes a new public line communication means only by a slight software change of the expandable communication unit to support this communication method while continuing to use the automatic notification device that has been conventionally used. An inexpensive transmitter / receiver can be prepared, and it becomes possible to cope with the latest communication means, and capital investment can be suppressed.

  Further, according to the present invention, event information that requires reception confirmation and status information that does not require reception confirmation are separated from each other in the transmission message from the main controller and the response message from the transceiver, and the event information is information Since it is composed of event information for transmission and event information for confirmation of reception, it is possible to simultaneously perform the occurrence of abnormality, its recognition response, and subsequent status monitoring while maintaining the same communication sequence, A highly efficient communication method capable of simultaneously transmitting and receiving various types of information is obtained.

  Furthermore, according to the present invention, the automatic operation setting of equipment and remote control information or reference command information are transmitted from the transceiver to the main controller, and the operation status information and reference response information are transmitted from the main controller to the transceiver. Alternatively, it is possible to transmit ID information that identifies the operator while simultaneously transmitting and receiving error occurrence information, reducing operational costs for setting changes and facilitating emergency response by remote control Thus, the processing load of the automatic notification device can be reduced and the information acquisition frequency can be improved.

  FIG. 1 is a block diagram showing a system configuration example of an automatic notification device using the present invention. In FIG. 1, a main controller 1 and a transceiver 2 that perform abnormality detection and automatic operation management are arranged in a store 101 or the like to be monitored, and the main controller 1 performs abnormality detection and automatic operation. Are connected to the transmitter / receiver 2 via the telephone line 102, and the receiving base device 4 arranged at the receiving base 103 is connected to the main controller 1. Communication using the communication method of the present invention is performed on the communication line 3 connecting the machines 2.

  The main control device 1 is a device in which only a communication control function according to the communication method of the present invention is added to a conventional terminal device that realizes an abnormality detection function and an automatic operation management function, and the transceiver 2 is a communication means of a telephone line 102. Is a device that performs transmission / reception by converting information transmitted / received by the communication method of the present invention in accordance with the communication means.

  FIG. 2 is a diagram showing a communication sequence used in the communication method of the present invention. The basic sequence is transmitted from the transmitter / receiver 2, the main controller 1 responds immediately after reception, and the transmitter / receiver 2 performs the next transmission at a constant time interval T1 from the reception of the response, and always transmits this response. Repeat. If there is no response from the main controller 1, the transmitter / receiver 2 performs the next transmission at the time interval T2 from the previous transmission, so that the communication sequence in the same message format is always repeated.

  In the communication system of the present invention, the transmitter / receiver 2 always communicates with the main controller 1 repeatedly in the same message format regardless of whether or not an abnormality has occurred, and the main controller 1 has no abnormality. If there is not, information indicating abnormality is not given, and a response in a predetermined message format is always repeated.

  When the main control device 1 detects some abnormality and the abnormality needs to be notified to the receiving base device 4 via the transceiver 2, it is performed from the transceiver 2 immediately after the abnormality is detected. In the response of the main control device 1 to the first transmission, the corresponding information in the event area in the message is changed to the abnormality occurrence state, and a response is made.

  The transmitter / receiver 2 constantly monitors the information of the event area included in the response from the main control device 1, and if there is information that has changed to an abnormality occurrence state, the transmitter / receiver 2 transmits to the receiving base device 4 according to the communication means of the telephone line 102. At the same time as transmitting the occurrence of an abnormality by the method, at the time of transmission to the next main controller 1, the information of the event area assigned to the same position as the received abnormality occurrence information is changed to the abnormality occurrence state and transmitted. Thus, the main controller 1 is notified that the reception has been normally performed.

  The main controller 1 recognizes that the transmission has been received normally by detecting that the same information as the event area information that has been changed to the abnormality occurrence state is transmitted from the transceiver 2, and The response is made by changing the corresponding information to the non-occurrence state again.

  If the information of the event area that is changed to the abnormality occurrence state is not in the abnormality occurrence state in the next transmission from the transceiver 2, it is determined that the transceiver 2 has not received the information correctly, Respond again with the same information remaining in an abnormal state. Thereby, since transmission can be repeated until the transmitter / receiver 2 recognizes information, retransmission processing can be performed while maintaining the same communication sequence.

  Since the automatic notification device needs to monitor a wide variety of sensors in parallel, it may be necessary to transmit a plurality of abnormalities at the same time. By providing an event area, a plurality of pieces of abnormality information can be transmitted simultaneously while maintaining the same communication sequence, and retransmission management can be performed for each piece of abnormality information.

  In addition to the sensors that monitor only the occurrence of an abnormality, there are sensors that monitor that the abnormality continues, among the sensors that are monitored by the automatic notification device. Separately, a state area is provided, and the current state of the corresponding sensor is always reflected in each state area and transmitted from the main controller 1, so that the transmitter / receiver 2 side recognizes the occurrence of an abnormality from the event information and By monitoring the status area to be performed with each response, it is possible to manage the continuation state of the abnormality while maintaining the same communication sequence.

  FIG. 3 is a diagram illustrating an example of a single message format transmitted from the main control device 1. The message format used for the response in the main controller 1 includes a fixed-length event area 20, a main controller side event area 22 used for information transmission from the main controller to the transceiver, and a transceiver Two areas of a transmitter / receiver-side event area 23 used for confirmation of reception of information transmission to the main controller are included. Therefore, while maintaining the same communication sequence in the same message format, new information is transmitted from the main controller to the transceiver and reception confirmation of the information transmitted from the transceiver is performed simultaneously. It becomes possible by progress.

  FIG. 4 is a diagram illustrating an example of a single message format transmitted from the transceiver 2. The message format used for transmission from the transceiver 2 also includes the event area 32 on the main controller side used for confirmation of reception of information transmission from the main controller to the transceiver in the fixed-length event area 30; Two areas of a transmitter / receiver side event area 33 used for information transmission from the transmitter / receiver to the main controller are included. Therefore, while maintaining the same communication sequence in the same message format, it is possible to transmit new information from the transceiver to the main controller and to confirm reception of information transmitted from the main controller. It can be done simultaneously.

  The main controller side state area 24 in FIG. 3 and the transmitter / receiver side state area 34 in FIG. 4 are used to transmit information reflecting the current state in which each transmitting device does not require reception confirmation. By transmitting this state area each time at the same time as the event, it is possible to constantly monitor both states by the same communication sequence without requiring a special sequence for requesting the state.

  3 and 4, the leading codes 21 and 31, the final codes 25 and 35, and the error detections 26 and 36 are additional information for performing communication between the main controller 1 and the transceiver 2 without error. .

  FIG. 5 shows an example of a message layout that is commonly applied to the main control device side event area 22 and the main control device side event area 32 that is used to transmit abnormality information from the main control device 1 to the transceiver 2. FIG.

  When the main controller 1 detects an abnormality with the various sensors 11, the corresponding bit position in the main controller-side event area 22 is reversed (flag) in the response after receiving the next transmission from the transceiver 2. ) To inform the transceiver 2 that an abnormality has occurred.

  When the transmitter / receiver 2 receives the response from the main controller 1, the transmitter / receiver 2 determines the flag of the event area, notifies the receiving base unit 4 of the abnormality using the telephone line 102, and simultaneously transmits to the next main controller 1 In this transmission, the same bit position in the main control device side event area 32 is inverted (flag is turned on) to transmit to the main control device 1 that the abnormality information has been correctly received.

  In the next reception, when the transmitter / receiver 2 inverts (turns on the flag) the same bit position in the main control apparatus side event area 32 and transmits the same bit position as the information in which the bit position is inverted by itself last time, The transmitter / receiver 2 recognizes that the abnormal information has been successfully received, and in the next response, the bit position is inverted again (the flag is turned OFF) and the response is made.

  The transmitter / receiver 2 reverses the same bit position in the main control device side event area 32 (flag ON) in the next transmission to the main control device 1 when the report to the receiving base device 4 cannot be performed normally. Send without. Thus, main controller 1 recognizes that the abnormality information has not yet been transmitted, and repeats the response while reversing the corresponding bit position (flag is ON) in the next response.

  That is, the flag state of the corresponding bit position in the main control device side event area 32 in the next transmission from the transceiver 2 is the flag of the corresponding bit position in the main control device side event area 22 in the previous response from the main control device 1. If it is the same as the state, it indicates an affirmative response, and if it is not the same, it indicates a negative response.

  Should the transmitter / receiver 2 detect the same abnormality before the bit inversion (flag is turned on) in the main controller side event area 32 which means an affirmative response, the present invention is used. In the automatic notification device, which is a technical field, the number of times of the same abnormality that has occurred continuously is not important information, and is handled as one generation of information.

  In FIG. 1, the transmitter / receiver 2 performs the next transmission when reception is not received during T2 after transmission. If there is no transmission from the transmitter / receiver 2, information transmission from the main controller 1 is performed. Although it is due to the fact that it can not be done, even if the timing of transmission and reception crosses, because only one sequence is repeated, an acknowledgment or negative response can be returned in the next transmission and reception, so Even if a processing delay occurs in either the main controller 1 or the transmitter / receiver 2, the information transmission is delayed only for one round trip of transmission / reception, and it is not necessary to complicate the abnormality processing sequence. It is a feature.

  FIG. 6 is a diagram showing an example of a message layout applied to the main controller-side state area 24 used to transmit the current state of the various sensors 11 connected to the main controller 1 to the transceiver 2. is there.

  The main control device 1 responds by inverting the corresponding bit position in response to the transmission from the transceiver 2 every time, reflecting the latest state of the connected various sensors. After being notified of the occurrence of an abnormality in the main controller side event area 22, it is possible to monitor the recovery of the abnormality by monitoring the bit position of the main controller side state area 24 corresponding to the sensor. Become.

  If the transmitter / receiver 2 is highly functional, it is possible to construct a system only by transmitting / receiving state information without using a communication method such as that of the present invention. Inevitably, the development load and the high price of the transmitter / receiver alone are inevitable.

  On the other hand, in the communication method of the present invention, information is distinguished and arranged in the main control device side event area 22 and the main control device side state area 24, so that the most serious problem in the automatic notification device can be prevented. Therefore, it is possible to suppress the amount of information monitored by the transmitter / receiver 2 and to use the monitoring function of the main controller 1 that has been conventionally used as it is.

  Further, in general reception base device 4, only the occurrence of an abnormality is monitored, and there is often no particular monitoring regarding the recovery of the abnormality. Therefore, transmission / reception in the case of reception base device 4 that does not manage recovery is common. It is also easy to simplify the function of the machine 2.

  Conversely, an example of constructing a system in which the transmitter / receiver 2 always transmits all state information to the receiving base device 4 is generally found, but in this method, the monitoring target 101 is provided. When the quantity of various sensors 11 becomes very large, the amount of information transmitted / received through the telephone line 102 increases, which greatly affects the operational communication cost and at the same time increases the processing load on the receiving base apparatus 4. .

  On the other hand, in the communication method of the present invention, when the main controller side event area 22 and the main controller side state area 24 are separated, the transceiver 2 recognizes the information of the main controller side event area 22. Since only the reception base device 4 can be notified, the communication cost in the telephone line 102 and the processing load on the reception base device 4 can be reduced while simplifying the function of the transceiver 2.

  Furthermore, even when the same abnormality is detected in the automatic notification device, it is determined whether it is necessary to report as an abnormality depending on the alert state at the time of occurrence. In order to make the determination in the transmitter / receiver 2 unnecessary as usual, bit inversion is performed only in the case where it is necessary to report the abnormality to the main controller side event area 22, and the main controller side state area 24 It is effective to distinguish the two areas by reflecting the current state as is.

  Even when it is necessary to acquire the quantity information of various sensors deployed in the monitoring target store 101 at the receiving base 103, the various sensors are connected to the main control device side state area 24 shown in FIG. By defining to include presence / absence information, necessary information can be acquired.

  In addition, when the communication means of the telephone line 102 is changed, the transmitter / receiver 2 and the reception base device 4 must change each device, and it is necessary to define a communication method each time. It is also a feature of this communication system of the present invention that even if the communication system on the telephone line 102 changes, a communication system that can be used in common between the transceiver 2 and the main controller 1 is used.

  Furthermore, in the present invention, when information indicating that remote setting is desired is transmitted from the receiving base unit 4, the transmitter / receiver 2 sets the setting request information in the transmitter / receiver-side event area at the next transmission of transmission to the main controller 1. Communicate the request by sending it including

  The main controller 1 informs that the request has been received normally by responding by including the same content as the setting request information included in the event area on the transmitter / receiver side in the response message, and during the subsequent setting processing, In response to the transmission performed immediately after the completion of the setting process while exchanging messages with the transceiver, information indicating that the setting has been completed is included in the event area on the main controller 1 side. By making a response, it is possible to notify the transceiver of the completion of setting while maintaining the same communication sequence.

  If a reception confirmation response cannot be obtained in response to the setting request, the transmitter / receiver 2 continues the same communication sequence and performs retransmission processing, and stores information indicating the setting request until a reception confirmation response is obtained. Keep sending.

  On the contrary, even if the main controller 1 makes a response notifying the completion of setting, even if the transmitter / receiver 2 does not perform transmission that means reception confirmation in the next transmission, the main controller 1 does not receive reception confirmation until The same communication sequence is continued and retransmission is performed.

  In the event information from the main control device 1 that notifies the completion of setting, in addition to the normal completion of setting, a format of information indicating abnormal completion is also defined. Accordingly, it is possible to recognize that the setting has not been normally performed on the transmitter / receiver 2 side and perform the setting again while maintaining the same communication sequence.

  FIG. 7 shows an example of a message layout that is commonly used for the transmitter / receiver-side event area 33 and the transmitter / receiver-side event area 23 and is used to transmit automatic operation setting information from the transmitter / receiver 2 to the main controller 1. FIG.

  When the operation information is changed remotely at the receiving base device 4, when the transceiver 2 receives the setting request information transmitted via the telephone line 102, the transceiver 2 is included in the transceiver-side event area 33. At the same time, the bit position indicating that the switching station time to be updated is reversed (the flag is turned on), and at the same time, the bit position indicating the request date information and the bit position indicating the request switching station time information included in the transmitter-side event area 33 Then, bit inversion indicating the numerical information of the requested content is performed, and transmission to the main controller 1 is performed next time.

  When the main controller 1 recognizes the bit inversion in the event area 33 on the transmitter / receiver side in the message received from the transmitter / receiver 2, the main controller 1 decodes the requested date information and switching station time information to the next transmitter / receiver 2. In the response message, the request bit is acknowledged by responding with the same bit position of the transmitter / receiver-side event area 23 reversed (flag ON).

  The main control device 1 changes the setting after giving an affirmative response. When the setting change is completed normally, the main control device 1 is defined in the main control device-side event area 22 in the response to the next transmission from the transceiver 2. The transmitter / receiver 2 is notified that the setting has been normally completed by responding by reversing the flag position indicating the normal completion of the setting (turning on the flag). The transmitter / receiver 2 that has recognized the notification notifies the receiving base unit 4 of the notification result, and at the same time, transmits to the main control unit side event area 32 by performing bit inversion indicating an affirmative response in communication with the main control unit 1. Do.

  In general, setting changes involve rewriting the memory, etc., and it often takes time to process. Therefore, from returning an acknowledgment indicating that the request has been received until returning a response indicating that the setting has been completed successfully In the meantime, the communication sequence between the transceiver 2 and the main controller 1 is repeatedly transmitted and received as usual, and the main controller 1 performs various processes simultaneously during the setting process. It is a feature of the present invention that notification can be made when an abnormality of the sensors is detected.

  In the case where the setting change has not been completed normally (abnormally completed), in the response from the main controller 1 to the transmitter / receiver 2, the flag position indicating completion of setting abnormality defined in the main controller side event area 22 is set. Inverts (flag is turned on) and responds. That is, in addition to the transmitter / receiver side event areas 23 and 33 shown in FIG. 7, two bit positions indicating normal setting completion and abnormal setting completion are defined in the main controller side event area 22 and the completion notification is correctly received. In order to respond to this, a similar bit position is defined in the event area 32 on the main controller side.

  Further, in the present invention, when a reference request is made from the transmitter / receiver 2 for the setting result of the automatic operation, event information indicating a reference answer from the main control device 1 is included in the main control device side event area and transmitted / received at the same time. The setting content area in the machine-side event area is sent including the setting completion information.

  In order to notify the contents of the setting information of automatic operation from the main controller 1 to the transceiver 2, the transceiver-side event areas 23 and 33 are used. That is, the transceiver 2 that has received the reference request information transmitted from the reception base device 4 when the operation for referring to the setting contents of the monitoring target store 101 or the like is performed at the reception base 103 is the transmitter-side event area 33. The bit position indicating the reference request in FIG. 7 included in FIG. 7 is reversed (the flag is turned on), and at the same time, the bit position indicating the date information in FIG. Next, transmission to the main controller 1 is performed.

  The main control device 1 recognizes the reference request and gives an affirmative response by inverting the same bit position in the transmitter / receiver-side event area 23 (the flag is turned on) in the next response, and thereafter the setting information stored in the memory And the bit position indicating the reference response defined in the main controller side event area 22 is inverted (flag is turned on) at the next response timing to indicate that the response is notified, and at the same time, the transceiver Using the time information area of FIG. 7 included in the side event area 23, the switching station time of the requested date is notified.

  In general, the data for transmitting / receiving the setting information includes a lot of information in addition to the layout example shown in FIG. 7, so that the message length increases as the function of the main control device 1 increases. When the communication speed with the control device 1 is low, it can be a fatal problem. However, since the information for making a setting request from the receiving base 103 and the information for making a reference request are almost the same, It is a feature of the present invention that the message length is reduced to about half by realizing the reference with the same layout.

  Furthermore, in the present invention, when information to be remotely controlled is transmitted from the receiving base unit 4, the transmitter / receiver 2 transmits the control request information in the transmitter / receiver side event area at the next transmission to the main control unit 1. Communicate the request.

  The main control device 1 informs that the request has been received normally by responding with the same content as the control request information included in the transmitter / receiver-side event area at the time of response, and then the state of the controlled device has changed The transmitter / receiver 2 can recognize this by changing the information in the state area. In this way, control processing and information transmission of control results can be performed while maintaining the same sequence.

  FIG. 8 is a diagram showing an example of a message layout that is commonly applied to the transmitter / receiver-side event area 33 and the transmitter / receiver-side event area 23 and is used to transmit remote control information from the transmitter / receiver 2 to the main controller 1. It is.

  When controlling the various equipment devices 12 connected to the main control device 1 remotely from the reception base device 4, when the transceiver 2 receives control request information transmitted via the telephone line 102, the transceiver 2 Inverts the bit position indicating the corresponding control request in FIG. 8 included in the transmitter / receiver event area 33 (flag is turned on), and performs transmission to the main controller 1 next time.

  When the main control device 1 recognizes the bit inversion included in the transmitter / receiver side event area 33 of the message received from the transmitter / receiver 2, it will be included in the transmitter / receiver side event area 23 in the next response message to the transmitter / receiver 2. The response to the request is made by reversing the same bit position (turning the flag ON) and performing a response.

  After the main controller 1 performs an affirmative response, it performs control on the requested various equipment 12 and the result of the control is the status information of the corresponding equipment defined in the main controller-side status area 24. Subsequent communication between the transmitter / receiver 2 and the main control device 1 is surely notified.

  In general, in the control of equipment, not only can the state be expressed by only two values, normal completion and abnormal completion, but, for example, in the case of a shutter, the state changes to a rising state after receiving a request for an increase. Since the operation is such that the upper limit is reached after the ascending over time and the operation stops, there are many cases where it is necessary for the receiving base 103 to recognize the state of the way and the content of the abnormality. Therefore, it is also a feature of the present invention that more detailed information transmission is possible by subdividing a state requiring information acquisition and defining it in the main control device side state area 24.

  In communication between the receiving base apparatus 4 and the transceiver 2, after making a control request from the receiving base apparatus 4, the state of the corresponding equipment is repeatedly acquired from the transceiver 2 only during a period in which state monitoring is necessary. By controlling, it is possible to acquire necessary information while minimizing communication using the telephone line 102.

  Further, in the present invention, an area dedicated to the ID number is provided in the event information area from the main control device 1 side, and indicates that switching has been performed during the warning state switching operation performed on the main control device 1 side. Together with the event information, the switched ID information is sent at the time of the next response in communication with the transceiver 2. As a result, the main control device 1 side can transmit the information on the operator side that the switching operation has been reliably performed to the transceiver 2 while maintaining the same sequence.

  FIG. 9 is common to the main control device side event area 22 and the main control device side event area 32, which is used to transmit the warning state switching operation from the main control device 1 to the transceiver 2. It is a figure which shows the example of the message | telegram layout applied.

  When the alert state is switched in the monitoring target store 101 or the like, the main control device 1 responds to the communication from the next transmitter / receiver 2 with the alert set included in the main control device side event area 22 or the alert release. At the same time, the bit position of ID information for identifying the person who performed the operation included in the main device side event area 22 is reversed so as to indicate the numerical information. Make a response.

  When the transmitter / receiver 2 recognizes the bit inversion (flag is ON) of the main control device side event area 22 received from the main control device 1, it simultaneously notifies the receiving base device 4 including the ID information transmitted at the same time. After the notification is completed, the same bit position in the main control device side event area 32 is inverted (the flag is turned on) in the next transmission to the main control device 1 to transmit an affirmative response to the alert state switching information notification. Do.

  Generally, since it is necessary to always recognize the alert state of the monitored store 101 or the like at the receiving base 103, if the alert is set and canceled continuously, the final switching direction is notified. There is a need.

  However, since there is a risk of generating the illusion that the recognition of the previous warning state is wrong if notification is made as if switching to the same warning state is performed, a plurality of switching operations are performed as shown in FIG. Are prepared separately from the bit positions meaning each switching operation. In this way, since the execution of a plurality of switching operations and the final switching direction are notified, it is also a feature of the present invention that the above-described problems can be avoided. In order to further improve the accuracy of information, it is also possible to define a bit position indicating the current alert state in the main control device side state area 24 as well.

  In the communication method described above, the transmission / reception device 2 always transmits to the main control device 1 and receives the response, but the transmission / reception device 2 repeats the main operation repeatedly during a certain period. When a response is not returned even if transmission to the control device 1 is performed, it is possible to prevent in advance a situation where monitoring cannot be continued by reporting to the receiving base device 4 as an abnormality of the main control device 1, Further, by periodically checking the communication state between the transmitter / receiver 2 and the receiving base device 4, it is possible to cope with the failure of the transmitter / receiver 2.

  In the case where it is necessary to record the occurrence of an abnormality as a history in the main control device 1 separately from the monitoring at the receiving base 103 or to notify the operator of the monitored store 101 or the like of the occurrence of the abnormality. By defining a bit position indicating abnormality information on the transmitter / receiver 2 side in the transmitter / receiver state area 34 in FIG. 4, the main controller 1 can also recognize the abnormality of the transmitter / receiver 2.

  The communication method of the automatic notification device according to the present invention is a new public line that requires only minor software changes in the expandable communication unit to support this communication method while continuing to use the automatic notification device that has been conventionally used. It is possible to prepare an inexpensive transmitter / receiver that can be used as a communication means, and it is possible to cope with the latest communication means, and it is possible to suppress capital investment, and criminal acts such as stores and houses This is useful as a communication method for an automatic reporting device that monitors the occurrence of abnormalities related to equipment and reports to a predetermined reporting destination via a telephone line.
