The warning lamp 700 and the siren 417 are driven by the control of the main control circuit 401 when it is determined that the warning state 700 and the siren 417 are abnormal.

The operation of the present invention having such a configuration will be described below with reference to FIGS. 4 to 7.

The automatic reporting device 400a of the primary subscriber connected to the leased line 800 manages the automatic reporting device 400 of the auxiliary subscribers adjacent to the predetermined area.

First, referring to FIG. 5, the operation of the automatic reporting device installed in the primary subscriber will be described. The automatic reporting device 400a of the primary subscriber calls any one of the automatic reporting device 400 of the secondary subscriber (S1). Here, the call between the automatic reporting device 400, 400a is made through the wireless transmitter / receiver 405 and the antenna 600, and each automatic reporting device 400, 400a has a format as shown in FIG. Send / receive protocol.

That is, the primary subscriber's automatic reporting device 400a stores all of the secondary subscriber's identification codes in the primary control circuit 401, and as shown in FIG. 4 (b), the primary subscriber's automatic reporting device 400a. ) Sequentially detects the identification code of the subsidiary subscriber and calls the subsidiary subscriber, waits for a certain time, and the subsidiary subscriber's automatic reporting device 400 responds to the call signal called by the primary subscriber's automatic reporting device 400a. Transmit a response signal. At this time, the response signal as shown in Figure 4a, 'START' indicating the start of the protocol, the 'identification code of the secondary subscriber' and 'subscriber status' and the automatic reporting device installed in the adjacent secondary subscriber ( In case of abnormal operation, it consists of 'received data' stored in another adjacent or primary subscriber, 'CHECK' of a checksum function for error correction, and 'END' indicating an end state. At this time, when the automatic reporting device (400, 400a) of the secondary subscriber or the primary subscriber is in the alarm generation mode (when an emergency situation is detected), data indicating the emergency situation is displayed in the area where the subscriber status information is displayed in the protocol of FIG. 4a. In addition, the location information of the subscriber is included.

The primary subscriber's automatic reporting device 400a checks whether a response signal is transmitted from the secondary subscriber's automatic reporting device 400 (S2), and when the response signal is received from the secondary subscriber, the secondary subscriber included in the received response signal is received. Register the operation state of the installed automatic reporting device 400 in the data memory (S3), if the response signal is not received from the secondary subscriber, after performing the recall process a predetermined number of times (S4), the recall operation is a predetermined number When exceeding, it is determined that an abnormality has occurred in the automatic signal device 400 of the auxiliary subscriber and registers it in the data memory (S5).

Subsequently, the automatic notification device 400a of the primary subscriber sends a confirmation signal (i.e., 'CHECK') to the secondary subscriber (S4), and then detects the identification code of the next secondary subscriber (S7), up to the last secondary subscriber. Steps S1 to S7 are repeated (S8).

When the confirmation of the operation status of the automatic reporting device 400 until the last subsidiary subscriber is finished, the automatic reporting device 400a of the primary subscriber operates the dedicated line circuit 408 so that the automatic reporting device 400a and the dedicated line of the primary subscriber are available. After connection (800) (S9), and transmits the operation state information of each subscriber stored in the data memory to the central control room (S10).

Subsequently, the main subscriber's automatic reporting device 400a checks whether a confirmation signal is received from the central control room (S11), and when the confirmation signal is received, returns to the above step (S1) to perform all the processes after the step (S1). Repeat it. If the confirmation signal is not received from the central control room in this step (S11), the automatic notification device 400a of the main subscriber checks the state of the dedicated line 800 (S12), and the dedicated line 800 is checked. If it is determined that the steady state is transmitted repeatedly the operation state information of each subscriber for a predetermined number of times (S13). In addition, as a result of checking in step S12, it is determined that the dedicated line 800 is in an abnormal state (a state in which communication with the central control room cannot be performed) or the state of each subscriber is set for a predetermined number of times set in step S13. If the confirmation signal is not received in the central control room despite the retransmission, the main control circuit 401 in the automatic notification device 400a of the main subscriber supplies the switching relay 407 with the operation signal, and the switching relay 407 The general telephone line 500 is connected to the telephone circuit 406 in response to the operation signal supplied from the main control circuit 401. Accordingly, the main subscriber's automatic reporting device 400a connects the general telephone line 500 to transmit the status of each subscriber, and the dedicated line 800 connected to the main subscriber's automatic reporting device 400a. Transmit abnormal status of.

Thereafter, the main subscriber's automatic reporting device 400a checks whether a confirmation signal is received from the central control room (S15), and when the confirmation signal is received from the central control room, returns to the above step (S1) and after step S1. Repeat the entire process of, and if the confirmation signal is not received from the central control room transmitted through the wireless transmitter / receiver 405 to the automatic notification device 400 that can operate normally of the automatic reporting device 400 of the adjacent subsidiary subscribers. After transmitting the impossible signal (S16), it is checked whether an acknowledgment signal is received from the automatic reporting device 400 of the auxiliary subscriber (S17).

If the acknowledgment signal is not received at this step (S17), the main subscriber's automatic reporting device 400a returns to step S16 above and transmits a transmission impossible signal to the next subsidiary's automatic reporting device 400. After the acknowledgment signal is received, the automatic notification device 400 of the remaining auxiliary subscribers is polled sequentially.

If the acknowledgment signal is received from the secondary subscriber's automatic reporting device 400 in this step (S17), the primary subscriber's automatic reporting device 400a is informed of its abnormal status and the other secondary subscribers stored up to now. After transmitting all the information on the operation state (S18), and confirms whether the corresponding information was transmitted from the automatic notification device 400 of the secondary subscriber to the central control room, and returns to the above step (S1).

Therefore, the automatic notification device 400a of the primary subscriber can automatically report the primary and secondary subscribers even if only one device of the dedicated line 800, the general telephone line 500, and the wireless transmitter / receiver 405 is available. The operation status of the devices 400a and 400 can be notified to the central control room, and the central control room can check the operation status of the automatic reporting devices 400a and 400 of each subscriber from time to time.

On the other hand, with reference to Figure 6 will be described the operation of the automatic reporting device 400 installed in the secondary subscriber.

First, the auxiliary subscriber's automatic reporting device 400 uses a wireless transmitter / receiver 405 to communicate with the primary subscriber's automatic reporting device 400a and the protocols shown in FIGS. 4 (a) and 4 (b). Send / receive data according to At this time, the automatic reporting device 400a of the primary subscriber and the automatic reporting device 400 of the secondary subscriber are operated in synchronization with a predetermined condition.

The secondary subscriber's automatic reporting device 400 checks whether there is a call from the primary subscriber's automatic reporting device 400a (S20), and if there is no call, detects each of the sensors 409a to 409c, 410a to 410c, and 411a to 411c. The result detected from the circuits 412 to 414 is checked to determine whether it is in an alarm state (S21). If it is determined that the alarm state is detected, the mode is switched to the alarm generation mode described later with reference to FIG.

If it is determined in step S20 that the call signal is received from the primary subscriber's automatic report device 400a, the secondary subscriber's automatic report device 400 determines whether the corresponding call signal is a polling signal or a relay request signal. It is determined (S23).

If it is determined in this step (S23) that the polling signal, the secondary subscriber's automatic reporting device 400 transmits the status information on whether the abnormality to the primary subscriber's automatic reporting device (400a) (S24), the confirmation signal for this Check whether it is received (S25). When the confirmation signal is received in this step (S25), the automatic notification device 400 of the secondary subscriber returns to the above step (S20) to repeat the process after the step (S20).

If the confirmation signal is not received even if the preset time is exceeded in this step (S25) (S26), it means that a momentary communication failure occurs in the wireless transmitter / receiver 405 of the corresponding subsidiary subscriber. ) To connect the general telephone line 500 to the telephone circuit 406 (S27). Here, the automatic reporting device 400 of the auxiliary subscriber checks the state of the general telephone line 500 (S28), and if the general telephone line 500 is in a normal state, dialing the central control room through the telephone circuit 406 ( S29), status information related to the abnormality is directly transmitted to the central control room (S30), and it is checked whether a confirmation signal is received from the central control room (S31). When the confirmation signal is received in this step (S31), the automatic reporting device 400 of the secondary subscriber returns to the above step (S20) and repeats all the steps after the step (S20), if the confirmation signal is not received, the setting It waits until it exceeds time (S32), and calls another auxiliary subscriber using the wireless transmitter / receiver 405 of the said auxiliary subscriber (S33). When the reception of the relay signal from the other subsidiary subscriber is confirmed in this step (S33) (S34), the subsidiary subscriber's automatic reporting device 400 whether the subsidiary subscriber's abnormality to the other subsidiary subscriber's automatic reporting device 400 Transmitting the status information indicating (S35), and relays the corresponding status information through the automatic reporting device 400 of the other subsidiary subscriber connected (S36). Thereafter, when the transmission completion confirmation signal is received from the automatic reporting device 400 of the other subsidiary subscriber, the automatic reporting device 400 of the subsidiary subscriber returns to the above step S20 to perform all processes after the step S20. Repeat it.

On the other hand, if it is determined in the above step (S23) that the call state from the primary subscriber's automatic reporting device 400a is a relay request state, the secondary subscriber's automatic reporting device 400 of the primary subscriber with the dedicated line 800 is installed. After checking whether an abnormality has occurred in the automatic reporting device 400a (S38), after switching to the relay mode for relaying the automatic reporting device 400a of the main subscriber (S39), the process returns to step S27 (S27) All the subsequent steps are repeated.

In addition, if it is determined in step S38 above that the automatic reporting device 400a of the primary subscriber in which the dedicated line 800 is installed is not in an abnormal state, the automatic reporting device 400 of the auxiliary subscriber is a relay request of another auxiliary subscriber. If it is determined (S40), if it is determined that the relay request of the other subsidiary subscriber, the relay information indicating the abnormal state for the automatic notification device 400 of the other subsidiary subscriber in the status information on the automatic reporting device of the subsidiary subscriber After including the signal (S41), and returns to the above step (S24) to repeat all the steps after the step (S24).

Therefore, even if an error occurs in the automatic reporting device 400 of another auxiliary subscriber, the central control room indicates that an error occurred in the automatic reporting device 400 of another auxiliary subscriber by the relay of the automatic reporting device 400 of the auxiliary subscriber. Can be notified.

Lastly, referring to FIG. 7, a description will be given of a process of notifying the central control room when an alarm occurs.

When the siren 417 and the warning light 700 is operated in the alarm generation mode (S22) (S42), the corresponding automatic reporting device (400a, 400) checks whether the dedicated line 800 is connected (S43), dedicated If the line 800 is connected, the automatic reporting device (400a, 400) is recognized as the automatic notification device (400a) of the main subscriber, and then control the dedicated line circuit 408, the automatic reporting device (400a) of the main subscriber After connecting to the dedicated line 800 (S44), and transmits the status information indicating that the alarm occurred to the main subscriber to the central control room (S45). At this time, the status information includes the information on the alarm occurrence, the identification code of the subscriber and the location information of the subscriber, the location information, it is preferable to use the general GPS (Global Positioning System) location information Do. Thereafter, it is checked whether an acknowledgment signal indicating that the corresponding state information is received from the central control room is received (S46). When the acknowledgment signal is received, the automatic notification device 400a of the main subscriber finishes transmitting the state information, and the siren 417 ) And the warning light 700 is recovered after the control personnel (1000) check the automatic reporting device (400a) while maintaining the operation state so that the control personnel (1000) arrive at the site and easily find the place where the alarm occurs. If the function is selected (S47), after waiting to recover to the normal state (S48).

If the confirmation signal is not received from the central control room in the above step (S46), repeatedly transmits a predetermined number of times (S49), and if the confirmation signal is not received until the predetermined number of times is exceeded, the wireless transmitter / receiver 405 By notifying the abnormal state of the dedicated line 800 to the automatic notification device 400 of the secondary subscriber (S50), and controlling the switching relay 407 using the primary subscriber's automatic reporting device (400a) and general After the telephone line 500 is connected, the telephone circuit 406 is controlled to open the general telephone line 500 (S51). When the general telephone line 500 is opened, the automatic notification device 400a of the main subscriber controls the telephone circuit 406, dials the central control room (S52), and includes the identification code and location information of the main subscriber. The information is transmitted (S53). After that, the automatic notification device 400a of the main subscriber checks whether the confirmation signal is received from the central control room (S54), and when the confirmation signal is received, checks whether the connection is made by the general telephone line 500 (S55). If the connection by the telephone line 500, the telephone circuit 406 is controlled to cut off the general telephone line 500 (S56), and then returns to the above step (S47) to repeat all the processes after the step (S47). If it is not connected by the general telephone line 500, the operation of the wireless transmitter / receiver 405 is blocked (S57).

If the confirmation signal is not received from the central control room until the waiting time is exceeded in the above step (S54) (S58), the main subscriber's automatic reporting device 400a is adjacent to each other using the wireless transmitter / receiver 405. After requesting the relay by transmitting the status information including the abnormal status of the primary subscriber's automatic reporting device 400a and the identification code and the location information to the auxiliary subscriber's automatic reporting device 400 (S59), the process returns to step S54. By repeating all the steps after step S54.

On the other hand, if the dedicated line 800 is not installed in the above step (S43), this indicates that the automatic notification device 400 of the secondary subscriber, as shown in Figure 4 (c), the secondary subscriber The automatic reporting device 400 transmits an alarm occurrence state to the automatic subscriber device 400a of the primary subscriber by using the wireless transmitter / receiver 405 (S60), and confirms the receipt from the automatic subscriber device 400a of the primary subscriber. It is checked whether a signal is received (S61). When the acknowledgment signal is received in this step (S61), the automatic notification device 400 of the secondary subscriber proceeds to step S59 and repeats all the processes after step S59.

If the acknowledgment signal is not received from the primary subscriber's automatic reporting device 400a in this step (S61), the automatic subscriber's automatic reporting device 400 of the secondary subscriber receives a predetermined number of abnormal states through the wireless transmitter / receiver 405. If the acknowledgment signal is not received until the number of transmissions exceeds the predetermined number of times after repeating the transmission (S62), the process proceeds to step S51 to notify the central control room via the general telephone line 500.

Therefore, the automatic reporting device 400a of the primary subscriber and the automatic reporting device 400 of the plurality of auxiliary subscribers adjacent to the predetermined area are configured in a system form, thereby increasing the reliability of the alarm notification.

At this time, the radio transmitter / receiver 405 transmits / receives data by performing a multi-channel communication in a frequency band that is permitted to be used without a separate radio station license, such as a known 900 [MHz] radio telephone. The reception can be operated stably and economically.

As described above, although the specific embodiment (s) have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiment (s), but should be defined by the claims below and equivalents thereof.

As a result, the automatic reporting system according to the present invention has the following advantage (s).

That is, a single main subscriber integrates and manages a number of auxiliary subscribers located in a certain area by using a wireless transmitter / receiver that performs multi-channel communication using a general-purpose frequency band, and the central control room through a dedicated line connected to the main subscriber. By transmitting the signal to the subscriber, it is possible to achieve the same effect as the state in which all the dedicated lines are connected without connecting the dedicated lines to each subscriber, so that the system can be operated very economically.

In addition, even if the communication line is artificially cut off from the outside without using an expensive wireless data modem, a signal is transmitted to the automatic reporting device of another subscriber adjacent to the wireless transmitter / receiver, thereby safely reporting. Safe and reliable.

In addition, in a device using a wireless data modem, if there is radio interference, it is impossible to use, but in the present invention, since the signal is automatically switched to a general telephone line to transmit a signal, the safety report is made in any case and the reliability is improved.

In addition to the subscriber identification code, the subscriber's location information measured by the GPS receiver in the subscriber's location is stored in the automatic reporting device, and at the time of an alarm or an abnormal condition, an abnormal state or alarm occurrence state information including an identification code and location information. If you send a message, the central control room transmits the subscriber identification code and location information to the dispatching vehicle, and the dispatching vehicle can be dispatched after recognizing the exact location and distance using an electronic map stored in its GPS receiver or portable computer. It is possible to dispatch to the site quickly and accurately, and in the central control room, the control computer program can automatically order the dispatching vehicle to the nearest location, so that the dispatching service is carried out at the lowest cost.
