By not receiving the signal within the predetermined time, it is identified that the transmission of the reply signal to the wireless device (C) 14 has failed, and the reply route information “54 × 53” indicating the route of the reply signal up to now is identified.

Then, the radio (D) 15 sets the radio (F) 17 having the telephone number “56” as the transfer destination radio based on the transfer route information “54-56” indicating the bypass route. The determined reply route information “54 × 53” is added to the determined wireless device (F) 17 determined as the transfer destination, and a reply signal is transmitted.

Upon receiving the return signal from the wireless device (D) 15, the wireless device (F) 17 returns the return route information “54 × 53-56” indicating the success / failure of the transfer route of the return signal so far.

Then, the wireless device (F) 17 determines the wireless device (E) 16 having the telephone number “55” as the transfer destination wireless device based on the transfer path information “55-56”, and determines the transfer destination. A reply signal is transmitted with the identified return route information “54 × 53-56” added to the wireless device (E) 16.

Then, thereafter, the wireless device (E) 16 and the wireless device (B) 13 execute the same processing as described above, and the wireless device (A) 12 returns a response from the wireless device (B) 13. When the signal is received, return route information “54 × 53-56-55-52-51” indicating the transfer route of the return signal so far is identified. Then, the terminal 24 transmits the reply route information “54 × 53−” added to the reply signal received by the wireless device (A) 12.
56-55-52-51 ". In this case, since" 52.times.53 "indicating a route failure exists, it is identified that some trouble has occurred in the system.

As described above, in the terminal 24, if the reply signal indicates the return route information indicating the return route in which the pass / fail has actually passed, if the information indicating the pass failure does not exist, the system returns. It is possible to identify that the system is normal without any failures, while it is possible to identify that there is some failure in the system if there is information indicating the route failure. It becomes possible. In this case, since “54 × 53” exists in the reply route information, the wireless device (C) 14 having the telephone number “53” or the vicinity of the wireless device (C) 14 It is possible to specify that this is the location where the error occurred.

Now, in the configuration described above, each radio, when receiving a transmission signal, identifies an index indicating a communication state with another radio which transmitted the transmission signal, and transmits transmission route information. At the same time, it is also possible to transmit an index indicating the identified communication state.

That is, taking the case where the reception electric field level is adopted as an index indicating the communication state as an example with reference to FIG. 12, the radio equipment (B) 13 transmits a transmission signal from the radio equipment (A) 12. Upon reception, the transmission route information “51-52” indicating the transfer path of the transmission signal so far is identified, and the reception electric field level of the received transmission signal is identified (in FIG. 12, the reception electric field level is, for example, “50 dBμ”).
Is shown). Then, the wireless device (B) 13 sends the identified transmission route information “51-52” and the received electric field level “50 dBμ” to the wireless device (C) 14 determined as the transfer destination.
Is added and the transmission signal is transmitted. Thereafter, each wireless device performs the same processing.

Further, not only when receiving a transmission signal but also when receiving a reply signal, each wireless device identifies an index indicating a communication state with another wireless device which has transmitted the reply signal. It is also possible to transmit an index indicating the identified communication state together with the reply route information.

That is, a case where the reception electric field level is employed as an index indicating the communication state will be described with reference to FIG. 13, for example. The radio (C) 14 transmits a reply signal from the radio (D) 15 Upon reception, the reply route information “54-53” indicating the transfer path of the reply signal up to now is identified, and the received electric field level of the received reply signal is identified (in FIG. 13, the received electric field level is, for example, “45 dBμ”).
Is shown). Then, the wireless device (C) 14 sends the identified return route information “54-53” and the received electric field level “45 dBμ” to the wireless device (B) 13 determined as the transfer destination.
And sends a reply signal. Also in this case, thereafter, each wireless device executes the same processing.

In the configuration described above, each wireless device transmits, as a transmission signal, a signal requesting a status report to another wireless device or a terminal connected to the other wireless device. Alternatively, a signal reporting the status of the terminal itself or a terminal connected thereto can be transmitted as a reply signal.

Each wireless device transmits, as a transmission signal, a signal instructing various settings to another wireless device or a terminal connected to the other wireless device, and, as a reply signal, transmits a signal to itself or a self-terminal. It is also possible to transmit a signal reporting that various settings of the terminal connected to itself have been completed.

Each wireless device transmits, as a transmission signal, a signal indicating various data to another wireless device or a terminal connected to the other wireless device, and returns a signal as a reply signal.
It is also possible for the terminal itself or the terminal connected thereto to transmit a signal reporting that the reception of the signal indicating the data has been completed.

Further, in the configuration described above, instead of the terminal 24, the radio (A) connecting the terminal 24
12 compares the regular transmission route information with the transmission route information, compares the regular return route information with the return route information, identifies the transmission route information, or identifies the return route information, thereby It is also possible to identify that some trouble has occurred.

Now, the above description is from the wireless device (A) 12 to the wireless device
(B) 13 and the radio (C) 14 are relayed to the radio (D) 1
5 and transmits a transmission signal to the radio (D) 15 in response to the transmission signal.
From the wireless device (C) 14 and the wireless device (B) 13 to transmit a reply signal to the wireless device (A) 12, that is, the wireless device (A) 12 acts as a transmitting wireless device, (B) 13
And the radio (C) 14 operates as a relay radio, and the radio (D) 15 operates as a reply radio. Next, the radio (D) 15 transmits the radio ( C) 1
When transmitting a transmission signal to the wireless device (A) 12 via the wireless device (B) 13 and the wireless device (B) 13, the wireless device (D) 15 acts as a transmitting wireless device, and the wireless device (C) 14 and the wireless device (C) Machine (B)
The case where the radio 13 operates as a relay radio and the radio (A) 12 operates as a reception radio will be described.

In this case, the radio device (A) 12 can specify the location where the failure has occurred even if a failure has occurred in the system by the following two methods.

(5) By comparing the regular transmission route information indicating the regular transmission route that the transmission signal should pass through based on the transmission route information with the transmission route information indicating the transmission route that the transmission signal actually passed. (6) A system status is identified by identifying transmission route information indicating a transmission route through which a transmission signal has actually passed / failed. Method (corresponding to claim 13 of the present invention) Hereinafter, each of these (5) and (6) will be sequentially described.

(5) By comparing the normal transmission route information indicating the normal transmission route that the transmission signal should pass through based on the transfer route information with the transmission route information indicating the transmission route that the transmission signal actually passed. In this case, as shown in FIG. 14 and FIG. 15, when compared with those described in FIG. 8 and FIG.
(A) 12 is the same as the process executed after the transmission signal is transmitted to the wireless device (D) 15 by relaying the wireless device (B) 13 and the wireless device (C) 14, that is, the wireless device ( D) 15 is
Radio (C) 14 and radio (B) 13
(A) Instead of transmitting a reply signal to 12, a transmission signal is transmitted.

The terminal 24 compares the regular transmission route information with the transmission route information instead of comparing the regular reply route information with the return route information. , It is possible to identify that the system is normal without any trouble, and if the two are different, it is possible to identify that some trouble has occurred in the system.

(6) Method of Identifying System Status by Identifying Transmission Route Information Indicating Transmission Routes in Which Transmission Signals Successfully Passed / Failed In this case, as shown in FIG. Compared to the one described in 11, the wireless device (A) 12
(B) 13 and the radio (C) 14 are relayed to the radio (D) 1
5 is performed after the transmission signal is transmitted, that is, the wireless device (D) 15 relays the wireless device (C) 14 and the wireless device (B) 13 to relay the wireless device (A). In place of sending the reply signal to S12, a send signal is sent.

The terminal 24 identifies the transmission route information instead of the return route information. If there is no information indicating the route failure, the terminal 24 does not have any trouble in the system. It is possible to identify that the system is normal, while it is possible to identify that some trouble has occurred in the system if there is information indicating the route failure.

In these cases as well, as shown in FIG. 17, when receiving a transmission signal, each radio transmits an index indicating a communication state with another radio transmitting the transmission signal. It is also possible to transmit an index indicating the identified communication state together with the transmission route information.

In the configuration described above, each wireless device can transmit, as a transmission signal, a signal reporting the status of itself or a terminal connected thereto. Each wireless device can also transmit, as a transmission signal, a signal reporting that various settings of itself or a terminal connected thereto have been completed.

Further, in the above-described configuration, the radio (A) connecting the terminal 24 instead of the terminal 24
By comparing the regular transmission route information with the transmission route information or by identifying the transmission route information, it is also possible to identify whether or not any trouble has occurred in the system.

As described above, according to this embodiment,
Radio (A) 12 to Radio (B) 13 and Radio (C) 1
4 and transmits a transmission signal to the wireless device (D) 15. In response to this, the wireless device (D) 15 relays the wireless device (C) 14 and the wireless device (B) 13 to transmit the wireless signal ( In the configuration in which the reply signal is transmitted to A) 12, in the terminal 24 connected to the wireless device (A) 12, the regular transmission route information indicating the regular transmission route through which the transmission signal should pass, and the transmission signal The system status is identified by comparing with transmission route information indicating a transmission route that has passed.

Therefore, if a problem occurs in the system, the transmission signal passes through a transmission route different from the regular transmission route to be transmitted due to the trouble, and the transmission signal includes the normal transmission route information. Since the transmission route information is different, the terminal 24 identifies that the two are different from each other, so that it is possible to identify that some trouble has occurred in the system. In this case, it is possible to identify the location where the failure has occurred.

In the terminal 24, regular reply route information indicating a normal reply route through which the reply signal should pass,
The system is configured so as to identify the status of the system by comparing the reply signal with reply route information indicating the reply route actually passed.

Therefore, if any trouble occurs in the system, the reply signal passes through a reply route different from the regular reply route to be passed due to the trouble, and the regular reply route information and Since the reply route information is different, the terminal 24 can identify that the two are different, thereby identifying that some trouble has occurred in the system. In this case, it is possible to identify the location where the failure has occurred.

In this case, if the regular transmission route information and the transmission route information are compared with each other and then the regular reply route information and the reply route information are compared with each other, it is possible to specify a location where a problem has occurred. Therefore, the accuracy can be improved, and the location where the failure has occurred can be specified more accurately.

In the terminal 24, the system status is identified by identifying the transmission route information indicating the transmission route in which the transmission signal has actually passed / failed.

Therefore, if any trouble occurs in the system, the transmission signal fails to pass through the normal transmission route through which the transmission signal should pass, and the transmission signal should pass through the terminal 24. By identifying that the route has failed in the legitimate transmission route, it is possible to identify that a problem has occurred in the system, and by identifying the place where the route failed, it is possible to identify the location where the problem occurred. it can.

In this case, unlike the above-described method of comparing the normal transmission route information and the transmission route information, the transmission route information includes not only the information of the successful passing but also the information of the passing failure. It is only necessary to identify the route information, that is, the process of comparing the regular transmission route information with the transmission route information can be omitted, and accordingly,
Processing can be simplified.

In the terminal 24, the system status is identified by identifying the return route information indicating the return route in which the return signal actually succeeded or failed.

Therefore, if any failure occurs in the system, the failure occurs on the regular return route to which the reply signal should go due to the occurrence of the failure. By identifying that the route has failed in the formal reply route, it is possible to identify that a problem has occurred in the system, and by identifying the place where the route failed, it is possible to identify the location where the problem occurred. it can.

Also in this case, unlike the above-mentioned method of comparing the regular reply route information and the reply route information, the reply route information includes not only the information of the successful passing but also the information of the failed passing. It is only necessary to identify the reply route information, that is, the process of comparing the regular reply route information with the reply route information can be omitted, and the process can be simplified accordingly.

Further, in this case, if the transmission signal is configured to identify the transmission route information that has actually succeeded or failed, then the return signal is configured to identify the return route information that has actually succeeded or failed. Accuracy can be improved in identifying the location where the error has occurred, and the location where the defect has occurred can be more accurately identified.

Also, the radio (D) 15 sends
Since the transmission route information is configured to be transmitted, when transmitting the transmission route information alone as the entire system,
That is, it is possible to suppress an increase in traffic as compared with the case where transmission route information is transmitted separately from the return signal.

On the other hand, the radio (D) 15 to the radio (C) 14
In the configuration in which the transmission signal is transmitted to the wireless device (A) 12 by relaying the wireless device (B) 13, the terminal 24 connected to the wireless device (A) 12 performs a normal transmission through which the transmission signal should pass. The system status is identified by comparing the normal transmission route information indicating the route with the transmission route information indicating the transmission route through which the transmission signal has actually passed.

Therefore, if any trouble occurs in the system, the transmission signal passes through a transmission route different from the regular transmission route to be transmitted due to the trouble, and the normal transmission route information and Since the transmission route information is different, the terminal 24 identifies that the two are different from each other, so that it is possible to identify that some trouble has occurred in the system. In this case, it is possible to identify the location where the failure has occurred.

Further, the terminal 24 is configured to identify the system status by identifying transmission route information indicating a transmission route through which a transmission signal has actually passed or failed.

Therefore, if any trouble occurs in the system, the transmission signal fails to pass through the regular transmission route through which the transmission signal should go through due to the trouble, and therefore, the transmission signal should pass through the terminal 24. By identifying that the route has failed in the legitimate transmission route, it is possible to identify that a problem has occurred in the system, and by identifying the place where the route failed, it is possible to identify the location where the problem occurred. it can.

Also in this case, unlike the above-described method of comparing the regular transmission route information and the transmission route information, the transmission route information includes not only the information of the successful passing but also the information of the passing failure. It is only necessary to identify the transmission route information, that is, the process of comparing the regular transmission route information with the transmission route information can be omitted, and the process can be simplified accordingly.

Further, if each wireless device is configured to transmit the reception electric field level of the transmission signal and the return signal together with the transmission route information and the return route information, the terminal 24 can receive the reception electric field level of the transmission signal and the return signal. Can be identified.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows. In a data communication system, the number of radios is six.
The number is not limited to the wireless device, and may be another number, and the telephone number of each wireless device is not limited to “51” to “56” and may be another number. Further, the transfer path information may have other contents as long as it indicates a path (connection relation) between the wireless devices.

The configuration may be such that all the radios are connected to the terminals, or the configuration may be such that there are radios not connected to the terminals. When the communication line is a PHS line, a configuration of only transceiver communication or a configuration in which transceiver communication, public communication, and private communication are mixed may be used. May be used.

There may be a configuration in which there are a plurality of terminals acting as host computers, one terminal being a normal operation computer and the other being a backup computer. The communication state information is not limited to identifying the reception electric field level, but may be configured to identify an error rate when various signals are received.

The terminal to which the wireless device is connected is not limited to the vending machine, but may be a gas meter, a remote display device, or a robot.
