The value of the flag is “simulation” or “real machine”.

  Returning to FIG. 3, the model generation unit 202 is mainly realized by the processor 21. The model generation unit 202 generates test model data 35 indicating a test target model from the system information 31 and the device information 32. Specifically, the model generation unit 202 extracts a record corresponding to a communication command transmitted / received by a model included in the device information 32 from the system information 31. Then, the model generation unit 202 generates the test model data 35 by replacing the transmission source model and the transmission destination model included in the extracted record with addresses by referring to the device information 32.

  FIG. 8 shows an example of test model data 35 generated by the model generation unit 202. Records 351, 352, 355, and 356 in FIG. 8 correspond to the records 311, 312, 315, and 316 shown in FIG. 4, respectively. Since the communication device 13 is not a test target, the record corresponding to the record 314 in FIG. 4 is not included in the data shown in FIG. In other words, since the record corresponding to “wired terminal” is not included in the device information 32, the record corresponding to this model is not included in the data shown in FIG.

  The reference generation unit 203 is mainly realized by the processor 21. The reference generation unit 203 generates reference data 36 indicating a pass / fail criterion for the test from the test model data 35 and the determination formula information 33. Specifically, when the test model data 35 includes a record corresponding to the determination formula constituting the determination formula information 33, the reference generation unit 203 associates this determination formula with the record of the test model data 35. Thus, the reference data 36 is generated.

  FIG. 9 shows an example of the reference data 36 generated by the reference generation unit 203. In the record 361 in FIG. 9, the data 331 of the determination formula information 33 shown in FIG. 6 is associated with the record 351 of the test model data 35 shown in FIG. 8 via the communication command “Power-On”. 8 is associated with the record 352 in FIG. 8 via the communication command “Power-On-Done”, and is generated by combining these data 331 and records 351 and 352. Further, in the record 362 in FIG. 9, the data 334 in FIG. 6 is associated with the record 355 in FIG. 8 via the communication command “Power-Off”, and the record 356 in FIG. Since it is associated through “Power-Off-Done”, it is data generated by combining these data 334 and records 355 and 356.

  The test unit 204 is mainly realized by the processor 21. The test unit 204 assigns a flag to each device according to the rule selected from the designation information 34, and tests the communication in the simulation system configured according to the assigned flag. The simulation system is a system in which some or all of the devices of the communication system 10 are replaced with devices that are executed on the simulation based on the device information 32. Based on the test model data 35 and the reference data 36, the test unit 204 inputs information to a device constituting the simulation system, obtains information output from the device, and the obtained information is defined in the reference data 36. Test whether the specified criteria are met. Specifically, the test unit 204 transmits a communication command included in the reference data 36 on the simulation system, receives a communication command returned from a device that has received the communication command, and determines the received communication command. It is determined whether the expression is satisfied.

  However, the test unit 204 converts the protocol of the communication command from the one suitable for the simulation system to the one suitable for the communication system 10 when the device that is the transmission destination of the communication command on the simulation system is an actual machine, It outputs to the communication part 205 mentioned later. Further, the test unit 204 acquires a communication command received by the communication unit 205 from the communication system 10, and determines whether or not the acquired communication command satisfies a standard. Then, the test unit 204 outputs the determination result to the output unit 206.

  The communication unit 205 is mainly realized by the transmission / reception unit 25. The communication unit 205 transmits the communication command output from the test unit 204 to the communication system 10, receives the communication command transmitted on the communication system 10, and outputs the communication command to the test unit 204.

  The output unit 206 is mainly realized by the UI unit 24. The output unit 206 displays the result of the test executed by the test unit 204 to the user. That is, the output unit 206 outputs the result of testing the communication by the communication unit 205 using the determination formula included in the reference data 36. Note that the output unit 206 may output information including the test result to a storage device included in the communication test apparatus 20 or an external storage device connected to the communication test apparatus 20 via the network NW.

  Subsequently, a series of processes executed by the communication test apparatus 20 will be described with reference to FIGS. The process shown in FIG. 10 starts when specific application software of the communication test apparatus 20 is executed.

  The communication test apparatus 20 first acquires various data (step S1). Specifically, the acquisition unit 201 acquires system information 31, device information 32, determination formula information 33, and designation information 34.

  Next, the communication test apparatus 20 generates a test model (step S2). Specifically, the model generation unit 202 generates test model data 35 from the system information 31 and the device information 32.

  Next, the communication test apparatus 20 generates reference data 36 (step S3). Specifically, the reference generation unit 203 generates reference data 36 from the test model data 35 and the determination formula information 33.

  Next, the test unit 204 of the communication test apparatus 20 performs a test process (step S4). This test process will be described with reference to FIG.

  In the test process, as shown in FIG. 11, first, the test unit 204 reads one rule for assigning a flag from the designation information 34 (step S41). For example, the test unit 204 reads the rule 341 shown in FIG. 7 when executing step S41 for the first time.

  Next, the test unit 204 simulates data transmission / reception by a communication device with a simulation flag and communicates with a communication device with a real machine flag to form a simulation system (step S42). For example, when the rule 341 in FIG. 7 is read in step S41, the test unit 204 forms the simulation system 10a shown in FIG. The simulation system 10 a includes a simulation device 11 a that operates in the same manner as the communication device 11, a simulation device 12 a that operates in the same manner as the communication device 12, and a communication device 13 in a real environment.

  Next, the test unit 204 reads one determination formula from the reference data 36 (step S43). Thereafter, the test unit 204 transmits a communication command for obtaining a true / false value of the read determination formula on the simulation system (step S44). For example, the test unit 204 reads the record 361 in FIG. 9 and sends the communication command “Power-On” from the device with the address “192.168.5.11” to the device with the address “192.168.5.12”. Send to. In the simulation system 10a shown in FIG. 12, both the transmission source device and the transmission destination device of the communication command “Power-On” operate on the simulation.

  Next, the test unit 204 determines whether communication according to the read determination formula is performed on the simulation system (step S45). Specifically, the test unit 204 receives a communication command that the device that is the transmission destination of the communication command in step S44 responds on the simulation system, and the received communication command is read in step S43. It is determined whether or not the above is satisfied. For example, when the record 361 in FIG. 9 is read in step S43, the test unit 204 transmits the communication command “Power-On-Done” from the device having the address “192.168.5.12”. It is determined whether or not.

  When it is determined that the communication conforms to the determination formula (step S45; Yes), the test unit 204 outputs a result indicating that the criterion is satisfied (step S46). Specifically, the test unit 204 outputs information indicating that the criterion is satisfied to the output unit 206, and the output unit 206 displays a character string or a graphic indicating that communication satisfying the criterion has been performed. Thereafter, the test unit 204 executes Step S48.

  On the other hand, if it is determined that the communication does not conform to the determination formula (step S45; No), the test unit 204 outputs a result including an error indicating that the standard is not satisfied (step S47). Specifically, the test unit 204 outputs information indicating that the standard is not satisfied to the output unit 206, and the output unit 206 performs communication that does not satisfy the standard, communication is not performed, or communication. A character string or figure indicating an abnormality is displayed.

  Next, the test unit 204 determines whether or not an unselected determination formula is included in the reference data 36 (step S48). If it is determined that there is an unselected determination formula (step S48; Yes), the test unit 204 returns to step S43 and reads one unselected determination formula. Thereby, the test unit 204 reads out the determination formula included in the record 362 in FIG. 9, for example.

  On the other hand, when it is determined that there is no unselected determination formula (step S48; No), the test unit 204 determines whether or not an unselected rule is included in the designation information 34 (step S49). When it determines with there being an unselected rule (step S49; Yes), the test part 204 returns to step S41, and reads one unselected rule. Thereby, the test unit 204 reads, for example, the rule 342 in FIG. 7 and forms a new simulation system 10b shown in FIG. The simulation system 10b includes a simulation device 11b that operates in the same manner as the communication device 11, and communication devices 12 and 13 in an actual environment. And the test part 204 tests the communication made in the simulation system 10b by performing the determination contained in the reference | standard data 36 one by one for this simulation system 10b.

  On the other hand, when it is determined that there is no unselected rule (step S49; No), the test process by the test unit 204 ends, and the process executed by the communication test apparatus 20 is a series of processes shown in FIG. Return. And as FIG. 10 shows, when a test process is complete | finished, a series of processes performed by the communication test apparatus 20 will be complete | finished.

  As described above, the communication test apparatus 20 indicates the designation information 34 for designating a simulation device to simulate data transmission / reception among the communication devices 11 and 12 constituting the communication system 10 and the determination formula. Determination formula information 33 is acquired. Then, the communication test apparatus 20 simulates data transmission / reception by the designated simulation device, communicates with the communication device, and outputs information indicating a result of testing the communication using a determination formula. If this communication test apparatus 20 is used, the operator can easily perform a communication test by designating simulated equipment and preparing determination formula information. That is, it is possible to reduce the burden on the operator who performs the test of the communication system.

  The determination expression of the determination expression information 33 is an expression for determining the order in which specific data is transmitted between communication devices, and is described in a predetermined grammar. For this reason, even if the operator is switched, the judgment formula is not changed, and the risk that ambiguity remains in the test standard and the risk that the test standard and the test content are flawed can be reduced.

  In addition, according to each rule of the designation information 34, an actual machine to be subjected to a communication test is designated from a plurality of devices constituting the communication system. For this reason, a large number of communication tests can be efficiently performed by aggregating the rules into the designation information 34.

  Further, by using the temporal logic formula, the test unit 204 can perform an efficient test by a so-called model verification technique.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment.

  The determination formula according to the above embodiment describes the order in which communication commands are transmitted as specific data, but is not limited to this. For example, the determination formula may determine data other than the communication command, or may describe the order in which the communication command is transmitted and the time interval. If the time interval at which the communication command is transmitted is described in the determination formula, it is possible to detect a communication abnormality when the response of the communication device to be tested takes an abnormally long time.

  The function of the communication test apparatus 20 according to the above embodiment can be realized by dedicated hardware or by a normal computer system.

  For example, the program 28 stored in the auxiliary storage unit 23 may be stored and distributed in a computer-readable recording medium, and the program 28 may be installed in the computer to constitute an apparatus that executes the above-described processing. it can.
