2, the processing table 13 and the state transition table 15 as one piece of state transition information 21a, and the event value and the event name, the current state value and its state name, and the state value to be transitioned to next, for each set of state and event And its state name,
The sequence of process indexes and process names are collected and stored and managed. On the contrary, the state transition information conversion unit 18 converts the state transition information 21a into event table 1
1, the state table 12, the processing table 13 and the state transition table 15 can be expanded. Therefore,
The user can modify the created state transition information.

Next, the sequence execution operation in the event driven process execution device 3 will be described. First, the operation of selecting the state transition information 21a, 21b, 21c, 21d, ... Of the state transition information storage device 2 used by the state transition engine 30 will be described. The state transition information storage device 2 is
For each control of the target process 60 (for example, for bank A, for bank B, ...), a plurality of state transition information 21a, 21b, 21.
It stores and manages c, 21d, .... A user of Bank A using the state transition engine 30 causes an event having a request to select the state transition information 21a for Bank A, for example, the input of a specific code known only to the user of Bank A.

Event analysis unit 3 of state transition engine 30
When receiving an event having a request to select the state transition information 21a for bank A, 1 notifies the state transition information selection unit 34 of the event. State transition information selection unit 3
4 selects the state transition information 21a for Bank A online based on the notification and determines the type of processing sequence provided to the state transition engine 30, that is, for Bank A,
Stores and manages the type of processing sequence (for bank A).

Next, the sequence execution operation when an event for the target process 60 is received will be described. For example, if the current state of the target process 60 is state 1,
The state management unit 33 stores that the state value is 201. When the event interpretation unit 13 receives the event 4 with the event name = event 1, the event interpretation unit 13 analyzes the event value of the event 4 and notifies the state transition information interpretation unit 32 that the event value is “101”. The state transition information interpretation unit 32
The current state of the target process 60 is acquired from the state management unit 33, and the state transition information 21a of the state transition information storage device 2 is searched through the state transition information selection unit 34 using the state value 201 and the event value 101 as keys. By doing so, the processing index and the processing sequence at the time of receiving the corresponding event in the corresponding state are acquired, and the actual processing control unit 35 is notified of the acquired processing index and processing sequence.

The actual processing control unit 35 refers to the processing index table 70 (see Table 3), acquires the function start address corresponding to the notified processing index, and issues the acquired function start address to the actual processing unit 50. To do. As a result, the actual processing unit 50 executes the actual processing from the issued function start address. Therefore, the processing setting field 15γ1
, The function start address [addr1], [addr]
2] and the function of [addr3] are sequentially executed. The execution of the actual process uses the process index as an intermediary to refer to the function start address by the process index table 70. Therefore, the user can freely change the processing content by changing the actual processing portion of the actual processing unit 50 even in the same processing sequence. When the execution of all the processes is completed, the state transition information interpretation unit 32 sets the next transition state value 202 in the state management unit 33, and waits for the next event. Therefore, it is possible to control the target process 60 using the state transition engine 30.

Next, the verification operation of the processing sequence generated by the sequence creation device 1 will be described. Here, there are the following three cases in the verification of the processing sequence. (1) When verifying the processing sequence of the predetermined state transition information 21a currently used by the predetermined state transition engine 30 (for example, for bank A) to control the target process 60. (2) Regardless of which event-driven process execution device 3 uses which state transition information 21a, 21b, 21c, 21d, ... Arbitrarily created and stored in the state transition information storage device 2 State transition information 21
When verifying the processing sequence of a, 21b, 21c, 21d, .... (3) This is a case where the operation is verified for the processing sequence (for example, for bank A) developed in the state transition table 15 currently being created.

Here, in the above cases (1) and (2), the state transition information 21a,
21b, 21c, 21d, ... Are stored, and the state transition engine 30 stores the state transition information 21a, 21b, 21c, 21.
Since it is actually operating using d, ..., It is necessary to verify the processing sequence without stopping the event-driven process execution device 3. On the other hand, in the case of the above (3), the state in which the event-driven process execution device 3 has not reached the actual operating state and the state transition information storage device 2 does not store the state transition information 21a being created. Is. Therefore, in the cases of (1) and (2) above,
In the case of (3), a different verification operation is performed.

In the case of the above (1), the user of the sequence creation device 1 determines which state transition information 21a, 21b, 21c of the state transition information storage device 2 by the user of the event driven process execution device 3 from the viewpoint of safety. , 21d, ... It is often impossible to know if they are using. In this case, from the state transition information 21a used by the user of the event driven process execution device 3 to the state transition table 1
In order to develop the processing sequence in 5, the state transition editor 14 and the pseudo event generation unit 17 are used to generate an event for inquiring the type (for bank A) of the state transition information 21 that the state transition engine 30 is currently referring to. generate.
The event analysis unit 31 analyzes the event type of this event received from the pseudo event generation unit 17, and notifies the state transition information selection unit 34 of the event value. The state transition information selection unit 34 notifies the state transition information conversion unit 18 of the type (for bank A) of the state transition information 21 referred to by the current state transition information interpretation unit 32. The state transition information conversion unit 18
The target state transition information 21a, that is, the one for bank A is read online from the state transition information storage device 2 and expanded to the event table 11, the state table 12, and the processing table 13 in the state transition information 21 for bank A. At the same time, it is expanded in the state transition table 15 as a processing sequence.

In the case of (2), the user of the sequence creation device 1 uses the state transition editor 14 to set arbitrary state transition information 21a, 21b, 2 in the state transition information storage device 2.
One of 1c, 21d, ... Is designated. The state transition information conversion unit 18 uses the designated state transition information 21a, 21
, b, 21c, 21d, ... Are read online from the state transition information storage device 2, expanded into the event table 11, the state table 12, and the processing table 13 in the state transition information 21 for bank A, and the state transitions are performed. It is expanded in the table 15 as a processing sequence.

In the case of (3), the processing sequence is expanded in the state transition table 15 currently being created. In addition,
In any of (1) to (3), the operation after the processing sequence is expanded in the state transition table 15 is
Is the same.

When verifying the processing sequence, the user of the sequence creation device 1 first activates the state transition editor 14 and verifies the processing sequence developed in the state transition table 15 by pressing the test button (not shown). Select). As a result, the state transition table 15,
The pseudo state setting unit 16 and the pseudo event generating unit 17 are displayed on the same screen of the monitor. The user refers to the state table 12 from the pseudo state setting unit 16 and sets the pseudo state in the state transition table 15. As a result, any state (for example, state 2) in the state setting field 15β (see FIG. 5) of the state transition table 15 is selected. Next, the pseudo event generation unit 17 to the event table 11
, A pseudo event is generated in the state transition table 15. As a result, any event (for example, event 2) in the event setting field 15α (see FIG. 5) of the state transition table 15 is selected, and the process setting field 15γ
2 is selected. Therefore, since the processing sequence set in the processing setting column 15γ2 is executed in a pseudo manner, the processing sequence setting content can be confirmed. In addition,
The processing sequence of the processing setting fields 15γ2, ... Selected in this way can be left as a log.

As described above, in the sequence creation device 1,
Not only generate the processing sequence,
Alternatively, it is possible to verify the operation of the processing sequence irrespective of the actual operation of the event-driven process execution apparatus 3 by pseudo-executing the processing sequence during the generation. Therefore, according to the sequence creation device 1, the state transition information storage device 2, and the event-driven process execution device 3 in FIG. 1, it is possible to efficiently generate, verify, and execute a processing sequence, which results in program development. It can be done efficiently.

In the above embodiment, the event-driven process control device of FIG. 1 was described as an online system for a plurality of banks, but it may be implemented in another system such as a facsimile communication system.
