The embodiment of the present invention provides dispatching workstations and adds " choosing " function, and successfully needs two steps to operate afterwards choosing
(select command+control command) could complete the once control to equipment, improve the reliability and security of dispatching workstations.
Using example
This example describes the overall process that user sends control command by scheduling system to equipment subsystem, as shown in figure 4,
Comprise the following steps：
Step 1, user in dispatching workstations by HMI chooses a certain target device subsystem (hereinafter referred to as target is set
It is standby), dispatching workstations send to application server and choose request；
Step 2, application server checks whether the state of the target device is seizure condition, if seizure condition, to
Dispatching workstations return to the response that cannot be chosen, and if not seizure condition, that is, idle condition, then being returned to dispatching workstations can
With the response chosen；
Step 3, dispatching workstations mark the target device to choose on HMI, i.e., in seizure condition, to prompt user
The target device has chosen success, while asks application server to choose mark to be arranged to take the target device；
" taking mark " is initiated and is cancelled by dispatching workstations, and the program on application server is responsible for writing the seizure condition
Enter system cache or removing.
Added in this example user treat manipulation target device function of choosing (above-mentioned steps 1 to step 3), are being dispatched
Internal system is set up for each controllable device and chooses mark." choosing " refer to internal system safeguard a kind of state, one
A controllable equipment same time only allows a user to choose.When a user needs to manipulate an equipment, it is necessary to elder generation
" choosing " equipment, could carry out next step operation.When user chooses a certain equipment, system chooses mark to put by the equipment
For " occupancy ", other users operate the equipment and are then prompted again, ensure that the uniqueness of control.After equipment is chosen successfully, it is
System should give prompting, and after user cancels operation, or after the completion of control, " choosing " mark of the equipment is revised as " empty by system
It is not busy ", release control power.This Functional Design ensure that the uniqueness to equipment manipulation in scheduling system level, ensure that and is dispatching
The internal system same time, same equipment can only have a personnel to be controlled operation.
Step 4, user sends select command to the target device；
Step 5, dispatching workstations caching select command, and identify the selection order using the UUID of target device, is dispatched
Work station sends select command by interface server to the target device；
The UUID of target device is generated in dispatching workstations, and UUID identifies all orders for an equipment,
When there is multiple users (dispatcher) to operate the more different equipment of traffic control stand control, dispatching workstations and application service
Device distinguishes each bar control command by UUID.
Step 6, which judges whether the system is controllable and returns the result (process of returning to school), if controllable, to
Scheduling system returns to response (success of returning to school) chosen successfully, if uncontrollable, return to selection failure response to scheduling system and (returns
School fails)；
If network timeout, dispatching workstations do not respond to after waiting for a period of time, and also correspond to return to school unsuccessfully.
In this example, " selection " process (above-mentioned steps 4 to step have been increased between scheduling system and equipment subsystem newly
6) so that security control of the scheduling system to equipment further upgrades, and " selects-returns by the system of dispatching and equipment subsystem
The interaction in school ", set up " choosing " mechanism equivalent in equipment subsystem aspect, ensure that in equipment subsystem aspect to equipment
The uniqueness of manipulation.
Step 7, dispatching workstations are shown chosen successfully by HMI to user；
Step 8, user sends control command in HMI to target device；
Step 9, dispatching workstations cache the control command, and identify the control command using the UUID of target device；
Adding command id operation in this example, (step 5 and step 9), employing 16 UUID, (UUID refers to
The numeral generated on one machine, it ensures that to aerial all machines when same be all unique) uniquely marking for order
Know, " select command " is identified with " control command " using same UUID, is avoided producing with other control commands and is intersected
Conflict, it is ensured that two step commands correspond to only one equipment, that is, ensure that two step commands are directed to the behaviour that same equipment carries out
Make.Clear command caches after order performs completion or failure.
Specifically, order caching can be carried out in the following ways：One piece of region is opened up in memory, establishes buffering area,
Unique mark is made with UUID, the content stored in buffer area includes：Command type (select command performs order), the mesh of control
Marking device information, control time etc..Context can be carried out when caching order to select command and control command to sentence
Disconnected, for a target device, it should be select command to be put into for the first time in buffer area, if not caching the life then
Order, be put into buffer area for the second time should perform order, and the order that can first judge currently to have cached before being put into buffer area is
It is not select command, whether order currently to be cached performs order, if not caching the order then.In addition, scheduling
Work station can only receive the receipt response (response in step 6) for handling select command after sending select command, send and perform life
The exectorial receipt response (response in step 13) of processing can only be received after order.If dispatching workstations are according in caching
It is incorrect to hold the response for judging to receive, then prompts user's error, terminates this operation.
By mentioned order caching mechanism, some error situations can be excluded.For example, target device A is made choice
Operation, but since memory error HMI receives exectorial receipt, alternatively, application server is not receiving the choosing of device A
When selecting order, these situations such as execution order are first have received, UUID is can be transferred through and order caching mechanism is excluded, to protect
Demonstrate,prove the correctness of control.
Step 10, dispatching workstations carry out the control command first time condition inspection, and after inspection passes through, which is ordered
Order is sent to application server；
First time condition inspection is checked in the HMI programs disposed on dispatching workstations, and the content of inspection is including following
It is one or more kinds of：
1) authority of user, that is, check whether the user possesses the authority of control；
2) whether target device has been chosen；
3) whether target device is in " with regard to status "；
