Step S104, locates the current state of described collecting device with described state machine.
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
In the present embodiment, with described x-ray imaging system specifically DR system, and described collecting device is flat panel detector (can referred to as " flat board ") for example is described.In other embodiments, described x-ray imaging system can be the other system beyond DR system, and described collecting device also can be other equipment with described flat panel detector with similar functions.
Because technical solution of the present invention carrys out positioning acquisition equipment current state by the state machine comprising the various state of collecting device of structure, therefore, in the present embodiment, first all kinds of states of flat panel detector are simply introduced.
In the present embodiment, the state of flat panel detector comprises: starting state, off-mode, rebooting status, contextual processing state, acquisition state, align mode, holding state and malfunction.Wherein:
Starting state: initial state during flat panel detector initialization, after initialization completes, can automatically switch to holding state;
Off-mode: time flat panel detector exits, can be switched to this state;
Rebooting status: time flat panel detector re-starts initialized, can be switched to this state;
Contextual processing state: when flat panel detector receives control command request, this state can be switched to; Such as: the multi-mode of flat panel detector switches;
Acquisition state: when flat panel detector starts to carry out image acquisition time, this state can be switched to;
Align mode: when flat panel detector starts to calibrate time, this state can be switched to;
Holding state: when flat panel detector completes processing in above-mentioned state of task time, this state can be switched to;
Malfunction: when in above-mentioned a certain state, if there is mistake in the process of Processing tasks, this state can be switched to.
In the present embodiment, the above-mentioned all kinds of state based on flat panel detector can construct corresponding state machine, the construction method due to state machine dawn known to those skilled in the art, is not described in detail herein.
It should be noted that, above-mentioned every state of flat panel detector is that present inventor obtains result according to practical experience summary, although there is different conditions dawn known to those skilled in the art in flat panel detector, but in the Systematical control of flat panel detector, overall annotation is made to the status mechanism of flat panel detector, and systematically construct the state machine of flat panel detector, for realizing the location of flat panel detector current state, to be but not that those skilled in the art are easy to just thinkable.
In the state machine constructed, the state transition of flat panel detector is driven by outer/inner event (flat panel detector process various functions request also can automatically switch state), often kind of event type determines different state transition paths, and the dbjective state that described state transition path is undertaken after the initial state before state transition and completion status migration by flat panel detector formed.
It should be noted that, differentiation between external event from internal event is different based on the source of event, external event such as flat panel detector function request, cancel the process etc. that this function request is carried out, mainly derive from the request that user sends, internal event such as completes the process, the flat panel detector that carry out for described function request and breaks down and failture evacuation etc., then the Processing tasks or the task that are mainly derived from flat panel detector inside complete.
In the present embodiment, under the driving of inside and outside event, the overall process of flat panel detector state transition can reference diagram 2.In fig. 2, the direction of arrow represents that migration or perhaps the transition of flat panel detector state, the associated description corresponding with arrow represent the event that concrete driving condition moves.For example: if the initial state of flat panel detector is " holding state ", so under the driving receiving " gathering request " this external event, the state of flat panel detector will be moved, its dbjective state is " acquisition state ", therefore, " gather and ask " the wherein bar state migration path that " holding state-acquisition state " under driving is flat panel detector; If the initial state of flat panel detector is " align mode ", so under the driving occurring " calibration makes mistakes " this internal event, the state of flat panel detector also will be moved, its dbjective state is " malfunction ", therefore, " align mode-malfunction " under " calibration makes mistakes " driving is another bar state migration path of flat panel detector.
In the present embodiment, the state transition path according to the type determination flat panel detector of often kind of event specifically can comprise: set up the corresponding relation between the inside and outside event of every type and its various state transition paths supported in advance; According to described corresponding relation, determine the dbjective state corresponding with the type of current inside and outside event and the current state of flat panel detector.In the specific implementation, described corresponding relation can adopt the form of event and state mapping map to store, and the mapping table of described event and state is specifically as shown in table 1:
Table 1
| Event source | Initial state | Dbjective state |
| Gather request | Holding state | Acquisition state |
| Cancel and gathering | Acquisition state | Holding state |
| Collection completes | Acquisition state | Holding state |
| Break down in gatherer process | Acquisition state | Malfunction |
| Calibration request | Holding state | Align mode |
| Elimination of calibrations | Align mode | Holding state |
| Calibration completes | Align mode | Holding state |
| Break down in calibration process | Align mode | Malfunction |
| Flat condition abnormal failure | Holding state | Malfunction |
| Fault has been repaired automatically | Malfunction | Holding state |
| Dull and stereotyped control is asked | Holding state | Contextual processing state |
| Dull and stereotyped processing controls request failure | Contextual processing state | Malfunction |
| Start completes | Starting state | Holding state |
| Turn-off request | Holding state | Closed condition |
| Turn-off request | Malfunction | Closed condition |
| Flat board is restarted | Malfunction | Rebooting status |
| Restart | Rebooting status | Holding state |
In Table 1, " event source " refers to the type of inside and outside event, and such as " collection request " is the event of a type, and " breaking down in calibration process " (or being called " calibration makes mistakes ") is the event of another kind of type.
When reality is implemented, described event and state transition mapping table exist usually in a software form, and its configuration structure can with reference to following example:
<Nodeid＝'0'name＝'AcquisitionReuest'isCollection＝"0">
<Valueindex＝'0'description＝"PrepareEvent">3</Value>
<Valueindex＝'1'description＝"IDLEState">0</Value>
<Valueindex＝'2'description＝"AcquisitionState">1</Value>
</Node>
Wherein, PrepareEvent represents the event source that driving condition moves; IDLEState represents the state before state transition; AcquisitionState represents the state after state transition.
It is to be noted, when reality is implemented, the state transition path that dissimilar event can be supported is different, by analyzing the initial state and dbjective state that form state transition path, just can judge that can the current state of flat panel detector support the event of current appearance.For example, if the initial state of flat panel detector is " malfunction ", the state transition path now formed obviously is that the event of " gathering request " this type can not be supported, event for " fault has been repaired automatically " (or being called " failture evacuation "), " turn-off request " and " flat board is restarted " these types then all can be supported, and occur that once current the type of event can be clear and definite, then the dbjective state of flat panel detector is also can be well-determined.
As shown in Table 1, determine that the state transition path of described collecting device can comprise according to the type of described inside and outside event described in step S103 shown in Fig. 1:
If the type of described inside and outside event is for gathering request, calibration request or controlling request, the initial state in the described state transition path then supported is holding state, and the dbjective state in described state transition path corresponds to acquisition state, align mode or contextual processing state respectively;
If the type of described inside and outside event is shutdown request, then the initial state in the described state transition path supported is malfunction or holding state, then the dbjective state in described state transition path is off-mode;
If the type of described inside and outside event is Restart Request, then the initial state in the described state transition path supported is malfunction, and the dbjective state in described state transition path is rebooting status;
If the type of described inside and outside event is for completing or cancelling the process carried out for described function request, the initial state in the described state transition path then supported is carry out for described function request the state that processes, and the dbjective state in described state transition path is holding state;
If the fault that the type of described inside and outside event is described collecting device occurs, the initial state in the described state transition path then supported is the state that holding state or carry out for described function request processes, and the dbjective state in described state transition path is malfunction;
If the type of described inside and outside event is the failture evacuation of described collecting device, then the initial state in the described state transition path supported is malfunction, and the dbjective state in described state transition path is holding state.
As previously mentioned, due to when reality is implemented, the event that may produce current appearance does not support the situation in described state transition path, therefore in the present embodiment, after receiving the function request to flat panel detector, also whether can support that described function request verifies to the current state of flat panel detector, if the current state verifying out flat panel detector supports described function request, the current state of the flat panel detector in described state machine is then made to produce migration, if the current state verifying out flat panel detector does not support described function request, the current state then maintaining the flat panel detector in described state machine is constant, and this function request of user can be pointed out to perform.
That is, in the present embodiment, making the current state of the described collecting device in described state machine produce migration shown in Fig. 1 described in step S102, is perform after the current state verifying out described collecting device supports described function request.
The specific implementation process verified the request of flat panel detector function is as shown in Figure 3:
First perform step S301, receive the function request to flat panel detector.Described function request is generally initiated by user, can be specifically to gather request, calibration request, control request, Restart Request or shutdown request.
After receiving this function request, perform step S302, judge whether the current state of flat panel detector supports this function request, is perform step S303, otherwise terminate checking process.
About judging in step S302 that can the current state of flat panel detector support the specific implementation means of the event of current appearance, illustrating before this, repeating no more herein.
Perform step S303, make the current state of the flat panel detector in state machine produce migration.
Current state due to flat panel detector is confirmable, so when the current state of flat panel detector can support the event of current appearance, type according to this event just can determine corresponding state transition path, determines which kind of dbjective state flat panel detector should migrate to from current state thus.Such as: if the current state of flat panel detector is " holding state ", the function request now received is " calibration request ", the state transition path then determined should be " holding state-align mode ", and so flat panel detector should migrate to dbjective state " align mode " from initial state " holding state ".
Perform step S304, process this function request.Except making except the current state in state machine moves, also need to respond to function request, such as: if this function request is " calibration request ", then need the calibration process of carrying out flat panel detector, if this function request is " gathering request ", then need the image acquisition of carrying out flat panel detector.
In the present embodiment, by the controlling mechanism of state machine, whether the current state of collecting device is supported that the function request received verifies, can the illegal function request of filtering external, thus the possibility of makeing mistakes when reducing collecting device work, reliability is improved.
Because the current state of described state machine middle plateform detector is constantly moved along with inside and outside event-driven, the location of x-ray imaging system middle plateform detector current state so can be realized simply, efficiently by described state machine.
In the present embodiment, when flat panel detector breaks down, can also according to the current state of the flat panel detector of location to user report error message, described error message comprise flat panel detector under current state produce the type of fault, such as the fault occurred in the fault or gatherer process occurred in calibration process, again or flat panel detector is standby time produce fault.During by making a mistake when the request of flat panel detector processing capacity time, according to current state at once accurately reporting errors information to user, the related software modules of flat panel detector can be made thus to have stronger adjustable.
It can thus be appreciated that, in the present embodiment, for the state transition control procedure of flat panel detector, except the current state of location panel detector, can also comprise: according to the described state transition path determined, duty residing when location panel detector breaks down.Such as: if the state transition path determined specifically " align mode-malfunction ", then except the current state orienting flat panel detector is " malfunction ", can also orient residing duty when flat panel detector breaks down is " align mode ", so just can carry out failture evacuation process targetedly.
Owing to introducing the mechanism of malfunction in the control of flat panel detector, when so working under other state, there occurs fault, so flat panel detector is had an opportunity the fault that produces for current state, do specific aim process, if mistake can reset, flat panel detector so can be allowed to automatically restore to normal condition, so make the unification of flat panel detector fault be treated as possibility.
In addition, due to above-mentioned state transition control model for the supplier of flat panel detector or model all without any restrictions, different supplier or the flat panel detector of different model can be unified to use this state transition control model, therefore adopt the corresponding software module of this state transition control model to have stronger reusability in flat panel detector.

In described x-ray imaging system, the concrete enforcement of the state transition control device of collecting device with reference to the enforcement of the state transition control method of collecting device in above-mentioned x-ray imaging system, can repeat no more herein.
Based on the state transition control device of collecting device in above-mentioned x-ray imaging system, the embodiment of the present invention also provides the collecting device in a kind of x-ray imaging system.Still for described collecting device specifically flat panel detector be described, as shown in Figure 4, the flat panel detector that the present embodiment provides comprises: above-mentioned state transition control device 402; Service unit 401, is suitable for receiving described function request, and feeds back the current state of the described collecting device of described state transition control device location; Processing and control element (PCE) 403, be suitable for after the current state generation migration making described collecting device, control to process accordingly for described function request, and to described state transition control device feedback processing result, the fault that described result comprises in the process and processing procedure cancelled or complete and carry out for described function request occurs.
Those skilled in the art it is understood that, when reality is implemented, above-mentioned service unit 401, state transition control device 402 and processing and control element (PCE) 403 exist usually used as software module in flat panel detector, form software model as shown in Figure 4 thus, wherein service unit 401 and state transition control device 402 belong to abstract logic key-course, they can receive and filter the process request of client codes, and the panel function module abstracts interface in processing and control element (PCE) 403 inherit by the SDK of lower floor (SDK (Software Development Kit) of the flat panel detector that supplier provides).Therefore, the flat panel detector that the present embodiment provides also comprises SDK (Software Development Kit) 404.
During concrete enforcement, the flow process of the flat panel detector function request of the present embodiment as shown in Figure 5:
First by the request of user's Trigger Function, this function request is sent to service unit 401 with the form of client codes.
After service unit 401 receives this function request, state transition control device 402 can be committed to whether effective to verify this function request, namely whether the current state of flat panel detector be supported that this function request verifies.
