Specific embodiment
To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the application, instead of all the embodiments.Based on the embodiment in the application, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
A kind of read/writing control method of state constraint figure is provided in the embodiment of the present application, this method is applied to any one
Sensor front end is illustrated by taking first sensor as an example below, wherein sensor front end is mainly responsible for what pretreatment detected
Sensing data, and the state constraint of robot is calculated.As shown in Figure 1, this method specifically includes that
Step 101, it after first sensor front end determines that state constraint figure is in Read-Write Locks shared model locking state, reads
State constraint figure.
Wherein, Read-Write Locks shared model allows each sensor front end to read data, but does not allow that data are written.
Wherein, the locking state of Read-Write Locks shared model can be is obtained by one of following two approach:
The first approach, Read-Write Locks shared model locking state are to obtain after second sensor front end locks state constraint figure
It arrives.Wherein, first sensor front end is different from second sensor front end.
Specifically, second sensor front end is earlier than first sensor front end, according to Read-Write Locks shared model to state constraint
Figure locks, and first sensor front end does not need to lock according still further to Read-Write Locks shared model herein, directly reads state constraint figure i.e.
It can.
For the first approach, after the reading state constraints graph of second sensor front end, to the Read-Write Locks of state constraint figure
Shared model unlock.
Second of approach, Read-Write Locks shared model locking state are to obtain after first sensor front end locks state constraint figure
It arrives.
Specifically, in the state that state constraint figure is in and is not locked, first sensor front end is earliest according to Read-Write Locks
Shared model locks state constraint figure.
For second of approach, after the reading state constraints graph of first sensor front end, to the Read-Write Locks of state constraint figure
Shared model unlock.
In one specific embodiment, the first interface function of default setting is called in first sensor front end, by this first
Interface function judges whether state constraint figure is in Read-Write Locks shared model locking state, if so, directly reading state constraint
Otherwise figure locks the setting of state constraint figure for after Read-Write Locks shared model, reading state constraints graph.
Step 102, first sensor front end generates new state about according to state constraint figure and new sensor information
Beam.
Specifically, first sensor front end indexes node relevant to first sensor from state constraint figure, according to rope
The corresponding sensor information of the node guided to and new sensor information, generate new state constraint.
Step 103, first sensor front end is after state constraint figure locks, to state constraint according to Read-Write Locks exclusive mode
The new state constraint is written in figure.
Wherein, Read-Write Locks exclusive mode only allows first sensor front end that data are written, and before not allowing any sensor
Read data in end.
Wherein, first sensor front end is written into state constraint figure after new state constraint, to state constraint figure
The unlock of Read-Write Locks exclusive mode.After being locked in order to subsequent other sensor front ends according to Read-Write Locks exclusive mode, about to state
New state constraint is written in beam figure.
In one specific embodiment, first sensor front end call second interface function, by second interface function according to
Read-Write Locks exclusive mode is that after state constraint figure locks, new state constraint is written into state constraint figure.
Also, first sensor front end passes through second interface letter after new state constraint is added into state constraint figure
The Read-Write Locks exclusive mode unlock of several pairs of state constraint figures.
In one specific embodiment, sensor front end always has certain mode, finds out the mode, and fixed for the mode
An adopted general template, all sensor front ends are all based on the template and operate to state constraint figure.Think after analysis,
Sensor front end basic need carries out the following processing process: treatment process 1, reading state optimization figure;Treatment process 2, according to shape
State optimization figure and new sensor information, generate new state constraint;Treatment process 3 is written newly into state optimization figure
State constraint.
So, treatment process 1 is realized by defining first interface function, define second interface function and realize treatment process 3,
And define third interface function and realize treatment process 2, by first interface function, second interface function and third interface function
It is defined in general template, each sensor front end is handled state constraint figure according to the general template.First connects
Mouth function realizes that shared model locks, and second interface function realizes that exclusive mode locks, to realize multiple sensor front ends readings
Data during writing are synchronous, avoid the inconsistent situation of the state constraint figure of different sensor readings.
Also, each sensor front end is unified for using a template, is realized to any number of sensor front end
Unification, save the development amount of sensor front end.
For example, defining base class are as follows:
template<typename DataType,typename LookupReturnType>
class FrontEndBase(){
public:
FrontEndBase();
Virtual LookupReturnType Lookup ()=0;
Virtual Associate (const LookupReturnType&lookup_return_value)=0;
Virtual AddConstraints (const ConstraintList&constraints)=0;
DataProcess(const DataType&data);
}
Using the template that the base class is general as each sensor front end, each sensor front end needs to realize three pure void sides
Method, as three important steps.
In the DataProcess function of the base class:
FrontEndBase::DataProcess(const DataType&data){
//step 1, first interface function
graph_lock.lock_shared();
LookupReturnType lookup_return_value=Lookup ();
graph_lock.unlock_shared();
//step 2, third interface function
ConstraintList constraints=Associate (lookup_return_value);
//step 3, second interface function
graph_lock.lock();
AddConstraints(constraints);
graph_lock.unlock();
}
Certain specific sensor front ends may not be needed comprising the whole in above three interface function, for not needing
It the part for including can be directly vacant.
In the embodiment of the present application, first sensor front end is during carrying out read operation to state constraint figure, to state
Constraints graph is locked according to Read-Write Locks shared model, to guarantee that each sensor front end reads identical state constraint figure;The
One sensor front end adds state constraint figure according to Read-Write Locks exclusive mode during carrying out write operation to state constraint figure
Lock, so that other sensor front ends not will do it read operation when guaranteeing that new state constraint is written in state constraint figure, thus
Avoid the inconsistent situation of the state constraint figure of different sensor readings.To sum up, the embodiment of the present application realizes multiple biographies
