It elaborates below to the process of the determination method of the object.

In the embodiment of the present application, the determination method of object is collected after foundation and signal blind zone based on signal blind zone update It closes and forms the realization of signal blind zone library.In order to make it easy to understand, the foundation of signal blind zone and the renewal process of signal blind zone are first described, The use of signal blind zone is described again.During describing signal blind zone foundation, describes and distinguish for convenience, based on new pair As come the establishment process that describes signal blind zone, subsequent, the process that the use of signal blind zone is described based on object and is updated. It is to be understood that new object and object can be an identical object, be also possible to different objects, to this and it is unlimited It is fixed.

Before step S11, this method further include: according to the path that new object passes through in the first duration, generation area The signal blind zone of domain overlay path, wherein a length of when first never to be communicated with new object communication to new object recovery Between duration.

New object is travelled on road surface under mobile normal condition, and the electronic equipment with new object communication can be with every The control that the 15 seconds modes in interval receive the data that new object is sent or new object can in real time send electronic equipment System instruction is responded.It will be appreciated that the mode that electronic equipment receives the data that new object is sent can be with every Mode every 15 seconds receives data, is not intended as limiting.

In the case where the equipment of new object breaks down, this can cause new object that cannot carry out with electronic equipment Communication.Or in the case where the region that new object is located at is in not yet covered with networks region, new object just can not be with Electronic equipment carries out network communication, wherein not yet covered with networks region can be referred to as signal blind zone.Both of which can be with Prevent electronic equipment with new object from being communicated.Optionally, in the present embodiment, new object cannot be with electronic equipment Carrying out communication is caused by new object is in not yet covered with networks region.It cannot be logical with electronic equipment according to new object Letter, determine signal blind zone region, and then multiple new objects can cannot be communicated with electronic equipment determine it is multiple not Gather to form signal blind zone library with signal blind zone, realizes that new object cannot communicate in signal blind zone with electronic equipment, so that The frequency of electronic equipment false alarm reduces.

The process of the generation of signal blind zone can be with are as follows: cannot be with new object communication to new object restoring to communicate In first duration, the region for covering the path that new object passes through in first duration is determined as signal blind zone.

Cannot can be with the case where new object communication cannot be received with the electronic equipment of new object communication it is new The data that object is sent, the control instruction for being also possible to electronic equipment transmission cannot respond, and cause electronic equipment to new pair As being temporarily lost with control.It cannot communicated with new object after threshold time in electronic equipment, electronic equipment will Carry out alarm operation.

New object can be sent using continuously mode to electronic equipment during communicating with electronic equipment Data can also use in a manner of with polling cycle poll to send data to electronic equipment.Optionally, in the present embodiment In, new object uses in a manner of with polling cycle poll to send data to electronic equipment.Using with polling cycle Mode, can save the resource of electronic equipment, and then the communication efficiency of new object and electronic equipment can be improved.

Determine the first duration, it is thus necessary to determine that it cannot be communicated at the time of new object communication and with new object recovery by going out Between at the time of.Cannot with may be at the time of new object communication a upper moment to electronic equipment send data after poll In cycle time behind entering signal blind area, it is also possible to be that new object just terminates to send out to electronic equipment in polling cycle Entering signal blind area when sending data.It is thus impossible to that can be that new object can also at upper one at the time of new object communication At the time of being determined at the time of at the time of enough communication with electronic equipment plus after duration corresponding after polling cycle, or New object with electronic equipment at the time of can also communicate for upper one between the next moment adjacent with a upper moment Intermediate time.

Optionally, in the present embodiment, it is impossible to be determined as upper one and electronic equipment at the time of with new object communication At the time of at the time of communication plus after duration corresponding to polling cycle.In this way, when can be clear from first Initial time in length to calculate the path length passed through in the first duration, and then determines signal blind zone.

After determining the first duration, in conjunction with the speed of new object, so that it may determine new object in the first duration The path of interior process.In detail, the speed of new object can be the average speed that new object travels on road surface, can also Thinking cannot be with before new object communication, and electronic equipment last time receives include in the data that new object is sent instantaneous Speed.According to the relational expression of speed and time, straight path length that available new object passes through in the first duration.Road The starting point of diameter can be determine cannot with position corresponding at the time of new object communication, the terminal in path can for New object restores position corresponding at the time of communication.

The new object of determination in the first duration by path after, the signal that the region overlay path can be generated is blind Area.In the mode in the region overlay path, the straight length between the starting point to the end in the path can be determined as covering Length of the region projection on road surface；Or the length based on the path, the both ends in the path are increased separately into preset length again Length afterwards is determined as the length that overlay area is projected on road surface；Or the length based on the path, by any in the path The length after being further added by preset length is held to be determined as the length that overlay area is projected on road surface.

It is understood that new object travelled on road surface when a length of first duration during, new object Driving trace can be one section of straight line, can be one section of curve, can be the polygon of multistage straight line path formation, can be more The figure that section curve is formed is also possible to the figure that curve and straight line are staggered to form.And new object is in the first duration The starting point of interior driving trace to the linear distance between the terminal of driving trace is the above-mentioned relational expression according to speed and time, The straight path length that available new object passes through in the first duration.That is, the region projection of signal blind zone Area to road surface can cover it is all between the starting point in path and the terminal in path can be from the driving trace of origin-to-destination Route.

Determining the region for covering the path, other than it needs to be determined that covering the projected length in the region in the path, also It needs to be determined that going out to cover the projection width in the region in the path.The projection width for covering the region in the path can be new object Width of roadway corresponding to the road surface of traveling, or the multiple value of the width of roadway.

It can permit after new object travels arrival one place towards first direction on the road surface that new object travels The object of Xu Xin can throw signal blind zone on the road surface towards with first party traveling back and forth in the opposite direction Width of the shadow on road surface is selected as width of roadway corresponding to the road surface of new object traveling.Both signal can be made blind in this way The region that new object passes through in the first duration can not only have been covered in area, but also the range of signal blind zone can be made not too big, To guarantee the accuracy of signal blind zone.

New object is only allowed to travel toward the direction on the road surface that new object travels, without allowing new pair Road as on the road surface towards the road surface that the direction running opposite with the direction or new object travel including multiple directions Face path makes the width that can be projected in signal blind zone on road surface in the case where road surface formation cross staggered road surface It is selected as the multiple value of the width of roadway.The situation that new object passes through the region back and forth can be covered in this way, and can examined The situation at the crossing that multiple directions direction is contained on road surface is considered, to guarantee the accuracy in the region of the signal blind zone determined covering.

Optionally, in the present embodiment, it is the length based on the path that signal blind zone, which is projected in the length on road surface, by this The both ends in path increase separately the length after preset length again and are determined as the length that overlay area is projected on road surface；Signal blind zone The width being projected on road surface is width of roadway corresponding to the road surface of new object traveling.The both ends in the path are increased respectively again Add preset length that can expand the range of signal blind zone, so that the signal blind zone generated includes real signal blind zone place as far as possible Region, guarantee the accuracy of signal blind zone.Because only need test object whether in the path of traveling whether by signal Blind area, that is, object is in the movable width of roadway of institute, if by signal blind zone, therefore, the projection of selection signal blind area Width on road surface is width of roadway corresponding to the road surface of new object traveling, and may not necessarily store needs with practical in this way The incoherent data in the signal blind zone wanted, save the resource of electronic equipment.

Please refer to Fig. 3.It is assumed that the endpoint in the path that new object passes through in the first duration is respectively A1, A2, new pair As the driving trace in the first duration is straight line, new object successively passes through A1 and A2, and the length in the path is 500 meters, newly Object where path width of roadway be 15 meters, preset length be 5 meters.The process of signal blind zone is determined according to new object It can be with are as follows: will cannot be set as A1 with the position of new object communication, the position between restoring to communicate with new object is set as A2. So when the path passed through in the first duration according to new path determines signal blind zone, by A1 along the fortune with new object It moves the position reached after 5 meters contrary of direction movement and is determined as B1, by A2 along identical as the direction of motion of new object Mobile 5 meters of direction after the position that reaches be determined as B2.When determining signal blind zone, by the boundary and path where B1 and B2 Width locating for boundary of the boundary as signal blind zone and non-signal blind area, the region in boundary is signal blind zone region.Letter The width that number blind area overlay area is projected on the path road surface where new object is 15 meters, the polygon that length is 510 meters Shape.

Please refer to Fig. 4.It is assumed that the starting point in the path that new object passes through in the first duration is cannot be logical with new object Corresponding position at the time of letter, and it is set as C1；The terminal in the path that new object passes through in the first duration be and new pair Corresponding position at the time of as restoring communication, and it is set as C2, driving trace of the new object in the first duration is that multistage is bent The figure that line is formed, and the path width of roadway where new object is 20 meters, preset length is 5 meters.It presets from path Point movement is E1 via the position reached after the linear distance being calculated, since the driving trace of new object determines for curve The linear distance of track starting point to final on trajectory, which is less than, out is calculated linear distance according to speed and duration relationship, therefore, needs Position C2 corresponding to reality at the time of preset position E1 is adjusted to communicate with the recovery of new object.According to new object Determine that the process of signal blind zone can be with are as follows: according to actual movement position, determine that new object is restoring logical with new object Position between letter is determined as C2.The position reached after C1 is moved 5 meters along the direction opposite with the direction of motion of new object It sets and is determined as D1, the position reached after C2 is moved 5 meters along direction identical with the direction of motion of new object is determined as D2. The region for covering road surface length between width of roadway and D1 and D2 is determined as signal blind zone region.

Figure that the track travelled on road surface due to new object either straight line, curve, multistage straight line are formed or The figure that multistage curve is formed, new object travel on road surface always, and therefore, the road surface institute that new object is travelled is right The width of roadway answered is determined as width of the signal blind zone region projection on road surface, it is ensured that the signal blind zone determined can be with Including region corresponding to all motion profiles between the beginning and end of the motion path of new object is covered.

Please refer to Fig. 5.It will be appreciated that the direction in path where the object for including in a signal blind zone can be with The same direction direction is corresponded to for a paths, or mulitpath includes multiple and different direction direction.If path It is oriented different directions direction, according to object from cannot be with object communication to the road for restoring communicate each direction process with object Diameter generates the region for covering the path of each direction direction, then will cover the regional ensemble in the path of each direction direction, obtains The region of one entirety, and the region of the entirety is determined as the signal blind zone on the region.It is readily apparent that, this signal Blind area is the signal blind zone for covering the path of multiple and different direction directions.In the present embodiment, as described in Figure 5, circle Domain is confirmed as signal blind zone.

It according to process above, repeats, multiple signal blind zones can be obtained, multiple signal blind zones are gathered, it can be with Form signal blind zone library.

Judge whether the position at the first moment is located in signal blind zone, needs according to the second moment before the first moment Position and motion state, to predict to determine the position at the first moment, then to judge whether the position at the first moment is located at signal blind In area.

First moment and the second moment can be two adjacent moment, when being also possible to two with interval duration It carves, in the present embodiment, the first moment and the second moment are two moment with interval duration.Since the speed of object is usual Change in the process of moving it is smaller, it is possible to according to the location of the prediction of speed subsequent time object of object.Therefore, It is communicated in object between electronic equipment, when object sends the data about the position of object to electronic equipment, in order to save The about system resource of electronic equipment improves operational efficiency, can be received according to interval duration between electronic equipment and object The communication of data is sent out, the first moment and the second moment are with two moment of interval duration, this can achieve and electronic equipment The effect of communication synchronization between object.

The label for being used for mark action can be given to each signal blind zone determined, each label is corresponding One different signal blind zone.If new object passes through different paths, at least one signal blind zone is determined, at least one The overlay area area of each signal blind zone is determining in signal blind zone.It is possible to according to when new object is second The data comprising the location of the second moment information sent to electronic equipment are carved, and according to corresponding to the region of signal blind zone Location information, a signal blind zone is selected from least one signal blind zone to judge whether object is located at the first moment Signal blind zone.If only establishing a signal blind zone by new object, then, then need to judge object the first moment whether In the signal blind zone.

Judge whether object is located in signal blind zone in the position at the first moment, it can be according to the distance moved on path When size is identical as the linear distance that calculating is determined, whether the position coordinates for judging that the first moment of object is reached are located at signal In coordinate range corresponding to blind area, if the position coordinates that the first moment of object is reached are located at coordinate corresponding to signal blind zone In range, then it represents that the first moment of object is located in signal blind zone.It can also be according to object in the position at the second moment, by second The position at moment is determined as first distance at a distance from the path between the position close to the edges of regions of the signal blind zone of object, The size relation of first distance and linear distance is judged, if first distance is less than linear distance, then it represents that the first moment of object position In in signal blind zone.

Optionally, in the present embodiment, judge whether object is located in signal blind zone in the position at the first moment, in use The mode for stating the first is realized.Corresponding information includes object motion state letter in the data that object is sent to electronic equipment Breath, further includes the real-time positioning information for having object.It therefore, can be with object-based real-time positioning information, it may be convenient to calculate The position of object out, to judge whether the first moment of object position is in signal blind zone.

In detail, the motion state of object may include the movement velocity and acceleration of object.Existed according to the object of acquisition Duration between the movement velocity at the second moment and the second moment and the first moment, and the pass according to displacement and Velocity Time System, is calculated the linear distance that object travels in this section of duration of the second moment to the first moment.

Using object in the position at the second moment as initial position, object is from the second moment along the movement at the second moment Directional velocity moves on the path where object.According to the path where linear distance and object, determined on path pair As in the position that first moment will reach, wherein the initial position of the position and object that will reach is in the path On distance be road surface distance, road surface distance is identical with linear distance, initial position be object at the second moment positioned at path On position.That is, object, which is moved the position reached after the linear distance along the path where object, is determined as The position that one moment object will reach.According to the position that the first obtained moment object will reach, judged for the first moment pair As whether the position that will be reached is located in signal blind zone.

In detail, it is sat according to the longitude coordinate and latitude that obtain the position that the first moment object determined will reach Mark；And obtained on road surface as where the region projection where signal blind zone in object again, the polygon information determined, then Judge point corresponding to position that the first moment object will reach whether in the figure that signal blind zone is determined.

As the first possible implementation, after step s 11, before step S12, this method further include: root According to the area of signal blind zone and the corresponding relationship of duration, determine object by required for signal blind zone from least one duration Duration threshold value.

In this implementation, the determination of duration threshold value and the area of signal blind zone are related.In detail, signal blind zone area Greatly, corresponding duration threshold value is big；Signal blind zone area is small, and corresponding duration threshold value is small.

According to the minimum value and maximum value of signal blind zone area, signal blind zone area is divided into the area threshold of different range Value.Signal blind zone area value is in the area threshold of different range, and corresponding duration threshold value is different.For example, signal blind zone For area less than 500 square metres, duration threshold value is 3 minutes；Signal blind zone area is more than or equal to 500 square metres, less than 1500 squares Rice, duration threshold value are 5 minutes；Signal blind zone area is more than or equal to 1500 square metres, and less than 5000 square metres, duration threshold value is 10 Minute.First according to the size of signal blind zone area, the duration threshold size of object is preset.

Multiple signal blind zones are gathered to form signal blind zone library, and each signal blind zone library is determined uniquely to identify. When object moves to some signal blind zone, it is blind to obtain the signal for the unique mark being had according to the signal blind zone The corresponding duration threshold value in area.If object in the signal blind zone, cannot be more than duration threshold value with the duration of object communication, institute is right The duration answered sends warning message to personnel relevant to object then being judged as the object is in abnormal condition.

As second of possible implementation, after step s 11, before step S12, this method further include: root The motion state in the path and object that are covered according to signal blind zone determines object by duration threshold required for signal blind zone Value.

In this implementation, the path phase that the determination of duration threshold value is covered with the motion state of object and signal blind zone It closes.In detail, in this implementation, the length of motion route determined by the movement velocity of the first duration of object and object with The length of signal blind zone area is related, and the movement velocity of object is big, and duration threshold value is small；When the movement velocity of object is small, when Long threshold value is big；The length of signal blind zone is big, and duration threshold value is big；The length of signal blind zone is small, and duration threshold value is small.The movement speed of object The length of degree and signal blind zone can all influence the size of duration threshold value.

According to the driving trace of object, the path that object will be mobile by signal blind zone is determined, then thus make object and exist The length of driving path is needed in signal blind zone.In the present embodiment, motion state includes current kinetic speed and mean motion At least one of speed.The length of driving path, and the current fortune according to object are needed in signal blind zone according to object Dynamic speed or average movement velocity, determine object by duration threshold value required for signal blind zone.

If object has been in signal blind zone in the position at the first moment, the first moment electronic equipment Through that cannot be communicated with object, therefore, the current kinetic speed at the first moment can be by the movement velocity at the second moment and right As the driving status before the second moment determines.

According to the current kinetic speed or average movement velocity of object, determine object by first required for signal blind zone Beginning duration；Initial duration is increased into error duration, obtains object by duration threshold value required for signal blind zone.

The length of driving path is needed in signal blind zone according to the current kinetic speed or average movement velocity of object, object The relationship of degree and movement velocity and displacement, is calculated the initial duration that object is needed by signal blind zone.

To increase an error duration on the basis of the initial duration being calculated, this can reduce because of movement velocity Caused error.This is because the movement velocity at the first moment being located in signal blind zone cannot obtain in real time, but according to the What the speed and history driving status at two moment were determined, accordingly, it is determined that the first moment movement velocity gone out and actually the One moment movement velocity is variant.

Increase error duration on the basis of growing at the beginning, error duration can be a fixed value, can also be according to letter Error duration in the area setting different range of number blind area.Optionally, in the present embodiment, error duration is blind according to signal Error duration in the path length setting different range in area.This is because the reason of increasing error duration is compensation campaign speed Caused by error, the different path of distance that object passes through, error caused by movement velocity is also different, in this way more Duration threshold value can be accurately determined out.

In two kinds of above-mentioned implementations, former mode can the simple and quick long threshold value of timing really, latter side Formula can more accurately determine duration threshold value.It is little in the value that signal blind zone is projected in the width on road surface, to signal blind zone area The influence of domain area is little, and when signal blind zone area is lesser, selects former mode to determine duration threshold value, because of face Product is small, and the duration of process will not differ too big, therefore, can set a suitable median as duration threshold value.

Determine from cannot with object communication in restoring time for communicate with object, the length in the path of object process compared with When long or travelable on the path velocity interval can be very big, latter approach is selected to determine duration threshold value, this It is duration threshold value to be determined according to the different motion state of object because influence of the movement velocity to duration of object is big.

Object is being determined after the first moment was located in signal blind zone, further according to the duration threshold value judged after the first moment Inside whether can with object communication, to determine whether object is in normal condition.

Whether that is, can judge that can object execute electricity with object communication in duration threshold value after the first moment The instruction that sub- equipment is sent, or judge that can electronic equipment receive the data of object transmission.

Step S13: if so, determining that the object is in normal condition.

Cannot with the reason of object communication there are two, one may be because object be in signal blind zone, electronic equipment The data of object transmission cannot be received in preset duration, it will generate warning message；Another possibility is that object itself is pacified The equipment of dress breaks down, so that cannot be with object communication, to generate warning message.

Under normal circumstances, object moves traveling on road surface, by cannot be with the knot of object communication caused by signal blind zone Fruit be it is temporary, when object sails out of out outside signal blind zone, the communication with object can be restored, therefore, a process can be set Signal blind zone, cannot be with the duration threshold value of object communication.It, can be from cannot be with the shape of object communication in the duration threshold value of setting State is transformed into be communicated with object recovery, then means that the reason of object cannot be communicated within this time with object is to enter Signal blind zone rather than may be due to causing object-based device failure.It, can not be in the duration threshold value of setting Object restore communication, then mean object may be due to equipment fault caused by cannot need to send with object communication Warning message reminds personnel relevant to object to carry out checking processing.It therefore, can be by judging the duration after the first moment In threshold value whether can with the object communication, to determine whether object is in normal condition.

After step s 13, this method further include: determine can be with object communication in duration threshold value when, obtain from the Second duration of one moment between at the time of restoring to communicate with object；The new road passed through in the second duration according to object Diameter, formation zone cover the new signal blind zone in the new path；Signal blind zone and new signal blind zone be superimposed and to be formed Region is determined as updated signal blind zone.

Determine in duration threshold value can with after object communication, it is meant that the region passed through within this time is that signal is blind Area.Different objects restores possible and different at the time of communication, then it is determined that region corresponding to the signal blind zone come out is just It can be different.Therefore, signal blind zone can be updated, is determined and the practical signal blind zone region being more consistent.

In detail, second duration of first moment between at the time of restoring to communicate with object is obtained, by the first moment pair The position of elephant is to the new path passed through at the time of restoring and communicate with object, based on the determination side of the signal blind zone of foregoing description Method determines new signal blind zone.New signal blind zone is superimposed the region to be formed with above-mentioned signal blind zone to be determined as being updated Signal blind zone.

Jointly in this area or area corresponding to the multiple in this area path of same target by multiple objects Domain calculates, and is updated amendment to the signal blind zone.When quantity by the different object in the signal blind zone or same Object after the number of the signal blind zone reaches preset value, then, object last time amendment is updated into the region determined It is determined as the signal blind zone in the position.

In addition, when object through the region in the signal blind zone determining, it is assumed that electronic equipment restores logical with object Letter, and in the area, after the number that can restore to communicate with electronic equipment reaches preset threshold, then, then by the region It is determined as non-signal blind area.I.e. object can be communicated with electronic equipment in the area, and object is in normal condition.

It is assumed that already existing signal blind zone R1-R2, cannot be determined as with position corresponding at the time of object communication S1, corresponding position is determined as S2 at the time of restoring to communicate with object.According to the position and signal blind zone R1- for judging S1 and S2 Positional relationship corresponding to R2, it can be deduced that whether S1 and S2 is located in the R1-R2 of signal blind zone.If S1 is in signal blind zone R1- In R2, S2 is located at except the R1-R2 of signal blind zone, it is possible to which the amendment of R1 point is updated to S1, the amendment of R2 point is updated to S2. And according to the generating process of above-mentioned signal blind zone, generates comprising S1 to the signal blind zone in paths all between S2, complete signal The process that blind area amendment updates.
