Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
In the embodiment of the present application, provide a kind of optimization method and device of video monitoring, can arbitrate the monitoring request of user, avoid the conflict that video calls, promote the service efficiency of video system bandwidth.
Embodiment one:
Please refer to Fig. 1, Fig. 1 is the method flow diagram of the embodiment of the present invention one.As shown in Figure 1, a kind of optimization method of video monitoring, can comprise the following steps:
101, the weights of user at moment T are calculated.
User comprises at the weights of moment T: superpose income value in the Permission Levels of user and described user at the quantized value of the importance degree of moment T by allocating in advance.
Suppose that user is A1, then A1=P+M+E at the weights of moment T, wherein, P is user right rank, and M is the quantized value of the importance degree of moment T.In an embodiment, special occasions mark E can also be added, such as need emergency open to certain user to the calling of video monitoring time, user can be added in the weights of moment T, to increase the weights of this user at moment T.
102, user be added with pre-assigned camera weighted value at the weights of moment T, what obtain user calls weights.
Also add the weighted value of camera in the embodiment of the present application, in conjunction with camera weighted value, when calling the video of job site outbalance, the weight rank called can correspondingly shift to an earlier date.
103, receive the video call request of each user, call request carry described in user call weights.
104, call weights size described in basis, described user is sorted from front to back, obtains the call request queue of user.
In an embodiment, when calling weights described in each user and being equal, sort according to the time order and function order initiating to call.
105, according to the total bandwidth of video monitoring, from the queue of described user's call request, the cumulative total value of bandwidth shared by the forward and video call request of selected and sorted is less than the maximum N number of user of the number of described total bandwidth, described N be greater than 1 integer.
106, the call request of described N number of user is responded.
Please refer to Fig. 2, in one embodiment, in such as, a certain moment after the T moment, initiate calling Video Monitoring Terminal with new user, now, the weights that call of new user add in the lump and consider, the application's method also comprises step:
107, the video call request of new user is received.
108, the size that each calls weights is again compared.
109, described new user is updated in the queue of described user's call request.
In one embodiment, comprise after described new user being updated in the queue of described user's call request:
110a, new user is updated to position in call request queue and the N number of user last customer location that sorts and compares, if the name placement of new user rearward, then perform step 110b, otherwise perform step 110c.
110b, refuse the video call request of described new user.
110c, respond the video call request of described new user.
Because the total bandwidth in video monitoring is constant, after adding new user's call request, the medium response to be called of call request queue can be updated to, but simultaneously in order to avoid too much request takies the collapse that broadband causes occurring video monitoring system, the call request platoon ratio that the embodiment of the present application obtains in being called the sorting position of new user and last time comparatively, if sequence is after aforementioned N number of user, then refuse the video call request of described new user, if before N number of user or middle, then respond the video call request of described new user, reach the high object preferentially seized, realize the effect of arbitration.
In an embodiment, the call request responding described N number of user comprises: put in order according to the user of described user's call request queue, responds the call request of described N number of user successively.
The optimization method of the video monitoring that the embodiment of the present application one provides, what calculate user according to the Permission Levels of user, user at the importance degree of moment T and camera weighted value calls weights, size according to calling weights sorts to user, in total bandwidth range allowing to call, choose the user that multiple sequence is forward as far as possible, the maximization of the bandwidth availability ratio to video monitoring can be reached, avoid the conflict that video calls simultaneously.
