Wherein, described 3rd preset duration is more than described second preset duration, and alternatively, described 3rd preset duration is permissible
Integral multiple for described second preset duration.For example, when described second preset duration is 15 seconds, described 3rd preset duration can
Think 30 seconds.
In information storage means provided in an embodiment of the present invention, only need to ensure that each storage device 130 stores each visitor enough
The information that family end 120 produced within the retention phase.Therefore, in order to save memory space, the capacity of each storage device 130 can be pressed
It is allocated according to following manner：There is a maximum information collection capacity in each client 120 within the described default retention phase, choose institute
There is the maximum in maximum information collection capacity, and using the product of this maximum and the number of described client 120 as all institutes
State the memory capacity sum of storage device 130.
The described default retention phase is the time that user wants the information in each storage device 130 to retain, can be according to reality
Situation is adjusted.For example, the described default retention phase can be 30 days.
Because described information storage method is to be evenly distributed according to number of tasks, rather than uniformly divided according to amount of storage
Join, for avoiding when not reaching the retention phase, the less storage device 130 of some memory capacity is filled with and causes loss of data, simultaneously
In order to load balancing is better achieved, in the embodiment of the present invention, the capacity of each storage device 130 can be equal.
According to above-mentioned capacity configuration mode, when any one storage device 130 is filled with, then it is considered that storage device
Time information memory in 130 has reached the described default retention phase.
Alternatively, under above-mentioned configuration, cause loss of data to prevent each storage device 130 to be filled with, one can be arranged
Monitoring server, described monitoring server deletes current time in each described storage device 130 at interval of the 4th preset duration
The storage content before the default retention phase before.
During enforcement, each storage device 130 can be when storing the information that each client 120 sends over during record storage
Between, and forming file directory, described file directory includes the storage time of all information.Described monitoring server is at interval of the 4th
Preset duration run-down this document catalogue, and the storage content before one default retention phase of retroversion in this scanning moment is deleted
Remove, to avoid each storage device 130 to be filled with.It should be noted that described 4th preset duration is less than the described retention phase.For example,
The described default retention phase can be 30 days, and described 4th preset duration can be one day.
The capacity of each storage device 130 was allocated according to the described default retention phase, and the storage of each storage device 130 is held
When measuring equal, be equivalent to the quantity of information sum that each client 120 in the described default retention phase is gathered equal according to the time
Assign to each storage device 130.
Assume storage device 130 described in a total of N platform, then in the case of all normal operation of every storage device 130, often
The quantity of information that in the described default retention phase by 1/N for the quantity of information that platform storage device 130 is assigned to, each client 120 is gathered it
With.
However, in fact it could happen that the non-serviceable situation of separate unit storage device 130 in actual application.When separate unit is deposited
Storage equipment 130 delay machine when, this quantity of information assigned by storage device 130 then cannot store, namely deposits in each storage device 130
The time that the information of storage can retain decreases 1/N.Therefore, when not yet reaching the described default retention phase, arise that some
The situation that storage device 130 is filled with, and this situation cannot detect.
Because the information storage means that the present embodiment provides are each client according to the current task number of each storage device 130
120 distribution target storage device, and the current task number of described each storage device 130 refers to transmit with each storage device 130
The quantity of the client 120 connecting, thus be likely to occur some clients 120 and continue to select stored full storage device
130 carry out information Store, thus causing loss of data.
In order to solve the above problems, alternatively, described information storage method can also comprise the following steps：Each storage sets
Standby 130 send alarm signal when being filled with to described monitoring server.
User can be reminded when monitoring server receives alarm signal, allow the user to check whether to deposit
In the storage device 130 of the machine of delaying, when exist storage device 130 delay machine when, can be according to the quantity handss of the storage device 130 of the machine of delaying
The dynamic partial content deleted in each storage device 130, in order to avoid loss of data.
As shown in fig. 6, being a kind of information storage means that another embodiment of the present invention provides, it is applied to client 120, institute
State client 120 to communicate with storage management apparatus 110 and multiple storage device 130.Below by the concrete stream shown in Fig. 6

Image information in the vehicle through traffic block port for the collection.
During enforcement, can prestore in described client 120 task control block, and it is fixed to be provided with described task control block
When device., in full first preset duration of every timing, sending information Store to described storage management apparatus 110 please for described intervalometer
Ask, so that described storage management apparatus 110 distribute storage device 130 according to described information storage request for described client 120.
Step S302：Receive the information of the target storage device that described storage management apparatus 110 send, and with described target
Storage device is set up transmission and is connected.
Alternatively, in each described first preset duration, described client 120 is required for setting up with a storage device 130
Transmission connects, no matter whether described client 120 collects information in this preset duration.By above-mentioned design, Neng Goubao
The information that card client 120 collects is uniformly distributed in each storage device 130 according to the time.
Step S303：The described transmission of monitoring connects the duration keeping, and connects, in described transmission, the duration keeping and reaches first
Discharge described transmission during preset duration to connect, and again send new information storage request to described storage management apparatus 110.
During enforcement, described client 120 can connect, by the described transmission of described intervalometer monitoring, the duration keeping.Described
Intervalometer can from described client 120 to described storage management apparatus 110 send request moment start timing it is also possible to from
The moment that described client 120 is connected with the foundation transmission of described target storage device starts timing, between two moment
Time difference is Millisecond, and specifically which moment to start timing from does not affect on the realization of this programme, and the present embodiment is to this not
It is restricted.
When full first preset duration of described intervalometer timing, described client 120 discharges described transmission and connects, and again
