Abstract
The invention belongs to the field of computer and communication, and particularly relates to a method and device for calling gate data with internal and external networks being isolated. The method comprises the following steps: S101, acquiring gate data of the internal network, wherein the gate data comprise text data and picture data; S102, screening external network text data according to the type of the gate data, synchronizing the screened text data to the internal network in real time and backing up; S103, judging whether a calling request exists in the picture data or not by using a picture proxy server, calling the picture data to the internal network based on cache levels according to the calling request, and backing up. Under the condition that the internal and external networks are isolated, the gate data are classified, the text data are synchronized and transmitted in real time by using a boundary access gateway, and the picture data are accessed as required and cached on a plurality of levels by using the picture proxy server, thereby solving the problem of resource waste due to occupation of a large number of transmission bandwidths and repeated access of pictures in the real-time data transmission process of gate picture data.
Description
Technical field
The invention belongs to Computers and Communication field, relate in particular to a kind of method and device of the bayonet socket data call for intranet and extranet isolation.
Background technology
Gate System full name is road vehicle intelligent monitoring and recording system, automatic monitoring, identification and the record of all motor vehicle information of the key sections such as highway, urban road, charge station is mainly used in passing through, system can provide the information such as the number plate, vehicle, the speed of a motor vehicle, running time, place of on-the-spot vehicle in real time automatically, and Ke command centre unifies bayonet socket or optionally deploys to ensure effective monitoring and control of illegal activities.Public security system has been built public security net and video private network at present, Gate System is built at video private network, but it is to carry out in public security net that system is used, therefore must realize bayonet socket data by border access platform enters public security net, for the user in public security net or operation system.
But, the following way of available technology adopting: all build respectively a set of bayonet socket platform at video private network and public security net, bayonet socket platform in video private network is synchronized to public security net platform bayonet socket data in real time, at public security net and video private network, all store respectively a bayonet socket data, the data that the user in two cover networks or operation system are used respectively place network.Because the data volume of picture is larger, in the process of transmission, the bandwidth resources of the border access platform of great amount of cost costliness will be taken, meanwhile, bayonet socket picture utilization rate and storage cell value ratio are lower, so repeated storage also will cause a large amount of fund input wastes.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of method and device of the bayonet socket data call for intranet and extranet isolation, be intended to solve video private network in public security net synchrodata, since the large occupied bandwidth resource of data volume of the image data of transmission, the crowded wasting of resources problem producing with repeated access image data of channel causing.
