Guangzhou entrance guard system is pointed out that the domestic subway entrance guard system application status
Is a large number of new technology and new product introduction: today, with the constant development of new technology, domestic subway began actively the application of new technology and the increasing maturity of the entrance guard system, such as applying distributed database, realize the multilevel data storage, etc. , by applying these new techniques, entrance guard system has a variety of network structure, security and stability are also secured, can be more efficient to transmit data information, there are more powerful system function.
2 it is to apply different brand, increase the compatible with difficulty, in the process of entrance guard system technology development, subway lines of different construction period, will be differentiated entrance guard system to the application, thus isolated the access control data of different lines, not unified data effectively.
Because various lines of entrance guard system are independent construction completed, the database did not undertake unity, then for different line data from the entrance guard system, interconnection is unable to achieve the purpose of enjoyment, not real-time tracking and management to the authorized personnel access across the lines, so that it may appear the phenomenon such as the illegal use of entrance card, staff management and monitoring quality of entrance card work have been affected.
Three is complex: across the line authorization investigation found that now every line in the authorization and management of the entrance card, will be independent of the central device to the application level up, in the other across authorized transfer station staff and line personnel, will increase the difficulty of the work authorization, the normal work of the staff within the restricted areas will be affected.
At the same time, the fault card could not be found timely and efficiently and processing, in a larger extent, affects the safe operation of each line.
