最早出现网络化门禁是在上世纪九十年代。随着门禁系统应用范围的日渐广泛,人们对门禁系统的诉求不再局限于单一的出入口控制,而是要求其同时具备门禁控制、考勤管理、楼宇自控等多种控制功能,并对系统的整合和远程控制功能有了非常明确的要求。 The earliest appearance of networked access control was in the 1990s. With the increasing application of access control system, people's demand for access control system is no longer limited to a single access control, but requires it to have access control, attendance management, building automation and other control functions at the same time, and has a very clear requirement for the integration of the system and remote control functions. 然而,传统门禁基于RS485通讯方式,传输距离和节点数量都受到限制,无法实现远程控制和智能化管理。基于以太网传输方式的网络化门禁应运而生,它不但解决了远距离的传输问题,在管理方面,也使更多服务器、工作站的参与成为可能,从而为客户提供多级、多模块的门禁管理。 However, the traditional access control is based on RS485 communication mode, which limits the transmission distance and the number of nodes. It is impossible to achieve remote control and intelligent management. Networked access control based on Ethernet transmission mode emerges as the times require. It not only solves the problem of long-distance transmission, but also makes it possible for more servers and workstations to participate in management, thus providing multi-level and multi-module access control management for customers. 顺应应用需求变化,许多门禁厂商都纷纷推出网络门禁产品。所谓网络化门禁是指基于TCP/IP协议进行数据传输的门禁系统,控制中心服务器与前端控制器都采用网络化结构,管理系统中各服务器和工作站(PC)之间也都通过网络进行数据传输。 In response to the change of application demand, many entrance guard manufacturers have launched network entrance guard products. The so-called network access control refers to the access control system based on TCP/IP protocol for data transmission. The control center servers and front-end controllers adopt the network structure, and the data transmission between servers and workstations (PC) in the management system is also carried out through the network. |
