specific Embodiment approach

[0050]Please refer to FIG. 2 , which is a schematic structural diagram of the network security bridge of the present invention. The network security bridge 3 includes a power management unit 31 , a program storage unit 32 , a data storage unit 33 , a hot start detection unit 36 ​​, a serial communication unit 34 , an MPU processor 35 and a network communication unit. Fig. 2 shows a kind of specific implementation mode of the present invention, and the network security network bridge 3 comprises two network communication units, namely the first network communication unit 37 and the second network communication unit 38, corresponding to two network segments---network segment 1 and Network segment 2. That is, the network bridge shown in the figure has only two network interfaces, which are respectively connected to network segment 1 and network segment 2.

[0051] The power management unit 31 is used to isolate and stabilize the external input power, and is responsible for volta...

Abstract

This invention discloses one industry safety control system, which comprises first and second networks and network safety bridge, wherein, the said network safety bridge is used to connect the said first and second networks to receive first network message as coded type to second network; receiving second network message to first network through set type.

Description

technical field [0001] The invention relates to industrial automation control, in particular to an industrial safety control system and a control method thereof. Background technique [0002] Since the field devices of the industrial Ethernet control system are connected by Ethernet and connected to the external network through the industrial Ethernet network, users can easily access the field devices through the industrial Ethernet network. But at the same time, it is also convenient for illegal users to use mature Ethernet technology to carry out malicious damage, which makes field devices and industrial Ethernet control systems face serious security risks and threats. [0003] If an illegal user accesses a malicious device in the industrial network, intercepts the data of a transmitter, and the illegal user tampers with the sampling or control data, and sends the tampered data to the actuator, this will lead to industrial Ethernet control systems are in a very dangerous ...
