H92主机模块,FOXBORO中文使用说明
控制层网络采用实时、高效的Controlnet网络。Controlnet网络是一种高性能的工业局域网，具有开放性、高效率、多功能、确定性、可重复性和灵活性等特点，扩展性极强，可共享I/O，并具有强大、方便的网络组态，诊断功能及可靠性，网络通讯不会随着将来系统扩容时节点增加导致网络性能下降，通讯速率始终保持在5Mbps。
H92主机模块,FOXBORO中文使用说明结合现场工艺，优化了控制程序。在称量过程中采用变频方法调节给料速度，刚开始快速给料，等称量值接近设定值时变成慢速给料，以防称重过量，在更加接近设定值时变成点动给料，一点一点地微量自动给料，直至到设定值范围内为止。快称值、慢称值及点动值可通过上位机修改，客户可根据现场实际情况修改参数，即保证了称量速度，又能保证称量精度。磁兼容性(EMC)包含系统的发射和敏感度两方面的问题。如果一个单片机系统符合下面三个条件，则该系统是电磁兼容的：
① 对其它系统不产生干扰；
② 对其它系统的发射不敏感；
③ 对系统本身不产生干扰。
假若干扰不能完全消除，但也要使干扰减少到最小。干扰的产生不是直接的(通过导体、公共阻抗耦合等)，就是间接的(通过串扰或辐射耦合)。电磁干扰的产生是通过导体和通过辐射，很多电磁发射源，如光照、继电器、DC电机和日光灯都可引起干扰;AC电源线、互连电缆、金属电缆和子系统的内部电路也都可能产生辐射或接收到不希望的信号。在高速单片机系统中，时钟电路通常是宽带噪声的最大产生源，这些电路可产生高达300 MHz的谐波失真，在系统中应该把它们去掉。另外，在单片机系统中，最容易受影响的是复位线、中断线和控制线。干扰的耦合方式
1、 传导性EMI
一种最明显而往往被忽略的能引起电路中噪声的路径是经过导体。一条穿过噪声环境的导线可捡拾噪声并把噪声送到其它电路引起干扰。设计人员必须避免导线捡拾噪声和在噪声引起干扰前，用去耦办法除去噪声。最普通的例子是噪声通过电源线进入电路。若电源本身或连接到电源的其它电路是干扰源，则在电源线进入电路之前必须对其去耦。
The picture is not clear enough
The maximum definition of pictures taken by standard definition camera is 704 & times; 576. There is little video information that can be accommodated. Due to the lack of picture definition, the recognition effect is affected, which has an impact on the analysis and evidence collection of electronic police.
2) The stability of the equipment is not high
Most of the on-site processing equipment in the standard definition bayonet system are industrial control computers, while most of the transmission equipment are ordinary switches and optical fiber transceivers. The operation is not stable in the external harsh environment. The faults caused by dust accumulation, humidity, temperature, lightning and other factors may occur at any time. Therefore, a lot of maintenance work is brought and the later cost is high. Even so, it is difficult to ensure that the system can work continuously.
3) Weak EMC performance of the system
Electromagnetic compatibility EMC refers to the ability of equipment or system to meet the requirements in its electromagnetic environment and not produce intolerable
