求哪位高手帮忙翻译一段英文，关于PLC程序控制的，不要google翻译的，急，谢谢
当小屋内任意一个气体报警器达到报警上限时，送出干接点信号到小屋内控制报警系统，安全报警系统声光报警器报警并启动防爆轴流风机进行强制换气，报警控制系统输出DO信号到DCS系统。
小屋PLC联锁控制系统在配电箱内，分机可由小屋外开关强制启动，可在小屋外进门前启动分扇。
When any gas detector detects gas level above safety level, warning signal will be relayed to the warning control system inside the house. Safety alert system will trigger light and sound warnings and activate the fan to force air exchange. DO signal will be sent to DCS system.
The PLC interlock system for the house is in the electric box. It can be manually activated from outside the house and the fan can be also be activated from outside the house before entry.
