产品特点/ Product features

本系统采用美国ATMEL微机作为主控单元，本系统具有可靠性高、操作方便、维修简便等特点。

The system uses the American ATMEL microcomputer as the main control unit, the system has the characteristics of high reliability, easy operation, easy maintenance and so on.

2. 主要用途及使用范围/Main use and scope of use

   机舱监测报警系统主要用于探测主机等各种设备阀置开关量的报警。如水、油、气的超温超压，水、油液位超限，电网绝源等。如果参数越限，则对应指示灯闪频并伴有声光报警，按消音键声响报警停止，报警指示灯变平光直至报警消除为止。

本系统各个单元之间采用RS－485通讯。由于采用RS-485总线型数字传输技术，使连接电缆只有四根（包括电源）。RS－485总线是美国电气工业联合会(EIA)制定的利用平衡双绞线作传输线的多点通讯标准。它采用差分信号进行传输；最大传输距离可以达到1.2 km；最大可连接32个驱动器和收发器；接收器最小灵敏度可达±200 mV；最大传输速率可达2.5 Mb/s。

The engine room monitoring and alarm system is mainly used to detect the alarm of the valve setting and switching quantity of various equipment such as the main engine. Such as water, oil, gas over temperature and overpressure, water, oil level beyond the limit, power grid source. If the parameter exceeds the limit, the corresponding indicator flash frequency is accompanied by an audible and visual alarm. Press the muffler key to stop the audible alarm, and the alarm indicator becomes flat until the alarm is eliminated.

RS-485 communication is adopted between each unit of this system. Due to the use of RS-485 bus digital transmission technology, there are only four connecting cables (including power supply). RS-485 bus is a multi-point communication standard developed by the American Electrical Industry Federation (EIA) using balanced twisted pair wire as a transmission line. It uses differential signal to transmit; The maximum transmission distance can reach 1.2km; Up to 32 drivers and transceivers can be connected; The minimum sensitivity of the receiver is ±200 mV; The maximum transfer rate is 2.5 Mb/s.
