功能概述下表总结了MVME172LX VME嵌入式控制器的功能。微处理器60MHz MC68060或64MHZ MC68LC060处理器外形尺寸6U VMEbus内存4/8/16/32/64MB交错，ECC保护DRAM或4/8/16MB奇偶保护DRAM 128KB SRAM，带备用闪存一个Intel 28F016SA 2MB 8位闪存设备

1、检查周边情况——仔细检查变频器和周边环境的通风及照明情况。要确保通风设备能够正常运转，照明设备能够正常使用。

2、检查内部电缆——打开变频器柜门，检查内部电缆是否有损坏、电缆间的连接是否正确可靠、所有接地线是否牢固可靠、接地点是否有生锈问题。变频器内的所有螺栓和螺母应该每半年紧固一次，确保连接可靠。

3、检查所有电气连接的紧固度——查看变频器内所有回路是否有异常的放电痕迹，是否有怪味、变色、裂纹、破损等现象。检查所有功率单元的光纤有无损坏或松动，是否每个都插紧。

4、测量变频器绝缘——每次停机后长时间恢复运行，应用2500V的兆欧表对变频器及旁通柜的主回路进行绝缘测试，确保测试合格后方可起动。

5、认真查遗——每次维护变频器后，要仔细检查变频器柜内外有无遗漏的螺丝、弹簧片、螺栓及金属导线等物品，防止小金属物品在变频器风机起动后被吸入内部，造成变频器短路事故。

6、***清洁——用带塑料吸嘴的吸尘器或空压机等***清洁变频器内外及配电室，***设备周围无过量的尘埃，确保运行环境清洁。

7、启动前检查——特别是对电气回路进行较大改动后，要检查所有电气连接是否正确、牢固，防止“反送电”事故的发生。对于供水系统进行的控制，归根到底是为了满足用户对于流量的需求。在高峰时期需求量大，需能快速供水；低峰时应维持管压。其***根本的控制对象是流量，压力被用来做为控制流量大小的参变量。如果保持供水系统某处压力的恒定，也就***该处的供水能力和用水流量处于平衡状态，可满足用户的用水需求。

Summary of Features The following table summarizes the features of the MVME172LX VME embedded controller.Microprocessor 60MHz MC68060 or 64MHZ MC68LC060 processor Form factor 6U VMEbus Memory 4/8/16/32/64MB interleaved, ECC-protected DRAM or 4/8/16MB parityprotected DRAM 128KB SRAM with battery backup Flash memory One Intel 28F016SA 2MB 8-bit Flash device

1. Check the surrounding conditions - carefully check the ventilation and lighting conditions of the frequency converter and the surrounding environment. To ensure that ventilation equipment can operate normally and lighting equipment can be used normally.

2. Check internal cables - Open the door of the frequency converter cabinet and check if there is any damage to the internal cables, whether the connections between the cables are correct and reliable, whether all grounding wires are firm and reliable, and whether the grounding points are rusty. All bolts and nuts inside the frequency converter should be tightened every six months to ensure reliable connection.

3. Check the tightness of all electrical connections - check all circuits inside the frequency converter for any abnormal discharge marks, strange odors, discoloration, cracks, damages, etc. Check if the optical fibers of all power units are damaged or loose, and if each is securely inserted.

4. Measure the insulation of the frequency converter - After each shutdown, resume operation for a long time. Use a 2500V megohmmeter to conduct insulation testing on the main circuit of the frequency converter and bypass cabinet, and ensure that the test is qualified before starting.

5. Careful inspection - After each maintenance of the frequency converter, it is necessary to carefully check whether there are any missing screws, spring plates, bolts, and metal wires inside and outside the frequency converter cabinet to prevent small metal items from being sucked into the interior after the frequency converter fan starts, causing a short circuit accident of the frequency converter.

6. * * * Cleaning - Use a vacuum cleaner or air compressor with a plastic suction nozzle to clean the inside and outside of the frequency converter and the distribution room. There should be no excessive dust around the equipment to ensure a clean operating environment.

7. Pre startup inspection - especially after major changes are made to the electrical circuit, all electrical connections should be checked for correctness and firmness to prevent the occurrence of "reverse power transmission" accidents. The control of the water supply system is ultimately aimed at meeting the flow needs of users. During peak periods, there is a high demand for fast water supply; Maintain a certain pipe pressure during low peaks. The fundamental control object of * * * is the flow rate, and pressure is used as a parameter variable to control the flow rate. If the pressure at a certain point in the water supply system is kept constant, the water supply capacity and water flow at that point are in a balanced state, which can meet the water needs of users.
