On-site general maintenance work can be performed by the on-site duty personnel using the group users for routine equipment maintenance operations. In case of special circumstances or remote confirmation of on-site faults, the technical personnel need to guide the on-site duty personnel, use the user to log in, and open the maintenance center to the on-site monitoring machine. Remote control channel. Turn off all hidden shares in the monitor system, set to read-only mode for group users, and set to full control mode for group users. Install stand-alone anti-virus software and update the virus database regularly through remote connection. For monitors that access Ethernet, firewall software should be installed and the corresponding security rules defined. Install the built-in modem driver, establish a transport connection, and verify that the remote can be connected. Problem Analysis and Improvement At present, most of the hump-regulated wind power systems use air compressors with automatic loading and unloading functions for wind pressure compensation. In the fault state of the computer centralized control system, the local automatic condition of the air compressor is given by the trigger of the micro cabinet control panel. The air function can automatically compensate according to the pressure change of the wind source system, but the air compressor must be able to drive the cold water and electricity. The crew works. We take the start and stop cold water motor unit command in the air compressor start control circuit, so as to realize the automatic loading and unloading function of the air compressor by driving the cold water motor unit under the local automatic control state of the air compressor, as shown. The railway engineering air compressor drives the cold water motor unit through the pump control cabinet in the local automatic state. When the micro-cabinet water control cabinet microcomputer system crashes or the power supply fails, the wind pressure system cannot pass the sound and light alarm at the lower limit of the wind pressure, reminding the on-duty personnel to deal with it, thus causing the slippery vehicle to lose control. This situation is extremely dangerous. After the air compressor system of the first type air compressor is added, the air compressor determines the wind pressure lower limit through the pressure sensor in the case of the microcomputer system failure, and gives the cold water motor start command in advance, and starts the cold water through the water pump control cabinet. The motor realizes the cooling water circulation required for the air compressor to start, thereby realizing the local automatic loading and unloading function of the air compressor. The wind source monitoring and control system only sets a set of control power modules in the micro cabinet, providing micro cabinets, drive circuits and pump control cabinet control circuits. In the event of a system power failure or the failure of the power module, the pump control cabinet loses its working power and cannot work, resulting in the situation that the cold water motor unit can not automatically load and unload even if the air compressor is in the local automatic control state. Therefore, we have added a set of switching power supplies in the pump control cabinet, as shown. In this state, the power module does not participate in the work when the micro cabinet power module is working. When the power module fails, the output of the power module is turned on by the contact to control the control circuit in the pump control cabinet to ensure that the circuit is installed in the micro cabinet, and the power is supplied by the micro cabinet power module. Command control by the microcomputer. The alarm circuit will not work when the microcomputer crashes or the power fails. Therefore, we set up a set of circuits separately, by using the mains and gas tank electrical contact pressure upper and lower contacts, constructing an alarm circuit to ensure that sound and light alarms can be realized under any circumstances, thus reminding the on-duty personnel to deal with the wind in time to ensure the wind The pressure system pressure meets the requirements. diesel engine self priming sewage /trash pump Clean Water Pump,Clean Pump,Cleaning Pump Changhong Machinery Manufacture Co., Ltd. , http://www.dzpumpfluid.com
