Emulsion pump station control host machine

Abstract

The invention relates to an emulsion pump station control host machine. A CPU (Central Processing Unit) module in the control host machine is used for completing state inspection, fault inquiry, parameter setting, time setting, user management setting and parameter shielding setting; system halting is avoided by using a watchdog module; a clock module is used for providing a clock signal for a system; a communication state display module is used for displaying whether the current communication is in receiving or transmitting state; a serial port expansion module is used for expanding a serial port resource of the CPU module into two paths; an RS485 conversion module is used for completing communication between the control host machine and each control branch machine; an RS232 conversion module is used for completing communication between the control host machine and a display screen; an external switch control module and an internal key control module are used for completing system operation by keys; and an emergency stop module is used for realizing machine halt under an emergency condition. The control host machine continuously communicates with each control branch machine to complete the communication function of the system, has the characteristics of convenience of operation, reliable performance and perfect function, and can be used for well realizing control over an emulsion pump station.

Description

technical field [0001] The invention relates to a control host of an emulsion pumping station, which is especially suitable for the control of a large-flow emulsion pumping station as comprehensive parameter processing equipment, and belongs to the related technical field of emulsion pumping station control. Background technique [0002] At present, the control system and monitoring system of the emulsion pumping station used by most small and medium-sized coal mines in China are not perfect. The emulsion pumping station of many coal mines does not have a control system and a monitoring system, and only consists of two emulsion pumps and an emulsion tank. When working, one is used as a backup, the hydraulic pressure is small, the flow is small, the pulsation is large, the system is unstable, and failures often occur during use, which seriously affects the safe production of the working face. The large domestic mines and the emulsion pumping stations used abroad are emulsion ...

AI Technical Summary

Problems solved by technology

The maintenance cost of electrical equipment and the cost of equipment spare parts are relatively high, which is not conducive to long-term use

Especially after a period of use, the failure rate increases and the amount of maintenance is large. Some parts cannot be repaired and can only be replaced after being damaged. Separate parts are more expensive and the order cycle is long, which increases the cost of coal mining and affects the normal production of coal mining; At the same time, the control system is affected by the pumping station motor, emulsion concentration, emulsified oil and equipment structure of the foreign system. The pumping station liquid supply equipment has various models and specifications. The foreign electronic control system cannot be well used for domestic liquid supply equipment. easy to promote
