Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0015] refer to Figure 1-3 , Install a wireless temperature transmitter with a WIA-PA wireless communication module at the entrance of the sealed air duct of the coal mill, install a WIA-PA intelligent wireless gateway in the local control cabinet of the coal mill, and wirelessly access three coal mills The temperature signal of the grinding roller, and monitor, manage and maintain the equipment in the WIA-PA network. The wireless gateway converts the temperature signal of the WIA-PA wireless access into the Modbus TCP protocol and transmits the data to the main control DCS through the Ethernet interface. Modbus communication card CM card, the DCS host computer can ...

Abstract

The invention discloses a coal mill grinding roller temperature measurement system based on wireless transmission. The coal mill grinding roller temperature measurement system comprises a wireless temperature acquisition module which is used for temperature acquisition and is provided with a WIA-PA wireless communication module, a Modbus TCP industrial network system of a master control DCS, a WIA-PA intelligent wireless gateway which is responsible for protocol conversion and data mapping of a WIA-PA network and a Modbus TCP industrial network system, and a wireless debugging terminal which is used for on-site opening, debugging, maintenance and on-line configuration. The system can greatly reduce the cable consumption, reduces the construction manpower, reduces the inspection intensity,saves the production cost, and guarantees the continuous, stable and efficient operation of production.

Description

technical field [0001] The invention relates to the technical field of power plant equipment, in particular to a coal mill grinding roller temperature measurement system based on wireless transmission. Background technique [0002] A power plant refers to a power plant that converts some form of raw energy into electrical energy for fixed facilities or transportation, such as thermal power, hydraulic power, steam, diesel or nuclear power plants, etc. The coal mill crushes and grinds coal into Coal pulverized machinery, it is an important auxiliary equipment for pulverized coal furnace. There are vertical mills, high-pressure suspension roller mills, medium-speed micro-powder mills, overpressure trapezoidal mills, Raymond mills and other models, which are commonly used equipment in power plants. In order to better understand the working status of coal mills, it is necessary to collect coal mills For the temperature of the grinding roller, the traditional method of temperatur...
