Abstract
The utility model provides a monitoring and early warning device for furnace temperature, which comprises a main collector, a warning module which is connected with the main collector, a secondary collector and a plurality of temperature sensors. The utility model is characterized in that both the main collector and the secondary collector are SCMs, the temperature sensors adopt CTTC type temperature-measuring cables which are wound around the casings of gasifying furnace containers, the output ends of the temperature sensors are connected with the input end of the main collector or the secondary collector and the secondary collector is connected with the main collector through a serial port module RS485. The device collects the highest temperature of the gasifying furnaces in the measuring range by the temperature sensors, and outputs the information to the main collector or the secondary collector. Datum is transmitted by the secondary collector to the main collector through the serial port module RS485. and the main collector carries out data processing and stores the datum in a memory. Alarm can be carried out according to processed result, the numbers of the temperature measuring cables are displayed and the measured result is simultaneously reported to a computer of the higher level through an RS232 interface.
Description
Affiliated technical field
The utility model provides a kind of furnace body temperature monitoring and warning device, belongs to microcomputer automatic monitoring control technology field.
Background technology
When the refractory brick of gasification furnace has the crack, can form heat spot.Monitor each regional temperature of gasification furnace surface in real time, can detect the temperature overheating of zonule, in order to avoid gasification furnace damages because of local overheating.Prior art can only be measured the temperature of isolated point, is difficult to realize large-range measuring, can not simply determine the maximum temperature point.
The utility model content
The purpose of this utility model provides a kind of furnace body temperature monitoring and warning device that can overcome above-mentioned defective, online auto monitoring gasification furnace case surface temperature and have warning function.Its technical scheme is:
Comprise main collector, connect the alarm module of main collector, from collector and some temperature sensors, it is characterized in that: main collector, be single-chip microcomputer from collector, temperature sensor adopts CTTC type cable for measuring temperature, be wrapped on the gasification furnace shell of tank, its output termination master's collector or from the input end of collector, from collector through serial port module RS485 and main collector and connect.
Described furnace body temperature monitoring and warning device, main collector, all adopt C8051F021 type single-chip microcomputer from collector, 20, the 21 pin module taking alarm of main collector, 48,49 pin connect a grade computing machine through serial port module RS232, and respectively 54～55 pin from collector connect main collector through serial port module RS485.
Described furnace body temperature monitoring and warning device, main collector and respectively connect 8 temperature sensors at most from collector.
Its principle of work is: temperature sensor adopts CTTC type cable for measuring temperature, be wrapped on the gasification furnace shell of tank, measurement range can cover the surface of whole tested gasification furnace shell, can measure the maximum temperature of range to be monitored continuously in real time, the amplitude of temperature mutation can not only be measured, and the zone of temperature mutation can be measured.Body of heater maximum temperature in institute's survey scope is outputed to main collector or from the input end of collector as many cable for measuring temperature of temperature sensor, from collector the conversion of signals of gathering is become digital signal after serial port module RS485 is sent to main collector, temperature data is handled and is deposited in on-chip memory by main collector, can carry out early warning or warning according to result, and demonstrate the numbering of cable for measuring temperature, simultaneously can be with measurement report higher level computing machine.Present technique realizes the online auto monitoring of furnace body temperature by simple line, scents a hidden danger, and in time takes measures, and take precautions against, and then the safety of assurance gasification furnace is normally moved.
