The utility model is characterized in that both the main collector and the secondary collector are SCMs; the temperature sensors adopt FTLD type temperature measuring cables, and are arranged on peripheric rings of the floating tops of oil tanks; the output ends of the temperature sensors are connected with the input end of the main collector or the secondary collector, the secondary collector is correspondingly connected to the main collector through a serial port module RS485 and the main collector is connected to a computer of the higher level through the light signal modulating module. The device collects the highest temperature of the oil tanks in the measurement 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 number of the temperature measuring cable is displayed and the measured result is simultaneously reported to the computer of the higher level.
Description
Affiliated technical field
The utility model provides a kind of tank body temperature monitoring prior-warning device, belongs to microcomputer automatic monitoring control technology field.
Background technology
The too high meeting of temperature of oil tank (gas tank) causes oil product volatilization, fire even blast.Existing fire detector only can be surveyed the fire that has taken place, can not forecast potential fire hazard; Traditional " point type " temperature sensor can only be measured " certain point " temperature, can not cover the monitoring target of wire, more is difficult to a certain surface temperature is monitored.At present, the environmental monitoring to oil tank still lacks advanced effective means.
The utility model content
The purpose of this utility model provides a kind of tank body temperature monitoring prior-warning device that can overcome the maximum temperature of above-mentioned defective, the floating top of online auto monitoring oil tank scope and have warning function.Its technical scheme is:
Comprise main collector, connect the alarm module, light signal modulation 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 FTLD type cable for measuring temperature, be installed on the oil tank Fu Ding border, its output termination master's collector or from the input end of collector, connect main collector from the collector correspondence through serial port module RS485, main collector connects a grade computing machine through the light signal modulation module.
Described tank body temperature monitoring prior-warning device, main collector, all adopt C8051F021 type single-chip microcomputer from collector, 20, the 21 pin module taking alarm of main collector, its 49 pin connects a grade computing machine through the light signal modulation module, and respectively 54～55 pin from collector connect main collector through serial port module RS485.
Described tank body temperature monitoring prior-warning device, the light signal modulation module comprises optical fiber modulation module and optical fiber socket module, wherein optical fiber socket module adopts the HFBR-1414 chip, connects higher level's computing machine through optical fiber, and its 2 pin connects+the 3.6V power supply, its 3 pin connects 7 pin of optical fiber modulation module through resistance R, the optical fiber modulation module adopts the PIC12C508/509 chip, and its 1 pin connects+the 3.6V power supply, and 2 pin, 3 pin connect crystal oscillating circuit, 5 pin connect 49 pin of main collector, 8 pin ground connection.
