Array type multipoint temperature monitoring system

Abstract

The present invention discloses a array type multi-point temperature monitoring system, including a plurality of monitoring devices, each of which is connected with a temperature sensor measuringline cable of 1000m at longest, each measuringline cable may drive at most 50 of single bus temperature sensors, the temperature sensor is capable of detecting the temperature information of the position where the temperature sensor locating, and the temperature data is transmitted to the monitoring device with a singlechip as a control kernel through a single bus data transmission protocol. The monitoring device has functions of data display, data memory, parameter enactment, overrun alarm, data transmission and the like. The monitoring devices combine a network through RS-485 communication bus, and are connected to a computer host by RS-485 / RS-232 protocol converters, and RS-232 bus to form the array type multi-point temperature monitoring system. The array type multi-point temperature monitoring system is used for situation with a large area multi-point temperature monitoring requirement.

Description

technical field [0001] The invention relates to the field of temperature monitoring systems, and is an array-type multi-point temperature monitoring system with a large measurement range and a large number of measurement points, which is applied in storage, cold storage, and temperature field monitoring of coal mine freezing method sinking wells. Background technique [0002] With the continuous development of industrial production safety requirements, there are more and more occasions that need to monitor temperature. Traditional temperature inspection instruments have limited measurement points, and the distance from the measurement point to the instrument is strictly limited. It is difficult to meet the large coverage of temperature measurement points. application occasions. The emerging distributed optical fiber temperature monitoring method provides a good solution for large-area continuous multi-point temperature monitoring, but its high price prohibits most simple tem...

[0002] With the continuous development of industrial production safety requirements, there are more and more occasions that need to monitor temperature. Traditional temperature inspection instruments have limited measurement points, and the distance from the measurement point to the instrument is strictly limited. It is difficult to meet the large coverage of temperature measurement points. Applications

The emergence of the emerging distributed optical fiber temperature monitoring method provides a good solution for large-area continuous multi-point temperature monitoring, but its high price prohibits most simple temperature monitoring needs.
