Abstract
The invention discloses a multipoint temperature monitoring system comprising an embedded industrial control board, a multipoint temperature detection circuit, an alarm lamp module and a buzzer, wherein the embedded industrial control board is respectively connected with the multipoint temperature detection circuit, the alarm lamp module and the buzzer. The invention provides a two-channel (the channels can be extended to be more) temperature detection and display module which has wide applied range and strong generality, so that timing routing inspection or random inspection can be performed on two different nodes. A master-slave mode structural design is adopted, a plurality of digital temperature sensors are used for collecting multipoint temperatures and performing data processing, then alarm detection is performed, if the measured temperature values exceed the set upper limit value and the set lower limiting value, the buzzer gives an alarm, and an LED (Light Emitting Diode) lamp indicates specific alarm information.
Description
Technical field
The present invention relates to a kind of multipoint temperature monitoring system.
Background technology
Temperature monitoring system is typical case and system extremely widely during industrial or agricultural is used, and the temperature of different control objects is monitored have very strong application.For the variation that reduces temperature brings bad result to productive life, avoid local temperature too high, not only need with more accurate temperature sensor temperature to be carried out more effective measurement, also to carry out multimetering to the greenhouse, accomplish accurately to measure and stable control.
At present, existing 51 series monolithics and the digital temperature sensor of utilizing realized multi-route measuring temperature and based on the application of a railway digital temperature sensor thermometric of ARM platform, but stability and accuracy etc. are not very desirable.
Summary of the invention
The present invention provides a kind of multipoint temperature monitoring system for solving the problems of the technologies described above, and it has easy to use, and extensibility is stronger, can be widely used in needs and measure advantage in the system of temperature data.
To achieve these goals, the present invention adopts following technical scheme.
A kind of multipoint temperature monitoring system comprises embedded industrial control board, multi-point temp testing circuit, alarm lamp module and hummer module; Described embedded industrial control board is connected with multi-point temp testing circuit, alarm lamp module and hummer module respectively.
Further, multipoint temperature monitoring system of the present invention mainly is comprised of embedded industrial control board, multi-point temp testing circuit, alarm lamp module, hummer module, JTAG debugging interface and RS232 serial line interface etc. take 32 ARM7 microprocessor LPC2290 as core.
Wherein the multi-point temp testing circuit adopts 1-wire digital temperature sensor DS18B20, the alarm lamp module adopts 4 paths of LEDs lamps to indicate respectively passage 1 upper temperature limit, passage 1 lowest temperature, passage 2 upper temperature limits, passage 2 lowest temperatures to report to the police, and gives alarm as long as appearance arbitrary alarm condition is wherein rung by the hummer module.This system is by the RS232 serial port and host computer communicates and show, patrol and examine the operations such as control and set temperature bound arrange at the enterprising trip temperature of upper computer software.
Beneficial effect of the present invention: two passages (can expand to more hyperchannel) temperature detection and the display module of a kind of applied range, highly versatile are provided, can have carried out that timing is patrolled and examined or at random sampling observation to 2 different nodes.The design of employing primary and secondary structure, gathered multi-point temp and carried out the data processing by a plurality of digital temperature sensors, the check of then reporting to the police is if the measured temperature value surpasses the upper limit and the lower limit that sets, then hummer is done alarm, the concrete warning message of simultaneously LED lamp indication.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
The multipoint temperature monitoring system of present embodiment mainly is comprised of embedded industrial control board 1, multi-point temp testing circuit 2, alarm lamp module 3, hummer module 4, JTAG debugging interface and RS232 serial line interface etc. take 32 ARM7 microprocessor LPC2290 as core.
Wherein multi-point temp testing circuit 2 adopts 1-wire digital temperature sensor DS18B20, alarm lamp module 3 adopts 4 paths of LEDs lamps to indicate respectively passage 1 upper temperature limit, passage 1 lowest temperature, passage 2 upper temperature limits, passage 2 lowest temperatures to report to the police, and gives alarm as long as appearance arbitrary alarm condition is wherein rung by hummer module 4.This system communicates by RS232 serial port and host computer 5 and shows, patrols and examines the operations such as control and set temperature bound arrange at the enterprising trip temperature of host computer 5 softwares.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
