Abstract
The invention discloses a programmable temperature testing system that includes one or plural temperature sensor, programmable controller, and touch screen. The analog quantity output by temperature sensor would transmit to the input unit of the programmable controller that is connecting to touch screen by RS-232 cable through temperature device. When the temperature exceeding the upper limit, the temperature value would be displayed on touch screen and display alarming/stopping message, and send alarming/stopping signal to host computer. The host computer would take cooling/braking process. The advantages of the invention are that it saves cost, has high reliability and is easy to operate.

Technical field
The present invention relates to a kind of genset temperature control system, particularly relate to a kind of programmable temp testing controlling system.
Background technology
Genset is a kind of power equipment of a large amount of heatings, parts such as stator coil, thrust bearing, guide bearing can produce a large amount of heat energy, as detect and control the temperature rise of each critical piece of genset untimelyly, this not only can cause the unit fault, burn out genset, even also can cause disaster accident, power plant's property and personnel's life security are constituted significant threat.Therefore Detection ﹠ Controling systems such as unit temperature, pressure, position, electric weight have all been set up in each power house at present, but too dispersion, cost that existing system has are higher, and then information indicating that has and parameter are provided with directly perceived inadequately, convenient.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of programmable temp testing controlling system is provided, this system adopts the procedure parameter continuous monitoring of concentrating to the measuring point that some physical locations in the main building are concentrated relatively, quantity is many, not only can save cost, and the reliability height, the operation intuitive and convenient.
Goal of the invention of the present invention is achieved through the following technical solutions: programmable temp testing controlling system, comprise one or more temperature sensors, Programmable Logic Controller, touch-screen, the analog quantity of temperature sensor output is connected to the input block of Programmable Logic Controller through temperature measurement module, and Programmable Logic Controller is connected and swap data by the RS-232 cable with touch-screen.Wherein, the data owner of exchange will comprise ceiling temperature, upward ceiling temperature, thermometric line broken circuit detect instruction, the thermometric line short detects instruction.
When the measuring point temperature surpassed ceiling temperature, Programmable Logic Controller sent the warning message in the viewing area of touch-screen, and sends alerting signal by its output unit to host computer, takes cooling measure by host computer.
When the measuring point temperature surpassed last ceiling temperature, Programmable Logic Controller sent the shutdown message in the viewing area of touch-screen, and sends stopping signal by its output unit to host computer, takes the shutdown measure by host computer.
Described temperature measurement module comprises an A/D converter, a thermometric line broken circuit/short-circuit detecting unit, A/D converter, thermometric line broken circuit/short-circuit detecting unit all are connected with temperature sensor, thermometric line broken circuit/the output of short-circuit detecting unit is connected with the input of A/D converter, and the function conversion of temperature measurement module is by Controlled by Programmable Controller.
Temperature sensor is a thermo-sensitive resistor.
The course of work of the present invention roughly is: temperature sensor is placed on the place that stator coil etc. need carry out temperature monitoring and control, the output of temperature sensor is connected to the A/D converter of temperature measurement module, the analog quantity that A/D converter is exported temperature sensor is converted to the discernible digital quantity of Programmable Logic Controller and is input to the input block of Programmable Logic Controller, the CPU (central processing unit) of Programmable Logic Controller under programmed control, read in these digital quantities and with the ceiling temperature that sets in advance, last ceiling temperature is compared, if the Current Temperatures of certain point for measuring temperature is higher than its default ceiling temperature, Programmable Logic Controller is sent to this temperature value on the one hand and shows on the touch-screen and prompting warning message, by its output unit alerting signal is sent to host computer on the other hand, unit is implemented cooling control by host computer.When if the Current Temperatures of certain point for measuring temperature is higher than its default last ceiling temperature; Programmable Logic Controller is sent to this temperature value on the one hand and shows on the touch-screen and prompting shutdown message; also stopping signal is sent to host computer on the other hand, unit is implemented to shut down control by host computer by its output unit.
Operating personnel can be by touch-screen one by one or the ceiling temperature of each point for measuring temperature of batch setting, go up ceiling temperature, and its setting up procedure can carry out according to the prompting on the touch-screen, the operation intuitive and convenient.
Operating personnel can assign other instruction by touch-screen, and as detecting whether the thermometric circuit opens circuit or short circuit etc., its operating process can be carried out according to the prompting on the touch-screen, operates same intuitive and convenient.
Advantage of the present invention is: can adopt the procedure parameter continuous monitoring of concentrating to the measuring point that some physical locations in the main building are concentrated relatively, quantity is many, not only can save cost, and reliability height, operation intuitive and convenient.
