Abstract
The shaft temp. measuring method uses a measuring system which is composed of single-chip processor as main part, sensor, preamplifier, main control board, panel keys, power supply, output control circuit and display, and features using the method of the combination of fixed-point and circulating detections to judge if shaft temp. is normal accuratelyand quickly. The temp. threshold may be modified at any time.
Description
The present invention relates to a kind of temperature detection-control technology, refer to a kind of shaft temperature measuring and controlling method especially.
Have the shaft temperature measuring and controlling technology now and realize that general single channel or multi way temperature show or controlling alarm, owing to exist the observing and controlling mode single, temperature threshold values is difficult to arbitrarily deficiency such as setting and change, has influenced the observing and controlling precision, has limited range of application.
The object of the present invention is to provide a kind of shaft temperature measuring and controlling method, can finish touring demonstration and overload alarm and the control output function that transfinites of detecting, can be provided with and change each road temperature threshold values according to actual needs arbitrarily again, also usable temp and temperature rise dual mode carry out temperature control, and touring transfinite channel number and the temperature value of showing, preserve the peak value that transfinites.
Order of the present invention has to be achieved in that with the single chip circuit to be the shaft temperature measuring and controlling system that main body constitutes, and detects axle temperature through following process:
The power down operations mode is set, makes single chip circuit be operated in the power down operations state:
Each access door limit value is set, and goes the rounds to detect.
Touring detection should be according to the following steps:
(1) regularly constant is set;
(2) the axle temperature value digitizing that will record by temperature sensor, and with threshold value relatively, multichannel transfinites in this way, then touring alarm indication: transfinite the alarm indication of then fixing a point, and show transfinite channel number and temperature rise value as single channel;
(3) warning is removed and is detected;
(4) revise temperature threshold values, and channel number behind the display update and passage temperature rise value;
(5) detect timing index, set is then removed;
(6) detect next road.
Use shaft temperature measuring and controlling technology provided by the present invention, can be accurately and whether the axle temperature that forms a prompt judgement is normal, thus carrying out normally touring detection alarm shows, and keep abnormality, every road threshold value to revise at any time in the course of the work and do not influence and normally patrol and examine; During multiple alarm, can go the rounds to show transfinite passage and temperature rise value, shaft temperature measuring and controlling is convenient, observing and controlling precision height.
The contrast accompanying drawing is further set forth the present invention below.
Fig. 1 is for realizing circuit theory synoptic diagram of the present invention.
The shaft temperature measuring and controlling circuit that Fig. 1 provides partly is made up of sensor S, pre-amplification circuit A, master control borad, panel operating key, power supply, output circuit and display circuit L1-L4 etc.Sensor AD590, pre-amplification circuit is common amplifying circuit, ADC0816 is 16 road A/D converters, master control borad is by single-chip microcomputer U1(80C31BH), address latch U2(74LS373) and memory under program U3(2716) etc. the single chip circuit formed be that main body is finished control function, single-chip microcomputer is operated in power-down mode, state is by testing circuit U4(monostable circuit 74HC123) power supply is detected controls, reserve battery can have a power failure or off-mode under keep in the U1 RAM value not lose; Single-chip microcomputer U1 is connected to address decoder U6(74LS138), channel number and temperature/temperature rise display L1-L4 is through latch U7, U8, U9, U10(74LS373) finish demonstration work, address strobe is finished by U6.U1 is provided with the output W1 that reports to the police, stop output W2, temperature patrol inspection K1, warning temperature rise K2, parking temperature rise K3, data input K4, reset after transfiniting K5 and patrol apparent/show panel operating key input port such as K6 surely.As functional switch being placed " warning temperature rise " or " parking temperature rise " shelves, through " patrolling apparent/fixed showing " key, the passage that selection must be revised is through latch U11, U12(74LS373 again), can import temperature rise value by the plucking number sign switch B1～B4 on the panel.Circuit also has the fixed point selection function, by the U14(R-S trigger) through heuristicimal counter U13(74LS293) be connected in single-chip microcomputer U1.Above-mentioned shaft temperature measuring and controlling circuit working flow process is as shown in the table:
Claims (5)
