The utility model is characterized in that the one-parameter of the temperature and the one-parameter of the vibration are mutually separated to be set, which can realize the control for the warning and the shutting-down. The device of the utility model can also set the comprehensive status of the corresponding combination of the temperature and the vibration, which can realize the warning and the shutting-down. The utility model can display and record the parameter of the temperature and the vibration at any moment. The circuit of the utility model is simple and reliable. The device of the utility model can be widely used for monitoring the vibration and the temperature rise generated by sport machines.
Description
The utility model relates to the device that a kind of vibration and temperature that is used for movable machinery shows and report to the police.
The vibration of existing movable machinery and temperature, the general one-parameter that adopts shows, report to the police, be that temperature and vibration realizing are given respectively, transfinite and report to the police separately, fail to temperature, vibrate the realization integrated alarm of two parameter correlations, though vibration and temperature value all do not reach alarming value separately, yet because both have interrelated, when both numerical value reach a certain value, can destroy movable machinery, the independent alarming value of for example a certain movable machinery is 90 ℃, and the vibration amplitude value is reported to the police and is 0.09mm, yet all can run into such situation in the actual motion, arriving 87 ℃ as temperature, when corresponding amplitude is 0.08mm, but is a dangerous values to this movable machinery, need monitor, thereby need monitor alarm is carried out in the vibration of movable machinery and the overall target of temperature correlation, existing apparatus can only be realized vibration in the market, the temperature one-parameter shows, report to the police and cut off the electricity supply, circuit is also complicated like this, reliability is low, and is not easy to operation.
The purpose of this utility model provides a vibration and temperature displaying alarm can realize that temperature, vibration are respectively given to movable machinery, realize the one-parameter displayed record, report to the police and cut off the electricity supply, can realize again vibrating, the comprehensive state of temperature correlation, report to the police and cut off the electricity supply.
The technical solution of the utility model is that device is made up of vibration-measuring sensor, temperature sensor, amplifier, comparer, A/D converter, Display and Alarm Circuit, the control circuit of cutting off the electricity supply etc., temperature sensor, vibration-measuring sensor connect the display register through separately amplifier, A/D converter, display driver circuit respectively, show, the vibration amplitude and the temperature value of the reality of record movable machinery; Temperature sensor and vibration-measuring sensor are exported behind amplifier and are connected to corresponding temperature respectively, vibration alarming is set comparer, temperature, vibration are stopped and are set comparer, the output of these comparers connects the warning driving circuit respectively, (parking) control circuit of cutting off the electricity supply, and realizes the vibration of movable machinery, one-parameter warning and the parking that temperature is separated separately; Temperature sensor is exported behind amplifier and also is connected to comprehensive state temperature alarming setting comparer, the comprehensive state temperature is stopped and is set comparer, vibration-measuring sensor is exported behind amplifier and also is connected to comprehensive state vibration alarming setting comparer, the comprehensive state vibration is stopped and is set comparer, both corresponding comprehensive state temperature alarmings are set and vibration alarming is set comparer output connection warning driving circuit after AND circuit, both corresponding comprehensive state temperature parkings are set and vibration is stopped, and the setting comparer is exported through being connected parking control circuit with door, realizes the warning and the parking of comprehensive state.
The utility model embodiment further narrates in conjunction with the accompanying drawings.
Figure is vibration and temperature displaying alarm schematic circuit.
Shown in figure, this device is by temperature sensor, vibration transducer, amplifier, comparer, A/D converter, Display and Alarm Circuit, the compositions such as control circuit of cutting off the electricity supply, temperature sensor is that AD590 film platinum resistor and compensated line are formed, when temperature range is 0～100 ℃, output voltage is 0～5V, vibration-measuring sensor adopts the 3CB-1 difference transformer type vibration transducer of institute of water section, it is output as voltage signal, this signal magnitude is directly proportional with the vibration amplitude of corresponding movable machinery, temperature sensor, vibration-measuring sensor divides in addition the amplifier AMP1 through separately, AMP2, A/D converter 1 and 2, display driver circuit, connect actual amplitude and temperature value that display shows movable machinery, temperature sensor, vibration-measuring sensor is exported connecting band temperature respectively behind amplifier, the comparator C OMP1 that amplitude is reported to the police and stopped and set, COMP5, COMP2, COMP6, Vref1 is an alarm temperature respective settings current potential, Vref5 is the corresponding set amplitude of warning amplitude, Vref2, Vref6 is respectively the parking temperature and the parking amplitude is set current potential accordingly, one actual temperature and vibration amplitude value when movable machinery arrives the warning of setting, the parking potential value, the output of comparer drives warning circuit and parking control circuit, realize overtemperature, surpass the warning and the parking of amplitude, the vibration of realization movable machinery is reported to the police and is stopped with the one-parameter that temperature is separated separately, in actual motion, can run into such situation, temperature and amplitude all do not reach the warning of single setting, the parking value, yet both respective combination have but been destroyed movable machinery, in other words, there are a temperature and amplitude combination that a comprehensive index value is arranged to each movable machinery, every machine is different, can give first test, set then, therefore the utility model temperature sensor and vibration-measuring sensor meet the temperature alarming setting comparator C OMP3 parking setting comparator C OMP4 of comprehensive state respectively after amplifying, the vibration alarming of comprehensive state is set comparator C OMP7, stop and set comparator C OMP8, COMP3 and COMP7 output warp and door Y1, or door H1 drives warning circuit, the realization comprehensive state is reported to the police, COMP4 and COMP8 output warp and door Y2, or door H1 drives parking control circuit, the warning and the parking of the comprehensive state when temperature and amplitude arrive a certain value have been realized, amplifier AMP1, AMP2 all selects ICL7650 for use, comparator C OMP1～COMP8 adopts four combinations of LM339, parking control circuit is made up of triode T and relay J, and the contact of relay is serially connected in the power circuit.
It is to carry out on-line testing on 9 meters, 14 meters the large axial flow fan that the utility model has been installed in diameter, reached and given fixed requirement, circuit is simple and reliable, it can be widely used in vibration that movable machinery produces and owing to the temperature rise of reasons such as friction generation is monitored, can show, write down the temperature rise process of vibration parameters and lubricating oil and movement parts at any time, can realize monitoring to temperature, vibration one-parameter respectively, can realize monitoring to both comprehensive states again, realize reporting to the police and stopping.
