As shown in Figure 1, in the present embodiment, this infrared temperature measurement system robot scaling equipment comprises black matrix 100, parameter setting circuit 101, heater circuit and refrigeration circuit.Wherein, parameter setting circuit 101 is for setting the target temperature of black matrix, and heater circuit is connected between black matrix and parameter setting circuit 101, and refrigeration circuit is also connected between black matrix and parameter setting circuit 101.Like this, by heater circuit or refrigeration circuit, just can black matrix be heated or be freezed, thereby make the temperature of black matrix 100 reach the target temperature setting, thereby infrared temperature measurement system is carried out to Registration.
In the present embodiment, the copper sheet material of the thick homogeneous of 6mm for the carrier of black matrix 100.The thermal conductivity of copper material is good, can make the temperature of heating plate spread rapidly, reduce Thermal Hysteresis Time, improves temperature-controlled precision, and guarantees that the temperature of black matrix is even.Meanwhile, black-body surface coating is selected special-purpose infrared developed infrared coating, and its normal reflection rate is greater than 0.92.In addition,, for the consideration of calibration scope and device volume, in the present embodiment, black matrix area is made to the square plate of 90 * 90mm size, but the utility model is not limited to this.
As shown in Figure 1, heater circuit comprises the first temperature sensor 102, first signal generator 103, the first on-off circuit 104 and heating member 105.Wherein, the first temperature sensor 102 is arranged on the surface of black matrix 100, for measuring the temperature of black matrix, and produces first temperature signal corresponding with blackbody temperature now.First signal generator 103 is connected with the first temperature sensor 102, and the first temperature signal that it can come according to the first temperature sensor 102 transmission and the target temperature of black matrix produce corresponding the first switch controlling signal.The first on-off circuit 104 is connected between first signal generator 103 and heating member 105, for carry out the power supply of correspondingly conducting or disconnection heating member 105 according to the first switch controlling signal of first signal generator 103 outputs.When the power turn-on of heating member 105, heating member 105 produces heats, by controlling the ON time of heating member 105 power supplys, can realize black matrix 100 is heated to target temperature.
Refrigeration circuit comprises second switch circuit 106 and cooling piece 107.Wherein, second switch circuit 106 is electrically connected between first signal generator 103 and cooling piece 107, for the target temperature of the first switch controlling signals of producing according to first signal generator 103 and black matrix, carrys out correspondingly conducting or disconnects the power supply of cooling piece.By controlling the ON time of heating member 105 power supplys, can realize by the temperature of black matrix 100 fast from increase to temperature be down to needed target temperature.
In the present embodiment, the first temperature sensor 102 adopts DS18B20 sensor, and Fig. 2 shows the circuit connection diagram of this temperature sensor.
As shown in Figure 2, the port one of DS18B20 is connected with the temperature acquisition port PA27 port of first signal generator 103, and port 2 is connected with 5V power supply, and port 3 is connected with ground.Wherein, between port one and port 2, be connected with resistance R 5,5V power supply just can play and draw effect the temperature signal of port one output like this, thereby guarantees reliability and the accuracy of temperature signal.

, it should be noted that, in other embodiment of the present utility model, first signal generator can also adopt other rational chips meanwhile, and such as comparer etc., the utility model is not limited to this.When using comparer, in the process that black matrix is heated, if lower than target temperature, exporting corresponding control signal, the temperature of black matrix controls the first on-off circuit 104 conductings, and make heating member 105 energisings, thereby realize the heating to black matrix.In the process that black matrix is lowered the temperature, if higher than target temperature, exporting corresponding control signal, the temperature of black matrix controls 106 conductings of second switch circuit, make cooling piece 107 energisings, thereby realize the fast cooling to black matrix.
As shown in Figure 1, when blackbody temperature reaches after target temperature, for alert, carry out in time the calibration operation of infrared temperature measurement system, the robot scaling equipment that the present embodiment provides also comprises the warning circuit 108 being connected with first signal generator 103.When blackbody temperature equals target temperature or with the difference of target temperature in allowed limits time, 103 of first signal generators produce also and send alarm signals to alarm signal 108, warning circuit 108 sends warning information according to the alarm signal receiving.
In the present embodiment, warning circuit is pointed out operating personnel by hummer sounding, and Fig. 3 shows the circuit diagram of this warning circuit.
As shown in Figure 3, in the warning circuit providing at the present embodiment, the base stage of triode Q5 is connected with the alarm signal port PA2 of first signal generator 103 by resistance R 16, and emitter-base bandgap grading is connected with ground, is connected with resistance R 17 between base stage and emitter-base bandgap grading.One end of hummer B1 is connected with the collector of triode Q5, and the other end is connected with 5V power supply by resistance R 15.
When blackbody temperature reaches target temperature, first signal generator 103 is the alarm signal to the base stage output high level of triode Q5 by alarm signal port PA2, thereby makes triode Q5 conducting.Triode Q5 conducting makes one end ground connection of hummer B1, and simultaneously the other end due to hummer B1 is connected with power supply, thus hummer B1 current flowing send the sound now, thus alert now can be carried out scale operation.
It should be noted that, in other embodiment of the present utility model, alarm electric current can also adopt other rational circuit forms, for example, when blackbody temperature reaches target temperature, by lighting light emitting diode, come alert to carry out in time the scale operation of infrared temperature measurement system, the utility model is not limited to this.
Again as shown in Figure 1, for the ease of operating personnel, the related data in calibration process is observed and analyzed, the robot scaling equipment that the present embodiment provides also includes display 109.Wherein, display 109 is connected with first signal generator 103, and it can show the target temperature setting by parameter setting circuit 101, the blackbody temperature can also displays temperature sensor 102 collecting.Like this, the analysis that operating personnel just can be correlated with according to these temperature datas, and according to analysis result, infrared temperature measurement system is debugged.In the present embodiment, display 109 adopts liquid crystal display, and it has Chinese display function, but the utility model is not limited to this.
