Referring to FIG. 3 to FIG. 8, the first embodiment of the present invention provides a method for providing different The temperature measurement device Z marked with color light spots includes: a temperature measurement device body 1, a signal control module 2, a signal supply module 3, a temperature sensing module 4, and a first color projection module 5 and a second color projection module 6 . In addition, the signal control module 2, the signal supply module 3, the temperature sensing module 4, the first color projection module 5 and the second color projection module 6 are all arranged inside the temperature measurement device body 1, and the signal The providing module 3 , the temperature sensing module 4 , the first color projection module 5 and the second color projection module 6 are all electrically connected to the signal control module 2 .

Furthermore, as shown in FIG. 3 , FIG. 4 , FIG. 7 and FIG. 8 , the temperature sensing module 4 is disposed on the temperature measuring device body 1 and is electrically connected to the signal control module 2 for The temperature of a target area T100 on an object to be measured T is measured within a temperature sensing range R (radiation heat source sensing range). In addition, the temperature sensing range R will extend along a temperature sensing optical axis A, and the thermal radiation (radiation heat source) generated by the target area T100 of the object T to be tested will be transmitted along the temperature sensing optical axis A to be heated by the temperature Received by the sensing module 4 . For example, the signal providing module 3 can be an automatic signal providing module or a manual signal providing module. In addition, the temperature sensing module 4 includes a temperature sensing chip 40 for sensing the radiation heat source, and the temperature sensing module 4 may be a non-contact temperature sensing module. However, the present invention is not limited to this example. It is worth noting that, as shown in FIG. 7 and FIG. 8 , when the temperature measuring device Z of the present invention is in use, the distance between the first color projection module 5 and the target area T100 of the object T is not equal to the first color projection module 5 . The distance between the two-color projection module 6 and the target area T100 of the object T to be tested.

Furthermore, as shown in FIG. 3 , FIG. 4 , FIG. 5 and FIG. 7 , the first color projection module 5 is disposed on the temperature measurement device body 1 and is electrically connected to the signal control module 2 for use in According to the control of the signal providing module 3 (cooperating with the signal control module 2 ), a first color light beam L1 is projected on the target area T100 of the object T to be tested. For example, the first color light beam L1 may be a red laser beam for providing a red spot mark. In addition, when the first color projection module 5 is used to project the first color light beam L1, the first color light beam L1 projected by the first color projection module 5 will follow a first projection The optical axis A1 is moved to form a first light spot mark M1 projected onto the target area T100 of the object T to be tested. However, the present invention is not limited to this example.

Furthermore, as shown in FIG. 3 , FIG. 4 , FIG. 6 and FIG. 8 , the second color projection module 6 is disposed on the temperature measurement device body 1 and is electrically connected to the signal control module 2 for use in According to the control of the signal providing module 3 (cooperating with the signal control module 2 ), a second color light beam L2 is projected on the target area T100 of the object T to be tested. For example, the second color beam L2 may be a green laser beam for providing a green spot mark. In addition, when the second color projection module 6 is used to project the second color light beam L2, the second color light beam L2 projected by the second color projection module 6 will move along a second projection optical axis A2 to A second light spot mark M2 projected onto the target area T100 of the object to be tested T is formed. It is worth noting that, since the user cannot get close to the test object T that is too high temperature, and the red light spot mark projected on the test object T that is too high is not obvious to the user's viewing (that is, The red light cannot allow the user to identify the object with higher temperature), so when the temperature of the object to be tested T is too high, the user can select the green light spot mark projected by the second color projection module 6 to clearly mark the object to be tested Object T's target area T100. In addition, the cost of "the second color projection module 6 for projecting the green laser beam" will be about 5 to 10 higher than the cost of "the first color projection module 5 for projecting the red laser beam" times. However, the present invention is not limited to this example.

It is worth noting that, as shown in FIG. 5 and FIG. 6 , the first projection optical axis A1 and the temperature sensing optical axis A are inclined to each other and coincide with a first coincidence point P1 (that is, the first focus point, as shown in FIG. 5 ). shown), the second projection optical axis A2 and the temperature sensing optical axis A are inclined to each other and coincide with a second coincidence point P2 (that is, the second focus point, as shown in FIG. 6 ), and the first coincidence point P1 is separated from the temperature The distance of the sensing module 4 is smaller than the distance between the second coincidence point P2 and the temperature sensing module 4 . For example, as shown in FIG. 5 , when the first color light beam L1 projected by the first color projection module 5 passes through the first coincidence point P1 , the first color light beam L1 will completely fall on the first coincidence point P1 Within the temperature sensing range R (or in other words, the light spot generated by the first color light beam L1 on the first coincidence point P1 will completely fall within the temperature sensing range R) covered area). As shown in FIG. 6 , when the second color light beam L2 projected by the second color projection module 6 passes through the second coincidence point P2, the second color light beam L2 will completely fall on the temperature sensing at the second coincidence point P2 (or in other words, the light spot generated by the second color light beam L2 on the second coincidence point P2 will completely fall within the area covered by the temperature sensing range R). In addition, the first color light beam L1 projected by the first color projection module 5 has a first field of view (Field of View, FOV for short), and the second color light beam L2 projected by the second color projection module 6 There is a second angle of view, and the first angle of view of the first color light beam L1 is greater than the second angle of view of the second color light beam L2. However, the present invention is not limited to this example.

In addition, the distance sensing chip 31 can provide a distance information S1 to the signal control module 2 according to the distance between the temperature measuring device Z and the target area T100 of the object T (that is, through the distance sensing chip 31 to measure The distance between the temperature measuring device Z and the target area T100 of the object to be measured T), and the signal providing module 3 (cooperating with the signal control module 2) can turn on the first color projection module 5 and the second color according to the distance information S1 One of the two projection modules 6.

For example, when the ratio (D/S ratio) of the measurement distance (distance) to the measurement area (spotsize) of the temperature measurement device Z is less than 10, and the temperature measurement device Z is far from the target area T100 of the object T to be measured When the distance is less than or equal to 1 meter, the first color projection module 5 can be turned on through the control of the signal supply module 3 (cooperating with the signal control module 2), thereby projecting the first light spot mark M1 to be tested object T on the target area T100. In addition, when the D/S ratio of the temperature measuring device Z is less than 10, and the distance between the temperature measuring device Z and the target area T100 of the object to be measured T is greater than 1 meter, the second color projection module 6 can provide a signal through the The module 3 (cooperating with the control of the signal control module 2 ) is turned on, thereby projecting the second light spot mark M2 on the target area T100 of the object T to be tested. In this way, the temperature sensing module 4 can selectively according to the projected position of the first light spot mark M1 or the second light spot mark M2 set to measure the temperature of the target area T100 of the object to be tested T. However, the present invention is not limited to this example.

For example, when the D/S ratio of the temperature measuring device Z is between 20 and 30, and the distance between the temperature measuring device Z and the target area T100 of the object T is less than or equal to 2 meters, the first The color projection module 5 can be turned on through the control of the signal supply module 3 (cooperating with the signal control module 2 ), thereby projecting the first light spot mark M1 on the target area T100 of the object T to be tested. In addition, when the D/S ratio of the temperature measuring device Z is between 20 and 30, and the distance between the temperature measuring device Z and the target area T100 of the object T is greater than 2 meters, the second color projection module 6 can be turned on through the control of the signal providing module 3 (cooperating with the signal control module 2 ), thereby projecting the second light spot mark M2 on the target area T100 of the object T to be tested. In this way, the temperature sensing module 4 can selectively measure the temperature of the target area T100 of the object to be tested T according to the projected position of the first light spot mark M1 or the second light spot mark M2 . However, the present invention is not limited to this example.

For example, when the D/S ratio of the temperature measuring device Z is greater than 50, and the distance between the temperature measuring device Z and the target area T100 of the object T is less than or equal to 3 meters, the first color projection module 5 It can be turned on through the control of the signal providing module 3 (cooperating with the signal control module 2 ) to project the first light spot mark M1 on the target area T100 of the object T to be tested. In addition, when the D/S ratio of the temperature measuring device Z is greater than 50, and the distance between the temperature measuring device Z and the target area T100 of the object T is greater than 3 meters, the second color projection module 6 can provide a signal through the The module 3 (in conjunction with the control of the signal control module 2 ) is turned on to project the second light spot mark M2 on the target area T100 of the object T to be tested. In this way, the temperature sensing module 4 can selectively measure the temperature of the target area T100 of the object to be tested T according to the projected position of the first light spot mark M1 or the second light spot mark M2 . However, the present invention is not limited to this example.

Furthermore, the temperature sensing chip 32 can provide a temperature information S2 according to the temperature of the target area T100 of the object under test T (that is, the temperature sensor chip 32 is used to measure the temperature of the target area T100 of the object under test T). temperature), and the signal providing module 3 (cooperating with the signal control module 2) can turn on one of the first color projection module 5 and the second color projection module 6 according to the temperature information S2.

For example, when the temperature of the target area T100 of the object to be tested T is less than or equal to 1000°C, the first color projection module 5 can be turned on through the control of the signal providing module 3 (cooperating with the signal control module 2 ), Thereby, the first light spot mark M1 is projected on the target area T100 of the object T to be tested. In addition, when the temperature of the target area T100 of the object to be tested T is greater than 1000°C, the second color projection module 6 can be turned on through the control of the signal providing module 3 (cooperating with the signal control module 2 ), thereby projecting The second light spot mark M2 is placed on the target area T100 of the object T to be tested. In this way, the temperature sensing module 4 can selectively measure the temperature of the target area T100 of the object to be tested T according to the projected position of the first light spot mark M1 or the second light spot mark M2 . However, the present invention is not limited to this example.

It should be noted that the temperature sensing chip 32 of the signal providing module 3 and the temperature sensing chip 40 of the temperature sensing module 4 may be different temperature sensing chips or the same temperature sensing chip. For example, the temperature sensing chip 32 of the signal providing module 3 and the temperature sensing chip 40 of the temperature sensing module 4 can operate separately, or the temperature sensing chip 32 of the signal providing module 3 can be temperature-sensed The temperature sensing chip 40 of the measuring module 4 is replaced (that is, the temperature sensing chip 32 of the signal providing module 3 can be omitted).
