New description: [New technical field] This creation system--species fine system' especially refers to the side system with multiple single-point temperature sensing heads, which can have the temperature of the entire copper area, It is affected by external noise interference, non-contact sensing speed and simple device. [Prior Art] With the development of modern industrial production towards high speed and automation, the method of manual measurement and monitoring of temperature in the production process has been gradually replaced by non-contact thermal sensing n. Its ability to automatically maintain the quality of the product (quality control by temperature) is very important for the automation industry. For example: the high temperature furnace temperature test of Sinosteel Steelmaking Plant, motor machinery (such as potential fault test of transformer on the wiring pole of Taiwan electric wheel, such as the regional power outage of A thief), must quickly and automatically prevent and detect fire, semiconductor process Temperature monitoring, military weapon system development, influenza prevention (such as H1N1 flu), human body temperature safety testing at airports, etc. Conventional temperature sensors have the following disadvantages: [1] The temperature of the entire area cannot be made. Current temperature sensors are generally independent thermal sensors' can only measure single point temperature. Take infrared temperature sensor as an example. Suppose the patient's forehead is divided into ten areas, and only seven of them. The temperature in the area reaches the fever temperature. The other three areas are still between the acceptable body temperature and the fever temperature limit (in fact, the patient is in a state of fever). Once the measured position is in the two areas, it is possible Misdiagnosis of the patient (assumed to be infected with 3 M395825 H1N1) and may cause a pandemic. [2] The device is complicated. Of course, there are infrared thermometers on the market (such as the human body temperature safety detection device at the airport), which can be used for instant surface type (the whole body can sense) temperature sensing, but the output_specific signal is usually very weak and needs to be used. Magnification n amplification, and then _ than / digital conversion of the riding ship for further processing 'to carry out temperature measurement' increases the complexity of the circuit, and there is a large / dish measurement error, affecting the effect of temperature measurement, so In addition, the problem arises that the device is complicated (relatively expensive and difficult to maintain). In view of this, it is necessary to develop a technique that can solve the above disadvantages. [New content] The purpose of the novel is to provide a detection system with a plurality of single-point temperature sensing heads, which can detect the entire area, is free from external noise interference, and has a non-contact sensing speed. Simple device function. In particular, the problems to be solved by the present invention include the inability to detect the temperature of the entire area and the complexity of the device. The technical means for solving the above problems is to provide a detection system with a plurality of single-point temperature sensing heads, comprising: a plurality of single-point temperature sensing heads for respectively sensing a plurality of objects on a test object The thermal signal sent by the thermal sensing area has a plurality of boundary points in each of the thermal sensing regions. The thermal signal includes a thermal signal to be tested emitted by the detecting region enclosed by the plurality of boundary points, and the plurality of boundaries. a thermal noise signal emitted from a noise area surrounded by a point; a plurality of thermal signal accommodation devices are respectively located between the corresponding single point type, θ 4 M395825 degree sensing head and the thermal sensing area, Each of the _ thermal signal operation devices includes a focusing portion and a thermal treading portion; the focusing portion is focused by the heat signal and is incident on the thermal absorbing portion; the miscellaneous contact portion has an overview point, A plurality of channel points include (4) a thermal signal channel and a plurality of boundary points surrounded by the n-threshold to be tested, * for the passage of the miscellaneous signal, and can be irradiated to the corresponding single-time temperature sense _; The hot noise blocking surface surrounded by slave points and the plural boundaries Corresponding to the noise zone surrounded by the limit point, and used to block the thermal noise signal; a discriminating component is connected to the plurality of single-point temperature sensing heads at the same time, and has a set of thermal signal standard values, when a plurality of singles The hot sensor signal sensed by the point temperature sensing head is transmitted to the discriminating element for comparison with the set of thermal signal standard values, and if it is consistent, the object to be tested is qualified; if not, the judging object is determined; The sample to be tested failed. The above objects and advantages of the present invention are not limited by the detailed description of the selected embodiments described below and the accompanying drawings. The following examples are described in detail with reference to the drawings: [Embodiment] This creation is a detection system with a plurality of single-point temperature sensing heads. 'Refer to the first, first and third figures. The method includes: a plurality of single-point temperature sensing heads 10 for sensing a heat signal 911 generated by a plurality of thermal sensing regions 91 on a test object 90, each of the thermal sensing regions 91 The plurality of limit points 91〇, the heat signal 911 includes the hot to-be-tested signal emitted by the plurality of 5 M395825 limit points 91〇 surrounded by the test area 91A, and the noise boundary of the plurality of limit points 91〇_9m The hot noise 911B is sent; a plurality of thermal axising devices 2G are disposed between the temperature sensing head 1G and the thermal sensing area %, and the per-heating operation device 20 includes - a focusing portion 21 and a thermal signal extracting portion 22; the focusing portion h is for focusing and illuminating the thermal signal 911 to the thermal signal operating portion 22; the thermal signal capturing portion 22 has a plurality of channel points 22G , the plurality of channel points 22〇 surrounded by the thermal signal channel 221 and the plurality of boundary points 91〇 The area to be tested 91A corresponds to the heat to be tested 911A, and can be irradiated to the corresponding single-point temperature sensing head 1; the plurality of channel points 22 surround the heat The noise blocking surface 222 corresponds to the noise region 91B surrounded by the plurality of boundary points 91, and is used to block the thermal noise signal 9UB; a discrimination component 34 is connected to the plurality of single-point temperature sensing The head 10 has a set of thermal signal standard values 341, and the plurality of single-point temperature sensing heads 10 sensed that the thermal signal to be tested 911A is transmitted to the discriminating element 34 for use with the set of thermal signal standard values. 341 is compared, if it is consistent, it is determined that the object to be tested 91 is qualified; if not, it is determined that the object to be tested 91 is unqualified. In practice, the object to be tested 90 can be a liquid crystal display (LCD), a circuit board, or other objects that can be subjected to quality inspection at a temperature. The plurality of regions to be tested 91A on the object to be tested 90 are arranged in a matrix and overlap with the adjacent noise regions 91B. 6 M395825 The plurality of single-point temperature sensing heads 1 〇 are arranged in a matrix with the heat-receiving device 2 配合, and vary according to the size of the object to be tested (multiple numbers) The single-point temperature sensing head 10 and the thermal signal capturing device 2 are synchronized to perform displacement adjustment of the matrix state (see FIGS. 5 and 6). Each of the single-point temperature sensing heads 10 can be a thermal detector (THERMOPILE). The focusing portion 21 is provided with at least one lens (refer to the third and fourth figures. The moving lens 911A is focused and illuminated to the thermal signal capturing portion 22. The present invention further includes a processing unit 30 for: multiplexer 31 for sequentially transmitting the thermal signal to be tested 911A sensed by the plurality of single-point temperature sensing heads 10. An amplifier 32' is used to amplify the thermal signal 9iia as a signal. An analog/digital converter 33 for converting the thermal signal to be tested 911A from an analog signal to a digital signal. The discriminating element 34' is compared with the set of thermal signal standard values 341 by the thermal signal to be tested 911A to determine whether the object to be tested 91 is qualified. A display 35 is coupled to the processing unit 3 for displaying the result of the discriminating element 34 against the thermal signal 911A. The use of the creation method is to activate a plurality of single-point temperature sensing heads 1 (refer to 7 M395825 and the first and seventh figures) to sense the same through the corresponding thermal signal extraction device 2〇' The thermal signal 911 from the corresponding thermal sensing area 91 on the object to be tested 9 is taken as an example of one of the single-point temperature sensing heads 1 and the thermal signal capturing device 20 as follows: The thermal signal 911 of the temperature sensing head 10 through the corresponding thermal signal operation device 2 includes a corresponding thermal sensing area 91 (including the corresponding noise area of the area to be tested 91A and the surrounding area) The thermal signal 911A and the thermal noise signal 911B emitted from the circular sensing region formed by the region 91B, when the thermal signal 911 passes through the focusing portion 21, and is focused and irradiated to the thermal signal capturing portion 22, only the waiting The thermal signal 911A can pass through the thermal signal channel 221 and be irradiated to the single-point temperature sensing head 10, so that the thermal noise signal 911B is blocked by the thermal noise blocking surface 222. When a plurality of single-point temperature sensing heads 10 transmit the sensed thermal signal 911A to the processing unit 30 ′, the multiplexer 31 sequentially transmits the amplifier to the amplifier 32 and the analog/digital converter 33. The processing operation such as amplification and analog-to-digital conversion is performed by the discriminating element 34 based on the set of thermal signal standard values 341. Here, there are at least two types of discriminating methods: [a] When the object to be tested The plurality of test areas 91A of 90 should be the same temperature. If the object to be tested 90 is an LCD, the temperature of the entire panel should be the same whether it is activated or opened or closed. Assuming that there are nine areas to be tested 91A, each hot test signal 911A (the standard value of the heat signal at this time) 341 is equal to the thermal signal to be tested 911A) in the same temperature range 'as long as one of the thermal signal to be tested 911A and its 8 M395825 eight do not meet, it is judged as unqualified. [b] When the plurality of test areas 91A of the test object 90 are at different temperatures. If the object to be tested 90 is a circuit board, each of the regions to be tested 91A may have different operating temperatures with different circuit components. At this time, the thermal signal standard value 341 is matched with each of the to-be-tested regions 91A. It is necessary to meet the requirements of nine hot test signals 911A. In addition, there are at least two adjustment methods for this creation: [1] Adjusting the focus portion 21. The focusing portion 21 of the present invention is provided with two coaxially movable mirrors, and the size of the Si is independent (for example, the length_ is the same as the third figure, and the width of the object to be tested is 9较, which is a wide distance L1. The fourth figure is 9 待 of the object to be tested having a narrow distance L2, and the two lenses are at least movable relative to each other between the first interval XI and the second interval X2. As long as the two lenses are controlled to move relative to each other, the thermal signal 911 can be accurately focused and illuminated on the thermal signal capturing portion 22. [2] Adjust the complex solution type temperature surface (1) and the number of thermal signal devices 20 for matrix adjustment. The matrix arrangement of a plurality of single-point temperature sensing heads 1G and the basic ageing device 2() Xianlong of this creation (for example, the width is the same as the example), the margin is a small miscellaneous L3. The object is 9〇' and the sixth figure is 9待 of the object to be tested with a large distance 〇. It can be used as a tool - the adjustment of the third spacing X3 and a fourth spacing ,), facing the different dimensions of the test The object 90 'Yang Gang Wei Jie Fu Wen silk surface (7) and the plurality of thermal communication device 2G synchronous (four) _ whole (wire can also serve 9 M395825 X-axis direction or only the Y-axis direction adjustment). The advantages and effects of this creation can be summarized as follows: The temperature of the entire area can be detected. In this creation, the average number of single-point temperature-sensing sensors corresponds to the total area of the object to be tested. Regardless of the size of the object to be tested, the area of the entire object to be tested can be measured by a plurality of single-point temperature sensing heads. There are nine areas to be tested. As long as one area to be tested does not meet the standard, it is not suitable. There will be no sampling style (for example, only three of the normal areas to be tested are detected, while the other six have two areas of fatigue. ) Detecting problems that are prone to errors. [2] Undisturbed by outside noise. Each of the single-point temperature sensing heads of the present invention has a focusing portion that focuses and transmits a thermal signal from a corresponding sensing area to the thermal signal capturing portion, and the thermal signal capturing portion blocks the thermal noise signal. Only the hot signal to be tested on the area to be tested is irradiated to the single-point temperature sensing head, so it is not interfered by external heat and noise signals. [3] Non-contact sensing speed is fast. This creation system uses a thermal detector to sense (non-contact) the heat signal emitted by the area to be tested. Because there is no connection to the area to be tested, no contact sensing is limited by the heat transfer rate of the material (heat transfer speed of different materials) Different) 'The sensing speed is quite fast. [4] The device is simple. This creation is only a simple setting of the _detector 'thermal signal acquisition unit (as long as the heat-resistant plate is burrowed in the middle), the lens group and the judgment unit, all of which are known devices. The above is only a detailed description of the simple and cost-effectiveness of the present invention by the preferred embodiment, and the spirit and scope of the extract.
