Description

Technical Field

[0001] The utility model relates to the field of infrared temperature data acquisition, and in particular to an infrared thermal image acquisition device and system. Background Art

[0002] If the surface temperature of an object exceeds absolute zero, it will radiate electromagnetic waves. As the temperature changes, the radiation intensity and wavelength distribution characteristics of the electromagnetic waves also change. Electromagnetic waves with wavelengths between 0.75μm and 1000μm are called "infrared rays".

[0003] In view of the fact that the magnitude of the thermal radiation energy of an object (i.e., the wavelength of infrared rays) is directly related to the surface temperature of the object, infrared thermal imaging technology has been developed, that is, a special electronic device is used to measure the thermal radiation energy distribution on the surface of an object, corresponding to the temperature distribution on the surface of the object, and then converted into an image visible to the human eye, and the surface temperature distribution of the object is displayed in different colors.

[0029] The following uses specific specific examples to illustrate the embodiments of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments.

It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. It should also be understood that the terms used in the embodiments of the present utility model are for the purpose of describing specific specific implementation schemes, rather than for limiting the protection scope of the present utility model. Without departing from the spirit and scope of the present application, the general principles defined here can be applied to other embodiments and applications. Therefore, the present application is not limited to the shown embodiments, but is the widest scope consistent with the claims.

[0030] Reference Figure 1 As shown, the present utility model provides an infrared thermal image acquisition device 100, which includes an infrared temperature detection module, a wireless communication module, a control module, and an external power supply interface. Among them, the infrared temperature detection module is used to collect infrared temperature data of a target object. The wireless communication module is used to provide a data transmission channel. The control module is electrically connected to the infrared temperature detection module and the wireless communication module, and is used to control the operation of the infrared thermal image acquisition device 100, including generating infrared thermal image data. The external power supply interface can be connected to an external power supply to supply power to the infrared thermal image acquisition device 100. In particular, in the infrared thermal image acquisition device 100 of the present utility model, the control module and the wireless communication module together constitute a wireless local area network (WLAN) and a network server (Server).

[0031] In some embodiments, the electrical connection between the control module and the infrared temperature detection module includes a control line from the control module to the infrared temperature detection module and a data line from the infrared temperature detection module to the control module. The electrical connection between the control module and the wireless communication module includes a control and data line from the control module to the wireless communication module and a status and data line from the wireless communication module to the control module.

[0032] Specifically, the infrared temperature detection module converts the infrared radiation energy collected on the surface of the target object into an electrical signal, then processes these electrical signals such as amplification and filtering, and then calculates the temperature data on the surface of the target object according to the corresponding relationship between the radiation energy and temperature on the object surface. The parameters of the infrared temperature detection module include infrared resolution, field of view angle, lens focal length, focusing method, temperature measurement range, temperature measurement accuracy, detection distance, etc. In some embodiments, for different application scenarios, infrared temperature detection modules with different parameter combinations can be selected to achieve high cost performance by making the best use of everything.

[0033] The wireless communication module plays the role of a data transmission channel in the present utility model, and can be a WiFi module, or a hardware module such as a Bluetooth module that can implement wireless communication, for data transmission between the infrared thermal image acquisition device 100 and external devices. In some embodiments of the present utility model, a WiFi module is preferably used.

[0034] The control module is responsible for the overall operation of the infrared thermal image acquisition device 100, and is electrically connected to the infrared temperature detection module and the wireless communication module. The control module is built-in with embedded control software, which controls the infrared temperature detection module and the wireless communication module respectively to realize the functions of the infrared thermal image acquisition device 100 of the present utility model. Specifically, in terms of acquiring infrared thermal images, the control software reads the detected real-time infrared temperature data from the infrared temperature detection module when needed, and then converts it into data suitable for imaging. There can be various data forms. In some embodiments, the control software processes the infrared temperature data into Raw Data (unconverted data) with a specific data structure for applications with special requirements. In other embodiments, the control software processes the infrared temperature data into image files in a standard format that can be directly displayed, such as JPG files, PNG files, etc.

[0035] The infrared thermal image acquisition device 100 of the present utility model does not have its own image display device, and the infrared thermal image is displayed by an external device, which can reduce the volume of the device, reduce components, and thus reduce costs. The external device can be a commonly used and easily available device for people, and it will not affect the use of the infrared thermal image acquisition device 100. For example, a mobile phone can be used as an external device that cooperates with the infrared thermal image acquisition device 100. The settings of the external device responsible for displaying the infrared thermal image involve the data transmission requirements for transmitting the infrared thermal image data from the infrared thermal image acquisition device 100 to the external device, and there can be various solutions. For example, in one solution, the two devices that need to transmit data to each other are connected to the same local area network to achieve data transmission; in another solution, the two devices are connected point-to-point to achieve data transmission. In particular, the present utility model adopts a "master-slave" network architecture. The control module of the infrared thermal image acquisition device 100 uses the wireless communication module to form an independent and complete wireless local area network (WLAN) and sets up a server. Thus, the infrared thermal image acquisition device 100 is the "master" device, and the external device is the "slave" device. The client on the "slave" device can establish a connection with the server on the "master" device to exchange data. In this way, the infrared thermal image acquisition device 100 of the present utility model can create a wireless local area network at any time and place without relying on an external network for the external device to access and complete the transmission of the infrared thermal image data. The setting of the wireless local area network enables the infrared thermal image acquisition device 100 of the present utility model to adapt to various external environments, and it can still operate smoothly even without any external network or in special environments such as caves and underground. At the same time, the external devices that cooperate with the infrared thermal image acquisition device 100 can also be diverse as long as they have the ability to access the wireless local area network. For example, mobile phones and mobile computers of various systems all have this ability.

[0036] In some embodiments, the control process of the infrared thermal image acquisition device 100 includes:

[0037] S11 The external power supply interface is connected to an external power source to provide power for the infrared thermal image acquisition device 100;

[0038] S12 The infrared temperature detection module, the control module, and the wireless communication module enter the working state;

[0039] S13 When the server receives a request to read an infrared thermal image sent from the outside via a wireless local area network, the control software reads the infrared temperature data from the infrared temperature detection module, generates infrared thermal image data, and transmits it via the wireless local area network.

[0040] The external power supply interface provides an access path for the external power source. It can select commonly used and easily available power sources, and there is no need to equip the infrared thermal image acquisition device 100 of the present utility model with a special power source. While reducing the total cost, it also increases portability. Commonly used hardware interfaces for powering electronic products include standard USB and USB-C (also known as USB Type-C). Among them, USB-C supports blind plugging in both directions and can provide voltages of 5V, 9V, 15V, or 20V externally, with a maximum power of 100W. It is being widely used and rapidly popularized. Therefore, as a preferred embodiment of the present utility model, the external power supply interface adopts USB-C.

[0041] The USB-C interface standard defines the specifications of the plug (also known as the male head) and the socket (also known as the female head). The plug and the socket are used in combination to complete the connection between different devices. In some embodiments, the external power supply interface adopts a plug type. In other embodiments, the external power supply interface adopts a socket type. In this way, the infrared thermal image acquisition device 100 of the present utility model provides adaptability flexibility. As long as there is a USB-C interface at the usage site, whether it is a plug type or a socket type, there is always one that can be applicable. Or, the user can select the infrared thermal image acquisition device 100 with the corresponding interface type according to the existing USB-C type devices in hand.

[0042] As can be seen from the above, the infrared thermal image acquisition device 100 of the present utility model has wide adaptability. As long as there is a USB-C connection cable, with a charger or a mobile phone, there is an external power source; mobile phones, computers, etc. with a USB-C interface can also provide an external power source. Any electronic device with a USB-C interface can be the provider of the external power source.

[0043] Reference Figure 2 As shown in the schematic diagram of the power supply circuit, the pins VBUS and GND of the USB-C interface provide power for the infrared thermal image acquisition device 100. Figure 2 (a) is the schematic diagram of the USB-C plug type in some embodiments,Figure 2 (b) is a schematic circuit diagram of a USB-C socket type in some embodiments. Refer to Figure 2 (c), the USB-C interface can provide 3.3V and 5V power supplies for the infrared thermal imaging acquisition device 100. Specifically, in some embodiments, refer to Figure 2 As shown in (a), the CC pin of the USB-C plug is grounded (GND), and the input of the VBUS pin is 5V; in some embodiments, refer to Figure 2 As shown in (b), both the CC1 pin and the CC2 pin of the USB-C socket are grounded (GND), and the input of the VBUS pin is 5V. In some embodiments, refer to Figure 2 As shown in (c), VBUS is connected to 5VIN through the fuse FU1 to provide 5V power supply for relevant components, and at the same time provides 3.3V power supply for relevant components through voltage conversion.

[0044] Furthermore, in some embodiments, the control module and the wireless communication module are integrated into one, which is a microprocessor control unit (MCU) with a built-in wireless communication module. In some embodiments, a microprocessor control unit with a built-in WiFi module is preferably used. For example, an MCU with a built-in general-purpose Wi-Fi module, configured with 4MB of embedded flash, and equipped with a RISC-V 32-bit single-core processor can meet the functional requirements of the infrared thermal imaging acquisition device 100 of the present utility model.

[0045] In some embodiments, the protocol used by the server of the infrared thermal imaging acquisition device 100 is the HTTP protocol, which is used for parameter setting of the infrared thermal imaging acquisition device and transmission of infrared thermal imaging data. The server provides an HTTP interface (API, Application Interface), and through preset (i.e., defined by the server) interface parameters, parameter setting of the infrared thermal imaging acquisition device 100 and transmission of infrared thermal imaging data are realized. In addition to acquiring infrared thermal imaging data, various parameters of the infrared thermal imaging acquisition device 100 can also be set for customization. The advantage of the HTTP interface lies in the easy availability of the client, and all browsers support HTTP. By entering the preset interface address and parameters in the browser on an external device connected to the wireless local area network of the infrared thermal imaging acquisition device 100, the real-time infrared thermal image detected by the infrared thermal imaging acquisition device 100 can be easily displayed without the need for an additional dedicated application.

The client is matched with the server of the infrared thermal image acquisition device 100, and the display device is used to display the infrared thermal image data received from the server.

[0048] The external power supply and the external device 200 can be integrated or independent of each other without any association.

[0049] In some embodiments, the control process of the infrared thermal image acquisition system includes:

[0050] S21 The external power supply is inserted into the external power supply interface of the infrared thermal image acquisition device 100;

[0051] S22 The infrared thermal image acquisition device 100 enters the working state;

[0056] In some embodiments, the client is a web browser. By entering the preset (i.e., defined by the server) IP address and parameters for acquiring the infrared thermal image in the address bar of the web browser, the infrared thermal image can be displayed on the display device.

[0057] In some embodiments, the client is a dedicated application (App). After obtaining the infrared thermal image data from the infrared thermal image acquisition device 100, various advanced applications can be realized, providing unlimited possibilities for future development.

[0058] In some embodiments, the client is a parameter setting and customization tool for the infrared thermal image acquisition device 100.
