Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to an inspection equipment. Background Art

[0002] Inspection equipment uses X-ray beams to irradiate workpieces or human bodies, etc., and judges the quality of the workpiece based on the scanned image, or diagnoses diseases. Inspection equipment is widely used in quality inspection, medical, security inspection, etc.

[0003] In the related art, there is an inspection device that combines CT equipment and DR equipment. CT imaging and DR imaging are performed on the inspected object through the CT equipment and DR equipment, and a more comprehensive judgment result is made on the inspected object through the CT image and DR image. The radiation source and detector of the CT equipment are in a rotating state during operation. Therefore, when the inspection equipment is in operation, the CT equipment usually generates a lot of heat, and the CT equipment needs to be cooled to avoid high temperature damage to the device.

In the related art, there is a heat dissipation component installed near the CT equipment to dissipate the heat of the CT equipment. The DR equipment usually adopts natural heat dissipation, and the heat dissipation effect is not good.

[0046] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0047] The terms used herein are only for describing specific embodiments and are not intended to limit the present invention. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Combine the following Figures 1 to 6 An inspection apparatus according to an embodiment of the present invention is described.

[0050] like Figure 1 and Figure 2As shown, the inspection device provided by the embodiment of the present invention includes a scanning channel, a first scanning device 10, a second scanning device 20, a first cover 11, a second cover 21 and a heat dissipation device 30. The first scanning device 10 is configured to radiate rays toward the object to be inspected in the scanning channel to form a first scanned image. The second scanning device 20 is arranged on one side of the first scanning device 10, and is configured to radiate rays toward the object to be inspected to form a second scanned image. Among them, the first scanning device 10 and the second scanning device 20 have different imaging modes. A first accommodating space is formed inside the first cover 11, and the first accommodating space accommodates the first scanning device 10. A second accommodating space is formed inside the second cover 21, and the second accommodating space accommodates the second scanning device 20. The heat dissipation device 30 is arranged in one of the first cover 11 and the second cover 21, and is used to adjust the temperature inside the first cover 11 and the second cover 21.

[0051] Exemplarily, the inspection device includes a first cover body 11 that covers the first scanning device 10 and a second cover body 21 that covers the second scanning device 20. A first accommodating space is formed in the first cover body 11, and the first scanning device 10 is installed in the first accommodating space. A second accommodating space is formed in the second cover body 21, and the second scanning device 20 is installed in the second accommodating space. The first cover body 11 is used to protect the first scanning device 10 installed inside, and the second cover body 21 is used to protect the second scanning device 20 installed inside, while preventing radiation from leaking into the external environment.

[0052] like Figure 4 and Figure 6 As shown, the scanning channel includes a first scanning channel 100 located inside the first scanning device 10 and a second scanning channel 200 located inside the second scanning device 20. The first scanning channel 100 and the second scanning channel 200 are connected to each other, so that after the object to be inspected is inspected at the first scanning device 10, it can directly enter the second scanning channel 200 from the first scanning channel 100 for inspection. The first scanning device 10 and the second scanning device 20 have different imaging modes.

[0053] In some embodiments, the first scanning device 10 includes a first ray source, a first detector and a rotating frame, the first ray source and the first detector are mounted on the rotating frame, and the rotating frame is configured to rotate around the central axis of the first scanning channel 100. The first scanning device 10 is used to radiate rays to the object to be inspected at the first scanning channel 100 to form a CT image. The second scanning device 20 includes a second ray source, a second detector and a mounting frame, the second ray source and the second detector are mounted on the mounting frame. The second scanning device 20 is used to radiate rays to the object to be inspected at the second scanning channel 200 to form a DR image.

[0054] It is understandable that when the first scanning device 10 is in operation, since the first ray source, the first detector and the rotating frame are in a rotating state, a lot of heat is generated, and the first scanning device 10 needs to be efficiently cooled to meet the heat dissipation requirement of the first scanning device 10. When the second scanning device 20 is in operation, less heat is generated, and the heat dissipation requirement of the second scanning device 20 can be met by performing low-efficiency cooling on the second scanning device 20.

[0055] The heat dissipation device 30 includes a refrigeration unit, an air circulation unit, an electrical control unit, a box unit, and other components. The heat dissipation device 30 is a general air conditioning device, and the working principle of the heat dissipation device 30 is not described in detail. The heat dissipation device 30 is installed in the first cover 11 and can dissipate heat for the first scanning device 10.

[0056] Optionally, by providing air ducts in the first cover body 11 and the second cover body 21, at least part of the cold air generated by the heat dissipation device 30 can flow into the second cover body 21 to dissipate heat for the second scanning device 20. Most of the cold air generated by the heat dissipation device 30 flows in the first cover body 11, which can efficiently dissipate heat for the first scanning device 10, and at least part of the cold air can flow into the second cover body 21, meeting the heat dissipation requirements of the second scanning device 20.

[0057] In an embodiment of the present invention, the heat dissipation device 30 is installed on one of the first cover body 11 and the second cover body 21, and at least part of the cold air generated by the heat dissipation device 30 can flow into the other one, thereby realizing on-demand heat dissipation of the first scanning device 10 and the second scanning device 20, which can meet the heat dissipation requirements of the two scanning devices while having low energy consumption.

[0058] like Figures 3 to 6 As shown, in an optional embodiment, a first vent 310 is provided at a position where the first cover 11 and the second cover 21 are connected, and the first vent 310 communicates with the first cover 11 and the second cover 21. The heat dissipation device 30 includes an air conditioning device 33 and a first air guide component 31, the air conditioning device 33 is arranged in the first cover 11, and the first air guide component 31 is arranged at the first vent 310, and is used to guide the cold air in the first cover 11 into the second cover 21.

[0059] Exemplarily, the air conditioning device 33 is installed in the first cover body 11, and the operating parameters of the air conditioning device 33 can be adjusted by a remote control or buttons, so that the air conditioning device 33 operates at a set temperature and a set wind speed, so that the temperature in the first cover body 11 is maintained at a first target temperature, which is the ambient temperature of the first scanning device 10.

[0060] The first air guide component 31 includes a device capable of driving airflow, such as a blower and a fan. For example, the first air guide component 31 includes a fan, which is defined as a first fan.

[0061] In some embodiments, the first housing 11 and the second housing 21 are connected through a connecting pipe, and the connecting pipe is located outside the first housing 11 and the second housing 21. The first fan is installed in the connecting pipe, and the first fan rotates to send the cold air in the first housing 11 into the second housing 21 through the connecting pipe. After the cold air entering the second housing 21 exchanges heat with the air in the second housing 21, it is discharged to the external environment from the end of the second housing 21 away from the first housing 11.

[0062] In some embodiments, a vent is provided at a position where the first cover 11 and the second cover 21 are connected, and the vent is defined as a first vent 310. The first vent 310 connects the first cover 11 and the second cover 21. The first fan is installed at the first vent 310, and the first fan rotates to send the cold air in the first cover 11 into the second cover 21 through the first vent 310. After the cold air entering the second cover 21 undergoes heat exchange with the original air in the second cover 21, it is discharged to the external environment from the end of the second cover 21 away from the first cover 11.

[0063] It is understandable that a plurality of first fans may be arranged at intervals along the circumferential direction of the second cover body 21 to increase the flow rate of cold air flowing into the second cover body 21 per unit time and enhance the heat dissipation effect on the second scanning device 20 .

[0064] In an embodiment of the present invention, a first vent 310 is provided at a position where the first cover body 11 and the second cover body 21 are connected, and a first air guide component 31 is installed at the first vent 310, so as to rationally utilize the internal space of the inspection equipment and facilitate the smooth flow of cold air in the first cover body 11 into the second cover body 21.

[0065] like Figures 3 to 6 As shown, in an optional embodiment, a second vent 320 is provided at a position where the first cover 11 and the second cover 21 are connected, and the second vent 320 communicates with the first cover 11 and the second cover 21. The heat dissipation device 30 also includes a second air guide component 32, which is provided at the second vent 320 and is used to guide the hot air in the second cover 21 into the first cover 11.

[0066] Exemplarily, a second vent 320 is provided at a position where the first cover 11 and the second cover 21 are connected, and the second vent 320 communicates with the first cover 11 and the second cover 21. The second air guide component 32 includes a device such as a blower and a fan that can drive airflow. For example, the second air guide component 32 includes a fan, which is defined as a second fan.

[0067] The first fan is installed at the first vent 310, and the second fan is installed at the second vent 320. It is understandable that the blades of the first fan and the blades of the second fan rotate in different directions. For example, the first fan rotates in a clockwise direction, and the second fan rotates in a counterclockwise direction. The first fan rotates to send the cold air in the first cover 11 into the second cover 21, and the cold air exchanges heat with the air in the second cover 21. The second fan rotates to send the hot air in the second cover 21 into the first cover 11. The circulation of cold air and hot air between the first cover 11 and the second cover 21 is achieved by the first fan and the second fan.

[0068] If the hot air in the second cover 21 is discharged from the end of the second cover 21 away from the first cover 11, a more complicated structure is required to meet the requirements of hot air discharge and sealing. In the embodiment of the present invention, a second vent 320 is set at the position where the first cover 11 and the second cover 21 are connected, and the second fan is installed at the second vent 320, so as to reasonably utilize the internal space of the inspection equipment and facilitate the hot air in the second cover 21 to flow smoothly into the first cover 11.

[0069] In an embodiment of the present invention, the cold air entering the second cover body 21 through the first vent 310 exchanges heat with the air in the second cover body 21, and the hot air in the second cover body 21 enters the first cover body 11 through the second vent 320, and is converted into cold air through the refrigeration function of the air-conditioning equipment 33. The cold air and the hot air circulate between the first cover body 11 and the second cover body 21, thereby achieving heat dissipation for the two scanning devices and making full use of the internal space of the first cover body 11 and the second cover body 21, which is conducive to the compactness of the overall structure.

[0070] like Figures 3 to 6 As shown, in an optional embodiment, the first cover body 11 includes a first cover plate 111 facing the second cover body 21, the second cover body 21 includes a second cover plate 211 facing the first cover body 11, and the first cover plate 111 and the second cover plate 211 are arranged in close contact. At least one first vent 310 is located at the bottom of the docking position of the first cover plate 111 and the second cover plate 211, and at least one second vent 320 is located at the top of the docking position of the first cover plate 111 and the second cover plate 211. The first air guide component 31 includes a first fan, and the first fan is arranged at the first vent 310. The second air guide component 32 includes a second fan, and the second fan is arranged at the second vent 320.

[0071] Exemplarily, the first air guide component 31 includes a first fan, and the second air guide component 32 includes a second fan. The fan drives the air to flow between the first cover body 11 and the second cover body 21, and the fan has the advantages of low energy consumption and low noise during operation.

[0072] The first cover body 11 is usually formed by splicing a plurality of cover plates. To facilitate assembly of the first cover body 11 and disassembly of the first cover body 11 for regular maintenance of the first scanning device 10 inside the first cover body 11, the cover plates can be connected by fasteners, which include screws and nuts.

[0073] The second cover body 21 is usually formed by splicing a plurality of cover plates. To facilitate assembly of the second cover body 21 and disassembly of the second cover body 21 for regular maintenance of the second scanning device 20 inside the second cover body 21, the cover plates can be connected by fasteners, which include screws and nuts.

[0074] The first cover body 11 includes a first cover plate 111 facing the second cover body 21, and the second cover body 21 includes a second cover plate 211 facing the first cover body 11, and the first cover plate 111 and the second cover plate 211 are arranged in close contact. The first vent 310 and the second vent 320 are located at positions where the first cover plate 111 and the second cover plate 211 are connected. A first ventilation hole is provided on the first cover plate 111, and a second ventilation hole is provided on the second cover plate 211. The first ventilation hole and the second ventilation hole are coaxially arranged and connected to each other, and the first ventilation hole and the second ventilation hole form a ventilation hole connecting the first cover body 11 and the second cover body 21. The ventilation hole located at a lower position is defined as the first ventilation hole 310, and the ventilation hole located at a higher position is defined as the second ventilation hole 320.

[0075] The first vents 310 are located near the bottom of the first cover plate 111 and the second cover plate 211, and the second vents 320 are located near the top of the first cover plate 111 and the second cover plate 211. The number of the first vents 310 is set according to actual needs, and the number of the second vents 320 is set according to actual needs.

[0076] The first fan is installed at the first vent 310. The first fan rotates to introduce the cold air in the first cover 11 from the first vent 310 at a lower position into the second cover 21. The second fan is installed at the second vent 320. The second fan rotates to introduce the hot air in the second cover 21 from the second vent 320 at a higher position into the first cover 11. Air with a higher temperature will rise due to its lower density, and air with a lower temperature will sink due to its higher density.

[0077] The first vent 310 and the second vent 320 are spaced apart in the height direction, and the position of the second vent 320 is higher than that of the first vent 310, so that the cold air entering the second cover body 21 can fully exchange heat with the air in the second cover body 21 during the flow process, thereby enhancing the heat exchange effect and further improving the heat dissipation effect of the second scanning device 20.

[0078] In an embodiment of the present invention, the first vent 310 is located at the bottom of the docking position of the first cover plate 111 and the second cover plate 211, the second vent 320 is located at the top of the docking position of the first cover plate 111 and the second cover plate 211, the first fan is installed at the first vent 310, and the second fan is installed at the second vent 320, so that the cold air flows along a longer path in the second cover body 21, further improving the heat dissipation effect of the second scanning device 20 and other components in the second cover body 21.

[0079] like Figures 3 to 6 As shown, in an optional embodiment, at least one first fan is disposed on a first side of the second cover plate 211 , and at least one first fan is disposed on a second side of the second cover plate 211 .

[0080] The first cover body 11 has a first side and a second side opposite to each other along the width direction of the first cover body 11, and the second cover body 21 has a first side and a second side opposite to each other along the width direction of the second cover body 21. At least one first vent 310 is provided on the first side of the first cover plate 111 and the second cover plate 211, and at least one first vent 310 is provided on the second side of the first cover plate 111 and the second cover plate 211.

[0081] In some embodiments, two first vents 310 are provided on the first side of the first cover plate 111 and the second cover plate 211, and the two first vents 310 are spaced apart in the vertical direction. Two first vents 310 are provided on the second side of the first cover plate 111 and the second cover plate 211, and the two first vents 310 are spaced apart in the vertical direction. There are four first fans, and the four first fans are respectively installed at the four first vents 310. The four first fans rotate synchronously, which can effectively increase the flow rate of cold air entering the second cover body 21 per unit time.

[0082] There is no specific limit on the number of first fans. Some of the multiple first fans can be controlled to rotate, or all of the multiple first fans can be controlled to rotate. For example, in the hot summer, multiple first fans rotate at the same time to increase the flow of cold air entering the second cover body 21 per unit time, thereby ensuring the heat dissipation effect. In the cold winter, some of the first fans rotate to ensure the heat dissipation effect while reducing energy consumption. In addition, when some of the first fans fail, cold air still flows into the second cover body 21.

[0083] The first scanning channel 100 and the second scanning channel 200 are both approximately square in shape. The second ray source, the second detector and other components are distributed in the circumferential direction of the second scanning channel 200. An air guide plate and an air guide channel may be provided in the second cover body 21 to guide the flow of air.

[0084] For example, an air guide channel is installed at the first fan on the first side, and the air guide channel has a tendency to bend toward the second side. The cold air enters the air guide channel driven by the first fan, and the air guide channel guides the cold air to flow toward the second side, thereby increasing the flow path of the cold air. During the flow, the cold air exchanges heat with the air in the second cover body 21, thereby effectively improving the heat dissipation effect of the second scanning device 20 and components in the second cover body 21.

[0085] In an embodiment of the present invention, a plurality of first fans are arranged on the first side and the second side of the first cover body 11 and the second cover body 21, which not only increases the air flow rate, but also facilitates sufficient heat exchange between the cold air and the air in the second cover body 21. The number of first fans turned on can be controlled as needed, which not only meets the heat dissipation requirements but also reduces energy consumption.

[0086] like Figures 3 to 6 As shown, in an optional embodiment, at least one second fan is disposed on a first side of the second cover plate 211 , and at least one second fan is disposed on a second side of the second cover plate 211 .

[0087] At least one second vent 320 is disposed on a first side of the first cover plate 111 and the second cover plate 211 , and at least one second vent 320 is disposed on a second side of the first cover plate 111 and the second cover plate 211 .

[0088] In some embodiments, two second vents 320 are provided on the first side of the first cover plate 111 and the second cover plate 211, and the two second vents 320 are spaced apart in the vertical direction. Two second vents 320 are provided on the second side of the first cover plate 111 and the second cover plate 211, and the two second vents 320 are spaced apart in the vertical direction. There are four second fans, and the four second fans are respectively installed at the four second vents 320. The four second fans rotate synchronously, which can effectively increase the air flow rate of introducing the hot air in the second cover body 21 into the first cover body 11 per unit time.

[0089] There is no specific limit on the number of second fans. Some of the multiple second fans can be controlled to rotate, or all of the multiple second fans can be controlled to rotate. For example, in the hot summer, multiple second fans rotate at the same time to increase the air flow rate of the hot air in the second cover body 21 per unit time, thereby ensuring the heat dissipation effect. In the cold winter, some of the second fans rotate to ensure the heat dissipation effect while reducing energy consumption. In addition, in the event of failure of some of the second fans, the hot air in the second cover body 21 can still be introduced into the first cover body 11.

[0090] In an embodiment of the present invention, a first fan is installed on the first side and the second side of the first cover plate 111 and the second cover plate 211, and a second fan is installed on the first side and the second side of the first cover plate 111 and the second cover plate 211, which is beneficial to increase the air flow and enhance the heat dissipation effect of the second scanning device 20. At the same time, in the event of failure of some fans, the second scanning device 20 can still be cooled, thereby ensuring the reliable operation of the inspection equipment.

[0091] In an optional embodiment, the inspection device further includes a first temperature sensor and / or a second temperature sensor. The first temperature sensor is disposed in the first housing 11 and is used to detect a first real-time temperature in the first housing 11. The second temperature sensor is disposed in the second housing 21 and is used to detect a second real-time temperature in the second housing 21.

[0092] Exemplarily, a first temperature sensor is installed in the first housing 11 to detect the real-time temperature in the first housing 11, and this real-time temperature is defined as the first real-time temperature. A second temperature sensor is installed in the second housing 21 to detect the real-time temperature in the second housing 21, and this real-time temperature is defined as the second real-time temperature.

[0093] The first real-time temperature is the ambient temperature of the first scanning device 10. By detecting the first real-time temperature in real time, it is ensured that the first scanning device 10 works within the first target temperature range to avoid the first real-time temperature being too high due to unexpected conditions, thereby damaging the parts of the first scanning device 10. If the first real-time temperature is higher than the preset temperature, the ambient temperature of the first scanning device 10 is adjusted by adjusting the set temperature, set wind speed and other parameters of the air conditioning device 33.

[0094] The second real-time temperature is the ambient temperature of the second scanning device 20. By detecting the second real-time temperature in real time, it is ensured that the second scanning device 20 works within the second target temperature range to avoid the second real-time temperature being too high due to unexpected conditions, thereby damaging the parts of the second scanning device 20. If the second real-time temperature is higher than the preset temperature, the ambient temperature of the second scanning device 20 is adjusted by adjusting the set temperature, set wind speed and other parameters of the air conditioning device 33, and adjusting the number of the first fan and the second fan turned on.

[0095] In an embodiment of the present invention, by real-time detection of the first real-time temperature in the first cover body 11 and the second real-time temperature in the second cover body 21, the ambient temperature of the operation of the first scanning device 10 and the second scanning device 20 is fed back. When the first real-time temperature and the second real-time temperature are higher than the preset temperature, the operating parameters of the air-conditioning equipment 33 are adjusted in time to ensure that the first scanning device 10 and the second scanning device 20 can operate within their respective target temperature ranges, which is beneficial to improving the reliability of the operation of the inspection equipment.

[0096] In an optional embodiment, the inspection device further includes a first control unit, which is communicatively connected to the second temperature sensor and is configured to control operating parameters of the first fan according to the second real-time temperature.

[0097] Exemplarily, a plurality of first fans are connected in communication with a first control unit, and the first control unit is capable of controlling the opening, closing, and rotation speed of the first fans, and the rotation speed of the first fans is defined as a first rotation speed. A second temperature sensor is connected in communication with the first control unit, and the first control unit controls the operating parameters of the first fans according to the detected second real-time temperature and the comparison result between the second real-time temperature and the second target temperature. The operating parameters include the number of first fans turned on and the first rotation speed of the first fans.

[0098] For example, the second real-time temperature is greater than the second target temperature, and the difference between the second real-time temperature and the second target temperature is greater than the second preset difference. The temperature inside the second cover 21 can be adjusted by increasing the number of first fans turned on and / or increasing the first speed of the first fan.

[0099] For example, if the second real-time temperature is lower than the second target temperature, and the difference between the second real-time temperature and the second target temperature is higher than the second preset difference, the temperature inside the second cover 21 can be adjusted by reducing the number of first fans turned on and / or reducing the first speed of the first fan.

[0100] In an embodiment of the present invention, according to the second real-time temperature detected by the second temperature sensor, the first control unit controls the number of first fans turned on and / or the first speed of the first fan. When the temperature inside the second cover body 21 is too high, the temperature can be reduced in time to ensure the heat dissipation effect. At the same time, when the temperature inside the second cover body 21 is too low, the operating parameters of the first fan are adjusted to help reduce energy consumption.

[0101] In an optional embodiment, the inspection device further includes a second control unit, which is communicatively connected to the second temperature sensor and is configured to control operating parameters of the second fan according to the second real-time temperature.

[0102] Exemplarily, a plurality of second fans are connected in communication with the second control unit, and the second control unit can control the opening, closing and rotation speed of the second fans, and the rotation speed of the second fans is defined as the second rotation speed. The second temperature sensor is connected in communication with the second control unit, and the second control unit controls the operating parameters of the second fans according to the detected second real-time temperature and the comparison result between the second real-time temperature and the second target temperature. The operating parameters include the number of second fans turned on and the second rotation speed of the second fans.

[0103] For example, the second real-time temperature is greater than the second target temperature, and the difference between the second real-time temperature and the second target temperature is greater than the second preset difference. The temperature inside the second cover 21 can be adjusted by increasing the number of second fans turned on and / or increasing the second speed of the second fan.

[0104] For example, if the second real-time temperature is lower than the second target temperature, and the difference between the second real-time temperature and the second target temperature is higher than the second preset difference, the temperature inside the second cover 21 can be adjusted by reducing the number of second fans turned on and / or reducing the second speed of the second fan.

[0105] Optionally, if the second real-time temperature is greater than the second target temperature, and the difference between the second real-time temperature and the second target temperature is greater than the second preset difference, the temperature inside the second cover body 21 can be adjusted by increasing the number of first fans turned on and / or increasing the first speed of the first fan, and by increasing the number of second fans turned on and / or increasing the second speed of the second fan at the same time.

[0106] Optionally, if the second real-time temperature is lower than the second target temperature, and the difference between the second real-time temperature and the second target temperature is greater than the second preset difference, the temperature inside the second cover body 21 can be adjusted by reducing the number of first fans turned on and / or reducing the first speed of the first fan, and by simultaneously reducing the number of second fans turned on and / or reducing the second speed of the second fan.

[0107] In an embodiment of the present invention, according to the second real-time temperature detected by the second temperature sensor, the first control unit controls the number of first fans turned on and / or the first speed of the first fan, and the second control unit controls the number of second fans turned on and / or the second speed of the second fan. When the temperature inside the second cover body 21 is too high, the temperature can be quickly lowered to ensure the heat dissipation effect. At the same time, when the temperature inside the second cover body 21 is too low, the operating parameters of the first fan and the second fan are adjusted, which is conducive to further reducing energy consumption.

[0108] In some embodiments, the first control unit and the second control unit are both connected to the first temperature sensor for communication, and the first control unit and the second control unit are both connected to the second temperature sensor for communication. The first temperature sensor detects the first real-time temperature in the first housing 11, and the second temperature sensor detects the second real-time temperature in the second housing 21. The first control unit and the second control unit can dynamically adjust the operating parameters of the first fan and the second fan according to the comparison result of the first real-time temperature and the second real-time temperature, so that the first real-time temperature and the second real-time temperature are close, ensuring that the first scanning device 10 and the second scanning device 20 can both operate within a suitable target temperature range.

[0109] For example, the first real-time temperature is lower than the second real-time temperature, and the difference between the first real-time temperature and the second real-time temperature is greater than a set difference, for example, the set difference is 4 degrees. The first control unit increases the number of first fans turned on and / or increases the first speed of the first fan, and the second control unit increases the number of second fans turned on and / or increases the second speed of the second fan to strengthen the flow of cold air in the first cover 11 toward the second cover 21 and the flow of hot air in the second cover 21 toward the first cover 11, so that the difference between the first real-time temperature and the second real-time temperature is kept within the set difference.

[0110] For example, the first real-time temperature is greater than the second real-time temperature, and the difference between the first real-time temperature and the second real-time temperature is greater than the set difference. The first control unit reduces the number of first fans turned on and / or reduces the first speed of the first fan, and the second control unit reduces the number of second fans turned on and / or reduces the second speed of the second fan, thereby reducing the flow of cold air in the first cover 11 toward the second cover 21 and the flow of hot air in the second cover 21 toward the first cover 11, so that the difference between the first real-time temperature and the second real-time temperature remains within the set difference.

[0111] In an embodiment of the present invention, according to the first real-time temperature detected by the first temperature sensor and the second real-time temperature detected by the second temperature sensor, the first control unit and the second control unit dynamically adjust the operating parameters of the first fan and the second fan so that the first real-time temperature and the second real-time temperature are close, ensuring that the first scanning device 10 and the second scanning device 20 can both operate within an appropriate target temperature range.

[0112] In an optional embodiment, the air conditioning device 33 is communicatively connected to the first temperature sensor and / or the second temperature sensor for controlling the operating parameters of the air conditioning device 33 according to the first real-time temperature and / or the second real-time temperature.

[0113] Exemplarily, the operating parameters of the air conditioner 33 include a set temperature, a set wind speed, etc. The operating parameters of the air conditioner 33 may be adjusted according to the comparison result between the first real-time temperature and the first target temperature. The operating parameters of the air conditioner 33 may also be adjusted according to the comparison result between the second real-time temperature and the second target temperature.

[0114] For example, if the first real-time temperature is greater than the first target temperature, and the difference between the first real-time temperature and the first target temperature is greater than the first preset difference, the temperature inside the first cover body 11 can be adjusted by reducing the set temperature and / or increasing the set wind speed.

[0115] For example, if the first real-time temperature is lower than the first target temperature, and the difference between the first real-time temperature and the first target temperature is higher than the first preset difference, the temperature inside the first cover 11 can be adjusted by increasing the set temperature and / or reducing the set wind speed.

[0116] For example, if the second real-time temperature is greater than the second target temperature, and the difference between the second real-time temperature and the second target temperature is greater than the second preset difference, the temperature inside the second cover 21 can be adjusted by reducing the set temperature and / or increasing the set wind speed.

[0117] For example, if the second real-time temperature is lower than the second target temperature, and the difference between the second real-time temperature and the second target temperature is higher than the second preset difference, the temperature inside the second cover 21 can be adjusted by increasing the set temperature and / or reducing the set wind speed.

[0118] In the embodiment of the present invention, the set temperature and set wind speed of the air conditioner 33 are adjusted according to the first real-time temperature detected by the first temperature sensor. When the temperature in the first housing 11 is too high, the temperature can be reduced in time to ensure the heat dissipation effect. At the same time, when the temperature in the first housing 11 is too low, the operating parameters of the air conditioner 33 are adjusted, which is conducive to reducing energy consumption. According to the second real-time temperature detected by the second temperature sensor, the set temperature and set wind speed of the air conditioner 33 are adjusted. When the temperature in the second housing 21 is too high, more cold air can be quickly introduced into the second housing 21 to quickly reduce the temperature in the second housing 21. At the same time, when the temperature in the second housing 21 is too low, the operating parameters of the air conditioner 33 are adjusted, which is conducive to reducing energy consumption.

[0119] In an optional embodiment, the first cover plate 111 and the second cover plate 211 are sealed and connected via a sealing strip, and the sealing strip is configured to form a sealing area between the first cover plate 111 and the second cover plate 211 .

[0122] A sealing strip is provided along the circumferential direction of the edge of the second cover plate 211, and the sealing strip can be bonded to the edge of the second cover plate 211 by bonding to form a sealing area. After the first cover plate 111 and the second cover plate 211 are paired, the sealing strip is sandwiched between the first cover plate 111 and the second cover plate 211. The sealing strip can also be bonded to the first cover plate 111, and after the first cover plate 111 and the second cover plate 211 are paired, the sealing strip is sandwiched between the first cover plate 111 and the second cover plate 211.
