[0061] Example 1

[0062] Combined with appendix Figure 1-8 This embodiment provides an automatic calibration system for radiation meters, including:

[0063] Transmission component 1;

[0064] At least one rotating component 2 is located on the transmission component 1, and the rotating component 2 is used to mount the radiation meter 3 to be tested;

[0065] Darkroom assembly 4, with door assembly 1 51 movably connected to one side of darkroom assembly 4 and door assembly 2 52 movably connected to the other side of darkroom assembly 4;

[0066] Rotating component 2 6 is connected within the darkroom assembly 4;

[0067] A standard radiation meter 7 is connected to the rotating assembly 2 6;

[0068] Sensor 8 is located at door assembly 51;

[0069] Sensor 29 is located at door assembly 2, 52;

[0070] Control component 104 is connected to transmission component 1, rotation component 1 2, rotation component 2 6, darkroom component 4, sensor 1 8, sensor 2 9, radiation meter under test 3, and standard radiation meter 7.

[0071] Among them, the transmission component 1 passes through the darkroom component 4, and door component 1 51 and door component 2 52 are arranged in sequence along the transmission direction of the transmission component 1.

[0072] Specifically, during the testing process, the radiation meter 3 to be tested is first installed on the rotating assembly 2. The control assembly 104 controls the transmission assembly 1 to transmit the rotating assembly 2 and the radiation meter 3. When the sensor 8 detects the rotating assembly 2 and the radiation meter 3, the sensor 8 transmits a signal to the control assembly 104. The control assembly 104 opens the door assembly 51, allowing the rotating assembly 2 and the radiation meter 3 to enter the dark chamber assembly 4, and then closes the door assembly 51, thus facilitating the formation of the dark chamber. When the rotating assembly 2 and the radiation meter 3 are aligned with the rotating assembly 6 and the standard radiation meter 7, the transmission assembly 1 is closed. It should be noted that the transmission assembly 1 can be closed automatically through the linkage between the relevant sensors, the transmission assembly 1, and the control assembly 104, or it can be closed manually by operating the control assembly 1. 04. After shutting down transmission component 1, automatically or manually connect the radiation meter under test 3 and control component 104, and automatically turn on the radiation source 42 and light-shielding unit 45 of the darkroom component 4. At the same time, according to the radiation meter calibration rules, control component 104 turns on rotation component 1 2 and rotation component 2 6 to drive the radiation meter under test 3 and the standard radiation meter 7 to rotate. At the same time, the radiation meter under test 3 and the standard radiation meter 7 transmit measurement signals to control component 104. When the entire calibration process is completed, control component 104 opens door component 2 52 and transmission component 1, so that rotation component 1 2 and radiation meter under test 3 leave the darkroom component 4. When sensor 2 9 detects rotation component 1 2 and radiation meter under test 3, sensor 2 9 transmits a signal to control component 104, and control component 104 closes door component 2 52, thereby completing the calibration of one radiation meter under test 3.

[0073] The transmission component 1 is used to move the rotating component 2 and the radiation meter 3 under test, thereby facilitating the sequential testing of multiple radiation meters 3 under test, resulting in high testing efficiency. Specifically, the transmission component 1 can be a belt transmission component, chain transmission component, etc. The rotating component 2 is used to install the radiation meter 3 under test and to cause it to rotate. To ensure testing, there must be at least one rotating component 2. When there are multiple rotating components 2, it facilitates the sequential testing of multiple radiation meters 3 under test, resulting in high testing efficiency. Specifically, the rotating component 2 can be a high-speed motor, low-speed motor, or constant-speed motor, etc. The darkroom component 4 is used to form a darkroom, facilitating indoor testing without needing to select a time with sunlight of a certain radiation intensity. It also avoids testing delays due to unexpected situations such as cloud cover or excessive wind speed, effectively reducing the testing time span and further increasing testing efficiency. Specifically, the darkroom component 4 can include a radiation source 42, a light-shielding unit 45, etc. The rotating component 6 is used for... The system includes a standard radiation meter 7 for installation and rotation, and a rotating assembly 6 that can be a high-speed motor, a low-speed motor, or a constant-speed motor. A sensor 8 is used to detect the positions of the rotating assembly 2 and the radiation meter 3 under test, and transmits the signal to the control assembly 104. Sensor 8 can be an infrared sensor, an ultrasonic sensor, etc. A sensor 9 is also used to detect the positions of the rotating assembly 2 and the radiation meter 3 under test, and transmit the signal to the control assembly 104. Sensor 9 can be an infrared sensor, an ultrasonic sensor, etc. The control assembly 104 receives signals from sensors 8, 9, the radiation meter 3 under test, and the standard radiation meter 7, and controls the opening and closing of the transmission assembly 1, rotating assembly 2, rotating assembly 6, and the anechoic chamber assembly 4. The control assembly 104 can include interconnected electrical control boxes, controllers, etc. Door assemblies 51 and 52 can be sliding door assemblies, rotating door assemblies, etc.

[0074] Furthermore, it also includes sensor 3 10 located within the anechoic chamber assembly 4, which is connected to the control assembly 104.

[0075] Specifically, sensor 3 10 is supported by anechoic chamber assembly 4 and is used to detect the position of rotating assembly 1 2 and radiation meter 3 under test. When rotating assembly 1 2 and radiation meter 3 under test are on the same straight line as rotating assembly 2 6 and standard radiation meter 7, sensor 3 10 transmits a signal to control assembly 104. Control assembly 104 shuts down transmission assembly 1, thereby realizing the automatic opening and closing of transmission assembly 1, which further improves the verification efficiency. Sensor 3 10 can be an infrared sensor, ultrasonic sensor, etc.

[0080] The lifting assembly 102 and the signal terminal 103 are both connected to the control assembly 104.

[0081] Specifically, when the control component 104 shuts down the transmission component 1 due to the detection of sensor 3 10, the control component 104 opens the lifting component 102. The lifting component 102 drives the signal terminal 2 103 to move, and makes the signal terminal 2 103 cooperate with the signal terminal 101, thereby completing the automatic connection between the radiation meter under test 3 and the control component 104, further improving the calibration effect. The lifting component 102 can be an electric lifting component, a pneumatic lifting component, or a hydraulic lifting component, etc.

[0086] The rotating component 2 6 is connected inside the housing 41, and the radiation source 42 and the light-shielding unit 45 are both connected to the control component 104.

[0087] Specifically, the housing 41 supports the radiation source 42, the light-shielding unit 45, etc. Since both door assembly 51 and door assembly 52 are movably connected to the housing 41, it is convenient to open and close the housing 41. The radiation source 42 is used to emit radiation light, and since the radiation source 42 is movably connected to the housing 41, it is beneficial to increase the uniformity of the radiation light. The radiation source 42 can be a xenon arc lamp, a tungsten filament lamp, or a carbon arc lamp, etc. The light-shielding unit 45 is used to shield the radiation light, which is convenient to form a dark room inside the housing 41. Since the light-shielding unit 45 is movably connected to the housing 41, and since the light-shielding unit 45 is located between the radiation source 42 and the radiation meter 3 under test and the standard radiation meter 7, it is convenient to allow the radiation meter 3 under test and the standard radiation meter 7 to continuously alternate between radiation-containing and non-radiation-containing environments, thereby adapting to the calibration rules of the radiation meter. The light-shielding unit 45 can be made of black material.

[0088] Furthermore, the anechoic chamber assembly 4 also includes a heat dissipation unit 43 connected to the top of the housing 41, and the heat dissipation unit 43 is connected to the control assembly 104.

[0089] Specifically, the heat dissipation unit 43 is supported by the housing 41 and is used to dissipate the heat inside the housing 41.

[0091] Specifically, the dust removal unit 44 is supported by the housing 41 and is used to remove dust from the air inside the housing 41. Since the dust removal unit 44 is connected to the bottom of the housing 41, and since the dust will move towards the bottom of the housing 41 under the action of gravity, it is convenient to further remove the dust from the air inside the housing 41. The dust removal unit 44 may include several filters with different filtration precisions, so that the dust can be evenly distributed on several filters and effectively prevent one filter from becoming clogged.

[0092] Furthermore, the heat dissipation unit 43 includes:

The fan module 432 can be an axial flow fan module, a mixed flow fan module, etc. In order to ensure heat dissipation, the number of fan modules 432 is at least one. At the same time, the specific number of fan modules 432 is not limited and can be determined by comprehensive consideration of factors such as processing and manufacturing costs.
