Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of astronomical domes, and in particular provides a control method and a control system for a hydraulic open dome. Background Art

[0002] Optoelectronic telescopes are precision observation and measurement instruments, comprising subsystems such as the optical system, focusing system, derotation system, imaging system, and turntable control system. Telescopes are typically used in non-extreme weather conditions, such as clear skies, calm winds, or light breezes. However, strong winds, rain, and dust storms are common, which can easily corrode and damage telescopes. Once installed, telescopes cannot be disassembled or moved, so each telescope is typically protected by a dome to prevent adverse weather conditions.

[0003] Traditional visible light telescopes are mainly used for nighttime observations. Although in recent years telescopes based on the infrared band that can be used for daytime observations have gradually become the key research direction of scientific research institutions at home and abroad, due to the high detection capability and positioning accuracy of visible light telescopes, they are still an irreplaceable type of observation equipment for scientific research institutions such as observatories and observation stations. For this type of telescope, it is usually equipped with a fixed base and a dome with a skylight that can be fully opened or closed, that is, an open dome. The diameter of the open dome is usually several times the diameter of the telescope. Large open domes require the use of hydraulic support rods to open or close the dome protective cover. For example, an observatory built a 10-meter diameter hydraulic open dome for a 2.5-meter aperture telescope.

[0004] The hydraulic oil in the hydraulic strut will become viscous or solidify when the temperature is too low. When the hydraulic open dome is opening or closing the dome protective cover, the temperature of the hydraulic oil in the hydraulic strut needs to be higher than its required minimum operating temperature. Therefore, it is necessary to configure electric heating for the hydraulic strut and control the electric heating to heat the hydraulic strut when necessary. Through heat conduction, the hydraulic oil in the hydraulic strut is heated to above the minimum operating temperature to ensure that the dome protective cover can be opened or closed smoothly.

[0005] Unmanned astronomical observations throughout the entire process have been a major research focus in recent years during the development, deployment, and operation of telescopes. Intelligent control of hydraulic open domes is a crucial component in automating the observation process for large electro-optical telescopes. This is especially true for electro-optical telescopes used for nighttime observations. If the design is not well-designed, the dome cover may not be opened in time before the start of an observation, resulting in data loss. Alternatively, the cover may not be closed in time at the end of an observation, leading to prolonged oversaturation of the visible light camera and even damage. Hydraulic open domes require electric heating for a period of time in low-temperature environments to ensure proper function of the hydraulic struts. If the electric heating components are operating continuously, significant power consumption is generated. According to statistics, a single telescope at one observatory with a hydraulic open dome can incur a monthly electricity bill increase of tens of thousands of yuan if the electric heating is constantly running in winter. Therefore, intelligent control systems for hydraulic open domes are essential for scientific experimentation, telescope protection, energy conservation, emissions reduction, and economic benefits.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] like Figure 1 As shown, an embodiment of the present invention provides a control method for a hydraulic open dome, wherein the hydraulic open dome uses a hydraulic support rod to open or close the dome protective cover. The specific contents of the control method for the hydraulic open dome are as follows: The hydraulic open dome closes or opens the dome protection cover according to the weather conditions, thereby protecting the telescope. Therefore, different weather conditions need to be divided. In the embodiment of the present invention, the range of meteorological data adopted is defined as the humidity, wind speed, cloud cover and rain and snow of the external environment, and each type of meteorological data is divided into three intervals, namely, the safe interval, the warning interval and the dangerous interval. Specifically, in the embodiment of the present invention, the above meteorological data and the corresponding interval values ​​are set as follows: the safe interval of humidity is , the warning interval is The danger zone is ; The safe range of wind speed is , the warning interval is The danger zone is ; The safe range of cloud cover is , the warning interval is The danger zone is The safety zone for rain and snow is "no rain and snow", and the warning zone and danger zone are both "rain and snow". Indicates the safe value of humidity, Indicates the dangerous value of humidity, Indicates the safe value of wind speed, Indicates the dangerous value of wind speed, Indicates the safe value of cloud cover, Indicates the dangerous value of cloud cover.

[0023] The values ​​of each interval endpoint are based on the meteorological conditions suitable for working when the telescope is calibrated at the factory. For example, when the telescope is calibrated at the factory, it needs to be calibrated at a humidity below , wind speed is lower than , cloud cover below It is most suitable to work under the condition of no rain or snow. The values ​​of different telescopes are different, but they are all known values. The embodiments of the present invention use 、 、 The endpoints of the safety interval are determined based on the actual conditions of the telescope. Humidity and wind speed are the maximum values ​​that ensure the telescope will not be damaged, while cloud cover is the maximum value that ensures normal observation of the telescope.

[0024] The significance of setting up the meteorological data interval group is that when the telescope is in the observation state (dome protective cover is fully open), if all meteorological data are in the safe range, the heating of the hydraulic support rod of the hydraulic open dome will be stopped; if a certain meteorological data is in the warning range, whether to heat the hydraulic support rod of the hydraulic open dome will be determined according to the air temperature; if a certain meteorological data is in the danger range, the dome protective cover will be closed.

[0025] Since the telescope's working location and climate are different, the meteorological data will be different. Therefore, the meteorological data should be determined according to the climatic characteristics of the telescope's working location and is not limited to the above four types. If necessary, temperature, PM2.5, PM10, etc. can be added or reduced.

[0026] Visible light telescopes are usually used for observations at night, and the observable period is usually expressed as the sun at a certain elevation angle or below, that is, ,in, represents the sun's pitch angle, Indicates the maximum solar pitch angle of the telescope at night. , which can be calculated using the station coordinates and time information. The calculation method has open source code. The maximum solar pitch angle of the telescope at night is The telescope manufacturer calibrates the telescope during installation. The final calibration value is related to factors such as the topography, longitude and latitude of the telescope site, and the optical system of the telescope. It is not a uniform value. The calibration method is as follows: Set the exposure time used for normal telescope observations to .

[0027] On a clear night, when the sun has just set below the horizon, the sun's pitch angle at this time is recorded as , turn the telescope's elevation angle to a higher position (e.g. the elevation angle is greater than 80°), and set the camera exposure time to , collect images through the camera, starting from the first frame of unsaturated image generated by the camera, record the average pixel grayscale value of each frame image and the solar pitch angle at the exposure time of the frame image, and record continuously for 1 hour. The minimum value of the average pixel grayscale value sequence of the image is recorded as , traverse the image pixel gray value average sequence in chronological order, and the average gray value of a frame of image captured by the camera appears for the first time Meet the conditions ,in, represents the coefficient and ,For example , the solar pitch angle corresponding to the exposure moment of the frame image is recorded as .

[0028] In the early morning hours, when the sun is about to rise from the horizon, record the sun's pitch angle. . Make the following judgment: If ,but ,otherwise .

[0029] If the terrain around the telescope site varies greatly, recalibration can be done regularly.

[0030] The specific control process of the hydraulic open dome is as follows: Calculate the current solar pitch angle ,like , indicating that the solar pitch angle is greater than the maximum solar pitch angle of the telescope at night, then the daytime control process is executed. , it means that the solar pitch angle is not greater than the maximum solar pitch angle of the telescope at night, and the night control process is executed.

[0031] Attachment Figure 1 The second-level timer trigger means that the process of the embodiment of the present invention is triggered by the second-level timer. The second-level timer is used to trigger the process once every second or several seconds. When the process is triggered, the corresponding current time is output and the solar pitch angle is calculated in combination with the location of the telescope. .

[0032] like Figure 2 As shown, the daytime control process is: After determining that the daytime control process is executed, the meteorological data at this time is judged: If at least any one of the meteorological data is not within the safe range, the heating of the hydraulic strut is stopped; If the meteorological data are all within the safe range, calculate the maximum solar pitch angle when the sun sets to the telescope for nighttime observation. Time :like , then start heating the hydraulic support rod; if , then open the dome protective cover; Among them, Indicates the current time. The hydraulic oil in the hydraulic strut will become viscous or solidified when the temperature is too low. When the hydraulic open dome is opening or closing the dome protective cover, the temperature of the hydraulic oil in the hydraulic strut needs to be higher than its required minimum operating temperature. Indicates the time required to heat the hydraulic strut to the minimum operating temperature.

[0033] like Figure 3 As shown, the night control process is: After the night control process is executed, the time required for the hydraulic strut to heat up at the current temperature is calculated based on the temperature. , judge the status of the dome protective cover at this time: When the dome protective cover is not open: if at least one of the meteorological data is not within the safe range, the hydraulic strut will stop heating; if all the meteorological data are within the safe range, the hydraulic strut will start heating, and when the hydraulic strut heating time reaches , open the dome cover.

[0034] When the dome cover is open, calculate the time from the sun rising to the maximum solar pitch angle for nighttime observation of the telescope. Corresponding time , make the following judgment: when When the oil pressure rod is heated, , close the dome protection cover.

[0035] when When the meteorological data are all in the safe range, the oil pressure support rod is stopped from being heated; if at least any one of the meteorological data is not in the safe range, the oil pressure support rod is started to be heated; if at least any one of the meteorological data is in the dangerous range, the dome protective cover is closed.

[0036] Especially, when When , it indicates that the time required for heating the hydraulic support rod at the current temperature is 0, and the hydraulic support rod does not need to be heated. In this case, the hydraulic support rod is not heated.

[0037] To implement the above-mentioned control method for the hydraulic open dome, an embodiment of the present invention further provides a control system for the hydraulic open dome, comprising a hydraulic open dome, a meteorological instrument, and an intelligent control system. The hydraulic open dome includes electric heating, hydraulic support rods, a dome controller, and a dome protective cover.

[0038] The hydraulic open dome is responsible for protecting the telescope. When the telescope is observing, the dome protection cover of the hydraulic open dome is fully opened, and the telescope can , pitch angle There is no obstruction in the observation range. When the telescope is in the non-observation period or the meteorological data does not meet the observation conditions, the dome protective cover can be completely closed to protect the telescope. Figure 4 The dome protective cover in the figure is for illustration only and does not mean that the actual hydraulic open dome has only two dome protective covers, nor does it mean that the actual dome protective cover is completely above the telescope.

[0039] The dome controller is connected to the hydraulic struts. It controls the extension and retraction of the hydraulic struts, thereby controlling the closing and opening of the dome cover. The hydraulic oil inside the hydraulic struts can become viscous or solidify in low temperatures, preventing the dome cover from closing or opening. Figure 4 The two hydraulic struts marked in the figure are for reference only and do not mean that a real hydraulic open dome has only two hydraulic struts. The specific number of hydraulic struts shall be designed and installed by the dome manufacturer based on actual conditions.

[0040] The electric heat trace is spatially connected to the hydraulic struts. If the dome controller sets the electric heat trace to active, it heats itself and transfers heat through the hydraulic struts to the hydraulic oil, heating it to a working state. If the dome controller sets the electric heat trace to inactive, it stops heating, eliminating energy loss. Typically, dome manufacturers provide a pre-calibrated function relationship between electric heat trace heating time and air temperature. The intelligent control system uses the air temperature data sent by the meteorological temperature sensor and this function relationship to determine the corresponding electric heat trace heating time. Figure 4 The two electric heat traces are for illustration purposes only and do not indicate that a hydraulic open dome will have only two electric heat traces. The specific number of electric heat traces will be designed and installed by the dome manufacturer based on actual conditions. The heated hydraulic struts described in this embodiment of the present invention are heated by electric heat traces to heat the hydraulic struts, ultimately heating the hydraulic oil within them.

[0041] The dome controller is connected to the intelligent control system, and there is data communication between the two. The intelligent control system sends instructions such as "start electric heating", "stop electric heating", "open the dome protective cover", and "close the dome protective cover" to the dome controller according to actual conditions. The dome controller performs corresponding control actions on the hydraulic open dome according to the received control instructions.

[0042] The meteorological instrument is installed on the outside of the hydraulic open dome and connected to the intelligent control system, with data communication also occurring between the two. The meteorological instrument involved in the embodiments of the present invention primarily includes a temperature sensor, a humidity sensor, a wind speed sensor, a rain and snow sensor, and a cloud meter. The meteorological instrument transmits meteorological data to the intelligent control system in real time. The temperature sensor transmits temperature in degrees Celsius, the humidity sensor transmits humidity in percentage, the wind speed sensor transmits wind speed in meters per second, the rain and snow sensor transmits the presence or absence of rain and snow, and the cloud meter transmits cloud cover percentage. If any meteorological data reported by the meteorological instrument falls within the danger zone for that data, the dome protective cover must be closed promptly to protect the telescope.

[0043] The intelligent control system can calculate the solar pitch angle based on the current station coordinates and time information , the sun sets to the maximum solar pitch angle for nighttime observations with the telescope Time , The time required to heat the hydraulic support rod to the minimum operating temperature As the sun rises to the maximum solar pitch angle for nighttime observations by the telescope Time required The system uses weather data to determine whether to start or stop the electric heating system and whether to open or close the dome cover, thereby achieving intelligent control of the hydraulic open dome. The intelligent control system can be installed on the outside or inside of the hydraulic open dome.

[0044] The embodiment of the present invention is verified by taking a 10-meter open dome protecting a 2.5-meter telescope at an observation station as an example: The meteorological data interval is set to: the safe range of humidity is , the warning interval is The danger zone is ; The safe range of wind speed is , the warning interval is The danger zone is ; The safe range of cloud cover is , the warning interval is The danger zone is The safe zone for rain and snow is "no rain and snow", the warning zone and danger zone are both "rain and snow", and the maximum solar pitch angle of the telescope at night , the function of electric heating time relative to air temperature is expressed as: , in, Indicates the current air temperature data fed back by the weather instrument. Indicates the time required for electric heating to heat the hydraulic oil in the hydraulic support rod to the minimum temperature required for operation. , .

[0045] The heating time function usually has a certain fault tolerance. For example, according to the heating time function, if the sun is about to set before the maximum solar pitch angle of the telescope at night ( ), the temperature is 10.1℃, there is no need to start the electric heating, and the sun sets when the telescope has the maximum solar pitch angle for nighttime observation ( ), the air temperature is 9.9°C. At this time, the electric heat trace requires 10 minutes of heating, but it may take less than 10 minutes. This error is factored into the electric heat trace heating time function and does not affect the opening or closing of the dome cover. In this embodiment of the present invention, if the air temperature is greater than 10°C, even if the process includes a step to start the electric heat trace, it is not actually necessary to start the electric heat trace.

[0046] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.

[0047] The above specific embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
