Problems solved by technology
However, the working method of the "ground-based UV-absorbing aerosol monitor" not only needs to realize the observation of direct sunlight, but also needs to realize the observation of scattered light from the sky, and the working process is relatively complicated.
The traditional control system is difficult to meet the interface requirements of multiple components inside the instrument, and cannot guarantee the operating efficiency and reliability of the instrument

Embodiment Construction
[0026] The control system and control method of a ground-based ultraviolet-absorbing aerosol monitor according to the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] The connection relationship between the hardware main structure and the control system of the ground-based ultraviolet-absorbing aerosol monitor applicable to the present invention is as follows figure 1 As shown, the main structure of the instrument includes telescopes, detectors, power modules, sun trackers and environmental monitoring equipment. Among them, the telescope mainly completes the selection of the scattered light in the sky and the direct sunlight, and transmits the optical signal received by the telescope to the detector through the optical fiber; the detector selects the optical signal in the ultraviolet-visible band through the built-in spectrometer after spectroscopic processing, and then is detected by the CCD. capture; ...

The invention provides a control system and a control method for a foundation-ultraviolet absorptive aerosol monitor. The control system comprises a processor, a data acquisition card, a router and a wiring box, wherein the processor is connected with a solar tracker by the router, and is connected with and controls a spectrometer and a CCD (Charge Coupled Device) by a USB2.0 interface arranged; the data acquisition card is connected with a telescope and environmental monitoring equipment by an IO (Input / Output) interface arranged on the wiring box, and is used for transmitting signals outputted by the telescope and the environment monitoring equipment into the processor, receiving a control signal outputted by the processor, and then inputting the control signal into the telescope and the environment monitoring equipment to execute corresponding operations. The control system and the control method provided by the invention have the advantages that the problem of interface disorder caused by parallel control of multiple equipment is overcome, full-automatic running of the 'foundation-ultraviolet absorptive aerosol monitor' can be realized, and the control efficiency and the running stability for the monitor are improved.
Description
technical field [0001] The invention relates to the field of automatic control of monitors, in particular to a control system and a control method of a ground-based ultraviolet-absorbing aerosol monitor. Background technique [0002] In the field of instrument control system design, commonly used controllers include single-chip microcomputers and FPGAs. Their control principles are similar, but the richness of functions and interfaces is quite different. For example, the memory capacity of single-chip microcomputer is small and only has basic IO ports, which is only suitable for simple control of a few components, while FPGA has a large memory capacity, but the control The logic is relatively complex, and it is prone to control timing errors, which will affect the stability of the controlled equipment. [0003] The "ground-based UV-absorbing aerosol monitor" developed by the National Space Science Center of the Chinese Academy of Sciences retrieves UV-absorbing aerosol para...
