At 10:44 Beijing time on June 5, 2022, a glorious moment that captured the attention of millions. At this moment, China's Shenzhou-14 spacecraft, carrying 3 astronauts, lifted off from the Jiuquan Satellite Launch Center deep in the Gobi Desert, soaring straight into the sky, successfully sending the astronauts to the distant space. This manned spacecraft, carrying glory and dreams, embodies the wisdom and sweat of scientific research elites, including those in the field of precision instruments and meters technology. In the Shenzhou-14 spacecraft, there are various types of multi-functional precision instruments and meters, including important subsystems such as instrumentation and lighting. These precision instruments, full of cutting-edge technologies, are responsible for maintaining the normal on-orbit operation of the spacecraft and the safety of astronauts, playing an important role in safeguarding the Shenzhou-14 manned spacecraft and the astronauts. Shenzhou-14 is the 23rd spacecraft developed by the Fifth Academy of China Aerospace Science and Technology Corporation for China's manned space engineering, and it is also the 9th time that the Shenzhou series of spacecraft has performed a manned space mission. Achieving multiple "firsts" Shenzhou-14 manned spacecraft will achieve multiple "firsts" - Shenzhou-14 is the first manned mission after China's space station task entered the construction phase. During the on-orbit operation of Shenzhou-14 and the space station, it will welcome the "visit" of other spacecraft (Wentian experimental module, Mengtian experimental module, Tianzhou-5 cargo spacecraft, Shenzhou-15 manned spacecraft) for the first time. The Shenzhou-14 astronaut crew will personally witness and promote the expansion of the Chinese people's space home. Shenzhou-14 will welcome the docking of Shenzhou-15 spacecraft with the space station in space, realizing for the first time that two manned spacecraft are in orbit at the same time. Shenzhou-14 will realize the on-orbit rotation of astronaut crews for the first time. The astronaut crews of Shenzhou-14 and Shenzhou-15 will be stationed in orbit at the same time, and 6 Chinese astronauts will gather in space to witness new miracles in the journey of pursuing dreams in space. It is worth mentioning that Shenzhou-14, as the emergency rescue spacecraft for Shenzhou-13, entered the Jiuquan Satellite Launch Center in August 2021, setting a record of standing by for 7 months for the first time. For this reason, the Fifth Academy of China Aerospace Science and Technology Corporation carried out the "Beijing-Jiuquan" remote launch site inspection work for the first time, verifying the effectiveness of the "one ship launching, one ship standing by" mode, which will strongly support the need for the regular launch of Shenzhou spacecraft "two per year". Spacecraft control instruments: all-in-one like a universal tool In order for the Shenzhou-14 manned spacecraft to successfully complete this space mission, astronauts must use sophisticated instruments such as powerful display and control, voice, and manual control instruments to operate the spacecraft. The manufacturer of China's manned spacecraft instrument equipment has "customized" a variety of complete and fully functional precision instruments and equipment such as in-cabin display and control, voice, and manual control for the Shenzhou-14 manned spacecraft, which seem to be universal. Specifically, it mainly covers the following types of control instruments: Spacecraft terminal display instruments: clear display of information at a glance As the integrated display unit and time unit, the spacecraft terminal display instruments provide astronauts with the display of parameters, events, AD acquisition data, time information and other contents of each subsystem during the operation of the spacecraft, and are equipped with emergency event light windows for auxiliary display. Spacecraft terminal voice instruments: warm reminders with a word As the sound-generating unit, the spacecraft terminal voice instruments provide astronauts with prompts for important events and flight plans during the operation of the spacecraft, as well as voice broadcasts of various alarm information. Spacecraft manual control terminal instruments: stable control with a touch As the manual left/right panel unit, the spacecraft manual control terminal instruments provide astronauts with a dedicated control panel for manual control of GNC during flight, supporting the sending of manual motion control commands. The coding command equipment, as the spacecraft terminal control instrument, provides astronauts with the necessary human-machine interface for manipulating and controlling the spacecraft, supporting the input of manual command set control data. The manual right cabin wall unit and switch command panel provide astronauts with the necessary control interface when they are restrained in spacesuits during the flight of the spacecraft, and have sound and light feedback functions. Spacecraft instrument controller application software: intelligent and precise management with one click The instrument controller application software belonging to the instrument and lighting subsystem of the Shenzhou-14 manned spacecraft, although it seems invisible and intangible, plays a crucial role. It is like a "super intelligent administrator", perfectly performing the important role of human-computer dialogue. All parameter contents of many subsystems on the Shenzhou-14 spacecraft must be forwarded to the spacecraft instruments through the data management subsystem for clear display. The "super intelligent administrator" - the instrument controller application software plays an extraordinary role in converting these complex parameters into intuitive values that astronauts can grasp. The data generated by the operation of each subsystem of the Shenzhou-14 spacecraft is collected in the data management subsystem, and the "super intelligent administrator" - the instrument controller application software summarizes the data, converts it into content that astronauts can intuitively identify and operate, and displays it accurately on the instruments. Thus, astronauts can understand all parameters related to the spacecraft at a glance through the instruments on the spacecraft, and keep abreast of the operation status of each subsystem of the spacecraft. There are dozens of pages on the Shenzhou-14 spacecraft that timely display the situation of each subsystem of the spacecraft, and according to the needs of the manned rendezvous and docking mission, display many related contents including the physical condition of astronauts and world maps. All these are realized by the "super intelligent administrator" - the instrument controller application software. The instrument controller application software adopts unique graphic display technology, displaying the spacecraft's trajectory, attitude, flight status and information of each subsystem through graphics, text, animation and other methods. With this unique graphic and text display technology, it can not only present a novel display effect of the instrument controller, but also realize the processing and display of graphics and text in the space intelligent instrument, providing astronauts with a comfortable, convenient, clear and intuitive display interface for performing tasks. Spacecraft cabin door rapid leak detector: precise detection for peace of mind In the space station mission, astronauts need to enter the core module of the space station from the Shenzhou-14 spacecraft, during which they have to go through multiple cabin penetration activities, all of which require opening and closing the cabin door. At this time, the gas that maintains the survival of astronauts in the cabin must not leak, so the sealing of the cabin door is crucial, and thus the rapid and accurate detection of the tightness of the cabin door is particularly important. Therefore, the cabin door rapid leak detector can be called a precious "magic tool" to ensure the safety of astronauts when leaving the cabin. The function of the cabin door leak detector is to detect whether the cabin door of the Shenzhou spacecraft is sealed. Relying on the core sensing system inside the instrument, it accurately senses changes in pressure and temperature, quickly judges whether the cabin door is closed properly in a very short time, and provides astronauts with the instruction "the cabin door is closed, you can take off the spacesuit", allowing astronauts to safely control the Shenzhou-14 spacecraft to pursue dreams in the sky, providing reliable safety guarantees for astronauts' activities in the cabin. Spacecraft instrument panel shock absorber: stable operation with calmness As the load-bearing component of the spacecraft instrument equipment, the overall frame structure of the instrument panel is like a "house". It not only provides independent "private space" for "family members" such as instrument display equipment and main manual control equipment, but also provides accurate and reliable installation interfaces for them. This "house" - the instrument panel is reliably connected to the spacecraft cabin wall through metal rubber shock absorbers. The metal rubber shock absorber is like a "safety guard in soft armor", which has both the inherent characteristics of metal and the unique elasticity of rubber, fully ensuring the stable and reliable operation of the instrument equipment. Once the spacecraft encounters strong vibration and impact during launch, flight and return, the metal rubber shock absorber can provide a necessary and reliable mechanical working environment for the instruments and equipment on the spacecraft. For example, during the flight of the spacecraft, it optimizes the mechanical working environment of the equipment on the instrument panel; and during the launch and return of the spacecraft, it ensures that the equipment is intact.
