本发明涉及航天领域，在月球环境中工作的探测载荷领域，尤其涉及一种车载非接触式测量月球表面电位的装置。The invention relates to the field of aerospace, the field of detection loads working in the lunar environment, in particular to a vehicle-mounted non-contact device for measuring the potential of the lunar surface.
背景技术Background technique
未来随着月球探测的开展，我国的月球车和航天员将会在月球表面开展相关科学探索和研究。相关研究表明，月球表面电位在夜间和白天存在巨大的差别。月球表面存在的种类繁多月表地形地势，也影响着月球表面电位的分布。月表表面电位及其变化对航天员在月球环境中的安全活动至关重要。航天员乘坐月球车在月面行动过程中下车活动的情况下，当航天员接触这些位置时，电位很可能会对航天员产生放电效应，威胁到航天员的安全。因此，需要一种能够车载可移动的非接触式测量月球表面电位的装置，获得真实可靠的月表电位，为航天员安全的月面活动提供数据参考。In the future, with the development of lunar exploration, my country's lunar rovers and astronauts will carry out related scientific exploration and research on the lunar surface. Relevant studies have shown that there is a huge difference in the lunar surface potential at night and during the day. There are many kinds of lunar surface topography and topography on the lunar surface, which also affects the distribution of the potential on the lunar surface. The lunar surface potential and its changes are critical to the safe activities of astronauts in the lunar environment. When the astronauts take the lunar rover and get off the vehicle during the lunar surface operations, when the astronauts touch these positions, the electric potential may have a discharge effect on the astronauts, threatening the safety of the astronauts. Therefore, there is a need for a vehicle-mounted and movable non-contact device for measuring the potential of the lunar surface, so as to obtain a real and reliable potential of the lunar surface, and provide a data reference for the safe lunar surface activities of astronauts.
月球表面覆盖着一层风化层，即月壤。由于空间带电粒子的作用，使得月壤带有大量电荷，从而形成月表电位。物体表面的电位本质是电荷的累积形成电势，如果采用接触式的测量不可避免的会产生累积电荷的放电，改变待测表面的电位，造成测量的结果失真。因此，需要采用非接触式的方法，以获得真实的月球表面电位。The lunar surface is covered with a layer of regolith, the lunar regolith. Due to the action of space-charged particles, the lunar soil has a large amount of electric charge, thus forming the lunar surface potential. The potential of the surface of the object is essentially the potential formed by the accumulation of charges. If the contact measurement is used, the discharge of the accumulated charges will inevitably occur, which will change the potential of the surface to be measured and cause the measurement results to be distorted. Therefore, a non-contact method is required to obtain the real lunar surface potential.
由于月球表面存在月尘等环境，传统的非接触式测量方法，并不适用于月球表面的探测。传统的非接触式测量通常有以下几种：电容感应式、振动电容式以及集电式。电容感应式电位测量装置如图1所示，测量的基本原理是利用探头与被测带电体之间存在的电容，感应到被测电位后，获得电容的静电电压，从而获得被测电位。但是，电容感应式工作的前提是，探头与被测带电体之间必须为真空状态。当两个电极之间存在带电粒子时，该方法失效。而在月表存在月尘等离子体，因此电容感应式的非接触测量方式不适用于月表探测。振动电容式电位测量装置如图2所示，测量的工作原理是探头是一可振动的金属片，通过设定的机械振动，探头与被测带电体之间的电容周期性地变化，于是，在被测带电体静电感应的作用下，在探头上产生一个周期性变化的电压信号，从而获得被测电位。振动电容式的基本原理和电容感应式相同，当两个电极之间存在带电粒子时，该方法失效。因此，振动电容式的非接触测量方式不适用于月表探测。Due to the existence of lunar dust and other environments on the lunar surface, traditional non-contact measurement methods are not suitable for the detection of the lunar surface. Traditional non-contact measurements are usually of the following types: capacitive inductive, vibrating capacitive, and collector. Capacitance inductive potential measuring device is shown in Figure 1. The basic principle of measurement is to use the capacitance existing between the probe and the charged body to be measured to obtain the electrostatic voltage of the capacitance after sensing the potential to be measured, thereby obtaining the potential to be measured. However, the premise of capacitive induction operation is that the space between the probe and the charged body to be measured must be in a vacuum state. This method fails when charged particles are present between the two electrodes. However, there is lunar dust plasma on the lunar surface, so the capacitive inductive non-contact measurement method is not suitable for lunar surface detection. The vibrating capacitive potential measuring device is shown in Figure 2. The working principle of the measurement is that the probe is a vibrating metal sheet. Through the set mechanical vibration, the capacitance between the probe and the charged body to be measured changes periodically, so, Under the action of the electrostatic induction of the charged body to be measured, a periodically changing voltage signal is generated on the probe to obtain the measured potential. The basic principle of the vibrating capacitive method is the same as that of the capacitive inductive method. When there are charged particles between the two electrodes, the method fails. Therefore, the vibration-capacitive non-contact measurement method is not suitable for lunar surface detection.
集电式测量的工作原理是利用放射性同位素使空气电离，在放射性同位素作用下，空气被电离，在被测带电体与探头之间形成微弱的气体导电区域，在集电片上产生一个直流电压信号，从而获得被测电位。放射性会对航天员有伤害。另外，月表无大气，不具备空气电离的前提条件，集电势测量方式也不适用于月表探测。The working principle of collector measurement is to use radioisotopes to ionize the air. Under the action of radioisotopes, the air is ionized, and a weak gas conduction area is formed between the charged body and the probe to be measured, and a DC voltage signal is generated on the collector sheet. , so as to obtain the measured potential. Radioactivity can harm astronauts. In addition, the lunar surface has no atmosphere and does not have the prerequisites for air ionization, and the collecting potential measurement method is not suitable for lunar surface detection.
另外，为实现一定区域的月表表面电位测量，该技术不能是固定点式的测量技术，应能够车载，利用月球车在月表的移动，从而实现区域范围内的月表电位测量。In addition, in order to realize the potential measurement of the lunar surface in a certain area, the technology cannot be a fixed-point measurement technology.

具体实施方式Detailed ways
下面结合附图对本发明的技术方案进行详细的说明。The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.
月球表面为非良导体，不导电。因此，月球不存在类似地球大地的“零电位”的概念。通常，月表表面的“零电位”是指月球鞘层以外“无穷远处”的背景等离子体电位。因此，真实的月表电位是指相对于“无穷远处”的背景等离子体的电位差。The lunar surface is a bad conductor and does not conduct electricity. Therefore, the moon does not have the concept of "zero potential" similar to the earth's earth. Typically, the "zero potential" on the lunar surface refers to the background plasma potential "at infinity" beyond the lunar sheath. Therefore, the true lunar surface potential refers to the potential difference relative to the background plasma "at infinity".
为实现上述真实的月表电位测量，本发明提出了一种车载非接触式测量月球表面电位的装置，该装置由非接触式测量探头、月表电位测量电路、以及支架和温控多层组成，如图3所示。In order to realize the above-mentioned true lunar surface potential measurement, the present invention proposes a vehicle-mounted non-contact device for measuring the lunar surface potential. The device is composed of a non-contact measurement probe, a lunar surface potential measurement circuit, a bracket and a temperature control multilayer. ,As shown in Figure 3.
该装置以月球车为“地”，测量获得月表表面相对于月球车的电位V1。再通过内部电位基准测量电路获得月球车相对“无穷远处”的背景等离子体的电位V2。The device uses the lunar rover as the "ground", and measures the potential V1 of the lunar surface relative to the lunar rover. Then, the potential V2 of the lunar rover relative to the background plasma at "infinity" is obtained through the internal potential reference measurement circuit.
即可获得真实的月表电位V＝V1+V2；The real moon surface potential V=V1+V2 can be obtained;
随着月球车的移动，实时获取V1和V2，即可实现对区域内月表电位的非接触式探测。With the movement of the lunar rover, V1 and V2 can be acquired in real time, and the non-contact detection of the potential of the lunar surface in the region can be realized.
该装置的工作原理：非接触式测量探头主动发射能量可控、能量扫描的带电粒子束，通过接收带电粒子的反射，实现对充电电位的测量。即通过向待测月表表面发射能量可控、能量扫描的带电粒子束。当带电粒子束的能量小于月表电位的势能时，带电粒子束会被发射。当带电粒子束的能量大于月表电位的势能时，带电粒子束会到达月表，被月表吸收，不发生发射。由于已知发射带电粒子束的能量，通过监测带电粒子的反射状态，在反射和不反射的临界处，此时的带电粒子能量值就表示了此时的月表表面电位。The working principle of the device: the non-contact measuring probe actively emits a charged particle beam with controllable energy and energy scanning, and realizes the measurement of the charging potential by receiving the reflection of the charged particle. That is, a charged particle beam with controllable energy and energy scanning is emitted to the lunar surface to be measured. Charged particle beams are emitted when their energy is less than the potential energy of the lunar surface potential. When the energy of the charged particle beam is greater than the potential energy of the potential on the lunar surface, the charged particle beam will reach the lunar surface and be absorbed by the lunar surface without emission. Since the energy of the emitted charged particle beam is known, by monitoring the reflection state of the charged particle, at the critical point of reflection and non-reflection, the charged particle energy value at this time represents the surface potential of the lunar surface at this time.
当月表带正电时，非接触式测量探头主动发射离子，如图4所示。When the moon watch is positively charged, the non-contact measuring probe actively emits ions, as shown in Figure 4.
当月表带负电时，非接触式测量探头主动发射电子，如图5所示。When the moon watch is negatively charged, the non-contact measuring probe actively emits electrons, as shown in Figure 5.
非接触式测量探头包括带电粒子发射器和反射粒子接收器，如图6所示。带电粒子发射器发射粒子束流，反射粒子接收器接收反射的带电粒子。由于月表表面不是理想的平面，实际会对发射的粒子造成散射，因此反射粒子接收器设计为圆弧形球面，以增大接收范围，防止接收不到散射角度较大的粒子。带电粒子发射器为圆柱形，位于反射粒子接收器的中心，下端开口为带电粒子发射窗口。The non-contact measurement probe consists of a charged particle transmitter and a reflective particle receiver, as shown in Figure 6. The charged particle emitter emits a beam of particles, and the reflective particle receiver receives the reflected charged particles. Since the surface of the lunar surface is not an ideal plane, it will actually cause scattering of the emitted particles, so the reflective particle receiver is designed as an arc-shaped spherical surface to increase the receiving range and prevent particles with large scattering angles from not being received. The charged particle emitter is cylindrical, located in the center of the reflective particle receiver, and the opening at the lower end is a charged particle emission window.
月表电位测量电路包括发射带电粒子能量控制电路、接收反射粒子电路、电位基准测量电路、逻辑控制电路及供电电路，如图7所示。主要功能是控制发射带电粒子的能量，从低到高进行扫描；并实时接收反射粒子的信号，判断反射粒子接收有、无的临界值；电位基准测量电路则实时测量月球车相对于“无穷远处”的背景等离子体的电位。The potential measurement circuit of the lunar surface includes an energy control circuit for emitting charged particles, a circuit for receiving reflected particles, a potential reference measurement circuit, a logic control circuit and a power supply circuit, as shown in Figure 7. The main function is to control the energy of the emitted charged particles, and scan from low to high; and to receive the signal of the reflected particles in real time, to determine the critical value of whether the reflected particles are received; the potential reference measurement circuit measures the lunar rover in real time relative to "infinity. the potential of the background plasma.
月表电位测量电路安装在月球车内部；支架起到支撑探头，并远离月球车的作用，减少月球车本体对探测的影响；非接触式测量探头与月表电位测量电路之间的连接电缆，安装在支架内部，避免月表环境的影响；温控多层起到对探头的温度控制作用，以适应月球昼夜温度的巨大变化。The lunar surface potential measurement circuit is installed inside the lunar rover; the bracket supports the probe and keeps it away from the lunar rover to reduce the influence of the lunar rover body on the detection; the connection cable between the non-contact measurement probe and the lunar surface potential measurement circuit, It is installed inside the bracket to avoid the influence of the lunar surface environment; the temperature control multi-layer plays a role in controlling the temperature of the probe to adapt to the huge changes in the lunar day and night temperature.
相关研究表明，月球在白天，由于受到光照的影响，月球表面会带正电；月球在夜间，由于受到电子充电的影响，月球表面会带负电。在实际应用过程中，可根据昼夜的变化，选择发射离子或电子。Relevant studies have shown that during the day, the moon's surface will be positively charged due to the influence of light; at night, the moon's surface will be negatively charged due to the influence of electron charging. In the actual application process, ions or electrons can be selected to be emitted according to the changes of day and night.
另外，由于月表地形地貌的遮挡，白天没有光照的山谷等区域也会带负电。因此，在实际应用过程中，可通过交替发射离子和电子，识别出特殊区域内表面电位的“正”或“负”。In addition, due to the occlusion of the topography of the lunar surface, areas such as valleys without sunlight during the day will also be negatively charged. Therefore, in practical applications, the "positive" or "negative" surface potential in a particular region can be identified by alternately emitting ions and electrons.
最后所应说明的是，以上实施例仅用以说明本发明的技术方案而非限制。尽管参照实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，对本发明的技术方案进行修改或者等同替换，都不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
