具体实施方式detailed description
下面结合具体实施例和附图，对本发明技术方案进行清楚、完整地描述。The technical solution of the present invention will be clearly and completely described below in combination with specific embodiments and accompanying drawings.
如图1所示，本发明一种小体积数字化分子电子角加速度计，包括液环和数字电路；液环包括工作液体、环圈、毛细管、溶剂补偿器、电极和转换器；其中：环圈是外径为35mm，内径为34mm的环形管结构；环圈内充满工作液体，工作液体由丙酮或丙酮中添加甲苯等有机溶剂组成；溶剂补偿器是直径为5mm的球状结构，在溶剂补偿器内设置一根长度为2mm，直径为0.1mm的毛细管；毛细管的一端在溶剂补偿器内部，另一端与环圈相连通。As shown in Fig. 1, a kind of small-volume digital molecular electron angular accelerometer of the present invention comprises liquid ring and digital circuit; Liquid ring comprises working liquid, ring, capillary, solvent compensator, electrode and converter; Wherein: ring It is an annular pipe structure with an outer diameter of 35mm and an inner diameter of 34mm; the ring is filled with working liquid, which is composed of acetone or acetone with toluene and other organic solvents; the solvent compensator is a spherical structure with a diameter of 5mm. A capillary with a length of 2 mm and a diameter of 0.1 mm is arranged inside; one end of the capillary is inside the solvent compensator, and the other end communicates with the ring.
在本实施例中，环圈和溶剂补偿器连接在一起：环圈和溶剂补偿器的材料是玻璃时，环圈和溶剂补偿器通过熔结的方式连接在一起；环圈和溶剂补偿器的材料是不锈钢时，环圈和溶剂补偿器通过焊接的方式连接在一起。In this embodiment, the ring and the solvent compensator are connected together: when the material of the ring and the solvent compensator is glass, the ring and the solvent compensator are connected together by welding; When the material is stainless steel, the ring and solvent compensator are welded together.
当温度发生改变时，工作液体的体积发生改变，通过毛细管实现环圈内的工作液体与溶剂补偿器内的工作液体相互连通，填补因温度的变化产生的环圈内液体的体积变化(毛细管内径很小，气泡无法进入环圈内)。在环圈内镶嵌一片转换器，转换器是由绝缘材料烧结而成的具有毛细孔隙的材料，转换器两侧各设置一个惰性电极。When the temperature changes, the volume of the working liquid changes, and the working liquid in the ring and the working liquid in the solvent compensator communicate with each other through the capillary to fill the volume change of the liquid in the ring caused by the temperature change (the inner diameter of the capillary) are too small for air bubbles to enter the ring). A converter is embedded in the ring, and the converter is a material with capillary pores sintered from an insulating material, and an inert electrode is arranged on both sides of the converter.
在本实施例中，转换器材料为以下两种绝缘材料中的一种：硅酸盐玻璃、氧化物陶瓷；转换器材料的毛细孔隙直径为40～60μm，液体通过率为1～2N·S/㎡；转换器两侧设置的惰性电极为铂电极。In this embodiment, the converter material is one of the following two insulating materials: silicate glass and oxide ceramics; the capillary pore diameter of the converter material is 40-60 μm, and the liquid passage rate is 1-2 N·S /㎡; The inert electrodes set on both sides of the converter are platinum electrodes.
当工作液体充满转换器的毛细孔隙时，在转换器和工作液体的界面上由于相间电荷分离产生双电层，双电层中部分电荷与转换器非刚性连接，处于运动状态，导致在充满工作液体的转换器内毛细孔隙中存在大量的剩余单极带电离子，从而工作液体形成极性。当本产品液环内工作液体受到压力作用通过转换器时，这些离子被运动着的极性液体带动，在毛细孔隙中形成离子流，通过电极上的电化学反应，该离子流转变为金属导线电流，此电流经放大器的负载电阻输出电压值。When the working liquid fills the capillary pores of the converter, an electric double layer is formed on the interface between the converter and the working liquid due to the separation of phase charges, and part of the charges in the electric double layer are non-rigidly connected with the converter and are in a state of motion, resulting in full working There are a large number of residual unipolar charged ions in the capillary pores in the converter of the liquid, so that the working liquid forms a polarity. When the working liquid in the liquid ring of this product is under pressure and passes through the converter, these ions are driven by the moving polar liquid to form an ion flow in the capillary pores, and through the electrochemical reaction on the electrode, the ion flow is transformed into a metal wire Current, which outputs a voltage value through the load resistor of the amplifier.
电化学系统的过程可以用图2来描述，实际上是电极表面的双层电容充放电过程，即转换器的毛细孔隙中剩余单极带电离子因流动形成的离子流通过电极的电化学反应转换成导线的电流的这一过程。The process of the electrochemical system can be described in Figure 2. It is actually the charging and discharging process of the double-layer capacitance on the electrode surface, that is, the remaining unipolar charged ions in the capillary pores of the converter are converted by the electrochemical reaction of the electrode through the ion flow formed by the flow. This process of current flowing into a wire.
如图3所示，数字电路主要功能包括微弱电荷信号的模拟放大、模数转换和数字处理。考虑到噪声的因素，采用电荷放大电路和以ARM芯片为基础的数字电路相结合的方法。As shown in Figure 3, the main functions of the digital circuit include analog amplification, analog-to-digital conversion and digital processing of weak charge signals. Considering the noise factor, the method of combining the charge amplifier circuit and the digital circuit based on the ARM chip is adopted.
