Problems solved by technology
[0003] To solve this problem, the current common solutions in this field at home and abroad are limited to active (electrically driven insulation mechanism) or passive (insulation material) temperature compensation for molecular-electronic induction accelerometers to improve molecular-electronic induction at different temperatures. The output consistency of the accelerometer, that is, by controlling the temperature of the external working environment of the molecular-electronic induction accelerometer, the molecular-electronic induction accelerometer can work in a specific temperature wide environment. This method not only limits the molecular-electronic induction accelerometer The temperature range of the working environment of the accelerometer cannot effectively guarantee the consistency of the output of the molecular-electronic inductive accelerometer at different temperatures.

Embodiment Construction
[0061] The present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited by specific embodiments.
[0062] The molecular-electronic inductive accelerometer is composed of a reaction chamber (M.E.T. chamber), an electromagnetic feedback compensation system, a temperature compensation system, a signal acquisition / processing circuit, a power supply, and a housing package. The reaction chamber is the core component of the molecular-electronic inductive accelerometer, and its internal structure is as follows: figure 1 shown. Molecular-electronic inductive accelerometers usually adopt a single cylindrical reaction cavity structure, which includes an electrolyte sealed cavity, electrolyte, electrodes, insulating barriers, and wires, and electrodes and insulating barriers are usually integrated and packaged in the same chip , known as "Electrochemical Mechanism Inertial Sensing Element" (Sensing Element, hereinaf...

The invention provides a temperature compensating method used for a molecule-electron induction type accelerometer, belongs to the technical field of apparatus and instrument measurement control, and is used for solving the problem of the influence of temperature change on the output consistency of the molecule-electron induction type accelerometer. The method includes: firstly, establishing an ion migration model of the molecule-electron induction type accelerometer; then establishing amplitude frequency characteristics thereof through the ion migration model, and establishing a temperature sensor equivalent circuit model based on the amplitude frequency characteristics to derive a corresponding relation between the temperature change and amplitude frequency response characteristics of the temperature sensor equivalent circuit model; and finally, establishing an amplitude frequency correction link according to the corresponding relation. According to the method, the work temperature width of the molecule-electron induction type accelerometer can be effectively increased, and the influence of the temperature change on the output consistency of the molecule-electron induction type by temperature change is effectively reduced.
Description
technical field [0001] The invention relates to a temperature compensation method for a molecular-electronic induction accelerometer, which belongs to the technical field of instrumentation measurement control technology. Background technique [0002] The consistency of the output of the molecular-electronic inductive accelerometer at different temperatures directly affects its performance index. Among them, the thermodynamic noise caused by the internal temperature difference of the electrolyte in the reaction chamber coupled in the original signal output is one of the main reasons for affecting the output consistency at different temperatures and resulting in inconsistent output signals at different temperatures. Based on the equivalent circuit of the molecular-electronic inductive accelerometer, the influence of different temperatures on its amplitude-frequency characteristics is established, and then the output consistency at different temperatures is improved through am...
