Background technique
Current atmospheric electric field monitoring mode is dynamic monitoring, drives rotation by using a metal stationary plate and a motor
The open metal movable plate turned detects.Interaction is generated by the metal movable plate and atmospheric electric field of rotation, on metal stationary plate
Faint alternation induced voltage is generated, to monitor atmospheric electric field, detecting distance can achieve the distance other than dozens of kilometres, still
Structure is more complex, and mating computer is needed to use；Involve great expense (price of general model is in thousands of members)；Volume is difficult to reduce；It is right
Nearby the thunder and lightning electric field (in several meters to tens meters) cannot accurately judge.
Summary of the invention
The present invention is achieved by the following technical solution.
A kind of atmospheric electric field static monitoring techniques method, comprising the following steps:
Step 1: atmospheric electric field static monitoring techniques antenna (antenna, which can use, needs original equipment antenna to be protected to constitute,
Independent monitoring aerial can be separately provided) atmospheric electric field around real-time watch device, when ambient atmosphere voltage of electric field increases,
The either electric field of positive polarity or negative polarity can all induce a faint voltage letter on atmospheric electric field monitoring aerial
Number.
Step 2: the voltage signal sensed diode D1, diode D2, diode D3 and diode D4 by being made of
Bridge commutating；
Step 3: the signal after rectification is sent to by adjusting potentiometer R2 to be put by what field-effect tube MOS and resistance R1 were formed
Big circuit amplification, amplified signal are sent to subsequent conditioning circuit processing.
Between the input terminal and ground of scene effect pipe of the present invention, access one is played the capacitor C of Anti-Jamming, filters out antenna
The instantaneous interference signal of induction, and have the function of anti-instantaneous pressure pulse voltage, protect subsequent field-effect tube.The present invention
Between the input terminal and ground of scene effect pipe, a Zener diode TVS is accessed, conducting discharge voltage is 6V to 12V；This yuan
Part plays the role of similar to gas-discharge tube, and difference is that conducting discharge voltage is lower (protection equipment more reliable), can be than gas
Body discharge tube is faster connected, and the dual complex protection circuit of this circuit itself is collectively constituted with GDT.
The present invention has accessed lightning protection gas-discharge tube GDT between the lower end and ground of atmospheric electric field monitoring aerial, with protection
Observation circuit and subsequent conditioning circuit are not damaged by thunder and lightning.When the voltage that atmospheric electric field monitoring aerial senses is more than 75V
When, lightning protection gas-discharge tube automatic discharging, sensed high voltage of releasing, to protect subsequent conditioning circuit.
Since field-effect tube (MOS) is voltage-controlled device, input terminal hardly needs electric current, so, to faint
Voltage signal is very sensitive, so having used this characteristic of metal-oxide-semiconductor here and having made full use of, reaches low cost and high reliability prison
Survey the purpose of atmospheric electric field.
