[0003] Many residential and commercial air conditioning and refrigeration units use evaporator coils to dehumidify and cool the ambient air in homes, climate-controlled storage spaces, workspaces, etc. The evaporator coil is located indoors, above the occupied area of ​​the building it serves. When the condensate discharge line in the evaporator coil is blocked, the water level inside the pipe gradually rises due to the air conditioner body continuing to drain water through the pipe, resulting in a backflow phenomenon. In order to avoid irreparable damage to the internal parts of the air conditioner caused by the rising water, while effectively controlling the equipment to drain the accumulated liquid, an electronic water level control system is introduced.

[0020] The principle of the patent of this invention: The inductive digital water level sensor is designed according to the idea of ​​imitating biology and applying the design idea of ​​imitating neural network. Its interior is full of neuron circuit boards, and its exterior is cast from plastic insulating materials. It is generally made into a rod shape. The sensor emits detection signals into the water by an ultrasonic generator and a transmitter head, and receives the detection signals through the medium water by a number of sampling induction element circuits. The signal voltage obtained after detection by the capacitive coupling detection circuit realizes direct sampling of the water level signal, becoming a digital sampling sensor. Each of its neuron circuits outputs digital signals in the form of switching pulses. After statistics, the switching digital signals are modulated into analog signal current (non-standard current signals) and output to the signal conditioning circuit for further processing. The signal conditioning circuit converts the non-standard current signal output by the sensor into a voltage signal to prepare for analog-to-digital conversion. After analog-to-digital conversion by the single-chip microcomputer, the sensor signal can be converted into a digital signal, and then the following operations can be easily performed: storing hydrological data, outputting a standard current signal of 4 to 20 mA through AD421, and outputting through the RS-485 interface.
