An interventional control method based on a computer control system. An interventional control system is designed on the basis of an original computer control system; the analog-to-digital conversion unit of the interventional control system receives a signal from the data acquisition module of the original computer control system and said signal is processed by a control processing unit according to a built-in program; then a digital-to-analog conversion unit performs digital-to-analog conversion on the signal output by the control processing unit and then outputs a signal obtained after the digital-to-analog conversion to the analog-to-digital conversion unit of the original computer control system. According to the interventional computer control system, on the basis of an original computer control system, the analog-to-digital conversion unit of the interventional control system receives a signal output from the data acquisition module of the original computer control system and control processing is performed on said output signal; then the digital-to-analog conversion unit of the interventional control system outputs a signal to the analog-to-digital conversion unit of the original computer control system. The function upgrade of an original computer control system is implemented without changing the operating program of the original computer control system.

A method for planar transformer with an odd turn ratio includes: determining a turn ratio and winding parameters of a transformer to be manufactured; if the turn ratio is odd, determining that there is respectively one winding turn on a first middle layer and a second middle layer and two winding turns on a top layer and a bottom layer; determining widths of winding wires on marginal layers as well as widths of winding wires on middle layers; winding and parallelly connecting an inner winding wire on the top layer to an inner winding wire on the bottom layer, and then serially connecting the parallel-connected inner winding wires to an outer winding wire to form a primary winding; and parallelly connecting the winding wire on the first middle layer to the winding wire on the second middle layer to form a secondary winding, so as to obtain the transformer.

Disclosed are a monitoring, prevention and management method for preventing a drilling pump from pump suffocation and misoperation, and a pump pressure protection system therefor. The monitoring method may comprise mounting a standpipe pressure sensor on a standpipe for detecting the pressure inside the standpipe; mounting a pump pressure sensor on a discharge line of the drilling pump for detecting the pressure of the drilling pump; setting a judgement constant N according to the average value of the difference between mud pressure in the pipelines upstream and downstream of a high-pressure valve in a normal operating condition; and at the start of the drill pump, comparing the mud pressure Pin the pipeline upstream of the high-pressure valve and the mud pressure Pin the pipeline downstream of the high-pressure valve in real time: if P-P&#x2264;N, the high-pressure valve is determined in an open state, and the drilling pump is operating normally; and if P&#x2212;P&#x3e;N, the high-pressure valve is determined in a closed state, and a pump suffocation occurs to the drilling pump. According to the method, whether the high-pressure valve is closed is determined by means of calculating and comparing the difference between upstream and downstream pressure of mud liquid using the pressure sensors, such that not only can a drilling pump be prevented from a pump seizure accident due to suffocation, but also a safety risk brought about by an ultra-high pump pressure of a drilling pump during drilling can be prevented by means of taking full advantages of the pressure sensors.
