Abstract

The invention discloses a medical oxygen production host PLC intelligent integrated control system comprising a power supply, an oxygen analyzer, a touch screen, relays and a program controller. One end of the power supply is provided with a fuse device which is connected with the oxygen analyzer. One side of the oxygen analyzer is provided with a rectification transformer which is provided with a first indicating lamp. The first indicating lamp is connected with the touch screen. The program controller is provided with a second indicating lamp, a third indicating lamp, a fourth indicating lamp and oxygen purity alarm. The relays comprise a first relay, a second relay and a third relay. The second indicating lamp and the third indicating lamp are connected with the first relay. The fourth indicating lamp is connected with the second relay. The third relay and the oxygen purity alarm are directly connected with the program controller which is provided with a carbon potential alerter, a first button switch and a second button switch. The program controller is connected with electromagnetic valves and pneumatic valves of each machine set of the oxygen production host.

Description

technical field [0001] The invention relates to a PLC intelligent joint control system for a medical oxygen generator. Background technique [0002] The PLC working process is generally divided into three stages, namely input sampling, user program execution and output refresh. The completion of the above three stages is called a scan cycle. The scanning speed repeats the above three stages. [0003] 1) Input sampling stage: In the input sampling stage, the programmable logic controller reads in all input states and data sequentially in a scanning manner, and stores them in the corresponding units in the I / O image area. After the input sampling is completed, it turns to the user program execution and output refresh stage. In these two stages, even if the input state and data change, the state and data of the corresponding unit in the I / O image area will not change. Therefore, if the input is a pulse signal, the width of the pulse signal must be greater than one scan period...
