6, the system runs as follows, an operator operates through the human-computer interaction touch terminal 50 and is used for sending an operation instruction to the PLC 40, the PLC 40 is communicated with the turbidity probe 30 in the coral cylinder, a turbidity real-time value is read, a set value is substituted into an algorithm calculation result, and then the start, stop and rotating speed of the sample injection peristaltic pump 60 are controlled so as to keep the turbidity of the water body in the coral cylinder within a set range; meanwhile, the PLC controller 40 controls the stirring pump 70 to circulate the liquid in the turbidity standard solution cup 10.
The system is a set of turbidity real-time automatic balance control system, the PLC is communicated with a turbidity probe in the coral cylinder, a turbidity real-time value is read, a set value is substituted into a fuzzy algorithm calculation result, and then the start, stop and rotating speed of the sample injection peristaltic pump are controlled, so that the turbidity of the water body in the coral cylinder is kept within a set range. Because turbidity feedback in the coral jar can be lagged behind the application of sample process slightly, consequently chooses for use rotational speed adjustable peristaltic pump to control sampling system, avoid the application of sample too much, turbidity surpasss control range after the unrestrained ware of making fully mixes, leads to whole system out of control. The human interaction end adopts a 7-inch touch screen, a relatively visual operation picture is displayed after configuration, and after an operation instruction of the touch screen is issued, a PLC executes a specific flow to complete response. In order to meet the requirement of cloud operation, the 4G communication module is arranged in the HMI model selection, and after the Internet of things card is installed to enable the equipment to be online, a user can perform remote operation and data query on the system through an APP or a WeChat applet installed on a mobile phone. The turbidity standard solution conveyed into the coral cylinder must be constant, otherwise, the sampling algorithm is easily influenced, therefore, a stirring pump (circular pumping) is designed for the turbidity standard solution cup, when the sample needs to be added into the coral cylinder, the stirring pump is started firstly, the sample adding is started after a little delay, and the operation is kept in the whole process.
