This system uses 485 Net and EtherNet as the communication network. The monitor and control(More)
This paper designs an stepper motor control system apply to blood coagulation analyzer, which mainly includes the design of the hardware of nodes in slave machine, the communication program and motor control program and software in host machine. Combining with the CAN bus, the system uses MC9S12XS128 micro controller as control core and SLA7078MR as drive(More)
The article designs the detection method of automatic coagulation based on C# software, to achieve the parameter tests of Thrombus and Hemostatic. The article focuses on structure of the coagulation analyzer and the specific functions of the software design. Then it gives the communication protocol between upper and lower computer, and user interface design(More)
Soft sensing method was proposed for determination of effluent BOD from SBR and its principle was introduced, the method was based on the radial basic function (RBF) artificial neural network. The RBF neural network was trained and simulated by a lot of observed data, and the result showed that the RBF neural network may be used to fulfil soft sensing for(More)
A new algorithm of data processing and a method of soft sensor based on process neural network (PNN) for time-varying system are represented in the paper. Process neural network is an extension of traditional neural network, in which the inputs and outputs are time-variation. An aggregation operator is introduced to process neuron, and it makes the neuron(More)
Process neural network (PNN) is a new type of artificial neural network studied in recent year. PNN is an extent of traditional neural network, in which the inputs and outputs may be time-variation. Some modified algorithms for raising the training speed of PNN were investigated emphatically. These algorithms were based on function orthogonal basis(More)
