Detailed description of the invention
Fig. 1 is system structure diagram of the invention.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in Figure 1, a kind of circuit breaker multichannel Durable test system, has two group interfaces, it is respectively used to electrical durable
With mechanical durable connection.Every group interface is divided into 3 tunnels, can detect simultaneously to 3 samples.It is every to be divided into 3 branch again all the way
Road carries out the matching of related load to the product with multiple-channel output.9 branches are equipped with independent acquisition port, Ke Yijin
Monitoring under row load and light condition.It include: PLC control module, analogue collection module, human-computer interface module.
The PLC control module uses 224 XPCN type CPU, 24 I/O point capacity is shared, including 14 digital quantities
Input port and 10 digital quantity output ports.2 analog input ports, 1 analog output end are also integrated on ontology
Mouth and 2 RS-485 communication interfaces.The I/O terminal block of composition can easily carry out integral demounting.CPU224 has 13
The program of KB and data storage area space, 6 independent 30kHz the independent 20kHz of high-speed counter, two-way high-speed pulse
Output, PID controller, point-to-point interface communication protocol, multipoint interface communication protocol and free communication mouth.In addition system also configures
One EM231 analog input expansion module has 12,4 tunnel Analog input mModule, using Differential Input, maximum input
Voltage DC30V, maximum input current 32mA.
The analogue collection module uses the acquisition that sensor carries out current-mode analog quantity.Sensor is imitated based on Hall
It answers and magnetic field equilibrium principle, the measurement of electric current is carried out using cordless.Often identifying in control loop has electric current to pass through, by
Outer connecting resistance can get voltage signal.PLC is judged that work times add 1 according to the signal of feedback.If failing, therefore
Barrier number adds 1, when the number of stoppages reaches 5 times, then stops road movement, wait fault clearance.
The human-computer interface module uses SIMATICMP377 type multifunctional panel, and the peak performance for being able to satisfy design is wanted
It asks.12 " TFT screen is shown, touch operation is, it can be achieved that operator's control and monitoring and the visualization of complex machines.256 colors
Vector graphics display function, figure library facility, process values and information file function, the powerful curve graph function of pageable and scaling
It is complete.
Panel uses the soft sim ATICWinCCflexible 2008 based on Windows, can on PC direct simulation group
State is not necessarily to PLC and MP, is simple and efficient.7 database of central access STEP when Integrated automation passes through configuration, can be to avoid weight
