Preferably, described CPU module adopts double looper to be connected with analogue collection module with comprehensive module.
In sum, the utility model advantage: 1, each circuit links to each other with modular form, and is connected and fixed by double looper, and each module can be worked alone on hardware platform, has improved stability and the ease for use of whole hardware platform.2, adopted the TFT LCD, made operation interface more clear, and can carry out the touch screen operation, reduced the quantity of mechanical key, made the function of hardware platform access expansion.3, adopt 32 arm processor, increased the arithmetic speed of hardware platform.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
The utility model provides a kind of power quality analysis hardware platform, as shown in Figure 1, the analogue collection module that comprises the CPU module and link to each other with the CPU module and comprehensive module, the CPU module comprises CPU and the clock circuit that is connected with CPU respectively, storer and man-machine interface circuit, and the man-machine interface circuit comprises TFT LCD and mechanical key circuit; Described comprehensive module comprises power module, communication module, the amount of opening the light detection module and the output control module that is connected with CPU respectively; Described analogue collection module is connected with pulse output module.
When the power quality analyzer hardware platform was in running order, power module provided power supply for the power quality analyzer hardware platform.The switching value detection module has strengthened the antijamming capability of electromagnetic field to external world strong under the insulation blocking of photoisolator.The switching value detection module is transferred to CPU with the data monitored signal, and the signal that process CPU handles is sent on the TFT LCD and shows.Analogue collection module is gathered current and voltage signals, CPU regularly read the signal of analogue collection module by clock circuit and will handle after signal send on the TFT LCD and show.CPU is connected with output control module with storer simultaneously, and CPU reads the parameter of storer, with the signal contrast of analogue collection module collection.The signal of gathering when analogue collection module is in the alarm parameters scope time, and CPU sends signal to output control module, drives warning device and gives the alarm.
The man-machine interface circuit comprises TFT LCD and mechanical key circuit, and the TFT LCD comprises 3.5 inches touch-screen.Compare with traditional industrial LCD, the TFT LCD can make operating personnel arrange by the parameter of touch-screen to the power quality analyzer hardware platform, and can switch in the signal that shows on the display.By touching control, reduced the quantity of mechanical key, make the power quality analyzer hardware platform can increase more function, and be convenient to operation.
Mechanizing circuit is used for startup/closing control hardware platform.The user can realize man-machine conversation easily by the man-machine interface circuit, also can carry out exchanges data and straighforward operation by communication module simultaneously.CPU sends the signal that receives to communication module, and communication module transfers signals to the office terminal, makes the user carry out remote monitoring to hardware platform.
Analogue collection module is connected with pulse output module, and analogue collection module is transferred to pulse output module with voltage, the current signal that collects, and according to the useful power that P=UI calculates electric energy, electrical energy pulse is exported controlled then.
Further, more accurate for the signal that analogue collection module is gathered, adopt the A/D metering module to carry out signals collecting.
Further, select arm processor as CPU.
Further, strengthen in order to make the steadiness between the module, improve the stability of hardware platform and be convenient to maintenance, the CPU module is with analogue collection module and comprehensively adopt double looper to be connected between the module.
Though by reference to the accompanying drawings embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
