1) hardware designs explanation
On the circuit structure by function with device layout on master control borad and two circuit boards of control and testing board, design can reduce the volume of instrument like this, and has reduced the difficulty of later period maintenance.Master control borad mainly is main control chip STM32F103VC and peripheral circuit thereof, liquid crystal interface and contrast driving circuit thereof, keystroke interface, analog voltage reference circuit, clock chip, circuit such as hummer; Control and testing board mainly is a power module, control relay circuit, AC voltage transformer, current transformer, DC voltage Hall element, current Hall sensor, and circuit such as simulating signal filtering, amplification, coefficient adjustment.
Each duty of instrument is switched by DC12V/5A band electric shock relay, and with the load of 100W power resistor simulation goat, relay provides control signal by main control chip, and triode drives the relay coil action.
Voltage transformer (VT), current transformer realize that to three-phase alternating current piezoelectric voltage, current sample voltage hall sensor, current Hall sensor are realized DC voltage, current sample are had 8 tunnel sampled signals.Sampled signal is carried out filtering via amplifier, and main control chip is delivered in processing such as amplification at last, and inner 12 ADC gather by main control chip.Be the economize on hardware cost, the voltage of three-phase alternating current, electric current real effective are realized by software, save the real effective compute chip.
Need three groups of power supplys in the total system altogether: relay power supply 12V, the digital circuit 5V that partly supplies power, mimic channel power supply ± 12V.The relay power supply is directly provided by battery, and digital circuit and mimic channel power supply are provided by WRB1205ZP-6W and WRA1215ZP-6W power module respectively.
The lcd contrast regulation voltage is set by the inner DAC of main control chip, and the high pressure that liquid crystal display inside is provided through LM358 and 78L15 is adjusted into the suitable voltage value and is input to the lcd contrast voltage input end again, with the adjustment of realization lcd contrast.This design than in the past more conventional thinking practiced thrift hardware cost greatly, given full play to the internal resource of main control chip.
Button is directly driven by main control chip I/O mouth.
Clock is provided by the DS1302 clock chip.
2) program design explanation
Program is mainly accomplished functions such as LCD Controller, button input response, relay control, electric current and voltage collection.
Page display operation is following:
Press the power key start, start at first gets into information page, and is general 4 seconds of duration, as shown in Figure 3.Under this page, push button and do not have response.
Get into the goat type selecting page then, as shown in Figure 4.Under this page, press "<<" key reduction lcd contrast, press ">>" key increase lcd contrast, press the unlatching of " backlight " key or close LCD backlight, press " menu " key and get into goat model choice menus, as shown in Figure 5.There is not response by other keys.
Under Fig. 5 page, press "<<" key or ">>" the goat model that the key selection needs, get back to Fig. 4 page by " cancellation " key, by " confirming " key entering initialization page shown in Figure 6, the approximately lasting 2S of the initialization page.
Get into after the initialization and measure the page.S700K, ZD (J) 9 types get into the measurement page shown in Figure 7, ZD6-E (1), ZD6-J (2), ZD6-E (3), four-wire system, ZD6-J (4) type gets into Fig. 8 and measures the page.
Press " confirming " key under the page and get into operating state (fixed behaviour or anti-behaviour) measuring, detection action circuit fault whether as if the phase order of 3-phase AC mistake, then shows in the duty: wiring error under operating state; If the three-phase alternating current phase shortage shows: phase shortage.Press " cancellation " key tenth skill under the operating state, get into expression state (location or antiposition).If alternating current is higher than 300V, direct current is higher than 160V to the expression state down, and duty shows: action circuit wiring error.
Under the expression state, press " menu " key and get into the menu setting page, as shown in Figure 9.
Continuously by " Menu key " key, cursor is selected in working order with in the Time of Day by turns under the menu setting page.By "<<" or ">>" key duty or Time of Day are provided with.Preserve setting by " confirming " key, withdraw from setting, and the page is measured in entering by " cancellation " key.
By "<<" or ">>" key lcd contrast is set down measuring the page, by the unlatching of " backlight " key or close LCD backlight.
The alternating current real effective calculates:
The discretize computing method of alternating current real effective are to block complete cycle, and the sampled point side of carrying out is calculated with root in the multicycle.Take all factors into consideration the operating rate of precision and main control chip, with sampling 40 points in the 50Hz alternating current monocycle, three cycles are carried out first power and root computing in the design, and calculated value meets accuracy requirement fully.Simultaneously the real effective after calculating is averaged value filtering, make data stable more and accurate.
Because the parameter that needs AD to gather is many, and three-phase alternating current piezoelectric voltage 5 tunnel is arranged, electric current 3 tunnel, dc voltage 2 tunnel, electric current 1 tunnel, cell voltage 1 tunnel, totally 12 the tunnel, the DMA technology of STM32 processor is adopted in the ADC conversion, improves the operational efficiency of program greatly.
