The concrete principle of above-mentioned functions is as follows：
Heating system automatic heating Force balance control device can gather DC electric current and the original of voltage signal by AI acquisition interfaces
Reason：AI acquisition interfaces have 3 binding posts, when needing access current signal, it is necessary to which short circuit two of which binding post, is remained
1 remaining binding post connects the negative pole of signal, when needing access voltage signal, it is only necessary to access 2 binding posts, thus
Realize can either collection voltages signal, the function of current signal can be gathered again.
Heating system automatic heating Force balance control device exports DC0-20mA or DC0-10V voltage signals by AO output interfaces
Principle：Electric current and voltage output share the volume AO output signals of CPU outputs, so when needing output DC electric current signal, 2 tunnels
AO interfaces share positive pole, when needing output dc voltage signal, it is necessary to by the current interface short circuit of correspondence sequence channel, realize not
The analog output of same specification.
Heating system automatic heating Force balance control device DI interface acquisition principles：4 road DI interfaces have public negative terminal, typically need
Access digital quantity low level signal.4 road DO interfaces provide dry contact interfaces, can as the switch port in a loop,
Both DC24V/5A signals can be accessed, AC250V/5A signals can be also accessed.
The LED state instruction principle of heating system automatic heating Force balance control device：When controller normal operation, control
Device running status lamp Chang Liang, otherwise running status lamp flicker.4 road DI acquisition interfaces and 4 road DO output interfaces have 1 LED respectively
Lamp carries out state instruction, and when DI acquisition states are 1, on the contrary corresponding LED is bright, then go out, when DO output states are 1, correspondingly
LED it is bright, it is on the contrary then go out.
The automatic detection short trouble and overload protection failure of the MBUS interfaces of heating system automatic heating Force balance control device
Principle：In an idle state, the current value passed through is approximately less than equal to 1.5mA MBUS slave units, and multiple MBUS slave units parallel connections are even
It is connected in MBUS buses, slave unit number and idle current value in MBUS buses are proportional, CPU cycle detection MBUS is total
The current value of idle condition on line, if current value is equal to 0mA or so, now MBUS buses are zero load, if current value is much larger than
Number theoretical maximum current value is loaded, then MBUS buses are short-circuit condition.If current value and maximum load corresponding current value difference value
For 1.5mA integral multiple, then now MBUS buses are overload.
Heating system automatic heating Force balance control device carries out parameter configuration and operational factor by LCD touch screen to controller
Displaying principle：Controller develops various UI interfaces for LCD touch screen, respectively configures UI interfaces and parameter shows UI circle
Face, the switching at various UI interfaces is realized by the touch function of LCD touch screen, when needing configuration parameter, is switched to configuration UI
Interface, now the touch function of touch-screen be similar to computer mouse function, pass through the button prompts at UI interfaces, you can easily
Realize after the completion of parameter configuration, parameter configuration, selection preserves function, realize the preservation to parameter.Shown when needing operational factor
When, it is only necessary to LCD screen is switched to operational factor and shows UI interfaces, you can starts controller operation, display operation is periodically flushed
Parameter.
