Embodiment 1
[0032] according to( figure 2 ), the VIT control system is composed of the main control module 1, the current encoding module 2, the voltage encoding module 3, the current decoding module 4, and the voltage decoding module 5.
[0033] The working process and principle of the system are as follows:
[0034] 1. Main control module 1
[0035] The main control module 1 is the core of the whole system. It not only has the function of logic operation, but also sends the time reference signal with synchronization signal of the whole system to the signal line to ensure that the whole system works on a unified time reference. The time reference waveform is ( image 3 ):
[0036] The working process of main control module 1 is as follows (see Figure 4 ):
[0037] The main control module 1 is composed of a logical operation unit, a signal extraction and classification unit, a time signal extraction unit, a voltage signal decoding unit, a current signal decoding unit, a voltage cod...
Embodiment 2
[0054] According to the composition of the above system, the main control module of the system such as ( Figure 13 ), which mainly consists of the following parts:
[0055] 1. Logic operation unit mainly composed of single-chip microcomputer;
[0056] 2. A 3×3 matrix group composed of 9 three-terminal input AND gates from 1 to 9;
[0057] 3. The current and voltage encoding unit composed of the resistor row R3 and the transistors V1~V4 behind it;
[0058] 4. A voltage decoding unit composed of voltage comparator 1, latch 1, and three AND gates 10, 11, and 12;
[0059] 5. Voltage comparator 2, latch 2, six AND gates 13~18, and a current decoding unit composed of transistors V6, V7, and V8.
[0060] When the system is powered on, the logic operation unit sends a synchronous pulse and a time reference pulse, respectively controls the base of the transistor V4 through R1 and R2, and sends the synchronous signal and the time base pulse to the signal line through V4. After rece...
