Specifically, the present invention uses a multi-core CPU as the driving core of the electro-liquid preparation system, applies thyristors as the switches of the heaters, and can achieve temperature control of the system through thyristor frequency conversion. Furthermore, since each heater is connected to a thyristor, the temperature control requirements required inside different heaters are also different during the electro-liquid preparation process. The multi-core CPU can control the working states of different thyristors according to different requirements, thereby controlling different heaters to achieve different heating temperatures, thereby improving the heating efficiency of the existing electro-liquid preparation system.

[0041] As an optional implementation, the main control module includes a first control chip and a second control chip; the first control chip and the second control chip are both CPU 226AC / DC / RLY. Figure 2 and Figure 3As shown, they are connection circuit diagrams of the first control chip and the second control chip, respectively. Wherein, the first control chip and the second control chip are both connected to the power supply module. The power supply module includes a 220V power supply unit and a 24V power supply unit, and the connection pins of the first control chip and the second control chip are both connected to the 24V power supply unit.

[0042] In addition, if Figure 2 As shown, the electro-hydraulic preparation system also includes a button switch group, which includes multiple button switches for realizing different functions; the button switch group is connected to the first control chip and the second control chip through a normally open switch, and any button switch is manually started, the normally open switch is closed, and the first control chip and the second control chip are driven to realize the corresponding functions of the button switches.

[0043] like Figure 3 As shown, the electro-hydraulic preparation system also includes an electronic switch group, which includes multiple electronic switches for realizing different functions. One end of the multiple electronic switches is connected to the switching power supply of the heater, thyristor, transmission pump and power supply, and the other end of the multiple electronic switches is connected to the first control chip and the second control chip. The first control chip and the second control chip drive the electronic switches to close or conduct to realize their corresponding functions.

[0044] Figure 2 Pins 10 to 33 of the first control chip in the circuit, and Figure 3 The 34th to 46th pins of the second control chip are connected to the button switch group; Figure 2 Pins 50 to 65 of the first control chip in the Figure 3 The electronic switch group is connected to the 48th to 49th pins and the 93rd to 99th pins of the second control chip. The first control chip and the second control chip drive the switches connected to the corresponding pins to close, thereby realizing the corresponding functions of the switches.

[0045] More specifically, in this embodiment, the system is provided with five heaters and two variable transmission pumps, namely, a first heater, a second heater, a third heater, a fourth heater and a fifth heater, a first variable transmission pump and a second variable transmission pump, each variable transmission pump and each heater are connected to the first control chip or the second control chip.

If a heater fails, the fault switch button can be manually operated to close the reserved normally open fault button connection pin, stop the system from working and perform maintenance.

[0047] Since the system includes multiple heaters, each heater is connected to multiple connection valves. In order to control the multiple connection valves accordingly, pins 20 to 33 of the first control chip and pins 40 to 46 of the second control chip are button switch connection pins for controlling the multiple connection valves. Each connection valve is connected to a button switch, and the function of opening / closing the connection valve is realized by pressing the button switch.

[0049] For example Figure 2 The 10th pin of the first control chip shown in the figure has the prefix "1# variable frequency pump start" pin, which means that the pin is the variable frequency pump start pin on the first variable frequency pump. If the prefix of a pin in the figure is "2# variable frequency pump start" pin, the pin is the variable frequency pump start pin on the second variable frequency pump. Correspondingly, if the prefix of the pin in the figure is "1# heater start" pin, the pin is the first heater start pin.

The thermal resistor transmitter can measure the temperature value of the electric liquid inside the connected heater and output the value to the main control module through a standard signal, so that the main control module can monitor the internal electric liquid temperature of the heater in real time. Among them, the number of thermal resistors connected to each thyristor is not completely the same, so they are not grouped into units.

One end of each thyristor is connected to the transmission pump module, and the other end of each thyristor is connected to the U-phase connection, the V-phase connection, and the W-phase connection. That is, each transmission pump is connected to each thyristor through three phases. More specifically, as Figure 4 The two adjacent variable transmission pumps shown are the first variable transmission pump and the second variable transmission pump from left to right. The circle corresponding to the first symbol "M" on the lower left is the water pump of the first variable transmission pump, and the frequency converter of the first variable transmission pump is connected to the water pump; the circle corresponding to the second symbol "M" on the lower left is the water pump of the second variable transmission pump, and the frequency converter of the second variable transmission pump is connected to the water pump.

[0064] Furthermore, as an optional implementation, the thyristor module also includes a thyristor connection circuit, the thyristor connection circuit includes a multi-way connecting switch, each connecting switch includes at least three circuit breakers, at least three contacts and at least three protective resistors; the thyristor connection circuit is connected to the main control module and the thermocouple extension module; the main control module controls any one of the connecting switches to close, and the thyristor receives the variable pump control signal sent by the thermocouple extension module to start working.

[0065] The thyristor protection circuit includes multiple circuit breakers, multiple contactors and multiple protection resistors; the contactor is arranged between the thyristor and the protection resistor; one end of the three contact points of the contactor is connected to the thyristor through U phase wiring, V phase wiring and W phase wiring respectively, and the other end of the three contact points of the contactor is connected to a protection resistor respectively.

After the main control module obtains the analog signal of the connected thermocouple through the EM235 module, it sends a 4-20mA variable pump control signal to the thermocouple extension module, and the first and second variable pumps of the variable pump extension module connected to it start working according to the frequency and speed given by the main control module.

[0071] More specifically, Figure 10 to Figure 14 As shown, there are respectively five thyristor wiring connection diagrams of thyristors. In order to distinguish the thyristors of this embodiment conveniently, they are named the first thyristor, the second thyristor, the third thyristor, the fourth thyristor and the fifth thyristor. Since the electro-hydraulic preparation system is provided with a button switch group and an electronic switch group, that is, the power supply of the electro-hydraulic preparation system has two methods. In each thyristor wiring diagram, the thyristor is connected to the main control module to receive the analog signal of the thermocouple sent by the main control module. Select any starting method (button / electronic switch), the electro-hydraulic preparation system is electrically started, and the thyristor receives the induced voltage signal of the thermocouple and converts it into the on or off command of the thyristor. At this time, the working state of the heater connected to the thyristor also changes accordingly.

After one end of the frequency converter receives the starting power supply, the other end is connected to a variable resistor with a given frequency converter speed. The resistance of the variable resistor is 4.7K. The variable resistor is connected to the thermocouple expansion module. By changing the resistance of the variable resistor, the pump frequency of the transmission pump can be changed and the frequency converter can be started. The value of the pump frequency is connected to the main control module through the analog output interface.
