Wherein, the pure manual power supply module is connected with the emergency stop circuit module and the pure manual circuit module, and is used to supply power for the emergency stop circuit module and the pure manual circuit module; the manual-automatic power supply module is connected with the manual-automatic integrated circuit module for Power supply for the manual and automatic integrated circuit module; the control power supply module is connected with the pure manual button circuit module and the manual button circuit module, and is used to supply power for the pure manual button circuit module and the manual button circuit module; the backup power supply module is used for emergency Stop circuit module and pure manual circuit module supply power.

The power supply and control button power module includes emergency stop power button, emergency stop power switch KM2-1, pure manual power switch KM2-2 and manual automatic power switch KM2-3; The switch KM2-1, the pure manual power switch KM2-2 and the manual automatic power switch KM2-2 are linked; the emergency stop power button is connected with the pure manual power module; the emergency stop power switch KM2-1 is located between the pure manual power module and the Between the emergency stop circuit modules, the purely manual power switch KM2-2 is located between the purely manual power supply module and the purely manual circuit module; the manual-automatic power switch KM2-3 is located between the manual-automatic power supply module and the manual-automatic integrated circuit module between.

The power supply and control button power module also includes a manual automatic button, a manual power switch KM3-1, an automatic power switch KM3-2 and a control manual power switch KM3-3; the manual automatic button is connected to the manual power switch KM3 through a coil KM3 —1. The automatic power switch KM3-2 is linked with the control manual power switch KM3-3; the manual-automatic button is connected to the manual-automatic power module; the manual power switch KM3-1 is located between the manual-automatic power module and the manual-automatic integrated circuit module between the manual ports; the automatic power switch KM3-2 is located between the manual-automatic power supply module and the automatic port of the manual-automatic integrated circuit module; the control manual power switch KM3-3 is located between the control power supply module and the manual button circuit module between.

The power supply and control button power module also includes a backup power button, a backup power switch KM1-1 and an emergency stop pure manual power switch KM1-2, and the backup power button passes through the coil KM1 and the backup power switch KM1-1 and the emergency stop pure manual The power switch KM1-2 linkage, the standby power button is connected with the pure manual power module; The power switch KMl-2 is located between the pure manual power supply and the emergency stop circuit module and the pure manual circuit module.

For the purely manual power supply module, the standby power button is normally closed, the coil KM1 is energized, and the normally open contact KM1-2 is connected. The emergency stop power button is normally closed, the coil KM2 is energized, the normally closed contact KM2-1 is opened, and the normally open contact KM2-2 is connected. 'The voltage between the terminals is 24V, and the "pure manual +24V"' is the power supply; the voltage between the "emergency stop +24V" terminal and the "emergency stop/pure manual 0V'' terminal is 0V," Emergency stop +24V'' has no power supply. At this time, the pure manual power supply module supplies power to the pure manual circuit module, and the emergency stop circuit module does not work.

Manual/automatic circuit switching function: For the manual and automatic power supply module, since the emergency stop power button is normally closed, KM2-3 is connected. When the manual automatic button is not pressed, the button is normally open, KM3-1 is connected, and KM3-2 is disconnected. At this time, the "manual +24V" terminal is powered, and the "automatic +24V" terminal is not powered. When the manual and automatic power supply module supplies power to the manual part of the manual and automatic integrated circuit module, the automatic part does not work. When the manual and automatic button is pressed, the button is connected, the two ends of the coil KM3 are energized, KM3-1 is disconnected, KM3-2 is connected, the "automatic +24V" terminal supplies power, and the "manual +24V" terminal has no power. , at this time, the manual and automatic power supply module supplies power to the automatic part of the manual and automatic integrated circuit module, and the manual part does not work.

For the control power supply module, when the manual and automatic button is not pressed, KM3-3 is connected, the "control manual +24V" terminal supplies power, and the control power supply module supplies power to the manual button circuit module; when the manual and automatic button is pressed, KM3- 3 disconnected, the "control manual +24V" terminal has no power, and the manual button circuit module does not work. During this process, the "control pure manual +24V" terminal is always powered, and is supplying power to the pure manual button circuit module.

Emergency stop function: When there is an emergency such as gas leakage during the supersonic combustion test, press the emergency stop normally closed button, there will be no voltage at both ends of the coil KM2, the contact point KM2-1 will be connected, and KM2-2 will be disconnected from KM2-3 At this time, in the whole circuit, the "pure manual +24V'', "manual +24V'', and "automatic +24V'' terminals have no power, only the "emergency stop +24V" terminal has power. This shows that when the emergency stop button is pressed in an emergency, all control circuits do not work, and only the emergency stop circuit module continues to work.

Backup power function: In order to ensure the reliability of the power supply, and considering that the reliability of manual operation is greater than that of automatic operation, a backup power module is added to the pure manual circuit module. In this way, when the pure manual power supply module has a short circuit or a problem occurs, the coil KM1 is powered off, KM1-2 is disconnected, KM1-1 is connected, and the power supply is automatically switched to the backup power supply, so that the pure manual circuit module and the emergency stop circuit can continue The power supply of the module ensures the emergency stop or safe end of the test.

As shown in Figure 4 and Figure 5, they are schematic diagrams of the pure manual button circuit module and the pure manual circuit module, respectively. The pure manual button circuit module includes multiple pure manual control buttons T1~T24, and corresponding coils TK1~TK24. The pure manual circuit module includes multiple pure manual switch circuits, each pure manual switch circuit includes pure manual switches TK1-TK24, and the pure manual switches are used to control whether the corresponding load is working. It can be seen that the voltage between the "control pure manual +24V" terminal and the "control 0V" terminal drawn from the power supply circuit is 24V. When the pure manual control button T1 is pressed, the coil TK1 is energized. In the pure manual circuit module, if the "pure manual +24V" terminal supplies power, the corresponding contact point TK1 in the pure manual circuit module is connected, so that both ends of the load TKJ-1 are powered, and the load works normally. Here The load can be connected with an electromagnetic valve, igniter, pump starting circuit, etc. In order to detect the circuit status, the two ends of the load TKJ-1 are connected with light-emitting diodes to display the on-off status of the load TKJ-1. The load TKJ- 1. There is also a signal acquisition channel cJ-1 at both ends, which is used to send the on-off status of the load to the automatic control module. In the supersonic combustion test, 10 pure manual loads are required. Such a pure manual control circuit module is designed in total 24 channels, the extra channel can be used as a backup without load. The automatic control module also collects the power status CJ-0 of the "pure manual +24V" terminal. In order to prevent the reverse voltage formed by the electromagnetic valve in the load during power failure, a diode is added to the pure manual switch circuit.

As shown in Figures 6 to 8, they are schematic diagrams of the manual button circuit module, the manual-automatic integrated circuit module and the automatic control module, respectively. Among them, the manual button circuit module is basically the same as the pure manual button circuit module. When the manual and automatic power supply module is powered by the "manual + 24V" terminal and the manual button is pressed, the load in the manual and automatic integrated circuit module will be connected. Automatic In the control module, the coil "ZDl" of the relay is connected to the output terminal "z1" of the automatic control computer, so that the automatic control computer can send a high-level signal to energize the coil "ZDl", so that the relay in the manual-automatic integrated circuit module The normally open contact "ZDl" is closed, so that when the manual and automatic power supply module is powered by the "automatic +24V" terminal, the load can be controlled by the automatic control computer. In the automatic control computer, precise timing can be set through software, and a control high or low level signal can be sent out, so that the timing of opening and closing of each load can be precisely controlled in the supersonic combustion test. Similarly, the manual and automatic integrated circuit module is also designed with 24 channels, and each channel is connected with a light-emitting diode to display the on-off of the load, and is also connected to a signal acquisition channel for automatic control of the computer to detect the on-off of the load.

In the supersonic combustion test, the timing requirements for the control of various valves are very strict. For example, when the experiment starts to ignite, in order to avoid dangerous situations such as explosions caused by asynchronous operations, the opening time error of the hydrogen valve, oxygen valve, and igniter is required to be within 0.1 seconds. Manual operation cannot be completed in such a short time. Yes, this requires an automatic control computer that can automatically send control signals for automatic control, as shown in Figure 8. A total of 52 states on the pure manual circuit module, manual-automatic integrated circuit module and emergency stop circuit module enter the automatic control computer through the signal acquisition channel in the form of high and low levels, so that the automatic control computer can detect the power of each circuit in real time , The working condition of the load is convenient for programmed operation. For example, when the hand/automatic button is in manual mode, the automatic control computer cannot send control commands to the automatic circuit. At this time, the software can alarm, and the supersonic combustion test will not continue through the control software setting. The automatic control computer outputs control signals in the form of high and low levels, which are used to automatically control the switches of each load. The choice of automatic control computer is relatively wide, you can choose any computer including industrial computer, and then it can be realized by adding a digital I/O card that can output digital level.

As shown in Figure 9, it is an emergency stop circuit module. It can be seen that there are no switches and relay contacts in the emergency stop circuit module, and a total of 6 circuits are designed in the emergency stop circuit module. As mentioned above, when the emergency stop button is pressed, the pure manual circuit module and the manual-automatic integrated circuit module will all fail, and only the emergency stop circuit module will work. At this time, all the loads on the emergency stop circuit module will start to work. In the actual experiment, the nitrogen control valve can be connected to the emergency stop circuit module, so that when dangerous situations such as hydrogen leakage occur in the supersonic combustion test, the valves of other dangerous gases such as hydrogen and oxygen are closed, and only the nitrogen valve starts, which can quickly Clean the residual hydrogen, oxygen, etc. in the pipeline to avoid explosion. In addition, the emergency stop circuit module can also be connected to load equipment such as spray water, fire extinguishing, and alarm as required.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
