Specifically, when the invention needs to be started, a high-power direct-current constant-voltage constant-current power supply of the constant-volume combustion bomb integrated monitoring controller needs to be firstly connected, and in the embodiment, the high-power direct-current constant-voltage constant-current power supply is provided with a main power supply switch, and the main power supply switch is respectively provided with a 380V alternating-current switch, a 220V alternating-current switch, a 24V alternating-current switch and an indicator lamp. When the constant volume combustion bomb is required to be heated, only a heating switch of the heating controller is required to be turned on, the environmental temperature in the constant volume combustion bomb is changed through an electric heating wire with rated power of 12KW, after the upper computer sets the temperature, the constant volume combustion bomb integrated monitoring controller continuously transmits signals to an electric heating wire transformer of the electric heating unit, and the voltage of the electric heating wire is changed; at this time, the parameter data display can display the temperature indication in the constant volume combustion bomb measured by the temperature sensor, and the temperature data can be simultaneously transmitted to the upper computer, and if the upper computer judges that the temperature in the constant volume combustion bomb is abnormal, the upper computer can warn and remind, and at this time, an operator can press an emergency stop button or reduce the voltage in the upper computer to slow down the electrifying of the thermocouple on the constant volume combustion bomb.
Referring to fig. 4, when the pressure in the cavity of the constant volume combustion bomb is required, if only a spraying experiment is required, the air inlet valve of the nitrogen air inlet and outlet switch is opened, at this time, the opening signal of the constant volume combustion bomb integrated monitoring controller is transmitted to the electromagnetic valve switches (1)/(2) and (4) in the gas storage device, the nitrogen in the nitrogen cylinder enters the constant volume combustion bomb, and the pressure sensor on the constant volume combustion bomb continuously monitors the environmental pressure in the constant volume combustion bomb. If the electromagnetic valve needs to do a combustion experiment, an air inlet valve of an air inlet and outlet switch is opened, at the moment, signals of a monitoring control system are transmitted to electromagnetic valve switches (3) and (4) in the gas storage device, air in the air bottle enters the constant volume bomb, a pressure sensor on the constant volume bomb continuously monitors the internal environment pressure of the constant volume bomb, and the internal environment pressure value of the constant volume bomb is displayed on a parameter data display; if the air inlet pressure is not reduced enough to continue to charge before reaching the set threshold value of the background pressure in the constant volume bomb, the air compressor switch can be pressed to pressurize the air, the parameter data display can display the air pressure indication in the constant volume burning bomb, the pressure data in the constant volume bomb can be simultaneously transmitted to the upper computer, and if the upper computer judges that the pressure in the constant volume burning bomb is higher than the set pressure, the upper computer automatically stops the air inlet into the constant volume bomb, namely, closes the electromagnetic valve switch of the air bottle; when the pressurization of the given volume combustion bomb is finished, the exhaust is carried out according to an exhaust switch, at the moment, signals of the monitoring control system are transmitted to an electromagnetic valve switch in the gas storage device, wherein the electromagnetic valve switches (1), (2) and (3) are closed, and the electromagnetic valve switch (4) is opened to discharge waste gas into the atmosphere; meanwhile, the constant volume combustion bomb integrated monitoring controller continuously monitors the air pressure in the constant volume combustion bomb, and the exhaust is automatically stopped when the air pressure reaches a set threshold value or can be manually stopped by an operator. When the condition in the constant volume combustion bomb needs to be checked, the LED light source is only required to be turned on by pressing, and the LED light source illuminates the condition in the constant volume bomb through the window, so that an operator can observe the condition in the constant volume bomb conveniently. When fuel is required to be injected into the constant volume combustion bomb, the oil temperature adjusting switch can be pressed to adjust the oil temperature, the oil pump fan switch can be pressed to adjust the oil pressure, and the oil pump parameter can be adjusted on the oil pump controller.
When the constant volume combustion bomb is required to be filled with fuel gas, only the fuel gas pressurizing switch on the fuel gas pressurizing controller is required to be pressed, and the fuel gas pressurizing has certain danger, so that the number of the fuel gas pressure display screen is required to be observed in the process of fuel gas pressurizing, and meanwhile, an alarm can be generated in the upper computer, so that an operator can press the fuel gas to be cut off in emergency at abnormal time conveniently. The high-power direct-current constant-voltage constant-current power supply is equipment for controlling the oil injection parameters of the oil injector. When the oil is sprayed, in order to prevent the oil sprayer from being influenced by high-temperature gas in the constant-volume combustion bomb, a cooling system switch can be pressed to cool the oil sprayer at the moment, so that the oil sprayer runs stably, and experimental precision is not influenced.
As shown in FIG. 5, the electrical coordination process related to the whole system mainly gives a control signal to the upper computer, and starts the corresponding module, and at the moment, the indicator lights on the corresponding module receive the upper computer signal and start to give light. Meanwhile, signals are transmitted to a singlechip and a controller under the module through corresponding pins, and equipment with requirements is opened through related electric control valves, electric control switches and the like. The corresponding relevant parameters on the equipment are transmitted to a data display and an upper computer under the corresponding module through a data line after being measured by a sensor. After the upper computer sets given parameters, the corresponding parameter data returned by the sensor is adjusted to a certain extent for the electric control valve and the electric switch, so that the data received by each parameter data display and the upper computer are changed in real time, and the adjustment is stopped when the corresponding parameters reach a certain range of the set parameters, thereby realizing feedback adjustment and finally realizing the corresponding parameter change. In the same way, the whole system adopts a manual speed regulating button and an emergency stop button so as to ensure that the system can process when in fault and further protect equipment. The electric appliance cooperation in the process mainly relates to the control of the emergency stop button on the electric control valve, the electric control switch and the corresponding indicator lamp, namely, signals are given after the emergency stop button is pressed, the electric control valve and the electric control switch are closed, and meanwhile, the corresponding indicator lamp is closed. After the speed regulating button is manually rotated, the size of the passing current in the corresponding circuit is changed, so that the opening degree of the electric control valve and the electric control switch is controlled, and the change and adjustment of parameters under the corresponding module are ensured.
