[0042] The exemplary embodiments of the present application will be described in more detail below in conjunction with the accompanying drawings in the embodiments of the present application. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to enable the scope of the present application to be fully conveyed to those skilled in the art.

[0043] Electric steamer is an indispensable equipment for ensuring catering quality in field seismic data collection projects. When using traditional electric steamer, refer to Figure 1 , Figure 1 This is a circuit diagram of an electric steamer provided by the relevant technology. When the QC contactor is closed and the electric steamer starts to heat, the electric heating tube of the electric steamer runs at 100% power. Generally, when the water in the electric steamer is heated to 100°C, steam will be generated in the steamer. When the pressure in the steamer is greater than the external atmospheric pressure, a large amount of steam will continue to leak out (the steamer body is equivalent to a normal pressure "boiler", and the door of the electric steamer leaks due to design reasons). This leakage phenomenon will continue until the steamer is finished. This part of energy will be discharged into the atmosphere, which is also the root cause of the waste of electricity in traditional electric steamers. The electric heater is heated at full power throughout the heating process, and a large amount of steam leaks due to pressure. The leakage of steam not only increases the steaming time, but also causes a large amount of electricity waste. At the same time, there are also safety and health risks.

[0044] In view of this, in order to solve the above problems, the present embodiment provides a control system for an electric steamer, which detects the temperature and pressure in the steamer through a detection module during the heating process of the steamer, and when the temperature exceeds a preset temperature and / or the pressure exceeds a preset pressure, switches the second power supply circuit with a lower output voltage to power the heater, thereby maintaining the temperature in the steamer at 100°C and ensuring that the steam pressure in the steamer remains at a certain pressure value, thereby avoiding the electric steamer from running at high power consumption for a long time, causing excessive waste of electricity, and solving the above problems.

[0045] Reference Figure 2 , Figure 2 is a schematic diagram of a control system provided in an embodiment of the present application, from Figure 2 It can be seen that the control system includes: a power supply, a heater, a first power supply circuit, a second power supply circuit, a detection module and a control module, wherein the connection relationship between the power supply, the heater, the first power supply circuit, the second power supply circuit, the detection module and the control module is:

[0046] The first power supply circuit and the second power supply circuit are connected in parallel between the power supply and the heater. The detection module is located in the steamer and connected to the detection control module. The control module is connected to the first power supply circuit and the second power supply circuit, and a voltage regulating module is provided on the second power supply circuit.

[0047] The heater, detection module and control module are configured to have the following functions:

[0048] The heater is configured to heat the steamer in the electric steamer vehicle; the detection module is configured to detect the temperature and pressure in the steamer during the heating process of the steamer, and output a voltage regulation signal to the control module when the temperature exceeds a preset temperature and / or the pressure exceeds a preset pressure; the control module is configured to control the first power supply circuit to be turned on in response to the heating signal; and, in response to the voltage regulation signal, disconnect the first power supply circuit and turn on the second power supply circuit; the voltage regulation module is configured to step down the voltage output by the power supply to output the stepped-down voltage to the heater.

[0049] In this embodiment, the power supply is a three-phase AC power supply, and the heater can be a resistor. When the control system is used to control the heater to heat the steam box of the electric steamer, a heating signal is first sent to the control module. The control module responds to the heating signal and controls the first power supply circuit to be turned on. Then the power supply outputs a voltage to the heater through the first power supply circuit. At this time, the heater operates at full power, so that the temperature in the steam box quickly reaches the preset temperature. During the process of the heater heating the steam box, the detection module detects the temperature and pressure in the steam box in real time. Generally, the higher the temperature, the greater the pressure. When the temperature reaches 100°C, the water in the steam box will produce steam. Even if it is still operated at full power, the temperature of the water in the steam box is still 100°C, and the temperature will not rise again, but a large amount of steam will be generated. When the pressure in the steam box is greater than the external atmospheric pressure, a large amount of steam will continue to leak out, causing excessive energy waste and also prolonging the working time of the electric steamer. Therefore, when any of the conditions that the temperature in the steam box exceeds the preset temperature and the pressure in the steam box exceeds the preset pressure is met, the detection module will output a voltage regulation signal to the control module. The voltage regulation signal can be a mechanical action or an electrical signal. In this embodiment, the control module may be a PLC (Programmable Logic Controller), the detection module may be a detection circuit composed of a temperature sensor and a pressure sensor, and the voltage regulating module may be a circuit that directly steps down the voltage output by the power supply according to a preset voltage.

Since the second power supply circuit is provided with a voltage regulation module, the voltage regulation module is configured to step down the voltage output by the power supply and output the stepped-down voltage to the heater, so that the heater can maintain the current temperature of the steamer while reducing the electric energy consumed by the heater, thereby achieving the purpose of energy saving.

After receiving the voltage regulating signal, the control module can also control the voltage regulating module to adjust the voltage output by the power supply to the target voltage so that the second power supply circuit outputs the target voltage to the heater. The target voltage can be set according to the performance of the heater and the actual situation in the steamer, and this embodiment does not limit it.

[0056] In this embodiment, the control system also includes a circuit breaker, and the input end of the circuit breaker is connected to the power supply, and the output end of the circuit breaker is respectively connected to the first power supply circuit and the second power supply circuit. When the current output by the power supply exceeds the preset current, the circuit breaker can be directly disconnected to switch the connection between the first power supply circuit and the second power supply circuit and the power supply to protect the safety of various electronic components on the control system. The preset current can be the maximum current that the control system can withstand, or the safe current for normal operation of various electronic components on the control system.

[0058] In this embodiment, the detection module includes a sampling unit and a generating unit. The sampling unit can collect the temperature and pressure of the steamer during the heating process in real time, and determine whether the current temperature in the steamer exceeds the preset temperature, or whether the current pressure in the steamer exceeds the preset pressure. When the temperature exceeds the preset temperature, or the pressure exceeds the preset pressure, the output temperature signal is output to the generating unit, or the output pressure signal is output to the generating unit. After receiving the temperature signal or the pressure signal, the generating unit determines that the current temperature in the steamer exceeds the preset temperature, or the current pressure in the steamer exceeds the preset pressure, and the generating unit generates a pressure regulating signal and outputs the pressure regulating signal to the control module.

[0059] In a specific embodiment, the collection unit includes a temperature sensor and a pressure sensor; the temperature sensor is arranged on the side wall of the steamer, and is configured to detect the temperature inside the steamer in real time, and output a temperature signal to the generation unit when the temperature exceeds a preset temperature; the pressure sensor is arranged at the steam hole of the steamer, and is configured to detect the pressure inside the steamer in real time, and output a pressure signal to the generation unit when the pressure exceeds a preset pressure.

[0060] In this embodiment, the collection unit includes a temperature sensor and a pressure sensor. The temperature sensor is arranged on the side wall of the steamer to detect the temperature inside the steamer in real time, and outputs a temperature signal to the generation unit when the temperature exceeds a preset temperature. The pressure sensor is arranged at the steam hole of the steamer to collect the pressure at the steam hole and detect the pressure inside the steamer in real time, and outputs a pressure signal to the generation unit when the pressure exceeds a preset pressure.

[0061] In a specific embodiment, referring to Figure 3The control system further includes: a human-machine module; wherein the human-machine module is connected to the control module; the human-machine module is configured to output a heating signal to the control module in response to a mechanical start instruction or a wireless start instruction.

[0062] In this embodiment, the control system also includes a human-machine module, which is connected to the control module. When the operator needs to start the electric steamer, he can press the mechanical button on the human-machine module, and the human-machine module will receive the mechanical start instruction and output a heating signal to the control module.

[0063] Alternatively, the operator can remotely send a wireless start command to the human-machine module through an electronic device. At this time, the human-machine module receives the wireless start command and can also output a heating signal to the control module. Starting the electric steam car in two ways is more convenient for the operator. Secondly, if the voltage output by the power supply in the control system is 220V, remote contactless starting of the electric steam car can better ensure the personal safety of the operator.

[0064] In a specific embodiment, referring to Figure 3 A first signal light is provided on the first power supply circuit, and a second signal light is provided on the second power supply circuit; the first signal light is configured to light up when the first power supply circuit is turned on; the second signal light is configured to light up when the second power supply circuit is turned on.

[0065] In this embodiment, in order to facilitate the operator to know whether the first power supply circuit is connected to the second power supply circuit, and whether the first power supply circuit originally outputs the voltage for the heater and has now smoothly switched to the second power supply circuit as the heater output voltage, a first signal light is provided on the first power supply circuit, and a second signal light is provided on the second power supply circuit.

[0067] In this embodiment, since the heater heats the steamer, specifically, the heater heats the water so that the heated water heats the steamer, when the water is heated to 100°C, steam will be generated, and the water level in the steamer will be reduced. If the water in the steamer is evaporated, the heater will directly heat the steamer or other equipment of the electric steamer, which is easy to burn the steamer, and is more likely to burn other equipment. In order to ensure the safety of the electric steamer and the steamer, the control system also includes a fault indicator light, which is connected to the detection module. The detection module can detect the water level in the steamer during the steamer heating process. If the water level reaches the preset water level, the fault indicator light will be lit to remind the operator. In addition, the detection module can also detect that there is no water in the steamer, and output a power-off signal to the control module. In response to the power-off signal, the control module cuts off the power supply circuit of the current heater output voltage to avoid continuous heating of the heater, resulting in damage to the electric steamer or the steamer, protecting the heater and the box from high temperature damage, and improving the service life of the heater.

[0068] For example, the following will be Figure 1-Figure 6 , the control system provided in this embodiment is further described in the application of an electric steam car:

[0070] When the electric steam car is started, KM3 is first controlled to close, and the electric steam car runs at 24KW, i.e. 100% full power. When the electric heating tube is heated for 15 minutes, if it is detected that the temperature inside the electric steam car reaches 100°C and the pressure reaches a certain pressure value, the control module controls KM1 and KM2 to close at the same time, KM3 is disconnected, and the voltage regulating module is connected to the main circuit for intelligent power adjustment to ensure that the electric steam car achieves the best energy-saving efficiency.

[0071] Reference Figure 5 , Figure 5 is a control logic diagram of a control system provided by an embodiment of the present application; Figure 5 It can be seen that Figure 5 It is connected with power indication, fault indication, manual operation indication, automatic operation indication, etc., and can also complete other interlocking functions. Figure 5The power supply line switch adopts a highly sensitive leakage protector to improve the protection of personnel from electric shock. The original operation buttons and switches are AC 220V / 380V system, and the operating voltage is DC 24V, which protects the safety of operators.

[0072] Refer to the following Figure 6 right Figure 1 and Figure 4 The control systems of the corresponding electric vehicles are compared to explain the heating of the whole box:

[0073] During the use of the electric steamer, the electricity price is: 0.8 yuan / kw.h, the number of electric steamers is 4, and the construction period is 100 days.

[0074] Figure 1 Electricity consumption of electric steamer: 24kw×4 units×6h / day×100 days=57kw.h; electricity fee: 0.8 yuan / kw.h×57=46080 yuan;

[0075] Figure 4 Electricity consumption of electric steamer: (24×1 / 4+24×0.2×3 / 4)kw×6h / day×100 days×4 units=23040kw.h; electricity price is 0.8 yuan×23040=18432 yuan;

[0076] The electricity cost can be saved: 46080-18432=27648 yuan

[0077] Summary: A total of 27648 yuan can be saved, and the electricity saving rate is 60%. The electric steam car of this embodiment has a better energy-saving effect. Secondly, the application of the electric steam car of this embodiment improves safety and reduces the labor intensity of operators.

Combined with the above description, it can be seen that: Figure 1 The electric steam car always runs at 100% constant power. Figure 4 The heater of the electric steamer runs at full power for 15 minutes (1 / 4 hour). At this time, the steam temperature in the steamer reaches 100°C and is maintained at a certain pressure value. At this time, the heating power of the heater is reduced to 4.8KW (20%) to maintain the temperature in the steamer at 100°C. At the same time, the steam pressure in the steamer is kept at a certain pressure value to avoid leakage due to excessive pressure until the heating process is completed.
