[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Controllable vibration sources that use constant speed control for excitation maintain the fuel engine at a constant speed, whether in the excitation or driving state. Due to the large tonnage of the controllable vibration source, the fuel consumption to maintain the constant speed is large, resulting in a high fuel cost for the controllable vibration source in the field operation cost. Therefore, effectively reducing the fuel consumption of the controllable vibration source and improving fuel utilization efficiency is of great significance for reducing operating costs and achieving energy conservation and emission reduction.

[0040] In the exploration and excitation process of a controllable seismic source, the operating states of the controllable seismic source include excitation states such as preparing for excitation and in the process of excitation, as well as non-excitation states such as preparing to drive and driving. For a controllable seismic source, although the excitation state occupies a relatively large proportion of the time and needs to maintain a constant speed, when the controllable seismic source is in the non-excitation state, the high constant speed will cause the fuel engine to have power surplus, resulting in high fuel consumption and high operating costs. Therefore, this embodiment provides a fuel control system for a fuel engine based on a controllable seismic source. During the production operation, when the controllable seismic source is in the excitation state, the fuel engine speed is controlled at a high constant speed, while when the controllable seismic source is in the non-excitation state, such as when driving, the fuel engine speed is controlled to decrease accordingly. In this way, intelligent adaptive control can be performed while ensuring the vibration output and transfer efficiency of the controllable seismic source, thereby reducing the fuel consumption of the fuel engine, thereby reducing operating costs, saving energy and reducing emissions, promoting green development, and extending the service life of the fuel engine.

[0041] See Figure 1 This utility model embodiment provides a fuel control system for a fuel engine based on a controllable vibration source. The fuel control system may include: a controllable vibration source 101, a weight sensor 102, a fuel engine 103, and a computing chip 104.

[0042] The weight sensor 102 is installed on the lower chamber of the lifting cylinder of the controllable vibration source 101, and the fuel engine 103 is connected to the controllable vibration source 101.

[0043] The computing chip 104 is connected to the weight sensor 102 and the fuel engine 103 respectively;

[0044] The weight sensor 102 collects the weight sensing signal on the lower chamber of the lifting cylinder and transmits it to the computing chip 104.

[0045] The computing chip 104 analyzes the received pressure sensing signal, obtains the pressure, and after the pressure exceeds the preset pressure threshold, determines that the vibration state of the controllable vibration source 101 is a non-excitation state. It then outputs an engine speed reduction signal to the fuel engine 103 so that the fuel engine 103 adjusts the current speed to a preset low speed according to the engine speed reduction signal.

[0046] In this embodiment, as an optional embodiment, the weight sensor is connected to the computing chip via a first controller area network (CAN) bus, and the fuel engine is connected to the computing chip via a second controller area network bus.

[0047] In this embodiment, as an optional embodiment, the weight sensor is installed on the lower cavity of the lifting cylinder by adhesive bonding.

[0048] In this embodiment, a pressure sensor deployed on the lower chamber of the lifting cylinder of the controllable vibration source collects pressure sensing signals on the vibration source plate driven by the lower chamber of the lifting cylinder. The signals are transmitted to the computing chip via the Controller Area Network (CAN) bus. The computing chip analyzes the received pressure sensing signals to obtain the pressure. If the pressure is determined to be less than a preset pressure threshold, it indicates that the vibration source plate is in a critical contact state or a non-contact state with the ground, meaning the controllable vibration source is in an unexcited state. At this time, fuel consumption can be reduced by decreasing the speed of the fuel engine. Thus, by outputting a signal to reduce the engine speed to the fuel engine, the speed of the fuel engine is reduced, thereby reducing the fuel consumption of the fuel engine.

[0049] In this embodiment, as an optional embodiment, the fuel control system further includes:

[0050] The state memory 105 is connected to the arithmetic chip 104 and stores the vibration state of the controllable vibration source 101 determined by the arithmetic chip 104.

[0051] In this embodiment, after the computing chip determines that the vibration state of the controllable source is in a non-excitation state, if the stored controllable source state is in a stable excitation state, then the stored controllable source state is updated to an unstable excitation state.

[0052] In this embodiment, as another optional embodiment, the fuel control system further includes: a drive motor 106 and a load sensor 107, wherein,

[0053] The load sensor 107 is mounted on the drive motor 106, and the drive motor 106 is connected to the fuel engine 103.

[0054] The computing chip 104 is also connected to the load sensor 107 and the drive motor 106 respectively;

[0055] When the controllable vibration source 101 is in a non-excitation state, the load sensor 107 collects the load sensing signal on the drive motor 106 used to drive the fuel engine 103 and transmits it to the computing chip 104.

[0056] The computing chip 104 analyzes the received load sensing signal, obtains the hydraulic pressure value, and determines that the vibration state of the controllable vibration source 101 is an unstable excitation state. When the hydraulic pressure value is less than the preset load threshold, it outputs a motor displacement increase signal to the drive motor 106 so that the drive motor 106 adjusts the current displacement of the driving fuel engine 103 to the preset output displacement according to the motor displacement increase signal.

[0057] In this embodiment, the load sensor collects the hydraulic pressure value information of the drive motor output displacement to the fuel engine, encapsulates it into a load sensing signal, and the computing chip analyzes the load sensing signal to obtain the hydraulic pressure value. When the hydraulic pressure value is less than the preset load threshold, the drive displacement output by the drive motor to the fuel engine is increased.

[0058] In this embodiment, as an optional embodiment, the engine speed reduction signal is a current signal, and different magnitudes of current in the current signal represent different speeds.

[0059] In this embodiment, as an optional embodiment, the fuel engine includes a fuel injector, which adjusts the amount of fuel injected into the fuel engine based on a received engine speed reduction signal.

[0060] In this embodiment, as an optional implementation, the motor displacement adjustment signal is a current signal, where different current magnitudes represent different displacements. The drive motor includes an electromagnetic regulating valve, a valve core, a linkage mechanism, and a swashplate.

[0061] The electromagnetic regulating valve drives the valve core to move according to the received motor displacement increase signal. The valve core pushes the linkage mechanism to move, and the linkage mechanism pushes the swashplate.

[0062] In this embodiment, the output displacement of the motor is adjusted by driving the valve core to move the linkage mechanism to push the swashplate.

[0063] In this embodiment, as an optional embodiment, the computing chip includes: a pressure sensing signal interface, a speed signal interface, a load sensing signal interface, a displacement signal interface, and a computing unit, wherein...

[0064] The weight sensing signal interface is connected to the weight sensor and the processing unit respectively;

[0065] The speed signal interface is connected to both the fuel engine and the processing unit.

[0066] The load sensing signal interface is connected to the load sensor and the processing unit, respectively;

[0067] The displacement signal interface is connected to the fuel engine and the computing unit respectively.

[0068] In this embodiment, as an optional embodiment, the operating system of the fuel control system is an open-source system based on UNIX.

[0069] In this embodiment, as an optional implementation, a first speed (high speed) of the fuel engine corresponding to the excitation state and a second speed (low speed) of the fuel engine corresponding to the non-excitation state are set. During the operation of the controllable vibration source, the speed of the fuel engine switches between the first speed and the second speed. The first speed is greater than the second speed. That is, when the sensed pressure of the flat plate reaches a preset pressure threshold, the speed of the fuel engine is switched to the first speed, for example, 1800 rpm. When the sensed pressure of the flat plate is lower than the pressure threshold, the speed of the fuel engine is switched to the second speed, for example, 1600 rpm.

[0070] In this embodiment, as an optional embodiment, by utilizing the correspondence between the torque, speed and fuel consumption performance of the fuel engine, and by adaptively controlling and adjusting the displacement of the drive motor and the engine speed, it is possible to reduce the fuel consumption of the fuel engine while ensuring the controllable vibration output and shifting efficiency under the original same gear driving conditions.

[0071] In this embodiment, as another optional embodiment, the fuel control system further includes:

[0072] The trigger (not shown in the figure) is connected to the computing chip and the load sensor respectively. After receiving the engine speed reduction signal output by the computing chip, it sends a start acquisition signal to the load sensor.

[0073] In this embodiment, the power consumption of the load sensor can be effectively reduced by controlling the timing of its data acquisition.

[0074] In this embodiment, as another optional embodiment, the fuel control system further includes:

[0075] The shut-off device is connected to both the computing chip and the load sensor. After receiving the engine speed increase signal output by the computing chip, it sends a stop acquisition signal to the load sensor.

[0076] Figure 2 This is a schematic diagram illustrating the relationship between engine speed and torque in a fuel control method with a controllable vibration source provided in an embodiment of the present invention. Figure 2 As shown, in this embodiment, the unit of torque is foot-pound-force (ft-lbf). The corresponding torque can be obtained by obtaining the engine speed of the fuel engine.

[0077] Figure 3 This is a schematic diagram of the relationship curve between the speed and power of a fuel engine in a fuel control method for a controllable vibration source provided in an embodiment of the present invention. In this embodiment, as an optional embodiment, if the hydraulic pressure value is less than a preset load threshold, the relationship curve between the speed and torque of the fuel engine is queried from a pre-stored graph, and the rated torque corresponding to the low speed threshold is obtained. The load threshold is equal to the rated torque. If the torque corresponding to the hydraulic pressure value is less than the rated torque, the drive displacement of the drive motor is increased until the torque corresponding to the collected hydraulic pressure value of the drive motor is not less than the rated torque.

[0078] Figure 4 This is a schematic diagram illustrating the relationship between engine speed and fuel consumption obtained from testing in a fuel control method with a controllable vibration source provided in an embodiment of the present invention. Figure 3 and Figure 4 As shown, in this embodiment, the power unit is horsepower (BHP), and the fuel consumption unit is pounds per horsepower. Through the tests in this embodiment, the fitting formula for the total fuel consumption of the internal combustion engine at various speeds can be obtained as follows:

[0079] Total fuel consumption = fuel consumption per engine speed x power x fitting coefficient.

[0080] In this embodiment, the fitting coefficient is a constant. As an optional embodiment, the fitting coefficient is 0.4536 × 1.19.

[0081] In this embodiment, taking a fuel engine with speeds of 1800 rpm and 1600 rpm as examples, the fuel consumption at 1800 rpm is 0.368 lb-ft / hp and the power is 475 hp, while the fuel consumption at 1600 rpm is 0.366 lb-ft / hp and the power is 453 hp. The total fuel consumption is calculated as follows:

[0082] Fuel consumption at 1800 rpm: 0.368 × 475 × 0.4536 × 1.19 = 94.35 (L);

[0083] Fuel consumption at 1650 rpm: 0.366 × 453 × 0.4536 × 1.19 = 89.4951 (L);

[0084] In this embodiment, the fuel saving per hour is: 94.35 - 89.4951 = 4.85 (L);

[0085] Fuel savings percentage: 4.85 ÷ 94.35 × 100% = 5.1456%.

[0086] In this embodiment, by sensing the pressure in real time, the engine speed is intelligently and automatically adjusted between 1800 rpm under vibration and 1600 rpm under driving conditions, which can save more than 5% of fuel.

[0087] This embodiment of the fuel control system for a fuel engine based on a controllable vibration source utilizes the correlation between the torque, speed, and fuel consumption performance of the fuel engine. By adaptively controlling and adjusting the displacement of the drive motor and the speed of the fuel engine, it achieves the goal of reducing fuel consumption of the fuel engine while maintaining the same vehicle speed, even if the speed of the fuel engine is reduced, by resetting the displacement of the drive motor, thus ensuring the vibration output and transfer efficiency of the controllable vibration source. This achieves the goals of reducing operating costs, saving energy and reducing emissions, promoting green development, and extending the service life of the fuel engine.

[0088] This embodiment provides a fuel control system for a controllable vibration source. During the operation of the controllable vibration source, the speed of the fuel engine can be adjusted according to the different operating states of vibration and drive, i.e., based on the weight and load of the controllable vibration source. This eliminates the need to stop the controllable vibration source and does not occupy production time. It achieves fuel control that ensures production efficiency and site handling efficiency during the operation of the controllable vibration source, thereby reducing fuel consumption and production costs. It effectively solves the problem of high fuel consumption of the controllable vibration source engine in controllable vibration source construction projects, achieves optimal fuel consumption, and effectively reduces carbon emissions.
