Description

Technical Field

[0001] The present invention belongs to the technical field of dual-motor hybrid vehicle control, and specifically relates to an intelligent drive series motor. Background Art

[0002] In mining transportation scenarios, mining trucks (mining trucks) need to frequently undertake overloaded transportation tasks of fully loaded ore and other heavy objects. Especially under long-distance steep slope conditions, the contradiction between vehicle power performance and energy consumption management is particularly prominent. The traditional single-motor drive system is limited by the maximum torque output of a single power source, and it is difficult to continuously meet the high-intensity power demand when climbing with heavy loads. It is prone to problems such as insufficient power and reduced efficiency, which not only affects transportation efficiency, but also poses the risk of equipment loss due to motor overload. In addition, the mining operating environment is complex and the slope changes frequently. It is difficult for a single motor to flexibly adjust the power output according to the real-time working conditions. It often runs at a constant high power, resulting in serious waste of electricity, exacerbating the pain point of insufficient endurance of mining trucks. Therefore, how to achieve energy consumption optimization and endurance improvement while ensuring heavy-load climbing power performance has become a technical problem that needs to be solved urgently in the field of mining equipment. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the present invention provides an intelligent drive series motor. The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0004] The present invention provides an intelligent drive series motor, which is arranged on a mining truck, and comprises: a dual series motor, a drive unit, an intelligent control unit and a sensor unit;

[0005] The intelligent control unit is electrically connected to the sensor unit and the drive unit respectively; the sensor unit is used to monitor the motor parameters of the dual series motor and the driving parameters of the mining truck, and send the motor parameters and the driving parameters to the intelligent control unit; the intelligent control unit is used to determine whether the dual series motor fails according to the values ​​of the motor parameters; in the case of a failure of the dual series motor, a driving state judgment result is generated based on the driving parameters and the motor parameters, and an industrial control instruction for controlling the working state of the dual series motor is generated according to the driving state judgment result, wherein the driving state judgment result includes: a climbing state and a downhill state; and, in the case of a failure of the dual series motor, a fault protection control instruction is generated; the drive unit is used to drive the dual series motor to work in response to the industrial control instruction or the fault protection control instruction.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] In view of the problem that the existing electrodes applied to mining trucks are difficult to flexibly adjust the power output according to the real-time working conditions, resulting in serious waste of electric energy and exacerbating the insufficient endurance of mining trucks, the present invention provides an intelligent drive series motor applied to mining trucks. This motor superimposes torques through a dual-motor series architecture to output a doubled driving force, effectively solving the problem of insufficient power of heavy-duty mining trucks in long and steep slope scenarios. Secondly, based on the motor parameters (such as temperature and speed) and vehicle driving parameters (slope and load) collected in real time by sensors, the intelligent control unit can dynamically identify the climbing / descending state and intelligently switch between single / double motor modes in combination with the remaining power. While ensuring full-power output on steep slopes, it optimizes the energy consumption on flat sections, achieving an efficient balance between power and endurance. Finally, the system is built-in with a fault diagnosis and protection mechanism, which triggers protection strategies such as load reduction and switching to standby motors in a timely manner through abnormal parameter monitoring, greatly reducing the shutdown risk caused by motor overheating or overload and enhancing the system robustness. This design breaks through the technical bottleneck that it is difficult to balance the energy efficiency and reliability of traditional drive systems, providing an intelligent and highly adaptable power solution for heavy-duty mining transportation equipment.

[0017] Now, in combination with the accompanying drawings, a smart drive series motor provided by the present invention will be described in detail.

[0018] Figure 1 It is a structural block diagram of a smart drive series motor provided by the present invention. As Figure 1 shown, the smart drive series motor is arranged on a mining truck, and the smart drive series motor includes: a double series motor, a drive unit, a smart control unit, and a sensor unit; the smart control unit is electrically connected to the sensor unit and the drive unit respectively; the sensor unit is used to monitor the motor parameters of the double series motor and the driving parameters of the mining truck, and send the motor parameters and the driving parameters to the smart control unit; the smart control unit is used to judge whether the double series motor fails according to the value of the motor parameters; in the case of the double series motor failing, based on the driving parameters and the motor parameters, generate a driving state judgment result, and according to the driving state judgment result, generate an industrial control instruction for controlling the working state of the double series motor, wherein the driving state judgment result includes: a climbing state and a downhill state; and, in the case of the double series motor being in a fault, generate a fault protection control instruction; the drive unit is used to drive the double series motor to work in response to the industrial control instruction or the fault protection control instruction.

[0019] After the description of the structure of the double series motor is completed, now the sensor unit will be described in detail. The sensor unit includes various types of sensors with different functions, which can closely monitor the motor working state and the vehicle driving state. For example, a temperature sensor is used to monitor the motor temperature, a slope sensor is used to monitor the driving slope, a current sensor is used to monitor the motor current, and so on. Here, the motor parameters collected by the sensor unit include: motor speed, motor current, motor temperature, and motor output power, and the driving parameters include: vehicle body weight, cargo weight, driving speed, and driving slope.

[0020] Now, the specific composition of the smart control unit will be described in detail.

[0021] Figure 2 It is a structural block diagram of the smart control unit provided by the present invention. As Figure 2As shown in the figure, the intelligent control unit includes: an industrial control instruction generation sub-unit, a fault handling sub-unit, and a cooling sub-unit.

[0022] Specifically, the double series-connected motor includes: a first motor and a second motor connected in series. The structures and models of both are exactly the same. The industrial control instruction generation sub-unit is used to generate a first industrial control instruction to control the first motor and the second motor to work synchronously when the driving state judgment result is a climbing state; and generate a second industrial control instruction to control the first motor and / or the second motor to work when the driving state judgment result is a downhill state. When both the first motor and the second motor are working, the corresponding output power is less than the maximum output power.

[0023] Here, the intelligent control unit obtains the motor parameters and driving parameters returned by the sensor unit in real time, first determines whether there is a motor fault, and determines the current driving state of the vehicle based on the comparison of the two parameters in the case of determining that the motor is working normally. Exemplarily, when the vehicle is traveling at a constant speed, considering different vehicle loads, the power output by the motor corresponds to a range of vehicle speeds. When climbing a slope, the vehicle speed will be less than this range of vehicle speeds. When going downhill (without decelerating or braking), the vehicle speed will exceed this range of vehicle speeds.

[0024] Here, when controlling the first motor and the second motor to work synchronously in response to the first industrial control instruction, if the slope is not large (for example, between 20° and 60°), the output power of the two motors is regulated to be relatively low, which can not only maintain the vehicle's stable climbing but also minimize power consumption to the greatest extent. If the slope is steep (for example, between 60° and 90°), it means that the vehicle needs a greater driving force to overcome resistances such as gravity, and it is necessary to control the two motors to work at the maximum power to generate a large enough torque to drive the vehicle to overcome the huge resistance brought by the steep slope, ensuring that the vehicle can climb steadily upward and smoothly pass through the critical stage with the heaviest load and the greatest climbing difficulty.

[0025] Here, during the downhill process, since the mining truck itself has a large mass and large inertia, there is no need to drive the motor to work during downhill, or only rely on a single motor with higher efficiency and relatively lower energy consumption to work. It should be noted that although the two motors have the same type and structure, their usage times are not necessarily the same. Therefore, there are differences in efficiency and energy consumption.

[0026] A fault handling sub-unit is used to, when it is determined that the dual series-connected motors are in a fault situation, judge whether both the first motor and the second motor are in a fault based on the motor parameters of the first motor and the motor parameters of the second motor; when the first motor or the second motor is in a fault, generate a power adjustment instruction to adjust the output power of the second motor or the first motor so that the output power of the second motor or the first motor is within a preset power protection range; when both the first motor and the second motor are in a fault, generate a stop work instruction. And, the fault handling sub-unit is further used to generate a fault prompt message when it is determined that the first motor and / or the second motor is in a fault.

[0027] Here, because a dual series-connected motor is set in the mining truck, even if one of the motors fails, the other motor may still maintain a certain power output, enabling the mining truck to continue to complete climbing or move to a safe area to wait for repair, greatly improving the reliability and fault tolerance of the entire drive system in the heavy-load climbing scenario. Specifically, after the fault handling sub-unit determines that a motor has a fault, it first checks the number and specific location of the faulty motors to evaluate the severity and type of the fault. If the fault is minor, the fault handling sub-unit will try to adjust the working parameters of the motor to restore normal operation. If the fault is relatively serious, the fault handling sub-unit will re-adjust the power distribution according to the actual requirements of the vehicle and the performance parameters of the motor to ensure that the motors that can work normally can provide sufficient power output. Here, when one of the motors fails, the driving stability of the vehicle may be affected to a certain extent. The intelligent control unit will also adjust the braking system, steering system, etc. of the vehicle to try to maintain the driving stability of the vehicle. And, corresponding fault prompt messages are displayed through the dashboard of the vehicle to remind the driver to park the vehicle in a safe place as soon as possible and contact professional maintenance personnel for repair.

[0028] Here, in order to ensure the safe operation of the motors that can work normally, the intelligent control unit is also equipped with various protection mechanisms. For example, when one motor fails, the fault handling sub-unit will limit the output power of the other motor that can work normally to prevent the motor from being overloaded.

[0029] A cooling sub-unit is used to cool the first motor and the second motor when it is determined that the first motor and / or the second motor is in a fault. Cooling the motors through the cooling sub-unit can prevent the motors from being damaged due to overheating.

[0030] Here, please continue to refer to Figure 1, the intelligent drive series motor further includes: a kinetic energy recovery unit; the kinetic energy recovery unit is electrically connected to the intelligent control unit and is used for, when the driving state determination result is a downhill state, in response to the start kinetic energy recovery instruction sent by the intelligent control unit, converting the mechanical kinetic energy of the mining truck into electric energy and storing the electric energy in the battery pack provided on the mining truck. Moreover, the kinetic energy recovery unit is further used for obtaining the remaining power and battery temperature of the battery pack, determining whether the remaining power reaches the maximum value, and whether the battery temperature is within the preset temperature range; in the case where the remaining power reaches the maximum value or the battery temperature exceeds the preset temperature range, stopping the kinetic energy recovery.

[0031] Specifically, when the mining truck is going downhill, the kinetic energy recovery unit controls the motor to switch from the driving mode to the power generation mode, so as to convert the mechanical function of the mining truck into electric energy by using the principle of electromagnetic induction, and this electric energy is transmitted to the battery pack through the circuit. It should be noted that the kinetic energy recovery unit will control the charging current and voltage according to the current state of the battery pack, such as power, temperature, etc., to achieve the best charging effect. At the same time, the kinetic energy recovery unit will also monitor the charging process to prevent overcharging, overheating and other situations.

[0032] Here, by using two motors to carry out kinetic energy recovery simultaneously, compared with a single motor, it can recover the kinetic energy of the vehicle during downhill braking more comprehensively. The two motors can share the task of energy recovery, so as to convert the kinetic energy of the vehicle into electric energy in a shorter time and effectively improve the efficiency of energy recovery.

[0033] Here, the kinetic energy recovery unit is further used for, when the driving state determination result is a climbing state, supplying power to the double series motor by using the electric energy stored in the battery pack. Specifically, when the vehicle accelerates, the electric energy stored in the battery pack is instantaneously released to drive the double series motor to operate, effectively increasing the cruising range of the mining truck.

[0034] Here, the specific structures of the first motor and the second motor are described. Figure 3 is the overall structure diagram of the first motor provided by the present invention, Figure 4 is the overall structure diagram of the first motor from another perspective provided by the present invention, Figure 5 is the half-sectional view of the first motor provided by the present invention, Figure 6 is the half-sectional view of the first motor from another perspective provided by the present invention. Here, for the convenience of description, Figures 3 to 6 some important components in

[0035] such as Figure 3 shown, the numbers 001 and 002 are both the U, V, W three-phase cable ports of the first motor, and their function is high-voltage input. By changing the wiring order of any two of the U, V, W three-phase lines, the phase sequence of the current in the stator winding can be changed, so as to change the rotation direction of the rotating magnetic field.

[0036] Serial number 003 is a lifting ring, used for lifting and handling.

[0037] Serial number 004 is a connecting flange, whose function is to connect the coupling. The rigid coupling directly connects the motor shaft and the transmission shaft through connecting parts such as bolts and keys to achieve rigid power transmission. This coupling has a simple structure and high transmission efficiency.

[0038] Serial number 005 is the output internal spline sleeve of the second motor, whose function is to connect the outer spline shaft of the coupling.

[0039] Serial number 006 are two groups of motor mount fixing holes on the left and right, whose function is to support and fix. After installing the mounts, it is connected to the vehicle chassis.

[0040] Serial number 007 is the motor housing. Its function is that the cast aluminum housing is relatively light in weight, has relatively high heat dissipation and thermal conductivity coefficients, and can more effectively conduct the heat generated inside the motor to the outside. It can well play the role of IP68 protection level.

[0041] Serial number 008 is a cable fixing bracket, whose function is to accurately position the cable at the required position. Avoid cable entanglement or misalignment, making the entire cable layout clear and organized. When subjected to external forces such as wind, vibration, or collision with other equipment, the cable may shift. The structure is convenient for installation, maintenance, and repair.

[0042] Serial number 009 is a cable gland. Its function is to provide reliable sealing to prevent rainwater, dust, moisture, corrosive liquids (such as acid and alkali solutions in chemical factories), and various gases (such as flammable and explosive gases) from entering the equipment interior. The hard structure of the gland can buffer and disperse the externally applied pressure, friction, and tensile force. Reduce electromagnetic interference (EMI) and radio frequency interference (RFI). The gland with electromagnetic shielding function can effectively reduce the influence of external electromagnetic interference on the cable transmission signal, and at the same time prevent the electromagnetic radiation generated by the cable internal signal from leaking into the external environment.

[0043] As Figure 4 shown, serial number 10 is a liquid flow balance sensor. Its function is to cooperate with the pressure balance sensor to control the flow rate of the coolant entering the motor by adjusting the flow regulating valve of the water inlet nozzle. The appropriate flow rate is crucial for the cooling effect of the motor. For example, in the cooling of high-precision motors, too large a flow rate may cause too high internal pressure in the motor, damaging the motor seal and structure; too small a flow rate cannot effectively take away the heat generated by the motor. By controlling the flow rate through the water inlet nozzle, the cooling effect can be optimized according to the actual operating conditions of the motor (such as load size, operating environment temperature, etc.).

[0044] No. 011 is the motor water outlet nozzle. Its function is that hot water flows out of the motor through the outlet nozzle and then enters an external heat exchanger (such as a radiator) for cooling.

[0045] No. 012 is the pressure balance sensor. Its function is that during the circulation of the coolant inside the motor, its volume changes with temperature. When the coolant temperature rises, the volume expands. The existence of the outlet nozzle can provide a discharge channel for the coolant, thus balancing the pressure generated inside the motor due to the change in liquid volume. This pressure balance helps to maintain the normal operation of the motor cooling system and prevent problems such as the rupture of the cooling pipeline or the damage of other sealing components caused by excessive internal pressure.

[0046] No. 013 is the motor water inlet nozzle. Its function is to be the starting point of a complex pipeline network, the "water supply system".

[0047] No. 014: Resolver communication port. Its function is for motor position detection and speed feedback to achieve vector control of the motor. The position information provided by the resolver enables the motor controller to accurately decompose the current, thereby achieving independent control of the motor magnetic field and torque, optimizing the operating performance of the motor, and regulating the motor drive with high precision.

[0048] As Figure 5 shown, No. 015 is the coolant circulation channel. Its function is that during the operation of the motor, since current passing through the winding generates joule heat, and at the same time the iron core of the motor also generates iron loss heat when the magnetic field changes. These heats will cause the motor temperature to rise. The coolant circulation channel can transport the coolant to the heat-generating parts of the motor, such as around the stator winding and the iron core. After the coolant absorbs heat, it takes the heat away, thus effectively reducing the motor temperature, extending the service life of the motor, and ensuring the safe and stable operation of the motor.

[0049] No. 016 and 017 are the motor stator windings. Its function is that when three-phase alternating current is applied to the stator windings, a rotating magnetic field will be generated inside the motor. This rotating magnetic field will cut the rotor conductors, thereby generating induced electromotive force and induced current in the rotor windings. According to the law of electromagnetic induction, a current-carrying conductor will be subjected to a force in a magnetic field, causing the rotor to rotate following the rotating magnetic field, thus achieving the electromechanical energy conversion of the motor.

[0050] As Figure 6 shown, No. 018 and 019 are the motor shafts. Its function is to transmit the power generated by the motor rotor to external equipment for the normal operation of the motor. At the same time, it also plays a role in supporting the windings, ensuring that the windings can rotate stably inside the motor. Because during the operation of the motor, the rotor rotates at high speed. Without the stable support provided by the motor shaft, the rotor is prone to problems such as eccentricity and vibration, thus affecting the performance and service life of the motor.

[0051] In view of the problem that it is difficult for existing electrodes used in mining trucks to flexibly adjust power output according to real-time working conditions, resulting in serious waste of electric energy and exacerbating the problem of insufficient endurance of mining trucks, the present invention provides an intelligent drive series motor used in mining trucks, which has the following technical effects:

[0052] (1) Power performance and energy efficiency optimization

[0053] The dual series motors use the same structure, providing multiplied driving force through torque superposition, combined with the high-precision position detection and vector control of the resolver communication port, to ensure full power output of the dual motors in the steep slope (60°~90°) stage, effectively overcoming heavy load resistance; in the gentle slope (20°~60°) or flat road stage, the single / dual motor low-power mode is intelligently switched to reduce energy consumption. The kinetic energy recovery unit converts mechanical energy into electrical energy storage when going downhill, and dynamically adjusts the charging process according to the battery status to improve endurance.

[0054] (2) Intelligent fault tolerance and system protection

[0055] The intelligent control unit diagnoses the status of the dual motors in real time based on multi-sensor data such as temperature and current. When a single motor fails, the fault processing subunit automatically adjusts the power of the other motor to a safe range to maintain basic power output, and links the cooling subunit to start the liquid cooling cycle (precisely controlling the coolant flow and pressure through the liquid flow balance sensor and pressure balance sensor) to prevent overheating and damage; when both motors fail, they are forced to shut down and the braking system is triggered to stabilize the vehicle body, significantly improving system reliability and fault tolerance.

[0056] (3) Structural reinforcement and thermal management optimization

[0057] The cast aluminum housing (IP68 protection) is combined with a cooling liquid circulation channel to efficiently conduct heat from the stator winding and core, extending the life of the motor; the cable fixing bracket and shielded cable gland ensure that the line is anti-interference, dustproof and waterproof, and adapts to the harsh environment of the mine; the rigid coupling coupler and suspension fixing hole design enhance the stability of power transmission.

[0058] (4) Adaptive control and dynamic response

[0059] The industrial control command generation subunit determines the climbing / descending state in real time based on vehicle weight, slope, speed and other parameters, and dynamically adjusts the dual-motor coordination strategy to achieve the optimal match between power output and energy consumption. The system overcomes the problems of insufficient power, short battery life and high risk of failure of traditional mining trucks, and provides an intelligent and highly robust power solution for heavy-load transportation in mines.

[0060] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as falling within the protection scope of the present invention.
