Description
Technical Field
[0001] The present invention relates to the technical field of engineering machinery, and in particular to a power supply control system and method for continuous wall construction equipment. Background Art
[0002] The underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous reinforced concrete wall underground as a water-stopping, soil-retaining, maintenance, and load-bearing structure.
[0003] At present, the continuous wall grab in the market generally uses the engine as the power source. The engine burns oil to generate kinetic energy to drive the hydraulic pump. The hydraulic system realizes the functions of the whole machine through hydraulic pump, valve group, hydraulic motor, hydraulic cylinder and other components. Among them, the hydraulic motor drives the winch to roll the wire rope, and the wire rope drives the working system to realize the lifting and lowering of the working system.
[0004] However, practice has found that when the engine is working, it usually produces exhaust emissions, which need to be purified; and when the working system brakes, the energy is converted from kinetic energy to heat energy, which requires energy consumption to dissipate heat, which easily leads to energy waste, that is: the traditional way of working the engine to power the continuous wall grab, in addition to providing kinetic energy, also needs to work according to the changes in the environment during the power supply process, which easily leads to resource waste.

The following are detailed descriptions.
[0079] Embodiment 1
[0080] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a power supply control system for continuous wall construction equipment disclosed in an embodiment of the present invention. Figure 1 The power supply control system of the continuous wall construction equipment described can be applied to the working scene of the continuous wall construction equipment (such as a continuous wall grab). Optionally, the system can be integrated into the continuous wall construction equipment, or can exist independently of the continuous wall construction equipment, or can be a local server or cloud server for processing the power supply process of the continuous wall construction equipment, etc., which is not limited in the embodiments of the present invention. Figure 1 As shown, the power supply control system of the continuous wall construction equipment may include:
[0081] High voltage power distribution unit 101, used to determine the whole machine operating power required for the current action of the continuous wall construction equipment;
[0082] The high-voltage power distribution unit 101 is further used to control the on-board charger and / or the power battery in the battery management system to perform a first power supply control operation on the motor controller 102 according to the operating power of the whole machine;
[0083] The motor controller 102 is used to control the pump motor to provide power to the whole hydraulic system of the continuous wall construction equipment and control the winch motor to provide power to the winch device of the continuous wall construction equipment under the power supply control of the high-voltage power distribution unit 101;
[0084] The motor controller 102 is also used to detect the current state of the hoisting motor, and perform a second power supply control operation through the high-voltage power distribution unit 101 according to the current state of the hoisting motor and the operating power of the whole machine.
[0085] In an embodiment of the present invention, an on-board charger and a power battery are used as dual power sources, and under the power supply of the dual power sources, the pump motor is controlled to provide power for the hydraulic system of the entire machine to replace the engine in the prior art, and the winch motor is controlled to provide power for the winch device to replace the hydraulic motor in the prior art. In this way, precise power supply to the continuous wall grab can be achieved while reducing the waste of resources caused by exhaust gas purification due to exhaust emissions and energy consumption for heat dissipation due to energy conversion into heat energy.
[0086] Specifically, the whole machine operating power may be a first preset power or a second preset power, and the second preset power is greater than the first preset power, wherein the first preset power is used to indicate the power of the whole machine when it is in a low-power operating state, and the second preset power is used to indicate the power of the whole machine when it is in a full-power operating state. The current state of the hoisting motor may include a preset hoisting rising state or a preset hoisting lowering state, wherein the hoisting lowering state may include a state of hoisting lowering and / or braking.
[0087] Optionally, the number of on-board chargers may be 5, 4, or any other set value. Optionally, the first power supply control operation may include the operation of the on-board charger supplying power to the motor controller 102, or the operation of the on-board charger and the power battery supplying power to the motor controller 102 together. Optionally, the second power supply control operation may include the operation of controlling the on-board charger and the power battery to supply power to the motor controller 102 together through the high-voltage distribution unit 101, or the operation of controlling the winch motor to recharge the power battery and supply power to the pump motor through the high-voltage distribution unit 101, which is not limited in the embodiments of the present invention.
[0088] It can be seen that the implementation Figure 1The described power supply control system of continuous wall construction equipment can be set as a dual power source by setting a vehicle charger and a power battery in a battery management system, and the dual power source drives the winch motor to provide power for the winch device and drives the pump motor to provide power for the hydraulic system of the whole machine, so as to quickly and accurately realize the driving control of the continuous wall construction equipment. Compared with the existing power supply mode of continuous wall construction equipment (i.e., the engine is used as the power source, the engine burns oil to generate kinetic energy to drive the hydraulic pump, and the hydraulic system realizes various functions of the whole machine through components such as the hydraulic pump, valve group, hydraulic motor, hydraulic cylinder, etc.), a power supply control system and method that is efficient, automatic and can be powered by multiple power sources at the same time is provided, which not only reduces the waste of resources caused by exhaust gas purification due to the generation of exhaust gas emissions and the consumption of energy for heat dissipation due to the conversion of energy into heat energy, but also improves the power supply efficiency and accuracy of the continuous wall construction equipment, and can improve the power supply diversity and flexibility of the continuous wall construction equipment through the flexible selection of diversified power sources, ensuring the reliability and accuracy of the power supply to the continuous wall construction equipment, thereby facilitating the improvement of the driving efficiency and driving accuracy of the continuous wall construction equipment, and further facilitating the improvement of the working efficiency of the continuous wall construction equipment.
[0089] In an optional embodiment, the high-voltage power distribution unit 101 controls the on-board charger and / or the power battery in the battery management system to perform the first power supply control operation on the motor controller 102 according to the whole machine operating power, which may specifically include:
[0090] Determine the power source corresponding to the motor controller 102 according to the whole machine operating power;
[0091] When the power source includes an on-board charger, the first electric energy corresponding to the received on-board charger is provided to the motor controller 102 and the power battery;
[0092] When the power source includes an on-board charger and a power battery, the first electric energy corresponding to the on-board charger and the second electric energy received from the power battery are provided to the motor controller 102 .
[0093] In an embodiment of the present invention, the power source includes an on-board charger, or the power source includes an on-board charger and a power battery in a battery management system.
[0094] In the embodiment of the present invention, specifically, the first electric energy corresponding to the on-board charger may be electric energy provided by high-voltage direct current obtained by converting the alternating current output by the on-board charger through a direct current conversion module in the power supply control system.
[0095] It can be seen that this optional embodiment can control the on-board charger and / or power battery to switch the power source based on the whole machine operating power through the high-voltage distribution unit 101, so as to accurately determine the power source for the motor controller 102, and quickly and accurately control the power supply to the motor controller 102 based on the accurately determined power source. Compared with the existing method of the engine burning oil to generate kinetic energy to drive the hydraulic pump, the emission of exhaust gas and the conversion of kinetic energy into heat energy are reduced. In this way, not only the waste of resources is reduced, but also the power supply efficiency and accuracy of the continuous wall construction equipment are improved, as well as the power supply flexibility and diversity of the continuous wall construction equipment are improved, which is conducive to improving the subsequent driving accuracy and efficiency of the continuous wall construction equipment.
[0096] In this optional embodiment, as an optional implementation, the high-voltage power distribution unit 101 determines the power source corresponding to the motor controller 102 according to the whole machine operating power, which may specifically include:
[0097] When the whole machine operating power is the first preset power, the on-board charger is determined as the power source corresponding to the motor controller 102;
[0098] When the whole machine operating power is the second preset power, the on-board charger and the power battery are determined as the power sources corresponding to the motor controller 102 .
[0099] In the embodiment of the present invention, the motor controller 102 may optionally include a pump motor controller for controlling a pump motor, and may also include a hoisting motor controller for controlling a hoisting motor. Optionally, the number of hoisting motors may be greater than 1 (e.g., 2), and each hoisting motor corresponds to a hoisting motor controller. For example, assuming that the power supply control system includes a hoisting motor A and a hoisting motor B, the hoisting motor controller may include a hoisting motor controller a corresponding to hoisting motor A and a hoisting motor controller b corresponding to hoisting motor B.
[0100] For example, Figure 2 As shown, Figure 2 Schematic diagram of a system power supply direction when the whole machine is running at low power according to an embodiment of the present invention. Figure 2 As shown, when the whole machine is running at low power, the high voltage distribution unit 101 (such as Figure 2 The PDU in the vehicle will charge the vehicle (such as Figure 2 The converted electrical energy provided by the OBC in the motor controller 102 (such as Figure 2 The pump motor controller, winch motor controller 1 and winch motor controller 2) in the apparatus can charge the power battery at the same time.
[0101] For example, Figure 3 As shown, Figure 3 is a schematic diagram of another system power supply direction when the whole machine is running at full power disclosed in an embodiment of the present invention, such as Figure 3 As shown, when the whole machine is running at full power, the high-voltage power distribution unit 101 supplies power to the motor controller 102 together with the converted electric energy provided by the on-board charger and the electric energy provided by the power battery.
[0102] It can be seen that this optional implementation can directly use the on-board charger as the power source corresponding to the motor controller 102 when the whole machine is running at low power, and determine the on-board charger and the power battery as the power source corresponding to the motor controller 102 when the whole machine is running at full power. This can improve the accuracy, flexibility and diversity of determining the power source for powering the motor controller 102, and is beneficial to improving the power supply accuracy and reliability of the motor controller 102 based on the on-board charger when the whole machine is running at low power, and is beneficial to improving the power supply speed and power supply efficiency of the motor controller 102 based on the dual power sources of the on-board charger and the power battery when the whole machine is running at full power.
[0103] In another optional embodiment, the motor controller 102 may perform the second power supply control operation through the high-voltage power distribution unit 101 according to the current state of the hoisting motor and the operating power of the whole machine, and the specific manner may include:
[0104] When the current state of the hoisting motor is the preset hoisting lifting state, the high-voltage power distribution unit 101 is controlled to provide the first electric energy corresponding to the on-board charger and the second electric energy output by the power battery to the motor controller 102;
[0105] When the current state of the hoisting motor is the preset hoisting lowering state, determining whether the whole machine operating power is the first preset power;
[0106] When it is determined that the whole machine operating power is the first preset power, the hoisting motor is controlled to perform a third power supply control operation.
[0107] In the embodiment of the present invention, optionally, the winch lifting may occur when the whole machine is running at low power, or when the whole machine is running at full power, or when running at other set power, which is not limited in the embodiment of the present invention.
[0108] For example, Figure 4 As shown, Figure 4 Schematic diagram of the power supply direction of a system during winch lifting disclosed in an embodiment of the present invention, such as Figure 4As shown, when the winch is lifted, the high-voltage power distribution unit 101 controls the electric energy to flow from the on-board charger and the power battery to the motor controller 102, driving the winch device to rotate, thereby improving the working efficiency of the working device of the continuous wall construction equipment, such as Figure 5 As shown, Figure 5 The present invention discloses a working device of a continuous wall construction device, wherein the working device includes a winch device. Figure 5 The schematic diagram on the left is a working device, and the schematic diagram on the left (the device indicated by the arrow) is a zoomed view of the winch device included in the working device on the left.
[0109] It can be seen that this optional embodiment can control the high-voltage distribution unit 101 to perform the operation of providing the first electric energy corresponding to the on-board charger and the second electric energy output by the power battery to the motor controller 102 when the winch is lifted, and can realize the drive control of the winch device by continuously supplying power to the motor controller 102 by the high-voltage distribution unit 101, thereby helping to improve the working efficiency of the working device; when the winch is lowered, it is determined whether the whole machine is currently in a low-power operation state. If so, the winch motor is controlled to perform the third power supply control operation, which can improve the control accuracy and reliability of power generation through the winch motor when the winch is lowered and the whole machine is running at low power, which is conducive to realizing the recycling of excess energy resources, thereby helping to reduce the waste of energy resources to a certain extent.
[0110] In this optional embodiment, as an optional implementation manner, the manner in which the motor controller 102 controls the hoisting motor to perform the third power supply control operation specifically includes:
[0111] Controlling the hoisting motor to enter a power generation state, and receiving the initial energy output by the hoisting motor in the power generation state;
[0112] The energy form of the initial energy is converted from gravitational potential energy to electrical energy to obtain target energy, and the target energy is provided to the high-voltage power distribution unit 101 .
[0113] In the embodiment of the present invention, specifically, when the winch is lowered and braked, the winch motor is in a state of reverse rotation with positive torque, enters a power generation state, and changes from an electric motor to a generator. At this time, the winch motor controller recovers the gravitational potential energy of the winch being lowered, and converts the gravitational potential energy into electrical energy, and provides the converted electrical energy to the high-voltage distribution unit 101 for use.
[0114] It can be seen that this optional implementation can control the winch motor to enter the power generation state through the motor controller 102 when the winch is lowered and braked, and receive the initial energy output by the winch motor in the power generation state, which can improve the motor controller 102 The accuracy and efficiency of recovering the energy output by the winch motor, and convert the energy form of the initial energy from gravitational potential energy to electrical energy to obtain target energy, and provide the target energy to the high-voltage distribution unit 101, and can achieve accurate and effective utilization of excess energy resources through the conversion output of the recovered energy by the motor controller 102, which is conducive to reducing the waste of energy resources to a certain extent.
[0115] In this optional implementation manner, optionally, the high voltage distribution unit 101 is further used for:
[0116] Receiving the target energy output by the motor controller 102, and detecting a first charging requirement state of the power battery and a second charging requirement state of the pump motor;
[0117] According to the first charging requirement state and the second charging requirement state, selecting a power supply object of target energy from the power battery and the pump motor;
[0118] The target energy output by the motor controller 102 is provided to the power supply object.
[0119] In the embodiment of the present invention, specifically, when the high-voltage distribution unit 101 receives the target energy output by the winch motor controller, it detects whether the power battery and the pump motor have charging requirements, and based on the detection results, flexibly selects the objects that need to be charged, and then distributes the target energy to the objects that need to be charged.
[0120] For example, when both the power battery and the pump motor have charging requirements, the high-voltage power distribution unit 101 provides part of the target energy to the power battery, and provides part of the target energy to the pump.
[0121] For example, Figure 6 As shown, Figure 6 Schematic diagram of a winch lowering and system power supply direction during formulation disclosed in an embodiment of the present invention, such as Figure 6 As shown, when the winch is lowered and braked, the winch motor is in a state of reverse rotation with positive torque and enters a power generation state. At this time, the winch motor changes from an electric motor to a generator. The winch motor controller recovers the gravitational potential energy when the winch is lowered through the winch motor, and converts the gravitational potential energy into electrical energy, which is then recharged to the power battery through the high-voltage distribution unit 101. At the same time, part of the electrical energy is provided to the pump motor for use.
[0122] It can be seen that this optional implementation can also receive the target energy output by the motor controller 102 through the high-voltage distribution unit 101, and detect the charging demand status of the power battery and the pump motor, and then screen out the power supply objects of the target energy from the power battery and the pump motor according to the charging demand status, which can improve the detection accuracy of the charging demand of the power battery and the pump motor, thereby improving the screening accuracy of the power supply objects of the target energy, and then providing the target energy output by the motor controller 102 to the power supply object, which can improve the accuracy of the distribution of the target energy by the above-mentioned high-voltage distribution unit 101, and can improve the accuracy, flexibility and diversity of providing the target energy to the power battery and / or pump motor.

[0125] A second DC voltage output by the DC conversion module is received, and the second DC voltage is determined as a basis for the high-voltage power distribution unit 101 to perform the first power supply control operation.
[0126] In the embodiment of the present invention, specifically, 380V AC power is introduced from the power grid, distributed and diverted to the OBC through the AC distribution box, and the OBC converts the 380V AC power into 600V high-voltage DC power. The high-voltage DC power is input into the DCDC DC conversion module through the high-voltage distribution unit 101 for voltage stabilization, and then the high-voltage distribution unit 101 is triggered to provide the stabilized DC power to the motor controller 102 according to the power usage of the whole machine.
[0127] For example, if Figure 7 As shown, Figure 7 is a schematic diagram of a power supply control device for continuous wall construction equipment disclosed in an embodiment of the present invention (the power supply control device can be understood as Figure 1 The power supply control device may include a PDU high-voltage power distribution unit, a DCDC direct current conversion module, a motor controller, a pump motor and a hoisting motor, wherein the motor controller may include a pump motor controller and a hoisting motor controller, and each hoisting motor corresponds to a hoisting motor controller, such as Figure 7As shown, two hoisting motors are taken as an example, and the hoisting motor controller includes a hoisting motor controller 1 and a hoisting motor controller 2. Specifically, the first end of the PDU high-voltage distribution unit is used to electrically connect to the first end of the OBC on-board charger, the second end of the PDU high-voltage distribution unit is used to electrically connect to the power battery in the BMS battery management system, the third end of the PDU high-voltage distribution unit is electrically connected to the DCDC direct current conversion module, and the fourth end of the PDU high-voltage distribution unit 101 is electrically connected to the first end of the pump motor controller, the first end of the hoisting motor controller 1 and the first end of the hoisting motor controller 2, respectively, the second end of the hoisting motor controller 1 and the second end of the hoisting motor controller 2 are electrically connected to the corresponding hoisting motors, the second end of the pump motor controller is electrically connected to the first end of the pump motor, the third end of the pump motor controller is used to electrically connect to the AC alternating current voltage, the fourth end of the pump motor controller is used to electrically connect to the PTC thermistor, and the second end of the pump motor is used to electrically connect to the hydraulic pump system.
[0128] It can be seen that this optional embodiment can receive the AC power introduced by the power grid through the collector, and distribute the AC power to the corresponding on-board charger through the distribution box, so as to realize accurate power supply to the on-board charger which is the power source of the power supply control system, and convert the AC voltage output by the distribution box received by the on-board charger into high-voltage DC power, and then the high-voltage DC power is stabilized by the high-voltage distribution unit 101 through the DC conversion module, and the stabilized DC voltage is then passed to the high-voltage distribution unit 101, which can improve the processing accuracy and reliability of the power supply source of the high-voltage distribution unit 101 used to power the motor controller 102.
[0129] Embodiment 2
[0130] See also Figure 8 , Figure 8 1 is a flow chart of a power supply control method for continuous wall construction equipment disclosed in an embodiment of the present invention. Figure 8 The power supply control method for continuous wall construction equipment described can be applied to the working scene of continuous wall construction equipment (such as continuous wall grab), such as Figure 8 As shown, the power supply control method of the continuous wall construction equipment may include the following operations:
[0131] 201. The high voltage distribution unit determines the whole machine operating power required for the current action of the continuous wall construction equipment.
[0132] 202. The high-voltage power distribution unit controls the on-board charger and / or the power battery in the battery management system to perform a first power supply control operation on the motor controller according to the whole machine operating power.
[0133] 203. Under the power supply control of the high-voltage distribution unit, the motor controller controls the pump motor to provide power for the entire hydraulic system of the continuous wall construction equipment, and controls the winch motor to provide power for the winch device of the continuous wall construction equipment.
[0134] 204. The motor controller detects the current state of the hoisting motor, and performs a second power supply control operation through the high-voltage power distribution unit according to the current state of the hoisting motor and the operating power of the whole machine.
[0135] It can be seen that the implementation Figure 8 The described power supply control method for continuous wall construction equipment can realize the driving control of continuous wall construction equipment quickly and accurately by setting the on-board charger and the power battery in the battery management system as dual power sources, and driving the winch motor to provide power for the winch device and driving the pump motor to provide power for the hydraulic system of the whole machine through the dual power sources. Compared with the existing power supply mode of continuous wall construction equipment (i.e., the engine is used as the power source, the engine burns oil to generate kinetic energy to drive the hydraulic pump, and the hydraulic system realizes various functions of the whole machine through the hydraulic pump, valve group, hydraulic motor, hydraulic cylinder and other components), a power supply control system and method that is efficient, automatic and can supply power to multiple power sources at the same time is provided, which not only reduces the waste of resources caused by exhaust gas purification due to the generation of exhaust gas emissions and the consumption of energy for heat dissipation due to the conversion of energy into heat energy, but also improves the power supply efficiency and accuracy of continuous wall construction equipment, and can improve the power supply diversity and flexibility of continuous wall construction equipment through the flexible selection of diversified power sources, ensuring the reliability and accuracy of power supply to continuous wall construction equipment, thereby facilitating the improvement of the driving efficiency and driving accuracy of continuous wall construction equipment, and further facilitating the improvement of the working efficiency of continuous wall construction equipment.

[0138] When the power source includes an on-board charger, the high-voltage power distribution unit provides the first electric energy corresponding to the received on-board charger to the motor controller and the power battery;
[0139] When the power source includes an on-board charger and a power battery, the high-voltage power distribution unit provides the motor controller with the first electric energy corresponding to the on-board charger and the second electric energy received from the power battery.
[0140] It can be seen that this optional embodiment can control the on-board charger and / or power battery to switch the power source based on the whole machine operating power through the high-voltage distribution unit, so as to accurately determine the power source for the motor controller, and quickly and accurately control the power supply to the motor controller based on the accurately determined power source. Compared with the existing method of the engine burning oil to generate kinetic energy to drive the hydraulic pump, it reduces the emission of exhaust gas and the conversion of kinetic energy into heat energy. In this way, it not only reduces the waste of resources, but also improves the power supply efficiency and accuracy of the continuous wall construction equipment, as well as the flexibility and diversity of the power supply to the continuous wall construction equipment, which is conducive to improving the subsequent driving accuracy and efficiency of the continuous wall construction equipment.

[0143] When the whole machine operating power is the second preset power, the high-voltage power distribution unit determines the on-board charger and the power battery as the power source corresponding to the motor controller, and the second preset power is greater than the first preset power.
[0144] It can be seen that this optional implementation method can directly use the on-board charger as the power source corresponding to the motor controller when the whole machine is running at low power, and determine the on-board charger and the power battery as the power source corresponding to the motor controller when the whole machine is running at full power. This can improve the accuracy, flexibility and diversity of determining the power source for powering the motor controller, and is beneficial to improving the power supply accuracy and reliability of the motor controller based on the on-board charger when the whole machine is running at low power, and is beneficial to improving the power supply speed and power supply efficiency of the motor controller based on the dual power sources of the on-board charger and the power battery when the whole machine is running at full power.

[0147] When the current state of the hoisting motor is the preset hoisting lowering state, the motor controller determines whether the whole machine operating power is the first preset power;
[0148] When it is determined that the whole machine operating power is the first preset power, the motor controller controls the hoisting motor to perform a third power supply control operation.
[0149] It can be seen that this optional embodiment can, when the winch is lifted, control the high-voltage distribution unit to execute the operation of providing the first electric energy corresponding to the on-board charger and the second electric energy output by the power battery to the motor controller, and can provide continuous power supply to the motor controller by the high-voltage distribution unit to realize drive control of the winch device, which is beneficial to improving the working efficiency of the working device; when the winch is lowered, it is determined whether the whole machine is currently in a low-power operation state. If so, the winch motor is controlled to execute the third power supply control operation, which can improve the control accuracy and reliability of power generation through the winch motor when the winch is lowered and the whole machine is running at low power, which is beneficial to realize the recycling of excess energy resources, thereby helping to reduce the waste of energy resources to a certain extent.
