Description

Technical Field

[0001] This utility model relates to an integrated branch line controller device and a crane, belonging to the field of engineering machinery technology. Background Technology

[0002] In the electrical systems of large-tonnage wheeled cranes, the displacement counterbalance and superlift systems have a similar basic structure and relatively independent functions. Therefore, the electrical systems of displacement counterbalance and superlift generally adopt modular design and distributed control, achieving advantages such as convenient networking, flexible configuration, and saving main control ports. However, due to the complexity of existing displacement counterbalance and superlift electrical control systems, based on the data from existing superlift system electrical design drawings, they consist of 3 controllers, 12 branch switches, 30 connectors, 51 solenoid valves, 37 digital inputs, 12 analog inputs, and more than 450 gas hoses, etc. A large number of wiring harnesses, connectors, and electrical components rely on manual manufacturing. The superlift and displacement counterbalance electrical systems have become the most complex systems in terms of wiring connections, the highest failure feedback rate, and the lowest production and assembly efficiency for large-tonnage cranes.

[0003] Currently, most other construction machinery manufacturers adopt centralized control or distributed control. For independent booms such as superlifts and displacement counterbalancers, they still use the controller + connector + junction box + prefabricated wiring harness mode as distributed nodes to network with the main control PLC.

[0004] With the widespread use of prefabricated wire harnesses, simplifying the fabrication and connection of wire harnesses and eliminating the unreliability, unsightly appearance, and time-consuming problems caused by manual wire harness fabrication are increasingly no longer sufficient to meet the requirements of automated, rapid connection, standardized, and efficient assembly of wire harnesses. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an integrated splitter controller device and crane. The integrated splitter controller integrates the controller, splitter, connector, and wire harness connection into one unit to achieve wire harness connection without wiring and quick connection. This eliminates the unreliability and low efficiency of manual wire harness fabrication, greatly improves assembly efficiency, reduces costs, and increases reliability.

[0006] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution: First aspect: An integrated splitter controller device, comprising a PCB circuit board, the PCB circuit board including a PCB main board and a PCB interface board, the PCB main board and the PCB interface board realizing communication and power supply between the two through a board-to-board connector; the PCB circuit board is disposed inside a housing; The PCB motherboard includes a CPU module and a DO module, a PWM module, a CAN communication module and a power module connected to the CPU module. The PCB interface board includes an AI / DI input module and a DIHL input module, which are connected to the CPU module. The housing has a digital output (DO) signal interface and a PWM output signal interface, a power interface and a CAN bus interface on one side, which are connected to the motherboard PCB. The other side of the housing is provided with an interface for connecting analog AI / DI input signals or DIHL digital input signals to the interface board PCB.

[0007] Optionally, the power lines, ground lines, and shielding lines of the analog circuits inside the motherboard PCB are shared, and the signal lines of the analog circuits are soldered to the corresponding interfaces of the board-to-board connectors by the copper foil lines of the PCB.

[0008] Optionally, the board-to-board connector is a male pin connector.

[0009] Optionally, the PCB circuit board is equipped with 8 AI inputs, 8 DI inputs, 11 DO outputs, 11 PWM outputs, 2 CAN_In and CAN_Out buses, 1 power supply and ground.

[0010] Optionally, the CAN communication module is connected to the crane's main controller.

[0011] Optionally, a layer of copper foil is provided inside the housing.

[0012] Optionally, the interface for the AI / DI input signal is provided with a light guide column.

[0013] Optionally, input identification films are affixed to the positions corresponding to the AI / DI input module and the DIHL input module, PWM output identification films are affixed to the positions corresponding to the PWM output signal interface, and DO output identification films are affixed to the positions corresponding to the DO module.

[0014] Optionally, the housing includes an upper housing and a lower housing, which are detachably connected.

[0015] Second aspect: A crane including the integrated branch controller device described in the first aspect.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: (1) High efficiency: The split controller module, which adopts quick connection technology and no wiring process, integrates 4 splitters and 13 plug-in components into one unit. With the help of injection-molded prefabricated cable electrical connection, the total time for the production and assembly of the crane super-lift and counterweight electrical components has been reduced from 20 hours to 0.5 hours, greatly improving the assembly efficiency. (2) Reliability: The electrical system, which uses pre-installed connecting cables and an integrated distribution controller module, has an overall protection level of IP65 or higher. The reliability and consistency of the wiring layout and routing are greatly improved compared with the existing manual construction. (3) Low cost: One existing integrated splitter controller can replace the original assembly of one ordinary controller + four splitters + 13 connectors, as well as the labor cost of manually making wire harnesses.

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] This utility model provides a splitter controller device, including a PCB circuit board. The PCB circuit board includes a PCB main board 7 and a PCB interface board 8. The PCB main board 7 embeds a CPU module, a DOH module, a PWM_CC module, a CAN communication module, and a power supply module. The PCB interface board 8 mainly embeds AI input and DIHL input modules. Communication and power supply between the PCB main board 7 and the PCB interface board 8 are achieved through a board-to-board connector 10. Figure 1 , Figure 2 (As shown).

[0022] The distribution controller device includes: hydraulic signal connectors, angle signal connectors, length signal connectors, tension signal connectors, temperature signal connectors, proximity switch signal connectors, lighting connectors, connectors for multiple solenoid valves, bus signal connectors, and power ground connectors. Each connector pin is connected one-to-one through independent PCB solder pads.

[0023] The AI / DI input signal interface is provided with a light guide post 1, and an input identification film 2 is affixed to the position corresponding to the AI / DI input module and the DIHL input module. A PWM output identification film 3 is affixed to the position corresponding to the PWM output signal interface, and a DO output identification film 4 is affixed to the position corresponding to the DO module.

[0024] The PCB motherboard and PCB interface board communicate and supply power to each other via board-to-board connector 10; they then form the PCB board inside the entire splitter controller. The PCB board is connected to the external housing and connectors to form the entire splitter control device. The PCB board is located inside the housing; the housing includes an upper housing 6 and a lower housing 9, which are detachably connected. The upper housing 6 also has a panel 4 for displaying information.

[0025] PCB interface board 8 externally connects to analog input signals (AI) or digital input signals (DI). Both analog and digital inputs use M12 standard connectors. Internally, the analog circuitry on PCB motherboard 7 shares power, ground, and shielding lines, which are soldered from the internal PCB copper foil traces to the corresponding interfaces of the board-to-board connectors. The analog signal lines are also soldered from copper foil traces to the corresponding ports of the board-to-board connectors, such as 1a, 2a, 3a… The connection method for digital signals is similar, connecting to the corresponding interfaces of the board-to-board connectors, such as 1b, 2b, 3b… The board-to-board connectors are male pin connectors. Figure 3 As shown.

[0026] The external PCB motherboard 7 consists of a 2-pin Dechter pin connector for digital output (DO) and proportional PWM output signals, a 4-pin Dechter pin power connector, and M12 standard pin and socket CAN bus interfaces. The lower PCB board internally houses an AI input module, a DIHL input module, a CPU module, a DO module, a PWM module, a CAN communication module, and a power module. The pins of the power supply, ground, shielding, analog AI module, and digital DI module are connected via copper foil traces to the corresponding interfaces of the board-to-board connectors, such as 1a, 2a, 3a…1b, 2b, 3b…, which correspond one-to-one with the socket female connectors on the PCB interface board 8. Furthermore, the digital output (DO) and proportional PWM outputs are soldered to the corresponding DO and PWM module pins using copper foil traces, respectively. Next, the two CAN bus lines are soldered to the CAN communication module using copper foil traces. Finally, the 4-pin Dechter power supply and ground connectors are soldered to the power module (DC-DC, LDO) using copper foil traces.

[0027] All the modules mentioned above, including the AI ​​input module, DIHL input module, DO module, PWM module, CAN communication module, and power supply module, are connected to the CPU module using copper foil to achieve logic control, data processing, and communication with the external main controller. To improve the PCB board's electromagnetic interference resistance, a layer of copper foil is applied inside the integrated distribution controller housing to effectively isolate the influence of external electromagnetic interference on the module's internal signals. Simultaneously, to improve grounding conductivity, the PCB board's grounding wire and shielding wire are connected to the distribution controller's metal casing for grounding. For example... Figure 4 As shown.

[0028] The splitter controller module has the following features: 8 AI inputs (AI1, AI2, AI3…), 8 DI inputs (DI1, DI2, DI3…), 11 DO outputs (DO1, DO2, DO3…), 11 PWM outputs (PWM1, PWM2, PWM3…), 2 CAN_In and CAN_Out buses, and 1 power supply and ground connection.

[0029] Example 2 discloses a crane, including the line controller device of Example 1; Generally, the input and output signals of the solenoid valves and sensors of the crane's super-lift and displacement counterweight use a portion of the interfaces of this distribution controller, leaving the remaining interfaces unused. To improve the efficiency of this device and prevent the need to replace the entire device due to the damage of a used interface during use, this patent allows connection to the CAN_In or CAN_Out port of the distribution controller via a computer. The unused ports of the same type can be parameterized, and the cable plug of the damaged port can be disconnected and replaced with a configured unused port, restoring operation in the shortest possible time. Alternatively, if the module communicates normally with the main controller and display bus, the damaged interface can be re-parameterized through the display parameterization interface, allowing a similar unused interface to take over the damaged interface. Simply disconnect the cable of the damaged interface and insert the configured interface to restore normal function, greatly extending the module's lifespan (e.g., crane displacement counterweight distribution controller port parameter configuration, see...). Figure 5 In the interfaces of this branch controller, only interfaces of the same type can be used interchangeably through parameterized configuration. For example: AI1, AI2, AI3…AI6, AI7, AI8 can be used interchangeably; DI1, DI2, DI3…DI6, DI7, DI8 can be used interchangeably; DO1, DO2, DO3…DO9, DO10, DO11 can be used interchangeably; PWM1, PWM2, PWM3…PWM9, PWM10, PWM11 can be used interchangeably. Furthermore, AI1, AI2, AI3…AI6, AI7, AI8 can be used as DI1, DI2, DI3…DI6, DI7, DI8; PWM1, PWM2, PWM3…PWM9, PWM10, PWM11 can be used as DO1, DO2, DO3…DO9, DO10, DO11, but the reverse is not possible.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
