Description

Technical Field

[0001] The utility model relates to the technical field of manpower transport vehicles, in particular to a CAN communication handle for a manpower transport vehicle. Background Art

[0002] Manual transport trucks are common equipment in the industrial and logistics sectors, primarily used for transporting and transferring heavy objects. However, existing manual transport trucks typically utilize traditional mechanical handles for control. This handle design often requires a single handle to simultaneously control multiple actuators. However, since each actuator has its own independent control module and fault alarm system, this design presents significant drawbacks.

[0003] First, when multiple actuators are operating simultaneously, fault alarms are determined independently for each actuator. If one actuator is operating normally while another fails and stops working, the operator will not be able to immediately receive synchronized alarm information. This means that at some point, the alarm information from different actuators may be out of sync. This requires the operator to check the status of each actuator separately, greatly increasing the complexity and inconvenience of operations and also affecting work efficiency.

[0004] Secondly, the sudden stoppage of individual actuators can negatively impact the coordination and reliability of the entire system. A single handle prevents centralized fault diagnosis and unified handling, leading not only to operational confusion but also potentially serious safety hazards. For example, if an actuator on a transport truck suddenly stops while in operation without a timely and synchronized alarm, it could cause load imbalance or damage the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a CAN communication handle for a man-powered transport vehicle, which can effectively improve the convenience of transport vehicle operation and system reliability, ensure the coordinated operation between various actuators, synchronize alarm information in a timely manner, reduce troubleshooting time, optimize the overall transport operation, and improve the safety and efficiency of the equipment.

The advance and retreat toggle switch and the interlock signal switch are connected to the CAN communication handle mainboard via wires, and the interlock button assembly can trigger the on and off of the interlock signal switch by pressing; the handle front guard plate and the handle rear guard plate are fastened and fixed by a double combination of cross machine screws; the maintenance cover plate is fastened to the back of the handle rear guard plate by a cross countersunk flat tail self-tapping screw.

[0008] Preferably, the A motor controller provides power to the CAN communication handle, and the A motor controller independently controls the A actuator.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 3 As shown, the present invention proposes a CAN communication handle for a manpower transport vehicle, wherein the handle body is used for holding and operating by the user; the handle body has a CAN bus interface for sending and receiving control signals via the CAN bus; and a microprocessor for processing user input and generating corresponding control instructions, while performing fault judgment and alarm synchronization; and also includes a power supply module for providing power to the handle and its internal components, such as Figure 2 As shown, power modules B+ and B- provide power for the entire system.

[0022] The CAN communication handle 1 communicates with the A motor controller 2 and the B motor controller 3 through the CAN network composed of CANH and CANL. The A motor controller 2 provides a DC+14V power supply to the CAN communication handle 1, which is used for the internal power supply of the CAN communication handle 1 and the switch signal of the interlock signal switch 8. The A motor controller 2 controls the A actuator 4 independently, and the B motor controller 3 controls the B actuator 5 independently. Both the A actuator and the B actuator are motors. The overall system topology schematic diagram is shown in the figure. Figure 2 .

[0023] The structure of the CAN communication handle 1 is as follows Figure 1 As shown, the forward and backward toggle switch 7 and the interlock signal switch 8 are connected to the CAN communication handle mainboard 6 through wires, and the interlock button assembly 9 can trigger the on and off of the interlock signal switch 8 by pressing; the handle front guard plate 10 and the handle rear guard plate 11 are fastened by double combination cross machine screws 12; the maintenance cover plate 13 is fastened to the back of the handle rear guard plate 11 by cross countersunk flat tail self-tapping screws 14. After removing the maintenance cover plate 13, the CAN communication handle mainboard 6 can be maintained and upgraded.

[0024] The topology diagram of the CAN communication handle is as follows Figure 3 As shown, after the CAN communication handle mainboard 6 receives the DC+14V power supply from the A motor controller 2, it is converted into DC+5V by the internal power conversion module to power the forward and backward dial switch 7. The CAN communication handle mainboard 6 collects the signal of the forward and backward dial switch 7 and the switch signal of the interlock signal switch 8 and processes them into CAN signals and broadcasts them to the CAN bus. At the same time, the CAN communication handle mainboard 6 receives messages from other nodes on the bus in real time through the CAN bus.

[0025] Working principle: When any one of the A motor controller 2 and B motor controller 3 reports a fault code, it is broadcasted to the CAN bus. The CAN communication handle mainboard 6 recognizes the fault on the CAN bus and resets the signal of the forward and backward toggle switch 7. This implements the logic that when a single node controller fails, multiple node controllers stop at the same time, ensuring safety during use.
