Description

Technical Field

[0001] This invention relates to the field of robotics, and more specifically to an emergency start-up method for an engineering robot. Background Technology

[0002] Wireless remote-controlled engineering robots are equipment capable of performing tasks such as digging, crushing, and gripping from a distance in dangerous environments that threaten human lives, by quickly changing various working devices. This equipment can also be used for emergency rescue operations in confined spaces, such as tunnel rescue and underground engineering collapse rescue.

[0003] Engineering robots operate in complex environments, and to meet practical needs, they are equipped with both remote and short-range (redundant) remote control systems. The complex and harsh working environment of engineering robots causes significant interference with remote control signal transmission. Despite the redundant remote control system, there are still situations where both remote and short-range remote control signals fail completely, or the onboard controller malfunctions. Due to remote control failure, the engine cannot start, the entire robot cannot move, and in an emergency, it cannot be moved in time, posing a significant safety risk. Summary of the Invention

[0004] To address the aforementioned problems, this invention aims to provide an emergency starting method for engineering robots. This method involves equipping the vehicle with an emergency power-on switch and an emergency start switch. The former powers the vehicle, while the latter starts the engine. When the remote control signal fails or the controller cannot send a command to close the relay, the closing of the power-on and start switches replaces the command transmission. This allows for manual operation to replicate the normal controller signal transmission process, enabling the emergency starting of the engineering robot, timely robot transfer, and reduced safety risks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An emergency start method for an engineering robot includes an engine ECU, a high-current electrical box, a starter motor, an emergency start switch, an emergency power switch, a battery pack, a smart fuse box, an on-board controller, and a remote controller. The high-current electrical box includes a main power relay and a starter relay. The system starting method composed of the above modules is divided into regular start and emergency start.

[0007] The conventional starting process involves controlling the vehicle's power-on and starting via a remote control.

[0008] The conventional starting method steps are as follows:

[0009] Step 1: The remote control transmits the power-on signal to the vehicle-mounted controller via wireless communication;

[0010] Step 2: The vehicle-mounted controller sends a signal to connect the main power relay, thereby energizing the smart fuse box 20B and completing the power-on of the entire vehicle;

[0011] Step 3: After the vehicle is powered on, the on-board controller controls the smart fuse box to supply power to the engine ECU via the CAN bus;

[0012] Step 4: After the engine ECU is powered on, it turns ON and sends a signal to activate the starter relay, which powers on the starter motor and makes it work, thus completing the engine start-up.

[0013] The emergency start refers to manually activating the emergency power-on switch and the emergency start switch to power on and start the vehicle after the remote control fails.

[0014] The emergency start method steps are as follows:

[0015] Manually close the emergency power switch to supply power to the engine ECU and activate the main power relay;

[0016] Step 2: After the main power relay is turned on, power is supplied to the 20B terminal of the smart fuse box to power on the entire vehicle;

[0017] Step 3: After the vehicle is powered on, close the emergency start switch to turn the engine ECU to the ON position, which will also activate the starter relay, powering on the starter motor and enabling it to start the engine.

[0018] The remote control is a separate structure from the vehicle and transmits the power-on signal to the vehicle-mounted controller wirelessly.

[0019] The vehicle-mounted controller, engine ECU, and high-current electrical box are arranged vertically from low to high.

[0020] The smart fuse box and the vehicle-mounted controller are placed horizontally on the same plane, with the smart fuse box located to the right of the vehicle-mounted controller.

[0021] The battery pack is located at the lower right of the smart fuse box.

[0022] The emergency power-on switch and emergency start switch are arranged in order from bottom to top on the top of the smart fuse box.

[0023] The starter motor is located to the upper left of the emergency power-on switch and the emergency start switch, and to the right of the high-current electrical box.

[0024] Compared with the prior art, the present invention has the following advantages: an emergency power-on switch and an emergency start switch are configured at the vehicle end. When the remote control signal fails or the controller cannot send a command to close the relay, the emergency power-on switch and the emergency start switch are closed by manual operation. In this way, the command is sent to realize the controller signal transmission process under normal circumstances and complete the emergency start of the engineering robot.

[0031] The conventional starting process involves controlling the vehicle's power-on and starting via a remote control.

[0032] The conventional starting method steps are as follows:

[0033] Step 1: The remote controller 9 wirelessly transmits the power-on signal to the vehicle-mounted controller 8;

[0034] Step 2: The vehicle-mounted controller 8 sends a signal to connect the main power relay 21, thereby energizing the smart fuse box 720B and completing the vehicle power-on process; Figure 2 (The part with the solid red line in the middle)

[0035] Step 3: After the vehicle is powered on, the on-board controller 8 controls the smart fuse box 7 to supply power to the engine ECU1 via the CAN bus;

[0036] Step 4: After the engine ECU1 is powered on, it switches to the ON position and sends a signal to activate the starter relay 22, which powers the starter motor 3 and enables it to start, thus completing the engine start-up process. Figure 2 (The part with the solid blue line)

[0037] The emergency start is achieved by manually activating the emergency power-on switch 5 and the emergency start switch 4 after the remote control fails, thus powering on and starting the vehicle.

[0038] The emergency start method steps are as follows:

[0039] Step 1: Manually close the emergency power switch 5 to supply power to the engine ECU1 and turn on the main power relay 21;

[0040] Step Two: After the main power relay is turned on, power is supplied to the 720B terminal of the smart fuse box to power on the entire vehicle. Figure 2 (The red dotted line in the middle)

[0041] Step 3: After the vehicle is powered on, close the emergency start switch 4 to turn the engine ECU1 to the ON position, which in turn activates the starter relay 22, powering on the starter motor 3 and enabling it to start, thus completing the engine start-up process. Figure 2 (The middle blue dotted line area)

[0042] The remote controller 9 is a separate structure from the vehicle and transmits the power-on signal to the vehicle-mounted controller 8 wirelessly.

[0043] The vehicle-mounted controller 8, engine ECU 1, and high-current electrical box 2 are arranged vertically from low to high.

[0044] The smart fuse box 7 and the vehicle-mounted controller 8 are placed horizontally on the same plane, with the smart fuse box located to the right of the vehicle-mounted controller 8.

[0045] The battery pack 6 is located at the lower right of the smart fuse box 7.

[0046] The emergency power-on switch 5 and the emergency start switch 4 are arranged from bottom to top directly above the smart fuse box 7.

[0047] The starter motor 3 is located to the upper left of the emergency power-on switch 5 and the emergency start switch 4, and to the right of the high-current electrical box.
