Description

Technical Field

[0001] This invention relates to the field of excavator control technology, specifically to a channel lighting control system, method, and excavator thereof. Background Technology

[0002] The cab of a large excavator is located high up, requiring personnel to access it via a passageway. The work areas are often harsh, such as in remote mining areas, where operators endure high physical exertion and may work both day and night. Lighting is particularly crucial at night when getting in and out of the machine; insufficient lighting poses a risk of injury and falls. Currently, large excavators lack dedicated access lighting or have limited lighting functionality. Furthermore, personnel cannot control the lighting from the ground-level entrance; they must first enter the cab and turn on the key and power before controlling the lights. Accidents caused by inadequate lighting at night are frequent.

[0003] Meanwhile, since large excavators may have more than one access road and more than two lighting switches, their lighting requirements are diverse, and the functions of the access road lights are often reused. The traditional double-switch, double-control circuit cannot meet these needs. Therefore, to solve the access road lighting problem for large excavators, an ideal solution is needed. This solution should allow for manual or automatic control of multiple lighting modes for the access road lights at both the outdoor ground entrance and the overhead cab, while conserving energy, thereby improving operational safety. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a channel lighting control system, method, and excavator thereof.

[0005] This invention discloses a channel lighting control system, method, and excavator thereof. The control system drives a time delay relay and a power relay according to a program setting to achieve multiple modes of channel lighting control, so as to meet the lighting needs of users when the channel is moving up and down, solve the lighting problem when the channel is moving up with the key switch off, and realize multiple lighting modes control for large construction machinery when the channel is moving up and down, providing safe lighting for the driver, reducing the risk of falling, while the system is energy-saving and consumption-reducing, and is simple and practical.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A passageway lighting control system includes a battery G, a controller A1, a remote control module A2, a key switch S1, an indoor passageway lighting switch S2, a power relay K1, a power-off delay relay K2, a passageway lighting switch, a passageway lighting relay, and a passageway lighting lamp.

[0014] The channel lighting switch is connected to controller A1;

[0015] The remote control module A2 is connected to the controller A1;

[0016] The control coil of the channel lighting relay is connected to the controller A1, and the switch contacts of the channel lighting relay are connected to the channel lighting lamp.

[0017] The negative terminal of the battery G, the indoor passage lighting switch S2, the controller A1, the remote control module A2, the passage lighting lamp, the control coils of each relay, and the passage lighting switch are grounded.

[0018] Furthermore, the key switch S1, the indoor passage lighting switch S2, and the passage lighting switch are all dual-contact switches.

[0019] Furthermore, the channel lighting switch includes channel I lighting switch S3 and channel II lighting switch S4;

[0020] The channel lighting relays include channel I lighting relay K3 and channel II lighting relay K4;

[0021] The channel lighting includes channel I lighting and channel II lighting.

[0022] Furthermore, one end of the channel I lighting switch S3 is grounded and the other end is connected to the controller A1; one end of the other switch is connected to the positive terminal of the battery G and the other end is connected to the channel I lighting diode V3.

[0023] One end of the channel II lighting switch S4 is grounded and the other end is connected to the controller A1; the other end is connected to the positive terminal of the battery G and the other end is connected to the channel II lighting diode V4.

[0024] One end of the control coil of the channel I lighting relay K3 is grounded, and the other end is connected to the controller A1. One end of its switch is connected to the positive terminal of the storage battery G, and the other end is connected to the channel I lighting lamp.

[0025] One end of the control coil of the Channel II lighting relay K4 is grounded, and the other end is connected to the controller A1. One end of its switch is connected to the positive terminal of the battery G, and the other end is connected to the Channel II lighting.

[0026] Furthermore, the lighting in Channel I includes a bottom lighting lamp E1, a middle lighting lamp E2, and a top lighting lamp E3.

[0027] The lighting for Channel II includes a bottom lighting lamp E4 for Channel II and a top lighting lamp E5 for Channel II.

[0028] The bottom lighting lamp E1, the middle lighting lamp E2, and the top lighting lamp E3 of channel I are connected in parallel to the lighting relay K3 of channel I.

[0029] The bottom light E4 and top light E5 of channel II are connected in parallel to the channel II light relay K4.

[0030] Furthermore, the bottom light E1 of passage I is located at the rear counterweight of the excavator, the middle light E2 of passage I is located at the rear of the lower cab, the upper light E3 of passage I is located at the rear of the cab, the bottom light E4 of passage II is located on the side of the straight ladder, and the top light E5 of passage II is located on the top left of the cab.

[0031] The indoor passage lighting switch S2 is located in the driver's cab, the passage I lighting switch S3 is located at the entrance of the boarding ramp, and the passage II lighting switch S4 is located at the entrance of the elevator.

[0032] Furthermore, a control method for a channel lighting control system includes a channel lighting control method for the outside of the driver's cab and a channel lighting control method for the inside of the driver's cab;

[0033] The method for controlling the lighting of the outer passageway outside the driver's cab is as follows: when the key switch S1 is in the off state, the passageway lighting switch is turned on, the passageway lighting diode controls the power-off delay relay K2 to work, the power diode V1 drives the power relay K1 to work, and the controller A1 is powered on.

[0034] When controller A1 detects the channel lighting switch action signal, it continuously controls the power-off delay relay K2 to work via the power-off delay diode V2, keeping the power relay K1 working to supply power to controller A1. At the same time, controller A1 outputs a signal to drive the channel lighting relay to work and light up the channel lighting.

[0035] If controller A1 does not detect the key switch S1 being turned on after the program-set delay time has elapsed, controller A1 will stop controlling the power-off delay relay K2 to work, thereby stopping the power relay K1 to work, further stopping controller A1 to work, turning off the channel lighting, and the system will enter a low-power saving mode.

[0036] The method for controlling the lighting in the driver's cab passageway:

[0037] When the key switch S1 is in the ON state, the indoor passage lighting switch S2 is turned on. The controller A1 detects the signal that the key switch S1 and the indoor passage lighting switch S2 are turned on. The controller A1 continuously outputs signals to control the power-off delay relay K2 and the passage lighting relay to act, thereby lighting up the passage lighting.

[0038] When the key switch S1 is turned off, the controller A1 continues to maintain the operation of the power-off delay relay K2, which drives the power relay K1 through the power diode V1 to power the controller A1. The controller A1 then controls the channel lighting relay to continue to illuminate the channel lights.

[0039] After the set delay time is reached, controller A1 stops controlling the power-off delay relay K2, power relay K1 stops working, controller A1 is powered off and stops working, the channel lighting is turned off, and the system enters low-power saving mode.

[0040] Furthermore, the control method also includes a remote control method. When the key switch S1 is in the off state, the remote controller sends a command to the remote control module A2. The remote control module A2 drives the power-off delay relay K2 through the remote control diode V5, and drives the power relay K1 through the power diode V1. The controller A1 is powered on and works. At the same time, the remote control module A2 outputs a signal to the controller A1. The controller A1 drives the power-off delay relay K2 to work continuously through the power-off delay diode V2, thereby controlling the power relay K1 to work and supply power to the controller. At the same time, the controller A1 outputs a signal to drive the channel lighting relay to work and light up the channel lighting.

[0041] If controller A1 does not detect the key switch S1 being turned on after the program-set delay time has elapsed, controller A1 will stop controlling the power-off delay relay K2 to work, thereby stopping the power relay K1 to work, further stopping controller A1 to work, turning off the channel lighting, and the system will enter a low-power saving mode.

[0042] Compared with the prior art, the present invention has the following characteristics:

[0043] 1. This invention solves the lighting problem of personnel access passage when the key switch is off. It enables manual or automatic control of multiple lighting modes for passage lighting at the outdoor ground entrance and in the cab of the excavator, thereby improving the safety of work lighting.

[0044] 2. This invention enables multi-mode delayed light-off function when the key switch is off by setting the lighting program, effectively reducing power consumption, and has remote lighting function, further improving the intelligence level of the system lighting.

[0045] 3. The method of the present invention can be used to add more lighting switches and lighting lamps or other lamps as needed, making it convenient to use.

[0046] 4. The method of the present invention, controlled by a controller, can be used for other lighting needs in addition to channel lighting, thus realizing the reuse function of the lamp. Attached Figure Description

[0053] like Figure 2 The diagram shows the structure of the large excavator access lighting control system of the present invention. The access includes stairs and walkways. The stairs include inclined stairs and straight stairs, extending from the underside of the vehicle to the cab for personnel entry and exit; the walkways connect the front, rear, left, and right sides of the vehicle for personnel passage.

[0054] The passageway I consists of a boarding ramp 1 and a vehicle ramp 2, while passageway II consists of a straight ladder 3.

[0055] The bottom light E1 7 of passageway I is located at the rear counterweight of the excavator, providing illumination for the loading ramp 1 in the bottom entrance area of ​​passageway I; the middle light E2 8 of passageway I is located at the rear of the lower cab, providing illumination for the walkway in the middle area of ​​passageway I; the upper light E3 9 of passageway I is located behind the cab, providing illumination for the loading ramp 2 in the upper area of ​​passageway I. The bottom light E4 10 of passageway II is located on the side of the straight ladder 3, providing illumination for the bottom area of ​​passageway II; the top light E5 11 of passageway II is located on the left side of the top of the cab, providing illumination for the top area of ​​passageway II.

[0056] The lighting switches S3 and S4 of passageway I are located at the handrail at the entrance of the boarding ramp 1 and are used for lighting control when personnel are ascending from the ground; the lighting switches S4 and S6 of passageway II are located at the handrail at the entrance of the straight ladder 3 and are used for lighting control when personnel are ascending from the ground; the lighting switches S2 and S5 of the indoor passageway are located at the handrail in the driver's cab and are used for lighting control when personnel are in the driver's cab.

[0057] The present invention relates to a control method for a channel lighting control system, which includes a method for controlling channel lighting outside the driver's cab and a method for controlling channel lighting inside the driver's cab, specifically:

[0058] (1) Control method for lighting in the driver's cab exterior passageway:

[0059] With the key switch S1 off, when personnel ascend from the ground to passage I, pressing the passage I lighting switch S3 at the entrance of passage I for more than one second closes the light switch S3. This closes the light switch S3, causing the passage I lighting diode V3 to activate the power-off delay relay K2, closing its contacts. The power diode V1 then drives the power relay K1, activating its contacts and energizing port 1 of controller A1, thus activating controller A1. Controller A1 port 5 detects the activation signal of the passage I lighting switch S3 and, through port 3, drives the power-off delay relay K2 via the power-off delay diode V2, continuously activating its contacts. This keeps the power relay K1 continuously operating, providing continuous power to controller A1. Simultaneously, port 8 of controller A1 outputs a signal to activate the passage I lighting relay K3, closing its contacts and illuminating the bottom light E1, the middle light E2, and the top light E3 of passage I, thus achieving lighting control of passage I when the key switch S1 is off.

[0060] With the key switch S1 off, when personnel ascend through passageway II from the ground, pressing and holding the passageway II lighting switch S4 at the entrance of passageway II for more than one second closes the light switch S4. This closes the light switch S4, causing the passageway II lighting diode V4 to activate the power-off delay relay K2, closing its contacts. The power diode V1 then activates the power relay K1, closing its contacts, energizing port 1 of controller A1 and enabling controller A1 to operate. Controller A1 port 6 detects the activation signal of the passageway II lighting switch S4 and, through port 3, drives the power-off delay relay K2 via the power-off delay diode V2, continuously activating its contacts. This keeps the power relay K1 continuously operating, providing continuous power to controller A1. Simultaneously, controller A1 port 9 outputs a signal to activate the passageway II lighting relay K4, closing its contacts and illuminating the bottom light E4 and top light E5 of passageway II, thus achieving passageway II lighting control even with the key switch S1 off.

[0061] The control method of this invention also includes a remote control method: When the key switch S1 is off, a person operates the remote control to send a command to the remote control module A2. Port 3 of the remote control module A2 outputs a signal for approximately one second, which drives the power-off delay relay K2 to turn on and close its switch contacts via the remote control diode V5. This, in turn, drives the power relay K1 to turn on and close its switch contacts via the power diode V1, energizing port 1 of the controller A1. Simultaneously, port 2 of the remote control module A2 outputs a signal to port 7 of the controller A1 for approximately one second. Port 3 of the controller A1, via the power-off delay diode V2, continuously keeps the power-off delay relay K2's switch contacts open, thereby controlling the power relay K1 to continuously operate and continuously provide power to the controller A1. At the same time, ports 8 and 9 of the controller A1 output signals to drive the channel I lighting relay K3 and channel II lighting relay K4 to close, illuminating the lighting in each channel, thus realizing remote control of the lighting in channel I and channel II when the key switch is off.

[0062] If the key switch S1 is not detected as on at port 2 of controller A1 after the delay time set in the lighting program is reached, the signal output of port 3 of controller A1 will be stopped, thereby stopping the power supply to power relay K1 and further stopping the power supply to controller A1. Controller A1 will stop working and turn off the lighting in each channel, so that the system enters a low-power saving mode.

[0063] (2) Driver's cab passage lighting control method

[0064] When the key switch S1 is on, and the operator controls the passage lighting from inside the driver's cab, pressing the interior passage lighting switch S2 will cause ports 2 and 4 of controller A1 to detect the on signal of key switch S1 and interior passage lighting switch S2. This will cause ports 3, 8, and 9 of controller A1 to continuously output signals to de-energize delay relay K2 and drive passage I lighting relay K3 and passage II lighting relay K4, thereby illuminating the lights in each passage and realizing the control of passage lighting from inside the driver's cab. Under these conditions, when personnel disconnect the key switch S1 and leave the driver's cab down passage, the controller A1 port 3 maintains the power-off delay relay K2 connected and the switch contact closed. Through the power diode V1, the power relay K1 is driven to connect and the switch contact is closed, continuously supplying power to the controller A1. The controller A1 controls the channel I lighting relay K3 and channel II lighting relay K4 to connect their switch contacts, continuing to illuminate the channel lights. After the set delay time is reached, the controller A1 port 3 stops signal output, thereby stopping the power supply to the power relay K1, further stopping the power supply to the controller A1. The controller A1 stops working, turning off the lights in each channel, satisfying the lighting control requirements when personnel leave, and putting the system into a low-power saving mode.

[0065] According to the control method of the present invention, more lighting switches and lights or other lamps can be added as needed, in addition to channel lighting, to meet more lighting needs and realize the reuse function of lamps.

[0066] The above-described embodiments are merely specific implementations of the present invention, used to illustrate the technical solutions of the present invention, and are not intended to limit it. The scope of protection of the present invention is not limited thereto.
