Description

Technical Field

[0001] The invention relates to the technical field of electric forklifts, and in particular to a forklift control method for continuously cyclically using a forklift. Background Art

[0002] Electric forklifts use batteries (lithium batteries) as their power source. The batteries convert chemical energy into electrical energy to drive the travel motor and hydraulic system motor, thereby achieving travel and loading and unloading operations. There are many types of electric forklifts, including four-way electric forklifts, electric pallet stackers, hand-push electric stackers, electric tractors, etc. Different types of electric forklifts have different characteristics and scopes of application, which can meet the logistics handling needs in different scenarios.

[0003] Electric forklifts are powered by batteries, but during use, the battery has limited power storage. When the battery is out of power, the electric forklift cannot be used. At this time, the staff needs to tow the electric forklift to charge. During the charging process, the electric forklift is in a disconnected state and cannot be put into work, resulting in low efficiency when the company uses electric forklifts. If the number of electric forklifts is increased, not only will the cost investment increase, but too many electric forklifts will also take up space, which is obviously not user-friendly.

[0004] In addition, during use, it often happens that users fail to pay attention to the battery power of the electric forklift in time and overuse the power, causing the battery to over-discharge during use, or sudden power outage. At this time, the goods are left alone and need to be transferred, which brings inconvenience. Summary of the invention

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The illustrations only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0041] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] Example:

[0043] The invention embodiment discloses a forklift control method for continuous cyclic use of a forklift, referring to Figure 1 and Figure 2 As shown, it includes a forklift body 1, a first battery module 2, a second battery module 3, a first backup battery module 4 and a second backup battery module 5. The first battery module 2 and the second battery module 3 are used to provide power to the forklift body 1 in sequence. The battery module mentioned in this application can be a lithium battery in a specific example. The working range of lithium batteries is generally 20%-80% of the power.

[0044] When the control module 6 detects that the power of the first battery module 2 is lower than the lower limit, it switches to the second battery module 3 to supply power to the forklift body 1, and the first battery module 2 warns the user of the first information that charging is required;

[0045] When the control module 6 detects that the power of the second battery module 3 is lower than the lower limit, it switches to the first backup battery module 4 to supply power to the forklift body 1, and the second battery module 3 warns the user of the second information that charging is required;

[0046] When the control module 6 detects that the power of the first backup battery module 4 is lower than the lower limit, it switches to the second backup battery module 5 to supply power to the forklift body 1, and the first backup battery module 4 warns the user of the third information that charging is required;

[0047] When the control module 6 detects that the power of the second backup battery module 5 is lower than the lower limit value and detects that the power of the first battery module 2 is restored, it switches to the first battery module 2 to power the forklift body 1. Otherwise, the second backup battery module 5 warns the user of the fourth information that charging is required.

[0048] In a specific example of the present application, the control module 6 may be a PLC controller, a single-chip microcomputer module or other microprocessors, such as an industrial machine.

[0049] Based on the above scheme, the forklift can be used uninterruptedly through the forklift body 1, the first battery module 2, the second battery module 3, the first backup battery module 4 and the second backup battery module 5, so that the forklift can be used without power outage. As long as one of the batteries is out of power or insufficient, the user can be directly reminded to take out the battery for charging, and the subsequent batteries can continue to be used. Since there are four battery modules, the forklift can be used continuously for a very long time. The user can also put the battery back after charging in time, and then the forklift body 1 can operate very reliably.

[0050] The lower limit value refers to the lower limit value of the battery power, which is considered to be set. It is a parameter pre-set in the control module 6. It is considered to be set according to actual usage. In a specific example, the lower limit value is pre-set to 15% of the battery capacity.

[0051] The first information, second information, third information and fourth information are considered to be set, and are mainly used to prompt the user to charge the battery. In a specific example, the first information is: the first battery is low, charge it in time. The second information is: the second battery is low, charge it in time. The third information is: the first backup battery is low, charge it in time. The fourth information is: the second backup battery is low, charge it in time.

[0052] refer to Figure 1 As shown, the forklift is provided with a battery compartment 7, which is used to store one or more of the first battery module 2, the second battery module 3, the first backup battery module 4, and the second backup battery module 5.

[0055] The first acquisition module 8 acquires the real-time position information of the forklift body 1 itself and the position information of the target unloading area, uses the real-time position information of the forklift body 1 as the current position information of the forklift body 1, and uses the straight-line distance between the current position information of the forklift body 1 and the target unloading area as the current judgment distance.

[0056] The acquisition of real-time location information provides accurate processing guarantee for subsequent interpretation and information processing; it provides reliable data support for data analysis and judgment, and provides a reliable basis for work adjustment.

[0057] The intelligent control module 11 is provided with first transport load information, and the real-time transport load information is acquired by the second acquisition module 10 and used as real-time load information, and the real-time load information is compared with the first transport load information:

[0058] If the real-time load information is less than or equal to the first transport load information, the forklift body 1 moves forward at the first preset power to load the goods;

[0059] If the real-time load information is greater than the first transport load information, the current position information will be obtained to determine the current determination distance; the intelligent control module 11 is also provided with a preset transport distance, and the current determination distance will be compared with the preset transport distance;

[0060] If the current determined distance is less than or equal to the preset transportation distance, unloading is allowed, and the vehicle is controlled to move forward at a second preset power, and the second preset power is greater than the first preset power;

[0061] If the currently determined distance is greater than the preset transportation distance, the vehicle moves forward at a third preset power for unloading, and the third preset power is greater than the second preset power.

[0062] The forklift body 1 is mainly an electric forklift, which is driven by its motor. For the motor drive, its operating power can determine the forward speed and efficiency. Therefore, in this solution, it can be controlled by the discharge power of the battery to achieve intelligent operation.

[0063] Preferably, the first preset power is a low power consumption mode, the second preset power is a medium power consumption mode, and the third preset power is a high power consumption mode.

[0064] Further preferably, a power feedback module for detecting the power supply of the battery is also included, the power feedback module is connected to the intelligent control module 11, the intelligent control module 11 is preset with low power budget power, medium power budget power and high power budget power, and the power feedback module feeds back real-time power information;

[0065] If the real-time power information is less than the high power budget power, the intelligent control module 11 stops the high power mode, switches to the medium power mode, and changes from the third preset power forward to the second preset power forward;

[0066] If the real-time power information is less than the medium power budget, the intelligent control module 11 stops the medium power mode and switches to the low power mode, changing from the second preset power forward to the first preset power forward;

[0067] If the real-time power information is less than the low power budget power, the intelligent control module 11 stops the low power mode and switches to the standby mode, and the forklift body 1 stops moving forward.

[0068] Through the first acquisition module 8, the second acquisition module 10, the intelligent control module 11, etc., it is possible to judge the working condition of the forklift body 1, identify the position, distance, load size, and power supply, make efficient and energy-saving working mode switching, effectively improve the reliability and safety of battery power consumption, optimize the driving working power, and thus improve work efficiency while also having energy consumption control, reducing dependence on manual labor, and reducing the burden of manual operation.

[0069] Further preferably, the value of the low power consumption budget power is greater than or equal to the lower limit value.

[0070] During operation, the battery life is fully considered, which can avoid excessive discharge of the battery and extend the battery life, making the entire forklift cycle more reliable. In the case of power shortage, for example: if the real-time power information is less than the low power budget power, the intelligent control module 11 stops the low power mode and switches to the standby mode, and the forklift body 1 stops moving to avoid excessive discharge, which can provide the control module 6 with sufficient time to switch the backup battery.

[0071] The first acquisition module 8 is provided with a recording unit 81. If the real-time load information is greater than the first transport load information, the current position information of the forklift body 1 is recorded by the recording unit 81 and marked with a first color.
