[0027] The present application proposes an electric forklift starting system, comprising:
[0028] Battery 7, motor 8, vehicle controller 9 and card swiping meter 10;
[0029] The card swiping instrument 10 is used to restrict the use rights of non-registered personnel;
[0030] The key start port of the vehicle controller 9 and the key start port of the card swiping meter 10 are respectively connected to the positive electrode of the battery 7; the positive electrode of the vehicle controller 9 is connected to the positive electrode of the battery 7; the grounding terminal of the vehicle controller 9 and the grounding terminal of the card swiping meter 10 are respectively connected to the negative electrode of the battery 7; the vehicle controller 9 and the card swiping meter 10 are communicatively connected.
[0031] In a possible implementation, the card swiping meter 10 has a built-in radio frequency reader 10 - 1 and a CAN communication module 10 - 2 , wherein the radio frequency reader 10 - 1 is used to identify the identity information of non-registered persons.
[0032] In a possible implementation, it also includes: a one-touch vehicle moving switch 6-2, wherein one end of the one-touch vehicle moving switch 6-2 is connected to the vehicle moving emergency terminal of the vehicle controller 9, and the other end is connected to the positive electrode of the battery 7, which is used to limit the driving speed of the electric forklift after closing.
[0033] In a possible implementation, it further includes: a pre-charging circuit 5, wherein one end of the pre-charging circuit 5 is connected to the positive electrode of the vehicle controller 9, and the other end is connected to the positive electrode of the battery 7, so as to prevent large current shock;
[0034] Specifically, the pre-charging circuit 5 is composed of a diode and a resistor, wherein the positive electrode of the battery 7 is connected to the positive electrode of the diode, the negative electrode of the diode is connected to one end of the resistor, and the other end of the resistor is connected to the positive electrode of the vehicle controller 9.
[0035] In a possible implementation, it also includes: a motor start switch 6-1, wherein one end of the motor start switch 6-1 is connected to the motor start end of the vehicle controller, and the other end is connected to the positive electrode of the battery 7; after the vehicle controller 9 receives the identity authentication pass signal from the card swiping meter 10, the motor start switch 6-1 is closed and the electric forklift is used normally.
[0036] In a possible implementation, the device further includes: an emergency power-off switch 2 and a key switch 3, wherein the emergency power-off switch 2 and the key switch 3 are connected between the key start port of the vehicle controller 9, the key start port of the card swiping meter 10 and the positive electrode of the battery 7, so as to enable the vehicle controller 9 to self-check, the card swiping meter 10 to be powered and ready to perform user identity authentication;
[0037] It can be understood that after the emergency power-off switch 2 and the key switch 3 are closed, the positive pole of the vehicle controller 9 (this positive pole is the positive pole of the power unit inside the controller) is not powered, but the key start port of the vehicle controller (this port is the positive pole of the logic unit inside the controller) is powered, and the internal logic unit of the vehicle controller is powered on to complete the self-test. After the self-test is completed, the internal logic unit of the vehicle controller sends a low-level signal to the contactor coil end, the contactor coil 4-2 is powered on, and the contactor switch 4-1 is closed. At this time, the positive pole of the vehicle controller is powered, and the power unit of the vehicle controller is powered. After the communication unit of the vehicle controller receives the identity authentication pass information from the card swiping instrument end, the motor start switch 6-1 is closed to drive the motor to work.
[0038] In a possible implementation, it also includes: a contactor 4, wherein the two ends of the contactor switch 4-1 are respectively connected to the positive pole of the battery 7 and the positive pole of the vehicle controller 9, and the contactor coil 4-2 is connected to the signal end of the vehicle controller 9 and the end of the key switch 3 away from the positive pole of the battery 7, and is used to control the positive pole of the vehicle controller 9 to be powered after the contactor 4 is closed.
[0039] The present application provides an electric forklift starting system, which restricts the use rights of non-registered personnel, solves the problem that non-professionals can easily use forklifts in violation of regulations, can perform information control on electric forklifts at a low cost and makes it easier and more feasible to trace the use information of forklifts; and in the case where the radio frequency reader is damaged and cannot successfully identify the identity information, the vehicle can be moved with one click, so that the vehicle can be slowly driven away from the unsafe place.
[0040] The present invention is described in more detail below with reference to specific examples:
[0041] See also Figure 1 The electric forklift starting system of the utility model is shown in the figure, which mainly includes a battery 7, a motor 8, a vehicle controller 9 and a card swiping meter 10. The key starting ports of the vehicle controller 9 and the card swiping meter 10 are connected to the positive electrode of the battery through the emergency power off switch 2 and the key switch 3. The resistor 1-1 has the function of protecting the circuit.
[0042] The positive electrode of the vehicle controller 9 is connected to the positive electrode of the battery 7 through the contactor switch 4-1 and the protection resistor 1-2, which has a pre-charging circuit 5 to prevent large current shocks.
[0043] The contactor coil 4-2 of the vehicle controller 9 is connected to the rear end of the key switch 3. The motor start switch 6-1 can control the operation of the motor 8. In order to prevent the card swiping meter 10 from being damaged and affecting the movement of the vehicle, a one-button vehicle movement switch 6-2 is set. By reserving the switch interface in the vehicle wiring harness, the vehicle can travel at a limited speed after closing.
[0044] The card swiping meter 10 has a built-in radio frequency reader 10-1 and a CAN communication module 10-2 in hardware. The radio frequency reader can identify the user's identity information. In this example, the user's identity information is stored in the IC card; Figure 2 As shown, authentication information is added to the instrument display interface where the instrument interacts with the user, and a user setting interface is added to the display interface, which has functions such as "add user", "change user", "delete user", and "user query".
[0045] The specific working process is as follows:
[0046] First, close the emergency power-off switch 2 and the key switch 3. At this time, the key start port of the vehicle controller 9 and the card swiping meter 10 receives the key signal, the vehicle controller 9 enters the self-test state, the card swiping meter 10 is powered, and the meter interface displays the identity authentication prompt. After the radio frequency reader recognizes the user's IC card information, the CAN communication module 10-2 will send a message through the CAN bus, setting the first bit of the first byte as the verification identification bit, 01 indicates verification failure, and 00 indicates verification success. After the vehicle controller 9 receives the 00 message through the CAN bus, the power contactor coil 4-2 is powered, the contactor switch 4-1 is energized, and the positive pole of the vehicle controller 9 is powered. At this time, the motor start switch 6-1 is closed, and the vehicle controller 9 drives the motor 8 to work, realizing the forklift's driving and lifting functions.
[0047] In the case that the RFID reader 10-1 is damaged and cannot successfully identify the identity information, the one-touch vehicle moving switch 6-2 can be closed to energize the power contactor coil 4-2, close the contactor switch 4-1, and energize the vehicle controller 9. However, the vehicle controller 9 will limit the output of the motor's three-phase electricity U / V / W at this time, so that the vehicle can be moved slowly at a limited speed and drive the vehicle away from unsafe places.

However, those skilled in the art should understand that the above implementation examples are only preferred implementation schemes of this application, and the detailed description is only to help readers better understand the spirit of this application, and it is not a limitation on the scope of protection of this application. On the contrary, any improvements or modifications based on the inventive spirit of this application should fall within the scope of protection of this application.
