Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of battery exchange cabinet intelligent control, specifically relates to a kind of battery exchange cabinet control panel with multiple path storehouse lock control and motor control simultaneously. BACKGROUND

[0002] Intelligent battery exchange cabinet is the quick battery supplementing facility designed to solve the endurance problem of two-wheel and three-wheel electric vehicles, and provides convenient battery replacement service for users by distributing in multiple points in city.The battery exchange cabinet control panel, as the core control system of cabinet, is responsible for managing the operation logic of the entire battery exchange cabinet, including battery storage and access, state monitoring and safety guarantee.

[0003] To prevent battery theft or misappropriation by users during battery exchange, the prior art mainly uses the following two battery anti-loss schemes, which both need the participation of battery exchange cabinet control panel in control.

[0004] Scheme one (storehouse door lock dependent type): after the user puts the battery into the bin, manually closes the storehouse door lock.The battery exchange cabinet control panel determines whether the battery is physically locked in the bin by detecting the lock state signal of the storehouse door lock, thereby realizing the anti-theft function.The scheme mainly relies on the user's manual operation of physical lock, and the control panel plays a role in state monitoring.

[0005] Scheme two (motor-driven locking type): a separate motor-driven locking mechanism is provided in the bin, and the battery to be exchanged is usually designed with a corresponding slot structure.After the user puts the battery in, the battery exchange cabinet control panel outputs a control signal to a separate motor drive circuit board, which drives the motor to act, so that the locking mechanism engages with the battery slot to actively lock the battery in the bin, thereby playing a role in battery theft prevention.

[0006] Both of the above schemes can realize the basic battery anti-theft function.However, in terms of implementation, especially scheme two, a separate motor drive circuit board is needed to respond to the instructions of the control panel and drive the motor to act.The design of separating control logic (battery exchange cabinet control panel) and execution drive (motor drive circuit board) on different circuit boards is low in integration, low in space utilization.When a battery needs both storehouse door lock and motor-driven lock, multiple circuit boards must be used for control, which may have the following potential problems: relatively complex circuit structure, multiple board card redundancy, more components, higher overall cost, larger space occupation, and may increase the risk of connection point failure.

[0029] Example 2

[0030] Preferably, the MCU control unit 2 is connected with the warehouse door lock drive unit 4 through the GPIO single bus for control, and the warehouse door lock drive unit 4 feeds back the state of the current warehouse door lock 11 to the MCU control unit 2 through the GPIO single bus; the MCU control unit 2 is communicatively connected with the interface extension unit 3 through the address bus, and the interface extension unit 3 is communicatively connected with the π type filter 9 through the GPIO pin.

[0031] As Figure 3As shown, preferably, the SOC control unit 1 is an ARM controller chip, specifically an RK3568 chip, the MCU control unit 2 is a single chip microcomputer, specifically an STM32F407, and the interface expansion unit 3 is a D-type latch. The door lock drive unit 4 includes a transistor + MOS tube drive circuit.

[0032] The SOC control unit 1 and the MCU control unit 2 communicate with each other through the CAN communication bus 8, and the physical connection method is the line connection on the PCB board; the MCU control unit 2 is connected and controlled with the warehouse door lock drive unit 4 through the GPIO single bus, and the warehouse door lock drive unit 4 feedbacks the current warehouse door lock 11 status to the MCU control unit 2 through the GPIO single bus; the MCU control unit 2 is connected with the interface expansion unit 3 through the address bus, and then the interface expansion unit 3 communicates with the motor drive unit 5 through the GPIO pin to control the extension and retraction of the motor.

[0033] The main function of the SOC control unit 1 is to run the upper-level control software of the battery exchange cabinet system and decide the action timing of the door opening and closing motor; the main function of the MCU control unit 2 is to receive the logic instructions issued by the upper-level SOC logic control unit, and parse and generate device drive signals; the interface expansion unit 3 is used to increase the number of GPIO pins of the MCU control unit 2 and improve the driving capability of the GPIO pins; the main function of the door lock drive unit 4 is to directly drive the door lock and feedback the lock status to the MCU control unit 2; the main function of the motor drive unit 5 is to directly control the extension / retraction of the locking motor.

[0034] Example 3

[0035] like Figure 2 As shown, both the door lock drive unit 4 and the motor drive unit 5 have 6 channels. Compared with the traditional separate design, the present invention achieves the following effects:
