In this embodiment, the main controller is provided with an upper computer serial port; the three-phase ac motor interface comprises three lines.
In this embodiment, still include the remote control module, remote control module and main control unit electric connection, the remote control module is used for controlling the orchard transport vechicle.
A control method of a modular orchard transporter comprises the following steps:
the memory chip and the security authentication chip share an interface with the main controller. When the main controller program is started, before a control instruction is sent to the three-phase alternating current motor every time, the ID number of the controller is read, authentication is initiated to the safety authentication chip, if the authentication is passed, the motor control instruction is normally executed, otherwise, a motor control signal is not sent.
The memory chip is used for storing the equipment setting and state information when the equipment is powered down, and the information mainly comprises the position information of a transport vehicle, the real-time voltage and power of a three-phase motor and the like.
The main controller detects the state of the three-phase alternating current motor in real time through the detection module, and cuts off the power supply of the motor in time when the output power exceeds a threshold value or is lower than the threshold value, and switches the program of the controller to a shutdown state.
The input signals include stop (S), advance (F) and retreat (B). Three-phase alternating current motor interface U, V and three W wires, two wire connection methods are exchanged arbitrarily, and the three-phase alternating current motor is reversed. Assuming that the forward and reverse rotation of the motor is realized by exchanging the U and V lines, a UV signal is logically output to indicate the forward rotation of the three-phase alternating current motor, and a VU signal is output to indicate the reverse rotation of the motor. The phase sequence logic control block diagram of the three-phase motor is shown in fig. 2.
U, V and W in FIG. 3 are three phase lines of three-phase AC, respectively, and M1, M2 and M3 are power output ports of the three-phase motor. When the program runs off, any input control signal from the CPU cannot short the U and V lines under the protection of the logic circuit. The output ends of the thyristors (Q1-Q5) in the figure 3 inhibit stronger electromagnetic interference generated when the thyristors are switched on and off through a resistance-capacitance filter circuit.
The main controller is connected with the remote control module. And connecting the finished remote control receiving module with the control panel in a welding or inserting mode. DirTog is a phase sequence switch, and when the phase sequence of random access is opposite to the direction on the vehicle and the direction on the remote controller, the switch is switched to realize the switching of the positive direction. The Program is a programming interface, and the Program is upgraded through the interface when the Program needs to be upgraded.
The memory chip and the safety chip interface circuit are consistent in peripheral interface and are distinguished through an address pin A0. The storage chip realizes power-down storage, but if the main controller can realize power-down storage by Flash, the chip is not needed. The security chip is used for encrypting the software system and welding as required.
The travel switch input interface keeps the original 24V to keep the original better anti-interference capability. The voltage and the current of the input signal are limited through the circuit so as to protect the main controller.
The AC220V changes DC24V and DC5V circuits, and corresponding voltages are provided for all parts of the system. And the onboard power supply module replaces an independent power adapter, so that the system integration level can be improved.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
