Embodiment 1

[0038] The solar brushless motor controller of the present invention is adjusted by adding self-starting settings and corresponding control settings to the solar brushless controller to complete the overall control, especially for applications in Hanoi and long-distance equipment. Brushless motor controllers, improvements and designs on devices that cannot be reached quickly. Figure 7 Among them, the controller and the IoT controller are integrated in a box, and the external pins have antenna transmission interface, power input interface, and brushless motor output interface. The panel is a digital display, displaying battery voltage, power, GPRS signal strength and other information.

[0039] Such as figure 1Shown: The main control circuit of the single-chip microcomputer is the core part of the brushless motor controller. The hall signal, speed signal, over-current detection signal, brake signal, etc. of the motor are directly input to the single-chip microcomputer, which...

Embodiment 2

[0053] Embodiment 2 is basically the same as Embodiment 1, and further includes that the controller also has a current detection function, and the current-limiting and over-current detection signals are sampled in the three groups of MOSFET tube circuits and sent to the single-chip microcomputer. Judging whether the motor is overloaded by detecting the return current of the power MOSFET, if the current is too large, it will input a high voltage to the MCU, then the main control unit of the MCU will cut off the output of the power MOSFET tube, thereby protecting the controller and the motor role.

Embodiment 3

[0055] Embodiment 3 is basically the same as Embodiment 1, and also includes a remote monitoring function. Remote monitoring: This solution is also provided with an Internet of Things terminal. The Internet of Things terminal is a device that connects the sensor network layer and the transmission network layer in the Internet of Things to collect data and send data to the network layer. The Internet of Things terminal is basically composed of three parts: peripheral perception (sensing) interface, central processing module and external communication interface. The data of these sensing devices are read and processed by the central processing module, and then sent to the designated central processing platform of the Ethernet through the external communication interface, such as: GPRS module, Ethernet interface, WIFI, etc., according to the network protocol. In order to better maintain the aerator, this controller also integrates today's Internet of Things equipment into this co...

Abstract

The invention discloses a solar brushless controller, and belongs to the field of solar equipment. The problem that electric equipment powered on by a solar cell panel cannot be self-started and is inconvenient to control in the prior art can be solved. The solar brushless controller comprises a controller shell and an internal control circuit. The control circuit comprises a single-chip microcomputer main control circuit. The single-chip microcomputer main control circuit is used for inputting a hall signal, a rotating speed control signal, a current-limiting over-current detection signal anda brake signal of a brushless motor, and outputting a front-stage driving signal of an electronic commutator so as to control the operation of the brushless motor. A power supply circuit is used foracquiring the electricity of the solar cell panel, carrying out voltage transformation on the acquired electricity and then supplying the power to the controller and the motor. The solar brushless controller further comprises a self-starting circuit. The self-starting circuit controls the starting of the brushless motor. According to the invention, the direct-current brushless motor is driven directly by the direct current generated by utilizing the solar energy without any battery. Meanwhile, the remote monitoring and opening / closing functions are realized by utilizing existing mobile phone signals.

Description

technical field [0001] The invention relates to the field of solar energy equipment, and more specifically, relates to a solar brushless controller. Background technique [0002] The aerators currently on the market are mainly AC 220V / 380V, which need to provide energy for the aeration pump / machine directly through the cable. This power supply method has many inconveniences. For example: energy consumption, cumbersome wiring, poor security and other disadvantages. There are many advantages if the aerator / pump is directly driven by solar panels, but if the aerator / pump is driven by solar energy, a DC brushless controller is required, and the brushless motor controller on the market requires an external signal to start the motor, because the Figure 1 In the main control circuit of the single-chip microcomputer, in the initial stage, the single-chip computer receives the speed control signal, and this signal must be input to the speed signal of 0 ~ 4.5v after the power-on det...
