基于EPS32C3电脑远程开机模块设计

前言

缘起，手头资料太多了，所以想组一台NAS放在家里存储数据。在咸鱼淘了一套J3160主板加机箱，加上几块硬盘组建NAS。

对于NAS，我的需求是不用的时候关机(节省功耗)，要用的时候开机。

网上的开机棒太贵了，也不够安全。

还不如自己制作一个，趁暑假期间(没去实习好亏），刚好手头有一些之前本科毕设用剩下的ESP32C3模块。加上继电器就可以实现远程开机了。

云平台选择腾讯的物联开发平台。无他-因为有ESP32官方例程。

工程修改自乐鑫官方的
Smart Light 使用 ESP32、ESP32S2 配合 腾讯连连小程序 演示了一个智能灯控制方案。

所以这里就不展示其配置过程了，详细内容见Smart Light的README。

接线原理图

IO2–IN

COM–BN

NO–PowerSW

DC±-3V3

DC–GND。

基于EPS32C3电脑远程开机模块接线

代码

short_switch就是短按。短按开机。

long_switch就是长按。长按强制关机。

GPIO初始化

继电器控制的引脚初始化。对于IO2。

esp_err_t lgpio_init()
{//zero-initialize the config structure.gpio_config_t io_conf = {};//disable interruptio_conf.intr_type = GPIO_INTR_DISABLE;//set as output modeio_conf.mode = GPIO_MODE_OUTPUT;//bit mask of the pins that you want to set,e.g.GPIO18/19io_conf.pin_bit_mask = GPIO_OUTPUT_PIN_SEL;//disable pull-down modeio_conf.pull_down_en = 0;//disable pull-up modeio_conf.pull_up_en = 0;//configure GPIO with the given settingsgpio_config(&io_conf);return gpio_set_level(GPIO_OUTPUT_IO_0,1);
}

app_main.c初始化


static esp_err_t example_driver_init(void)
{lightbulb_config_t config = {//1. Select and configure the chip
#ifdef CONFIG_LIGHTBULB_DEMO_DRIVER_SELECT_WS2812.type = DRIVER_WS2812,.driver_conf.ws2812.led_num = CONFIG_WS2812_LED_NUM,.driver_conf.ws2812.ctrl_io = CONFIG_WS2812_LED_GPIO,
#endif
#ifdef CONFIG_LIGHTBULB_DEMO_DRIVER_SELECT_PWM.type = DRIVER_ESP_PWM,.driver_conf.pwm.freq_hz = CONFIG_PWM_FREQ_HZ,

}

控制继电器开闭

简单的控制继电器的操作，通过输出引脚低电平控制继电器闭合。

esp_err_t lightbulb_set_short_switch(bool status)
{esp_err_t err = ESP_OK;LIGHTBULB_MUTEX_TAKE(portMAX_DELAY);s_lb_obj->status.short_on = status;if (status == true){gpio_set_level(GPIO_OUTPUT_IO_0,0);vTaskDelay(1500 / portTICK_RATE_MS);gpio_set_level(GPIO_OUTPUT_IO_0,1);s_lb_obj->status.short_on = !status;}LIGHTBULB_MUTEX_GIVE();return err;
}esp_err_t lightbulb_set_long_switch(bool status)
{esp_err_t err = ESP_OK;LIGHTBULB_MUTEX_TAKE(portMAX_DELAY);s_lb_obj->status.short_on = status;if (status == true){gpio_set_level(GPIO_OUTPUT_IO_0,0);vTaskDelay(15000 / portTICK_RATE_MS);gpio_set_level(GPIO_OUTPUT_IO_0,1);s_lb_obj->status.short_on = !status;}LIGHTBULB_MUTEX_GIVE();return err;
}

获取腾讯云指令按钮的值

bool lightbulb_get_short_switch(void)
{LIGHTBULB_CHECK(s_lb_obj, "not init", return ESP_ERR_INVALID_ARG);LIGHTBULB_MUTEX_TAKE(portMAX_DELAY);bool result = s_lb_obj->status.short_on;LIGHTBULB_MUTEX_GIVE();return result;
}bool lightbulb_get_long_switch(void)
{LIGHTBULB_CHECK(s_lb_obj, "not init", return ESP_ERR_INVALID_ARG);LIGHTBULB_MUTEX_TAKE(portMAX_DELAY);bool result = s_lb_obj->status.long_on;LIGHTBULB_MUTEX_GIVE();return result;
}

任务切换逻辑

  1. 获取腾讯云参数后进入相应的函数。

  2. 设置继电器引脚–控制继电器通。

  3. 设置继电器引脚–控制继电器断。

  4. 更新按钮的状态。

  5. 将值写回参数上传回腾讯云。

后记

没时间折腾，直接更改EPS32的官方例程。

仅仅添加了几行代码实现了想要的工程。

原理很简单，代码写得也很简陋，仅供参考。

等有空了(大概率没空），后续添加电脑状态识别(Power LED+和Power LED-)，接入引脚读取电平。

有闲置电脑的同学可以折腾起来，实现NAS远程开机、电脑远程开机、服务器远程开机。
