本篇博文开始讲解下位机插座节点的MCU软件程序是如何实现。
下位机软件架构采用前后台控制系统,使用状态机思维实现程序设计。
开发环境使用Arduino IDE,IDE安装过程可参见:https://handsome-man.blog.csdn.net/article/details/121195905
智能插座的控制器是ESP8266,需要在IDE中安装该开发包,如下图所示:
下位机软件整功能如下图所示:
节点上电后会执行初始化,初始化程序顺序执行,代码如下所示:
- Init_Log();
- Log.verboseln("config start!");
-
- Log.verboseln("init IO");
- Init_IO();
- Log.verboseln("IO OK!");
-
- Log.verboseln("init EEPROM");
- Init_EEPROM();
- if(Device_VariableInitial(MODE1) == STATUS_SUCCESS)
- {
- Log.verboseln("EEPROM OK!");
- }
- else
- {
- Log.errorln("EEPROM ERROR!");
- }
-
- Log.verboseln("init data queue");
- Init_queue();
- Log.verboseln("data queue OK!");
-
- Log.verboseln("init WiFi and server");
- if(Init_WIFI() == STATUS_SUCCESS)
- {
- Log.verboseln("WiFi and server OK!");
- }
- else
- {
- Log.errorln("WiFi and server ERROR!");
- }
-
- Log.verboseln("init time");
- Init_Time();
- Log.verboseln("time OK!");
-
- Log.verboseln("init electrical parameter");
- // Init_BL0942(); // 串口初始化时,已经初始化波特率
- Log.verboseln("electrical parameter OK!");
-
- Log.verboseln("config end!");
-
- program_state.run_state = INIT_STATE;
初始化时候有两点需要注意:
1、节点的日志打印和采集电参数据使用同一路UART,在正式版本软件中,为了避免出现数据错乱的问题,需要将日志打印功能关闭,使#define LOG_OFF 0。
- /**
- ******************************************************************************
- ** \brief 初始化log日志模块
- **
- ** \param 无
- **
- ** \retval 无
- **
- ******************************************************************************/
- void Init_Log(void)
- {
- Serial.begin(4800, SERIAL_8N1); // 4800bps 无校验
- Serial.println();
-
- Log.setPrefix(printPrefix); // set prefix similar to NLog
- Log.setSuffix(printSuffix); // set suffix
- Log.begin(LOG_LEVEL_VERBOSE, &Serial);
- Log.setShowLevel(false); // Do not show loglevel, we will do this in the prefix
-
- #if LOG_OFF
- DeInit_Log();
- #endif
- }
2、E2PROM使用ESP8266内置的Flash模拟。默认情况下,每次线烧程序、OTA升级程序,这部分存储的配置并不会覆盖或者更新,只有上位机下发更新配置参数才会修改。如果想线烧程序更改配置,需要先将标志位#define DEVICE_FLAG 0XAA55修改成非0XAA55的其他数值。
在主循环中使用1ms周期调度维护软件状态机,节点运行有5种状态模式:初始化模式、配置模式、运行模式、重启模式和升级模式。节点默认处于运行模式,代码如下所示:
- switch(program_state.run_state)
- {
- // 初始化模式
- case INIT_STATE:
- Init_State();
-
- break;
-
- // 配置模式
- case CONFIG_STATE:
- Config_State();
-
- break;
-
- // 运行模式
- case RUN_STATE:
- Run_State();
-
- break;
-
- // 重启模式
- case RESET_STATE:
- Reset_State();
-
- break;
-
- // 升级模式
- case UPDATA_STATE:
- Updata_State();
-
- break;
- }
初始化模式中初始化一些变量数据。
初始化模式中,有一个机制,第一次连接立刻上传一次数据到服务器,否则就按照默认的60秒周期上报数据,第一次上报数据会很慢。代码如下所示:
- /**
- ******************************************************************************
- ** \brief 初始化状态逻辑
- **
- ** \param 无
- **
- ** \retval 无
- **
- ******************************************************************************/
- void Init_State(void)
- {
- wifi_send_data.device_head = DeviceParamSave.device_head + FUNCTION_ID1;
- wifi_send_data.device_id = DeviceParamSave.device_id;
- memcpy(&(wifi_send_data.software_version), &(DeviceParamSave.software_version), 15);
- memcpy(&(wifi_send_data.hardware_version), &(DeviceParamSave.hardware_version), 15);
- memcpy(&(wifi_send_data.release_time), &(DeviceParamSave.release_time), 10);
- wifi_send_data.upload_cycle = DeviceParamSave.upload_cycle;
- wifi_send_data.sample_cycle = DeviceParamSave.sample_cycle;
-
- program_state.run_state_time = (DeviceParamSave.upload_cycle * 1000); // 第一次连接立刻上传一次数据到服务器
-
- program_state.run_state = RUN_STATE;
- }
配置模式可接收上位机下发的配置参数,存储到节点E2PROM中。
配置模式有超时机制,3分钟上位机未下发配置参数,自动跳转到运行模式。
更新配置参数后,由配置模式切换到重启模式,节电重启。

只有在运行模式下,上位机才可以切换到配置模式、重启模式和升级模式,其他模式暂不支持远程控制模式切换。
运行模式下可周期上报节点数据,以及支持上位机控制继电器开关。

确保缓存区数据都发送出去并且断开WiFi和服务器连接后节点重启。代码如下所示:

当所有发送缓存区的数据都发送完成后,才可以执行升级功能。
目前升级仅支持局域网升级,升级前节点会发送升级的IP和端口给上位机。

下位机支持日志管理,可自定义串口打印不同等级的日志。
不过打印日志的串口和驱动BL0942的串口共用一路,所以在发布正式程序时,需要屏蔽日志打印功能。

发送和接收数据支持FIFO缓存方式写入和读取数据,可自定义缓存区大小。
本项目中程序基本是顺序结构运行,不存在外部中断和定时任务对数据的干扰,并且发送和接收数据的数据量也不是很大,即使暂不使用FIFO缓存也可以满足使用要求。
数据缓存部分代码如下所示:
- /**
- ******************************************************************************
- ** \brief 初始化数据缓存
- **
- ** \param 无
- **
- ** \retval 无

- ******************************************************************************/
- void Init_queue(void)
- {
- // 清空缓冲区
- memset(send_dataqueue_pool, 0, SEND_DATAQUEUE_POOL_SIZE);
- memset(receive_dataqueue_pool, 0, RECEIVE_DATAQUEUE_POOL_SIZE);
- memset(serial_receive_dataqueue_pool, 0, SERIAL_RECEIVE_DATAQUEUE_POOL_SIZE);
-
- // 静态方式创建一个循环队列,存满不能再存
- tk_queue_init(&send_dataqueue, send_dataqueue_pool, sizeof(send_dataqueue_pool), sizeof(send_dataqueue_pool[0]), false);
- tk_queue_init(&receive_dataqueue, receive_dataqueue_pool, sizeof(receive_dataqueue_pool), sizeof(receive_dataqueue_pool[0]), false);
- tk_queue_init(&serial_receive_dataqueue, serial_receive_dataqueue_pool, sizeof(serial_receive_dataqueue_pool), sizeof(serial_receive_dataqueue_pool[0]), false);
