DGIOT device configuration synchronously sends control commands

[小 迪 导读]：In the process of control equipment,经常会碰到下面这些问题:

Old scheme faults：

• When the platform control instruction without hair down,Platform need to click send control instructions again,The waste of human

dgiotConfiguration synchronization scheme advantages：

• 设备上电,Device status solely by platform administrator control is control values,例如:Platform for shutdown,Field devices even boot platform will automatically be issued shutdown instructions,Turn off the equipment again.

Implementation steps

1.On the platform to create product,如下图为例.

2.In the product details of model created in the equipment to upload"key":"value"The corresponding physical model,如下图为例.

3.Low code is added in the visualization of the product details,如下图为例.

4.Click on the design editor low code,To edit into products low code to add platformkeyAnd upload equipmentkey进行关联,如下图.

Low product code examples,以实际产品为准：
{
  "type": "form",
  "api": {
    "url": "iotapi/classes/Device/parse_objectid",
    "method": "put",
    "headers": {
      "store": "localStorage",
      "dgiotReplace": "parse_objectid"
    },
    "dataType": "json",
    "requestAdaptor": "return {\r\n  \"status\":0,\r\n  \"msg\":\"\",\r\n  \"data\":response\r\n  }"
  },
  "body": [
    {
      "id": "u:52fbc3355570",
      "mode": "inline",
      "name": "Ctrl",
      "type": "switch",
      "label": "开关机",
      "onText": "开",
      "option": "",
      "offText": "关",
      "trueValue": 1,
      "falseValue": 0,
      "validateApi": {
        "url": "iotapi/amis/Product/b5f75b59a3",
        "method": "put",
        "requestAdaptor": "return {\r\n  ...api,\r\n  data:{\r\n    profile:{\r\n      Ctrl:api.data.Ctrl    \r\n      }\r\n  }\r\n}"
      },
      "submitOnChange": true
    }
  ],
  "title": "Switch machine controller",
  "trueValue": true,
  "falseValue": false,
  "submitText": "",
  "optionAtLeft": false
}

5.Find you just created in the visualization of the product details of low code,点击预览,Click add switch machine platformkey,如下图.

6.In the product details found in the physical model of newly created object model,点击编辑,关联平台key与设备key,如下图.

7.Find you just created in the visualization of the product details of low code,点击设计,Modified to equipment low code,如下图.

Equipment low code sample:
{
  "type": "form",
  "api": {
    "url": "iotapi/classes/Device/parse_objectid",
    "method": "put",
    "headers": {
      "store": "localStorage",
      "dgiotReplace": "parse_objectid"
    },
    "dataType": "json",
    "requestAdaptor": "return {\r\n  \"status\":0,\r\n  \"msg\":\"\",\r\n  \"data\":response\r\n  }"
  },
  "body": [
    {
      "id": "u:52fbc3355570",
      "mode": "inline",
      "name": "Ctrl",
      "type": "switch",
      "label": "开关机",
      "onText": "开",
      "option": "",
      "offText": "关",
      "trueValue": 1,
      "falseValue": 0,
      "validateApi": {
        "url": "iotapi/amis/Device/parse_objectid",
        "method": "put",
        "headers": {
          "store": "localStorage",
          "dgiotReplace": "parse_objectid"
        },
        "requestAdaptor": "return {\r\n  ...api,\r\n  data:{\r\n    profile:{\r\n      Ctrl:api.data.Ctrl    \r\n      }\r\n  }\r\n}"
      },
      "submitOnChange": true
    }
  ],
  "title": "Switch machine controller",
  "trueValue": true,
  "falseValue": false,
  "submitText": "",
  "optionAtLeft": false
}

8.设备模拟登录,方式一：MQTTX登录;方式二:ip:18083登录,用户名：admin,密码：public

方式一：MQTTX登录

方式二：ip:18083登录,用户名：admin,密码：public

The user name and password access,如下图：

9.Equipment data simulation report,方式一：MQTTX上报;方式二：ip:18083上报

dgiot上报数据Topic
    $dg/thing/{ProductId}/{DeviceAddr}/properties/report
dgiot下发控制命令Topic
    $dg/device/{ProductId}/{DeviceAddr}/profile

Can the device details to view the correspondingTopic,如下图：

方式一：MQTTX上报

上报数据

Subscribe to the control instruction

方式二：ip:18083上报

上报数据

Subscribe to the control instruction

10.Equipment configuration synchronization to realize,以ip:18083为例

Platform is set to boot,如下图

ip:18083Simulation report status value as0(The state of the shutdown),Platform automatically issued boot command,如下图

Platform is set to off,如下图

ip:18083Simulation report status value as1(The state of the boot),Platform automatically issued the shutdown command,如下图
