Infrared Module

Description

Infrared Module是基于红外上进行二次开发的无线设备，由STM8L151G4U(控制器)、CC1101(无线模块433M)等组成，使用外部12V电源供电，主要实现安防监控(需要与安防控制盒进行配对)，整体体积15 * 30* 5 mm。

Hardware

  • 控制器　 : STM8L151G4U6
  • 无线芯片 : CC1101
  • 外接介面 : 1 x KEY
  • PCB 尺寸 : 15 x 30 x 1 mm
  • 設計軟體 : Altium Designer 09

Software

该设备采用433M通信频率，无线芯片采用CC1101。考虑到电池使用寿命及报警器的工作特点，传感器类终端设备采用单向通信，发送数据只有一种帧结构，包含报警、电池欠压和设备状态信息。帧格式如下所示：

同步码 帧长度 控制码 产品序列号 模式
8799 08 00 301234567890 00/F0/08

该设备与安防控制盒工作流程：

  1. 该设备发向后台的信息，安防控制盒按照信息的含义完成相应的功能，并且都可作为心跳，表示终端在线

  2. 该设备发生报警需要连续发送二次报警信息给安防控制盒，两次发送数据间隔随机200-500毫秒

  3. 该设备报警发送F0，安防控制盒向后台发送告警信息，并提示有人闯入。

  4. 该设备空闲超过3小时(即心跳)需要发送工作状态安防控制盒

  5. 该设备空闲超过12小时(即电压检测)，一天检测两次，即每4次心跳，需检测，如果电池欠压则需叠加电池欠压信息(08)发送工作状态安防控制盒

  6. 该设备需在第一次上电时需检测电量，每次报警被触发时，不带欠压告警

  7. 该设备需在特定Flash地址写入12位序列号，每个设备的序列号不能重号
