  Tested by: Beijing Great Wall measurement and Testing Technology Research Institute of China Aviation Industry Corporation (the first measurement and testing research center of national defense science, technology and industry)

  Manufacturer: Beijing Juying soaring Electronics Co., Ltd

  Instrument name: remote measurement and control terminal (RTU)

  Model / specification: RTU

  one

  Reduce room temperature to low temperature (from 25.0 ℃ to - 40.0 ℃)

  Put the bare metal of remote side control terminal into the climate test chamber Power on the test chamber The temperature of the test chamber shows 26.0 ℃ Set temperature point - 40.0 ℃ Start the climate test chamber It began to cool down

  Normal communication

  The data is normal

  two Low temperature storage (40.0 ℃) The temperature of the test chamber reaches 40.0 ℃ and is maintained for 60min after equilibrium.

  Normal communication

  The data is normal

  three

  Cooling (from - 40.0 ℃ to - 45 ℃)

  Set temperature point - 45.0 ℃ It began to cool down Cool to 45.0 ℃

  Normal communication

  The data is normal

  four

  Upper performance inspection side (- 45 ℃)

  After the temperature of the test chamber reaches - 45.0 ℃, it shall be kept for 4H In the insulation stage, the remote measurement and control terminal is always powered on and communicated

  Normal communication

  The data is normal

  five

  Low temperature start-up reconnection performance test (I 45 ℃)

  Power off the device Keep the temperature at 45.0 ℃ for 30 minutes Turn on the power supply of the tested equipment and monitor the network connection and data return

  Normal start

  Normal communication

  The data is normal

  six

  Temperature rise (from 45.0 ℃ to 85.0 ℃)

  Set the temperature point at 85 ℃, 95.0% RH Start heating up to 85.0 ℃

  Normal communication

  The data is normal

  seven

  Working performance test (85.0 ℃, 95.0% RH)

  The temperature of the test chamber reaches 85.0'c, 95 Keep it for 3h after o% RH balance. heat preservation

  At this stage, the remote state control terminal has been powered on and communicated

  Normal communication

  The data is normal

  eight High temperature startup reconnection performance test (85. O ℃. 95. O% RH) Power off the device Keep the temperature at 85 OC, after 30 minutes of balancing, turn on

  Turn on the power supply of the tested equipment Monitor networking and data return Normal start

  Normal communication

  The data is normal
