Squid

  • The intelligent Wireless Gateway for Smart City and IoT

    The Squid is a central processing unit working as a wireless gateway. Equipped with a powerful ARM9 processor and a Linux kernel, the module monitors various sensors and devices through wireless interfaces. Supporting the leading wireless standards like GSM, WiFi, ZigBee, Wireless M-BUS and Z-wave, makes this a very powerfull gateway/protocol converter. The hardware is running the Amplex OpenCity™ software suite like the Amplex AmsCPU and AmsCPU-IO.

    The Squid serves as a WAN/LAN communications and data concentrator module. Two-way communication with the central server takes place via WiFi, GPRS, SMS or Ethernet. The module has the ability to automatically switch between different available communication carriers in order to provide stable and reliable communication. New carrier types like, e.g. LoRa can be implemented later (using the internal or external USB or the Ethernet port on the module) to obtain the best, most reliable and cheapest communication in the future. Data is either delivered to the server immediately or stored locally in the built-in flash memory of the Squid until scheduled later delivery. Software and configurations are updated remotely from the server and stored on the Squid. Enabling it to autonomously execute tasks. The Squid memory may be expanded using a Micro SD card.

    The Amplex autodiscover mechanism ensures that new devices automatically are discovered and added to the system. Amplex iPhone/Android apps assist the installation team in configuring the discovered devices in the field in very few steps. Making the installation fast and seamless.

    • Communication class availability
      Missing devices
    • The Amplex Communication Framework (AmpCom) enables two-way multi-carrier communication. AmpCom uses communication classes to define the priority of the data. One or more carriers are assigned to each class. If one carrier is not available, another carrier is used instead. Supported carriers: GSM, WiFi, Ethernet (LoRa in process)
    • All modules and meters connected to the Squid are automatically discovered by the system. In case a module/meter is disconnected to the Squid, this is reported to the server application and the module/meter is listed as missing. If the module/meter is reconnected to the Squid or another AmsCPU/Squid, it will be rediscovered by the system.
    • The Squid has a calendar and a real-time clock with an absolute maximum deviation of ±10 seconds per 24 hours in the full temperature range. This is without synchronization with external units. Under normal conditions, clock deviation is automatically adjusted according to the Network Time Protocol (NTP) which gives a maximum deviation of ± 1 second.
    • The collected data are stored in non-volatile memory which holds the values until they are sent to the server. The Squid has the capacity to store data for at least 300,000 historical measurements, depending on the data size of the values.
    • A software management system designed to maintain the software on Squids remotely. Enables installation, removal, and upgrade of software through a web user interface on one or more selected Squids. It also allows on-site upgrades with an authenticated USB memory stick or Micro SD card.
    • Sub system software, e.g. StartGrid™ logic etc. can be downloaded from the Data Centre application for installation and upgrade.
    • From the server application, Squid configuration data can be changed, as required. The configuration data include:
      Communication classes
      Surveillance of communication classes
      MeterMind™ features (an advanced metering infrastructure (AMI) system)
      GreenWise™ features (an advanced power, heat, gas, water benchmarking energy management system)
      StartGrid™ features (a low-voltage power network monitoring and control system)
    • #1: (Green LED) – System status (Booting, ready)
      #2: (Yellow LED) – WiFi status (Scanning, associated, disabled)
      #3: (Red LED) – USB hotplug status (Used for showing status when running a script from a USB dongle)
      #4: (Green LED) – Communication status (Connected/disconnected from the server)
