The first line of defense against tampering by bypassing current, reversing connections, and disconnecting leads is the meter case. Due to this, it is common for utilities to require some form of intrusion detection system to detect when someone opens a case. In this section, we will cover how to detect someone trying to open the case of a meter.
For anti-tampering, it is common to try to detect the presence of a strong magnet. In this section, we will cover the use of hall sensors for low-power detection of strong magnetic fields in three dimensions. Details on our magnetic tamper detection reference design, TIDA-00839, will be provided as well as some of the design considerations that were kept in mind when creating this reference design.
In this section, we will cover how to harden a meter against these magnetic tamper attacks by using shunts for current sensors. For poly-phase implementations, I will go over how to use isolated delta sigma modulators to add the necessary isolation to use shunt current sensors and create magnetically immune poly-phase energy measurement systems. The TIDA-00601 and TIDA-01094 reference designs, which show how to implement a poly-phase isolated shunt measurement system, will be discussed as well as the associated AMC1304 high-side power supplies used in these designs.
In this section, a summary of the entire “Anti-tamper Techniques to Thwart Attacks on Smart Meters” training module would be covered. This summary would cover the “Detecting case tamper attacks using inductive switches “, “Detecting magnetic tampering using hall-effect sensors “, and “Hardening a meter against magnetic tamper attacks “ sections of the training series. Links will be provided for the reference designs and design tools that were discussed during this training series.
The purpose of this course is to review basic electronic components and the electrical properties needed to interface sensors and actuators to a microcontroller. You will learn how to measure reactance of a capacitor and use your project to measure current and voltage. The electrical properties of the capacitor will help you design circuits that “filter” or remove noise from your robot.
This module serves as a brief introduction to the ARM Cortex-M microcontroller, assembly programming language and some debugging techniques. Understanding how the processor works is essential for the design of embedded systems, such as the one used in your robot.
This module is an introduction to C, a general-purpose programming language, in addition to the concepts of compiling and debugging using the MSP432 and TI Code Composer Studio™. Debugging skills are a valuable tool when developing complex systems involved with robotics.
In this module, you will create the robot. You will then be able to measure the voltage, current and energy for a battery while managing voltage regulation. This will allow you to build the circuits needed to power the robot.
In this module, you will interface a line sensor (infra-red sensor) to the microcontroller and learn how to write software to initialize GPIO pins. The line sensor is a simple and accurate sensor for solving robotic challenges.
The purpose of this module is to develop interface switches and an LED so the robot can effectively detect wall collisions. Many sensors and actuators deploy LEDs, so understanding how they operate will be important to building your robot.
This module provides an intro to how flash memory operates, including debugging techniques for real-time systems and how to generate periodic interrupts using SysTick. Minimally intrusive debugging is essential for real-time systems to evaluate performance while the system runs in real-life situations.
This module will show you how to display characters and provide real-time debugging on a display screen. An LCD or OLED on your robot provides a convenient way to observe what it is thinking.
