Water and heat meters share multiple system building blocks, such as the metrology sub-system and the application sub-systems, the Wireless communications part, the InfraRed optical port or the power solution. In this section, we will cover a new ultra-low cost single-chip LC-sensing solution utilizing the CC1350 Wireless MCU and its Sensor Controller Engine. Two external LC-tanks with a TI FemtoFET device each implement two rotation detection sensors, which measure the rotation of a half-metal/half-nonmetal disc, often used in mechanical water meters.
Some EU standards like EN1434-3 for heat meters require optical interface as per EN62056-21, where two separate IR LEDs are used (one for receive and one for transmit direction). TIDA-01212 shows an alternative approach, which uses a single IR LED to implement a bi-directional IrDA PHY link with 9.6 kbps in half-duplex mode. The design approach can the system reduce cost of any smart (sub-)metering device by replacing the legacy optical IrDA PHY modules with two separate LEDs.
This module covers the “Innovative 7-Segment LCD Control Using GPIO Pins and SW” section of the “Single-chip Smart Water meter with Dual-band RF link and InfraRed port” training series.
This introduction video will give the background on FPD-Link III devices, such as the DS90UB953-Q1/ DS90UB954-Q1; the device's role within Advanced Driver Assist Systems (ADAS) in the automotive industry; and explain their broad appeal to engineers of all experience levels. This is fundamental to diving deeper into a 953/954 system, as well as, the links within the system.
This section frames the design and operation video series by showing why it is important to contextualize customer problems in terms of the links between the devices.
Specifically, this section will discuss: issues with initializing the camera and issues with reading the incorrect serializer ID from the deserializer.
Understanding what hardware and software settings are important is critical to establishing a foundation for the 953/954 system. These settings can occur during or after power up and may need to be changed via software. As a result, these settings are routinely checked and verified before checking any of the other links in the system.
Specifically, this sections discusses: Diagnostics post power up, Mode and IDX Pins, Clocking Modes between the 953/954, Aliasing, I2C Pass Through, Port selection on 954, Analog Launch Pad (ALP), and Successful I2C Communication
This section analyzes the link between the 953 and 954 and establishes how to identify the health and operation of the link. Since the link between the 953-954 is the most fundamental link used to communicate between devices, it is often checked first.
Specifically, this section discusses: Back Channel configuration, Built in Self Test (BIST), Adaptive Equalization (AEQ), and Channel Monitor Loop (CMLOUT)
This section discusses what frame synchronization (FrameSync) is and how to configure in on the 953 and 954 and how CSI2 data is transferred across the link from the 954 to the ISP/SoC
Specifically, this section discusses: Frame Synchronization (FrameSync), Controlling 953 GPIOs locally and remotely via I2C, Unsynchronized and synchronized sensors, Internal and External Frame Sync, Port Forwarding, Accessing Indirect Registers, and Pattern Generation on 953 & 954
This section discusses how design a 953/954 using Power over Coax (PoC), and various hardware checks and concepts that need to be considered when analyzing a 953/954 system.
Specifically, this section discusses: Power Over Coax (PoC), AC Coupling Capacitors, PoC Inductors, Typical PoC Schematic, Critical Signal Routing, I2C Pullups, Loop Filter Capacitors on 953, Insertion Loss, Return Loss, and Time Domain Reflection (TDR) measurements.
In 2019 more than 2.5 million industrial robots will be in operation worldwide, according to a forecast of the international federation of robotics. An industrial robot typically consists out of a control cabinet, a robot arm and a Human Machine Interface (HMI) Panel. To guarantee safe operation of the complete robot system, the different robot components and its interfaces need to be isolated to each other.
The training starts with an overview of an analog input module. Typical components and their voltage supply levels are shown. Next, possible power topologies like push-pull, flyback or flybuck with their advantages and disadvantages are discussed.
CNC routers use step and direction signals to control each stepper motors. In addition motor information (position, temperature, fault) gets transferred from stepper motors back to control unit. This must be done in star topology and a mix of proprietary interfaces. Simple open real-time Ethernet (SORTE) enables 4 µs cycle time on industrial Ethernet and replaces step/direction signal and motor feedback info into a single Ethernet cable that is also wired in line topology.
A common method to measure process parameters in plants is based on sound waves. This method is used in: level, flow and displacement field transmitters. It works based on measuring the time of flight (ToF) between when the pulse, generated by a piezo electric crystal, is sent and received back by the piezo.
This training helps to understand relevant parameter of a 4-20mA analog input module, such as surge protection, handling miss-wiring, broken wire detection, isolation or protection of the module against over-current at power and signal inputs.
Analog outputs in industrial automation come in a variety of configurations that each must deliver strong precision while passing stringent EMI /EMC certification tests. This session will address these systems and their challenges by explaining each configuration, and explaining example designs
Before we dive into specific application-based examples of noise and EMI mitigation, let's start with the basics. What is noise? What is EMI? What is ripple? How are they measured? What are some common approaches to limiting their effects? This section discusses these topics with a more conceptual approach to serve as a primer for the rest of the series.
Now that we understand the sources of EMI and noise in switching regulators, and some of the common approaches to mitigating each, let's take a closer look at real-world examples of reducing their effects. In this section we will examine the impacts of various mitigation techniques to help you decide which approach makes the most sense in your design. Techniques covered in this discussion include external component placement, filter options and design, frequency manipulation via spread spectrum or dithering, snubbers, boot resistors, and more.
