After the long-term deployment of smart meters (automatic meter reading infrastructure), a two-way back and forth communication will be established between the utility and the consumer. Consumers will get new sources of information directly through smart meters or through some form of energy gateway. This information will be fully utilized and communicated to consumers by means of the Home Energy Display Device (IHD).
Home energy display devices enable utility customers to track their energy usage graphically or graphically based on the kilowatt hours used. It provides most types of energy-aware information that customers need: total energy consumption, real-time pricing, and comparative analysis with general energy usage.
IHD is actually a portable or wall-mounted display (for new homes) that communicates with utility meters (electricity, gas, water) and other home-device-enabled communications (eg, using ZigBee, wireless MBus) . When ZigBee is enabled, it can be set to act as a coordinator or router. These communication features enable it to receive real-time customized information from utility companies about billing, energy prices, and more.
Common wireless communications are ZigBee (802.15.42.4 GHz, commonly used in the United States) or wireless MBus (less than 1 GHz, more commonly used in Europe). This type of communication can be enabled by a system-on-a-chip (MCU and transceiver) or by an MCU running another profile stack (connected to a connected radio transceiver), depending on the system topology. The hardware and software involved in both cases are available from Texas Instruments and the TI Developer Network. High-end IHD can also choose WIFI technology that is now available.
Multiple categories of IHDs will differ from each other because of the optional graphics and information capabilities, which will naturally lead users to choose different embedded processors:
Cost-optimized IHDs, such as the MSP430, are typically used as main processors: they are designed for ultra-long, durable battery-powered designs that are perfectly optimized for flash, processing power and low power consumption. Its integration allows for easy connection to communication modules (UARTs using SPI) or RF transceivers. Some members of the family can drive segmented LCDs with on-chip LCD drivers and provide on-chip analog-to-digital converters; they can be used to implement touch screen functions when not using a display with an integrated controller. In addition, a variety of inputs/outputs can be programmed to implement button options. For solutions below 1 GHz, the integration can be further optimized with the CC430, combining MSP430 and sub-1GHz transceivers in a low-power RF system-on-chip without the need for an LCD segment controller. To achieve ultra-low standby current to maximize the life of lithium-ion batteries, TI offers LDO linear regulators with standby currents as low as 0.5μA. TI offers a buck/boost DC/DC regulator for ultra-low input voltages, which is ideal for powering MCUs from batteries (including 1 to 3 alkaline, NiCd or NiMH batteries). Powering the MCU from a battery as low as 0.7V, coupled with high efficiency, these regulators can extend battery charging time and increase application uptime.
Mid-Range IHD - If you need more processing power, and if developers are looking for a more advanced graphics library, the TIStellarisCortexM3 microprocessor family offers a wide range of pin-to-pin memory options, interface options, and encryption solutions. the best choice. This family of products comes with an embedded graphics library, available through StellarisWareSoftware. Based on system constraints such as limited cost or maximum efficiency, TI offers optimized products to power Stellaris MCU systems, including high input voltage regulators that can power MCUs with standard 24V DC lines, which are commonly used in residential doorbells and security systems. .
High-end IHD - In order to support more interactive options such as Linux and other operating systems, processing power and interface will enable users to choose ARM9Sitara microprocessors, such as AM1808. The MPU provides a fully integrated LCD controller unit and provides a variety of software libraries for implementation. To achieve a certain power, these devices require a 1.2V regulated core, 1.8V and 3.3V. In addition, sequencing power structures are becoming the norm for high performance DSP systems. The USB interface can also be found on high-end displays that are primarily used to charge or upload multimedia content. TI offers a complete low cost, integrated power management solution for these types of high power multi-rail systems.
Micro switches
Micro switches, as the name suggests, use very small force switches. It is the switch that the external mechanical force acts on the moving reed through the transmission element, and the fixed contact and the moving contact at the end of the driving reed are quickly turned on or off. There are small, ultra-small, super-small and so on in size. Functionally waterproof. Furthermore, Metal Switches, Automotive Switches, Push Button Switches are also our competitive products.
This Mini Micro Switches are used for automatic control and safety protection in devices that need frequent switching circuits. They are widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, and aerospace, aviation, ships, missiles, and so on. Tanks and other military fields have been widely used in the above fields. The switch is small, but it plays an irreplaceable role.
There are many kinds of Waterproof Micro Switches, and there are hundreds of internal structures. There are common type, small size and super small size according to the volume. According to the protective performance points, there are waterproof type, dust-proof type, and explosion proof type; according to the dividing form, there are Single type, double type, multiple type.
The Electric Micro Switches, has a small contact spacing and a quick acting mechanism, and the contact mechanism that performs the switching action with a prescribed stroke and force is covered by the outer casing, and has an external actuator and a small outer shape.
