Build a Building Automation System That Can Run on Battery Power for Decades

low power consumption

Using MSP MCU, engineers do not have to sacrifice functionality in building automation systems or charge batteries. By combining low-power design technology with energy harvesting, battery replacement in thousands of remote sensors can be reduced or avoided. In case of battery replacement or power loss, the system state can be maintained due to the speed and durability of FRAM and compute through power loss (ctpl) software facilities. In fact, the application can be reconnected immediately where it was interrupted without recalibration or hard start. With energytrace â„¢ With the real-time power distribution capability of the technology, the optimized MSP microcontroller can make full use of all the power of the application.

Intelligent simulation integration and miniaturization

Many people may not understand the real meaning of "MSP". This name actually represents "mixed signal processor". One of the main objectives of Ti is to integrate analog peripherals to reduce the complexity, size and cost of building automation system. The integrated high-performance simulation function allows engineers to add local interface connectivity to each sensor in the building automation system, so as to realize functions such as sampling and processing.

Reference software and connectivity protocol

Whether wired or wireless connectivity is added to the building automation system, MSP MCU hardware and software can make the device run like a host controller and seamlessly connect with multiple connectivity solutions at the same time. Ti also provides Ti design reference designs, wired and wireless stacks and algorithms, including the recently released ctpl and iqmathlib libraries, to speed up development and reduce the required connectivity (RF) expertise.

Below, we will list some of the most common building automation applications to see how low-power MSP MCU meets their design needs.

Occupancy sensors and motion detectors are essentially sensing applications, including a series of technologies for detecting the number of people in a fixed area. Usually, this detection is automatic and unknown to the detected person. Sensing technologies such as infrared (IR), ultrasonic, sound and image recognition applied in areas such as offices, classrooms, conference rooms, bathrooms, storage rooms or corridors. These sensors or detectors can be used to save and save power and energy, while also helping to add intelligence and data analysis to improve the security situation in the building.

MSP MCU can provide the following advantages for occupancy sensor applications:

-Low power consumption for simpler power supplies

-Miniaturized size for size constrained applications

-Integrated intelligent simulation function for passive infrared (PIR), thermocouple, inductance, ultrasonic and other sensor inputs. For example, the 14 bit high-speed ADC on msp432 MCU can be used for advanced capture algorithms and improve performance

-Aes256 and IP encapsulation for enhanced system security

-Nonvolatile embedded fram for firmware upgrade and data logging

In addition, MSP MCU also supports 6LoWPAN and simplelink ™、 Multiple communication stacks such as KNX.

Electronic lock (e-lock) is a mechanical and electronic closing device that can be opened by providing confidential information or combination by entities such as key, door card, digital keyboard, fingerprint, RFID card and security token. These products are mainly used to help improve security to ensure legal access to specific areas.

MSP MCU can provide the following advantages for e-lock applications:

-Ultra low power consumption that can be operated by battery for more than 10 years

Glass crack detector is a detector that can detect whether a window is broken or damaged. It is usually used in applications such as electronic anti-theft alarm. The glass crack detector generally monitors the noise or vibration from the glass through the microphone. If these vibrations exceed a specific threshold, the detector circuit analyzes these vibrations.

MSP MCU can provide the following advantages for glass rupture detector applications:

-Ultra low power consumption that can be operated by battery for more than 10 years

-Reference design and software, with robust algorithms for error triggering or monitoring

-Higher security achieved by aes256, local security zones for IP protection, and firmware upgrades

-Low power 14 bit high speed ADC for advanced capture algorithms and higher performance
