Three applications of crystal oscillators in industrial control

    With the rapid development of technology, the demand for precise time synchronization and stable clock signals in the industrial and building automation fields is increasing day by day. Crystal oscillators play a crucial role in providing stable clock signals in these fields.

Building safety

The industrial security system aims to protect manufacturing facilities from unauthorized access, safeguard sensitive data and intellectual property, and ensure worker safety through monitoring systems and access controls.

Electronic devices focused on security encompass a wide range of technologies, including:

-Surveillance camera

-Access control system (including access cards or biometric scanners)

-Intrusion Detection System (IDS)

-Biometric authentication devices: such as fingerprint recognition, facial recognition, iris recognition, etc

Safety sensors (including motion, heat, or sound)

-Electronic lock/control system

Crystals and quartz crystal oscillators are crucial in the design of safety equipment, helping to improve the stability, reliability, efficiency, and resilience of safety systems under various environmental and operating conditions.

Typical protocols used in security applications include Wi Fi, Bluetooth Low Energy (BLE), Z-Wave, Zigbee, Controller Area Network (CAN), RFID, and GPS for location tracking.

lighting

In most industrial environments, lighting is a key factor affecting task performance, quality control, safety, energy efficiency, and environmental control.

Industrial lighting can be extended to many end use cases, such as:

-LED (Light Emitting Diode) lighting fixtures

-Intelligent lighting

-Motion sensor light

-Lighting control system

-Solar Lamp

-Emergency lighting

-Lighting sensors and accessories

Crystals, quartz oscillators, and real-time clocks help improve the stability, reliability, and functionality of industrial lighting systems. Frequency control reappears, created by crystals, quartz oscillators, and real-time clocks to execute commands, continuously trigger functions with precision, and record accurate data.

Building automation system

Building Automation Systems (BAS) provide intelligent control and connectivity necessary for optimizing building operations. Building Automation Systems (BAS) include various electronic devices designed to automate and control various building systems, such as:

-Programmable Logic Controller (PLC)

-Building Management System Controller (BMS)

-Thermostat and HVAC controller

-Lighting control system

-Access control system

-Energy Management System (EMS)

These centralized systems require frequency based solutions: issuing commands, synchronizing events, and transmitting data to control each process from one location. Real time clocks are also commonly used in BAS systems to maintain time even when specific infrastructure is shut down.

Frequency control requirements for industrial automation

In the field of industrial automation, precise frequency control is of decisive significance for the stable operation of the system and the improvement of production efficiency. Therefore, when choosing a crystal oscillator, we need to focus on the following key characteristics:

Resistance to impact and vibration, which are crucial for durability in design, need to be considered

Long service life, able to withstand environmental factors experienced by industrial facilities

Wide temperature range, suitable for facilities with temperature fluctuations, such as components near machines that emit heat

High precision, high stability, suitable for applications that require data processing and communication
