PLC based Automation solutions and Communication system
The factory automatic solution uses the UA controller to obtain the information such as the safety status of the production line and the temperature, voltage and current status of the inverter, then transmits them to the SCADA control system for real-time factory management. Besides, the 4G wireless can help to integrate the machine status, temperature, product yield, production parameters, electricity consumption, etc. into the ERP system via the MQTT protocol for managing the production of the global factories.
The environmental safety should be considered during constructing. For those old buildings, this can be solved by adding new technology products, such as those devices which could do monitor and detect CO, CO2, PM2.5, formaldehyde (HCHO), methane (CH4), temperature, humidity, body motion detection, infrared, and etc. ICP DAS environmental sensor series not only detect the environment and trigger the alarm, but also create the linkage reaction among devices to notify the control center and make follow-up process immediately. With ZigBee wireless series, when detecting the smoke, it can immediately trigger the alarms, connect to smoke dampers, enable the indicator for escape route, notify the control center, and evacuate people with the instructions to reduce further disaster.
Robustel, one of the top manufacturers of industrial-grade IoT and M2M solutions worldwide, recognized these needs. Therefore, it built an Elevator VoLTE Emergency Call Solution, a comprehensive and seamless response to the communication needs of the elevators. This elevator solution addresses the challenges posed by a variety of elevator systems. It also meets the standard for dependable 4G gateways, guaranteeing excellent quality and beyond the usual 3C certification requirements.The Robustel Elevator VoLTE Emergency Call Solution seeks to improve emergency communication within elevators by using state-of-the-art technology while maintaining safety. This will guarantee that assistance is constantly just a phone call away.The communication network for an elevator VoLTE emergency call solution is shown in the diagram below. It makes use of both wired and wireless connections and the EV8100 to guarantee dependable communication between the emergency services, the elevator, and the IoT Cloud for management and monitoring.
The rapid development of the city, the extension of the sewer network, and the increase in sewage, the traditional manual monitoring method cannot detect the source of pollution or disaster early and correct it immediately. The water treatment system is mostly equipped with monitoring modules, recorders, communication cables, and other equipment to achieve monitoring purposes. In order to avoid road excavation from affecting traffic and improve construction efficiency, ICP DAS uses ZT-2571 / ZT-2510 to take advantage of ZigBee wireless communication with low- interference and long distance. Provides the most immediate disaster prevention information to the monitoring unit by sending the sensing data back to the monitoring center.
The NT-RTU-23 takes into account the varying budgetary, interface and connectivity requirements of customers to create a simple and cost-competitive networking solution for customers deploying IoT solutions in industrial environments such as water, gas, electricity, factory automation and warehousing.The NT-RTU-23 runs on Robustel's own Linux based Operating System, Developed entirely in-house, this gives way to a very high standard of technical support and high reliability. Robustel offers a Software Development Kit (SDK) to allow additional customization by using C, C++. It also provides rich Apps to meet fragmented IoT market demands.
In some factories, H2S is one of the harmful gases. Due to the colorless and odorless are two characteristics quite hard to find or feel it, sometimes the workers inside the factory get injured inevitably. Joint liability from the injury brings the company a massive fines. DL-1026 H2S detector module can put in the spot. It equip with standard industrial protocols and with high flexible to integrate information from devices and transmit back to control center. When the concentration of gas is too high, DL-1026 can also send alarm signals to inform relative person to evacuate people there.
Users can integrate information about pressure, fl ow, leakage, temperature, earthquake, access control, and on-site image at gas pressure regulation stations via wire or wireless communication, and send the data back to the control center instantaneously for management. When an anomaly occurs, the control center can remotely activate an emergency shut-off valve to stop the gas supply, thereby avoiding accidents occurring. Conducting remote unifi ed monitoring for all gas equipment can increase the benefi ts of overall gas monitoring system, reduce labor and time costs of gas providers, and ensure peopleís safety.
Gas Pressure Regulation Station Monitoring System in Taiwan- AVEVAô Edge Solution Overall Monitoring System Structure About twenty pressure regulation stations in total. Every station requires to monitor pressure and switch status of the control valves of gas lines, and on-site real-time images. Users can use a PAC controller, together with AI/DI modules, to monitor pressure of on-site gas lines and the switch status of control valves, and use the graphic control software AVEVA Edge to display and record the data of a pressure regulation station. Together with the seismograph for earthquake detection, when an earthquake occurs, users can immediately stop the gas supply remotely. Pressure regulation stationsMonitoring system structure.
Control center- Structure of the monitoring system. AVEVA Edge, a graphic control software running on the monitoring server, can exchange and integrate information of gas pressure rapidly with the tag variables of the pressure regulation stations through TCP/IP worksheet. The exchanged data includes the realtime information, (for example, inlet/outlet pressure, diff erential pressure across fi lters, earthquake monitoring,) the gas pipeline map with gas pressure in each section of pipeline, and the real-time image display on the site. AVEVA Edge is equipped with the warning function. When the alarm is triggered, it will fl ash and make a warning sound to notify the management personnel in the control center. AVEVA Edge can be used in conjunction with the GTM-201 modem to send SMS to inform related personnel about the on-site status. Managers being granted permission can remotely monitor the real-time information of equipment at the pressure regulation station through the browser of a computer or smartphone. All the monitoring values will be saved in the database of a server for data analysis or report.
Nimbus router is a Dual Ethernet port (LAN + WAN) 2G/3G/4G/LTE router with advanced software functions and a dedicated serial port at a very competitive price point. Offering a choice of (3-wire) RS232 or (2-wire) RS485 instead of the Digital Input and Digital Output.
This means that RS232 and RS485 devices, including Modbus RTU equipment can connect to the internet directly. The Ethernet port can be independently configured as WAN, LAN1 or LAN2 and Ethernet port 1 as LAN1 or LAN2.
Modbus RTU to Modbus TCP Gateway built-in Ethernet, Wifi and 4G internet connection options with auto-failover
Fully programmable Linux environment with excellent SDK Documentation
Full SMS control for diagnosis and recovery from data network problems
Very small footprint for space-constrained applications
