Avalon Engineering developed a LonWorks operator panel with a LonWorks network interface allowing the operator to interact with multiple devices on the LonTalk network. Devices may include temperature sensors, switches, controllers, or any parameter associated with facility management or other control systems. Avalon Engineering developed the hardware, software, mounting panel, and membrane keypad.
Avalon Engineering developed an application specific operator interface and controller for an industrial control product featuring Microchip PIC18 microprocessors and Modbus RTU communications. An optional expansion module adds Modbus/TCP capability, and the capacity for an embedded web site.
Avalon Engineering developed a sensor interface board that monitors voltage and current for application specific industrial lighting. A discrete version tripped a relay connected to a PLC upon alarm and indicated status using LEDs. An intelligent version communicates with the PLC using Modbus.
Avalon Engineering developed a remote alarm monitoring system that monitors sensors connected directly to local hardware, sensors connected via the LonTalk network, or sensors connected via Ethernet using the Modbus/TCP protocol. Alarm notifications may be made by SNMP traps, writing to a remotely connected Modbus/TCP register, or by writing to a LonTalk variable found on a remote node. The system is configured using an SNMP manager written in Visual C++ by Avalon Engineering. Data scaling, alarm thresholds, and action to take upon detecting an alarm condition are all configured via the SNMP manager tool.
Avalon Engineering expanded the network enabled remote monitoring system to include isolated signal conditioners for the analog inputs. The isolated millivolt inputs are used to monitor DC current shunts in battery backup systems for telecommunications. Battery voltage, temperatures, and room humidity are also monitored. Contact sensors are used for intrusion detection and for detection of alarms in related legacy equipment which is not network enabled.
Avalon Engineering played an integral role in development of a compete End to End Solution bringing devcie level data up through IT infrastructure to web deployment. Avalon Engineering applied a network enabled remote monitoring system to monitor various data points in a power co-generation facility. The system software is configured to provide report-by-exception upon occurrence of alarms. The link to a 24-7 call center is via satellite. Status may be polled via satellite as well (link is bidirectional), and the call center status information is web enabled allowing local technicians to access status information via the Internet with a standard browser.
The local area network uses LonWorks for cost effective communication among devices. A custom gateway gathers data via LonWorks, and makes it accessible to the WAN using Modbus/TCP and SNMP protocols.
Avalon Engineering also developed a discrete alarm monitor. This system uses a LonWorks processor, discrete inputs, and relay outputs. The discrete inputs are used for sensing switch closures from equipment that provides switch closures upon certain fault conditions. In addition, network messages from other monitoring nodes are accepted by this node, and relays are activated according to a response matrix when an alarm occurs. This system is used in clean rooms in semiconductor fabrication facilities.
If you don't see a project represented here that has anything in common with your project, call or email us with a general description of your requirements. Many of the projects we work on are confidential such that we cannot publish any detail on the web. So if you don't see it here, that doesn't necessarily mean we haven't done it.
Avalon Engineering developed a LonWorks based I/O node with 30 I/O points in a DIN rail mount enclosure. The 16 analog inputs include richly featured alarm capabilities. The unit also includes 8 relay outputs, 2 pulse inputs, and 4 analog outputs. This product passed FCC Class B and CE Mark certification on the first attempt. The product is also LonMark certified.
Avalon Engineering developed a gateway that translates LonWorks network variables to Modbus registers accessed via the Modbus/TCP protocol. Auto sensing 10/100BaseT Ethernet and IEEE 802.11b are both available in the same platform. Data is also accessible via the SNMP protocol on the Ethernet side. The product is available as a general purpose gateway, and the platform can be custom programmed for application specific configurations.
Avalon Engineering developed a proprietary wireless "smart sensor" to monitor a specific condition. The sensor incorporates a low power transmitter. The receiver is worn like a pager, and signals the person wearing the receiver when an event has been detected by the transmitter. The transmitter periodically sends its status, and the receiver compares the transmitted sensor level to the user programmed threshold to determine if an alert should be initiated. The receiver will either beep or vibrate when an alert condition is detected. Both the transmitter and receiver are battery operated and microprocessor based. Low power design and intelligent power management extend battery life by greater than 20 times.
Avalon Engineering provided software and hardware development for a handheld portable lab instrument. The device senses certain chemical properties using IR absorption and other technologies. A user friendly menu and graphic display make the device easy to operate. Data is displayed immediately upon completion of a test. Several hundred test data points may be stored internally and later uploaded to a PC. The data may be transferred via the RS-232 serial port or an optional wireless link.
Avalon Engineering developed an alarm monitor for the semiconductor industry. The system uses a LonWorks processor and several analog inputs to monitor sensors. Status is sent over the network, and relays on other network nodes are triggered in the event of an alarm condition. This particular application was used for toxic gas monitoring; however, any type of analog sensor could be used for a variety of monitoring applications.
Avalon Engineering developed a cost effective multi-purpose controller with LonWorks network connectivity. The board has been used to implement a variety of HVAC functions. These include boiler, chiller, and air handler. All of the controllers are networked using LonWorks. The network includes a central PC based user interface to monitor and control the environment of the building.
Avalon Engineering developed a system that provides power metering or submetering for remote sites. A LonWorks enabled power sensor is used along with current transformers to monitor power, power peaks, power factor, etc. This information is linked via LonWorks to a serial gateway and data logger. The data logger periodically calls a central location to upload power data via modem. The recording period may be remotely set or changed. Recording data in relatively short time periods allows power usage profiling, leading to energy use evaluation and potential energy savings. The LonWorks based power sensor may also be used as a sensor in a larger system based on the the Ethernet enabled monitoring system.
Avalon Engineering developed a dial-up remote alarm monitor for installations without wide area network connectivity. This system uses a LonWorks processor, analog and discrete inputs and outputs, and a serial gateway with integral modem. Devices are connected directly or via the LonWorks network. Alarms will initiate a call out. The central monitoring facility may also call in to the monitoring system to poll status. In addition, relay outputs may be activated in response to alarms, or upon command from the central monitoring facility. This system was designed for remote telecommunications equipment monitoring. The entire system may be run on the battery backup voltages commonly found in telecommunications installations.
Avalon Engineering assisted in the development of a dimming lighting controller used in commercial retail environments. This system provides both on/off and dimming control of flourescent and HID ballasts for energy management. The system consists of a LonWorks processor, analog inputs for ambient light sensing, analog outputs for dimming control, and relay outputs for light switching. A similar controller could be readily configured with Ethernet connectivity instead of LonWorks.
