Lighthouse is the Proven Leader
Lighthouse has the largest systems installed worldwide. There are many things to consider when purchasing, testing, and/or expanding a system. Some of these include the following:

  1. Performance: Our system is by far the fastest system on the market under both normal and extreme conditions. The system was designed to multitask. The user can collect data from thousands of sensors, send alarms, watch log files, build graphs, send pages and do much more, all at the same time.
  2. System robustness: our system has a distributed architecture. Data collection, storage, and analysis happen dynamically throughout the system. Each node monitors its own state and that of the connections to other nodes. In the event of a failure, each node takes the appropriate action, assuring data integrity.
  3. Data redundancy: Our system has automatic data redundancy built in. If the main system goes down, our Area Control Units update data on the main system automatically when it comes back up.
  4. Sensor compatibility: Our system has an open architecture. It is the only system that has such a broad base of sensor libraries. The system allows our customers to use sensors from any manufacturer with any input. The open architecture philosophy will continue to be a part of all new versions and future system upgrades.
  5. Data backups and archiving: Specific ranges of data can be stored for historical access, or data can be auto-archived to a protected file in the event of a catastrophic failure of the main database.
  6. Reporting: Report features are designed by customers for customers. There are full color standard reports for graphs; charts, SPC graphs, and data tables, and a custom report package created to meet our customer’s summary reporting needs. These custom reports allow the customer to look at data from many, many perspectives and in many formats.
  7. Data Export: Our systems allow our customers to export data in several ways. Depending on the needs of the customer, the Lighthouse System can export data in anything from a simple CSV file, to an ASCII serial data stream, to a network data connection. This variety of data transmission modes allows the customer to have access to his data were he needs it. Data may be exported to common spreadsheet formats and through serial exports to third party reporting packages or to yield management systems.
  8. Alarming: Our system has many ways to alert our users that there is an alarm, including alarm lines on graphs at the point of use, alarm light sticks at any of the main viewing stations, buzzers for sound alert, and pagers for notifying key staff.
  9. Facility Maps: Facility maps are multilevel and hierarchical, allowing the customer to see the overall state of the facility and zoom into the area of interest intuitively. The maps can be customized and have adjusting functions for font size and layout.
  10. Data collection rates: In 1990, Lighthouse developed a data collection method called Adaptive Data Control. This data collection method allows our users to set the recording rate separately for alarm, warning, and normal conditions for each individual real-time sensor.
  11. Self-diagnosis: Our system has a self-checking protocol that notifies the user when system errors occur. This protocol allows the user to check the integrity of the nodes connected to the system. In the event of lost or corrupted data due to a communication error, the system adjusts to ensure that the data is properly received.
  12. Historical data review: Our system allows the user to keep massive amounts of data at their fingertips. By browsing through easy step windows, our users are able to recall, review, and report on historical data.
  13. Hardware connectivity: Our system is able to communicate with devices with all standard communication protocols. These protocols include TCP/IP, RS-232, RS-422/485, 4-20mA, 0-5v, 0-1v, 0-10v, Frequency, Digital input/output, RTD, 0-20mA, Modicon MODBUS, Allen-Bradley Data Highway Plus, and many more…
  14. Networking multiple sites: Our system allows for viewing from remote locations independent of the customer’s internal network. Remote dial and data transfers allow our customers to view data from around the world.
  15. Networking within a site: Our system has optional server-based software that allows our customers to set up clients connected to their network.
  16. Auto-Paging: Our sophisticated pager notification allows our users to notify key personnel in the event of an alarm, warning, or fault.
  17. Modular concept: Our system allows the user to expand from a simple system to a large system. All components are building blocks. As the system grows, all system components can grow with the system. As computer technology advances, we work with our customers to utilize each part of the computer to its fullest.
  18. Real-time data computation and analysis: Mathematical operations such as averaging and ranging can be applied to currently monitored data points, creating calculated data points. The customer can use the same types of data displays and alarming for calculated data points as for regular data points . Our system allows event monitoring, trend alarming, data filtering, and more.
  19. SPC Charts: Our system includes X-bar/R Statistical Process Control charts for monitoring any parameters of interest (temperature, particulates, air velocity, etc.).
  20. User Interface: The Lighthouse system’s user interface is simple and clean. Design simplicity shortens training time and allows the customer to take advantage of the full power of its features.
