Singapore Changi Airport is a major aviation hub in Asia. It is located in Changi, about 20km east-north-east of Singapore centre. The airport is operated by the Changi Airport Group (CAG) of the Civil Aviation Authority of Singapore (CAAS).
Lee-Dickens has been providing integrated remote control and monitoring systems for air traffic control (ATC) and air traffic management (ATM) systems worldwide for more than two decades. We have a broad customer base, including in Europe, the Far East and Africa. We provide our products and services to both civil and military customers.
Integrated remote control and monitoring of airport CNS systems
We provide turnkey solutions for the integrated remote control and monitoring of airport CNS systems including primary and secondary radar, air-ground radio communications, instrument landing systems and airfield beacons, as well as a broad range of ATC tower equipment.
In addition to the front-line services listed above we provide control and monitoring of the support services such as UPS, standby power, fire detection, intruder detection and air-conditioning equipment as well as temperature and humidity monitoring. Our solutions also provide alarm detection, alarm annunciation and reporting, automated channel surveillance and control, historical data recording, and trending and performance monitoring.
Safe, reliable and consistent operation is an essential part of our solutions. Our proven track record provides our customers with confidence in the solutions we offer.
Human machine interface (HMI) for airport field equipment
Sitewatch™ HMI is specially designed to meet ICAO requirements. With an internationally recognised symbol set, Sitewatch provides information for both engineers and managers regarding the status of airport equipment and services.
Sitewatch HMI is designed to provide a simple, intuitive and consistent interface to a wide range of field equipment, allowing the operator to quickly assess the condition of systems and services and to safely and rapidly respond to changes.
The HMI uses a mouse as the operator’s pointing and control device, and high-resolution active colour graphics displays to dynamically indicate the status of the remote site equipment.
The display area has a number of dedicated non-overlapping panels, which are used for system alarms and events, operator log-on, screen navigation and for mimic displays. Sitewatch uses an advanced ‘single click’ feature which provides an immediate and direct navigation route from an alarm displayed in the alarm and event panel to the relevant mimic diagram and point.
Mimic displays are configured in a logical hierarchical format while the operator log and the online help are always accessible.
Airport control and monitoring remote terminal units (RTUs)
The current generation of Sitewatch RTUs are 32-bit ARM9 microprocessor-based devices. Embedded with the latest technology, they are offered in a range of enclosures, from single wall-mounted boxes to the more standard 19in rack-mounting format.
Our RTU family can be used in different range of airport control and monitoring applications depending on the field equipment in question. The main features include combinations of plug-in processors and I/O modules to handle large input/output point counts; system health monitoring for self monitoring; and multiple, configurable communication ports for handling different type of communications with third-party equipment.
Remote control and monitoring engineers and project managers
Through our wide range of products and highly experienced engineers and project managers we can provide turnkey solutions. This covers all aspects of the work, from an initial assessment of the requirement to the risk assessment, design, development, manufacture and ultimate commissioning of the solution.
All of our work is carried out under the auspices of our design engineering practices and procedures, which are approved to ISO 9000:2008 and ISO 9000-3 Tick-IT.
Airport remote control and monitoring project management
An essential ingredient for the success of any project is sound project management. Based on management-by-objectives and critical path evaluation and with the experience of our staff, we have developed project procedures and evaluation systems that are designed to ensure that timely decisions are made based on accurate information, thus ensuring that projects are completed on time and within budget.
Our project organisation is centred on a qualified and experienced project manager, who reports directly to the company’s managing director. The functional design specification (FDS) combining the customer requirement specification and the tender response is written by the project manager. The FDS is agreed and signed off at a critical design review (CDR) and becomes the project definition document (PDD) used by both Lee-Dickens and the customer to evaluate progress.
Once the critical design review is completed, the project team is resourced to meet the agreed project timescales. The project team carries out the development work, the factory acceptance tests and then the site acceptance tests once the system is installed and commissioned.
