eGlobal has developed a series of advanced new-style e-systems like lighting monitor system, energy-saving control system, e-energy billing system and so on. This kind of product with widely future bases on the technique of Power-line-carrier communication and lighting modulation and so on.

   Take the example of Navigation lighting automatic monitor system:

   At present, there is no computer monitor system for navigation lighting in the airport and the navigation lighting depends on people to scout. The tower and the lighting station can not detect the problems when there is something wrong with the lighting tools and loops. Therefore, if there is a flight at this time, it will threaten the flight safety seriously. In order to assure the flight safety, it is necessary to build up a computer monitor system since the existing systems have no functions of real-time monitoring, detecting the problems, controlling in grades and alarming.

Automatic navigation lighting monitoring system:

• System must have credible topological and backup system to be sure that the navigation lighting can be monitored continuously when part of the system happens wrong.
• The system must have management policy of control right in order to deliver the right on necessary time. When the control right and sub-system is invalid, it will be reclaimed automatically.
• The system should keep the interface to communicate with the information center of airport and the information system of the other airports can interactive with it.
• The design of this system should follow up the principle of upgrading and expansion.
• All the monitors should have the backup of UPS.
• The system should have a series of equipment interface which can connect the system network with the other various lighting control and power equipment and monitor them. E.g.: dimmer, transformer substation power supply testing system, diesel generator monitoring system and so on.
• The user interface should supply the model chart of flight area (e.g.: runway, taxiway and so on).
• The user interface should also provide the installation model chart of equipment and make a warning with different color when something wrong happens.
• When there is something wrong with the system, the function of sound alarm should be provided.
