The main part of any telephone system is the telephone exchange, and its function is to maintain the proper environmental conditions for the system's sensitive devices. Temperature, for instance, is one of the most important environmental parameters that telephone companies have to take into consideration.
An efficient temperature monitoring system has to 'know' the temperature everywhere in the telephone exchange room. Data concerning temperature values has to be sent to various points, such as the operators of relevant airconditioners and the general control centre. Furthermore, the system has to control and monitor the airconditioners and any malfunction must be detected. In addition, the monitoring system has to be very flexible and easy to modify to facilitate future expansions.
The main part of the temperature monitoring system consists of several ADAM-4011D thermocouple input modules with LED displays, which are mounted across the telephone exchange cabinets. Every ADAM-4011D unit is linked through an RS-485 network to a panel PC wall-mounted in the room. The ADAM-4001D units are supplied by an independent power source and every digital alarm output is connected to an independent system of sirens and alarm lights, which guarantee efficiency even during computer system failures.
The panel PC is a touch screen PPC-102T bundled with VisiDAQ software. Its main function is to collect data from every ADAM-4011D unit and display temperature information on the screen. Authorised operators easily set or change alarm parameters by using the touch screen.
The ADAM-4050 digital I/O modules formed the second part of the system and are located in a different room to monitor the airconditioners. The ADAM-4050 units detect every alarm and have some primary control capabilities, such as 'start', 'stop', 'temperature down/up'. In this room an additional PPC-102T unit facilitates user-friendly monitoring and control.
In the top flow, a PPC-140T panel PC enables monitoring of the entire system and maintains the proper temperature in the telephone exchange room. All panel PCs are connected by 100 MB Ethernet with IPX/SPX protocol, which allows data exchange between the three parts of the system.
The solution, based on the ADAM modules, panel PCs and the VisiDAQ software package, provided a complete system which can be easily modified and upgraded.
