telecom dynamic environmental supervision system for BTS station outdoor cabinet

1.Overview This is a small high-reliability environment monitoring unit developed to provide environment/device control and remote monitoring for communications base stations, integrated equipment rooms, and out-door cabinets. The monitoring unit monitors important environmental factors such as temperature, humidity, smog, water penetration, access control, vibration/leaning, main distribution frame (MDF), and surge protection device (SPD). When any value collected by a sensor exceeds the preset threshold, an alarm is sent through the LCD, buzzer, or system log. The monitoring unit also provides complete device detection functions, such as switch power status detection. Through a preserved custom interface (optional), the unit can be connected to another sensor in main contact point output type. 2.Features W-TEL monitoring unit is designed for the outdoor cabinet application. It height is 1U-2U and suitable for standard 19-inch rack mounting. Front cabling, friendly installation, greatly facilitating testing, field commissioning and remote monitoring to all sensors for customers. 1>20-channel digital signal input with optoisolators can access the smoke alarm, door alarm, water immersion, SPD, MDF alarm, input AC failure, LLVD. The fire alarm has the reset function that prevents wrong alarming 2>4-channel temperature detection can sense temperatures of the main equipment cabin and battery cabin respectively 3>Humidity detection can be used to sense the humidity of the main equipment cabinet 4>Optional Chinese/English display module facilitates parameter checking and setting on site 5>Relay output can be used for controlling lamps, emergency fans and electronic locks 6>With operating indicator, alarm indicator, and buzzer 7>Card-reader interface supports mainstream card-readers to realize smart access control functions with the help of electronic locks 8>Setting the LED in the cabinet to on/off when opening/closing the door through the access control function 9>W-TEL monitor can be connected to the air conditioner, heat exchanger, power supply, and electric meter through the isolated RS232/RS485 port 10>The main equipment offers standard isolated RS232/RS485/RS422 communication interfaces for direct connection to wired or wireless MODEM, and supports Ethernet, optical fiber, E1 and other interfaces via optional conversion interfaces 11>It also offers 5V, 12V and 24V output with short-circuit protection for external sensors and electronic locks, so that you need no additional power supply
