SF6 monitoring host (touch screen)JC-DL/1-01H

1、 Function Introduction

SF6 monitoring host (touch screen)，Including CPU main control unit, alarm unit, communication unit, and display unit. Real time collection of data from various gas detectors on site, determining whether they exceed the standard. If they exceed the standard, output actions such as sound and light alarm and fan startup will be carried out. The specific functions are as follows:

☆ Real time display function of telemetry and remote signaling for all monitoring points in the environment

☆ Real time display of alarm information for all monitoring points in the environment

☆ Fixed value setting function

☆ SF₆Gas concentration exceeding the standard and oxygen deficiency alarm function

☆ Hypoxia or SF₆Excessive concentration, forced exhaust function

☆ Automatic fan start function upon alarm

☆ Automatic timed exhaust function

☆ Manually force all fans to turn on or off,

☆ Historical data query, display, and storage functions

☆ Remote sensing value historical curve trend query and display function

☆ Enter the GIS room and automatically report the current environmental status function

☆ Multiple monitoring point configuration function in different regions

☆ Multi point networking function, can provide communication protocol and substation backend database docking (reserved)

☆ Provide a universal communication interface, with reserved functions for interfacing with backend monitoring and fire protection systems (reserved)

☆ Alarm information storage and recording function

☆ Sound, light, and voice alarm functions

☆ Remote alarm function

☆ Human body infrared detection and sensing function

☆ Data remote transmission function

J1 is SF₆Monitor the communication interface of the host. Mainly used for data communication between devices and the background, hosts and terminals, and B-code synchronization. The default configuration includes 485A1, 485B1, and network port as remote communication interfaces for the backend host. 485A2 and 485B2 are interfaces for connecting gas detectors and fan controllers. IRIGB+and IRIGB - are B-code time synchronization interfaces.

J2 terminal includes SF₆The input/output and DC24V output of the monitoring host are detailed as follows.

J2-1, J2-2: Sound and light alarm passive null node (optional as a universal output node)

J2-3, J2-4: Remote alarm passive null node (optional as a universal output node)

J2-5, J2-6: Fire linkage alarm empty node

J2-7, J2-8: Device alarm empty node, needs to reset and return

J2-9, J2-10: Passive input node, used for infrared input to start the fan

J2-11, J2-12: Active input nodes (DC24V), used for fire linkage to prohibit the start of fans

J2-13, J2-14:24V DC power output

J3 is the input and output interface of AC220V power supply, and both AC220V input and output are controlled by the on/off of the device power switch.
