I. Summary For real-time monitoring of the power supply of fire-fighting electrical equipment, by detecting voltage, current, switching status and other related parameters, determine whether the power supply of the fire-fighting equipment is in the normal operating state. If a fire occurs, ensure that the fire-fighting equipment can normal operation.
Second, the fire equipment power monitoring system composition
The monitoring system for monitoring the power supply status of fire-fighting equipment and generating an alarm signal when the power supply experiences over-voltage, under-voltage, over-current, phase loss, interruption of power supply, etc., and the fire-fighting equipment power status monitor, voltage sensor, and current sensor , voltage / current sensor and some or all of the equipment.
1. Fire equipment power status monitor
2. Fire Equipment Power - Main Module
3. Fire equipment power supply - sub-module
4. Fire equipment power module - combination wiring
Three, two bus features advantages:
1. Easy to choose and expandable (one power distribution box occupies one point): The new fire-fighting equipment power monitoring sensor uses a modular, modular free collocation scheme. There are a variety of combination options to choose from, which can meet a variety of on-site needs.
2. Two-bus communication, convenient on-site wiring, reduced debugging difficulty:
The second bus is a technology that combines a power supply line and a signal line with a four-wire system (two power supply lines and two communication lines), and realizes a common bus for signals and power supply. The second bus saves construction and cable costs, and brings great convenience to site construction and post-maintenance. The wiring does not emphasize hand in hand.
3. The sensor uses the plug terminal:
The use of plug-in terminal wiring, convenient field wiring and post-sales replacement and maintenance operations.
Fourth, note:
1. The slave module is not used alone, but only used in combination with the master module;
2. The slave module does not occupy the host position;
3. The main module address setting uses an encoder.
V. System Networking A small-scale construction network program:
Without regional extensions, the number of monitoring points is ≤ 256
Small Building Network Project II:
Without regional extension, the number of monitoring points is less than 200
Medium-sized construction network plan:
Add regional extensions, monitoring points ≤ 1024
Large-scale construction project of single building network:
Sixth, the main interface of product software system operation
Consisting of four parts: “Login†button, “Interface Titleâ€, “Feature Listâ€, and “System Status Barâ€, you can quickly query the current monitoring status and can also be used for staff login operations.
User login interface
After inputting the correct user name and password, the system status bar will directly jump to the current user's operation interface, and the current login user and function list can be displayed.
Rights Management Interface
The interface is provided with three operation levels. The operation permission levels are "super administrator" → "administrator" → "operator", in which the high level can add low-level new users.
Condition Monitoring Interface
The interface graphically displays the working status of the currently monitored fire door visually. After clicking the fire door icon, the system displays the detailed information of the fire door.
