CAN Bus-based Security Collective Control System

We offer the CAN Bus-based Security Collective Control System to meet different client's security requirements.

Product Profile:

Overview: the CAN Bus-based Security Collective Control System is mainly composed of the microcomputer control platform, CAN master controller, CAN repeater, CAN control terminal, centralized power supply (optional) and terminals (security products: emergency lights, smoke detectors, etc.)

System Advantages:

1.       Data transferred between the platform and control terminal by using CAN bus, simplified wiring, reduced construction costs, long-distance signal transmission, good anti-jamming performance, and quick data transmission;

2.       Conducting real-time monitoring of all components of the system, starting the alarm and displaying failure position once the failure found, and reducing the maintenance cost;

3.       When any disaster taking place, initiating the terminal-directed escape route, and increasing the building safety; very applicable to security requirements of schools, hospitals, office buildings and other public places.

This point is based on the application of emergency lights

Main Functions of System: (when used on firefighting emergency lights and fire alarm occasions)

1.       Platform Software

(1)    Displaying the working condition of all terminals (including mains supply shortage, load failure, communication failure, etc.)

(2)    Displaying the working condition of centralized power supply (including availability time of power supply)

(3)    When a fire alarm taking place, displaying information on alarm locations accurately

(4)    Self-test function provided, able to perform self-test operation from the platform software control terminal (self-test time and quantity controllable)

(5)    Emergency control of the output of terminal load can be conducted manually directly. No matter the mains supply is normal or not, the load is in emergent output condition

(6)    With the function of detecting battery performance, it is able to detect battery capacity (This point is based on the application of emergency lights

2.       CAN Host

(1)    When not in connection to the platform software, scan the working condition of the terminal dynamically in turn

(2)    When in connection to the platform software, scan the working condition of the terminal as directed by the platform software

(3)    Having received fire alarm signals, send commands to start all terminals to ensure the action of the whole firefighting system

3.       CAN Repeater

(1)    In the system, acting as a bridge between the host and the terminal, it sends commands and data from the host to the terminal, and condition data from the terminal to the host

(2)    In the system, the repeater enlarges the system capacity and greatly increases the access point quantity of the terminal. The host can receive a maximum of 100 CAN repeaters, with each CAN repeater to be connected to a maximum of 100 CAN control terminals, and one CAN host to monitor the network capacity of 100*100=10000 CAN control terminals

4.       CAN Control Terminals

(1)    Status detection function of double-input power supply 

(2)    Controlling the detection function of load output and load status (5W load min.)

(3)    Load straight-through function (in this case, the load output is not controlled by the system but directly in full power output condition)

(4)    Detecting fire signals and sending alarm information to the host

Note: all products of our Company are customized and mass produced according to customer requirements.
