Abstract

The invention discloses a fire-fighting equipment control system based on a CAN bus. The fire-fighting equipment control system comprises a CAN bus communication circuit, a master control module, and a plurality of controller nodes. The CAN bus communication circuit comprises at least one CAN controller and at least on CAN transceiver, has a receiving and transmitting function, and may filter messages. The master control module is connected with the CAN bus communication circuit, may monitor the operating state of the system, and controls the operation of the system. The plurality of controller nodes are connected with the CAN controller, may independently process corresponding data, and achieves communication with the CAN bus communication circuit. The distributed architecture based on the CAN bus may add and delete node equipment any time, is simple in logical relationship, and reduces a failure rate. A fire-fighting equipment fuzzy control method based on a CAN bus is provided for determining whether to activate a smoke evacuation device or a fire-fighting water pump by computing a fire assessment coefficient, preventing smog sensor misjudgment, and achieving accurate fire extinguishing.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment control, in particular to a CAN-bus-based fire-fighting equipment control system and a CAN-bus-based fire-fighting equipment control method. Background technique [0002] As the main fire-fighting equipment when a fire breaks out in a building, the fire-fighting water pump and the anti-smoke exhaust fan are related to the safety of life and property of the people in the building. And whether they can operate reliably, the control system is quite critical. At present, the control and protection functions of single or several fire-fighting equipment are generally only completed by individual control boxes, without forming a control system. In addition to primary components such as switching appliances, contactors, and thermal relays in each control, the control and protection functions are mainly composed of secondary components such as relays. [0003] For a fire-fighting equipment with a s...
