Embodiment Construction

[0014] The invention uses the CAN bus communication technology, uses the CAN bus as the information channel of each electric control unit of the fire truck, uses these electric control units as nodes on the CAN bus, and connects them in series to form an efficient fire truck control system. The CAN bus nodes of this system mainly include: cab display and control panel ECU (Electronic Control Unit, electronic control unit), left pump room display and panel ECU, right pump room display and panel ECU, main controller ECU, engine compartment ECU, Pump room ECU, etc. The whole system has the following characteristics:

[0015] 1) The status information, control information, and communication information of each electronic control unit in the system can be transmitted through the CAN bus, reducing the complexity of wiring and improving system reliability.

[0016] Using CAN bus technology, only two wires are needed to connect all electronic control units in series, which greatly re...

Abstract

The invention relates to a fire-fighting vehicle based on CAN bus. In this fire-fighting vehicle, main controller ECU, engine area ECU and pumping room ECU are respectively accessed into CAN bus as the nodes of the bus, main controller ECU is taken as the control centre of CAN bus, which receives data information from other nodes, responses for the data operation and process and controls the wholesystem. This invention put the CAN bus technology into the fire-fighting vehicle, which reduces the cost, improves the transmission efficiency and reliability, and has the advantages of easy to maintain and strong expandability.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a CAN bus-based fire truck. Background technique [0002] With the continuous advancement of fire truck technology, new functions and new equipment are constantly emerging, and there are more and more electrical equipment on the car, such as electronically controlled fire monitors, automatic foam ratio mixing systems, etc., and various display instruments are becoming more and more complicated. Higher requirements are put forward for the integrated wiring and interactive information transmission of fire trucks, but the traditional fire truck wiring adopts a single point-to-point communication method, and each sensor and actuator on the car must use wires with its related electronic control unit In this way, not only the wiring is complicated, the maintenance is difficult, but the reliability is also reduced. The aging and wear of the wiring harness will bring safety hazards, and ev...
