Embodiment Construction

[0028] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0029] Motion system unit: To control the front, rear, left, and right movements of the fire extinguishing robot, the DC servo motor is required to be able to achieve forward and reverse rotation, which requires the use of a reversible PWM system. The system is generally divided into two types of unipolar and bipolar drive. The unipolar drive means that the voltage of the armature of the motor changes in a single polarity (either positive or negative) in one PWM cycle. Bipolar drive means that in one PWM cycle, the armature voltage of the motor changes in two polarities (positive and negative). In comparison, unipolar drive is easier to implement, so the driver uses unipolar H-bridge mode to drive the DC servo motor. Such as figure 1 Shown is the motion...

Abstract

The invention relates to an intelligent early-warning firefighting robot based on embedded Linux. The intelligent early-warning firefighting robot comprises a motion system unit, an information collection unit, an early-warning firefighting unit, a network monitoring unit and a communication unit. The intelligent early-warning firefighting robot has the beneficial effects that the intelligent early-warning firefighting robot is based on an embedded linux operation system, the kernel is linux2.6, the period of system development is shortened greatly, and system operation is made more stable. A 32-bit ARM11 microprocessor S3C6410 is adopted for the system, various functions needed by control of the intelligent early-warning firefighting robot are integrated, and all modules of the system are based on a CAN bus for communication. Through the communication design of the early-warning firefighting robot based on the CAN bus, on the one hand, wiring and usage of components can be reduced greatly, the arrangement space can be saved for the inner firefighting robot, and meanwhile, the safety and stability of the whole intelligent early-warning firefighting robot system can be promoted.

Description

technical field [0001] The invention belongs to the technical field of public safety, and relates to an intelligent early warning fire-extinguishing robot based on embedded Linux. Background technique [0002] The research and development of early warning and fire-fighting robots in China began in the 1970s, and great progress has been made in the aspects of robot flame recognition, fire-fighting operations, and mobile technology. Generally speaking, there is still a certain gap with the level of foreign research. There are mainly the following problems: [0003] 1. The degree of networking is low, and a regional network system integrating early warning and fire fighting has not yet been formed. [0004] 2. The connection method of components needs to be improved. The automatic fire alarm system is mainly connected by multi-wire system and bus system, which limits the work of early warning fire extinguishers to a certain extent. [0005] 3. The automatic fire alarm syste...
