Embodiment 1

[0028] Such as figure 1 As shown, the precise positioning fire search and rescue robot includes a main control system (1), three GPS satellite positioning modules (2a, 2b, 2c), an attitude sensing system (3), a GSM MMS module (4), five A serial camera (5a, 5b, 5c, 5d, 5e), an environment detection system (6), a wireless data transmission module (7), a crawler drive mechanism (8) and a high-performance battery (9), characterized in that The main control system (1) is connected to the attitude sensing system (3) using RS232 to obtain robot attitude information, and the main control system (1) is connected to the three GPS satellite positioning modules (2a, 2b, 2c) are connected by RS232 to obtain three sets of GPS positioning information, and RS232 is used between the main control system (1) and the five serial cameras (5a, 5b, 5c, 5d, 5e) Connected to obtain environmental image data in the five directions of the robot, front, rear, left, right, and upper. The main control syst...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, especially in that:

[0035] see figure 2, the main control system (1) of the precise positioning fire search and rescue robot includes a main control microprocessor (101), and the main control microprocessor (101) is connected with a serial port expansion circuit (102), a power control A monitoring circuit (103), a communication interface circuit (104), a motor drive circuit (105), buttons (106), an indicator light (107), an SD card (108) and a reset debugging circuit (109), the main control The microprocessor (101) is respectively connected with the serial port expansion circuit (102), the power supply control monitoring circuit (103), the serial port interface circuit (104), the motor drive circuit (105), the button (106), the indicator light (107), The SD card (108) is connected to the reset debugging circuit (109), the serial port interface circuit (104) is connected to the serial port expansion circuit (102)...

Embodiment 3

[0046] As shown in Figure 3, the precise positioning algorithm is to obtain three sets of positioning information through the GPS module, and obtain the attitude angle information of the robot through the attitude sensing system. The horizontal projection triangle of the installation position triangle is obtained from the attitude angle information of the robot, two sets of credible positioning information are determined by comparing the normalized minimum error, and the precise positioning information of the robot is obtained through the calculation algorithm of the center of gravity of the triangle. The specific calculation is as follows:

[0047] (1) First, as shown in Figure 3(A), the fixed positions of the three sets of GPS positioning modules (2a, 2b, 2c) are triangle ABC (the length between the vertices of the triangle ABC and the angles of the three corners are fixed and fixed during installation. Measured), the attitude angle φ of the robot is obtained through the atti...

Abstract

The invention discloses an accurate positioning fire search-and-rescue robot. The accurate positioning fire search-and-rescue robot comprises a robot body, wherein a master control system, three global position system (GPS) satellite positioning modules, an attitude sensing system, a global system for mobile communication (GSM) multimedia message module, five series port video camera, a environment detecting system, a wireless data transmission module, a caterpillar drive mechanism and a high-performance storage battery are installed on the robot body. The master control system is connected with the attitude sensing system to obtain present multi-spindle attitude information of the robot. The master control system is connected with the three GPS modules to obtain three groups of positioning information, and the master control system is relevant to the attitude information, and accurate positioning information of the robot can be obtained through an accurate positioning algorithm. The master control system is connected with the caterpillar drive mechanism to achieve motion control of the robot. The accurate positioning fire search-and-rescue robot can be suitable for application of searching and rescuing under fire environment and the like.

Description

technical field [0001] The invention relates to the field of robot control, in particular to a fire search and rescue robot with precise positioning. Background technique [0002] With the continuous development of robot technology, search and rescue robots came into being. For the application of mobile robots in fire search and rescue, in order to improve the effectiveness and accuracy of rescue, the key lies in the precise positioning of the robot and the reliable feedback of environmental information. [0003] At present, most positioning systems use GPS positioning technology, but a single GPS positioning error is relatively large, with an error of about 5 meters, which is not accurate enough for search and rescue. [0004] Chinese utility model patent ZL 201020505319.7 discloses "a simple search and rescue robot". The robot can feed back the image information of the search and rescue robot, but it does not provide positioning information for the robot. The information ...
