Dual anti-collision system with bionic positioning and tactile perception functions

Abstract

The invention relates to an anti-collision system, in particular to a dual anti-collision system with bionic positioning and tactile sensing functions, which comprises a central processing unit (1) and a moving part surface (5). A central processing unit interface (2) is arranged on the central processing unit. The dual anti-collision system is characterized in that an ultrasonic transmitting sensor (3) and an ultrasonic receiving sensor (4) are arranged on the moving part surface (5), the ultrasonic transmitting sensor and the ultrasonic receiving sensor are connected with the central processing unit through the central processing unit interface (2), groups of optical fiber arrays (6) are installed on the inner layer of the moving part surface (5), and the optical fiber arrays are connected with the central processing unit through the central processing unit interface (2). The dual anti-collision system with bionic positioning and tactile sensing functions has the advantages that the probability of collision of radiotherapy equipment is greatly reduced; and since the anti-collision measuring accuracy and the measuring range of a moving part are improved, on the premise that the probability of collision is minimized, the treatment space is expanded to the utmost extent and a good foundation is laid for the treatment of patients.

Description

technical field [0001] The invention relates to an anti-collision system, in particular to a double anti-collision system with bionic positioning and tactile perception, belonging to the field of medical equipment. Background technique [0002] At present, there are mainly two types of anti-collision devices used in radiotherapy equipment: [0003] One is a mechanical contact anti-collision device. A certain number of blocking wires are placed in places where collisions are likely to occur. When a collision occurs, these blocking wires will be stretched. The stretching is measured by rotating the potentiometer to prevent further collisions. However, these retaining wires are inherently elastic, which leads to a decrease in the measurement sensitivity of the rotary potentiometer. At the same time, the measuring range of the retaining wires is limited, and it is impossible to monitor the possible collisions in all directions. Therefore this device practical effect is not good...
