Picking robot sensor wireless transmission device and method based on Zigbee technology

Abstract

The invention discloses a picking robot sensor wireless transmission device and method based on a Zigbee technology. The device comprises a sensor, a signal conditioning module, a data sending module, a data receiving module, a robot control computer and a power module. Signals of an obstacle avoidance sensor, signals of a position sensor and signals of a pressure sensor of a picking robot are connected with corresponding I / O interfaces of the CC2430 data sending module through the signal conditioning module and are transmitted to the antenna end of the data receiving module through an antenna, information obtained by the antenna end is processed through the CC2430 receiving module, the information of the sensor are transmitted to the robot control computer through a serial port conversion USB circuit at last, and therefore wireless transmission of robot sensor signals is achieved. The picking robot sensor wireless transmission device and method can overcome defects of an existing apple picking robot sensor wire transmission system, replaces a wired mode by means of a wireless mode, and has the advantages of the ability to obtain information of the sensor accurately in real time, high anti-interference performance and good extensibility.

Description

technical field [0001] The invention relates to a sensor signal wireless transmission device and method of an agricultural fruit and vegetable picking robot, in particular to an apple picking robot sensor wireless transmission device and method based on Zigbee technology, belonging to the field of agricultural informatization. Background technique [0002] my country is a large agricultural country, and it is an inevitable trend of social development to realize the modernization, mechanization and intelligence of agricultural production. Fruit picking is the most time-consuming and labor-intensive link in agricultural production. It has high costs, strong seasonality, and requires a large amount of labor and high-intensity work. However, due to the rapid development of industrial production, the diversion of a large number of agricultural labor force and the aging of the population, the labor force capable of engaging in agricultural production has become less and less, and ...

Problems solved by technology

At present, most of the fruit picking robot sensor signal transmission adopts the wired transmission method, which mainly has the following disadvantages: (1) Since the robot sensors are distributed in various parts of the robot, and the position of the main control computer of the robot is fixed, when the robot picks fruit, Some sensor signal transmission wires will inevitably come into contact with obstacles around the fruit, reducing the life of the wires; (2) Due to the messy sensor signal transmission wires, it is not conducive to maintenance after failure; During the telescopic process, the sensor signal transmission wires on the end effector are easily torn off
