Problems solved by technology

Since the CAN bus has only one communication line, its collision probability is high, resulting in low efficiency of the communication line
At the same time, due to the round-trip delay in the transmission of the arbitration signal, the transmission rate of the arbitration signal cannot be too high, and the data transmission and the arbitration signal are transmitted on the same communication line, resulting in a very low data transmission rate of the communication line.
And the arbitration signal is transmitted through binary symbols, that is, through the symbols "0" and "1". Using binary symbols for priority arbitration, the arbitration efficiency is too low, and the queuing time of the equipment is long

Embodiment 1

[0037] Please refer to figure 1 , the neuron based on the robot perception system includes a control module, a near-brain interface, a cache queue module and several sensing interfaces, the sensing interface is used for connecting with sensors, and the near-brain interface is used for connecting with the central bus;

[0038] The control module includes an intelligent controller, two sets of arbitration controls and two sets of data transmission, the intelligent controller is connected to the near-brain interface through one set of arbitration control and one set of data transmission, and the cache queue module is respectively connected to the intelligent control device and two sets of data transmission connections;

[0039] It also includes at least one set of sub-arbitration buses and two sets of sub-data buses, the sub-arbitration buses and sub-data buses are respectively connected to the sensor interface, the intelligent controller is connected to the sub-arbitration bus t...

Embodiment 2

[0086] The difference between Embodiment 2 and Embodiment 1 is that the number of sub-data bus groups in the neuron is 4 groups, and at this time, the sensor sends four multi-ary symbol strings in one time slot.

[0087] The sensor that needs to send the data to be sent sends the multi-ary symbol string to the sub-arbitration bus for four consecutive times at the beginning of the time slot, and the time slot is the time interval required for the data bus to transmit a data frame;

[0088]The sensor that successfully sends the first multi-ary symbol string on the sub-arbitration bus will send the data to be sent to one of the sub-data buses at the beginning of the next time slot, and stop sending subsequent multi-ary symbol strings. The sensor that successfully sends the second multi-ary symbol string on the bus will send the data to be sent to another group of sub-data buses at the beginning of the next time slot, and the sensor that successfully sends the third multi-ary symbo...

Abstract

The invention discloses a neuron based on a robot sensing system. The neuron comprises a control module, a near-brain interface and a plurality of sensing interfaces; the system also comprises an arbitration bus and two groups of data buses. The multi-system symbol input by the sensing interface is compared with the voltage of other sensing interfaces, if the voltage amplitude of the multi-systemsymbol is higher than the voltage amplitude of other sensing interfaces, the multi-system symbol has priority, and the control module obtains a new multi-system symbol string according to the quantityof data to be sent and the weight of the multi-system symbol string; and successfully sending the sensor of the multi-system symbol string on the arbitration bus, and sending the to-be-sent data to the data bus. According to the neuron based on the robot sensing system, the wiring of the system is reduced, the conflict probability of the bus is reduced, the arbitration efficiency of the bus is improved, and the data transmission rate of the bus is increased.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a neuron based on a robot perception system. Background technique [0002] Since the concept of robot was proposed in science fiction in 1920, the field of robotics has experienced rapid development from scratch, especially in recent years, it has become a popular research project. Moreover, human dependence on and demand for robots in various industries continues to rise, and their intelligence is getting higher and higher. [0003] Taking humanoid robots as an example, humanoid robots are intelligent robots that can be similar in appearance and function to humans. As a highly intelligent creature, human beings not only have complex neural networks, but also have hundreds of millions of related neurons. In this regard, if a humanoid robot with excellent performance similar to humans is to be achieved, the complexity of the neural network to be implemented in the body...
