Description

Moving wheel type trolley based on arm electric signal control

Technical Field

The utility model relates to an industrial automation field especially relates to a moving wheel formula dolly based on arm signal of telecommunication control.

Background

The existing industrial robot is controlled by a console, controlled by computer software and controlled by a steering wheel, but does not use an automatic device controlled by muscle electric signals, and the former control mode is universal, but has a problem that the existing industrial robot needs to carry a control input device with small volume and cannot timely feed back the limit of the device, so that dangerous operation is easily caused. But muscle electricity signal controller belongs to wearing equipment, and the controller is very portable, easy operation, can reach spacingly with the mode suggestion user that feels moreover. The industry is still in the technological popularization stage at present.

The wireless communication modes comprise Wi-Fi, ZigBee, Bluetooth and the like, and lay a foundation for the interconnection of the automation industry. The development of artificial intelligence and the technology of the Internet of things promotes the intelligent industrial systematization, and the man-machine interaction mode is controlled by the traditional people and develops towards the automatic self-excitation induction and self-excitation feedback directions of the intelligent industry.

At present, an industrial personal computer becomes a main control terminal for industrial automation, and the intelligent industrial automation is controlled in a diversified manner in a control mode of a host and a network cable. With the improvement of intelligent automation equipment, an industrial personal computer serving as a control center in a transition period is gradually replaced by other more suitable portable control modes, and the existing logistics automation, intelligent illumination, quality detection and the like are developed towards intelligent industrial automation.

The existing intelligent logistics technology is as follows:

the intelligent logistics utilizes the inheritance intelligence technology, so that the logistics system simulates the intelligence of people, and has the capabilities of thinking, sensing, learning, reasoning, judging and automatically solving certain problems in the logistics so as to meet the requirement of industrial automation. And the safety and convenience of the logistics path are judged, so that the reliability of the logistics system is controlled.

The intelligent logistics system is also widely applied to basic activity links such as logistics transportation industry, transportation, storage, distribution, packaging, loading and unloading and the like through an information processing and network communication technology platform by utilizing advanced internet of things technologies such as bar codes, radio frequency identification technology, sensors, global positioning systems and the like, so that the automatic operation and high-efficiency optimized management of the goods transportation process are realized, the service level of the logistics industry is improved, the cost is reduced, and the consumption of natural resources and social resources is reduced. The Internet of things provides a good platform for the logistics industry to combine the traditional logistics technology with intelligent system operation management, and further can better and faster realize the information, intelligent, automatic, transparent and systematic operation modes of intelligent logistics.

The automatic logistics robot system has the advantages that manual teaching and testing links cannot be omitted in the process of achieving full automation, manual debugging of the logistics robot is needed before teaching and meeting automation logistics, the system is convenient to carry, and a controller which is simple to debug can stand out from numerous logistics robots.

The existing intelligent control feedback system:

the feedback system of the current mobile phone controller is mechanical limit, the limit is controlled by limiting the limit positions of a knob and a sliding block, buffering and critical reminding are generally not available, and the problems of mechanical error and zero setting are solved; software control has this more intuitive limit position, though there is no mechanical error, still needs zero setting. The system prompts an operator in a mode of software scanning or hardware detection and in a mode of screen or alarm, but alarm information cannot be timely received when the principle of the operator is that a software screen or environmental noise is large.

However, the wearable operating device can not only feed back the operating state visually or audibly, but also feed back the operating state by tactile sense. This is an innovative point that neither of the former two cannot do. And wearable equipment can be closer to by operating means more, can directly feed back to wearable equipment when being possessed spacing detector on by operating means, reminds the operator to reach spacingly through feedback modes such as vibrations to timely rescue equipment.

The function of the existing industrial robot is not practical and the gimmick is too many, which results in high cost. At present, industrial automation price is high, a system is complex and tedious, simple things are complicated due to low intelligence, an APP interactive operation mode is complex, and humanized thinking is lacked. The industrial automation is required to be used, the operation is carried out through a wearable operation and a control panel, the operation is actually more practical than a mobile station and an industrial control machine, the operation is simpler than the mobile station, and new staff in a factory still need to be familiar with the equipment and do not know how to use the equipment. Otherwise, the program is set and the machine is started regularly, and the machine is not uniform every day and cannot meet the requirement.

In addition, industrial machines of different brands are incompatible, and the industrial machines of different brands cannot be interconnected and intercommunicated, so that the intelligent effect is lost. Different machines in a factory are not necessarily manufactured by one manufacturer, because no standard exists to perform the manufacturing, which results in the inability to control different industrial equipment on one platform.
