The traditional heterogeneous data transmission system of industrial enterprises has poor performance. In order to solve this problem, the design of heterogeneous data transmission system of industrial enterprises based on fuzzy algorithm is proposed. The hardware of the system is composed of STM32F107RCt6 microprocessor, FLASH memory, AS32-TTL-100 wireless module and DP83848x chip, which realizes the hardware design of two node functions. The system software introduces the fuzzy algorithm to realize the data transmission function, including data source management module, data extraction module, data writing module, log management module and user management module. The design of heterogeneous data transmission system of industrial enterprise based on fuzzy algorithm is completed by combining software and hardware. Finally, enter the experimental part to test the performance of the proposed system and the traditional system. The experimental results show that the performance of the proposed system is better, further play the role of information data in production; improve system efficiency and anti-fault ability.

The traditional data services of prediction for emergency or non-periodic events usually cannot generate satisfying result or fulfill the correct prediction purpose. However, these events are influenced by external causes, which mean certain a priori information of these events generally can be collected through the Internet. This paper studied the above problems and proposed an improved model—LSTM (Long Short-term Memory) dynamic prediction and a priori information sequence generation model by combining RNN-LSTM and public events a priori information. In prediction tasks, the model is qualified for determining trends, and its accuracy also is validated. This model generates a better performance and prediction results than the previous one. Using a priori information can increase the accuracy of prediction; LSTM can better adapt to the changes of time sequence; LSTM can be widely applied to the same type of prediction tasks, and other prediction tasks related to time sequence.

PurposeThis paper aims to propose an automatic coating and fastening robot (ACFR) of space solar module (SSM) to solar panel substrate.Design/methodology/approachDescribes the detailed manufacturing process of space solar cell arrays (SSCA), and gives an ACFR for SSM. Designs an automatic coating and fastening mechanism and a control system. Furthermore, establishes the “zigzag”, the “umbrella” and the Voronoi‐based “ring” path models of the coating path using syringes.FindingsThe robot is effective for the bubble‐free manufacture of SSCA in nonvacuum environment. The robot with three coating path models can control the thickness of adhesive layer on the back of SSM, and the fastening force to the solar panel substrate with high productivity. The experimental results have proved the validity of this robot in the SSCA's manufacture.Practical implicationsThe robot as a novel industrial equipment can improve the product quality and the reliability of SSCA to a certain extent.Originality/valueThe robot has potential applications in the SSCA assembly. It will change the traditional handworking status in the future.

SUMMARYThis paper discusses about auto-laydown robot (ALR), which is applied to performing the laydown process of a solar module on earth. The robot consists of an adhesive dispensing mechanism, an auto-laydown mechanism, a pneumatic system and a control system. The method of gripping solar cells is described based on pneumatic technology. Meanwhile, a new method of controlling adhesive thickness and area during dispensing is proposed in this paper. The robot realizes the automatic laydown process of solar modules and can control the laydown pressure effectively. Compared with the manual method, the robot could control the dispensing volume and the adhesive area between solar modules and panel substrates, by means of experiments. The novel ALR greatly improves the laydown quality of solar modules and meets the lightweight trend of solar cells development.

A chaotic secure communication system via CSK modulation using a feedback controlled receiver is presented. The transmitter and the receiver are built with Chua's circuits. We successfully transmitted a single character between two computers using this system.
