Problems solved by technology

[0019] Over the years, many companies and research departments have tried to use video, infrared, laser, vibrating optical fiber and other technologies to realize the detection and alarm of foreign objects, but the effect in practical application is not optimistic.
Because the above-mentioned technologies will have interference and limitations in the implementation process, for example: the vibration optical fiber is more seriously interfered; laser detection is greatly restricted by terrain conditions; video technology will fail in foggy and rainy days, and video technology can only distinguish The size of the object, but the general type of the object cannot be distinguished, which will cause many false alarms
Therefore, foreign object detection in railway pavement and other fields is still a difficult point so far.

Embodiment

[0111] One embodiment of the present application is an electronic geoskin for detecting rockfalls with a diameter greater than 20 cm on a high-speed rail base. Such as Figure 12 As shown, a total of 21 basic units 100 (represented by a rectangular frame) and an interface circuit 800 in 3 rows and 7 columns are used to form an electronic geographic skin prefab 900. The shape of the preform 900 is a rectangle with a length of 126 cm and a width of 60 cm. Wherein each basic unit 100 has a rectangular shape of 20*18cm.

[0112] Such as Figure 13 , the basic unit 100 is surrounded by a hollow grid-shaped frame 146 formed of fiberglass material, and the inside of the frame 146 is used to arrange the R-SpiNNaker chip 120 and the power supply and communication cables 110 . The frame 146 forms a grid border with a width of 3 cm and a height of 1 cm. The R-SpiNNaker chip 120 of each basic unit 100 is located at the intersection formed by the borders of the frame 146. The frame 14...

Embodiment approach

[0185] According to another embodiment of the present application, the CDC only includes the excitation signal line port (AEC) and the mutual capacitance input signal line port (ACC), instead of the self-capacitance signal line port (SCA), but the excitation signal line port (AEC) or Mutual Capacitance Input Signal Line Port (ACC) replaces the function of Self Capacitance Signal Line Port (SCA). In this case, the connection line group of the analog signal router according to the embodiment of the present application includes the excitation signal line (AE) and the mutual capacitance input signal line (AC), but may not include the self-capacitance signal line (ASC). Correspondingly, the switches (KAS1-KAS5, and KSC) for connecting the self-capacitance signal line (ASC) are not included in the analog switch matrix.

[0186] As yet another example, by opening or closing a plurality of capacitive port coupling switches corresponding to the same connecting line of the connecting li...

Abstract

The invention provides a geographic skin constructed on the basis of an R-SpiNNaker chip. The provided geographical skin comprises at least one prefabricated part used for being laid on the surface of an area; the prefabricated part comprises at least one basic unit; the basic unit comprises a chip and a sensing module, and the chip on the basic unit is connected with the sensing module; the chip comprises a capacitance digital converter, a computing unit, a digital router and a neural unit. The computing unit generates a first type of data packet indicating a trigger pulse for one or more neurons of a neural unit according to the capacitance value output by the capacitance-to-digital converter; the computing unit is coupled with the digital router, and the first type of data packet generated by the computing unit is provided for the digital router.

Description

technical field [0001] This application relates to the geographical skin constructed by the R-SpiNNaker chip, which is used to detect disasters such as rockfall and mudslides and other factors affecting traffic safety on the surface of large-scale areas such as railway tracks and highways. Background technique [0002] The original intention of the SpiNNaker project (see "Overview of the SpiNNakerSystem architecture" on IEEE-Journals&Magazines Volume 62, Issue 12, Dec.2013) hosted by Professor Steve B. Furber of the University of Manchester is to try to understand and simulate how the human brain represents and processes information of. SpiNNaker tries to simulate the brain behavior of mammals, and does not involve the simulation of sensory behavior of mammals, so SpiNNaker is a massively parallel multi-core pure digital computing system. It can contain up to 1,036,800 ARM9 cores and 7T bytes (bytes) of RAM, distributed in 57K nodes (chips) throughout the system, each node ...
