Embodiment Construction

[0033] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on the specific embodiments and in conjunction with the accompanying drawings.

[0034] see figure 1 , is a schematic flowchart of a shared memory-based cross-device sensor data management method provided in this embodiment. The method includes steps S101 to S106, and the specific steps are described as follows:

[0035] Step S101: the user registers the sensor in the management device.

[0036] Among them, several management devices are set. Different sensors are suitable for different management devices. When registering a sensor, the user needs to select a suitable management device according to the type of the sensor. In this embodiment, the management device is a device main board. Due to the limitation of space and size factors, there will be many device motherboards connected to various sensors, and the motherbo...

Abstract

The invention discloses a cross-device sensor data management method based on a shared memory, and relates to the technical field of sensor management, comprising the following steps: a user registers a sensor in a management device; after receiving the registration information, the management equipment applies for a memory space and binds address information of the memory space with corresponding sensor information; when a user needs to access the data of the target sensor, inputting the name of the target sensor into the management equipment; and after receiving the name of the target sensor, the management equipment queries whether a homonymous sensor exists or not, and if yes, the management equipment acquires address information of a memory space storing corresponding sensor data and maps the address information to a user process. According to the invention, the sensor equipment is not required to be provided with an internet access for data sharing any more, an IP address is not needed, and only the sensor name needs to be provided when the sensor data is accessed, so that the problem of address conflict caused by excessive sensors is effectively solved.

Description

technical field [0001] The invention relates to the technical field of sensor management, in particular to a shared memory-based cross-device sensor data management method and device. Background technique [0002] Generally, sensor devices must rely on network interfaces when they want to interact with processing platform devices running Ros software architecture. That is, if multiple devices based on Ros software architecture want to form a complete system, they must be realized through the network. When there are a large number of sensor devices, the network bandwidth and IP address resources will become very tight, and the requirements for the number of device hardware network ports will also increase. In addition, multi-process communication is also based on network transmission, including a large number of data copies, and the data transmission efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to over...
