Detailed Description
The core of the invention is to provide a data acquisition system, which does not need to set the data receiving address of the purchased terminal equipment by the staff, reduces the workload, saves the labor cost, can simultaneously carry out the storage control of the sensing data by a plurality of interface servers, and can improve the data storage efficiency.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a data acquisition system provided in the present invention, the data acquisition system including:
the plurality of terminal devices 1 are used for sending the acquired sensing data to the management server 2;
the management server 2 is used for respectively sending the sensing data to the plurality of interface servers 3 according to a preset distribution principle;
the interface servers 3 are used for storing the sensing data received by the interface servers to the storage system 4;
a storage system 4.
Specifically, in view of the technical problems in the background art as described above, and in view of the fact that if a plurality of interface servers 3 are directly used to receive a large amount of data of the terminal devices 1, although the efficiency of data storage can be improved by simultaneously performing storage control on the plurality of interface servers 3, due to the fact that the IP addresses of the plurality of interface servers 3 are different, the IP addresses of the target devices to which a large amount of terminal devices 1 need to transmit their own sensing data are not uniform, and the IP addresses of a large amount of terminal devices 1 must be configured one by a worker, which results in a huge workload, high possibility of error, and high labor cost, in the embodiment of the present invention, one management server 2 is provided between the plurality of interface servers 3 and the plurality of terminal devices 1, and the management server 2 can first receive the sensing data of all the terminal devices 1 in a centralized manner, therefore, at least the unification of the IP addresses of the data sending targets of the terminal devices 1 is ensured, and before the terminal devices 1 leave a factory, a manufacturer usually configures a default target device IP address for the terminal devices 1 in advance, so that when the terminal devices 1 are purchased, the manufacturer only needs to be informed of the IP address of the management server 2, and uses the IP address of the management server 2 as the default IP address of each terminal device 1, or after the terminal devices 1 are purchased, a worker directly configures the IP address of the management server 2 as the default IP address of each terminal device 1, and all the terminal devices 1 can smoothly send the self-sensing data to the management server 2, and the workload of a data acquisition system builder is reduced on the basis of not increasing the workload of the manufacturer of the terminal devices 1, thereby reducing the labor cost.
Specifically, considering that in a data acquisition system, the data volume of the terminal device 1 is usually very large, for example, hundreds of cameras may be used, and if the storage control is performed on the sensing data of all the terminal devices 1 through only one interface server 3, the sensing data is likely to be blocked and lost, the storage speed is slow, and the storage efficiency is poor, so that the embodiment of the present invention simultaneously sets a plurality of interface servers 3 to perform storage control on the sensing data, improves the data storage speed, and ensures that the data is not blocked and lost.
The number of the terminal devices 1 may be set autonomously according to the actual situation of the project, for example, the number may be 300, and the embodiment of the present invention is not limited herein.
Specifically, the number of the interface servers 3 may be autonomously set according to the number of the terminal devices 1, and in general, one interface server 3 may perform storage control on sensing data of a large number of terminal devices 1, so that the number of the interface servers 3 is usually much smaller than the number of the terminal devices 1, for example, the number of the interface servers may be 5, and the embodiment of the present invention is not limited herein.
The invention provides a data acquisition system, in the data acquisition system, each terminal device only needs to send the self sensing data to a management server, namely, only a terminal device manufacturer is required to set the default data receiving address of each terminal device as the IP address of the management server in a unified way when providing the terminal device, and a worker does not need to set the data receiving address of the purchased terminal device by himself, so that the workload is reduced, the labor cost is saved, a plurality of interface servers can simultaneously carry out the storage control of the sensing data, and the data storage efficiency can be improved.
