The present invention relates to a kind of small-sized data acquisition node server based on WLAN, belong to Internet of Things and electronic communication field, be applied to the real-time detection of family information.
Background technology
Along with the raising of people's living standard and the development of science and technology, people are increasing to the demand of Real-Time Monitoring home environment information, family information acquisition method based on PDA has perfectly solved this problem, yet we have faced the sensor information of disperseing is carried out this Focal point and difficult point problem of acquisition and processing in realizing this method.At first in the process of information acquisition, we have used multiple sensor, and the signal of these sensor outputs is also had nothing in common with each other, and for the efficient process information of energy, we need to integrate these Information Monitorings.When information was issued once again simultaneously, the encryption and the coding that also need information is carried out were processed, so that the requirement that these information conforms send.According to these problems, just be necessary to design one and can cross the device of being edited and sending is processed in the sensor Information Monitoring.
Summary of the invention
The purpose of this invention is to provide a kind of small-sized data acquisition node server based on WLAN, can collect the data that a plurality of sensors collect, and by the CPU of inside information is encrypted, edit, compress, store and sends.
The technical scheme that realizes the object of the invention is: a kind of small-sized data acquisition node server based on WLAN, comprise shell and installation circuit board in the enclosure, has the terminal module hardware circuit on the circuit board, this terminal module hardware circuit is by data collection processor, storer and wireless communication module form, data collection processor is by CPU, data reception module, display module and power module form, data reception module is connected with the input end of CPU, CPU is electrically connected with wireless communication module by wireless communicaltion module access, CPU is electrically connected with storer by memory interface, display module is connected with the exit point of CPU, and power module is data reception module, CPU, wireless communication module and display module provide power supply.
Display screen and pilot lamp are installed on the shell, and display screen and pilot lamp are electrically connected with display module by wire.
Have the USB interface and the power interface that connect memory device on the shell.
Data reception module is divided into wired reception and wireless receiving two parts, wireline side comes the signal of receiving sensor as wired receiver module of core take RS232 and RS485, wireless portion comes the signal of receiving sensor by the wireless serial module, and the signal from sensor that data reception module will receive is transferred to CPU and processes.
After adopting technique scheme, the present invention is divided into three parts of data collection processor, storer and wireless communication module (network interface card/wireless module) in function, is responsible for respectively reception and processing, the storage of information and the forwarding of information of information.By the wireless receiving module on the node server information that sensor collects is received, again the information that collects is passed to CPU, by CPU information is compressed, edited and encrypts.The information that collects simultaneously can also be saved in the storer of node server.After CPU processes information, near the wireless access point AP editor's information can be transferred in the mode of WLAN by the wireless communication module on the node server (network interface card/wireless module).By edit and storage and the forwarding of this small-sized data acquisition node server to the sensor Information Monitoring, to realize that sensor makes the more efficient operation of whole system to the communication of user terminal in the whole system.
