As shown in Figure 3, the interface signal of ZBTSRAM is primarily of compositions such as clock signal, control bus, address bus and data/address bus.Wherein, clock signal clk_zbt operates in interior various operations provide drive singal for ZBTSRAM realizes comprising reading and writing.Control bus forms primarily of three kinds of signals, and we_n is that read-write controls, we_n=1 allows read operation, we_n=0 allows write operation.Bw_n is sync byte write enable signal, and each byte has oneself effectively writes enable low level.Ld_n is address control signal, and during ld_n=0, the depositor of inside loads new address, if at the rising edge ld_n=1 of clock, internal address counter increases.Address bus addr is for providing memory address address signal to ZBTSRAM read-write operation memory cell, and its figure place is determined by the memory capacity of ZBTSRAM; Data/address bus dq is that ZBTSRAM carries out the passage of exchanges data when read-write operation with outside.
External processing unit adopts B/S(Browser/Server) structure, this structure is realized by the Core Feature part of system being focused on server, simplify the exploitation of system, maintenance and use, user side, without the need to installing any client software, only need have a common Web browser and namely access human body monitoring device by Internet.
Design the system components workflow diagram such as embedded web server, CGI function script, distance host end web browser as shown in Figure 2:
1. client (PC) logs in embedded web server by Web browser.
2. the CGI of embedded web server reads html web page to its buffer memory.
3.CGI sends the Web browser of webpage to client.
4.CGI is from the Shell of Linux, embedded data or read parameter driving.
5.CGI issues the Web browser of client after carrying out data conversion to the parameter read.
6., in client, the shell script (JavaScript, Python etc.) be embedded in webpage reads parameter and to the variable assignments of correspondence position on webpage, such webpage, by the position display parameter in regulation, ensure that the concordance of web displaying.
7. client sends new parameter to CGI by HTML list.
8.CGI receiving parameter invokes application, the parameter that application program obtains transfers to embedded OS by CGI scripting by the system function of embedded Linux system.
9. the parameter call driver that application program CGI transmits also finally controls Wireless physiological sensors.
The workflow of human body detection device is as follows:
1, human body monitoring device software
A, wireless sensor unit driver, wireless communication protocol stack.
B, external processing unit embedded OS, driver, man machine interface, embedded database.
2, using method and workflow
A, information gathering, wireless sensor unit gathers the human body physiological state such as blood pressure, heart beating information by Wireless physiological sensors, and after described status information being carried out pretreatment by micro-control module, stored in the first FLASH memory, transfer data to external processing unit finally by the first wireless transmitter module.
B, data receiver, the second wireless receiving and dispatching of external processing unit receives the data of wireless sensor unit 1 transmission, and transfers data to central processing module by universal serial bus.
C, date processing, central processing module processes further to data, finally stored in flash storage.
D, B/S structure, external processing unit 2 is by the same Internet connection of Network Interface Module, and user logs in external processing module by browser, after by user right certification, enters Human Physiology information monitoring interface.
E, except the mode in above-mentioned d, display module shows the physiological state information of human body in a dynamic fashion in real time.
F, historical information are inquired about, and except display real time status information, this monitoring device additionally provides the inquiry of historical data.
G, network self-healing, by the wireless communication protocol stack optimized, wireless sensor unit achieves the fault detect of network node and automatically replies function.
