Hereinafter carry out sending and receiving for message.The instant messaging of the mobile monitoring terminals such as final realization and Android intelligence.
The Software for Design of toxic gas diffusion monitoring system provided by the invention is specific as follows：
1st, the Zigbee wireless network softwares design based on Z-Stack protocol stacks
First, GenricApp routines are selected, create the engineering of oneself, change bottom to adapt to the hardware circuit of oneself.
The task ID of oneself is added in engineering, the event added in task mainly includes key-press event, wireless receiving event, serial ports and connects
Receipts event, the event of timers trigger, wherein the event generated using timer timesharing have gas concentration lwevel collection event,
Temperature acquisition event, humidity collection event, wind speed collection event, wind direction collection event, the transmission event of data, dormant event and
The detection of power supply and control event, in addition receiving node also to add a serial ports and send event.Serial ports is added in receiving node
Transmission event often receives the data that a terminal node is sent and just completes a serial ports transmission event.Complete bottom and task ID
Addition after, APP layers initialize serial ports, initialization timer, initialization power detecting and control program, and complete serial ports and
The setting of timer.Serial ports uses serial ports 0, wherein flow control is not selected, the 38400bit/s of baud rate selection acquiescence.Timer
Using the timer 3 of 8, operation mode uses Clear Timer On Compare, and channel pattern uses Output_
Compare compares output mode, sets and an Interruption is generated per 1ms, the cumulative of Count variables is realized in interruption, when tired
Just it generates a task events when being added to the value of setting, realizes timing acquiring data, timing transmission data, periodically into suspend mode,
A series of orderly work such as timing wake-up.The ID number of NV is set, and creates NV, opens nonvolatile memory, to preserve
The important information of the nodes such as the network information.
2nd, the data monitoring management Platform Designing based on QT
The signal of Qt, mechanism slot have been used in many places of writing of data monitoring management platform, are read including serial data, button
Event, slide bar event and drawing event etc..The signal of Qt occurs with slot with functional form, and the window member of Qt has much in advance
The signal of definition can add in signal by inheriting.When program starts to start, three sub-line journeys are created first, including master
Thread (processing interface operation), serial ports thread (receive data and handle) and TCP send thread and (send data to network service
Device).When serial ports has data arrival, the signal slot of sending/receiving data is touched, is handled data receiver and accordingly, and by number
According to storage to database.The data for being stored in database are just passed through TCP by program setting with JSON forms at regular intervals
Socket is sent to network service.
3rd, the design of server database
The information that this system is related to has：Nodal information, temperature, warning information, concentration of toxic gases, humidity.These letters
Breath can be retained in the database, as shown in Table 1 in the form of tables of data.
Table one：System information data table
| Field | Type | Description |
| Model ID | Char | Node serial number |
| Status | Byte | Alarm state |
| Temperature | Char | Temperature |
| Gas Concentration | Char | Concentration of toxic gases |
| Humidity | Char | Humidity |
Index technology can improve the speed of data query well.For tables of data, secondary index, level-one rope are increased
It is ID to draw, and secondary index is Status.When the relevant information for wanting query node, relative recording can be navigated to faster.This
Sample just improves the access speed of database.
4th, the network monitoring Platform Designing based on internet
System uses " server push " technology based on HTTP long connections, realizes that " server push " browser is sent out using AJAX
Go out XMLHttpRequest request, received server-side to request after, can blocking request until have data or time-out just return,
Browser JS sends out request again after processing request return information (time-out or valid data), re-establishes connection.In this phase
Between server end may there are new data to reach, server can select data to preserve, until re-establishing connection, browsing
Device can disposably fetch all data.
Client JavaScript response processing function can be after the information for having handled server return, and sending out again please
It asks, re-establishes connection.When client process receive data, re-establish connection when, server end may have new data
It reaches；These information can be preserved by server end until client re-establishes connection, and client can be once current server
Hold all information retrievals.
5th, Android mobile phone client monitoring application design
Android mobile phone client is established with network server and is connected, and the number that network server returns just is read after successful connection
According to.According to some parameter informations that network server returns, it is shown in the monitoring that data are carried out on interface.The software can be brushed periodically
New data and manual refreshing data, so when network server receives new data, cell-phone customer terminal end can timely update number
According to.
A kind of toxic gas diffusion monitoring method provided by the invention is realized based on above system, including terminal node, number
According to monitoring management platform, server, web publishing platform and client；Specifically comprise the following steps：Terminal node will detect
Poison gas environmental parameter be transmitted to data monitoring management platform；Data monitoring management Platform Analysis judges every poison gas environmental parameter
It is whether normal, it will analyze and determine that result stores to local data base and exports display；Data monitoring management platform will be analyzed simultaneously
Judging result is sent to server and carries out cloud storage backup, and web publishing platform and client are forwarded to by server, realizes
Multi-platform monitoring.
The present invention combines more monitor terminals, realizes to the long-range monitoring for a long time of target poison gas, accomplishes to give warning in advance, prevents thing
Therefore extension, support personnel, equipment safety.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformation can also be made, these are improved and deformation
