Brief description of the drawings:
Fig. 1 is container remote online condition monitoring system integrated stand composition of the present invention;
Fig. 2 is container remote online status monitoring terminal hardware structure chart of the present invention.
Detailed description of the invention:
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, container remote online condition monitoring system of the present invention, comprise monitoring terminal,Server and application terminal.
Each monitoring terminal is deployed on corresponding logistics container, by wireless network (for example GPRS,3G or 4G) by sensor gather quantity of state transfer of data to server, user can by applicationThe status data of terminal real time inspection container.
The major function of server be to from application terminal request respond, obtain specificFile (or call carry out cgi script), then return this file or program execution result toClient.
For example, application terminal adopts PC, and its browser and server passes through HTTP(HTTP) communicate. In the time that a HTTP request arrives, server process order, startsSearch the document that browser asks and consign to browser at server end.
The browser of application terminal will be asked to server transmission of information by HTTP, and server receivesAfter information, information is resolved, need call corresponding cgi script according to the type of request. ServiceThe interface standard that device is observed cgi script passes to information by environmental variance or standard inputCgi script, cgi script extracts relevant information and processes accordingly, logical with html formatCross standard output by result return service device. After server inspection confirms that data format is correct, by resultReturn to the browser of application terminal. So far complete the mutual of application terminal and server end.
In container remote online condition monitoring system, the CPU of server can move built-in LinuxSystem, by configuration driven program, transplants ICP/IP protocol stack, embedded web server, compilesWrite the Software for Design that static html file, CGI file etc. complete whole system.
User's operation realizes by the browser of application terminal, and data storage, extraction and renewal etc. are mainWant affairs to realize at server end.
Application terminal sends service request to server, and server provides corresponding clothes according to this requestBusiness, when user's sign-on access, the data of registered monitoring terminal in reading database automatically, it is right to realizeThe real time access of monitoring terminal data arbitrarily. Web application provides safety and stability, easy operatingHuman-computer interaction interface, container state data can curve map or the mode of form show.
User can also realize by smart mobile phone application program the browse application of monitored data, with usePC is compared more convenient.
As shown in Figure 2, in the present invention, the concrete monitoring terminal adopting comprises processor module and differenceThe sensor interface module, network communication module, data memory module, the electricity that are connected with processor moduleSource module and peripheral circuit.
Wherein sensor interface module is provided with RS232 interface, the RS485 for connecting respective sensorInterface, GPIO interface, voltage signal interface, current signal interface and RJ45 interface.
Wherein, RS232 interface, RS485 interface are numeric types, and GPIO interface is switching value classType, current signal interface and voltage signal interface are analogue types, the former adopts 4~20mA markAccurate current signal; For the latter, user need to be converted into through modulate circuit the voltage letter of 0~3.3VNumber, the stand-alone interface that access monitoring terminal provides.
The processor that processor module uses is ARM9 framework chip, if model is that Atmel company producesAT91SAM9G20-EK chip, processor module and sensor carry out according to corresponding communication protocolTransfer of data.
Network communication module is provided with Ethernet interface and wireless communicaltion module access, and processor module canBy Ethernet interface or wireless communicaltion module access access Internet.
Data memory module comprises data random access memory and data nonvolatile memory, and the former providesOperating system space, the latter provides data space, and data memory module uses twoSDRAM chip; Data nonvolatile memory uses NANDFLASH chip.
Power module is responsible for 12V/DC is converted to+5V/CD ,+3.3V/DC ,+1V/DC, is itHe provides stabilized power source in unit.
For example, use JCJ10 intrinsic safety type digital hygro sensor to gather humiture, it adopts RS485Communication interface, adopts modbus digital communication protocol, can be used for the humiture in inflammable and explosive placeMeasurement.
ModBus agreement is a kind of bus protocol that is applied to industry spot, supports multiple physical interface,Most of ModBus equipment communicates by RS485 physical layer. ModBus is master-slave mode communication, only there is a main equipment in agreement, multiple from equipment (maximum 255) on a communication network,Each have unique reference address from equipment. ModBus has two kinds of transmission modes: ascii mode andRTU pattern, the data transmission efficiency of RTU pattern is higher than ascii mode, and industrial control unit (ICU) makes mostlyUse RTU pattern. ASCII transmission mode is used LRC verification, and RTU transmission mode is used CRC schoolTest. Master-slave equipment must communicate according to identical transmission mode and message transmission rate. In this realityExecute in example, the processor of monitoring terminal is ModBus main equipment, and sensor is from equipment, and both sides pressModBus agreement is carried out transfer of data.
And for example, use SHT10 sensor collecting temperature, SHT10 is that a kind of digital Temperature and Humidity passesSensor, the serial line interface of the digital interface criteria of right and wrong, and iic bus agreement is incompatible, instituteWith in Software for Design, need to use the GPIO interface simulation communication protocol of processor module. Can makeRealize by programming as embedded OS with Linux, (SuSE) Linux OS is except in substantiallyOutside core, also integrated abundant device driver, these device drivers are all can be according to realityBorder system need to be carried out cutting, and the namely configuration of so-called kernel can be by the side of configuration fileFormula, in conjunction with Fundamentals of Compiling, realizes sensor and processor according to the communication protocol of selected sensorThe data transmission of module. Like this, some sensors that do not meet the sensor interface of standard agreement also canTo access monitoring terminal of the present invention, be convenient to user and change according to actual needs dissimilar sensingDevice.
Above content is only that the present invention is conceived to example and explanation, and above-described embodiment is exampleProperty, can not be interpreted as limitation of the present invention, affiliated those skilled in the art to describeSpecific embodiment make various amendments or modification or supplement or adopt similar mode to substitute, onlyOtherwise depart from the design of invention or surmount this scope as defined in the claims, all should belong to thisBright protection domain.
