101/102/103（In the following description, for convenience, intelligent node is collectively referred to as, and is replaced with 100）In built-in one match
Put file（TSDS, Thing ' s SpecificationData Sheet）, this configuration file saves what the network element was connected
The various information of analog sensor（For example, the range of the type of sensor, sensor, the port numbers being connected with network element 100,
Data conversion rule used when carrying out sensing data encapsulation in the access device being connected with sensor etc.）.In network element 100
TSDS can provide a template file, when some port of network element 100 connects an analog sensor, be referred to template
Attribute information and port information of the write-in about this analog sensor in this TSDS.All the sensors connect complete with
And in TSDS after the write-in of respective sensor information, network element 100 can notice the sensing oneself connected to background system automatically
Device and information.
Use connection status of the current analog sensor in Internet of things system is as shown in Figure 3.Network element 100 is and simulation
The network access equipment that sensors A is connected with B (is previously referred to as intelligent node）, network element 100 include 2 modules：Analog-digital converter
（A/D converter）With protocol encapsulation module.Analog-digital converter is responsible for the analog signal that analog sensor exports being converted to number
Digital signal is encapsulated in network message by signal, protocol encapsulation module, is then transmit to background system.Protocol encapsulation module exists
When digital signal is encapsulated in network message, usually encoded according to certain data conversion rule, and background system is necessary
The real data of sensor could be parsed according to identical data conversion rule.And different producers is carrying out data turn
It changes and rule that when protocol encapsulation uses is all different, therefore, background system needs to obtain this data conversion rule.
Fig. 4 is the schematic diagram for reporting TSDS in the disclosure from network element to background system.
An as shown in figure 4, built-in TSDS file in the access network device 100 being connected with sensor.According to pre-
If the parameter for each sensor being connected with access network device 100 and corresponding data conversion is written in template in this document
Rule.After sensor and access network device 100 to be accessed to system and normally started, access network device 100 can be led
Trend background system reports sensor parameters and corresponding data conversion rule.
Above-mentioned flow is described step by step below：
Step 1 prepares each equipment, analog sensor, various auxiliary materials and tool before disposing；
Step 2, by analogue type sensors A and analogue type sensor B be connected to access network device 100 No. 1 port and

Ground configuration mode can write direct, update TSDS contents in access network device 100.
（ii）The mode of Remote configuration
It is established in the scene of connection in access network device 100 and internet, access can be remotely updated by internet
TSDS in the network equipment 100.Network element 502 can be computer, smart mobile phone or be special-purpose terminal equipment, pass through backstage
The TSDS in corresponding assembly update access network device 100 in system.
TSDS mechanism in above-described embodiment can allow user to reduce the configuration in deployment to the greatest extent, these configuration files can
To be just written when equipment produces or professional allowed to be configured.
For example, the possible coupled multiple analog that just can wherein prestore when access network device 100 dispatches from the factory passes
The property parameters of sensor need to only select the type of connected sensor when analog sensor is connected to access network device 100,
Its property parameters is just automatically write in TSDS files, at the same record the analog sensor connection port information, in this way may be used
To be substantially reduced the workload of configuration, and configuration work is placed on the access network device nearest with analog sensor and also may be used
With the probability of misconfiguration.
It will appreciated by the skilled person that realize that the whole of above method embodiment and part steps can pass through
The relevant hardware of program instruction is completed, and aforementioned program can be stored in a computing device read/write memory medium, the journey
Sequence when being executed, performs step including the steps of the foregoing method embodiments, and aforementioned storage medium can include ROM, RAM, magnetic disc
With the various media that can store program code such as CD.
