Description
Technical field
It is specifically a kind of applied to environmental protection equipment information collection the utility model is related to wireless data transmission technology field
Gateway.
Background technology
Equipment universal at present is mainly wire transmission, and data are uploaded by Ethernet interface included or external PLC,
This way disadvantage needs to connect up, and equipment access is cumbersome.Another is external general transparent data acquisition terminal
(DTU) although way, this method realize wirelessly, but there are many problems, and 1. common apparatus performances are very different, it is difficult to
It is good to find technical grade stability, and can be fitted in environmentally friendly acquisition terminal switch board.2. since data are transparent transmissions, transmission
Process is easy to be intercepted decoding, is used for illegal purposes.3. and server is interactive communication mode, reduces the interior of server
Core operational efficiency occupies the downlink bandwidth of server, increases in equipment end quantity, and it is easy to appear clothes for the susceptible condition of Data Concurrent amount
The case where business device collapse.4. when GPRS connection states are bad, at all can not gathered data, loss of vital data can be made.
Utility model content
The purpose of this utility model is to provide a kind of gateways applied to environmental protection equipment information collection, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions：
A kind of gateway applied to environmental protection equipment information collection, include the power unit for power supply, master control ARM, antenna,
House dog, memory, SIM card and GPRS module, the power unit include sequentially connected AC-DC converter, DC-DC conversions
Device and LDO circuit, master control ARM are separately connected antenna, house dog, interface module, memory, SIM card and GPRS module.
Further technical solution as the utility model：The interface module is SP485 interfaces.
Compared with prior art, the utility model has the beneficial effects that：1. number inside gateway device active acquisition control cabinet
It is uploaded according to being packaged, reduces the load of server, reduce gprs flows.
2. data pass through device id encryption, it is not afraid of to be trapped and cracks.
3. gateway device will not lose data after poor signal or other reasons and server connection breaking.
Description of the drawings
Fig. 1 is the overall block diagram of the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Include power unit for power supply, master referring to Fig. 1, a kind of gateway applied to environmental protection equipment information collection
ARM, antenna, house dog, memory, SIM card and GPRS module are controlled, the power unit includes sequentially connected AC-DC conversions
Device, DC-DC converter and LDO circuit, master control ARM be separately connected antenna, house dog, interface module, memory, SIM card and
GPRS module.Interface module is SP485 interfaces.
The operation principle of the utility model is：1. gateway and switch board communication interface are assisted using the MODBUS RTU of standard
View, hardware interface use RS-485,9600,8,1 no parity check position of communications parameter.
2. gateway and server communication format
Frame data format：
Xx (byte, switch board address), 03 (fixed, command word), 14 (fixed, 20 bytes), xx xx
Xx ... xx (data, 20 bytes), xx xx (2 bytes, crc16 verifications)
Data packet format：
Data frame 1, data frame 2 ... data frame 11 (totally 495 bytes)
Each minute sends out a data packet to server
3. gateway is initiated the connection to server, once the registration packet of 52 bytes is sent out in connection at once.
Registration packet format is such as
Character string 1：No more than 10 bytes, producer's model description；Character string 2：No more than 8 bytes, MODBUS slave addresses；
Character string 3：Fix 11 bytes, sim card numbers；Character string 4：No more than 7 bytes, system retains；Character string 5：10 byte of firmware, net
Close ID.
The each byte of data packet can do XOR operation with 2 characters are decided through consultation in gateway ID, realize the encryption of data,
Since comprising key, only in connection, hair is primary for registration, entire communication process will not be sent out again, and the data of interception will not include close
Key.
4. the data of gateway acquisition control cabinet are temporarily stored in a manner of queue in operation caching (8k RAM), according to advanced elder generation
The rule gone out is sent one by one.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing in the equivalent requirements of the claims will be fallen
All changes in justice and range are embraced therein.Any reference numeral in claim should not be considered as limitation
Involved claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiment being appreciated that.
