Technical field

The present invention relates to internet of things field, specially a kind of power distribution room things-internet gateway.

Background technique

Power distribution room is the key link for ensureing user power utilization reliability.With the development of technology of Internet of things, in power distribution room Controller switching equipment and its running environment on-line monitoring and control using more and more extensive.Due to on-line monitoring point a relative distribution, Electromagnetic environment interference it is larger, how to realize to all kinds of on-line monitoring sensors low cost access be urgent need to resolve the problem of.

Currently, power distribution room things-internet gateway generally uses following methods access on-line monitoring sensor:

Sensing data is transmitted to gateway by 485 cables by (1) 485 bus mode, such mode is reliable and stable, But there are constructional difficulties, disadvantage at high cost, and it is routed in some environments very difficult, or even it cannot achieve.

(2) small wireless mode, such as FSK, ASK scheme.The transmission range of both modes all farther out, but work frequency range In 315M, 433M frequency range, it is easy to be interfered, and power consumption is big, therefore be rarely used for industrial application.

(3) power line carrier (PLC) mode, i.e., access sensing data by power line carrier, and such mode can solve Exempt from wiring and signal problem through walls, but across the transformer communication of PLC is more complicated, and usually there are multiple transformers in power distribution room, because This may need to configure multiple PLC concentrators, increase communications cost.

In addition, the environment as locating for power distribution room is also varied, for example, in basement, independently of Office Area and living area Deng causing the communication of power distribution room things-internet gateway and background system also relatively difficult, if gateway only supports Ethernet or 4G Communication, may all encounter reliable communication problem in practical applications.

The main control module is connected with smoke sensor device, water sensor, temperature and humidity by 5 module by signal of bluetooth and passes Sensor, temperature controller are connected with metering ammeter signal；

The main control module is connect by plc communication module with the PLC concentrator signal, the PLC concentrator and institute Ethernet module is stated to connect with the 4G module by signal.

Preferably, the main control module using Freescalei.MX6D dual core processor (Cortex^TM- A9 kernel, Dominant frequency 1GHz), DDRIII 1066MHZ (1G memory), 4G-FLASH store core board.

Preferably, 5 module of bluetooth uses the Bluetooth chip CC2640R2F of Ti, works in 2.4GISM frequency range, is GFSK modulation, using FHSS frequency hopping, there is extremely strong anti-interference ability, communication distance maximum can also pass through up to 300 meters The mode of mesh networking extends communication distance, and networking number of nodes is up to 200~500.

Preferably, the plc communication module uses the broadband ARDCM PLC module, strong anti-interference, data transfer rate up to 2Mbps, Single-hop 1km, 15 grades of relayings.

Preferably, the data communication units and data acquisition unit are within the scope of same power transformer.

Compared with prior art, the beneficial effects of the present invention are:

1. this programme uploads the improvement of mode by the improvement to sensor data acquisition mode and to gateway, drops significantly Low site operation difficulty improves data acquisition success rate and data upload success rate under adverse circumstances.Specific manifestation is as follows:

2. using 5 agreement transmission sensor data of bluetooth, when site operation, is not required to be laid with the communications cable, and original is greatly saved Material cost and construction cost；

3. Bluetooth technology is that market is most widely used in Radio Transmission Technology, most mature technology, all wireless in the whole world In product, reach as many as 1/3 using Bluetooth protocol.The communication of 5 agreement of bluetooth is reliable, strong antijamming capability, moreover it is possible to pass through The mode of mesh networking keeps transmission range farther, even the equipment cabinet interior of installation, cable duct bottom, gateway can be reliable Receive data.Since bluetooth 5 communicates economic electricity, sensor is all battery power supply, can be non-maintaining continuous work 2 years or more.

4. using plc communication mode realizes that gateway data first passes to PLC concentrator, after then being uploaded to again by concentrator In the case that platform server, solving gateway installation site does not have a cable broadband, and 4G signal is also bad, also can reliably it upload The problem of data.It can be suitable for various power distribution room communication conditions, ensure the success rate that data upload.
