IoT Smart Meter

1. Meterings

This design uses the as the metrology computer. The TI Design TIDM is used as the stage of the metering component. The hardware and firmware are modified to feature relay control alighted to zero crossing.

2. Metering Data Access

This layout uses the HTTP Web Server at the CC3200 transfer statistics from the MSP430i2040 metering hardware. This transfer permits metering facts to be accessed using a web browser. The HTTP attendant listens on the HTTP socket (default to eighty) and then handles the request (HTTP GET ) by retrieving the internet web page files from the serial flash. The server then calls an HTTP event handler to operate on the variable contents. It then constitutes an HTTP reaction and sends a return to the purchaser over the Wi-Fi hyperlink.

3. Handling Dynamic Data Items

To allow the metering data to be examined with an HTML record with dynamic contents, the HTTP web server helps a hard and fast of predefined tokens to get replaced on the fly through the server with dynamically generated content. Some marks are predefined in the HTTP server with extra tickets that can be described in person software.

The HTTP server scans the HTML web page for the "__SL_G_" prefix. If the server finds a prefix, it tests the complete token. Once it matches a regarded token, it replaces the token inside the HTML with the ideal statistics (string) that suits that token. If the ticket isn't inside the predefined listing, the server generates a get_token_value asynchronous occasion with the token name. This request, in the end, calls to the HTTP event handler inside the most important. C code document. The handler interprets the symbol and responds to the token fee with a send_token_value. The HTTP net server uses this token cost and returns it to the customer. To ship statistics from the patron to the HTTP server, the server will check for the "__SL_P_" prefix. Then the server reviews the parameters list and checks every variable call to see if it fits one of the acknowledged predefined tokens. The server methods the values if the inconsistent names competition the predefined tokens. Suppose the HTTP internet server gets an HTTP POST request that carries tickets no longer inside the predefined list. In that case, the server generates a post_token_value asynchronous occasion to the host, which includes the following records: shape motion name, token call, and token price. The host can then system the specified statistics.

4. Implementation of HTTP Event Handler

To facilitate dynamic data, the consumer-described token is described for the set of information to be retrieved:

Go thru the Texas contraptions Wi-Fi link for the energy Monitoring document- http://www.Ti.Com/tool/TIDC-WIFI-METER-READING for a designated explanation of event coping with, hardware connection and to download the software program files; see the link above with name TIDC-WIFIMETER-READING. The software documents are distributed through the usage of a self-extracting executable record, which defaults to put into TIDCWIFI-METER-READING-SOFTWARE on the consumer's laptop.

After the hardware is attached, download the firmware to its corresponding hardware.

Once the relationship is carried out, you may reach the programming element. Set the Wi-Fi module to programming mode by switching the DIP to activate the Wi-Fi module to the ON function.

After loading the firmware and placing it up as described inside the link, you're equipped to test.

Test Setup

Look at the design and installation of the hardware loaded with firmware. Then practice AC voltage to the AC entry of the energy strip. And connect with it. Launch a browser and sort in the URL "mysimplelink.Net."The entire page may be proven with the meter's name in the upper left-hand nook (that is, "MSP430i2040 three SOCKET POWER STRI"). Then click on "Reading" to see the information.

There is no doubt about the ability benefits of smart metering. Intelligent meters are imperative for all market parties:

for metering organizations to decrease meter reading expenses;

for grid operators who want to put together their grid to the destiny;

for strength providers who need to introduce new, purchaser-made services and decrease call center fees;

for governments to reach strength saving & efficiency objectives and to improve free-market tactics;

for end customers to grow strength consciousness and reduce strength use and strength fee.

The introduction of intelligent metering appears additionally a logical step in a global where all verbal exchange is digitalized and standardized (Internet, E-mail, SMS, chat boxes, etc.) and where the price of 'digital intelligence' continues to be unexpectedly read. Moreover, then. The outcomes of intelligent meters on fitness aren't risky, according to many officers. Although research is going on everywhere in the world, people are reporting wireless is affecting their fitness.
