If the application industry changes, it is only necessary to change the business processing process and display the UI interface for a long time, so as to achieve the purpose of quickly developing a high-quality monitoring system big data platform in the short term.

Example 2:

EMC Data Service Cloud Platform Project Network Communication Protocol

1. Design requirements for set-top box terminals and networks

1, can provide a safe channel.

Register the connection by verifying the device number and mobile phone number of the set-top box;

Data communications are tamper-proof and require data encryption.

2. The configuration software of the acquisition card can configure the acquisition frequency, upload frequency, server IP, port, threshold, etc.

The server can modify the parameters of the sampling card (such as upload frequency, server clock).

3. It can carry out emergency alarm for data exceeding the threshold.

4. In order to ensure the reliable transmission of data, a confirmation mechanism is used for communication with the server.

5. Reserve SMS channels, including configuration and active alarm functions.

6. The collected data is stored locally and the data that has not been sent successfully within a day will be sent first when the network is idle (60 pieces are sent one by one, and a group is sent at an interval of 29 seconds) or the device is restarted. (The boiler burner is divided into two states: working and standby, and the standby state can be regarded as the idle period of the network). Standby state: the start signal (in the real-time control system, the burner status byte is greater than 0) is invalid.

Standby state: 1 minute (fixed) to send a normal data, and then every 29s to send a group of 60 (one by one) to store the local lost packets. Abnormal data is sent every 5s.

Working status: 60 pieces of data are sent one by one in 5 minutes. If the data is not sent for less than 5 minutes, it will be stored when the data is lost.

7. Transmission mode: UDP/TCP transmission mode can be configured through the host computer software.

2. Network communication protocol

1. Operation Definition

(1) Configure the set-top box terminal

On-site configuration is carried out through the serial port and the host computer software supporting the terminal before leaving the factory. Configuration parameters: sampling frequency, upload frequency, server IP or domain name, port, UDP/TCP transmission method, threshold, SMS number (owner, 3 numbers can be preset), set-top box number and GPRS card number.

Support online configuration, configuration parameters: server time (regularly registered once a day at 3:00 am to synchronize the time of the server and terminal), normal data upload frequency (range: 1Min ~ 5Min), sampling frequency (range: 5s ~ 1Min), threshold.

(2) Communication process with the server

Registration process: After the terminal is powered on, it actively sends a data packet to the server, which contains the terminal's device number, GPRS card number, and device number. After the server receives the data, it replies a data packet to the terminal, and the data packet includes: the server synchronization time. The terminal uses this data packet to synchronize the time and determine whether the channel is established.

Registration process: that is, if the connection channel is not established, it will be sent every 5s. If it fails 5 times, the registration process will be restarted every 1 hour.

Initial installation/restore to factory settings: Data will not be collected until registration is successful.

After registration once: After the device restarts, the registration process is initiated again. Each time a group of 60 frames of data is lost, the registration process needs to be restarted, but data needs to be collected at the same time.

After successful registration, the indicator light is displayed (red/green). Network indicator (green monochrome), power indicator (red monochrome).

Note: After each power-on, you need to register once.

Normal data communication: The device is factory default, the terminal collects data according to the collection frequency (every 5s), and uploads data one by one (60 pieces) according to the upload frequency (every 5 minutes), and the server replies to the piece of data after each piece of data received. . For the data that has not received a reply this time, it is stored in the local Flash. Special situation: When there is no network service, 60 pieces of collected data are stored in Flash every 5 minutes, and only one day's upload failure measurement values are stored in Flash.

Alarm data communication: When the data collected by the terminal exceeds the set threshold, the data will be uploaded immediately at the next collection frequency (every 5s), and a high priority will be set; Send a text message to the owner when the alarm starts). When the alarm is eliminated, a normal data is collected and uploaded to inform the server that the alarm state is eliminated, and a short message is sent to the owner at the same time. (The data conversion will not alarm within 5 minutes) Note: If the alarm value fails to upload, it will be treated as upload failure data. When the alarm occurs, if there is still data (less than 60 pieces of data) that has not been uploaded before the alarm time, the system will automatically store this part of the data in the local Flash, and treat it as the upload failure data. The server acknowledges the alarm data.

Upload failed data processing:

After the device is restarted, all data in the Flash is uploaded through the channel initialization process established before; the upload time interval is 29 seconds. When it collides with the standby time interval, the normal data packets during standby are given priority.

Upload using idle time: collect data every 1 minute in idle time, and upload the data in Flash every 29 seconds. During this period, all data is retransmitted only once.

Re-registration process: When the registration is invalid or the terminal is not registered, the server can send a re-registration frame to request the terminal to re-register after receiving the collected terminal data.

(3) Encrypt data

In order to prevent data from being tampered with, the transmitted data needs to be encrypted, and the encryption algorithm is the TEA algorithm. Encryption only encrypts the data field.

2. Data frame format

Note: The data transmission adopts the big endian mode, that is: the high byte is in the front and the low byte is in the back.
