v + is positive power supply;

v-: the power supply is negative;

GND: the data GND and the input detection port share a common ground wire;

TX/B: data transmission: the delivery outlet, the data receiving foot that connects user equipment notes: if the communication is RS232 communication, the cable is used as TXD, and if the communication is RS485 communication, the cable is B line of 485 line;

IN 2: an input detection port 2;

IN 3: an input detection port 3;

IN 4: an input detection port 4;

IN 5: is input into the detection port 5.

Specifically, the indicator light module includes:

power: red, power indicator light;

and (4) Net lamp: green, network signal indicator light;

run lamp: yellow, run status indicator light;

in DTU mode:

no flash or rapid flash: the device is not connected to the central server;

slow flash, the device having connected to the central server;

short message machine, alarm mode:

when the system is started, the yellow lamp flashes irregularly to indicate that the DTU module is initializing, and when the red lamp does not flash, the DTU module is initialized and enters a normal working mode;

in the operation process of the DTU module, when the yellow light flashes, the DTU module indicates that data is wirelessly exchanged and does not light up the table to be idle.

Specifically, the DTU module realizes the functions of 4G/3G/2G wireless internet access and data transmission through the wireless communication module; the short message receiving and sending module is used for sending and receiving short messages.

Specifically, DTU module electric connection has power module, power module's supply voltage: DC (5V-36V); the DTU module is also connected with a user cache module and is used for providing 30K user data cache.

The DTU module supports two protocols of a TCP/IP protocol and a UDP protocol (default TCP/IP);

heartbeat-network connection security mechanism:

in order to ensure that the connection link is a long connection and a stable connection without disconnection, the DTU module provides a set of complete link safety mechanism:

1. heartbeat mechanism

The DTU module can send heartbeat character string content to the center in fixed time, the center server can return the content original state after receiving the heartbeat content, and the DTU module can filter the heartbeat content returned by the center server and cannot send the heartbeat content to a user serial port. (thus, the central server can monitor whether the DTU module connection is working normally)

The heartbeat interval time is in seconds, and the content can be customized. If the heartbeat interval is set to 0, no heartbeat is sent.

Note: if the user equipment has a set of heartbeat mechanism, namely heartbeat, the heartbeat time can be set to be 0, and the DTU module is not allowed to send the heartbeat.

2. Central server data timeout

The DTU module may monitor any data sent from the central server side. For example, the setting is 120 seconds, that is, the DTU module considers that within 120 seconds, at least one packet of any data (including heartbeat content) sent from the central server is received, and if no data sent from the central server is received for more than 120 seconds, the DTU module considers that the connection is faulty.

When the DTU module detects the fault of the connection path, the DTU module closes and disconnects the current connection path, and initiates a brand new connection to the central server again after about 5-6 seconds to ensure the normal connection path.

If the issued data is not to be monitored, the data can be set to 0, and the DTU module does not monitor the connection link any more.

3. Forced monitoring of external data

In order to prevent serious failures of the link, or some unpredictable phenomenon. So that the connection can not be correctly connected and communicated. The system makes a 15-minute forced communication monitoring mechanism at the kernel level. That is, the DTU module has at least one bidirectional data communication with the central server in 15-heart clock. If there is no communication within 15 minutes, the system will be forced to restart (equivalent to powering off the DTU module again and restarting). The user is advised to turn this function on to prevent some unexpected malfunction.

4. Security mechanism co-usage

The mechanisms can be started singly or jointly, and a user can select the mechanisms according to the actual situation.

If the user does not want to use any of the set of mechanisms, but sets up a set of own security mechanisms with the user himself, all functions can be turned off. When the user finds that the connection is abnormal, the DTU module can reinitiate a new connection by the following method.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
