Network heartbeat packet mechanism

In order to ensure the reliability of the connection and check whether the device is online in real time, the device end will send heartbeat packet data to the service end every other period of time (60 seconds by default).

1.Data format (40 characters) of heartbeat packet sent by device side:
The data format of the heartbeat packet is the same as the above card reading packet, and the card number content in the packet is 0000000000.
For example: Chen 0331df00160227162357000000000000092

2. Data format of the confirmation package sent by the server (24 characters):
In order to keep the system time of the device consistent with that of the server, and automatically restart the device to reconnect to the network in case of system network abnormality (if the device automatic restart function is enabled), the server shall respond to the returned data after receiving the heartbeat packet sent by the device, and the returned packet data format is as follows:

Item	Head Mark	Command Code	Device Date	Device Time
Description	#	ACK	10 digit date character	8-bit time character
Example: #ACK 2015-05-09 08:14:08
