3. Checksum example
For example:#000000011504180808090022046518E990000C2
According to the above example, the verification method of the check code is as follows:

No	01	02	03	04	05	06	07	08	09	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25	26	27	28	29	30	32	32	33	34	35	36	37	38	39	40
Character	#	0	0	0	0	0	0	0	1	1	5	0	4	1	8	0	8	0	8	0	9	0	0	2	2	0	4	6	5	1	8	E	9	9	0	0	0	0	7	D
Hexadecimal	23	30	30	30	30	30	30	30	31	31	35	30	34	31	38	30	38	30	38	30	39	30	30	32	32	30	34	36	35	31	38	45	39	39	30	30	30	30	7D
Calculation Method	Checksum calculation: In sum of all hexadecimal values, the end byte is 0 23 + 30 + 30 + 30 + 30 + 30 + 30 + 30 + 31 + 31 + 35 + 30 + 34 + 31 + 38 + 30 + 38 + 30 + 38 + 30 + 39 + 30 + 30 + 32 + 32 + 30 + 34 + 36 + 35 + 31 + 38 + 45 + 39 + 39 + 39 + 30 + 30 + 30 + 30 + 7D = 800 (combined value end byte is 0)

 

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:
