It should be noted that the customer information type that the method is obtained can be configuration information or state control information, control
Information processed is the information for controlling screen unit to be turned on or off, and configuration information is the equipment of screen unit to be carried out such as initialization
The information of the settings such as setting, parameter setting.
Specifically, after the step of judging information type S20, also include：
S60：If information type is configuration information, then configuration information to the screen unit is sent.
Specifically, judge after the step of whether state control information is timing control information S40, also include：
S71：If control information type is timing control information, the then timing control information that called data storehouse prestores；
S72：The timing control information is carried out into data encapsulation；
S73：Timing control information is sent to the screen unit.
It should be noted that described ought need control screen unit 300 to open default duration or need default
When time opens screen unit 300, then need to send timing control information, the timing control information needs called data
Data in storehouse, just can be with the control of completion timing.
Further, when data separate network is transmitted between different devices, in order to reliably and accurately be sent to purpose
Ground, and transfer resource (transmission equipment and transmission line) is efficiently utilized, packet is split and packed in advance,
Affix destination address on transmitted packet, local address, and some are for the byte of error correction, safety and reliability
When higher, to be also encrypted etc..These operations just make data encapsulate.And communicating pair when processing packet
The rule for following and consulting is exactly agreement.
Specifically, also including step：
S81：The status information of the screen unit is received, the status information includes that the switch of the screen unit is believed
Breath, geographical location information and warning message；
S82：The status information is sent to the client.
It should be noted that when status information is received, pushing it to client 110, checked for user, make user
The various information for obtaining each screen unit 300 promptly and accurately, the equipment safeguarded in time, adjust screen unit, it is ensured that system
The operation of stabilization, safety.
Specifically, the step of if not being timing control information, the screen unit is sent control information to S50 it
Afterwards, also including step：
S90：The record storage that information is sent is daily record.
It should be noted that so-called daily record refers to some operations of object specified by system and its operating result temporally having
The set of sequence.Each journal file is made up of log recording, and every log recording describes once single system event.Generally
In the case of, system journal be user can with the text of direct reading, wherein contain a timestamp and an information or
Other information specific to person's subsystem.
Journal file is highly important to system monitoring, inquiry, form and security audit.Record in journal file can
Following purposes is provided：Monitoring system resource；Audit user behavior；Suspicious actions are alerted；Determine the scope of intrusion behavior；
For recovery system provides help；Generation survey report.
