Description
Technical field
The present invention relates to warning systems, and in particular to a method of short message is sent by virtual short message cat.
Background technique
For the reliability and stability for ensureing types of applications business, each service server is deployed with all kinds of warning systems,
For when server, business software exception, instant early warning.At present on the market mainstream alarm be usually used sound, light, short message,
The modes such as mail；Wherein sound, light alarm are to reflect on the display being connected with server in real time, need someone's post in 24 hours,
It could find immediately；Mail alarm, which then needs to log in mail server immediately, just can collect and check warning information, and real-time is opposite
It is poor；It is also preferable that short message alarm is then not necessarily to artificial post, real-time, once system delay machine, sends an SMS to administrator immediately, pipe
Reason person can make emergency processing at the first time, so alarm mode is all based on short message alarm on the market at present.
Traditional hardware short message cat accesses application server, driving is installed, in the equipment manager-of application server "
Port can generate corresponding com port port numbers.Application server in a program-" short message cat configuration-" " communication interface ", selection
The corresponding port numbers of equipment manager, the baud rate of " traffic rate " selection short message cat, generally 115200；Short message cat is completed to set
It sets, application server can start to send short message.The work of short message cat is all based on AT instruction, when application server sends information,
AT instruction is first passed through, what brand detection short message cat uses, the short message cat of different brands, and communications command is different；Make
It is the mobile phone card of which operator, different operators sms center is different；The signal strength of current short message cat, signal is too
It is weak to send short message etc..After all communications status are all normal, application server will need the information sent to first pass through Bit7/
8 or UCS2 is encoded, and is instructed by AT+CMGS, the information that sends will be needed to be sent to short message cat, and short message cat will receive
Information transfers information to carrier network by gsm wireless network, and carrier network sends information to target mobile phones again,
To complete short message transmission.
But traditional short message alarm the drawbacks of also having its own.Its major drawbacks is as follows:
Every application server needs to develop corresponding short message cat interface, for sending short message.Currently, there is alarm on the market
The application software needed all supports that this is not main problem on 90%.Every server all needs a hardware short message cat, phase
When in everybody mobile phone used in everyday, for sending short message.Each server needs to spend the hardware expense of a short message cat.Each
The mobile phone card of the necessary operator of short message cat, so that each short message cat is monthly fixed to spend a Monthly Fee.Performance is unstable.
Current external short message cat is divided to serial ports and USB interface two classes, due to working mechanism, more than 10 days of general work will delay machine,
Needing could normal use after power-off restarting.And after delay machine, administrator is difficult to find immediately, and reliability and stability are poor.Short message
Cat processing capacity is poor, in high-volume transmission process, the upper limit is easily reached, thus delay machine.Short message cat short message is sent out every and sends one,
All need it is synchronous with operator, check short message whether send success, retransmit next, short message send speed to expire slow, low efficiency.Short message
It being sent for dispersion, amount is small, and short message expense can not decline, and every 0.1 yuan of short message rate.Note number disunity.Due to every service
Device all uses different short message cards, and the note number sent out is different from.It is limited by operator's base station signal, increase machine
The static radiation in room.Short message cat uses the wireless signal of operator, if will be unable to work without base station signal or dtr signal
Make；The transimission power of short message cat is generally 1-1.5W simultaneously, if a large amount of use, will increase the static radiation of computer room.Network peace
It is complete poor.Carrier network and enterprise network have virtually been got through using short message cat, and can not have been increased between short message cat and enterprise network
Add any Prevention-Security equipment, there is very big security risk.Single carrier network.Since only one SIM card of short message cat is inserted
Slot, one carrier network of selection that can only be single can not switch over if carrier network failure.It cannot in high volume send out
Send short message.Due to the management of Ministry of Industry and Information and the limitation of operator, plain old telephone card cannot send short message on a large scale.Hardware short message cat
It using GSM or cdma wireless signal transmitted data, is influenced by weather, environment, base station distance etc., transmits unstable, easily interruption.
In addition, being to meet the extensive needs for sending short message there are also only a few service server, sent by customization short message
Module, by modes such as information Batch sending to carrier gateway, middlewares, thus solve short message cat easily crash, transmitting efficiency it is low
The problem of；But can its scope of application be only limitted to current server, and in addition server use must carry out secondary development, and two
Secondary exploitation is also limited by the factors such as software development environment, operating system.It can not be widely applied, secondary development is costly.
