Description
Technical field
The present invention relates to a kind of wireless communication signals interference shielding system, especially for mobile phone wireless mobile in all kinds of classrooms
Signal of communication, short-distance wireless communication signal, WLAN communication signal implement the interference shielding system of interference shielding.
Background technology
Indication classroom of the present invention refer mainly to but be not limited to various kinds of schools for imparting knowledge to students, training, learn, examination etc. fixing or interim
Place.
Indication wireless communication signals of the present invention refer mainly to but be not limited to various technical standard wireless mobile communications signal (as GSM,
CDMA, WCDMA, CDMA2000, TD-SCDMA, 3G, 4G etc.) and work in various frequency and especially work in ISM band
Short-distance wireless communication signal and various technical standards WLAN communication wireless communication signals (as wifi, bluetooth,
ZigBee etc.).
Indication interference shielding of the present invention refers mainly to but is not limited to use the aforementioned defined channel radio of one or more technological means impact
The uplink/downlink signal of letter so that communication cannot be normally carried out.
With popularizing of smart mobile phone and developing rapidly of mobile radio network, class hour on classroom, by surfing Internet with cell phone, play trip
The student of play gets more and more, and causes teaching efficiency to be greatly affected.For this situation, each school, teacher take a lot
Measure, such as before class receives mobile phone, handset Wechat roll-call, disciplinary punishment etc., but these measures all produces little effect.
Solve the essential measure of this problem be at school the time implement wireless communication signals interference shielding in classroom, could thoroughly solve
Certainly student's online of upper class hour, object for appreciation this persistent ailment of game.
At present, cellular phone signal shielding device is very ripe and has obtained being widely applied very much, but cellular phone signal shielding device is school master
It is applied to all kinds of examination provincial, national.During use, open mobile phone shielding device and can produce interference signal, so that this
Region mobile communication cannot be normally carried out.
And classroom has class to need to carry out wireless communication signals interference shielding sometimes, and sometimes do not have class can not carry out wireless communication signals and do
Disturb shielding, so this mobile phone shielding device completely by user's Non-follow control is difficult to be directly used in the religion carrying out daily teaching activity
Room.Only in conjunction with course arrangement, can automatically carry out the wireless communication signals interference of wireless communication signals interference shielding in classroom
Shielding harness could meet the needs of daily teaching.So, classroom wireless communication signals interference shielding system should be fixedly installed in
Classroom and automatically start according to input to the course arrangement table of system or close interference shielding is carried out to respective wireless signal of communication, and
Do not need manual operation, also should be able to be set the operations such as input, modification simultaneously easily to the course arrangement table in system.
Some patents have carried out a few thing for the control of cellular phone signal shielding device.
Utility model patent " power supervisor of examination hall cellular phone signal shielding device " (Authorization Notice No. CN 202196281 U)
A kind of cellular phone signal shielding device power supply control method is proposed, in order to the power supply to the cellular phone signal shielding device used in examination hall
Automatically manage and control.The central contact of the relay of control system output control part exchanges confession with the A220V of manager
Phase line L of electricity power supply connects, and the phase line L end of normally opened contact cellular phone signal shielding device A220V communication power supply connects,
Under microprocessor control, obtain electric or dead electricity according to the control timer coil setting, thus correspondingly automatically open up and close
Examination hall cellular phone signal shielding device power supply.The keyboard being set by manager of test time manually sets.It follows that this
The power supervisor of the examination hall cellular phone signal shielding device mentioned by patent is applicable to the provisional mobile phone signal shielding being positioned over examination hall
The job control of device, and be not suitable for being fixedly installed in and carry out the classroom of daily teaching and automatically control by teaching arrangement time
The job control of wireless communication signals shielding device.
Utility model patent " a kind of cellular phone signal shielding device with management function " (Authorization Notice No. CN 203243337 U),
There is provided a kind of cellular phone signal shielding device with management function, mainly useful for solves multiple stage shielding device and uses management trouble simultaneously,
The high problem of management cost.The cellular phone signal shielding device with management function that this utility model patent proposes includes power subsystem,
Mobile phone signal shielding unit and radio management control unit.Radio management control unit is according to the control instruction control mobile phone receiving
The power switch of signal shielding unit, and the duty by mobile phone signal shielding unit is sent to manager, mobile phone signal shielding
Unit, then according to the command switch power supply of radio management control unit, is launched and mobile phone base after mobile phone signal shielding unit electric power starting
The downstream signal shielding mobile phone of same frequency range of standing.Not launching any signal after mobile phone signal shielding unit power-off, mobile phone is normal
Use.Thus realize artificially arrive on-the-spot just can the opening and closing of long-range managing mobile phone signal shielding, understanding equipment is real-time
Duty.The cellular phone signal shielding device of management function that what this patent was proposed have is applicable to the occasion of scope provisional, little,
And it is not suitable for classroom, one of reason is that radio management control unit is according to the control instruction control mobile phone signal shielding list receiving
All classrooms, if sending control instruction by wired mode to radio management control unit, must be connected by the power switch of unit
Becoming a network system, cost of investment is too high, infeasible.And if wirelessly sent to radio management control unit
Control instruction, then to pass through wall limited in one's ability for wireless signal, it is impossible to the transfer control instruction of all classrooms.The two of reason are, respectively
Classroom course arrangement has difference and the teaching of frequent every day to arrange different, uses to each classroom transmission control instruction abnormal numerous and diverse,
Not there is real operability.
Patent of invention " intelligent management system of mobile phone signal shielding network " (Authorization Notice No. CN 101115102 B), provides a kind of hand
Machine signal shielding network intelligent management system technical scheme, this management system can be by low-tension network to multiple mobile phone signal shieldings
Device realizes networking unified control and management.This system is applied to classroom and deposits problem both ways, and one is integrity problem, and two
It is that system complex investment is bigger.
In sum, current technology and related invention can not meet classroom is carried out wireless communication signals interference shielding application want
Ask.
