Embodiment
The first, the hardware configuration of this invention
The present invention is made up of central management device and one or more than one sub-controlled device.
1. central management device hardware configuration
As shown in Figure 1, the central management device hardware circuit of apparatus of the present invention can be divided into two parts: RF system circuit and baseband system circuit.Radio system is divided into again, radio-frequency transmissions part, radio frequency receiving unit and frequency generator.Shown in Fig. 2 dotted line block diagram.The effect of radio-frequency transmissions circuit is that baseband signal is modulated to high frequency and emission; The effect of radio-frequency (RF) receiving circuit is the high-frequency signal that receives to be separated be transferred to baseband signal, to make things convenient for microprocessor processes.Antenna part not only belongs to radio-frequency transmissions but also belong to radio frequency reception, i.e. duplexer.Frequency generator provides the stabilized frequency that needs for the radio-frequency transmissions circuit and the radio-frequency (RF) receiving circuit of central management device.The baseband system circuit function is to handle baseband signal, wherein comprises LCD display circuit, key circuit, SIM/UIM card circuit, power circuit, microprocessor and external memorizer or the like again.
A) RF system circuit introduction
The radio frequency receiving unit of central management device has adopted the double reception channel architecture.Reason is that the information that the central management device need receive is the emissive source from two different transmission frequencies.First receiving cable is to be used for receiving the note order that the user sends by the wireless network of operator, and the local oscillating frequency of demodulation of being used for of this moment is wireless communication frequency 900 megahertzes or 1800 megahertzes of China's regulation.And the second receiving cable is used for receiving the information that sub-controlled device is sent.Its local oscillating frequency that is used for demodulation then is the used frequencies of apparatus of the present invention, can not be identical with 1800 megahertzes with 900 top megahertzes.Temporarily be set at 450 megahertzes.So this two passes is to work simultaneously all the time, do not influence work mutually.
Introduce the course of work of double reception passage below.
No matter be, at first pass through the radio-frequency filter elimination radio noise of each receiving cable from user's mobile phone or the information that launches from sub-controlled device.Ensuing radio frequency amplifier (sometimes being called the high frequency low noise amplifier) is amplified to the signal that receives the degree that makes things convenient for the back device to handle.Elimination interference noise again.Because binary channels is worked simultaneously, sends if signal is a user mobile phone, then through the local oscillating frequency of 900 megahertzes or 1800 megahertzes radiofrequency signal is separated and is transferred to intermediate-freuqncy signal; If the radiofrequency signal that sub-controlled device sends is separated through the local oscillating frequency of 450 megahertzes so and is transferred to intermediate frequency.Through the intermediate frequency amplifier amplified IF signal, pass through the quadrature phase detector device again after, I is arranged, Q two paths of signals output.Wherein I is an in-phase component, and Q is a quadrature component.I, Q component are delivered to microprocessor and are handled through behind the analog to digital converter.Thereby finished the work of radio frequency receiving unit.
Because will be to user mobile phone and sub-controlled device emission short message or order, so the transmission frequency of central management device is also different.Microprocessor frequency control output interface sends the signal of control modulating frequency size to frequency generator.The note order that needs to send is all sent digital signal from baseband signal emission output interface.The baseband signal of launching under the suitable modulating frequency through the modulation after, transmit to different targets.If modulating frequency is 450 megahertzes, then to sub-controlled device emission control orders; When if modulating frequency is 900 megahertzes or 1800 megahertzes, at this moment to user mobile phone emission information.
Introduce the radio-frequency (RF) emission system course of work of central management device below.
Microprocessor is at first the baseband signal that will launch, from baseband signal emission output interface output digital signal.Simultaneously also will be to frequency control output interface output frequency control signal.If transmit to user mobile phone, then the modulating frequency sent of frequency control signal controlled frequency generator is 900 megahertzes or 1800 megahertzes; If transmit to sub-controlled device, the modulating frequency that frequency control signal controlled frequency generator sends is 450 megahertzes.After digital baseband signal then passes through digital to analog converter, modulate by the correspondent frequency that frequency generator sends.Through after filtering and amplifying, launch again via antenna.
B) the baseband system circuit is introduced
At first introduce microprocessor, because microprocessor is the core apparatus of baseband system, i.e. the brain of baseband system.The microprocessor that available similar mobile phone is used, for example ARM7.Function is as follows:
The first, it is responsible for a command format that the user's note command conversion that receives from radio frequency reception channel one becomes apparatus of the present invention to discern and to carry out.
The second, microprocessor is exported the order that will launch from baseband signal emission output port, and is partly launched by radio-frequency transmissions.
The 3rd, in baseband signal emission output port output digital baseband signal, also export the control signal of controlled frequency generator to the frequency control output port.
The 4th, the order that receives is deposited in the storer, in case sub-controlled system order does not run succeeded, can from storer, access this order and launch to sub-controlled system by the radio-frequency transmissions part once more.
The 5th, microprocessor is responsible for handling by receiving cable two and is received the information of coming.Do you judge that SIM card number mates? if coupling then handle is not if match then abandon.
The 6th, microprocessor receives the information that SIM/UIM card circuit sends by the SIM/UIM card.
The 7th, microprocessor receives by the information of key circuit to its input, and imports unique sign of each household electrical appliance to sub-controlled device by the radio-frequency transmissions part.Expanded the dirigibility of this invention so greatly.Controlled sub-controlled device can be added and delete arbitrarily, thereby controlled household electrical appliance can be added and delete easily.
The effect of LCD display circuit is the state that shows current household electrical appliance.The signal that it crosses microprocessor processes shows on LCD.Identical with the middle LCD display circuit of mobile phone.
The effect of key circuit is to central management device input information from the external world.It is the same with the key circuit of mobile phone.
SIM/UIM card circuit is also identical with the SIM in the mobile phone (GSM mobile handset card)/UIM (CDMA, WCDMA, TDS-CDMA mobile phone card) card circuit.
Because antenna circuit, LCD display circuit, key circuit, SIM/UIM card circuit, power circuit and frequency generator belong to matured product, apparatus of the present invention instructions is introduced their hardware circuit no longer in detail.
C) the command transfer form problem discussion between mobile phone, central management device and the sub-controlled device
(1) user mobile phone is to the command format of central management device emission
User mobile phone temporarily is set to the command format of central management device emission:
The appliance name seating position numbering execution time can be expanded project (for example temperature of She Dinging)
Wherein first three items is called the sign of sub-controlled device.The sign of each sub-controlled device is different, each sub-controlled device (linking to each other) with household electrical appliance be subjected to the central management device controlled before, write the unique identification of these household electrical appliance by central management device (being key circuit and radio-frequency transmissions circuit in fact) by the central management device to sub-controlled device.Form is as follows:
Appliance name seating position numbering
Why to add and number that? to prevent that a seating position is equipped with two identical household electrical appliance.After adding numbering, make this sub-controlled device have uniqueness.Basically by top form can be unique determine these household electrical appliance.
Whenever new household electrical appliances being arranged will be by the central management device management time, we can be used for distinguishing other household electrical appliance by the central management device to sub-controlled device input information.
If the user is incomplete to the order of central management device emission by mobile phone, the central management device is then reminded it to user mobile phone emission short message so.For example, the order of user's emission is:
No. 1 11:30 in air-conditioning parlor
The central management device judges that this order is imperfect, does not have design temperature.Then remind it to user mobile phone.Wait for the order that its emission is complete.
(2) the command transfer form between central management device and the sub-controlled device
Because apparatus of the present invention all adopt unified frequency of operation, if may exist work to disturb between not treated apparatus of the present invention more than two covers or two overlap.For example hypothesis has two cover apparatus of the present invention now, and label is No. one respectively, No. two.Take place to disturb is that No. one central management device firing order is given No. two sub-controlled device, makes its fill order.This should not occur.In order not make two covers or the above apparatus of the present invention work generation phase mutual interference of two covers.On order emission form, need between the sub-controlled device of central management device and its correspondence, add sign one to one.Because every central management device all will distribute unique SIM card number.At the central management device during, add the SIM card number of this central management device at the afterbody of order to sub-controlled device firing order.After the group controlled device receives order, judge earlier whether SIM card number mates, if mate then fill order, if do not match then abandon order.The group controlled device will add this central management device SIM card number at afterbody equally when central management device emission information.When the central management device receives information, also be to judge that earlier whether this information be the information that the sub-controlled device of its control launches, judge promptly whether SIM card number mates, if mate then handle it, if do not match then abandon it.
2. the hardware configuration of sub-controlled device
Sub-controlled device is the same with central management device hardware circuit can be divided into radio system part and baseband system part.As shown in Figure 3.
As shown in Figure 4, the RF system circuit of sub-controlled device.The receiving cable of sub-controlled device is different with the double reception passage of central management device, is single channel.Because sub-controlled device receives only the order that the central management device launches.Its frequency, demodulation frequency is 450 megahertzes.And the microprocessor of this moment does not need to frequency generator output frequency control signal yet.Because sub-controlled device only needs to central management device emission information, its modulating frequency also is 450 megahertzes.
Appliance control signal output interface bundle controlled device connects together with household electrical appliance.Sub-controlled device is exported control signal by this interface to household electrical appliance.
Other structures and central management device do not have any difference.
The microprocessor of sub-controlled device is the same with microprocessor in the central control unit, temporarily selected ARM7.Its function again with the central management device in microprocessor not quite alike.Function is as follows:
The first, handle the order that the radio frequency reception channel by sub-controlled device transmits.Judge whether it is the order that its central management device of control launches, judge that promptly SIM card number mates? if do not match then abandon, if coupling then be for further processing.If SIM card number coupling then, is the sign of the sign in the judgement order and these household electrical appliance of the storer in the book controlled device (when new household electrical appliance add this contrive equipment, having imported the sign of this electrical equipment through the central management device) mated? just do not abandon order if match; If coupling, microprocessor just become can control the signal of household electrical appliances to command conversion, and transmit to the appliance control signal output interface.
The second, call the data that exist in the storer and storing relevant data in storer.
The 3rd, to appliance control signal output interface output signal.
The 4th, to baseband signal emission output interface output digital signal or order.
The 5th, to LCD display interface output household electrical appliance status information and command execution status information.
Other circuit no longer are described in detail.
The second, software flow pattern
See Fig. 5 and Fig. 6 in the Figure of description.
