Two LoRa modules 101, the 2nd MCU102 receive the curtain control from mobile terminal by the 2nd LoRa module 101
System instruction, and the control instruction is parsed to obtain 201 address of the first LoRa module, and passes through the 2nd LoRa module 101 for curtain
Control instruction is sent to corresponding first LoRa module 201.The LoRa node 20 includes one the oneth MCU 202 and one first
LoRa module 201, the first MCU 202 receive the curtain from LoRa controller 10 by the first LoRa module 201
Control instruction, and curtain motor 50 is controlled according to the curtain control instruction and is worked, to realize the lifting of curtain.Preferably, originally
In embodiment, the input terminal of curtain motor 50 is connected with a relay 40, and the first MCU 202 is worked by control relay 40,
To control the work of curtain motor 50.
Because in LoRa technology, the communication between LoRa module needs two LoRa modules in the same channel, frequency, and
Know the address of other side, then before LoRa controller 10 is communicated with LoRa node 20, needs to LoRa controller 10 or LoRa
LoRa module in node 20 is configured (configuration including information such as frequency, channel and communication target address) accordingly, is matched
LoRa controller 10 can just forward information to corresponding LoRa node 20 or LoRa node 20 for its information after the completion of setting
It is sent to corresponding LoRa controller 10；The curtain setting one in each piece of region controls its lifting in this curtain Controller 1
LoRa node 20, the blind system is in building just by the 2nd LoRa module 101 or LoRa node 20 in LoRa controller 10
In the frequency of the first LoRa module 201, channel configured, when LoRa controller 10 receives the curtain control of user's input
When instruction, the curtain control instruction is parsed to obtain first in the LoRa node 20 that the curtain region that user to be adjusted is arranged in
The address of LoRa module 201 can be communicated.In the present embodiment, the 2nd MCU 102 and the first MCU 202 is based on list
The realization of piece machine, and in some other embodiments, chip can be controlled based on ARM etc. realize.It is of the invention based on above-mentioned design
Curtain Controller 1 is communicated using LoRa technology, that is, passes through the 2nd LoRa module 101 and LoRa in LoRa controller 10
The first LoRa module 201 in node 20 is communicated, and low-power consumption, low cost, the control of remote reliable transmission are realized, and
LoRa node 20 according to received curtain control instruction, that is, adjustable curtain lifting, it is easy to operate.
In the present embodiment, the 2nd MCU 102 is connected with one first display device 103, for showing curtain control
Instruction and the curtain lifting information from the first LoRa module 201.Preferably, in the present embodiment, the first MCU 202 connection

The curtain setting one in each piece of region controls the LoRa node 20 of its lifting, each piece of region corresponding one in the present invention
A number, and a corresponding LoRa node 20, LoRa wireless sense network run on the public metering frequency range of 470MHZ-510MHZ, tie
Time-division multiplex technology is closed, end-to-end communication collisionless in network is may make, maximally utilizes bandwidth, without back off time, with true
It protects to press the button and is not to cause the operation of motor 50 because of communication delay when switch 30 either inputs curtain lifting information
Network overall quality of service can be improved in delay, reduces network overall power, and the joint passage Frequency-hopping Communication Technology, ingenious land productivity
With different frequency hop sequences and channel network identification technology, intertexture Error Correction of Coding etc. so that network have it is very strong avoid in net,
The ability of outer radio frequency interference.
This curtain Controller 1 can both adjust the lifting of curtain by LoRa controller 10, can also pressing by setting
The lifting of the adjusting curtain of key switch 30.It, can be according to from movement i.e. when user needs to adjust the shade position in a certain piece of region
The curtain control instruction of terminal, the window of the corresponding number of curtain and required adjusting that the curtain control instruction is adjusted needed for including
Curtain goes up and down information (such as curtain lifting percentage etc.), and is shown in the first display device 103, and the in LoRa controller 10
Two MCU 102 parse curtain control instruction to obtain first in the LoRa node 20 that the curtain region that user to be adjusted is arranged in
The address of LoRa module 201, and curtain control instruction is sent to by corresponding first LoRa module by the 2nd LoRa module 101
The first MCU 202 in 201, LoRa nodes 20 judge number in received curtain control instruction whether with one's respective area pair
Answer, if not then abandon curtain lifting information, if then according to the curtain control instruction control from the first LoRa module 201 after
Electric appliance 40 works, to control the work of the motor 50, to control curtain lifting percentage, and curtain lifting information is sent
It is shown to the second display device 203.And in some other embodiments, when user needs to adjust the curtain position in several pieces of regions
When setting, then in LoRa controller 10 the 2nd MCU 102 parsing input curtain control instruction with obtain it is multiple number and its it is right
The curtain lifting information adjusted needed for answering to obtain the address of multiple corresponding first LoRa modules 201, and passes through second
Corresponding curtain control instruction is sent to corresponding first LoRa module 201 by LoRa module 101.Understandably, user can also
The lifting that curtain is adjusted by key switch 30, in the present embodiment, the first MCU 202 in key switch 30 and LoRa node 20
Hard serial ports connection, when short-press key, the first MCU 202 reads short-press signal, parses and sends window to relay 40 after the signal
Curtain standard-sized sheet or the operating instruction closed entirely；When long-pressing key, the first MCU 202 of LoRa node reads long-pressing signal, the
One MCU 202 persistently sends run signal to relay 40, and when key unclamps, the first MCU 202 of LoRa node, which is read, to be unclamped
Signal, the first MCU 202 sends signal out of service to relay 40, and curtain lifting information is sent to the first MCU 202
To be shown in the second display device 203, and curtain lifting information can be fed back to LoRa controller 10 and shown with showing first
On showing device 103.
In conclusion curtain Controller of the invention is communicated using LoRa technology, i.e., in LoRa controller the
Two MCU parse the curtain control instruction from mobile terminal, and the curtain region that user to be adjusted is arranged in acquisition
The address of first LoRa module in LoRa node, and curtain control instruction is sent to corresponding first by the 2nd LoRa module
LoRa module, the first MCU in LoRa node control curtain motor work according to the received curtain control instruction of the first LoRa module
Make, to realize the lifting of curtain, realize low-power consumption, low cost, the control of remote reliable transmission, and LoRa node according to
Received curtain control instruction, that is, adjustable curtain lifting, it is easy to operate.
