Description

Development board parameters:

Base station board:

1.MCU model: STC11F04E.

Two433Mhz superheterodyne receiving module: SYN480.

3. low frequency wake-up transmit antenna.

4. output relay.

5. low frequency wake-up antenna voltage selection: DC 5/12V.

6. on board USB to TTL, to achieve communication, download procedures, power supply.

7. wake-up distance 1-3m

Remote control end:

1.MCU model: STC11L04E.

2.433Mhz transmission module: SYN113/115.

3. low frequency wake-up reception antenna x/y/z direction.

4. remote control keys.

5. download and communication interface (welding disc).

6.CR2032 button battery (seat),It is required that Shun Feng express no battery.

7. wake-up distance 1-3m

8. standby power 2ua.

9. encoding: Keeloq (software simulation HCS300/301)

10. programming language: C51.

Operation process:

1. the CR2032 battery is installed on the base station board, and the sending board is connected to the computer with Android mobile data line (or DC12V power is inserted).

2. receiving plateThe ideal location of the antenna is parallel to the receiving antenna (the furthest distance).

3. turn on the power switch, the base station board power is connected, the base station board starts to send the wake-up signal (the base station board 433 radio frequency preparation receives the remote control board return data waiting time is about 4S no data relay buzzer does not move), when the LF wake-up signal is sent, the Study indicator light is lighted once, the remote control board receives the wake-up signal, and the STC11L04E is awakened after the remote control board receives the wake-up signal. At the same time, through the 433M radio frequency transmission module single chip computer analog Keeloq data transmission 3 times, the transmission board will receive the data to decode, check the legitimate open relay, the buzzer ringing 1-3 sound, Study indicator light.

4. manual mode: base station board boot default automatic mode (interval 4S cycle sends LF signal), hold down Auto_Key button, then open.

Base station power supply, buzzer after a sound, loose hand change mode manual mode and automatic mode switching. ManualModel

The LF signal will not be sent automatically, and short press will be requiredAuto_KeyButton, send a LF signal once again, and then wait

The high frequency data will be received (waiting for 4S).

5. note: the reason why the base plate does not move after receiving the 4S is:

1). The distance of the receiver is far away (the board is a test board, the actual effect of the high frequency remote control is poor, the non commercial level is only used for testing, and it is not used to evaluate the performance of the test board. Of course, the low frequency correlation test is in line with the application and actual scope of the project. It is necessary to pay attention to the matching of the antenna resonant capacitance to further enhance the LF effect. " As a result, there is a step by step 32PF in AS3933Resonant capacitance).

2). Is the remote controller learning and learning again?

6. control general process: the remote control board is awakened - - > wake up after the analog coded 433M send - > - > the 433M receiving signal of the transmission board - > base station board check to receive the data is legality - - > to open relay output, indicator lamp, buzzer.

Delivery list:

1. the receiving board and the sending board each.

2.CR2032 button battery

3.125Khz sends one antenna.

4. schematic diagram, PCB diagram, source code sent by mail, take note of the memo mailbox.

Special attention:

1. please test carefully after receiving the test board. If the hardware is faulty or unsatisfactory, please contact the seller to solve it.

2.After the trial of satisfactionAsk the seller for the development board againSchematic diagram, PCB diagram, source code, once sent, it will not accept any return requirements, hope to understand! We must consider carefully before sending the data, so as not to cause unnecessary losses to you.
