Description
Technical Field
The invention relates to the field of wireless communication, in particular to a remote control method of a fault indicator installation tool.
Background
The fault indicator is used as a device for indicating fault current, and can quickly position a fault section, thereby timely recovering power supply of a fault-free area and reducing power failure time and range. Then, the fault indicator needs to be installed on the power line to detect the short-circuit current characteristics to judge and indicate the short-circuit fault, so that the installation tool of the fault indicator is particularly important.
At present, the mounting tool of the fault indicator is mainly a mechanical trigger type mounting tool, but the mounting tool is difficult to mount and dismount the fault indicator, and meanwhile, a trigger switch can be triggered by mistake or failure due to various conditions, so that the mounting repeatability is increased. Therefore, the remote control function is added, the fault indicator is mounted and dismounted, and meanwhile, the probability of false triggering or triggering failure is reduced. The existing installation tool with the remote control function can realize the remote control of the electric installation tool in a wireless communication mode, but has the problems of difficult operation and high requirement on operators, and even if the existing installation tool with the remote control function supports the wireless remote control, the function of the remote controller is realized through special software and hardware design, so that the cost is high, and the research and development time is long.

The invention adopts the following technical scheme:
step 1: the total number of 24 memory units of the remote controller internal coding chip can be equally divided into 4 identifiable clock cycles by using an SI4460 radio frequency transceiver.
The common (containing fixed code and learning code) remote controller internal coding chip has 24 bit storage units and 8 bit synchronous code, each storage unit has 16 oscillation cycles. Wherein, the memory cell data "0" is represented as a high level of 4 oscillation periods and a low level of 12 oscillation periods; the memory cell data "1" is represented as a high level for 12 oscillation periods and a low level for 4 oscillation periods; the synchronization code is identified as high for 4 oscillation periods and low for 124 oscillation periods. Because it is difficult for the SI4460 rf transceiver to collect long and short level judgment data "0" and data "1", 4 oscillation cycles are synthesized into 1 clock cycle, each memory cell is divided into 4 bits, i.e., data "0" in the memory cell is analyzed by the SI4460 rf transceiver to be data "1000", and data "1" in the memory cell is analyzed by the SI4460 rf transceiver to be data "1110".
Step 2: the front 8-bit storage unit of the remote controller is used as a synchronous word of the SI4460 radio frequency transceiver, and occupies 4 bytes, so that the data alignment in the data processing process is ensured.
And step 3: the 9-16 bit storage unit of the remote controller is used as an address bit, 4 bytes are occupied, different remote controllers are used for being matched with different installation tools, and interference among the radio frequency remote control of the installation tools is prevented.
And 4, step 4: the 8-bit storage unit behind the remote controller is used as a control code, 4 bytes are occupied, and different instructions of the remote controller are set;
and 5: and enabling a specified installation tool to execute a specified action according to the address bit and the control code. Furthermore, the synchronous words, the address bits and the control codes in the steps 2-4 can be adjusted in byte number according to actual conditions, and the remote controller can be encoded according to a remote controller encoding mode through an SI4460 radio frequency transceiver.
The synchronous words are used for ensuring data alignment in the data processing process; the address bit is used for distinguishing the radio frequency interference simultaneously emitted by different installation tools in the control process and preventing misoperation; and the control code is used for ensuring that different instructions of the same installation tool are distinguished.
Compared with the prior art, the invention has the beneficial effects that: by using the method, the installation tool can be adapted to a common (containing fixed codes and learning codes) remote controller, the function of the remote controller is realized without special software and hardware design, and the method has the characteristics of simple operation, convenient use and strong adaptability; the method is carried out by modifying the instruction of the installation tool, different remote control instructions are easier to realize, the interference between radio frequencies is prevented, and the running accuracy is ensured.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, a flow diagram for implementing the method of the present invention is shown, and the specific flow is as follows: after receiving the pulse, the SI4460 radio frequency in the installation tool analyzes, identifies and stores the unit, confirms the synchronous word, the address bit and the control code after the completion, and controls the corresponding installation tool to execute corresponding action according to the address bit and the control code. Taking the encoding mode of the fixed code remote controller PT2262 as an example, as shown in fig. 2, one of the key commands of the remote controller is a press-fit installation command, and after being pressed down, the radio frequency sends out a pulse waveform, wherein the data content of the memory cell is "010011010101010111000000".
After the data is received by the SI4460, as shown in fig. 3, the memory cell data "0" is parsed by the SI4460 into data "1000" which is hexadecimal data "8", the memory cell data "1" is parsed by the SI4460 into data "1110" which is hexadecimal data "E", each two bits are treated as a byte, and the data "8E 88EE 8E EE 888888" is obtained after the processing.
After processing, as shown in fig. 4, the MCU takes the first 4 bytes, i.e., "8E 88EE 8E", as sync words to ensure data alignment during processing; the MCU takes the middle 4 bytes, namely 8E 8E 8E 8E, as address bits, so that interference generated when different installation tools send out radio frequency simultaneously can be distinguished, and misoperation is prevented; the MCU takes the last 4 bytes, namely 'EE 888888', as a control code to ensure that different instructions of the same installation tool are distinguished.
As shown in fig. 5, after the MCU processes the command, the installation tool performs a press-fitting process, and returns to the initial position after the press-fitting process.
The synchronous word, the address bit and the control code can adjust the byte number according to the actual situation, and the remote controller can be coded according to the coding mode of the remote controller through SI 4460.
