In order to make overhead transmission line ground wire mechanical vibrating deicing remote control percussion lock of the present invention can carry out operate as normal, described device also includes and is used for power module that other each modules are powered.
Also comprise the state display module 5 that is electrically connected with button control module 1, message processing module 2, radio frequency sending module 3 and power module respectively in the overhead transmission line ground wire mechanical vibrating deicing remote control percussion lock shown in Figure 1, be used for the operating state of display parameters configuration information and each module.
For processor, there is quite a few processor need use the equipment of SPI interface, in addition, whether the difference of SPI equipment and processor support each processor to have nothing in common with each other to GPIO mouth bit addressing, thereby software simulation GPIO also has nothing in common with each other in the different processor.If the driving with a kind of general configurable transplantable GPIO simulation spi bus then can be visited SPI equipment, thereby improves the reliability of whole embedded system.
The SPI interface is the serial line interface of a full duplex.It is designed to handle a plurality of interconnected main frames and slave on a given bus.In certain data transmission procedure, can only there be a rich machine can communicate by letter on the interface with a slave.In a data transfer, main frame always sends a byte data to slave, and slave is also always to byte data of main transmission.In the present invention, SPI interface circuit 4 can make MCU 201 and various ancillary equipment communicate with exchange message with serial mode.Because spi bus only needs 3～4 position datawires and control line can realize carrying out interface with the various I/O devices with spi bus interface function altogether, the expansion parallel bus then needs 8 data lines, 8～16 bit address lines, 2～3 control lines, therefore, adopt the spi bus interface can simplify circuit design, save interface device and I/O mouth line in a lot of custom circuits, save device resource.
In the communication network that constitutes based on the spi bus interface, communication can be initiated by host node, also can be by initiating from node.When host node was initiated communication, it can be initiatively to carrying out the data write operation from node.The course of work is as follows: at first choose to communicate by letter with it from node (usually sheet choosing end is for effectively low), then send clock signal, the operation of read data information will be carried out at the rising edge (or trailing edge) of clock.Whenever send eight clock pulse, produce an interrupt signal from node, this interrupt signal notice goes up the complete reception of byte of node, can send the data of next byte.SPI interface network principal and subordinate point need be finished and provide chip selection signal and clock signal, and it can be initiatively with respectively carry out exchanging of information from node; And under the situation that initiatively requires to serve from node, it but is a kind of form of half active.The network interface holding wire that constitutes by the SPI interfacing (CLK, MOSI, MISO ,/SS and INT) if be aided with corresponding complete communication protocol, its function must strengthen.
The SPI interface circuit is at two simple shift registers of the actual epipodium of internal hardware, and the data of transmission are 8, main device produce under device enable signal and shift pulse, the step-by-step transmission, high-order preceding, low level after.
Overhead transmission line ground wire mechanical vibrating deicing remote control percussion lock of the present invention in the course of the work, when data will send, MCU 201 writes nRF905 chip 301 by address and the valid data that SPI interface circuit 4 will receive the stage, MCU 201 is by being provided with TRX_CE, TX_EN transmits for the high Shockburst that activates nRF905 chip 301, nRF905 chip 301 is when carrying out transfer of data, at first finish powering on automatically of wireless radiofrequency transmission system, then to the packet prefixing with carry out CRC check, and then finish the transmission of packet, after transmission finishes, data ready (DR) signal is set for high, can proceeds the transmission of data; If AUTO_RETRAN is set to height, then to carry out constantly that data send until TRX_CE be low to nRF905.
The present invention adopts the nRF905 chip, and it has the following advantages:
(a) monolithic transmission.Simplify circuit greatly, reduced the use of components and parts, not only effectively improved the functional reliability of circuit; And dwindled volume, be that installation is used convenient.
(b) low-power consumption.Electric current is 12.5mA during work, and the holding state current sinking only is 100 μ A.
