Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Power consumption is the key problem that can this type of sun power telechiric device operate as normal, also is the difficult point and the focus of people's common concern in the design of electronic circuit system in recent years simultaneously.In the sun power telechiric device, in order to allow Driven by Solar Energy telechiric device circuit, it is imperative to reduce power consumption.And, when reducing power consumption, also can reduce the interference that electromagnetic wave causes miscellaneous equipment.

At the demand of the low-power consumption of this solar wireless remote-controlled device, can take following measures.For example each key is connected with the I/O mouth of microprocessor chip by the mode of directly joining in the keyboard, does not adopt traditional keyboard matrix, makes the remote control circuitry hardware simplicity.Present integrated circuit technology mainly contains TTL and CMOS two big classes, and no matter which kind of technology as long as there is electric current to pass through in the circuit, will produce power consumption.Usually, power consumption of integrated circuit is divided into quiescent dissipation and dynamic power consumption two parts.When the state of circuit did not overturn (keeping high level or low level), the power consumption of circuit belonged to quiescent dissipation, and its size equals the voltage of circuit and the product of electric current; The power consumption that dynamic power consumption is produced when being meant the circuit in the device being overturn, dynamic power consumption=electric capacity * voltage squared * frequency.Because present most of circuit adopts CMOS technology, quiescent dissipation is less, and what play a major role is dynamic power consumption.At wireless remote controller described in the utility model, can take technical measures to reduce power consumption from hardware and software two aspects.Hardware aspect can be selected the little filter capacitor of leakage current; The selection of stabilivolt should be used newer little electric current voltage-stabilizing device at present; Software reduces the power consumption aspect, reduces the full speed running time of CPU as far as possible, makes CPU enter idle mode quickly or the power saving mode is the key of dealing with problems.Can adopt the event driven program method for designing, when start, wake CPU up by interruption, allow it finish processing as early as possible at short notice to information or data, just enter idle power-down mode then, under off-mode, allow it enter power-down mode fully, it is waken up with regularly interruption, external interrupt or system reset.For the computing in the digital signal processing, can adopt FFT and fast convolution scheduling algorithm, this type of algorithm can be saved operation time in a large number, thereby minimizing power consumption, under the situation that precision allows, use simple function to replace complicated function to be similar to, also be a kind of method that reduces power consumption.During communication, can improve the baud rate of transmission as far as possible.Improve traffic rate, mean that call duration time shortens, in case communication is finished, telecommunication circuit enters low power consumpting state, and sends, receives and all should adopt the external interrupt processing mode, avoids adopting inquiry mode.The design of delay procedure has two kinds of methods: software delay and hardware timer time-delay, in order to reduce power consumption, use the hardware timer time-delay as far as possible, and the efficient of side's raising program reduces power consumption on the other hand.Use the reason of hardware timer time-delay as follows: most of flush bonding processors are when entering standby mode, CPU quits work, but and timer operate as normal, the power consumption of timer can be very low, when processor calls delay procedure, enter the standby mode, timer is started working, and the time is to then waking CPU up.CPU quits work and has reduced power consumption so on the one hand, has improved the operational efficiency of CPU on the other hand.

In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
