Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of wireless remote controller comprises key groups 1, little process chip 2, infrared transmission module 3, piezo electric module 4, power storage control circuit 5, antenna 6.The input end of the little process chip 2 of output termination of key groups 1, little process chip 2 links to each other with wireless signal transmitting module 3, and wireless signal transmitting module 3 links to each other with antenna 6.Push button after the group 1, microprocessor chip 2 obtains a coded signal, launches with electric equipments such as control televisors by wireless signal transmitting module 3 and antenna 6.The utility model need not to use powered battery, and power supply is finished by piezo electric module 4 and power storage control circuit 5.Described piezo electric module 4 is piezoelectric ceramics PZT, i.e. lead zirconate titanate Pb (Zr, Ti) 0
3Its piezoelectric effect is strong, good stability.Piezo electric module 4 is installed on the below, position of key groups 1, and when the user pressed button, piezoelectric ceramics is under pressure, and the effect back is reciprocal to be out of shape, and constantly excite charge generation voltage on its pole-face, thereby the mechanical energy that will press piezo electric module is converted into electric energy.As shown in Figure 2, described power storage control circuit 5 comprises rectifier bridge BG1, filter capacitor C1, super capacitor C2, stabilivolt D1; The first ac input end AC1, the second ac input end AC2 of rectifier bridge BG1 inserted at the two poles of the earth of described piezo electric module 4 respectively, the dc output end V-ground connection of rectifier bridge BG1, another dc output end V+ links to each other with the negative electrode of filter capacitor C1 positive pole, super capacitor C2 positive pole, stabilivolt D1, the equal ground connection of anode of filter capacitor C1 negative pole, super capacitor C2 negative pole, stabilivolt D1, stabilivolt D1 two ends link to each other with little process chip 2, wireless signal transmitting module 3, to its power supply.
Because the electric flux that piezoelectric material to generate electricity produces has moment property, and positive negative electricity is arranged, and can't directly power to electron device.So power storage control circuit 5 transfers the alternating current that piezo-electric device produces to direct current by rectifier bridge BG1, filter capacitor C1 becomes level and smooth direct current with pulsating dc voltage, level and smooth direct current is super capacitor C2 power supply, utilize the electric power storage ability of super capacitor to provide operating voltage for Digiplex, the supply voltage that stabilivolt D1 produces super capacitor as mu balanced circuit is controlled in the required operating voltage range of microprocessor chip and wireless signal transmitting module, as 1.8V-3.3V.The design's storage and control circuit have characteristics such as the voltage output duration is long, magnitude of voltage is stable.
Power consumption is the key problem that can this type of passive 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 utility model, in order to allow piezoelectric material to generate electricity drive the wireless remote controller 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 wireless remote controller, 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.Under the situation that adopts identical piezoceramic material, can strengthen the mechanical deformation of piezoceramic material by strengthening the area of piezoceramic material, increase the output of electric energy, to satisfy the required electric energy of telepilot.
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 circuit 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.
