Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises the MC13224 chip, the MC13224 chip connects sensor, display screen, accumulator and antenna respectively, described accumulator connects display screen, solar recharging managing chip and sun power pole plate, and the solar recharging managing chip links to each other with described sun power pole plate and MC13224 chip.
This node adopts the ZigBee wireless singlechip MC13224 of ARM kernel, this chip the is integrated ARM7 kernel of standard, 2.4GHz radio-frequency (RF) transceiver, IEEE 802.15.4 MAC hardware accelerator and AES hardware accelerator, built-in FLASH, SRAM and ROM, modules such as AD conversion, and up-to-date ZigBee 2007/PRO protocol stack is provided in development environment, can realize radio communication.Polymer storage battery 782338 is adopted in the power supply power supply, and accumulator is connected with solar recharging managing chip and sun power pole plate.Solar recharging managing chip CN3063 inside has 8 analog to digital converters, can adjust charging current automatically according to the fan-out capability of input voltage source, and do not need to consider worst case, can maximally utilise the electric current fan-out capability of input voltage source.The sun power pole plate ZT110*70A provide natural energy source for accumulator.Node is furnished with miniUSB(or USB simultaneously) interface, voltage by USB interface output also can be powered battery, during for special circumstances, as continuous overcast and rainy when occurring, can be when the battery reserve of electricity is lower than default definite value with the charging equipment of USB interface to the on-the-spot node battery charge of giving.Power-supply management system, the duty and the power supply situation of real-time monitoring battery, this exterior node has display screen SSD1303T9R1, and the OLED screen of 128 * 64 dot matrixs shows the information of being gathered in real time.
Sensor can have a plurality ofly among Fig. 1, is not limited to 3.Sensor is sent to the MC13224 chip with the physical message of collecting, by in the chip with the 12 bit A/D converters natural simulating signal that will receive, convert digital signal to as temperature, luminosity, humidity etc., from wireless transceiver circuit by antenna transmission to the PC of Surveillance center, this PC has corresponding wireless receiving module, perhaps another radio node module.Digital signal after will changing simultaneously is transmitted on the display screen by display circuit and shows.
The power supply of node such as Fig. 2, the input voltage range of solar recharging managing chip CN3063: 4.35V-6V, constant-voltage charge voltage 4.2V, constant-current charge electric current 500mA.Its voltage source is the power supply by the USB interface input, the power supply that another voltage source is changed for the sun power of collecting by the sun power pole plate.P channel mosfet pipe M1 is used for stoping electric current to flow into the second input power supply from the first input power supply, and schottky diode D1 can prevent that the second input power supply is by 1K resistance consumption energy.In actual applications, the first input power supply is received the sun power pole plate, and the second input power supply is received on the USB interface.When using two kinds of power supplys simultaneously, the first input power supply has right of priority.When being in charged state, the D2 lamp is bright; After charging was finished, the D2 lamp went out, and the D1 lamp is bright.The indication end of charging simultaneously directly drives the MC13224 port, by MC13224 chip monitoring corresponding port information, and with information by transmitting terminal, send to Surveillance center or node, and on display screen, show charged state.For guaranteeing good stable and temperature characterisitic, resistance R 5 service precisions that are connected port ISET are 1% metalfilmresistor.Resistance R 6 and R7 form the voltage that potential-divider network is realized the TEMP pin, and R7 is the PTC thermistor of a ceramic mould.The temperature detection of battery realizes by the voltage of monitoring TEMP pin, when the voltage of this pin surpasses 0.15 second greater than 46% of VIN, the chip operate as normal, when if the voltage of pin surpasses 0.15 second less than 46% of VIN, think that then the temperature of battery goes beyond the scope, charging will temporarily be stopped, and when the voltage of pin surpasses 0.15 second greater than 46% of VIN once more, charging will continue.The FB pin is received the anodal Bat+ of battery among the figure, can effectively avoid the influence of dead resistance to charging between anode Bat+ and the pin BAT, can not be unsettled.Employed battery (Fig. 2 right side square frame) nominal capacity is 1000mAh, thickness 7.8 ± 2mm, and width 28 ± 0.5mm, length 37 ± 2mm, model is 782338 polymer rechargeable cell.Maximum charging voltage 4.2V, nominal voltage 3.7V, charging current 500mA.
Power management module on Surveillance center's PC mainly is a Charge Management of realizing battery, and the pin voltage of the pin CHRG of monitoring charging management chip CN3063 and the pin voltage of pin DONE are judged the residing this moment state of battery from the height of voltage.Management process such as Fig. 3, at first the CHRG pin voltage A of detection chip CN3063 and DONE pin voltage B, the PC screen display of Surveillance center: abnormal conditions appearred in battery when A and B were high level simultaneously! May be: input voltage be lower than the power supply low-voltage and latchs threshold value, or input voltage is lower than battery link BAT voltage, or battery temperature occurs unusual; Simultaneously, the D1 among Fig. 2 on the node goes out, and D2 goes out.When A is a low level, when B is high level, the PC screen display of Surveillance center: charge; D1 is bright simultaneously, and D2 goes out.When A is a high level, when B was low level, the PC screen display of Surveillance center: charging was finished; D1 goes out simultaneously, and D2 is bright.When A, B were pulse signal, the PC screen display of Surveillance center: battery did not connect; D1 flicker simultaneously, D2 is bright.
The Enable Pin of described display screen connects the output pin of switch control button and MC13224 chip.Switch control to display screen is controlled its Enable Pin by this switch control button, and when button was opened, Enable Pin was opened, display screen initialization of register, operate as normal; Can instruct the height that the Enable Pin level is set to the MC13224 chip by long-range transmission in addition, reach the function same with button.Be that this node can be by opening and closing long-range or node button control display screen, not only conveniently observe image data and battery operated situation at any time but also can save the energy to greatest extent and reduce power consumption.
