Embodiment
are as shown in Figure 1, and the utility model comprises controller, seismoreceiver, storer, execution relay, and its structural feature controller links to each other with seismoreceiver, storer, execution relay respectively.
said seismoreceiver adopts 3-axis acceleration sensor.
the utility model also comprises voice output part, liquid-crystal display section and serial ports external interface, and said controller links to each other with voice output part, liquid-crystal display section, serial ports external interface respectively.
The model of
said 3-axis acceleration sensor is MMA7455L.MMA7455L provides digital interface, and the register that the user can directly read MMA7455L obtains exporting digital quantity, and user friendly data processing can be used on the MCU that does not have the A/D interface as usual.The I2C bus communication can use MCU Hardware I 2C unit, also can use Simulation with I 2C communication, to the support extensive more (Fig. 2 and Fig. 3 represent the seismoreceiver and the mode of connection of the MCU with Hardware I 2C with the MCU that adopts Simulation with I 2C respectively) of MCU.
provide I2C and SPI digital interface, and MMA7455L is the I2C interface as slave unit when the CS of MMA7455L pin is drawn high, and when CS is used as from selection, are the SPI interface.The utility model adopts the I2C interface, and it is 0x1D from the address, supports the multibyte read-write.Pin AVDD is in 2.4～3.6V scope, and representative value is 2.8V.Consider circuit and external interface situation, look the I2C interface level of controller and select the DVDD_IO pin voltage.If adopt the Switching Power Supply power supply, note that switching frequency must be greater than 250 Hz, with anti-tampering MMA7455L chip internal ASIC.
The largest sample rate of
is 250 Hz, and its data rate gets final product greater than 2.5kbps; The I2C pull-up resistor does not have the correlation computations formula in the data of being obtained, can adopt empirical value 4.7kHz, can suitably reduce than length through analog switch or cabling if need.
provide 2 to interrupt output pins, and INT1 is shared with DRDY, and need confirmed the output of INT1 and INT2 in actual the use according to application requirements.
said controller adopts dsp controller; Can adopt the series DSP TMS320DM642 controller of LPC2100 or TI company, TMS320DM642 is applicable to a large amount of digital signal processing computings and takes into account the occasion of high real-time requirement, can satisfy the demonstration of system's real time data computing and graphical interfaces.
said storer adopts the Flash storer, in order to data such as the setting parameter of storing this device and Operation Logs; Can adopt the AM29LV033C storer of 32 Mb of AMD.
the utility model has two rank outputs, is respectively the output of one-level earthquake intensity contact, and the output of secondary earthquake intensity contact inserts electric power system respectively.
(1) early warning system: seismoreceiver detects the output behind the perhaps lower seismic motion acceleration of the early stage p ripple vibration of earthquake; Be more low-level output; Be used for judging earthquake may take place that sending the sound and light alarm prompting has earthquake to take place.If there is not the earthquake of higher level, then automatically reset, contact signal disappears.
