Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the present invention includes temperature sensor, camera head, wireless communication device, data processor, described camera head is connected with the input end of described data processor respectively with the output terminal of described temperature sensor, the output terminal of described data processor is connected with the input end of described wireless communication device, and described wireless communication device is connected with alert detecting terminal wireless.
As shown in Figure 1, described data processor comprises wave filter, amplifier, A/D converter, digital signal processor, the input end of described wave filter is connected with described temperature sensor output terminal, the output terminal of described wave filter is connected with the input end of described amplifier, the output terminal of described amplifier is connected with the input end of described A/D converter, the output terminal of described A/D converter is connected with the input end of described digital signal processor, and the output terminal of described digital signal processor is connected with the input end of described wireless communication device.
The object of digital signal processor measures or filtering the continuous analog signal of view data and ambient temperature data feedback.Therefore before carrying out digital signal processing, need oily signal from analog territory to be transformed into numeric field, this is realized by analog to digital converter (A/D) usually.And the output of digital signal processing often also will transform to analog domain, this is realized by digital to analog converter.The algorithm of digital signal processing needs to utilize computing machine or dedicated treatment facility as digital signal processor (DSP), the core algorithm of digital signal processing is discrete Fourier transformation (DFT), be that DFT makes signal achieve discretize at numeric field and frequency domain, thus general-purpose computer processes discrete signal can be used.And make digital signal processing move towards practical from theory to be Fast Fourier Transform (FFT) (FFT), to decrease the operand of DFT, digital signal is processed in real time.
Described wireless communication device is WIFI wireless communication device, GPRS wireless communication device or blue tooth wireless communication device, and support multiple transport protocols, described temperature sensor is connected by CAN with described data processor respectively with described camera head.CAN connects, and CAN belongs to the category of fieldbus, the serial communications network that it is a kind of effective support distributed AC servo system or controls in real time.Than the distributed control means that many RS-485 build based on R line, distributed control means based on CAN has obvious superiority in the following areas: the data communication between each node of network is real-time, first, CAN controller works in various ways, each node in network all can adopt the mode of the bit-by-bit arbitration of harmless structure to compete according to bus access right of priority (depending on message identifier) and send data to bus, and CAN protocol has abolished station address coding, and replace communication data is encoded, this can make different nodes receive identical data simultaneously, data communication between each node of the network that these features make CAN form is real-time, and easily form redundancy structure, improve the reliability of device and the dirigibility of device.Shorten the construction cycle, CAN is connected with physical bus by two output terminal CANH with CANL of CAN transceiver interface chip 82C250, and the state of CANH end can only be high level or suspended state, and CANL end can only be low level or suspended state.This just ensures to appear at the phenomenon in RS-485 network, namely when device is wrong, when occurring that multinode sends data to bus simultaneously, causes bus to present short circuit, thus damages the phenomenon of some node.And CAN node has when mistake is serious and automatically closes output function, to make the operation of other nodes in bus unaffected, thus ensure there will not be to resemble in a network, because respective nodes goes wrong, make bus be in " deadlock " state.
The present invention by temperature sensor and camera head view data and ambient temperature data is fed back through CAN or wireless mode is transferred to data processor, data processor is by carrying out filtering, amplification, A/D conversion, computing etc. to signal, finally draw correct characteristic parameter value and be transferred to alert detecting terminal demonstration, be reached through the data knots modification of monitoring household in real time and judge whether there is situation in household.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included in protection scope of the present invention.
