Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, piezoelectric sensor 1, signal generator 2, identity code receiver 3, ultrasonic transmitter 4, ultrasonic receiver 5, temperature, pressure recognizer 6, ultrasonic temperature converter 7, data coding module 8, bluetooth radio module 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, content of the present invention is described further.
As shown in Figure 1, wireless temperature measurement pressure measurement intelligent object of the present invention comprises: a piezoelectric sensor 1, signal generator 2, identity code receiver 3, ultrasonic transmitter 4, ultrasonic receiver 5, temperature, pressure recognizer 6, ultrasonic temperature converter 7, data coding module 8 and blue teeth wireless transmitter module 9.
Piezoelectric sensor 1 connects ultrasonic transmitter 4 and ultrasonic receiver 5, and signal generator 2 connects ultrasonic transmitter, provides temperature measurement signal to transmitter.Ultrasonic receiver 5 connection identifier code 3, so that the unpaired message receiving that other use the equipment (hereinafter referred to as application apparatus) of wireless temperature and pressure-detecting device; Ultrasonic receiver 5 connects temperature, pressure recognizer simultaneously.Temperature, pressure recognizer 6 determines that ultrasonic receiver 5 temperature and pressure measures pressure, then direct by the signal of reception after data coding module 8 and identification code 3 are packed, send to the bluetooth radio module 9 be connected with oneself, send the data to application apparatus.If it is measuring tempeature that temperature, pressure recognizer 6 picks out.The ultrasonic transmitter 4 just connected by 6 enters transmitting work.Ultrasonic transmitter 4, just by the frequency signal of signal generator 2, sends to piezoelectric sensor 1.
Above-mentioned wireless temperature measurement pressure measurement intelligent object is applied on the pot cover handle of pressure cooker, thus makes it can be arranged on any nonmetal pot lid easily, the intelligent wireless thermometric pressure measurement of composition all size.
Further improvement, and for the body of heater of hot hole, the computer heating control intelligent object of such as electromagnetic oven combines, realize one complete can only culinary art scheme.
The course of work of the intelligent temperature measurement manometric module that the present invention is above-mentioned is as follows: first, by ultrasonic receiver 5, whether the signal detecting piezoelectric sensor 1 exceedes the numerical range of normal heating pressure generation, does pressure detection still do temperature detection so as to recognition device.If it is determined that pressure exceedes normal pressure, according to pressure sensor module work, send data coding module 8 by detection data, after data coding module 8 is designated pressure data, send to application apparatus through bluetooth radio module 9; If constant at regular hour pressure, then pressure and temp detects the driving frequency that recognizer 6 drives ultrasonic transmitter 4 amplifying signal generator 2, drives piezoelectric sensor 1 to launch ultrasound wave to the bottom of a pan.
