Embodiment

The utility model provides a kind of electronic device that is used for detecting states such as operation way doughnut internal gas pressure, temperature.It detects information such as tire internal gas pressure, temperature in real time by the intelligence sensor that is installed in the tire, and these status informations is sent to immediately the monitor controller that is positioned at pilothouse by wireless telecommunications.The monitoring main frame can show and analyze the data that receive, just send alerting signal to the driver in case note abnormalities.The monitoring main frame can also send to remote terminal with vehicle state information by wireless networks such as GSM/CDMA, or handheld terminal, as mobile phone or car key, thereby can make the user grasp vehicle condition conveniently, timely, or realize remote diagnosis and control and treatment.

Described doughnut state detector comprises: is installed in the intelligence sensor 1 on the automotive wheels wheel, is installed in the monitor controller 2 in the pilothouse, be installed in the telecommunication module 3 in the compartment, and handheld terminal 4.Shown in Figure 1 is the system architecture of detector.

The function of intelligence sensor is regularly to detect states such as the pressure in the tire, temperature in the operation way, and detected data are sent to monitor controller with wireless mode.Because intelligence sensor is mounted on the wheel wheel, therefore adopt powered battery usually.Intelligence sensor 1 is a core with first microprocessor 11, second radio-frequency (RF) transceiver 12, state detector 13, comprises battery 14 and peripheral auxiliary circuits 15 in addition.Fig. 2 is the basic structure of intelligence sensor 1.

In order to prolong the working time of intelligence sensor, must adopt little power consumption design to reduce the power consumption of intelligence sensor.Little power consumption design that the utility model adopts comprises hardware design and software design.Little power consumption design at hardware aspect comprises again: (1) adopts VLSI (very large scale integrated circuit) chip, reduce peripheral components quantity, improve level of integrated system, the first microprocessor 11 that the intelligence sensor of the utility model design adopts is the PIC16F684 single-chip microcomputer, only need energized to get final product work by any peripheral cell, it is the simplest microprocessing systems, first radio-frequency (RF) transceiver 12 adopts monolithic integrated wireless transceiving chip nRF2401A, than other wireless telecommunications chips, ten of its peripheral cell less thaies, and has the duplex signaling function, communication frequency is 2.4GHz, can effectively avoid intercom, the interference of common communication apparatus such as mobile phone, thereby communication is reliable, state detector 13 comprises acceleration transducer, pressure transducer and temperature sensor adopt 4 to close 1 monolithic SP12.(2) preferred little power consumption type device, the running current of the first microprocessor P1C16F684 that the utility model is selected for use is about 8.5uA, the current drain of standby sleep state only is 1nA:(3) increase acceleration transducer to realize that vehicle moves measuring ability, make only work when vehicle moves of state detector, other the time be in the sleep pattern of little power consumption automatically.Little power consumption design aspect software comprises: (1) adopts variable period regularly to detect strategy, timing cycle is adjusted automatically according to force value, pressure is divided into place of safety, sensitizing range and explosive area, in place of safety timing cycle maximum, and along with pressure progresses into the sensitizing range or shorten gradually in the explosive area: (2) sleeping function automatically, judge based on acceleration transducer whether vehicle stops, if confirm that vehicle stops then to enter automatically sleep state, the intelligence sensor module is least in power-consuming at this moment; (3) Auto Power On function, whether detect vehicle based on acceleration transducer mobile, if confirm that vehicle moves then Auto Power On, and according to the state in the variable period timing strategy detection tire.

During variable period regularly detected, the cycle to the adaptive control of force value as shown in Figure 4.Wherein, in each sense cycle, adaptive algorithm is made comparisons detected current atmospheric pressure value and current temperature value respectively with default standard pressure value and standard temperature value, obtain current air pressure deviation amount and Current Temperatures deviation.If current air pressure deviation amount greater than historical air pressure deviation amount, then reduces the sense cycle value 1 unit; If current air pressure deviation amount less than historical air pressure deviation amount, then increases 1 unit with the sense cycle value; If the Current Temperatures departure greater than historical temperature deviation amount, then reduces the sense cycle value 1 unit; If the Current Temperatures departure less than historical temperature deviation amount, then increases 1 unit with the sense cycle value.At last, upgrade historical air pressure deviation value and historical temperature deviation value respectively with current air pressure deviation value and Current Temperatures deviate.

Be integrated with acceleration transducer in the intelligence sensor 1, when wheel brief acceleration sensor to normal acceleration can change, can judge that thus whether vehicle moves, and then the sleeping function automatically and the Auto Power On function of design intelligence sensor.
