Description

Automobile sensing and detection equipment wake-up system

The present invention is a wake-up system for automobile sensing and detection equipment, specifically referring to a technology applied in the automobile field, which mainly lies in being able to effectively control and start the sensing equipment in the automobile, and put it into sleep mode when not in use to reduce power consumption, such as tire pressure detectors and key sensors.

Cars are the most common means of transportation today. With the advancement of technology, the internal mechanisms of cars have also changed from mechanical transmission to electronic. For example, hand-cranked windows have become electronically controlled, and central control electronic screens, tire pressure monitors, IKEY keys, etc. have been added. More and more electronic devices are used in cars.

Although electronic equipment is more in line with people's operating habits and needs than traditional mechanical parts, electronic equipment still requires electricity to operate, and the cost is higher than that of mechanical equipment. Moreover, electronic equipment will not stop operating unless the main power of the car is turned off. Otherwise, as long as the car is in operation, the electronic equipment will be powered and in operation, regardless of whether the car is moving or not, or the electronic equipment is not needed at the moment. In the long run, not only will too much electricity be wasted, but the service life of the electronic equipment will also be quickly consumed, causing users to frequently need to enter the site for repair, maintenance, or even replacement of electronic equipment, thereby generating more unnecessary expenses.

In addition, some electronic devices operate by receiving commands from the car's center console, such as transmitting commands via wavelengths. However, there are many high-tech products in the external environment that emit wavelengths, and it is inevitable that some of the wavelengths are the same or overlap with the command wavelengths issued by the car's center console, causing electronic devices to operate independently under commands not issued by the car's center console, which will also cause power consumption and shorten the service life.

It can be seen that in order to cope with the current technological progress and to slow down the speed of electronic equipment replacement, relevant industries need to consider making improvements in related directions.

The main technology of the present invention is to provide relevant sensing and detection equipment on the car, which can enter a dormant state when not in use, thereby reducing the consumption of power supply and maintaining the service life of the sensing and detection equipment; it improves the defects described in the prior art. When the relevant sensing and detection equipment needs to operate for a long time, not only does it require continuous power supply and cause unnecessary power consumption, but the long-term power supply will also accelerate the service life of the sensing and detection equipment.

However, in order to achieve the above-mentioned purpose and effect, the present invention provides a wake-up system for automobile sensing and detection equipment, which includes: a signal receiving unit, which receives the signal sent by the display module or the outside world; a processing unit, which receives the signal from the signal receiving unit, and the processing unit includes a main control module, a receiving module, a recording module, a data comparison module and a conversion module, and the receiving module, the recording module, the data comparison module and the conversion module The group is electrically connected to the main control module; when the transceiver module has not received the signal sent by the signal receiving unit, the power in the car can only supply a small amount of power to the main control module of the processing unit for operation, and the processing unit is in a deep sleep mode; after the transceiver module receives the signal received by the signal receiving unit, the power in the car supplies a medium amount of power to the main control module of the processing unit for operation, and at this time the transceiver module transmits a signal to the conversion module The conversion module converts the signal into analog/digital and forms a to-be-compared band, and the to-be-compared band enters the data comparison module and is compared with a floating signal comparison band set in the data comparison module, and the comparison result is transmitted to the recording module for recording. At this time, the processing unit is in a dormant operation mode; when the to-be-compared band falls within the band range of the floating signal comparison band, the electric power of the car can supply a large amount of electricity. The power is given to the main control module of the processing unit to operate. At this time, the processing unit is in an awakening operation mode, and the data comparison module returns the matching band to be compared to the conversion module for digital/analog conversion. After the conversion is completed, it is transmitted to the main control module, and the main control module instructs the transceiver module to transmit the converted signal to the multiple sensing devices and multiple detection devices in the car, thereby controlling the multiple sensing devices and multiple detection devices to operate.

According to the above-mentioned description and definition of the present invention, its advantage lies in that, through the settings in the processing unit, when various sensing devices and detection devices are not needed, they can be suspended to reduce power consumption and shorten the service life. In addition, the present invention can also be built into various sensing devices and detection devices. When it comes to vehicles that do not have a display module, it can mainly directly control the awakening of various sensing devices and detection devices, thereby maintaining the service life of various sensing devices and detection devices, and can also achieve the effect of saving electricity. It can be seen that the present invention can be said to be a very practical and progressive creation, which is very worthy of promotion by the industry and public disclosure to the general public.

In order to clearly illustrate that the invention can achieve the above-mentioned purpose and effect, the features and effects of the invention are described in detail with diagrams. Please refer to the first and second figures, the invention is a kind of car sensing and detection device wake-up system, which is mainly built into a display module 101 at the central control position of the car 100, and the power supply of the car 100 is used to operate the display module 101, or built into each detection device 102 of the car 100 or the sensing device 103 (the aforementioned detection device 102 can be a tire pressure detector, and the sensing device 103 can be a wireless key sensor), which includes: A signal receiving unit 10 receives the signal sent by the display module 101 or the outside world. The signal receiving unit 10 can be an antenna; a processing unit 20 receives the signal of the signal receiving unit 10. The processing unit 20 includes a main control module 201, a receiving module 202, a recording module 203, a data matching module 204 and a conversion module 205. The receiving module 202, the recording module 203, the data matching module 204 and the conversion module 205 are electrically connected. In the main control module 201, the transceiver module 202 mainly receives the signal from the signal receiving unit 10 and sends the processed signal to each detection device 102 or the sensing device 103; the recording module 203 records each received signal and the comparison result between each signal and the data comparison module 204; the data comparison module 204 provides the transceiver module 202 with a comparison basis after receiving the signal; the conversion module 205 converts the signal between analog and digital.

According to the above description, the present invention can be divided into three situations for explanation. The first situation is: when the transceiver module 202 has not received the signal sent by the signal receiving unit 10, the main control module 201 of the processing unit 20 can only receive a small amount of power from the car 100 to maintain basic operation. At this time, the processing unit 20 is in a deep sleep mode A.

The second type: When the transceiver module 202 receives the signal received by the signal receiving unit 10, the main control module 201 of the processing unit 20 can receive the power of the car 100 to operate, but it is not enough to completely control the sensing devices 103 and the detection devices 102. It is just to maintain the processing unit 20 to be able to perform calculations. At this time, the transceiver module 202 transmits a signal to the converter. The conversion module 205 performs analog/digital conversion on the signal and forms a to-be-compared band E. The to-be-compared band E enters the data comparison module 204 and is compared with a floating signal comparison band F set in the data comparison module 204. The compared result is transmitted to the recording module 203 for recording. At this time, the processing unit 20 is in a dormant operation mode B.

The third type: when the to-be-compared band E falls within the band range of the floating signal comparison band F, the main control module 201 of the processing unit 20 can receive a large amount of power from the car 100 to operate. At this time, the processing unit 20 is in a wake-up operation mode C. At this time, the processing unit 20 can control each sensing device 103 and each detection device 102, and the data comparison module 204 will match The to-be-compared band E is fed back to the conversion module 205 for digital/analog conversion, and after the conversion is completed, it is transmitted to the main control module 201. The main control module 201 instructs the transceiver module 202 to transmit the converted signal to the multiple sensing devices 103 and the multiple detection devices 102 in the car 100, thereby controlling the multiple sensing devices 103 and the multiple detection devices 102 to operate.

In the signal transmission between the signal receiving unit 10 and the receiving and transmitting module 202 in the processing unit 20, the present invention transmits at a frequency of 60 to 100 per second, so that a plurality of bands E to be compared are formed, and the recording module 203 can record all the bands E to be compared, and the result formed after each band E to be compared is compared with the floating signal reference band F will generate a reference range G. In short, the reference range G refers to the instructions issued by each sensing device 103, the detection device 102, or the display module 101. The instructions issued by the above three devices and modules The wavelengths sent out and received will be received with reference to the reference range G. As long as the wavelength is within the reference range G, the sensing devices 103, the detection devices 102, the display module 101, etc. can start to operate. The wavelengths outside the reference range G cannot start the operations of the above three devices and modules. Although the floating signal reference band F is the initial setting, it will eventually be adjusted and changed according to the reference range G, mainly to dodge and avoid too many wavelengths that are the same as the wavelengths used by the present invention to start the operations of the sensing devices 103, the detection devices 102, the modules, etc., so as to prevent the above devices and modules from starting up automatically.

In addition, the present invention uses the setting of the data comparison module 204 to adjust the upper and lower limits of the range of the floating signal () comparison band (), and its main basis source can be based on the trigger time interval, wavelength energy threshold limit, trigger signal quantity, etc. to filter out interference from other noise and error signals, so that the signal receiving unit can receive the signal that is consistent with and matches the signal wavelength of the central console in the car 100, or consistent with and matches the wavelength range that each sensing device 103 and detection device 102 can receive, thereby preventing the possibility of each sensing device 103, detection device 102, and display module 101 starting up automatically.
