Abstract

A distance measuring system based on a mobile phone is characterized by comprising the mobile phone and a distance measuring peripheral, wherein the distance measuring peripheral transmits data with the mobile phone through a USB interface and obtains supplied power from the mobile phone through the USB interface. The distance measuring peripheral internally comprises the USB interface, a USB interface controller, a processor and a distance measuring module. According to the distance measuring system, the distance measuring peripheral is used for measuring distances between objects, and the mobile phone is used for displaying and processing measurement data in later period. The distance measuring peripheral serves as a peripheral of the mobile phone, is connected with the mobile phone to be used in the distance measuring process, and has the advantages of being small in size and easy to carry and operate. Powerful data processing capacity and a screen rich in display content of the mobile phone are used, and therefore the distance measuring system further can achieve area and size calculation.

Description

A kind of ranging system based on mobile phone

Technical field

The present invention relates to a kind of ranging system, especially a kind of Portable measuring system, is characterized in utilizing the mobile phone peripheral hardware of a small size to measure the distance between object, utilizes mobile phone or panel computer to carry out demonstration and the processing of data.

Background technology

In daily life, often need to carry out distance and measurement of length, in the ordinary course of things, be all to use tape measure or tape measuring.The volume of tape measure is little, but range is also little, and tape measure range is large, but volume is large.When measuring, also need tester to walk up and down, use inconvenience.Also there are on the market ultrasonic range finder and infrared range-measurement system can carry out easily range measurement, but on the high side.Therefore and people can not carry these range finding article, cannot accomplish to find range whenever and wherever possible.

Smart mobile phone has powerful data-handling capacity and the abundant screen of displaying contents.But at present the application of smart mobile phone mainly comprises and making a phone call, and sends short messages, online, sees a film, the function such as play games.Its powerful disposal ability also has very large application potential to excavate.By coordinating various mobile phone ancillary equipment, smart mobile phone can for people bring more convenient.

In order to expand the function of smart mobile phone, Chinese patent < < smart mobile phone external device > > (number of patent application: 201210066870.X) announced a kind of mobile phone peripheral hardware, it is comprised of handset shell and function module card two parts, wherein, on handset shell with USB plug and audio jack; Function module card is built-in with functional chip, its periphery or side are distributed with metal needle or hard contact, it is characterized in that: also preset USB hub, data wire and data interface unit in the plastic substrate of described handset shell, the data wire of USB plug is connected on USB hub, the other end of USB hub can separate multi-group data line cap and be connected on the lip-deep a plurality of data interface units of mobile phone shell, forms thus the handset shell with communication repeating function; On described function module card, be provided with especially data-interface, it can make to fix with mobile phone shell in function module card data inserting interface equipment, and forms electrical connection.In this patent, by the usb hub of phone housing form, realize and expanded many dissimilar functional module peripheral hardwares.The module of these Various Functions is to be all multi-formly connected to mobile phone shell usb hub with various, and then is connected to the USB interface of mobile phone.Be characterized in powerful and peripheral hardware abundant species.Its shortcoming is: (1) has increased usb hub between functional module and mobile phone, causes the increase of cost; (2) some module has been used the self-defining interface of this patent, belongs to off-gauge interface, causes the heterogeneity on using; (3) overgenerous function causes the complexity of system to increase, the increase of the increase of mobile phone volume and power consumption.

In some other patent, also have and to find range in conjunction with mobile phone, as Chinese patent < < distance measurement mobile phone > > (number of patent application: 200920280143.7), Chinese patent < < Mobile phone for laser distance measurement > > (patent No.: 201020639150.4).The range finding implementation method of these patents is all integrated into interior of mobile phone range-measuring circuit and realizes, and its shortcoming is to carry out specially the design of mobile phone, thereby has increased complexity and the cost of mobile phone.

The present invention is put into distance measurement function in mobile phone peripheral hardware and realizes, and by USB interface, test data is sent to mobile phone shows and post-processed.USB has hot plug, and interface is simple and easy to the feature of use.As long as there is the mobile phone of USB OTG function, can use this peripheral hardware.Peripheral hardware, by suitable design, can also or be embedded into mobile phone protecting case the inside as Mobile phone pendant ornament and go, easy to carry, easily changes and dismantles.Utilize the powerful calculating ability of mobile phone and friendly display screen, easily realize range measurement, area measurement and cubing.

Summary of the invention

The object of the present invention is to provide a kind of volume little, price is low, Range Measurement System easy to carry.Mainly comprise mobile phone terminal software and range finding peripheral hardware; Mobile phone is connected by USB interface with range finding peripheral hardware.Range finding peripheral hardware is as the pendant ornament of mobile phone or phone housing or mobile phone protective cover or annex and independent existence closely connects mobile phone by USB interface when measuring.Mobile phone is belongings, and distance measurement function is integrated on peripheral hardware, and as the adjunct of mobile phone, also becoming is belongings.Just easily realize thus range measurement anywhere or anytime.
