Specific embodiment

Below in conjunction with attached drawing, the utility model is further described by specific embodiment.

As shown in Figure 1, a kind of interior range-measurement system, including controller 1, distance measuring sensor 2, key module 3, power module 4, Liquid Crystal Module 5 and buzzer module 6；Distance measuring sensor 2 is electrically connected with the input terminal of controller 1, Liquid Crystal Module 5 and buzzing Device module 6 is electrically connected with the output end of controller 1 respectively, and controller 1 passes through Liquid Crystal Module 5 for distance measuring signal is received after processing Display distance simultaneously carries out warning note by buzzer module 6；Key module 3 is electrically connected with the input terminal of controller 1, to right The adjustment of 6 volume of buzzer module；Power module 4 is connected by switch with controller 1, to supply entire range-measurement system Electricity.

As shown in Fig. 2, controller 1 be by crystal oscillating circuit, reset circuit and singlechip group at single-chip microcontroller minimum control system System.Single-chip microcontroller uses STC89C52 cake core.Crystal-oscillator circuit includes two 30 pf capacitors C2 and C3.Reset circuit is When system in operation, receive the influence of external influence or self stability, cause system data operation there is mistake When, only it need to press reset button, system will be from re-executing order.Since the P0 mouth of STC89C52 is open-drain output, So upper in conventional P0 mouth and added the exclusion R1 of a 10K, and the purpose that R1 group is arranged be make P0 mouthfuls can be used as it is general Logical normal I/O mouth that everybody is accustomed to uses, and herein, P0 mouthfuls be for 1602 liquid crystal as data transmission mouth, I.e. 1602 data are exactly to pass through conducting wire data line to be connected on P0 mouth, and then single-chip microcontroller is counted in ultrasonic wave detecting system According to rear, 1602 are transferred data to through processor of single chip computer, finally, data are converted digital information by 1602 liquid crystal, is shown in On liquid crystal display, convenient for users to intuitively obtaining metrical information result.
