Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Please refer to Fig. 1 and Fig. 2, a kind of training keeps away the barrier car with automatic running, comprising: chassis [1], ultrasonic distance measuring module [2], infrared distance measuring module [3], circuit unit [4], battery unit [5], Universal pulley [6], motor and reducer casing [7], wheel [8]; Ultrasonic distance measuring module [2] is arranged on fore-stock [21], for detection of the distance of the place ahead barrier; Infrared distance measuring module [3] is arranged on side stand [31], for detection of the distance of the right barrier; Fore-stock [21], side stand [31], circuit unit [4], battery unit [5], Universal pulley [6], motor and reducer casing [7] are arranged on chassis [1]; Wheel [8] is arranged on the output shaft of motor and reducer casing [7].
Wherein battery unit [5] comprises switch, battery case and battery; Battery is used for to ultrasonic distance measuring module [2], infrared distance measuring module [3], circuit unit [4] and motor power supply.Ultrasonic distance measuring module [2] and infrared distance measuring module [3] are all analog output modules.Motor and reducer casing [7] comprise right motor and reducer casing [71], left motor and reducer casing [72], and wheel [8] comprises right wheel [81], left wheel [82].
Please refer to Fig. 3, circuit unit [4] comprises single machine unit [41], electric-motor drive unit [42], hummer [43], wireless communication module [44]; Single machine unit [41] consists of electrical connection with ultrasonic distance measuring module [2], infrared distance measuring module [3], electric-motor drive unit [42], hummer [43], wireless communication module [44].
Principle of work is: battery [51] is used for to ultrasonic distance measuring module [2], infrared distance measuring module [3], circuit unit [4] and motor power supply.Single machine unit [41] is take single-chip microcomputer C8051F310 as core, adc circuit by single-chip microcomputer inside is converted to digital quantity with the analog signals of ultrasonic distance measuring module [2], infrared distance measuring module [3] output, thereby measure the distance between dolly and the place ahead, the right barrier, when the distance of the place ahead or the right barrier during less than setpoint distance, single machine unit [41] is sent alarm signal by hummer [43], control simultaneously the rotating speed of left motor [72] and right motor [71] by electric-motor drive unit [42], to change the traffic direction of car body.Single-chip microcomputer communicates by corresponding wireless communication module in wireless communication module [44] and computing machine, by the computer software of supporting design, both can operational mode and the correlation parameter of dolly be configured, and also can monitor the running status of dolly.
Referring to Fig. 4, in conjunction with program flow diagram, further illustrate as follows:
After the switch connection of battery unit [5], circuit unit [4] gets electric, single-chip microcomputer carries out initialization, comprise internal memory zero clearing, port arrangement, ADC configuration, timer configuration, interrupt arranging etc., detection cell voltage after initialization is completed, if voltage is undesired, outputting alarm signal, hummer yowls, and dolly keeps halted state; If voltage is normal, detect the order of whether receiving computing machine, if receive orders processing command, finish dealing with after computer command, detect the distance of the place ahead barrier by ultrasonic distance measuring module [2], detect the distance of the right barrier by infrared distance measuring module [3], if there is barrier in the place ahead, export interrupted alarm signal, and whether the distance that further detects dolly and the place ahead barrier is too near, if distance is not too near (namely not less than the critical distance of setting), dolly advances to the left front, in order to avoid the obstacle in the place ahead; If the distance of the place ahead barrier is too near, less than the critical distance of setting, stopped 3 seconds, then single-chip microcomputer is exported the signal that falls back, and controls left motor [72] and right motor [71] counter-rotating by electric-motor drive unit [42], and dolly retreats, until the distance of dolly and the place ahead barrier meets or exceeds the safe distance of setting, hummer stops alarm, stops 1 second, then continues to detect correlation distance.
When the distance of dolly the place ahead barrier greater than the safe distance set the time, single-chip microcomputer provides the signal of moving of car according to the distance of the right barrier that detects, control the rotating speed of left motor [72] and right motor [71] by electric-motor drive unit [42], allow dolly forwards or the motion of left front, right front.
When the distance that the right barrier detected during less than the space on right set, single-chip microcomputer provides the dolly left rotaring signal, control the rotating speed of left motor [72] and right motor [71] by electric-motor drive unit [42], allow dolly move to the left front, increase the distance of dolly and the right barrier.
When the distance that the right barrier detected during greater than the space on right set, single-chip microcomputer provides the dolly right turn signal, control the rotating speed of left motor [72] and right motor [71] by electric-motor drive unit [42], dolly moves to the right front, reduces the distance of dolly and the right barrier.
If the distance that the right barrier detected is in the space on right interval of setting, single-chip microcomputer provides the dolly progress signal, controls the rotating speed of left motor [72] and right motor [71] by electric-motor drive unit [42], and dolly moves to the dead ahead.
