Abstract
The utility model discloses a temperature detecting device for a road roller. The temperature detecting device for the road roller comprises a sensor, a switching circuit, an amplifying circuit, an analog to digital (A/D) switching circuit, a single chip microcomputer circuit, a display screen, a buzzer, a keyboard and a storage , wherein the sensor is orderly connected with an input end of the single chip microcomputer circuit after being connected with the switching circuit, the amplifying circuit and the A/D switching circuit in series, the output end of the single chip microcomputer circuit is respectively connected with the display screen and the buzzer, the other input end of the single chip microcomputer circuit is connected with the keyboard, and the single chip microcomputer circuit is connected with the storage. Compared with the prior art, the temperature detecting device for the road roller can conveniently and correspondingly regulates variation frequency and amplitude of a vibroll, walking speed and size of sprinkling water and the like in time according to display temperature of the display and prompting of sound and technical requirement of braking for operators, thereby greatly reducing operation time delay error brought by detection temperature of workers, and improving work efficiency.
Description
Technical field
The utility model relates to a kind of temperature-detecting device, is specifically related to a kind of road roller temperature-detecting device.
Background technology
At present, the control of temperature in the hot-mix asphalt mixture roller compaction construction process is main to rely on the constructor that the temperature that detects is offered operator, and the temperature that operator detects according to the constructor and the pass that rolls determine whether road roller opens the associative operations such as vibration.Although this working method can be made suitable operation opportunity in the temperature that is fit to, but need to increase the special messenger at work progress and carry out detected temperatures, not only improved engineering cost, and the constructor shuttles back and forth in the road roller intermediate detection temperature of operation, dangerous high, also there is certain hysteresis quality in detected temperatures simultaneously.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of road roller temperature-detecting device is provided.
Its technical scheme is: comprise sensor, change-over circuit, amplifying circuit, A/D change-over circuit, single chip circuit, display screen, buzzer, keyboard and memory.An input in single chip circuit behind the change-over circuit of described sensor by connection in sequential series, amplifying circuit, the A/D change-over circuit is connected, the output of single chip circuit is connected with display screen and buzzer respectively, another input of single chip circuit is connected with keyboard, is connected with memory on the single chip circuit.
Wherein, described sensor is infrared temperature sensor, and it is made as 1-6.Described change-over circuit is changeover switch.Described display screen is the LED digital display screen.
The utility model compared with prior art, temperature and sound prompt that the handled easily hand shows according to display screen, according to the technical requirements that rolls in time to frequency, the amplitude of vibratory roller vibration, the speed of walking, the size of spray water etc. is made corresponding adjustment, greatly reduce the operation delay error brought because of the manual detection temperature, improved operating efficiency.In addition, the utility model need not manually to carry out temperature detection, does not have the workman in the road roller intermediate detection temperature of shuttling back and forth, and is safe.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, a kind of road roller temperature-detecting device comprises sensor 1, change-over circuit 2, amplifying circuit 3, A/D change-over circuit 4, single chip circuit 5, display screen 6, buzzer 7, keyboard 8 and memory 9.Described sensor 1 is connected with an input of single chip circuit 5 afterwards by change-over circuit 2, amplifying circuit 3, the A/D change-over circuit 4 of connection in sequential series, the output of single chip circuit 5 is connected with display screen 6 and buzzer 7 respectively, another input of single chip circuit 5 is connected with keyboard 8, is connected with memory 9 on the single chip circuit 5.Wherein, described sensor 1 is infrared temperature sensor, and it is made as 1-6, is 2 among the figure, these sensors 1 can distributing installation at road roller all around on the desired position, its temperature sense point drops on the bituminous mixture that will roll.Described change-over circuit 2 is changeover switch.Described display screen 6 is the LED digital display screen.
