Abstract
The utility model discloses a monitor for a bulldozer. A pointer instrument, a liquid crystal display, alarm lamps and a setting button are mounted on a casing panel; and a controller is mounted in the casing. The pointer instrument is an electronic type stepped motor instrument. The controller comprises a CPU, an FLASH memory, a CAN chip, a real-time clock chip, a memory, a display control chip and an LED lamp drive chip. The point instrument is arranged at the upper part of the casing panel; the liquid crystal display is arranged in the middle of the casing panel; the alarm lamps are positioned on two sides of the liquid crystal display; and the setting button is positioned at the lower part of the liquid crystal display. The pointer instrument is used for displaying the water temperature of the motor, the temperature of hydraulic oil of a traveling system, the motor oil pressure of the motor and the work voltage of the system; the liquid crystal display is mainly used for displaying the operation state and the operation parameters of the bulldozer, fault information of an electrical system of the finished vehicle, fault information of the motor and the like; and the alarm lamps are used for displaying the alarm of the fault information. The utility model has the advantages of high integrated degree and powerful function of displaying the alarm, and can be widely used for the bulldozer and other engineering machines.
Description
Technical field:
The utility model relates to a kind of bulldozer watch-dog, the instrument of when being the work of a kind of bulldozer the complete machine operational factor being monitored.
Background technology:
Original bulldozer watch-dog generally is made of induction type pointer Displaying Meter and alarm lamp, and the information of supervision is not comprehensive, and induction type pointer demonstration reliability and accuracy are relatively poor.
Summary of the invention:
The purpose of this utility model provides a kind of bulldozer watch-dog, solve original monitor information not comprehensively, reliability and the relatively poor defective of accuracy.
The purpose of this utility model realizes as follows: a housing is arranged, pointer instrument, LCD, alarm lamp and setting button are housed on the case panel, controller is housed in the housing.
The pointer instrument is an electronic type stepper motor instrument.
Controller drives chip by CPU, FLASH flash memory, CAN chip, real-time timepiece chip, memory, display control chip and LED lamp and forms.
The pointer instrument is arranged on case panel top, and LCD is arranged at the middle part, and alarm lamp is in the LCD both sides, sets button and is in the LCD bottom.
The operation of ARM kernel CPU control whole system, watch-dog is used the CAN bus with outside communicating by letter.CAN bus external node has equipment such as Engine ECU, fault detect ECU, walking control ECU, display receives corresponding information on the CAN bus, shows engine coolant temperature, engine oil pressure, amount of fuel, walking pressure, bulldozer operational factor go forward side by side line parameter and operation troubles warning.
Watch-dog can show engine information and engine failure information, as engine speed, motor operation total time etc., the operational factor that can show complete machine, as the speed of a motor vehicle, hydraulic system parameters etc., can show the complete machine fault alarm information, can also carry out user's setting, carry out password setting, the car load electric controller is carried out the parameter setting, as revising temperature-controlled fan parameter etc.
The utility model adopts advanced micro-step motor to drive the pointer instrument, compares with induction type pointer commonly used, and reliability is higher, and versatility is stronger.Micro-step motor is selected senior ferromagnetic material and special, wear-resistant plastics for use, takes into account security performances such as fire prevention simultaneously, adopts the special tooth profile with noise elimination and wear-resisting effect, has guaranteed the long-term operation life-span and the performance of motor.Except the trend that pointer is provided shows, also carry out the demonstration of literal, picture in conjunction with the giant-screen lattice lcd, display mode is abundant more and directly perceived.The automatic checkout system fault, prompting and record trouble are convenient to reviewing of user's maintenance and security of system.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
The specific embodiment:
With reference to Fig. 1, a housing 1 is arranged, pointer instrument 3, LCD 4, alarm lamp 2 are housed on housing 1 panel and set button 5, in the housing 1 controller is housed.Pointer instrument 3 is arranged on housing 1 panel top, and LCD 4 is arranged at the middle part, and alarm lamp 2 is in LCD 4 both sides, sets button 5 and is in LCD 4 bottoms.Pointer instrument 3 is an electronic type stepper motor instrument, and pointer instrument 3 is used for showing engine water temperature, running gear hydraulic fluid temperature, engine motor oil pressure and system works voltage; LCD 4 is mainly used to show the running status and the operational factor of bulldozer, and the fault message of car load electrical system and engine failure information etc.; Alarm lamp 2 is used for showing the warning of fault message.
With reference to Fig. 2, memory, display control chip and LED lamp that controller is used by CAN chip, the real-time timepiece chip that is used for producing real-time clock, the stored parameter of ARM series CPU, FLASH flash memory, communication usefulness drive chip and form.Specifically, there are power supply, memory, FLASH, keyboard drive, liquid crystal drive, stepper motor driving, LED driving, CAN chip, CAN bus to be connected with CPU, the CAN bus is outside to be connected with miscellaneous equipment, liquid crystal drive is connected with liquid crystal display, stepper motor drives and is connected with stepper motor, and liquid crystal drive is connected with the LED malfunction indicator lamp.Liquid crystal display is the LCD 4 among Fig. 1; The LED malfunction indicator lamp is the alarm lamp 2 among Fig. 1.
