1) excavator disappears and borrows management
Because excavator monomer is worth comparatively large, in sales process, mainly take mortgage, by stages or the marketing method of financing lease.Due to the credit system that current domestic shortage is perfect, penalty cost is extremely low, client be in arrears with payment for goods even the malice situation of not refunding happen occasionally, cause manufacturer, act on behalf of commercial city and assume responsibility for certain marketing risk.Because manufacturer and commission merchant can not the heavy trucks sold of tracking in time, the safety of equipment is not fully protected, and cheats loan once there is malice, causes huge property loss by giving manufacturer and commission merchant.
2) use safety management
Overall monitor excavator running status, from driver operation to management and monitoring, from real-time reminding to follow-up analysis and summary, at utmost remove a hidden danger, ensure excavator security of operation, gather the various work information of excavator simultaneously, for the development of excavator and upgrading provide detailed Data support.
3) fault Added Management
Use intelligent sensor and vehicle bus technology, realize real-time monitoring alarm, remote fault diagnosis, so that timely queueing problem, ensure that operation is smooth and easy.By gathering the duty of each assembly of onboard sensor, engine information and vehicle, the diagnostic data coordinated in CAN, realize remote fault analysis, Precise Diagnosis.Monitored the ruuning situation of all kinds of mobile unit by bus data, find fault and alarm, stop band " disease " driving.
Accompanying drawing explanation
The block diagram of a kind of gps satellite positioning control system for engineering machinery vehicle that Fig. 1 provides for the utility model;
Fig. 2 is that in the utility model, gps system logs in and power management module schematic diagram.
Embodiment
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1, present embodiment discloses a kind of gps satellite positioning control system for hydraulic excavator, comprise main control unit, main control unit carry, in the original CAN of hydraulic excavator, is also mounted with the original ECU of hydraulic excavator and controller on the bus.Main control unit also logs in gps system with wireless communication module, GPS locating module, real-time clock respectively and power management module is connected, wherein:
Wireless communication module adopts GSM/WCDMA module; GPS locating module adopts GPS/BD locating module.
Composition graphs 2, gps system logs in and power management module comprises main power supply unit, stand-by power supply unit and voltage conversion unit, main power supply unit adopts 24V accumulator, and 24V accumulator is connected with Schmidt's comparer 2 on the one hand, is connected on the other hand via switch 1 with stand-by power supply unit.Stand-by power supply unit adopts 12V stand-by power supply unit, and 12V stand-by power supply unit is connected with Schmidt's comparer 2.The output terminal of Schmidt's comparer 2 is connected with AC-DC power module via switch 23, and AC-DC power module is connected with main control unit, wireless communication module and GPS locating module respectively, by main control unit gauge tap 1 and switch 23.Voltage conversion unit adopts 24V to turn 5V voltage conversion unit, and it is connected with main power supply unit and switch respectively, and switch is connected with main control unit, wireless communication module and GPS locating module.
When systems axiol-ogy is to engine speed, switch 1 closes, and 24V accumulator charges to 12V stand-by power supply unit.When 24V accumulator has electricity, system is by 24V storage battery power supply; And when 24V battery tension drops to 23.5V, system is powered by 12V stand-by power supply unit.When being greater than 24.8V, changing by 24V storage battery power supply, when 12V stand-by power supply cell voltage is greater than 12.5V, by 12V stand-by power supply unit supplying power for outside, when the cell voltage of 12V stand-by power supply unit drops to 12.2V, cutting off reserve battery and powering, system stalls.When switch 23 signal is high level, switch 23 closes to system power supply, and when switch 23 signal is low level, real-time clock produces timing interrupts every the set time (time is adjustable), and gauge tap closes, to system power supply.
When a system is powered up, first (login in) is connected by GPRS and server; Then read effective GPS locating information to send, process the instruction received simultaneously; The timing register write timing of the most backward real-time clock (time that the basis of clock this moment is again fixed), if there is Interruption to produce, eliminates this interruption.
Secondly, when switching signal is high level, GPS module is in running order all the time, reads the RTC current time every one minute simultaneously, then to the time (time is adjustable) of the alarm clock register write timing wake-up of RTC; When switching signal is low level, RTC Interruption produces, and to system power supply, after processing order, eliminate and interrupt, system is in off-position again, waits for timing wake-up next time.
System and server connect and after successful log, want protocol requirement to carry out communication between under GPS communicating terminal and GPS Communications service platform by the communication specified.Communication interface is TCP/IP network interface, supplemental communication mode is SMS(SMS communication), agreement also specify the master data, parameter format etc. of packet, Data Data collection upload the data to GPRS network by GPRS network, then by special line, data are sent to data acquisition center, by data acquisition center data are processed and analyze.After logging in remote service platform, just can inquire about to corresponding machine information the parameter information comprising geographic position and machine itself, working condition, working time, operating efficiency etc., can also carry out gathering by sending command word the real-time information of machine, also can send corresponding classification car locking information, machine is controlled.Can also car locking information inquiry be passed through, check whether the command word of transmission comes into force.
Assemble the hydraulic excavator of this GPS terminal, main engine plants effectively can carry out managing, control, inquire about, and are conducive to safety, sale, service, credits management etc.
The utility model gps satellite positioning control system is except also can be used for other similar engineering motor vehicles and machines except hydraulic excavator.
