Abstract
The utility model brings forward a power measuring device for a diesel oil engine. The power measuring device for a diesel oil engine comprises an upper computer measuring device, a diesel oil engine power measuring system, an engine control system, a communication connecting device, and a signal conversion device, wherein the upper computer power measuring device is connected with the diesel oil engine power measuring system through the communication connecting device, and the engine control system is connected with a signal connection device through a signal conversion device. Digital signals output by an engine are converted into simulation signals needed by the engine control system through the signal conversion device, and therefore control over the diesel oil engine can be realized.
Description
Technical field
The utility model relates to engine measurement of power field, refers to especially a kind of diesel motor power measurement arrangement.
Background technology
Existing diesel motor power signal is all digital quantity, and the analog quantity power signal of the 4-20mA that existing engine control system needs, the signal of this engine output is different, can not realize diesel motor is controlled.
The utility model content
The utility model proposes a kind of diesel motor power measurement arrangement, diesel motor power digital signal is converted to the simulating signal that control system can read, thereby realized the engine measurement of power is controlled.
The technical solution of the utility model is achieved in that a kind of diesel motor power measurement arrangement, comprise host computer device for testing power, diesel motor power-measuring system, engine control system, communication link and chromacoder, described host computer device for testing power and diesel motor power-measuring system interconnect by communication link, and engine control system is connected with signal connection device by chromacoder.
Further, described communication link is the RS232 bus.
Further, described chromacoder is the D/A converting unit.
The host computer device for testing power communicates by serial RS232 and diesel motor power-measuring system, obtains the digital quantity power signal of diesel motor.Simultaneously, communication port output in parallel one road signal from the diesel motor power-measuring system connects the D/A converting unit.The communication data that comprises the relevant informations such as moment of torsion, rotating speed of D/A converting unit intercepting power-measuring system output, transmission mode is hexadecimal string.The D/A converting unit is decomposed the communication character string by programming, extracts moment of torsion and tachometer value, and (P=N*V/9550, P are performance number-KW, and N is torque value-Nm, and V is that tachometer value-R/MIN) calculates performance number according to formula; Then by the D/A converting unit, performance number is exported with the current signal of 4-20mA; At last current signal is inputted engine control system, thereby realize the control to diesel motor.
