Abstract
The invention discloses a silicone oil fan tester which comprises a power supply module, a main control CPU (central processing unit) module, a display module, a scanning module and an input/output module, wherein the main control CPU module adopts C8051FC310; and the input/output module adopts CH375. The silicone oil fan tester used for detecting and judging the invalidation condition of an electrically-controlled silicone oil fan on a finished vehicle can be used for rapidly judging the application mode of the electrically-controlled silicone oil fan on the finished vehicle; and the silicone oil fan tester can be connected with the electrically-controlled silicone oil fan through a detection box with a self power supply and can be used for simulating the process that an ECU (electronic control unit) of the finished vehicle outputs signals to the electrically-controlled silicone oil fan, detecting the revolving speed and resistance of the fan and displaying the values of the revolving speed and resistance of the fan.
Description
Technical field
The present invention relates to automotive electronic control system silicon-oil fan field, specifically is the silicon-oil fan tester, in order to detect and to judge the failure conditions of automatically controlled silicon-oil fan on car load.
Background technology
Automatically controlled silicon-oil fan is the high efficiency energy-conserving radiator fan for high-end commercial car design.It can regulate rotating speed, to satisfy the different radiating requirements of engine automatically according to engine coolant temperature under the signal controlling of ECU.
The use of automatically controlled silicon-oil fan on car load is in order to save fuel consume; Reduce toxic emission; This is technical at cooling fan of engine to be a developing direction and development trend, has had increasing car load factory and engine works to begin to pay close attention to and use this technology.
Because automatically controlled silicon-oil fan is just promoted the use of at home, technology is not the branch maturation, so in the process of using, the phenomenon of the erroneous judgement of usually breaking down.Qualified and the underproof product of the identification that car load often can't be prepared has influenced vehicle performance.
Moreover can not have relevant technical information and product in the disclosed information in the art both at home and abroad yet, bring many puzzlements for the production and the judgement of product.
Summary of the invention
The present invention seeks on car load, directly automatically controlled silicon-oil fan to be detected judgement, guarantee the correct use of automatically controlled silicon-oil fan on car load, the special silicon-oil fan tester that proposes.
Technical scheme of the present invention for this reason is that the silicon-oil fan tester comprises power module, it is characterized in that:
Comprise the master cpu module, display module, scan module, input/output module.
Improvement to such scheme is: described master cpu module is to adopt C8051FC310.
Improvement again to such scheme is: that input/output module adopts is CH375.
Beneficial effect:
The present invention designs basically and is to use a self-powered detection box, can be connected with automatically controlled silicon-oil fan, and simulation car load ECU detects the rotating speed and the resistance of fan, and shows its value to automatically controlled silicon-oil fan output signal.The use of silicon-oil fan tester has been filled up both at home and abroad about the technological gap of silicon-oil fan, can detect rapidly when reporting to the police appears in car load whether this source of reporting to the police is automatically controlled silicon-oil fan, for the investigation of fault provides method efficiently and effectively.It is portable, lightly also brought convenience for detecting.

Embodiment
Like Fig. 1,2,3,4, shown in 5, detector is made up of power module, master cpu, display module, scan module and 5 parts of input/output module.Lithium battery and inversion module are the voltage of detector requirement with power source conversion and are its power supply in the power module; Master cpu is the core of detector, and it generates pwm signal according to demand, through output interface signal is exported to automatically controlled silicon-oil fan, and accepts the tach signal of fan feedback through input interface; Display module can be shown in the form of above signal with numerical value on the screen, is convenient to read.Wherein the master cpu module is to adopt C8051FC310, and that input/output module adopts is CH375.
Claims (3)
1. the silicon-oil fan tester comprises power module, it is characterized in that:
Comprise the master cpu module, display module, scan module, input/output module.
2. silicon-oil fan tester according to claim 1 is characterized in that: the master cpu module is to adopt C8051FC310.
3. silicon-oil fan tester according to claim 1 is characterized in that: that input/output module adopts is CH375.
