Abstract

The invention discloses a test system for vehicle quiescent current, comprising a vehicle electric power source arranged in a vehicle to be tested; a controlled unit and a standard resistor formed by vehicle electric load and connected with a loop in series; a control unit arranged outside the vehicle to be tested for controlling the opening and closing of the controlled unit; a data acquisition module arranged outside the vehicle to be tested for acquiring voltage of the standard resistor at two terminals; a data conversion module arranged outside the vehicle to be tested for converting the data collected by the data acquisition module to electric current. Therefore, the long time and continuous test for the vehicle voltage can be realized, the voltage of the vehicle tested by the test can accord with requirement; the disadvantage of successful starting with difficulty can be avoided, after long time lying idle of the vehicle; the subsequent quality complaint can be avoided.

Description

Test system for vehicle quiescent current
Technical field
The present invention relates to a kind of current detecting system, particularly a kind of test system for vehicle quiescent current.
Background technology
In recent years, along with the development of automobile industry, the dolly that China has developed all kinds of models satisfies the demand of different crowd.For guaranteeing the quality of dolly, production firm will carry out multiple detection to dolly before automobile dispatches from the factory, and comprising the test to the dolly power supply, prevents to be difficult to support the complaint after sale that long-term placement produces because of the design electric energy deficiency of dolly.And the method for testing that has now the electric current that power supply provided is to use multimeter to test by the tester.Since be hot line job, therefore very high, careless slightly to tester's manual skill requirement, cause the generation of Danger Electric shock risk easily.Have again, just some test of this kind test, be difficult to the supporting process test, especially can't test the electric current in the long-term put procedure of dolly continuously, naturally also just can't carry out long-continued test, also just make production firm be difficult to accurately to know that dolly electric energy of when disturbing (promptly be subjected to various radio unlocking signals for a long time) in the environment of parking lot supports situation the dolly that is placed in the parking lot.
Therefore, how to provide a kind of effective current detecting system,, become the technical task that those skilled in the art need to be resolved hurrily in fact to solve the existing existing shortcoming of method of testing.
Summary of the invention
The object of the present invention is to provide a kind of test system for vehicle quiescent current,, guarantee the quality of vehicle power supply to support the long-term test that continues to vehicle quiescent current.
Another object of the present invention is to provide a kind of test system for vehicle quiescent current, to avoid there is the situation that easily makes operating personnel that Danger Electric shock risk takes place in the existing method of testing.
Reach other purposes in order to achieve the above object, test system for vehicle quiescent current provided by the invention comprises: controlled cell and measuring resistance that the loop of connecting with described vehicle power supply, vehicle electrical loads formation one to be tested is set in vehicle to be tested; Outside described vehicle to be tested, be provided with and be used to control the control module that described controlled cell opens and closes; Outside described vehicle to be tested, the data acquisition module that is used to gather described standard resistor at two terminals voltage is set; And outside described vehicle to be tested, the data conversion module that is used for the data that described data acquisition module is gathered are converted to electric current is set.
Preferable, described controlled cell is a relay.
Preferable, described control module is a switch.
In sum, test system for vehicle quiescent current of the present invention is by being provided with relay and measuring resistance in vehicle, can realize vehicle waken up test, and the long-time test that continues at any time, and then the vehicle power supply through this test is conformed to quality requirements, avoid causing the complaint of human pilot to vehicle mass because of power supply energy consumption deficiency.
Description of drawings
Fig. 1 is the electrical block diagram of test system for vehicle quiescent current of the present invention.
Embodiment
Below will come test system for vehicle quiescent current of the present invention is elaborated by specific embodiment.
See also Fig. 1, test system for vehicle quiescent current of the present invention comprises at least: controlled cell, measuring resistance, control module, data acquisition module, and data conversion module.
Described controlled cell is arranged in the vehicle to be tested, and an end is connected with vehicle power supply by the fuse system of vehicle to be tested, and it can be relay (being signal relay).
Described measuring resistance one end is connected with the described relay other end, the car load electric loading of its other end and described vehicle to be tested (load after the system hibernates) is connected, this shows that described vehicle power supply to be tested, car load electric loading, controlled cell and measuring resistance form a series connection loop.
Described control module is arranged on outside the described vehicle to be tested, is used to control the switching of described controlled cell, and the pull-in winding of one end and described relay is connected, and the other end is connected with the shell fragment of described relay, and it can be switch.
Described data acquisition module is arranged on outside the described vehicle to be tested, is used to gather described standard resistor at two terminals voltage (being the micro voltage collection), and its two ends are connected with the two ends of described measuring resistance respectively.
Described data conversion module is arranged on outside the described vehicle to be tested, be used for the data that described data acquisition module is gathered are converted to electric current to obtain output valve, in the present embodiment, the signals collecting chip that described data acquisition module and data conversion module adopt day to put H8860 and 18946 is finished the function of data acquisition and conversion, wherein, data-switching mainly realizes by software.
In sum, test system for vehicle quiescent current of the present invention can carry out waking up of random computer car load network by relay is set in car, and wakes the test of operating mode up; And can carry out net assessment to the power consumption of the various ECU electronic modules of vehicle; Also can realize simultaneously the long-time test that continues to vehicle quiescent current; Through so test, can guarantee that vehicle under long-term placement situation, also can start success.
The foregoing description just lists expressivity principle of the present invention and effect is described, but not is used to limit the present invention.Any personnel that are familiar with this technology all can make amendment to the foregoing description under spirit of the present invention and scope.Therefore, the scope of the present invention should be listed as claims.
