Description
Technical field
The utility model relates to automotive electrical system, be specifically related to a kind of scoring system recording the diesel engineering vehicle engine operating time.
Background technique
Engineering vehicle needs to detect and record the operating time of motor, existing technology is generally by oil pressure sensor record, oil pressure sensor ground connection when engine operation, just can record, but its shortcoming is if oil pressure sensor is normal close type, just need to connect normally closed relay, but after gross vehicle power switch is closed, normally closed relay has not just worked, work will be shown always, in order to solve the problem, design a kind of novel scoring system for recording the diesel engineering vehicle engine operating time or necessary.
Model utility content
For the deficiency that prior art exists, the utility model object is to provide a kind of scoring system recording the diesel engineering vehicle engine operating time, structure is simple, reasonable in design, can operating time of recording engine accurately and effectively, practical, reliable and stable, be easy to promote the use of.
To achieve these goals, the utility model realizes by the following technical solutions: a kind of scoring system recording the diesel engineering vehicle engine operating time, comprise generator, recording equipment, storage battery, AC-DC conversion module, relay and total power switch, the positive terminal of the positive pole termination storage battery of generator, the positive terminal of recording equipment, the negative pole termination vehicle body of generator, the coil of the positive terminal contact relay of storage battery is to vehicle body, the negative pole termination total power switch of storage battery is to vehicle body, generator also connects AC-DC conversion module, AC-DC conversion module is connected on vehicle body, the contact of the other end contact relay of AC-DC conversion module is to the positive terminal of recording equipment, the negative pole end of recording equipment is connected to the negative pole end of storage battery.
As preferably, the neutral line of the ac input end sending and receiving motor of described AC-DC conversion module, the DC output end of AC-DC conversion module passes through one end of the normally opened contact of detection line contact relay, and the other end of relay normally open contact is connected with the call wire of recording equipment.
The beneficial effects of the utility model: rational in infrastructure, can record the operating time of statistics motor accurately and effectively, practical, reliable and stable.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is circuit diagram of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of scoring system recording the diesel engineering vehicle engine operating time, comprise generator 1, recording equipment 2, storage battery 3, AC-DC conversion module 4, relay 5 and total power switch 6, the positive terminal of the positive pole termination storage battery 3 of generator 1, the positive terminal of recording equipment 2, the negative pole termination vehicle body 7 of generator 1, the coil of the positive terminal contact relay 5 of storage battery 3 is to vehicle body 7, negative pole termination total power switch 6 to the vehicle body 7 of storage battery 3, the neutral line 8 of generator 1 connects the ac input end of AC-DC conversion module 4, AC-DC conversion module 4 is connected on vehicle body 7, the DC output end of AC-DC conversion module 4 passes through normally opened contact one end of detection line 9 contact relay 5, the other end of relay 5 normally opened contact is connected with the call wire 10 of recording equipment 2, the negative pole end of recording equipment 2 is connected to the negative pole end of storage battery 3.
This embodiment is by detecting the neutral line 8 output voltage of the generator 1 of transmission together with motor, and convert direct current to, recording equipment 2 reads this galvanic time of delivery, thus the operating time of recording engine; Due to vehicle band total power switch, after gross vehicle power switch 6 is closed, full car will be with positive pole electricity, the motor detection line 9 that AC-DC conversion module 4 arrives recording equipment 2 is again transferred to by the neutral line 8 of generator 1, constitute a loop by recording equipment 2 to the negative pole of storage battery 3, vehicle will be shown like this in work always.
This embodiment by adding a normally closed relay 5 in the middle of detection line 9, and when under the state that total power switch 6 is in closedown, relay 5 does not work, and detection line 9 is in turnoff state, and recording equipment 2 can't detect voltage and then not thinks to work; Under total power switch 6 is in the state opened, relay 5 works, and detection line 9 is connected with the neutral line 8 of generator 1, but now opens in circuit due to total power switch 6 and just there is not telegram in reply, and after the neutral line 8 and vehicle ground, detection line 9 does not have voltage yet; When after engine start, the neutral line 8 has voltage to export by producing voltage after linkage record equipment 2, and at this moment the generation time of recording equipment 2 recording voltage adds up the operating time of motor.
This embodiment is used for the detection of Engineering vehicle motor operating time and the record of diesel band total power switch, can operating time of accurate recording motor, practical reliable, has wide market application foreground.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
