The technical solution of the utility model is: a kind of low pressure oil way real-time monitoring system, comprises the pressure transducer detecting secondary filter fuel inlet place oil circuit pressure value, the entire car controller, the alarm that are compared by the preset pressure value in described oil circuit pressure value and entire car controller; Pressure transducer is arranged on secondary filter, and output terminal is connected with entire car controller input end; Entire car controller controls alarm equipment alarm according to comparative result.
Further, pressure transducer and entire car controller are electrically connected.
Preferably, alarm is phonetic alarm or automobile instrument panel.
Preferably, a kind of low pressure oil way real-time monitoring system also comprises fuel temperature sensor and speed probe, and fuel temperature sensor is arranged on the return line of engine body, and output terminal is connected with the input end of entire car controller; Speed probe is installed on the engine, and output terminal is connected with the input end of entire car controller; Entire car controller is according to the fuel oil temperature value collected and engine speed value determination preset pressure value.
The utility model provides a kind of automatical control system, comprises above-mentioned low pressure oil way real-time monitoring system.
The utility model also provides a kind of automobile electrically-controlled motor, comprises above-mentioned automatical control system.
A kind of low pressure oil way real-time monitoring system of the present utility model, automatical control system and automobile electrically-controlled motor, there is the pressure transducer be arranged on secondary filter, the oil circuit pressure value at secondary filter fuel inlet place can be detected and this oil circuit pressure value is exported to entire car controller, the oil circuit pressure value collected and preset pressure value compare by entire car controller, when oil circuit pressure value is different with preset pressure value, vehicle control unit controls alarm equipment alarm.The utility model structure is simple, efficiency is high, monitoring medium tache is few, changes less to the oil circuit of electric-control motor, can carry out the repacking upgrading of automobile easily; And pressure transducer detects the oil circuit pressure value at secondary filter fuel inlet place, realize monitoring while strainer and secondary filter by a pressure transducer, deft design, holistic cost is cheaper, is suitable at automobile electrically-controlled engine art large-scale promotion application.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the utility model embodiment one.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Embodiment one:
As shown in Figure 1, a kind of low pressure oil way real-time monitoring system, comprise pressure transducer 1, entire car controller, phonetic alarm, pressure transducer 1 is arranged on secondary filter 2, for detecting the oil circuit pressure at secondary filter 2 fuel inlet place 3, and oil circuit pressure value is exported to entire car controller; Entire car controller comprises processor, pressure setting unit, and processor electrical connection pressure transducer 1, reads the oil circuit pressure value that pressure transducer 1 sends in real time, and pressure setting unit is used for setting and storing preset pressure value.The oil circuit pressure value of reading is compared with preset pressure value by the processor of entire car controller, obtains the working state of whole low pressure oil way, and controls phonetic alarm warning according to comparative result.Secondary filter 2 is connected with strainer 4 by oil line pipe, and fuel oil enters secondary filter 2 through oil line pipe from the fuel inlet 3 of secondary filter 2 after filtering from strainer 4.
When the oil circuit pressure value that pressure transducer 1 detects is higher than preset pressure value, it is generally acknowledged that now secondary filter 2 blocks, now vehicle control unit controls phonetic alarm is reported to the police, the sound that phonetic alarm sends " fuel pressure is high ", or do not send the sound of " fuel oil temperature is high " but time of fire alarming is longer, remind related personnel to check secondary filter 2 or more renew cartridge.
When the oil circuit pressure value that pressure transducer 1 detects is lower than preset pressure value, it is generally acknowledged that now oil line pipe has leakage or strainer 4 to have blocking, now vehicle control unit controls phonetic alarm is reported to the police, the sound that phonetic alarm sends " fuel pressure is low ", or do not send the sound of " fuel oil temperature is low " but time of fire alarming is shorter, remind related personnel to check strainer 4 and oil line pipe, carry out corresponding more renew cartridge or patch work.
Preferably, the fuel temperature sensor be arranged on engine body return line exports fuel oil temperature value to entire car controller, installation speed probe output engine tachometer value is on the engine to entire car controller, a series of fuel oil temperature value, engine speed value, preset pressure value are set in advance in entire car controller, entire car controller is according to the fuel oil temperature value collected and engine speed value, with existing lookup table mode determination preset pressure value, without the need to artificially changing and reseting preset pressure value, improve system accuracy and efficiency.
