Embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
Combination instrument comprises tachometer gage 3, speedometer 4, fuel gauge 5 and water-thermometer 6, according to shown in Figure 1, the utility model automatic detection device comprises the detection tachometer gage, speedometer, fuel gauge and water-thermometer detecting unit 1, this detecting unit is made of four detection modules, be respectively tachometer gage detection module 11, speedometer detection module 12, fuel gauge detection module 13 and water-thermometer detection module 14, the instrument that these detection modules are corresponding with it respectively is connected, the detecting unit output terminal links to each other with controlled processing unit 2, this controlled processing unit comprises memory module 21 and processing module 22, detection module is connected on the processing module, this memory module is connected on the processing module, and be connected on the circuit of each instrument, each instrument is sent the signal that each instrument corresponding sensor of simulation is exported, on memory module, also be connected with tachometer gage, speedometer, fuel gauge, the water-thermometer service data is carried out predefined load module 7.Processing module is connected to display unit, and this display unit is the LCDs on the automobile combination meter panel, and the result after detecting is shown.This pick-up unit carries out opening and closing by ignition switch or mileometer reset key to pick-up unit.
This automatic detection device before use, need pre-set tachometer gage, speedometer, fuel gauge, water-thermometer service data, it is stored in the memory module, these data can just be set constant after pick-up unit production, also a load module 7 can be set on memory module, tachometer gage, speedometer, fuel gauge, water-thermometer service data are reset, to satisfy the requirement that the user detects the different numerical value of instrument.These predefined data can send on the combination instrument when pick-up unit moves, be simulation tachogenerator, speedometer sensor, fuel gauge sensor, the water-thermometer signal of sensor corresponding with combination instrument, making combination instrument that the service data that configures is installed indicates, change by being indicated to 2000 as setting tachometer gage, and then there are 2000 commentaries on classics to be indicated to 0, and so circulation, set one minute 4 times circulations; Set the speedometer indication and be indicated to 80 yards, get back to 0 by 80 yards then, and set one minute 4 times circulations by 0; Set water temperature table, fuel gauge show that resistance is 75 ohm of corresponding lattice numbers.During use, under the automobile ignition switch closed condition, grow by the mileometer reset button after ignition switch is opened 6S, can enter autosensing mode, this moment, memory module sent to each instrument with predefined data, then instrument is indicated according to the service data of setting, monitoring means is monitored the ruuning situation of each instrument simultaneously, then data monitored is sent to processing module, in processing module, the data that monitor and pre-set data are compared, whether there is difference, judges then whether instrument is damaged.As shown in Figure 2, the workflow of tachometer gage and speedometer detecting unit is: open autosensing mode, the detection of tachometer gage and speedometer begins automatically, and both carry out synchronously, detects by the tachometer gage of predefined input signal and the ruuning situation of speedometer separately.Under autosensing mode, if tachometer gage or speedometer can not be according to the preset parameters patterns, indicate or other abnormal occurrencies are arranged, illustrate that then the instrument indication is inaccurate or damaged, otherwise illustrate that then tachometer gage or speedometer are normal.By preestablishing the input parameter of tachometer gage or speedometer respective sensor, phenomenon contrast after carrying out automatic detected artifacts and piloting engine, the supervisory personnel can decision making at once, be the problem or the respective sensor input signal problem of instrument, convenient, fast, deal with problems pointedly.As shown in Figure 3, the workflow of fuel gauge and water-thermometer detecting unit: open autosensing mode, the detection of fuel gauge and water-thermometer begins automatically, both detections are carried out synchronously, count the resistance value of correspondence by detecting two instrument demonstration lattice separately, and show resistance value in former milimeter number LCDs, processing module is compared two resistance values that show on predefined resistance and the instrument then, if variant, illustrate that then the instrument indication is inaccurate or damaged.Otherwise illustrate that then fuel gauge or water-thermometer are normal.After all detection finishes, processing module is presented at the result on the LCDs, as preestablishing the data presented first bit representation tachometer gage, the second bit representation speedometer, the 3rd bit representation water-thermometer, the 4th is the expression fuel gauge, and it is normal for expression to set numerical value 0, and 1 expression damages, and the user is easy to regard to which instrument of judgement place damage by the monitoring result data of observing on the LCDs like this.
