When PC port 5 carries out data download and system initialization for operating personnel by PC.
Transportation cycle of quarry tipper comprises zero load, loading, delivery and unloading.
Load: start from truck and implement to load in braking, compartment without material and weight detected and increase, end to discharge load braking after and the weight increase detected.
Delivery: start from discharging and load braking and the weight increase detected, end at the compartment and begin lifting.
Unloading: start from the compartment and begin lifting, end at the compartment and fall back on vehicle frame.
Unloaded: as to start from the compartment and fall back on vehicle frame, end to implement to load braking.After loading braking enforcement, weight not detected increases, and complete vehicle curb condition keeps.
Under loading condition, the payload capacity measured value is that display screen 3 shows that reading is not too accurate.When quarry tipper leaves power shovel speed and reaches 3mph, more accurate.Quarry tipper is under steady delivery state, and this value is the most accurate.Described steady delivery state refers to that accelerator pedal is not stepped on, when all brakings all do not apply.
Payload capacity calculation process of the present utility model is as follows:
Consider quarry tipper operating condition and at any time may be because of the car load situation out of service that breaks down, weighing device should possess the ability of autonomous classification running status.Therefore, at first the utility model judges that whether the difference of current calculating gross deadweight and initial dead weight capacity is greater than preset value.If quarry tipper enters light condition.Otherwise, load braking enforcement and otherwise determined that quarry tipper is to load or delivery.
In loading process, the power shovel operating personnel can watch the state of state display lamp 4 in real time, namely based on preassigned allowable value, the loaded material total amount are quantitatively controlled.Do not have lamp bright-can continue to load, less than 85% of nominal load capacity; Amber light is bright-can refill a shovel, between nominal load capacity 85%-95% between; Amber light dodge-can refill half shovel or stop loading, between nominal load capacity 95%-105% between; When red-should stop loads, between nominal load capacity 105%-115% between; Red light dodge-overloads, greater than 115% of nominal load capacity.
Complete loading process or current calculating gross deadweight and implement greater than initial dead weight capacity, loading braking, enter the delivery state.Along with coming into operation of accelerator pedal, electric braking and service braking, when load flowmeter 1 can obtain speed and reaches 3mph and the steady payload capacity under the delivery state.By the detection speed signal, can confirm whether vehicle also is in the delivery state.
When carriage lifting, namely mean the unloading beginning.Otherwise the delivery state keeps.After unloading was completed, weighing device upgraded initial load-carrying value automatically.Transportation cycle begins at this point next time.
For the utility model, also to satisfy following condition:
The dead weight capacity computing formula
front?payload=correction×Δfront?pressure+offset
rear?payload=correction×Δrear?pressure+offset
total?payload=front?payload+rear?payload
In formula: front payload/rear paylod/total payload---forward mounting/rear-mounted/overall load capacity;
Δ front pressure/ Δ rear pressure---forward mounting/rear-mounted current pressure value and initial value poor;
Correction/offset---correction factor/offset.
Only when using the utility model first, initial dead weight capacity numerical value equals the current calculating dead weight capacity of truck, for the original pressure value in computing formula, and the force value that it provides for the suspender pressure transducer 2 that reads at last under calibration condition.
When EEPROM (Electrically Erasable Programmable Read Only Memo) 103 storage spaces are finished using, stored record the earliest will be written.
The above; it is only the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or changed according to the technical solution of the utility model and inventive concept thereof; as use other types microprocessor, storer etc., within all should being encompassed in protection domain of the present utility model.
