2. A trolley based casting metering method as claimed in claim 1, wherein there are a plurality of said trolleys, each of said trolleys having said third location disposed thereon.
3. The trolley-based casting metering method of claim 1, further comprising, after the third position is determined, the control unit reading the weight of the ladle after a hold time set by the control unit; recording a start time of casting, an end time of casting, a weight of the ladle at the start time point of casting, and a weight of the ladle at the end time point of casting at the start time point of casting; Casting time and casting weight were calculated.
4. A trolley based casting metering method as claimed in claim 3, wherein the method of the control unit reading the weight of the ladle comprises, at a frequency, continually reading and comparing the weight of the current ladle with the weight of the previous ladle read; if the difference between the weight of the previous ladle and the weight of the current ladle exceeds the range set by the control unit, judging that casting is started, otherwise, not starting casting.
5. The trolley-based casting metering method as claimed in claim 4, wherein the method of the control unit reading the weight of the ladle further includes recording the time at which the corresponding weight is recorded while each time the ladle weight data is read.

Description

Casting metering system based on lifting device and metering method thereof Technical Field The invention relates to the technical field of electric technology, in particular to a control method for working procedure operation in industrial production. Background At present, for a casting enterprise adopting crown block casting, the casting time is manually calculated by a worker pinching a stopwatch, when casting starts, a stopwatch start button is clicked, when casting ends, a stopwatch end button is clicked, and the time difference is the casting time. The casting weight is that before casting, a weight value is manually recorded, and after casting is finished, a weight is recorded again, and the difference is the casting weight. The manual timing of workman not only can't accurate timing, still needs subsequent data entry simultaneously, has not only increased the operation link, still needs special operating personnel to develop corresponding work, still easily forms the information island in addition, is unfavorable for the informatization transformation of casting enterprise. Disclosure of Invention In view of the problems that in the prior art, casting operation cannot accurately measure casting time and casting weight and the problems that a casting ladle is difficult to position and casting digital management capability is weak in a casting process, the casting metering system based on the lifting device and the metering method thereof are provided, and whether a casting crane is located in a casting area or not is judged through acquired data, so that casting time and casting weight are calculated, and the effect of improving accuracy of data acquisition of the casting time and the casting weight is achieved. The casting metering system based on the lifting device comprises a first position, a second position, a third position and a control unit, wherein position detection devices are arranged on the first position, the second position and the third position, the position detection devices are electrically connected with the control unit and used for realizing the transmission of data and information among the positions, the third position is arranged on the lifting device, the first position and the second position are arranged outside a casting area, the horizontal distance between the first position and the second position and the edge of the casting area is k, the distance between the first position and the second position is c, the third position is judged to be in the specific position of the casting area through the first position and the second position, and the purpose of positioning the third position, namely the purpose of positioning the lifting device is realized, so that the specific position of an object lifted by the lifting device is determined. Preferably, the position detecting device may be various distance measuring devices or instruments such as a UWB positioning base station, a laser position detector, etc. for measuring the distance between the first position, the second position, and the third position.
