In a specific embodiment of the present utility model, the quantity of described first sensor 41 is two, and the quantity of described second sensor 51 is two.
In a specific embodiment of the present utility model, described first sensor 41 and described second sensor 51 all adopt axial pin type sensor.
Preferably, described intelligence instrument 1 comprises microprocessor 11, display device 12 and signalling channel 13, and described communication bus 2 is connected with described microprocessor 11 by described signalling channel 13, and described microprocessor 11 is connected with described display device 12.In a specific embodiment of the present utility model, described signalling channel 13 adopts the RS232/485 converter, and described display device 12 is CRT monitor.Microprocessor 11 is that CPU is the core of intelligence instrument 1; CRT monitor shows each information of intelligence instrument 1, and accepts operating personnel's operational order; RS232/485 is the signalling channel of the first sensor 41 and second sensor 51, gathers their signal.
In a specific embodiment of the present utility model, described intelligence instrument 1 also comprises I/O port one 4, and described I/O port one 4 is used to connect miscellaneous equipment.Such as host computer, thereby the signal of intelligence instrument 1 is outputed to host computer.
In practical application in the past, weighing shows that console panel is bulky, function is many, and equipment is also a lot; Present intelligence instrument 1 is the specialized equipment that is exclusively used in weighing system, and this intelligence instrument 1 is designed to the multivariate input mode, and minimizing dish dress metered quantity is simplified the instrument structure of weighing system; In addition this intelligence instrument 1 is designed to the menu mode mode of operation, so the native system device is simple to operate, simple in structure, function is special-purpose.
When the utility model is installed, direction along ng a path, two first sensors, 41 front and back of first sensing unit 4 are installed in wherein on the track, at interval suitable distance between this two first sensor 41, two first sensors, 51 front and back of single 5 yuan of second sensing are installed on another track, distance at interval suitably between this two second sensor 51 is symmetrical arranged with first sensor 41 and gets final product.
During use, opening power, when hot-metal ladle and carriage (comprising the molten iron torpedo tank car) or ladle car are parked on the appointed positions, on the rail of each wheel below two sensors are arranged all, under molten iron or the effect of molten steel weight, the sensor under corresponding each wheel produces and the corresponding simulating signal of weight.The wheel quantity of hot-metal ladle and carriage (comprising the molten iron torpedo tank car) or ladle car is generally 4 to 32 (different vehicles, its wheel quantity differences), so the quantity of sensor is also different.The simulating signal of sensor converts digital signal to by first A/D converter 42 and second A/D converter 52 then, enters intelligence instrument 1 by communication bus 2 then.According to the design feature of hot-metal ladle and carriage (comprising the molten iron torpedo tank car) or ladle car, mean allocation is to wheel basically for its complete vehicle weight, so the signal of each sensor is all within certain scope.Therefore intelligence instrument 1 carries out according to the signal of each sensor: intelligent work such as data acquisition, state judgement, coefficient revisal, the corresponding weight signal of output and molten iron or molten steel then.
