Description

The desk-top scale of electronics with fault detection capability

Technical field: the utility model relates to the desk-top scale of a kind of electronics.

Background technology: at present, the desk-top scale of the electronics that uses in real productive life, its mechanical part mainly are made of the LOAD CELLS of weighing table, one group of unitor and respective numbers; Its electric part mainly is made of summer that is connected with this group LOAD CELLS and the weighing instrument of its rear end.Its principle of work is, weighing table passes to corresponding LOAD CELLS in the small movements of three-dimensional with the weight information of its object by one group of unitor, each LOAD CELLS becomes weight information into electric signal, send summer respectively to by signal-transmitting cable again, overall treatment by summer sends its consequential signal to weighing instrument, finally will represent the electric signal of weight to become the discernible shows signal of people, to finish the weighing process of object by weighing instrument.Practice shows that the desk-top scale of this electronics often breaks down and influences measuring accuracy, traces it to its cause nothing more than two aspects, and one is the reason of mechanical aspects, mainly be since unitor in the super range motion of a certain direction of three-dimensional or do not move and cause; Another is the reason of electric aspect, mainly is that the damage owing to some LOAD CELLS causes work undesired.The job failure of the desk-top scale of electronics can not look down upon, and it had both influenced the normal use of weighing apparatus, also influences normally carrying out of transaction simultaneously, even causes economic dispute.

The utility model content: task of the present utility model is: a kind of desk-top scale of electronics that has fault detection capability itself is provided, and it both can detect the three-dimensional motion of weighing platform in work, can monitor in real time LOAD CELLS again.Its technical solution is: a kind of desk-top scale of electronics with fault detection capability, comprise the mechanical part that the LOAD CELLS by weighing table, one group of unitor and the respective amount that is connected with unitor constitutes, the electric part that constitutes by the weighing instrument of the summer that is connected with each LOAD CELLS and its rear end, it is characterized in that: below weighing table, be provided with the displacement transducer on three-dimensional, and be provided with the LOAD CELLS monitor and be connected with each LOAD CELLS.Here said LOAD CELLS monitor is to have multichannel input and the voltage table of exporting.Compared with prior art, advantage of the present utility model mainly is: 1. owing to be provided with the displacement transducer of three-dimensional on weighing table, therefore when finding that by displacement transducer the excessive or too small appearance of its displacement on certain direction is undesired, can point out, so that in time change unitor, thereby can guarantee the weighing platform operate as normal from mechanical aspects.2. because the setting of LOAD CELLS monitor, can monitor the duty of each LOAD CELLS at any time, therefore, when finding that by voltage signal certain LOAD CELLS work is undesired, can in time change LOAD CELLS, thereby aspect electric, guarantee the weighing platform operate as normal.3. the utility model is simple in structure, implements easily displacement transducer wherein and be prior art as the multichannel input and output voltage table of LOAD CELLS monitor.

Description of drawings: Fig. 1 is mechanical part structural representation of the present utility model (is example with one group of 4 LOAD CELLS).

Fig. 2 is and the corresponding electric part structural representation of Fig. 1.

Embodiment: as shown in Figure 1, a kind of desk-top scale of electronics that the utility model provides with fault detection capability, its mechanical part mainly is made of the LOAD CELLS 2 of weighing table 1, one group of unitor 3 and the respective amount that is connected with unitor 3, it is characterized in that being provided with on weighing table 1 three displacement transducers, they are mounted in Y-axis displacement transducer 4, Z axial translation sensor 5 and X-axis displacement transducer 6 below the weighing platform respectively.The quantity of said here one group of unitor 3 can be 4,6,8,10 or 12 according to the size of weighing platform.As shown in Figure 2, the electric part of the desk-top scale of this electronics mainly by constituting by the weighing instrument 8 that cable is connected with its rear end with summer 7 that each LOAD CELLS 2 is connected respectively, is characterized in that it is provided with LOAD CELLS monitor 9 and is connecting each LOAD CELLS 2.Here said LOAD CELLS monitor 9 can serve as with having the voltage table of multichannel input with output.
