Abstract
The utility model discloses a junction box for a digital sensor, relates to a digital sensor connecting device, and mainly solves the problems that the conventional digital junction box has instable signals, is troublesome to address and is inconvenient to detect problems. The junction box comprises a shell, a printed circuit board, a digital weighing instrument interface, digital sensor interfaces and an integrated circuit chip, and is characterized in that: the printed circuit board is fixed in the shell; the digital weighing instrument interface is formed on the outer side of the printed circuit board; a plurality of digital sensor interfaces are uniformly distributed on the middle part of the printed circuit board; each digital sensor interface is connected with a dial switch and an LED indicating lamp; and the dial switch, the LED indicating lamp and the integrated circuit chip form a circuit. The junction box can connect digital sensors with inconsistent electric properties in different batches, and can realize single addressing function when connecting a plurality of digital sensors; and when a digital sensor is failed, the circuit can be quickly switched on or off through the dial switch, and the digital sensor is not needed to be frequently changed.
Description
Technical field
The utility model relates to a kind of digital sensor coupling arrangement, specifically a kind of digital sensor terminal box.
Background technology
At present, existing digital terminal box is a simple RS-485 bus, does not have processing such as level conversion in the circuit.If the digital sensor electric property that connects on the digital terminal box certain digital sensor communication part electric property inconsistent or that link together descends, to cause the data-signal instability on the digital terminal box RS-485 bus, cause this RS-485 bus to use, and present digital terminal box is if connect many digital sensors simultaneously, when being addressed, can not use by digital sensor single function that only addresses, adopt the bus addressing after can only obtaining the identification number of every digital sensor, present digital terminal box does not have the data stream indicating device yet, and whether data stream exists and can't observe intuitively.
The utility model content
The purpose of this utility model is to provide a kind of digital sensor terminal box, solves the problem of existing digital terminal box jitter, addressing trouble and detection problem inconvenience.
The technical scheme that its technical matters that solves the utility model adopts is: the digital sensor terminal box, comprise housing, circuit printing plate, digital weighing instrumentation tap, digital sensor interface and integrated circuit (IC) chip, it is characterized in that, circuit printing plate is fixed in the housing, the outside of circuit printing plate is provided with the digital weighing instrumentation tap, be evenly equipped with a plurality of digital sensor interface at the middle part of circuit printing plate, each digital sensor interface all is connected with toggle switch and LED light, described toggle switch and LED light and integrated circuit (IC) chip forming circuit; RS-485 signal on the described digital sensor interface is the Transistor-Transistor Logic level signal through circuit conversion, be one road Transistor-Transistor Logic level signal by logical circuit with the Transistor-Transistor Logic level signal integration on each road then, this road Transistor-Transistor Logic level signal enters the digital weighing instrumentation tap again after circuit conversion is the RS-485 signal; Described toggle switch control figure sensor interface is connected and disconnection with the digital weighing instrumentation tap.
The beneficial effects of the utility model are: the inconsistent digital sensor of different batches electric property can be linked together; Can when connecting simultaneously, realize by many digital sensors single function that only addresses; When breaking down, can diagnose that digital sensor to break down by quick connection of toggle switch or disconnecting circuit, and needn't frequently change digital sensor.
Description of drawings

Fig. 2 is a structured flowchart of the present utility model.
Among the figure: 1 housing, 2 circuit printing plates, 3 digital weighing instrumentation taps, 4 digital sensor interface, 5 integrated circuit (IC) chip, 6LED pilot lamp, 7 toggle switchs.
Embodiment
As Fig. 1, shown in Figure 2.The digital sensor terminal box, comprise housing 1, circuit printing plate 2, digital weighing instrumentation tap 3, digital sensor interface 4 and integrated circuit (IC) chip 5, circuit printing plate 2 is fixed in the housing 1, the outside of circuit printing plate 2 is provided with digital weighing instrumentation tap 3, be evenly equipped with a plurality of digital sensor interface 4 at the middle part of circuit printing plate 2, RS-485 signal on the digital sensor interface 4 is the Transistor-Transistor Logic level signal through circuit conversion, be one road Transistor-Transistor Logic level signal by logical circuit with the Transistor-Transistor Logic level signal integration on each road then, this road Transistor-Transistor Logic level signal enters digital weighing instrumentation tap 3 again after circuit conversion is the RS-485 signal.Each digital sensor interface 4 all is connected with toggle switch 7 and LED light 6, described toggle switch 7 and LED light 6 and integrated circuit (IC) chip 5 forming circuits, this circuit can with many full duplex RS-485 digital sensors by digital sensor interface 4 be connected to digital weighing instrumentation tap 3 and with the communication of digital weighing instrument, toggle switch 7 control figure sensor interfaces 4 are connected and disconnection with digital weighing instrumentation tap 3.
Digital weighing instrumentation tap 3 connected digital weighing instrument when the numeral terminal box was applied in the weighing apparatus system, digital sensor interface 4 connects digital sensor, when weighing instrument sends out data, corresponding LED light 6 will be glimmered, all toggle switchs 7 need push the ON shelves, when every digital sensor sends out data, corresponding LED light 6 will be glimmered; Toggle switch 7 pushes the OFF shelves, and corresponding LED light 6 will can not glimmered.Whether can judge digital sensor work by 6 flickers of observation LED light unusual; Can conducting or disconnect corresponding digital sensor circuit by toggle switch 7, needn't repeat the wiring of dismounting sensor when like this sensor being overhauled.
