Abstract
The utility model discloses an active multifunctional adapter, which comprises a power supply part, a signal input interface, a signal output interface and a signal protection device. The power supply part comprises two groups of power outputs. The signal protection device is connected between the signal input interface and the signal output interface. The protection device comprises an over-voltage protection circuit and an under-voltage alarm circuit. According to the technical scheme of the utility model, multiple paths of signal switching inputs and outputs are integrated inside the single adapter, so that a to-be-tested sensor arranged on a workbench is free from being individually wired. During usage, a user only needs to connect the above active multifunctional adapter with the to-be-tested sensor through a wire, or connect the active multifunctional adapter with a plurality of sensors to work together. Therefore, the occurrence of connection errors caused by the disorderly and unsystematic condition on the workbench can be effectively reduced. The active multifunctional adapter has the advantages of simple structure, attractive appearance and convenient operation. By means of the active multifunctional adapter, the working efficiency can be effectively improved.
Description
Technical field
The utility model relates to signal converting field, particularly relates to a kind of multifunctional active adapter.
Background technology
At present, no matter be in research and production or business unit, various types of sensor application are very extensive.Particularly in the calibrating sensors of laboratory, owing to generally can calibrate multiple transducers simultaneously.At present in the mode of connection of laboratory calibrating sensors be: together with the signal of each transducer is screwed in by craft with the line of power supply and data acquisition unit respectively with power line, because circuit is various, may cause connection error, loose contact, working site is in disorder, reduces the problem of operating efficiency.This New Active type Multifunctional adapter for pickup has multiple special Wiring port and plug, corresponding one by one, can solve above problem.In addition, in the time that transducer is powered, the variation of external voltage may cause the signal of transducer damage or output error, and institute's overvoltage protection and undervoltage warning function also inserted in this adapter is to overcome this problem.
Utility model content
The purpose of this utility model is to solve above-mentioned existing issue; a kind of Multifunctional adapter for pickup is proposed; by Various types of data input/output port is integrated on same control panel; data are exported by protective device again; by this integrated device; in the time testing, need to, at independent connecting test line, directly just data can not outputed to appointment place by the utility model.
The scheme that the utility model adopts is: a kind of multifunctional active adapter; comprise power unit; signal input interface, signal output interface and signal protection device; described power unit comprises two groups of power supply outputs, is connected signal protection device between described signal input interface and signal output interface.
In technique scheme, described protective device comprises overvoltage crowbar and undervoltage warning circuit.
In technique scheme, described signal input interface comprises the signal input that ten tunnels are different, and one group of power supply is output as wherein five road signal input interfaces provides power supply, and another group power supply is output as remaining Wu road signal input interface power supply is provided.
In technique scheme, in each road signal input, all connect independently voltage protection circuit and undervoltage warning circuit of Guo Yi road.
In technique scheme, the voltage differences of the identical or two groups of power supply outputs of the voltage of described two groups of power supplys output.
The beneficial effects of the utility model are: by implementing the utility model, signal converting input, the output of multichannel can be integrated in a device, on workbench, do not need the independent wiring of transducer to test, only need to this device and tested transducer be linked together with line, or connect multiple transducer co-operation, effectively reduce because working face disorderly and unsystematic causes connecting and made mistakes, this apparatus structure is simple, good looking appearance, easy to operate, can effectively promote operating efficiency.
Accompanying drawing explanation
The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is theory diagram of the present utility model;
Fig. 2 is panel control chart of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises input interface, output interface, is connected to the protective device between input interface and output interface, and is the power supply output of whole device power supply.
Wherein input interface comprises ten road signaling interfaces, input when ten road unlike signals can be provided, and the upper independently protective device of a road that connects of each road signal input, protective device comprises overvoltage crowbar and undervoltage warning circuit.
Power unit adopts the adjustable DC Power supply of external, after power supply access to plant, be divided into two groups of different power output circuits, each Zu Wu road signaling interface input provides power supply, two groups of power supplys are respectively arranged with a master switch, the power supply of each group is divided into again No. five branch circuits, is provided with branch's independent switch on molecular circuit.Like this power supply just simultaneously the signal of Gei Shi road transducer power because power supply is divided into two groups, also can supply with the working sensor of two groups of different rated voltages simultaneously.
As shown in Figure 2, the using method of this active type Multifunctional adapter for pickup: the transducer of needs calibration or use is numbered, corresponding one by one with the wiring interface that signal accesses and power supply picks out in Fig. 2, then the holding wire of each transducer and corresponding the connecting of power line (should be noted positive and negative).Next general supply access in Fig. 2, access is connected with outside regulated power supply with general supply, be adjusted to the current transducer load voltage value of calibrating or using, again the voltage change-over switch in Fig. 2 is screwed to current load voltage value gear (because the transducer rated voltage on market mostly is 10V/12V/16V24V, so be designed to these four kinds herein, here in 8V-30V, can arrange arbitrarily as required), and then according to on-the-spot service condition selection and the signal output interface being connected of data acquisition unit, and connect.Check and errorlessly open master switch and master switch and the Zhong Ge road mains switch in Fig. 2 according to the number of probes using afterwards, indicator light corresponding in use is bright.
Disclosed all features in this specification, except mutually exclusive feature, all can combine by any way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
