Abstract
The utility model relates to an analog quantity signal detection device comprising a channel selection part, a channel detection part, and a signal detection part. The channel detection part is disposed between the channel selection part and the signal detection part, and the channel selection part is controlled by a button. The device provided in the utility model has advantages of high efficiency, low costs, easy operation, and ability of facilitating large-scale production.
Description
Technical field
The utility model relates to a kind of instrument control signal supervisory instrument, mainly is that centralized detecting is carried out in the place that is implemented in the instrument control set of signals, belongs to automation field.
Background technology
Concentrate the occasion of using in analog quantity, often need to directly monitor or detect its input and output, especially when signal system breaks down, the detection of analog signals is particularly important, in the prior art, the method for conventional sense mainly contains two kinds: 1, manually utilize multimeter to detect, the method must wait the check man just can detect behind the scene, therefore delay the normal production time, and efficient is low; 2, utilize the isolator with digital display to detect, namely each road signal installs a digital display isolator additional, because the digital display isolator is relatively more expensive, when failsafe, its utilization ratio is very low, so General System does not dispose so in a large number.Therefore, a kind of pick-up unit of exigence solves technical matters of the prior art.
Summary of the invention
The utility model provides a kind of analog signals pick-up unit just for the technical matters that exists in the prior art, this install not only the efficient height and also cost lower, easy operating.
In order to solve the problems of the technologies described above, the technical solution of the utility model is, a kind of analog signals pick-up unit, it is characterized in that this pick-up unit comprises the channel selecting parts, passage detection part and signal detecting part, described passage detection part is arranged between channel selecting parts and the signal detecting part.
Ultimate principle of the present utility model is, the instrument control signal of needs detection, access in order respectively in the utility model device, device is in the energising vacant state at ordinary times, when needs instrument control input, only need channel to channel adapter to choose the passage number of this instrument control signal access, just can carry out correct detection.
The utility model device is divided into three parts: 1, channel selecting parts, these parts adopt the form of the corresponding button of each passage, and when needing to detect respective channel, the button that only need to press this passage gets final product; 2, passage detection part, described passage detection part is the functional block by terminal control independence output terminal.The selected functional block of the utility model is 4016 integrated functionality pieces, signal supervisory instrument is made of two 4016 integrated packages, each 4016 integrated package simple type four passages are arranged, for each passage of integrated package 4016, be similar to an electronic switch, each group analog quantity signal is controlled by two 4016 integrated packages like this, be equivalent to be controlled by two electronic switches respectively, by matching with the channel selecting parts when the channel selecting parts are selected certain passage conducting, then can realize the corresponding passage conducting of 4016 integrated packages, the analog signals of this passage is sent into respectively the signal display part like this; 3, signal detecting part is because pick-up unit technology comparative maturity in the prior art only needs to connect a common analog quantity display device and gets final product.
Description of drawings
Fig. 1 is the pick-up unit configuration schematic diagram;
Fig. 2 is pick-up unit control rough schematic view;
1 is signal display apparatus among the figure; 2 is 4016 integrated controll blocks; 3 is button; 4 analog signalses for detection, A, B, C, D are for controlling respectively the button of four passages, and a, b, c, d are four control ends of 4016 integrated packages among the figure.
Embodiment
In order to deepen that understanding of the present utility model is described further the utility model below in conjunction with accompanying drawing.
Embodiment 1:
Referring to Fig. 1,2, only have easily 4016 integrated packages of 4 passages to describe with one group, comprise two 4016 integrated packages, the output terminal of 4016 integrated packages is wherein carried out short circuit, the input end of another piece 4016 integrated packages is carried out short circuit, with these two integrated package access analog quantity detecting devices, the control end of two 4016 integrated packages is a, b, c, d is in parallel respectively, namely two corresponding input ends of integrated package are to be A by a control knob, B, C, D controls, when control knob A is pressed, the noble potential simultaneously of a control channel in two integrated packages then, the simultaneously conducting of same passage of a control end control in such two 4016 integrated packages, in like manner the instrument control signal by this passage passes through analog quantity detecting device, and other passages still keep realizing cut-off state, signal conflict can not occur.In order to realize that control end is monitored, connect status indicator lamp at each control end.
In the zone that needs analog quantity to detect, at first this device Access Control power supply, different voltage distribution can be carried out in this device inside, for example, pick-up unit partly is alternating current 220V, perhaps direct current 24V, and the control integration block power supply is direct current 5V, after pick-up unit passes into power supply, terminal place at analog input, analog signals is accessed respectively the passage of this pick-up unit, after all signals access this pick-up unit, just can carry out input.This install not only the efficient height and also cost lower, easy operating is convenient to large-scale production and application.
What need instructions is that above-described embodiment only is preferred embodiment of the present utility model, is not used for limiting protection domain of the present utility model, and protection domain of the present utility model is as the criterion with claims.
Claims (6)
