(each amplifier has 8 passages) that big device one passage of sampling observation is carried out.Existence cannot be to all passages
In open circuit that may be present, short circuit and physical channel carry out comprehensively with logical channel corresponding relation mistake etc.
The problem of detection, causes the adverse consequences such as loss of data or error in data to measurement data.
Utility model content
The purpose of this utility model is to provide a kind of strain data collecting device channel-detecting device, is used for
The quality of complete detection acquisition channel.
The technical solution of the utility model is:
A kind of strain data collecting device channel-detecting device, for detecting the break-make of every acquisition channel,
Including measuring cable plug, containing organizing access interface on described measurement cable plug, adopt for access more
Collection passage, often organizes described access interface and is all connected with a measuring resistance and a press button, composition
/ 4th bridge one brachium pontis, its excess-three brachium pontis is passage part to be detected, wherein, described mark
Quasi-resistance is connected in series with described press button, common with one after each described press button
Socket connect, then by cable with measurement equipment be connected.
Optionally, described access interface is the access interface connecting three-wire system strain gauge, on access interface
There are three strain gauge access points.
Optionally, described measuring resistance is 120 Ω.
Optionally, containing 16 groups of access interface on described measurement cable plug.
Having the beneficial effects that of strain data collecting device channel-detecting device provided by the utility model,
The most once the strained channel of a group (16 paths) is detected, it is possible to the most right
Short circuit that may be present, open circuit and physical channel and the problem of logical channel corresponding relation mistake in passage
Detect, and with low cost, be convenient for carrying, simple to operation.

Detailed description of the invention
Clearer for the purpose making this utility model implement, technical scheme and advantage, below in conjunction with
Accompanying drawing in this utility model embodiment, is carried out more the technical scheme in this utility model embodiment
Detailed description.In the accompanying drawings, the most same or similar label represents same or similar unit
Part or there is the element of same or like function.Described embodiment is a part of embodiment of the present invention,
Rather than whole embodiments.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to
For explaining this utility model, and it is not intended that to restriction of the present utility model.New based on this practicality
Embodiment in type, those of ordinary skill in the art are obtained under not making creative work premise
Every other embodiment, broadly fall into this utility model protection scope.Below in conjunction with the accompanying drawings to this reality
It is described in detail by novel embodiment.
1 pair of this utility model strain data collecting device channel-detecting device does into one below in conjunction with the accompanying drawings
Step describes in detail.
The strain data collecting device channel-detecting device that this utility model provides, is used for detecting every and adopts
The break-make of collection passage, this device strain measurement method based on 1/4th bridges, including measuring cable
Plug 4, measurement cable plug 4 is selected according to actual needs and is used for connecting three-wire system strain containing 16 groups
The plug of the access interface 1 of meter, the access interface of above-mentioned three-wire system strain gauge has three strain gauges connect
Access point 11,12,13, often group access interface 1 all accesses one for the 120 of equivalent 120 Ω strain gauges
Ω measuring resistance 2, and one press button 3 of access of connecting, form 1/4th bridge one
Brachium pontis, its excess-three brachium pontis is passage part to be detected, with one after each press button 3
Common socket connects, then is connected with the equipment of measurement by cable 5.Every 1/4th bridges are used for
Detect a passage, thus the detection of 16 paths can be carried out every time.Utilize the break-make of press button 3
Control whether 120 Ω measuring resistances 2 access bridge, and then the quality of detection strained channel.
In specific operation process, 16 passages in strain data collecting device channel-detecting device are surveyed
Amount cable plug, is inserted into collecting device end cable socket, is then turned on collecting device, the most successively
16 press buttones of opening detecting device, it is possible to select to open the switch of certain passage according to actual needs,
If passage is no problem, then collecting device display lamp can extinguish.Plug is pulled up in one group of detection end, then
Carry out the differentiation of next group passage.And then can be comprehensively to short circuit that may be present in passage, open circuit
And the problem of physical channel and logical channel corresponding relation mistake detects.
The above, detailed description of the invention the most of the present utility model, but protection model of the present utility model
Enclose and be not limited thereto, the skill that any those familiar with the art discloses at this utility model
In the range of art, the change that can readily occur in or replacement, all should contain at protection domain of the present utility model
Within.Therefore, protection domain of the present utility model should be as the criterion with described scope of the claims.
