Description
Technical field
The present invention relates to a kind of digital force-measuring system, especially a kind of digital force-measuring with portable field attending device
System.
Background technology
By some digital force-measuring sensors, control terminal, dynamometry table top and communication cable etc. combine digital force-measuring system
Constitute.Currently, with Internet of Things and digital informationalized fast development, in dynamometry field it is desirable to force cell and dynamometry system
System is gradually accelerating digitized paces, and force cell and dynamometric system manufacturer develop one after another and be proposed various digital force-measurings
Product sensor and digital dynamometric system, increasing digital force-measuring system is widely used in the various industries of society.
Digital force-measuring system fast development simultaneously, corresponding after-sale service and on-site maintenance mode do not obtain synchronization
Development, still rests on the more primary stage：The information being obtained by control terminal, and by field maintenance person's experience or existing
The substantial amounts of test in field, to carry out the maintenance of fielded system.
But, but in a lot of occasions, current on-site maintenance mode is not enough to complete on-site maintenance work, embody as
Under：
1) when control terminal apart from scale body and sensor farther out (such as larger than 100 meters), be difficult to judge by control terminal
Field condition.The general scale body with each sensor of loading of control terminal is separated, and such as control terminal is positioned over control interior,
It is outdoor that scale body is arranged in control.So, field maintenance person passes through visually to be difficult to while observing control terminal display interface,
The scale body observed and the situation of sensor.Generally require two field maintenance person at the scene, a bit manipulation instrument, a behaviour
Make scale body and sensor, by communication tools such as phones, common cooperation just can complete on-site maintenance work.
2) when communication cable breaks down, such as short-circuit or breaking, system malfunctions be can only see by control terminal and pass
Sensor, and cannot judge is cable fault.Work as certain or some sensor failure, because only identifying on control terminal again
The bus communication address of sensor node, if bus communication address cannot be corresponding with sensor physics position, then by controlling
Terminal can only see system malfunctions, and cannot judge specific fault sensor.In the case of these, on-site service personnel needs
Control terminal is pulled down from fielded system, then is connected with each suspect sensor or suspicious cable respectively, then replaced with spare part
Change each suspect sensor or suspicious cable, progressively reduce suspected fault point range.Waste time and energy and do not say, a lot of situations are to look for
To real trouble point, all of sensor in suspected fault point range and cable have to be replaced by on-site service personnel,
To complete on-site maintenance work, to considerably increase maintenance cost.And whole maintenance process is it is sometimes desirable to a couple of days, a few weeks longer, very
Just can complete to the several months, during this, curstomer's site is in suspended state, bring huge economic loss to client.
3) when sensor node software needs to be upgraded to redaction, control terminal typically cannot be realized.In this case,
On-site service personnel need each sensor pull down from fielded system, and respectively with the equipment such as preprepared PC, pass through
Any special measures connect, and to carry out software release upgrade by special step.Waste time and energy and do not say, client does not allow so to grasp sometimes
Make, also do not allow when the space of weighing platform is disposed with so to operate, such as scale body is embedded in underground or the high-level occasion of frame.
4) some on-site maintenances work, such as field upgrade software, field diagnostic fault etc. is it is desirable to field maintenance person possesses
The technical background knowledge of specialty, but currently most of generic field attendants do not have, and causing on-site maintenance to work cannot
Smoothly carry out.Only wait digital force-measuring system or sensor manufacturer to send professional and technical personnel to scene, maintenance could be carried out
Work, considerably increases the human cost of on-site maintenance work.
5) some digital force-measuring system manufacturer provide remote maintenance to support function, current realization side live dynamometric system
Formula is to access the wide area network of curstomer's site by control terminal, and control terminal is derived from the remote maintenance of manufacturer by wide area network reception
Support.And curstomer's site does not generally possess wan environment, or possess wan environment but client do not allow control terminal access
Client's wide area network is in case leukorrhagia stopping carrys out additional networks expense, thus cannot be carried out the remote maintenance work of digital force-measuring system.
To sum up, existing on-site maintenance mode wastes and substantial amounts of safeguards manpower and maintenance cost, and in a lot of occasions
On-site maintenance work cannot be completed；The specialized capability of field maintenance person is required very high, this requirement is currently difficult to full simultaneously
Foot；Meanwhile, cause curstomer's site to stop work, bring huge economic loss to client.Current on-site maintenance mode is not
Meet dynamometry field digital information demand for development, digital force-measuring system lacks a kind of convenient, fast, real-time, the accurate reality of energy
The device of existing on-site maintenance function, to be used for the thorough unfavorable present situation changing current digital force-measuring system for field maintenance work.
