Fig. 2 is host computer flow chart of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-2 is referred to, a kind of stacked switch electrical property detector, it is high-precision mainly by technical grade control computer
Spend AD data acquisition array modules, current control metal-oxide-semiconductor array module, electrical resistance collection array module composition.Host computer passes through work
Industry level control computer control electric current controls metal-oxide-semiconductor array module and electrical resistance collection array module to set the collective of each passage
Function, then by controlling high-accuracy data acquisition array module to be acquired processing to each passage, show real time value and sentence
Whether fixed output quota product are qualified.
Main feature of the present invention：
1. instrument provides A 16 binding posts of group, 16 binding posts of B groups, AB can set arbitrarily collocation by upper computer software
Sense channel, and the passage concrete function is set（Detect voltage, resistance, backlight electric power is provided）.Inspector can random wiring, lead to
Crossing host computer sets function machine examination criteria i.e. detectable.
2. instrument has port inspection function, inspector accesses stacked switch, and upper computer software can be automatically reminded to inspector
Carry out port inspection operation.Instrument can be examined to the linking relationship between each binding post in port of port B groups 16 of A groups 16
Look into, and can recognize that within 15K resistances and be considered as linking status.This function can effectively detect to whether there is inside stacked switch
Short circuit, rosin joint connect phenomena such as welding.Such as：Stacked switch internal circuit board has short weldering, or has foreign matter to cause lightly conducting in structural member
Phenomena such as less than 15K resistances, master system directly can judge AxAy by port inspection, and Axby, BxBy ports are short-circuit,
Product is unqualified.
3. instrument has state learning functionality, inspector can correctly combine stacked switch conducting shape by host computer
State learns to be saved in host computer preservation product in advance, and upper computer software can contrast with learning state automatically in detection, judge
Whether whether stacked switch state is correct, qualified from combination switch.This function can effectively avoid occurring scruff inside stacked switch, lead
Line, structural member link phenomena such as.Such as：Left steering switchs, and right turn switch can not possibly simultaneously turn on, if having inside stacked switch
Structural member links, and scruff etc. causes to simultaneously turn in left and right turn switch placement process, and master system can automatic identification shape
State erroneous products are unqualified.
4：Upper computer software can directly be shown by display screen each switch currently turned on icon in kind and
Turn-on voltage, resistance value.And can be automatically reminded to whether inspector's product is qualified, and port inspection short-circuit conditions, combination turns on
State, whether there is missing inspection, and the unqualified reason of substandard product.Upper computer software system high account can add preservation product
Convenient management, it is i.e. detectable that inspector need to only select product type.Upper computer software system provides query statistic function, can be at any time
Inquire about detection history and qualified unqualified quantity.
The present invention operation principle be：The present invention shown in Fig. 1 passes through the serial communication mould of standard 232 by industrial control computer
Block is communicated with ARM controller.ARM controller can directly control high-precision AD acquisition module, AD channel selectings array, program control
Current source, current channel selection array, resistance via selection array, each array pass through protection circuit parallel connection road AB port connections
On post, this acquisition method is using Kelvin's four-line measurement method, it is possible to reduce line loss, device error etc..Inspector is led to
Cross display and product related information parameter testing passage and examination criteria are directly set, the mould that communicates is passed through by industrial control computer
Block is sent to ARM controller, can open corresponding sense channel according to the related channel array of configuration by ARM controller, control
High-precision AD acquisition module gathered data processed is sent to industrial control computer and analyzed and processed by upper computer software.Judge production
Whether product close rule.
Inspector shown in Fig. 2 selects product type to start to detect by software, and system can carry out port inspection operation first
If inspection is qualified.Program will carry out the detection of voltage resistance value to each passage of product and be combined switch-turn-ON states detection simultaneously
If voltage resistance value meets examination criteria and stacked switch conducting state is coincide with the state learnt, each Channel Projects detection is treated
After the completion of system can automatic decision product it is qualified.If interiors of products has situations such as short-circuit conditions, short weldering, the unqualified meeting of system inspection
It is unqualified directly to eject result access port short circuit product；If product poor contact of contacts causes conduction voltage drop is overproof not meet
Standard or interiors of products electricity group are not soldered properly resistance error system according to regulation resistance and can directly display current channel
Voltage resistance value simultaneously judges that product dropping resistor value is overproof, and product is unqualified；If phenomena such as linkage be present in interiors of products structural member,
The combination conducting state that system can learn with current production contrasts, and system can directly display its wrong conducting state and judge to produce
Product are unqualified.If a certain switch of product damages or a certain function of inspector there is not detecting system directly to prompt this missing inspection product not
It is qualified.
