Description
Technical field
The present invention relates to the detection dress of a kind of detection device, system and its detection method, more particularly to a kind of MIFI systems
Put, system and method.
Background technology
MIFI (MobileWIFI, mobile WIFI) is a kind of portable wideband wireless device, it collects modem, route
, internal modem can access wireless signal for device and access point three function, as cdma network, GSM, WCDMA or
LTE radio data networks, internal router can share this connection between multiple users and wireless device.MIFI is equivalent to one
The router that mobile network shares, using MIFI products by the data network set meal of user with 802.11b/g/n standard WiFi nets
The form of network is shared out, can realize building for WiMAX LAN, at present, MIFI by particular network in any place
The application of product has been popularized among the life of people.
Meanwhile with the popularization and popularization of MIFI products, in actual application process, carrier market, channel, electric business
Market and many terminal users feed back the problem of many bad existing for MIFI products, and power down of such as starting shooting, can not recover
The problem of influence users such as factory is set, system configuration parameter is lost, system starts exception, WEB page can not enable use.
Therefore, domestic many MIFI productions manufacturer, operator formulate one after another corresponding test specification, manual testing and
Standard carries out checking in terms of quality and management and control.As China Telecom's LTE terminal test method-MIFI terminals now net test point
Volume, China Mobile TD custom terminal product white paper etc..However, MIFI products such as detect it is lack of standardization, not in place, then cannot be compared with
The bad problem of Check System well, critical defect that system is hidden, major defect are such as left used to factory, market or terminal
Family, then influence whether product normal production, cannot normal list marketing, enterprise faces product and is called back and enterprise's revenue decline
Risk hidden danger, it is serious to damage corporate reputation and brand image.
The system performance detection of MIFI products, it is necessary to meet two requirements：First, regulation accordance (such as meets CTA regulations
Authentication requesting)；Second, meet the usage scenario and custom of user, as cell domestic consumer is also registering one's residence without deployment WiMAX
Scene in, it is necessary to consider and solve the demand that user is surfed the web by WiFi terminal whenever and wherever possible indoors, and medium and small enterprise
Industry, restaurant, coffee-house, self-employed entrepreneur have the characteristics that user is more, mobility is strong, business demand is big, terminal form is more, it is necessary to
The demands such as WiFi accesses, online, fixed line, fax sending and receiving are solved, campus number of users is more, data traffic requirement is big, mainly includes

Fig. 1 is the system architecture diagram of the detecting system of existing MIFI systems, and the power supply of MIFI systems 101 is passed through matching by it
Power supply adaptor be connected on the alternating current steady voltage plug 102 of 220V/50Hz, so can give MIFI systems provide a stabilization
Power supply, the energization performance detection then booted up by artificial manual intervention, shut down, it is achieved thereby that the performance of power on/off
Detection；The detection device connects MIFI systems 101 using comprehensive instrument 103, and the performance detection of voice transfer is carried out for simulating, with
Just the speech quality of MIFI systems is confirmed；Then it is connected with MIFI systems 101 with wireless network card 104, is thus can confirm that
The wireless performance of MIFI systems, function.
As it can be seen that the detection scheme of existing MIFI systems, it is necessary to tester by manually being tested, a side
Face, since the performance test of MIFI generally requires to carry out the test of more number (such as more than 1000 times), by this artificial
The mode of manual test causes the waste significantly of human resources, and extends the unnecessary testing time；On the other hand, due to
The hit of power supply is all completed within the Millisecond time, causes precisely to be surveyed during manually being tested
Examination；In addition, or existing detection scheme is detected just for some function in system, or just for some mould in system
The index parameter of block is detected, this serial detection method, it is impossible to preferably assesses the overall performance of MIFI systems, also
Detection cycle can be caused to extend, influence the development progress and detection efficiency of product.

(1) existing MIFI system detecting devices lack flexibility, and Function detection is single and non-automated realizes detection operation.
Break-make electrical property such as switching on and shutting down needs artificial manual operations to realize, thus expends a large amount of detection times, and take manpower
Cost, and detection efficiency is low, in addition, the detection method of the prior art has all uniformly fixed, it is impossible to carry out free adjustment, freedom
Selection, function lack the leeway of selection and expand space using above there is certain limitation, such as do the break-make electrical property inspection of randomness
Survey just can not preferably meet testing requirements；
(2) the performance reliability detection of existing MIFI systems, the performance detection being all limited under normal temperature state, it is impossible to compared with
Various varying environments used by a user are covered well, such as high-temperature work environment, low-temperature working environment, hot and humid environment,
This 4 kinds of usage scenarios of high/low temperature circulation environment.In addition, can the component parameter of MIFI systems be stablized also in high and low temperature environment
Unknown number, such as work in high and low temperature environment because component parameter change will cause MIFI system performances change and under
The possibility of drop, or even influence the service life of component.Therefore, it is not comprehensive, endless to there is detection covering in existing detection technique
The problem of whole, so as to cause to evade or hide the risk hidden danger of MIFI system security features.
(3) detection method of existing MIFI systems, the system reboot often fed back for user terminal, system configuration parameter are lost
Lose, the partial function of web page can not be enabled and disabled, system can not the abnormal problem such as factory reset, can not be preferable
Ground detects.
(4) MIFI systems are suitable for the supply district that alternating voltage is 100-240VAC~50/60Hz, but existing MIFI
System detecting method does not cover the detection of various electric source modes, for example, being not covered with AC power break-make electro-detection, straight
Galvanic electricity source break-make electro-detection, the detection of DC power supply hit, reset key restart detection, power button switch machine testing.MIFI systems
System such as runs into that alternating voltage is higher or relatively low when run its all properties, and the complete machine for being likely to influence MIFI systems is electric
, such as there is unstable voltage in gas performance failure and the phenomenon of decline, MIFI systems can be given to produce mortal injury or malfunction, shadow
Ring user to use, cause the return of goods to reprocess, many-sided loss such as quality is unstable.The aging of acceleration equipment at the same time, influence to use the longevity
Life even burns accessory, make user face the puzzlement that needs repairing or in a short time will more new equipment, waste of resource；Severe patient is very
To security incident occurs, immeasurable loss is caused.Therefore there are electric property for the existing detection method of current MIFI systems
Detect that covering surface is complete, incomplete state, it is impossible to preferably examine and confirm system be used in various different alternating voltages,
, it is hidden to there is the monitoring omitted to the reliability of electric property, security, stability in the electric property under various different electrical power frequencies
Suffer from.As MIFI systems because electric property is bad and caused by burning machine, power on and off, configuration loss, system reboot, crash, all can be tight
Normal use and the personal safety of user terminal are influenced again.In addition, bad defect can also cause great economy to manufacturing enterprise
Lose and produce undesirable public praise.
