Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution 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, is not whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
In order to further reduce the cost that electronic product prevents disassembling running technology, in the embodiment of the present invention, electronics production is obtained
The temperature of preset each test point in product, and be according to preset each test point in electronic product and do not disassemble operating status
Under temperature, judge whether the temperature of each test point abnormal, determine electronic product whether in disassembling operating status, and then adopt
The electronic product is protected with preset safeguard procedures, needs not rely upon the connection of any external physical, it is special hard without increasing
Part designs, and reduces cost.
The present invention program is described in detail below by specific embodiment, certainly, the present invention is not limited to following realities
Apply example.
What deserves to be explained is in practice, the anti-operation method of disassembling of electronic product is generally required dependent on extraneous physics company
It connects or hardware circuit that itself is special, increases cost, without additionally increasing cost, calculated based on software in present example
Method is in disassembling operating status, and then realize the guarantor to electronic product to judge electronic product in operating status is not disassembled
Shield, therefore, the electronic product in the embodiment of the present invention need to have following basic condition：
1) software control is included, pure hardware is not suitable for.
2) electronic product has apparent casing, air-cooled naturally cold unlimited.
3) temperature at element or inner space position in environment temperature and machine is needed to refer to when electronic product is run to be transported
Row management.
As shown in fig.1, in the embodiment of the present invention, electronic product prevents disassembling that the idiographic flow of the method for operation is as follows：
Step 100：When determining that electronic product is in operating status, preset each test point in the electronic product is detected
Temperature.
In practice, electronic product is not in the case where disassembling operating condition, in environment temperature (for example, being set as A points) and electronic product
Mapping relations between the temperature of each element or each space position (for example, wherein any one is set as B points) must be
Know, for example, when A points are 25 degree, the temperature range of B points is 30 degree~90 degree, that is to say, that be 25 in A points during stable operation
When spending, the value one of the temperature of B points is scheduled between 30 degree~90 degree, for example, the temperature for detecting B points is 50 degree, then in electronics
When all constant, the temperature of B points will not change for the service condition of product, workload.And when electronic product is disassembled
When, i.e. the casing of electronic product is run after being opened, then the radiating condition of the electronic product will significantly change, for example, A points
At 25 degree, the temperature range of B points is likely to that 30 degree~70 degree will be become, i.e. the temperature of B points will change, exact, for
Each determining operating status, B point temperature can completely change in casing with when casing removal, for example, when having casing, B
Point temperature is known 50 degree, removes casing, and B points temperature becomes for 60 degree.I.e. under determining operating status, B point temperature
No longer it is known 50 degree.
In this way, in the embodiment of the present invention, it is possible to according to the temperature of currently detected B points and the positive room temperature of the B points of record
Whether degree is consistent, so as to judge that electronic product whether in operating status is disassembled, can further take corresponding safeguard procedures.
Wherein, above-mentioned preset each test point, can temperature measuring point or use of the electronic product when running in itself
The temperature measuring point that family increases newly according to demand in the embodiment of the present invention, is not defined, improves the flexibility of thermometric.
Also, the number of preset each test point,, can be according to reality also without limiting in the embodiment of the present invention
Situation is set, and can be one, or and it is multiple, preferably, disassembling shape to further improve follow-up determine whether
The accuracy of state, using the existing test point of multiple electronic products itself, for example, using 4 test points, respectively A points, B points,
C points, D points.
This is because if in case of a fault, electronic product has been not normally functioning, whether no matter opening shell, it is then
It is no to be disassembled, it is likely that the temperature of B points does not change at this time, but as long as still there is the C points of partial duty in electronic product, then examines
Measuring the temperature of C points can also have any different, it is possible to be judged according to the temperature change of C points, therefore, set multiple detections
Point can improve judgement precision.
Certainly, if whole circuits do not work in electronic product, electronic product also need not just be protected, this
In the case of can not consider in the embodiment of the present invention.
Step 110：Respectively according to the normal temperature of preset each test point, the temperature of each test point is judged
Whether degree is abnormal；Wherein, the normal temperature is to be in temperature when not disassembling operating status in the electronic product.
When performing step 110, specifically include：
First, the normal temperature of above-mentioned each test point is determined respectively.
Wherein, the normal temperature of above-mentioned preset each test point is to be in not disassemble operating status according to electronic product
When the temperature set that obtains determine.
Wherein, the acquisition pattern of above-mentioned temperature set, can there is following two modes：
First way：Pass through actually detected acquisition.
That is, in the embodiment of the present invention, it can be when the casing of electronic product not be dismantled, by actually detected, directly
It obtains under the determining operating status of a certain kind, the normal temperature of each test point.
For example, as shown in fig.2, A1, A2 ..., An is different environment temperature, such as respectively 25 degree, and -40 spend ...
45 degree, B1, B2 ..., the B3 value ranges for the normal temperature of B points at different ambient temperatures.
In the embodiment of the present invention, the normal temperature of each test point can be obtained, and preserve acquisition beforehand through actually detected
B points normal temperature at different ambient temperatures, for example, under a certain determining operating status, B1 is 40 when A1 is 25 degree
Degree, when A2 is spent for -40, B2 is 10 degree etc., if in this way, when to get current environment temperature be 25 degree, it is possible to directly determining B
The normal temperature of point is 40 degree.
The second way：Acquisition is calculated according to preset operating parameter and preset operation mode.
Wherein, the operating parameter is following any one or arbitrary combination：Environment temperature, loading condition, input condition.
Certainly, in the embodiment of the present invention, it is not limited in above-mentioned several operating parameters, can be selected according to actual conditions
It selects and sets.
For example, the mapping pass that operating parameter is environment temperature, operation mode is environment temperature and the normal temperature of test point
System, then, specially：According to the current environment temperature and preset environment temperature detected and the positive room temperature of each test point
What the mapping relations of degree obtained.
According to above-mentioned first way it is found that the data in this temperature set by actually detected acquisition preserved are got over
It is more, it is possible to more accurately determine the normal temperature of each test point, but institute's data to be saved will be very much, in practice,
General disassemble usually all carries out indoors, therefore, need to only preserve the normal temperature of corresponding B points when A points are 5~30 degree i.e.
It can.But in this case, the data of preservation cannot include the value condition of all A, accordingly it is also possible to according to having protected certainly
The data deposited, statistics obtain its changing rule, obtain the mapping relations of environment temperature and the normal temperature of test point, and then according to
The mapping relations extrapolate the normal temperature of B points at different ambient temperatures.
In another example the mapping for the normal temperature that operating parameter is loading condition, operation mode is loading condition and test point
Relationship, then, specially：According to the mapping of the current loading condition and preset loading condition detected and each test point
What relationship obtained.
That is, electronic product can also be preserved in different loads, and the normal temperature of each test point, example
When such as, for semi-load, the normal temperature of each test point；For full load, the normal temperature of each test point, and then according to determining
The mapping relations of loading condition and test point, to extrapolate the normal temperature of test point.
Then, judge whether the temperature of above-mentioned each test point is abnormal, specially：
The temperature of the above-mentioned each test point detected and the normal temperature of above-mentioned each test point are compared respectively,
And when determining the temperature of any one the and/or multiple test points detected and above-mentioned any one and/or multiple test points
When normal temperature differs, the temperature anomaly of above-mentioned any one and/or multiple test points is determined.
What deserves to be explained is the normal temperature and the temperature of currently detected test point that are compared, it should be except
It is obtained under the same conditions except the condition whether electronic equipment is disassembled, to prevent from judging by accident.
Further, the variation of the temperature of each test point can be detected and sentenced by the software of electronic product itself
It is disconnected, it can also be judged by the way that the data of the temperature of each test point are reported to monitoring by monitoring.
Step 120：When determining that the situation of the temperature anomaly of each test point meets preset protection condition, institute is judged
It states electronic product and is in and disassemble operating status, and the electronic product is protected using preset safeguard procedures.
When performing step 120, specifically include：
First, when determining that the situation of the temperature anomaly of above-mentioned each test point meets preset protection condition, judgement is above-mentioned
Electronic product is in and disassembles operating status, is specifically divided into following several situations：
The first situation：If only there are one test points, it is determined that during the temperature anomaly of said one test point, judgement is above-mentioned
Electronic product is in and disassembles operating status.
The second situation：When the number of the test point of temperature exception reaches the first predetermined threshold value, above-mentioned electronics is judged
Product is in and disassembles operating status.
The third situation：The number of the test point of temperature exception reaches the second predetermined threshold value, and the inspection of temperature anomaly
When the number that the number of measuring point reaches the second predetermined threshold value is not less than third predetermined threshold value, judges that above-mentioned electronic product is in and disassemble
Operating status.
For example, there is 4 test points, respectively A points, B points, C points, D points continuously have detected 8 times, and the second predetermined threshold value is 2,
Third predetermined threshold value is 5, then at the end of this 8 times are detected, if during at least 5 times detections, the test point of temperature anomaly has reached 2
It is a, then judge that electronic product is in and disassemble operating status.
Wherein, the first predetermined threshold value, the second predetermined threshold value, the value of third predetermined threshold value, in the embodiment of the present invention, not
It is defined, can be set according to actual demand, improve electronic product and prevent disassembling the intelligent and flexible of operation method
Property.
Then, above-mentioned electronic product is protected using preset safeguard procedures.
Wherein, above-mentioned preset safeguard procedures are following any one or combination：Self-locking shutdown protection (locks the electronics
Product), limitation electronic product service ability or function.
For example, if electronic product is in steady operational status, there are 4 test points, respectively A points, B points, C points, D points, often
It detects the temperature of one-time detection point at any time, continuously has detected 10 days, and the second predetermined threshold value is 3, third predetermined threshold value
It is 5, then in each detection, if the test point of temperature anomaly has reached 3, current detection is denoted as 1 time, if having remembered at least 5
It is secondary, then judge that electronic product is in and disassemble operating status, i.e., the electronic product is in and opens shell operating status, then is protected using self-locking
Shield locks the electronic product.
In another example if electronic product, which is in, frequently switches on machine state, there are 4 test points, respectively A points, B points, C points, D
Point is more than certain time, such as during half an hour in each be switched on, and detects the temperature of primary each test point, and continuous detect 5 times is opened
Machine, the second predetermined threshold value are 2, third predetermined threshold value 3, then in each detection, if the test point of temperature anomaly has reached 2
It is a, and in this 5 times detections, the number for having the test point of 2 temperature anomaly has reached 3 times, then judges that electronic product is in
Operating status is disassembled, i.e., the electronic product is in and opens shell operating status, then using self-lock protection, locks the electronic product.
Further description is made to above-described embodiment using a specific application scenarios below.Using electronic product as
