Embodiment
In order to further specify principle of the present invention and structure, existing in conjunction with the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
The circuit structure block diagram of power equipment of the present invention as shown in Figure 1, comprising:
GSM/GPRS module 5 provides data exchange interface based on gsm system for power equipment.
RS485 module 7 provides communication interface based on 485 agreements for power equipment.
RS232 module 8 provides communication interface based on the RS232 agreement for power equipment.
Operation principle of the present invention is: at the inner temperature control modules 2 that adds of power equipment; be used for monitoring equipment internal cavity temperature or main euthermic chip temperature; design temperature protection threshold value in temperature control modules 2; when detected temperatures reached setting threshold, master chip 1 can select to reduce the partial function (except temperature control modules 2 functions) of operating frequency, closing device software systems or hardware system.When the equipment heating minimizing, after temperature reduced, temperature control modules 2 detected temperatures were lower than the temperature protection threshold value, and this moment, temperature control modules 2 can notify master chip 1 to improve all or part of function of operating frequency, starting device software or hardware system.Meanwhile, the good Heat Conduction Material (such as steel structure spare) of equipment choosing connects euthermic chip and device housings, and heat is directly exported to device housings, utilizes the big area of dissipation of device housings and equipment external environment directly to carry out heat exchange.Thereby equipment can be without fan and sealing fully.
At present embodiment, temperature control modules 2 adopts temperature sensor and microprocessor to realize.Can preserve a plurality of preset threshold value in the microprocessor, microprocessor is analyzed the temperature value that records by temperature sensor and is judged, regulates the power consumption of whole power equipment to send the multiple master chip 1 that outputs signal to for it.
In the running of this power equipment, temperature control modules 2 is in running order all the time, and other modules may be in running status, also may be in closed condition.
When temperature control modules 2 detections find that the temperature of master chip 1 is higher than the temperature protection threshold value, 1 frequency reducing of notice master chip.After 1 frequency reducing a period of time, when temperature control modules 2 is judged detected temperatures greater than (temperature protection threshold value P-temperature range of decrease amplitude Δ Q), notify master chip 1 shuts functional module: GSM/GPRS module 5 at master chip; PLC module 6, WiFi module 4, LAN module 3; RS485 module 7, RS232 module 8.In this embodiment, master chip 1 is to close PLC module 6, WiFi module 4, RS485 module 7 and RS232 module 8 simultaneously, and GSM/GPRS module 5 is restarted the function of system and the calling function of network of LAN module 3 is not closed.
After device temperature reduces, when temperature control modules 2 is judged detected temperatures greater than the cold-starting temperature, temperature control modules 2 notice master chips 1 recovery system.In this embodiment, temperature control modules 2 sends reset signal to master chip 1, and all functions module restarts.
If because certain cause, it is low excessively that the cold-starting temperature threshold is provided with, and when causing the functional module function to recover, can start functional module by other mode.In this embodiment, reset signal that can be by GSM/GPRS module 5 and restart whole system based on the WOL packet of LAN module 3.
Need to prove; can satisfy the functions of the equipments needs under the various different situations by the functional module that increases or reduce power equipment, also can change existing each functional module organizational form and realize the mechanism of functions of the equipments and self-protection more flexibly.
Compared with prior art, adopt power equipment of the present invention, possess intelligent temperature control, but long-time running is in characteristics such as unattended adverse circumstances, dustproof, waterproof, high life.

High temperature protection threshold value P: the temperature upper limit of equipment operation.When the detected temperatures of temperature control modules 2 reaches this value, can notify master chip 1 to take the high temperature protection measure.
Temperature range of decrease amplitude Δ Q: after referring to that master chip 1 is taked the frequency reducing measure, the minimum value of temperature fall.Reach this value if temperature descends, show that master chip 1 frequency reducing reaches the expection cooling-down effect, otherwise master chip 1 must be taked further cooling measure.
Cold-starting threshold value S: master chip 1 is adopted various measures when reducing device temperature, has also influenced all multi-functional of equipment.When the device temperature reduction reached cold-starting threshold value S, master chip 1 can the recovery system function.
Concrete steps are as follows:
S1: the software systems by equipment are provided with high temperature protection threshold value P to temperature control modules 2, and temperature range of decrease amplitude Δ Q is set, and cold-starting threshold value S is set.
S2: temperature control modules 2 detects master chip 1 temperature Q
S3: temperature control modules 2 judges detected temperatures Q whether greater than temperature protection threshold value P, judges promptly whether Q＞P sets up, if set up, jumps to S4, otherwise returns S2
S4: temperature control modules 2 notice master chips 1 reduce operating frequency
S5: master chip 1 low frequency operation, temperature control modules 2 continues to detect master chip 1 temperature Q
S6: after master chip 1 is reducing operating frequency work certain hour, temperature control modules 2 judges that whether detected temperatures Q is than the low Δ Q (temperature amplitude) of temperature protection threshold value P, judge promptly whether Q＜P-Δ Q sets up, reach the cooling Expected Results, return S5 if set up 1 frequency reducing of explanation master chip; If be false, illustrate that master chip 1 frequency reducing does not reach the Expected Results of cooling, jumps to S7.
S7: temperature control modules 2 notice master chips 1 are closed all or part of systemic-function
S8: temperature control modules 2 continues to detect master chip 1 temperature Q, and master chip 1 heating significantly reduces;
S9: temperature control modules 2 judges whether detected temperatures is lower than cold-starting threshold value S, judges promptly whether Q＞S sets up, if set up, changes S10, otherwise changes S8
S10: temperature control modules 2 sends hardware reset signal to master chip 1, restarts whole system, changes S2 after the system start-up.
More than this only is a preferable possible embodiments of the present invention, and unrestricted protection scope of the present invention so the equivalent structure that all utilizations specification of the present invention and accompanying drawing content have been done changes, all is included in protection scope of the present invention.Such as:
Can add or reduce parameter to temperature control modules 2, to adapt to more flexible and changeable device temperature control needs.Wait for that such as in temperature control modules 2, adding " frequency reducing stand-by period " master chip 1 frequency reducing cooling finishes, " multistage temperature range of decrease amplitude " is set comes opening and closing of each functional module of corresponding device or the like.
During the state of master chip 1 before the restorer high temperature protection, can be first recovery system function, also can be to improve operating frequency or both combining form earlier.During the recovery system function, can be all systemic-functions of disposable recovery, also can be to recover each functional module function one by one.
