Embodiment
Core concept of the present invention is: obtain the temperature of electronic equipment, according to Critical Control temperature predetermined in the temperature of obtaining, the electronic equipment duty of the ventilation unit in the electronic equipment is carried out control and management.
Based on core concept of the present invention technical scheme provided by the invention is further described below.
When phenomenon on fire took place, if there is sufficient oxygen in place on fire, the intensity of a fire can sharply spread; In contrast, if fire and oxygen is isolated, the intensity of a fire can be very fast controlled.The present invention just is being based on this common, the most effective fire-fighting principle.
The cabinet of general electronic equipment all is enclosed, and electronic equipment all is provided with ventilation unit such as fan etc. for reason such as dispel the heat, and ventilation unit can make the cold air of electronic equipment chassis outside enter cabinet.When in the cabinet of electronic equipment phenomenon on fire taking place, ventilation unit has often played opposite effect, offers local sufficient oxygen on fire, makes The fire spreads quickly.Therefore, the present invention carries out control and management by the ventilation unit to electronic equipment, when phenomenon on fire takes place electronic equipment, makes ventilation unit can not realize its ventilation function, thereby breaks off the oxygen supply in the electronic equipment, and the intensity of a fire is effectively controlled.
Be that example is described in further detail method of the present invention below with the fan.
At first, Critical Control temperature predetermined in the electronic equipment is set.This Critical Control temperature is to judge whether electronic equipment the standard of phenomenon on fire takes place.
Then, obtain the temperature in the electronic equipment chassis in real time, Critical Control temperature predetermined in the temperature obtained and the electronic equipment is compared, if the temperature of obtaining does not surpass Critical Control temperature predetermined in the electronic equipment, proceed the comparison of said temperature, surpass Critical Control temperature predetermined in the electronic equipment until the temperature of obtaining; If the temperature of obtaining has surpassed the Critical Control temperature of being scheduled in the electronic equipment, determine that phenomenon on fire has taken place unusually, occurred electronic equipment, then cut off the power supply of fan, fan is quit work, the oxygen of breaking off in the electronic equipment is supplied with, the intensity of a fire can not spread under the situation of anoxic, even extinguish gradually.This is the ground floor control and management of the present invention to ventilation unit in the electronic equipment.
In the time can't normally carrying out above-mentioned comparison to temperature in the electronic equipment and Critical Control temperature, the present invention can also force the dump with fan, supplies with to realize the oxygen of breaking off in the electronic equipment.Specifically can adopt Thermal Cutoffs method such as connect with fan power supply is realized, when the temperature of electronic equipment surpasses the temperature that Thermal Cutoffs etc. can bear, the Thermal Cutoffs automatic cutout, the power supply of fan is cut off.This is the second layer control and management of the present invention to ventilation unit in the electronic equipment.
By this two-layer control and management to the ventilation unit in the electronic equipment provided by the invention, can guarantee that when phenomenon on fire takes place electronic equipment the oxygen of breaking off in the electronic equipment chassis is supplied with.
Be that example is described in further detail device of the present invention below with the fan.
The logic diagram of the management devices of ventilation unit as shown in Figure 2 in the electronic equipment of the present invention.
In Fig. 2, device provided by the invention comprises: Critical Control temperature memory module 200, temperature collect module 210, control and management module 220, high temperature catch-holder module 230.
Predetermined Critical Control temperature in the electronic equipment that Critical Control temperature memory module 200 receives and the storage user is provided with.
Temperature collect module 210 is gathered the temperature information in the electronic equipment in real time, and the temperature information of gathering is transferred to control and management module 220.
The function of temperature collect module 210 can adopt temperature sensor to realize in actual applications.Temperature collect module 210 comprises at least one temperature sensor, and is according to the actual conditions in the electronic equipment chassis, that the difference that a plurality of temperature sensors are arranged in the electronic equipment chassis is local.
The function of control and management module 220 is realized jointly by temperature judgement and controlling sub 221 and catch-holder module 222.
Temperature is judged and controlling sub 221 is obtained Critical Control temperature predetermined in the electronic equipment from Critical Control temperature memory module 200, receive the temperature information that temperature collect module 210 transmission come, temperature information and Critical Control temperature are compared, if temperature information does not surpass the Critical Control temperature, temperature judges that the temperature collect module 210 that continues to receive with controlling sub 221 transmits the temperature information and the Critical Control temperature of coming and compares, and surpasses the Critical Control temperature until temperature information.If temperature information surpasses the Critical Control temperature, temperature is judged with controlling sub 221 will open circuit command transfer to catch-holder module 222.
Catch-holder module 222 is connected with fan power supply, after receiving the order of opening circuit that temperature is judged and controlling sub 221 transmission come, with the dump of fan in the electronic equipment.
Catch-holder module 222 can adopt in actual applications and be subjected to temperature to judge the components and parts of controlling with controlling sub 221 such as switch.Catch-holder module 222 can be arranged on the following air port of electronic equipment ventiduct, also can be arranged on other suitable places according to the concrete space structure in the electronic equipment chassis.
The function that above-mentioned each module, submodule are realized is the ground floor control and management of the present invention to the electronic equipment ventilation unit.
Judge with controlling sub 221 etc. because break down when the reason cisco unity malfunction such as burning when the Critical Control temperature memory module 200 in the electronic equipment, temperature collect module 210, temperature, can cause catch-holder module 222 when phenomenon on fire takes place electronic equipment, can not cut off the power supply of fan.Safety for electronic equipment; the present invention connects high temperature catch-holder module 230 with fan power supply; and high temperature catch-holder module 230 is arranged on the following air port of electronic equipment ventiduct; like this; when phenomenon on fire takes place electronic equipment; and other modules of the present invention have been burnt; when catch-holder module 222 can not be cut off the power supply of fan; the temperature in air port can rise under the electronic equipment ventiduct; when temperature reached a high temperature the temperature that catch-holder module 230 can bear, high temperature catch-holder module 230 is fusing automatically, equally can be the dump of fan; reach the purpose of the control intensity of a fire, further protected electronic equipment.
The function that high temperature catch-holder module 230 realizes is the second layer control and management of the present invention to the electronic equipment ventilation unit.
High temperature catch-holder module 230 can adopt all components and parts that raise and can open circuit when temperature such as high temperature fuse, high temperature scolding tin, thermistor in actual applications.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wishes that appended claim comprises these distortion and variation.
