Below in conjunction with accompanying drawing, describe embodiments of the invention in detail.
Method embodiment
A kind of control method of computer room temperature is provided in the present embodiment.
As shown in Figure 1, the control method according to the computer room temperature of present embodiment comprises:
Step S102 surpasses duration that machine room requires temperature in the temperature of machine room and improves the refrigeration of machine room under greater than the situation of very first time section, that is to say that the temperature of machine room must not surpass machine room for a long time and require temperature;
Step S104, the duration that is lower than minimum temperature threshold in the temperature of machine room surpassed for second time period (wherein, the length of the very first time section and second time period can be identical, also can be different, for example, the very first time section and second time period such as can be set to 1 minute, 2 minutes, 5 minutes at numerical value) situation under, reduce the refrigeration of machine room, wherein, minimum temperature threshold should require temperature less than machine room.
Although the order of carrying out above-mentioned steps has been shown among Fig. 1,, in actual applications, according to the difference of actual conditions, concrete execution sequence can change.
Particularly; the mode that changes the refrigeration of machine room has a lot; for example; usually machine room all is equipped with fan (or fan group) and air-conditioning; perhaps also can be equipped with the refrigeration plant with scavenger fan and air-conditioning integrated setting, therefore, the fan of hereinafter mentioning both can be arranged separately in the machine room; also can with the air-conditioning equipment integrated setting, and the rotating speed of fan can have a plurality of gears.

When outdoor temperature is lower than outdoor design temperature and passes through to open the refrigeration of fan raising machine room, determine the initial speed of fan according to the Current Temperatures difference of outdoor temperature and machine room, and the initial speed unlatching fan to determine, specifically how to select initial speed to be described in more detail below.
In addition, be higher than under the situation of maximum temperature threshold value, adopt the best refrigeration modes of refrigeration that machine room is freezed in the temperature of machine room.Be higher than under the situation of duration greater than the 3rd time period of machine room requirement temperature and work as computer room temperature, can alarm, wherein, the length of the 3rd time period should be greater than the above-mentioned very first time section and second time period.
By above-mentioned processing, can in the desired computer room temperature of the normal operation of assurance equipment, reduce the use of air-conditioning as far as possible, and allow fan work at less rotating speed gear even make air-conditioning and fan all cuts out as far as possible, thereby reach purpose of energy saving.
The present invention considers as characteristics such as the high-performance of the base station of communications equipment room nucleus equipment, high stability, high robusts, make the base station on the basis of the communication function of bearing self, subsidiary functions such as further realization environmental monitoring (for example, monitoring and control to cigarette, dirt, temperature, humidity), reach administrative purposes to the machine room refrigeration plant.In addition, the base station also can connect webmaster (for example, the Node B (Evolved Node B abbreviates eNB as) of evolution is connected to network management system (O﹠amp in the long evolving system (Long TermEvolution abbreviates LTE as); M)) or by base station controller connect webmaster (as global system for mobile communications (Global System for Mobile Communications, abbreviate GSM as) in base transceiver station (Base Transceiver Station, abbreviate BTS as) be connected to O﹠amp by base station controller (Base StationController abbreviates BSC as); M, and the Node B in the universal mobile telecommunications system (Universal MobileTelecommunications System abbreviates UMTS as) arrives O﹠amp by radio network controller (Radio Network Controller abbreviates RNC as); M), environmental parameter etc. just can be reported to webmaster in the base station like this, and webmaster just can indicate the base station to carry out suitable action or notice manual intervention in view of the above.
The present invention can carry out the detection of computer room temperature and outdoor temperature by the base station by means of the high handling property of base station, and by base stations control fan and air-conditioning; Also can detect machine room and outdoor temperature by the base station, and the temperature that detects reported webmaster, judge refrigeration how to adjust machine room by webmaster, and the order that will improve/reduce rotation speed of the fan, On/Off fan, On/Off air-conditioning sends to the base station, by the base station fill order, adjust refrigeration.

Time period T2 (corresponding to above-mentioned very first time section), T2 be less than T1, when the duration that computer room temperature is higher than machine room requirement temperature surpasses T2, improves rotation speed of the fan.
Outdoor design temperature, this temperature are lower than above-mentioned machine room and require temperature.
Indoor design temperature 1 (corresponding to above-mentioned maximum temperature threshold value), this temperature is higher than above-mentioned machine room and requires temperature.
Indoor design temperature 2 (corresponding to above-mentioned minimum temperature threshold): this temperature is lower than above-mentioned machine room and requires temperature.
Time period T3 (corresponding to above-mentioned second time period): when computer room temperature is lower than above-mentioned indoor design temperature 2 above this time period, reduce rotation speed of the fan etc.
To the control method according to computer room temperature of the present invention be described based on above setting below.
As shown in Figure 4, suppose that the initial refrigerating state of machine room is the air conditioner surroundings refrigeration, under air conditioner surroundings, when outdoor temperature was lower than outdoor design temperature, control command was sent in the base station, open air inlet, start fan (wherein, the initial gear of rotation speed of the fan can be set) and introduce outdoor Cryogenic air, discharge indoor high temperature air according to the difference of outdoor temperature and machine room indoor temperature, to reach cooling-down effect, close air-conditioning;
Under the fan environment, when computer room temperature was higher than the duration overtime section T2 of machine room requirement temperature, control command was sent in the base station, improved rotation speed of the fan;
Under the fan environment, when rotation speed of the fan reaches maximum gear, the situation that computer room temperature is higher than the duration overtime section T2 of machine room requirement temperature still occurs, then control command is sent in the base station, starts air-conditioning, closes fan, closes air inlet;
Under the fan environment, when computer room temperature was higher than indoor design temperature 1, then control command was sent in the base station, started air-conditioning, closed fan, closed air inlet;
Under the fan environment, when computer room temperature was lower than the duration overtime section T3 of indoor design temperature 2, then control command was sent in the base station, reduced rotation speed of the fan;
Under the fan environment, when rotation speed of the fan reaches minimum gear, the situation that computer room temperature is lower than the duration overtime section T3 of indoor design temperature 2 still appears, and then the base station can be sent control command and be closed fan, also can not send any control command (that is, making fan) still with minimum gear operation.As closed fan, when computer room temperature reached machine room requirement temperature, then the base station should be sent control command and restarted fan (rotation speed of the fan just begin to be made as in the middle of gear).
Under any circumstance, when computer room temperature was higher than machine room requirement temperature overtime section T1, alarm signal can be sent in the base station, and reports O﹠amp; M.
Alternatively, as shown in Figure 2, the base station also can report O﹠amp to the control command information that fan/air-conditioning sends; M, the information that reports can comprise time of controlling the base station, action etc., so that O﹠amp; M adds up, analyzes, and then optimizes above-mentioned configuration parameter etc.
Example 2

Similarly, in this example, need O﹠amp; M this locality is configured to down parameter:
Machine room requires temperature, time period T2 (corresponding to above-mentioned very first time section), outdoor design temperature (this temperature is lower than above-mentioned machine room and requires temperature), indoor design temperature 1 (corresponding to above-mentioned maximum temperature threshold value), indoor design temperature 2 (corresponding to above-mentioned minimum temperature threshold), time period T3 (corresponding to above-mentioned second time period), identical in the implication of concrete each parameter and the example 1, no longer repetition here.
In the temperature controlled processes of this example, as shown in Figure 4, suppose that machine room is initially air conditioner surroundings, the present embodiment course of work is as follows:
The base station reports O﹠amp with computer room temperature and outdoor temperature data in real time; M;
Under the air conditioner surroundings, when outdoor temperature is lower than outdoor design temperature, O﹠amp; M sends control command, and by the base station, opens air inlet, starts fan (rotation speed of the fan just begins to be made as middle gear) and introduces outdoor Cryogenic air, discharges indoor high temperature air, to reach cooling-down effect, closes air-conditioning;
Under the fan environment, when computer room temperature is higher than machine room requirement temperature above setting-up time 2, O﹠amp; M sends control command, and by the base station, improves rotation speed of the fan;
Under the fan environment, when rotation speed of the fan reaches maximum gear, computer room temperature still occurs and be higher than the situation that machine room requirement temperature surpasses setting-up time 2, then O﹠amp; M sends control command, and by the base station, starts air-conditioning, closes fan, closes air inlet;
Under the fan environment, when computer room temperature is higher than indoor design temperature 1, O﹠amp then; M sends control command, and by the base station, starts air-conditioning, closes fan, closes air inlet;
Under the fan environment, when computer room temperature is lower than indoor design temperature 2 and surpasses setting-up time 3, O﹠amp then; M sends control command, and by the base station, reduces rotation speed of the fan;
Under the fan environment, when rotation speed of the fan reaches minimum gear, computer room temperature still occurs and be lower than the situation that indoor design temperature 2 surpasses setting-up time 3, then O﹠amp; M can send control command, and closes fan by the base station, also can not send any control command (being that fan is still with minimum gear operation).As closed fan, and when computer room temperature reaches machine room requirement temperature, O﹠amp then; M should send control command, and restarts fan (rotation speed of the fan just begins to be made as middle gear) by the base station;
In any case, when computer room temperature is higher than machine room requirement temperature and surpasses setting-up time 1, O﹠amp then; M sends alarm signal.
Particularly, in said method and example, the selection of fan initial speed (selecting the initial gear of fan), can be undertaken by following processing:
When computer room temperature was higher than machine room requirement temperature, the initial gear of rotation speed of the fan was selected maximum gear for use.
When computer room temperature was lower than indoor design temperature 2, the initial gear of rotation speed of the fan was selected minimum gear for use.
When computer room temperature is between machine room requirement temperature and indoor design temperature 2, gear in the middle of the initial gear of rotation speed of the fan can be selected for use, or determine the selection of the initial gear of rotation speed of the fan according to the difference of outdoor temperature and machine room indoor temperature at that time, the more little then initial gear of temperature difference should be big more, and the big more then initial gear of temperature difference can be more little.For example, suppose that fan has 5 shelves, 1 grade is the rotating speed maximum, and 5 grades is the minimum shelves of rotating speed, at this moment, can obtain the initial gear of rotation speed of the fan by question blank 1, and the content shown in the table 1 can be at O﹠amp; M is configured, and also can be used as configuration parameter by O﹠amp; M is configured to the base station.
