Description
Technical Field
The invention relates to the technical field of temperature control of a base station room, in particular to a temperature control method and a temperature control system of the base station room.
Background
The power supply equipment, the transmitting equipment, the transmission equipment and the like in the base station room are all large heating elements, the heat energy generated in the operation process of various equipment is accumulated in the base station, the equipment in the base station room usually has a normal working temperature range, for example, the design specification of the electronic information system room GB 50174-2017-appendix a, which specifies the temperature range of each area in the base station, specifically, the ambient temperature and relative humidity (at shutdown) of the main room are 5 to 45 ℃ and 8 to 80%, the temperature and relative humidity of the air intake area of the cold aisle or cabinet are required to be 18 to 27 ℃ and not more than 60%, the temperature and relative humidity (at startup) of the auxiliary area are required to be 18 to 28 ℃ and 35 to 75%, the temperature and relative humidity (at shutdown) of the auxiliary area are required to be 5 to 35 ℃ and 20 to 80%, and the temperature of the battery room of the uninterruptible power supply system is required to be 20 to 30 ℃. Therefore, in order to maintain the normal operation of the equipment, the temperature of the working environment in the room must be kept within a reasonable range, and therefore, the temperature in the room of the base station room needs to be lowered by the refrigeration equipment.
In order to control the temperature, it is a common practice to equip the base station with air conditioners, which not only consume much power, but also are vulnerable to damage, often require maintenance and replacement, and have high operation cost. However, the outdoor temperature is also greatly different due to the difference of natural environment and geographical location, and the indoor temperature can be controlled by only relying on the natural air heat exchange with the outside in many cases. Therefore, many researchers develop a scheme for regulating and controlling the indoor temperature of the base station machine room by the fresh air system and the air conditioner together.
For example, patent application document CN 206522907U discloses an energy-conserving temperature control system of base station intelligence new trend, and the theory of operation is: the working time periods of the base station air conditioner and the intelligent fan system can be freely set according to seasons and outdoor temperature conditions through a keyboard and a mouse in the peripheral input device, the opening time periods and the closing time periods of the base station air conditioner and the fresh air system are input and preset, and then the time periods of the base station air conditioner and the fresh air system can be controlled through the cooperation of the central controller and the clock module, so that the problem of disturbance of residents caused by excessive noise at night of the outdoor unit of the base station air conditioner is solved. However, the temperature control system presets the starting time periods of the air conditioner and the fresh air system according to the previous temperature change conditions, and the weather change cannot be controlled, so that the mode is not accurate enough, and the indoor temperature of the base station room cannot be guaranteed to be always in a proper range.
And patent application document CN 207584977U discloses a base station energy-saving temperature control system, the work flow is: when the indoor temperature is lower than 28 ℃ and the outdoor temperature is lower than the indoor temperature, the air conditioner is turned off, the fresh air system is started to dissipate heat, when the fan reaches the maximum rotating speed and the indoor temperature still exceeds 28 ℃, the central control module 31 sends a command to turn off the fresh air system and turn on the air conditioner 2 through the infrared emitter 35, and the maximum-efficiency heat dissipation is performed through the air conditioner, of course, when the outdoor temperature is higher than the indoor temperature, the fresh air system is always turned off to dissipate heat only through the air conditioner (the national standard GB50174-93 stipulates that the temperature of a base station allowing the equipment to operate for a long time should be controlled to be 18-28 ℃).
In the base station energy-saving temperature control system disclosed in the above patent application document CN 207584977U, the highest temperature threshold of the base station room specified by the national standard is used as the preset indoor highest temperature threshold, but the air conditioner generally needs to operate the compressor for 2-3 minutes to start cooling, and the indoor temperature still rises during the period, so the response is not sensitive enough; in addition, when the indoor temperature exceeds the maximum temperature threshold of 28 ℃ and the outdoor temperature is lower than the indoor temperature, fresh air is firstly adopted for cooling, and an air conditioner is used for refrigerating under the condition that the maximum power of a fresh air system is not achieved, and the problem that the regulation time is delayed due to the fact that the fresh air is firstly cooled and then the refrigerating is cooled under the condition that the outdoor temperature is higher than the maximum temperature threshold of 28 ℃ or is less than or equal to the maximum temperature threshold of 28 ℃ because different regulation modes are adopted under the two conditions that the outdoor temperature is higher than the maximum temperature threshold of 28 ℃ at the moment is not discussed respectively, the indoor temperature still rises during the period, and the classification method of the cooling condition is not accurate enough; moreover, it is not considered how to adjust the temperature control when the indoor temperature is lower than the minimum temperature threshold; in addition, the influence of outdoor relative humidity on indoor humidity when fresh air is used for cooling is not considered, if the outdoor relative humidity is high, the indoor humidity can be changed quickly after ventilation, and a dehumidifying device may not be in time to reduce the humidity, so that the good operation of base station equipment can be influenced in the period.
Therefore, the temperature control method and the temperature control system of the base station room in the prior art have further room for improvement.

On the basis of the embodiment 1, the invention specifies the preset highest temperature threshold value ThAnd presetting a minimum temperature threshold TcMaximum temperature threshold T of base station room specified by national standardGauge hAnd the highest relative humidity threshold RH of the base station room specified by the national standardGauge hThe method of (1). The specific situation is as follows:
further, considering that the air conditioner 3 is not started to immediately cool down, in view of time delay, in order to keep enough time for temperature adjustment, the maximum temperature threshold T is preset in this embodimenthThe highest temperature threshold T of the base station room is specified by the national standardGauge h1-2 ℃ lower, ensuring that the indoor temperature T is ensured in the time delay periodInner partThe temperature of the continuous rising of the temperature does not exceed the highest temperature threshold T of the base station room specified by the national standard within a certain rangeGauge h。
And national standards such as electronic information system machine room design specifications GB 50174-2017-annex a, it can be understood that if there are other latest policies, execution is performed according to the latest standards. Of course, more stringent industry standards or regional standards may be employed without violating national standards.
Further, the highest temperature threshold T of the base station room 1 specified by the national standardGauge hMinimum of the following maximum temperature thresholds specified for national standards: the temperature of the environment of the main computer room, the temperature of the auxiliary area, the temperature of a battery chamber of the uninterruptible power supply system and the temperature of an air inlet area of a cold channel or a cabinet. The minimum value among the maximum temperature thresholds fixed by the plurality of base station apparatuses 4 is adopted, so that the temperature control conditions of all the base station apparatuses 4 can be satisfied under the same temperature control condition.
Further, for similar reasons as described above, a minimum temperature threshold T is presetcThe minimum temperature threshold T of the base station machine room is specified by the national standardGauge cThe height is 1-2 ℃. Furthermore, the minimum temperature threshold T of the base station room 1 specified by the national standardGauge cMaximum of the following minimum temperature thresholds specified by national standards: the temperature of the environment of the main computer room, the temperature of the auxiliary area, the temperature of a battery chamber of the uninterruptible power supply system and the temperature of an air inlet area of a cold channel or a cabinet.
Further, the highest relative humidity threshold RH of the base station room 1 specified by the national standardGauge hMinimum of the following maximum relative humidity thresholds specified by national standards: the relative humidity of the environment of the main computer room, the relative humidity of the auxiliary area and the relative humidity of the air inlet area of the cold channel or the cabinet.
For example, in the design specification GB 50174-2017-appendix a of the electronic information system room, the ambient temperature and relative humidity (at shutdown) of the main room are 5 to 45 ℃ and 8 to 80%, the temperature and relative humidity of the air intake area of the cold aisle or cabinet are required to be 18 to 27 ℃ and not more than 60%, the temperature and relative humidity (at startup) of the auxiliary area are required to be 18 to 28 ℃ and 35 to 75%, the temperature and relative humidity (at shutdown) of the auxiliary area are required to be 5 to 35 ℃ and 20 to 80%, and the temperature of the battery compartment of the uninterruptible power supply system is required to be 20 to 30 ℃. Therefore, after comprehensive consideration, the highest temperature threshold T of the base station room 1 specified by the national standardGauge hIs 27 ℃, and the minimum temperature threshold T of the base station room 1 specified by the national standardGauge cIs 20 ℃, and the highest relative humidity threshold RH of a base station room 1 specified by the national standardGauge hThe content was 60%. Therefore, in this embodiment, the base station room 1 is provided withSetting a maximum temperature threshold ThCan be set to 26 ℃, and the minimum temperature threshold value T is presetcIt can be set to 21 ℃.
At TOuter cover(30℃)≥Th(26℃)，TInner part(33 ℃ C. or 28 ℃ C.)>Th(26 ℃ C.), regardless of TOuter coverAnd TInner partThe air conditioner 3 is required to start the cooling mode to the indoor temperature TInner partTo reach Tc～(Tc+Th) The air conditioner 3 is closed;

Based on embodiment 1, the present embodiment deals with the indoor temperature TInner partOutdoor temperature TOuter coverOutdoor relative humidity RHOuter coverA detailed description will be given.
Further, the indoor temperature TInner partThe maximum value among the indoor temperature values collected by the indoor temperature sensors 5 arranged for the plurality of monitoring points. In this embodiment, a plurality of rooms may be provided in the base station room 1The inner temperature sensors 5 are uniformly arranged around the base station equipment 4, so that the indoor temperature T acquired by the indoor temperature sensors 5 is ensuredInner partMore accurately, the local temperature rise caused by equipment heating is avoided, but the detection is not timely due to the fact that the single indoor temperature sensor 5 is arranged at a position far away from the local temperature rise region, and therefore the temperature control method is not sensitive. Indoor temperature sensor 5 is arranged to the multiple spot, reaches sensitive temperature data acquisition, and then realizes the accurate control to the temperature to guarantee the normal operating of basic station equipment 4.
The outdoor temperature sensor 6 may have only one or more outdoor temperature TOuter coverIs the average value of the outdoor temperature values collected by the plurality of outdoor temperature sensors 6.
And the outdoor relative humidity sensor 7 can have only one or more outdoor relative humidity RHOuter coverIs the average of the outdoor relative humidity values collected by the plurality of outdoor relative humidity sensors 7.
Example 4
On the basis of the embodiment 1, the fresh air system 2 and the air conditioner 3 are considered to be damaged after long-term operation, so that the temperature control function is disabled, and therefore, the embodiment optimizes the temperature control function.
In this embodiment, after the fresh air system 2 is turned on, the indoor temperature T is within the preset timeInner partIf the fresh air system 2 is not reduced, the fresh air system is judged to be invalid, the air conditioner 3 is started, and meanwhile, the remote monitoring center 8 is informed;
after the air conditioner 3 starts the heating mode, the indoor temperature T is within the preset timeInner partIf the temperature is not increased, the heating mode of the air conditioner 3 is judged to be invalid, and meanwhile, the remote monitoring center 8 is informed;
after the air conditioner 3 starts the refrigeration mode, the indoor temperature T is within the preset timeInner partIf the temperature is not lowered, the refrigeration mode of the air conditioner 3 is judged to be invalid, and the remote monitoring center 8 is notified.
The preset time can be 5-10min, if the preset time is more than 10min, the purpose of quickly finding out the temperature control failure of the fresh air system 2 and the air conditioner 3 cannot be achieved, and the operating condition of the base station equipment 4 can be influenced due to the fact that the temperature in the base station machine room 1 continuously rises; if the preset time is less than 5min, erroneous judgment may be caused, for example, the air conditioner 3 sold in the market at present basically starts to operate after the compressor is started for 2-3min, so that temperature change may not be detected within 3min, and if the preset time is less than 5min, it cannot be accurately judged whether the air conditioner 3 is damaged to cause failure or the air conditioner 3 normally operates but takes effect slowly. Preferably, the preset time may be 5-7 min.
