Summary of the invention
The invention provides a kind of method that improves base station and epitaxial device hot operation ability, when ambient temperature is too high, can shut down and the problem of interrupt communication to solve base station of the prior art.
For addressing the above problem, the invention provides following solution:
A kind of method that improves base station and epitaxial device hot operation ability, the concrete steps of this method are: when the ambient temperature of base station and epitaxial device reaches a certain numerical value, the base station will be reported to base station controller to the information that number of users is controlled by external interface, described base station controller reduces the caloric value of base station itself according to described information by the control number of users that can insert, and makes the base station also can operate as normal under higher temperature.
Described base station will be reported to base station controller to the information that number of users is controlled by external interface, the measure that the number of users that described base station controller can insert by control according to described information reduces the caloric value of base station itself is specially: but by between the maximum access customer number amount of an a certain ambient temperature of setting and correspondence, setting up the contrast algorithm, when the ambient temperature in the base station reaches a certain ambient temperature that sets, but restriction base station actual user's number is no more than this maximum access customer number amount.
Described base station will be reported to base station controller to the information that number of users is controlled by external interface, the measure that the number of users that described base station controller can insert by control according to described information reduces the caloric value of base station itself is specially: along with improving constantly of ambient temperature, the number of users that base station and epitaxial device are supported reduces gradually.
Described ambient temperature is to obtain by the output that central processing unit regularly reads the plurality of temperature transducer that is arranged on each key point of base station.
The number of users that described control can insert is specially: at first, central processing unit cuts out the BTS service passage of some; Then, will be reported to base station controller to the information that number of users is controlled by the base station external interface.
Described epitaxial device comprises: the tower of base station far-end module, far-pulling module, repeater or band power amplifier is put.
Utilize method of the present invention, after ambient temperature improves, can reduce the number of users tenability of base station gradually, but not the service that directly stops, therefore, can under higher ambient temperature, keep service, solve the problem that minority area surroundings temperature higher base station of minority time can not continue to serve.
Description of drawings
Fig. 1 is for utilizing the ambient temperature schematic diagram of temperature sensor base stations detected and epitaxial device in the embodiment of the invention.
Fig. 2 is a power control circuit control principle schematic diagram in the embodiment of the invention.
Fig. 1 is the schematic diagram that a base station and epitaxial device utilize temperature sensor testing environment temperature.Described base station epitaxial device, the tower that includes base station far-end module, far-pulling module, repeater, band power amplifier is put etc.
As shown in Figure 1, inside of base station includes a plurality of temperature sensors, is placed on the different positions, so that obtain the temperature conditions of each key point.Quantitatively generally comprise the covering of following three points at least: the temperature of ambient temperature, inside of base station power tube case temperature, the relative maximum temperature point of other circuit of inside of base station.The position of putting is for obtaining the true temperature of test point as much as possible, and the place of promptly pressing close to most test point is provided with temperature sensor.These transducers have a temperature measurement range, degree for example-40～+ 85, and the resolution of temperature is at 1～2 degree, and the cycle that output reports central processing unit was at 5～60 seconds frequency.Suppose that the base station is+55 degree full capacity work designs according to ambient temperature, when ambient temperature rise to+55 the degree after, the base station begins to control the number of users that can insert, when number of users does not have near specified number of users, the number of users controlled function is not started to control, when number of users during, limit new user's access near the maximum quantity that can bear.Determine that an access customer number amount under the temperature value can obtain with certain algorithm, relevant with current ambient temperature, the key point temperature of inside of base station monitoring, the power grade of base station etc.The base station needs control to reduce number of users according to each relevant information decision, until ambient temperature rises to till the ambient temperature that is designed under the minimum user situation, work is closed in the base station, stops service.
The number of users control algolithm, can realize by following formula:
Suppose that 60% of total power consumption is that it doesn't matter with number of users, 40% is directly proportional with number of users, and temperature rise is 25 degree when supposing maximum power dissipation, and maximum operating temperature is 55 degree under the maximum number of user, then has:
Hear rate percentage=(0.6+0.4* user's percentage);
High ambient temperature=the 55+ (25/ hear rate percentage) of work after the improvement-25=55+ (25/ (0.6+0.4* user's percentage))-25;
So, Current Temperatures=55+ (25/ (0.6+0.4* user's percentage))-25;
Obtain: user's percentage=62.5/ (Current Temperatures-30)-1.5 (55＜Current Temperatures＜70).
The base station reduces to support number of users under the high temperature, is to realize that by the BTS service passage that central processing unit cuts out some as shown in Figure 2, central processing unit is controlled the required working power of each service channel of base station by a power control circuit.The present invention is just because of by closing the circuit supply that some no longer need work, and circuit itself is because the power consumption that the decline of number of users brings descends, thereby can obtain the decline of complete machine caloric value.
Fig. 3 is the flow chart of the inventive method.As shown in the figure, when ambient temperature is lower than 55 when spending, do not carry out the control of limited subscriber; When ambient temperature is higher than 70 when spending, close the base station; And when ambient temperature is between 55 degree and 70 degree, then number of users is controlled, make number of users that the base station can insert smaller or equal to supported number of users under the current environmental temperature.The current environmental temperature maximum can support number of users to obtain by aforementioned algorithm.
When the base station is controlled number of users, be reported to base station controller by the base station external interface, so that feed back current base station is implemented control to number of users information.
When ambient temperature raise, the present invention inserted quantity by reducing the user, and the caloric value of base station itself is descended, and made the base station also can keep operate as normal under higher temperature.
Be an example below.Table one is depicted as the table of comparisons of the number of users of cdma base station of one 64 tunnel voice pathway and complete machine power etc., and as seen from table, along with the minimizing of number of users, various power and complete machine hear rate all will descend.
Table one:
| User's percentage | Power amplifier power | Other power | Complete machine power | Transmitting power | The complete machine hear rate | Hear rate percentage |
| 100％ | 250W | 200W | 450W | 20W | 430W | 100％ |
| 50％ | 175W | 150W | 325W | 10W | 315W | 73％ |
