Embodiment 1

[0017] Please refer to figure 1 , an embodiment of the present invention provides a method for controlling output power of roadside unit equipment, the method comprising:

[0018] 110. Obtain a threshold corresponding to the current power level.

[0019] The roadside unit equipment is provided with multiple power levels, and each power level corresponds to a different output power. Each output power can be converted into a corresponding voltage value according to a certain conversion relationship, that is, the power can be represented by a voltage value. In practical applications, the output power corresponding to each power gear will change with the change of the ambient temperature, and the converted voltage value will also change accordingly.

[0020] In this embodiment, a power-voltage relationship table is first made at normal temperature, and each power gear and the voltage value corresponding to the output power of the power gear at normal temperature are identified i...

Embodiment 2

[0047] Please refer to Figure 4 , the present invention provides a roadside unit equipment output power control device, comprising:

[0048] The first acquisition module 410 is configured to acquire the threshold corresponding to the current power level;

[0049] The second acquiring module 420 is configured to acquire the actual output power under the current power gear, and convert the actual output power into a first voltage value;

[0050] The adjustment module 430 is configured to judge whether the first voltage value exceeds the threshold value, and if so, gradually adjust the output power according to the set step size until the first voltage value is within the threshold value range.

[0051] Optionally, the device further includes: a third acquisition module; the third acquisition module is configured to acquire a power compensation value corresponding to the current ambient temperature; the adjustment module is also configured to output the power compensation value...

Embodiment 3

[0056] The embodiment of the present invention also provides a roadside unit device, which includes the device as described in the second embodiment.

[0057] Those of ordinary skill in the art can understand that all or part of the steps in the various methods of the above-mentioned embodiments can be completed by hardware, and can also be completed by program instructions related to hardware, and the program can be stored in a computer-readable storage medium. The storage medium may include: read-only memory, random-read memory, magnetic disk or optical disk, and the like.

Abstract

The invention discloses a method for controlling output power of roadside unit equipment, comprising: obtaining a threshold value corresponding to a current power gear; obtaining an actual output power under the current power gear, and converting the actual output power into a first voltage value ; if the first voltage value exceeds the threshold value, the output power is gradually adjusted according to the set step size until the first voltage value is within the threshold value range. Embodiments of the present invention also provide corresponding devices and roadside unit equipment. The technical scheme of the present invention reduces the interference of the ambient temperature on the output power, realizes the stable control of the output power, and can avoid a large change in the transaction distance.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for controlling output power of roadside unit equipment and roadside unit equipment. Background technique [0002] Intelligent Transportation System (Intelligent Transport System, ITS) is a modern transportation technology that integrates communication, control, transportation, computer and other technologies. Dedicated Short Range Communication (DSRC) technology is used in the intelligent transportation system to realize communication between On Board Unit (OBU) equipment and Road Side Unit (RSU) equipment. [0003] However, in practical applications, the transmit power of the RSU will change with the change of the ambient temperature, which will change the transaction distance and affect the normal traffic. Contents of the invention [0004] Embodiments of the present invention provide a method and device for controlling the output powe...
