屯子 的射頻增益控制方法、 裝置和屯子 木領域  Dice RF gain control method, device and tweezers
本 涉及 通信 木, 尤其涉及 屯子 的射頻增益控制方 法、 裝置和屯子 。 背景 木  This is related to communication wood, especially the RF gain control method, device and tweezers of tweezers. Background
目前, 以RF ( ado Feq e cy de Hca o , 射頻 ) 的 統逐漸在高速公路等智能交通領域得到了 。 以高速公路的 路往 別 統 ,RF 統由路側 、 器和屯子 三部分組成。 在高速公路 , 通 羊道 完成屯子 的 信息 在高速 公路上, 屯子 路側 的信息交互工作, 保存必要的路往信息 在高速公路出 , 屯子 將已 存儲的路往信息 上 , 由羊道軟件完成上 的外 。  At present, the RF (ado Feq e cy de Hca o , RF) system has gradually gained access to intelligent transportation such as highways. The highway is divided into three parts: the road side, the device and the raft. On the expressway, Tongyang Road completes the information of the raft on the expressway, and the information on the side of the rafter works interactively, and saves the necessary roads to the information on the expressway. The scorpion will store the stored road information, which is completed by the sheep road software. Outside.
在高速公路的路往 別 統中, 屯子 的射頻接收信 主要未自路 側 和出 的 。 由于各 的路側 和 的射頻 功率存在較大差別, 而且屯子 路側 或 的通信 也 不 固定, 所以屯子 的射頻接收信 也是強弱不定。  In the roads of the expressway, the radio frequency receiving letters of the dice are mainly not from the road side and out. Since the RF power of each road side and the RF power are different, and the communication on the side of the dice is not fixed, the radio frequency receiving signal of the dice is also strong and weak.
本 明 , 于 介接收 敏度固定的屯子 未說, 果 屯子 本身的接收 敏度很高, 在接收信 的強度也很大的 , 就 引起 接收飽和, 而 不能接收到所需的信 , 降低射頻通信的 性能 果屯子 本身的接收 敏度 低, 可能 在接收信 的強度 不足的 漏掉 希望接收的信 , 同 降低射頻通信的性能。 內容 Benming, the receiving scorpion with fixed sensitivity is not said, the receiving sensitivities of the scorpion itself are very high, and the receiving signal is also very strong, causing reception saturation, but not receiving the required signal, reducing the radio frequency. The performance of the communication is low, and the receiving sensitivity of the signal itself is low, and the signal that is desired to be received may be missed when the strength of the received signal is insufficient, and the performance of the radio communication is lowered. content
有 于此, 本 的主要目的在于提供 屯子林 的射頻增 益控制方法、 裝置和屯子林 , 以 屯子林 的天敏度, 而 提高通信 統的性能。  In view of this, the main purpose of this is to provide the RF gain control method, device and gardenia forest of Zizilin, and improve the performance of the communication system with the sensitivity of the forest.

本 提供 屯子林 的射頻增益控制方法、 裝置和屯子林 , 屯子林 射頻增益控制的 是 屯子林答中的 P 射頻 的射 頻 參數的配置, 射頻 的射頻 參數配置 最低 , 屯子林 的射頻增益最大, 接收 敏度也最高, 射頻 的射頻 參數的配置 越大 , 屯子林 的接收 敏度就越低。 The radio frequency gain control method, the device and the scorpion forest of the scorpion forest are provided, and the RF gain control of the scorpion forest is the configuration of the radio frequency parameter of the P radio frequency in the scorpion forest answer, the radio frequency parameter configuration of the radio frequency is the lowest, the radio frequency gain of the scorpion forest is the largest, the receiving sensitivity Also the highest, RF configuration of the RF parameters The larger the scorpion forest, the lower the reception sensitivity.
由于 的 功率以及屯子林 和 的 不同, 所以在相 同的射頻 下, 屯子林 接收到的信 的功率也是不同的, 了使 得屯子林 在較佳的 工作, 則需要 找到較佳的 。  Because of the difference in power and the difference between the scorpion and the forest, the power received by the scorpion forest is different under the same radio frequency. Therefore, the better the work of the scorpion forest is, the better it needs to be.
本 提供的屯子林 射頻增益控制方法就是 于  The scorpion forest RF gain control method provided by this is

The RF, the RF configuration RF will work in the RF mode, which can make the scorpion forest and better communication. Because they all use the RF work that is more compatible with this, the purpose of the scorpion forest is improved and the performance of RF communication is improved.
1 所示, 本 提供的屯子林 的射頻增益控制方法主要 包括 下步驟  As shown in Figure 1, the RF gain control method provided by the present invention mainly includes the following steps.
S 1、在 屯子林答中的射頻 接收到 的信 , P 將屯子林答中的射頻 偵所模式 其中, 偵所模式 于偵所 得 的RSS 值的模式, 包括 、 路側 等 屯 子林 信息交互的 各。  S1. The received signal from the radio in the Zizilin answer, P will be the radio frequency detection mode in the Zizilin answer. Among them, the mode of the RSS value of the detective mode is detected, including the information exchange between the roadside and the like.
屯子林答中的射頻 接收到 的信 , 立即向 P 介中 , P 在接收到 中 , 則可以 射頻 接收到 了 的信 。  The letter received by the radio in the scorpion forest answer is immediately sent to P, and when P is received, the signal can be received by the radio.

S1 3、 將S1 2中 得符合 定要求的 SS 射頻 的射頻 參數作力工作射頻 參數配置 射頻 , 將射頻 工作模 式。 S1 3. Configure the radio frequency parameters of the SS radio that meet the requirements in S1 2 to work on the radio frequency parameters and configure the radio frequency to operate the radio frequency.
其中, 2所示, S 1 休包括 下步驟 Wherein, 2 shows that S 1 Hugh includes the following steps
S 11、 在 屯子林 的射頻 接收到 的信 , P 向射頻 配置命令, 使其 以配置各相 的射頻參數, P 按照 需要 射頻 配置 方式和 速率等參數  S11. The signal received by the radio frequency of the scorpion forest, P is configured to the radio frequency to configure the radio frequency parameters of each phase, P according to the required radio frequency configuration mode and rate parameters.
S 012 CP 將射頻 的模式 定力 于偵所 得 RSS 值的偵所模式, 其中, 偵所模式中的載波偵所的 介固定數值5 即可, 可以將 最低, 以使得載波偵所 于最 的  S 012 CP fixes the mode of the radio to the detection mode of the detected RSS value, wherein the carrier detective in the detective mode has a fixed value of 5, which can be the lowest, so that the carrier is detected at the most
S 13 CP 將射頻 的射頻 參數 配置 最低,再使得射頻 射頻接收 。  The S 13 CP minimizes the RF parameters of the RF and allows the RF to be received.
在S1 2中, P 每次在 射頻 參數 ,都需要先使得射頻  In S1 2, P needs to make the RF first every time in the RF parameters.
, 再配置射頻 的射頻 參數, 配置完成 , 再使得0 射頻接收 。  Then, configure the radio frequency parameters of the radio, complete the configuration, and then make 0 radio receiving.
射頻 在 接收 即可接收到 的信 , 射頻 在接收到 的信 , 立即向 P 中 , 將 的 RSS RSS 寄存器中, P 在接收到中 , 即可 RSS 寄存器中的值, 即 于 前 未非, 射頻 在 前射頻5 參數下的RSS 。 由于不同 家生 的射頻 在RSS 寄存器中 的 SS 值不 定相同, 但是 射頻 都 有將 換算 通用功率羊 dB 的公式, P 在 RSS 寄存器中的RSS , 可以 公式將 的RSS 換算 通用功率羊 , 再 行下 步的 。 The RF can receive the received signal, the received signal in the RF, immediately to P, in the RSS RSS register, P is received, and the value in the RSS register can be used. RSS under the pre-RF 5 parameters. Because different home RFs are in the RSS register The SS value is not the same, but the RF has a formula that will convert the general power sheep dB, P RSS in the RSS register, the formula can convert the RSS to the general power sheep, and then proceed to the next step.

In the case of receiving the radio frequency, the pre-determination determines that the radio frequency is not received, that is, if no RSS is obtained, the pre-element RSS is used as the RSS of the pre-empower RF parameter.
射頻 的射頻 參數。 RF parameters of the RF.
RSS 可以 定力 介特殊的 或數值, 不 符合 定 要求的 RSS 值的 , 或者也可以將 RSS 定力 的期望值 的 最大的值, 就排除了 偵所到 的射頻 參數。  RSS can be used to determine the specific or value, does not meet the required RSS value, or can also limit the maximum value of RSS's expected value, thus eliminating the RF parameters detected.
在S1 2中, 得RSS 以及 符合 定要求的RSS ,通常先 將射頻 的射頻 參數 預先 的各 射頻 參數列表或者 射頻 參數 同中的最小 , 以使得接收 敏度最大, 在每次 , 預先 的各 射頻 參數列表或 , 逐步增大屯子林答中 射頻 的射頻 參數, 降低射頻 的接收 敏度。  In S1 2, the RSS and the RSS that meet the requirements are usually the smallest of the RF parameter list or the RF parameter in advance of the radio frequency parameter, so that the receiving sensitivity is the largest, at each time, the pre-RF The parameter list or, gradually increase the RF parameters of the RF in the scorpion forest answer, and reduce the receiving sensitivity of the RF.
得RSS 以及 符合 定要求的RSS 可以 下方法 得 介RSS , 得的RSS 和預先 的期望值的 , 參數 的 SS , 定方 最小的RSS 符合 定要求的RSS 。  RSS and RSS that meet the requirements can be RSS-enabled, RSS and pre-expected values, SS of parameters, and minimum RSS are compliant with the required RSS.
