具体实施方式
为使本公开实施例的上述目的、特征和优点能够更加明显易懂,下面将结合本公开实施 例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述。需要说明的是,在不冲突的情况下,本公开中的实施例及实施例中的特征可以相互任意组合。
下面将结合附图对本公开的技术方案进行详细说明。
本公开实施例提供的温度控制方法,该温度控制方法应用于CPE终端,该方法可以包括:在终端通电后,检测终端的温度;当终端的温度超过预设温度阈值时,开启调制解调模块,并根据终端的温度以及调制解调模块自身的功率,控制加热阵列模块输出对应的加热功率对终端进行加热。
实施例1
图1是本公开实施例的应用于CPE终端的温度控制方法流程示意图,下面将参考图1,对本公开实施例的温度控制方法进行详细描述。
首先,在步骤101,在终端通电后,检测终端的温度。
在一些示例性的实施方式中,在终端通电以后,可以利用温度检测模块通过温度传感器实时检测终端当前的温度。
在一些示例性的实施方式中,实时检测终端的调制解调模块的温度作为该终端温度的代表。
在一些示例性的实施方式中,温度检测模块将检测到的终端当前的温度结果,分别发送给温度比较模块和调制解调模块。
在步骤102,当终端的温度超过预设温度阈值时,开启调制解调模块,并根据终端的温度以及调制解调模块自身的功率,控制加热阵列模块输出对应的加热功率对终端进行智能加热。
在一些示例性的实施方式中,温度比较模块将检测到的终端的温度与预设温度阈值进行比较,并将比较结果传给调制解调模块。
在一些示例性的实施方式中,在终端通电后但未开机的情况下,当温度传感器检测到终端当前的温度低于预设的第一温度阈值时,先对终端进行全速加热处理,以使得终端温度以最快速度上升。在此情况下,如终端温度经过全速加热后超过预设的第一温度阈值时,终端开机,可以触发开启调制解调模块进行智能加热。例如,如果此时温度高于第二温度阈值,可以控制加热阵列模块停止加热,仅依靠终端的自身工作负荷所产生的热量维持环境温度。如果此时温度有再次低于第一温度阈值,调制解调模块可以依据自身当前功耗来开启对应功率的加热阵列模块进行加热。
在一些示例性的实施方式中,检测终端的数据(比如:温度、电流等等)为通过检测调制解调模块获得。
在一些示例性的实施方式中,预设的第一温度阈值略高于终端的最低工作温度;如,终端的最低工作温度为0℃,第一温度阈值则可以设为5℃。将预设的第一温度阈值设计为略高于终端的最低工作温度是为了使终端能够处在舒适的工作温度环境中,终端能够有更好的工作状态。
在一些示例性的实施方式中,在温度传感器检测到终端当前的温度不超过预设的第一温度阈值时,且终端当前为已开机状态时,不再对终端重复下达开机指令,而是根据当前终端的功耗智能控制当前的加热功率,使得加热的功率与终端的功耗之和不大于终端的电源总功率(即,进入智能加热模式)。这样可以在终端处于舒适的工作温度环境中的同时,也兼顾到了终端的安全负载的问题。经试验,采用该方法的终端可以在0℃至-40℃的温度环境中保证正常工作性能。
在一些示例性的实施方式中,终端处于工作状态时的功耗由终端的电流检测模块通过实时检测电流并加权计算获得。
在一些示例性的实施方式中,终端的电流检测模块通过电流传感器检测当前电流值,并将该检测数据传给调制解调模块,调制解调模块根据该电流传感器检测到的数据开通通过上述计算获得的对应功率的加热阵列模块;即,终端自身功耗越小,则开通的加热单元功率越大;反之终端自身功耗越大,则开通的加热单元功率越小。这样,既可以保证设备温度快速上升,又可以保证终端自身功耗和开通的加热单元的加热功率形成的总功率不会超过系统电源模块的总输出功率。
应说明的是,上述方法可以以软件、硬件或软硬件结合的方式在终端上运行,以实现对终端的智能加热,或者运行于与终端连接的其他设备上,来实现对终端的加热。
本公开实施例还提供一种温度控制系统,该系统应用于CPE终端,该系统可以包括:温度检测模块,温度检测模块用于通过温度传感器检测终端的温度;温度比较模块,温度比较模块将检测到的终端的温度与预设第一温度阈值进行比较,并将比较结果传给调制解调模块;调制解调模块,当终端的温度超过第一温度阈值时,对调制解调模块通电,并控制加热阵列模块对终端进行加热。

实施例4
图4是本公开实施例的应用于CPE终端的温度控制方法的一个实施方式的具体流程示意图,下面将结合图4,对本公开实施例的应用于CPE终端的温度控制方法进行详细描述。
首先,在步骤401,系统电源模块上电。
本公开实施例中,系统电源模块首先提供启动电源。
步骤402,终端当前温度是否高于预设第一温度阈值。
在一些示例性的实施方式中,温度检测模块通过温度传感器检测终端当前的温度,并将获得的温度值与预设的温度阈值进行比较,判断其是否高于预设的温度阈值;若判断结果为是,则进入步骤404;若判断结果为否,则进入步骤403。
步骤403,满负荷加热。
在一些示例性的实施方式中,当检测到终端当前温度低于预设第一温度阈值时,加热模块满负荷运作,即进入全速加热模式,终端按照预设加热功率阈值进行加热。并且回到步骤402继续对当前终端进行温度检测,以防止当前终端温度过高,影响设备性能或寿命。
步骤404,调制解调模块触发开机并进入智能加热模式。
在一些示例性的实施方式中,智能加热模式为进入步骤417或进入步骤405。
步骤405,实时采集电流数据,并计算终端当前的功耗,按照Ps*(1-η)-U*I计算拟开通的加热单元功率。
在一些示例性的实施方式中,调制解调模块根据电流检测模块实时采集的电流数据,并 经过加权计算调制解调模块自身当前平均功耗(平均功耗所计算的时间段长度可由用户设定),并按照Ps*(1-η)-U*I计算拟开通的加热单元功率,其中,Ps为终端的电源模块总的输出功率,η为比例系数,通常η可以设置为80%,U为终端的工作电压,I为检测到的电流值。
步骤406,终端当前温度是否高于预设第二温度阈值。
在一些示例性的实施方式中,温度检测模块通过温度传感器检测到的终端当前温度,并将该温度数值与预设第二温度阈值进行比较,若终端当前温度高于预设第二温度阈值,则进入步骤407;若终端当前温度低于预设第二温度阈值,则进入步骤409或410。
步骤407,温度比较模块输出高电平。
在一些示例性的实施方式中,终端当前温度高于预设温度阈值时,温度比较模块对或门逻辑模块输出高电平。
步骤408,调制解调模块关闭加热单元负向接地通道。
在一些示例性的实施方式中,调制解调模块得到当前终端温度高于预设温度阈值的信号,关闭加热模块,此时依靠终端自身功耗带来的热量维持环境温度,并进入步骤416。
步骤409,温度比较模块输出低电平。
在一些示例性的实施方式中,终端当前温度低于预设温度阈值时,温度比较模块对或门逻辑模块输出低电平。
步骤410,调制解调模块打开Ps*(1-η)-U*I加热功率单元负向接地通道。
在一些示例性的实施方式中,因为当前温度低于预设温度阈值,因此需要继续加热模块加热,由于此时是已开机状态,所以需要考虑系统电源模块总的功率负载,因此仅开启Ps*(1-η)-U*I的加热功率单元负向接地通道。即,不是使得系统电源模块满负载状态,而且取用一定的系数,需要进入加热工作状态的加热单元负载功率选择为Ps*(1-η)-U*I。其中,Ps为终端的电源模块总的输出功率,η为比例系数,通常η可以设置为80%,U为终端的工作电压,I为检测到的电流值。
步骤411,或门输出低电平开通加热模块正向供电通道。
在一些示例性的实施方式中,或门逻辑模块输出低电平(前提是温度比较模块输出低电平,且电流比较模块也输出低电平),此时开通加热模块准备加热。
步骤412,启动Ps*(1-η)-U*I加热功率单元加热动作。
在一些示例性的实施方式中,进行相应的Ps*(1-η)-U*I加热单元进入加热模式。
步骤413,瞬时负载电流是否高于预设电流阈值。
在一些示例性的实施方式中,检测瞬时电流是否高于预设的电流阈值,若判断结果为高于预设的电流阈值,则进入步骤414;若判断结果为低于预设的电流阈值,则回到步骤412,继续加热。
在一些示例性的实施方式中,调制解调模块可以通过检测到的瞬时电流值调整加热阵列模块的加热功率,加热功率可以为预设功率阈值减去瞬时电流值对应的终端的工作负载,预设功率阈值小于终端的电源总输出功率。
步骤414,电流比较模块输出高电平。
在一些示例性的实施方式中,此时出现电流高于电流阈值的情况,将该情况发送给或门逻辑模块。
步骤415,或门逻辑模块输出高电平。
在一些示例性的实施方式中,因为电路中出现电流高于电流阈值的情况,为了保证终端的安全性,需要将这一情况上报调制解调模块。
步骤416,断开加热动作。
在一些示例性的实施方式中,因为电流高于预设电流阈值,所以需要断开加热模块,以保证电路安全,此时系统电源模块不给加热模块供电。此时重新回到步骤404,进入智能加热模式循环检测。
步骤417,瞬时负载电流是否高于预设电流阈值。
在一些示例性的实施方式中,电流检测模块通过电流传感器检测电路中瞬时电流是否有高于预设电流阈值的情况出现,如高于电流阈值,则进入步骤414;若低于电流阈值,则进入步骤418。
步骤418,电流比较模块输出低电平。
在一些示例性的实施方式中,电流检测模块通过电流传感器检测电路中瞬时电流未有高于预设电流阈值的情况出现,因此电流比较模块对或门逻辑模块输出低电平,进入步骤411。
在一些示例性的实施方式中,或门逻辑模块因为接收到电流比较模块输出的低电平,且温度比较模块给的信号也是低电平,此时或门逻辑模块输出低电平,加热模块可以进入加热模式。
本公开实施例的温度控制方法,通过实时检测终端当前的温度,对CPE终端进行智能加热,控制加热的功率与终端的功耗之和不超过终端的电源总功率,通过利用终端自身功耗带来的热量的同时使得加热功率与终端自身功耗之和始终保持在终端的安全负载范围内;同时,通过检测电流模块防止过载的出现,进一步的保障加热的安全性以及终端负载的安全性。上 述加热方法使得CPE终端在0℃--40℃温度环境中仍然能够正常工作,亦兼顾了终端安全负载的问题,同时解决了采用0℃以下商用芯片所带来的成本增加的问题,保证终端在0℃以下环境温度中也能正常工作。
