- the so-called definition information is information used to characterize which sensor is used to detect which region, the water temperature at the height position.
- the so-called theoretical temperature change order refers to a sequence in which the temperature detected by each temperature sensor largely changes under the above-described definition information when cold water or hot water is injected into the water tank.
- One of the relatively simple definition forms is: the relative mounting positions of the respective temperature sensors are numbered in a certain order, for example, the way in which the height direction of the water tank increases from bottom to top, and the bottommost temperature sensor is the first sensor.
- Adjacent to the first sensor is a second sensor, and then a third sensor, a fourth sensor, etc., in which case the corresponding theoretical temperature change order is the first sensor, the second sensor, the third sensor... .

- cold water refers to water having a lower temperature relative to the current water in the water tank
- hot water refers to water having a higher temperature than the current water in the water tank.
- the temperature sensor located at the lower position of the water tank contacts the cold water first with respect to the temperature sensor of the higher position, so the lower temperature sensor detects a significant decrease in temperature earlier than the temperature sensor of the higher position, thus The order in which the temperature drops drastically reflects the current installation position of each temperature sensor in the water tank.
- the temperature sensor located at the lower position of the water tank contacts the hot water first with respect to the temperature sensor at the higher position, so The low position temperature sensor detects a substantial rise in temperature earlier than the higher position temperature sensor.
- cold water or hot water is not necessarily injected from the lower part of the water tank, and may be injected from the upper part or from both sides. If injected at the top, the temperature sensor at the higher position first senses the change in temperature, and the temperature sensor at the lower position later feels the change in temperature. If injected on both sides, the temperature sensor near the injection port experiences a change in temperature earlier than the temperature sensor far from the injection port.
- the above method can be applied to a hot water system, and the hot water system is generally cold water and hot water, so it is suitable for a monitoring scheme when cold water is injected into the water tank.

In the heating process, hot water is used and cold water is injected. The water temperature change may be complicated, in order to avoid This complication affects the prediction of the relative position of the temperature sensor. It is preferable to perform the above method when the cold water is injected into the water tank after the end of heating, that is, the use phase after the heating of the hot water system is completed. It should be understood that the above method can be used not only for a system such as a hot water system for hot water to enter and exit, but also for a system for hot water to enter and exit a cold water.
- the above process may be referred to as a temperature sensor automatic error correction process, and may be referred to as a temperature sensor automatic error correction program if implemented by software.
- the latest definition information is matched with the current relative position of each temperature sensor, so that the control of the hot water system does not cause an abnormality due to an incorrect installation position of the temperature sensor.
- the manner in which the definition information of each temperature sensor is updated by the present invention is more reliable than the manual distinction in the prior art, and the method of distinguishing different interfaces in the prior art does not need to make a large number of different types of interfaces, and the production organization , after-sales maintenance and preparation of materials, etc. will not cause inconvenience.
- the determining step of the above sequence and the determining step of whether the sequence is consistent with the theoretical temperature change order may be performed only once, and it is determined whether the definition information needs to be updated.
- multiple executions or loop executions can be performed.
- the method may be specifically: when the cold water or the hot water is injected into the water tank, the steps of acquiring the temperature detected by each temperature sensor and determining the sequence are performed cyclically, and after each determining the sequence It is determined whether the sequence is consistent with the currently stored theoretical temperature change order until the number of consecutively determined inconsistencies exceeds a preset number of times, exiting the loop and updating the definition information according to the last determined sequence.
- a counter is provided for counting the number of consecutive determinations that the sequence is inconsistent with the currently stored theoretical temperature drop order.
- the counter is cleared, and then the temperature data detected by each temperature sensor is collected to determine the sequence in which the temperature of each temperature sensor is greatly reduced, and then it is determined whether the sequence is consistent with the currently stored theoretical temperature drop order. If they are inconsistent, the counter is incremented by 1, and then it is judged whether the counter count exceeds the preset number; if the preset number of times is not exceeded, the temperature data detected by each temperature sensor is collected again, and the temperature of each temperature sensor is again determined to be greatly decreased. In order, it is again determined whether the order of the determination is consistent with the current stored theoretical temperature drop order.
- the counter is incremented by one, and then It is judged whether the counter count exceeds the preset number; and so on, when the number of consecutive inconsistencies is determined to exceed the preset number of times, the loop is exited, and the update operation of the definition information is performed.
- the definition information and the theoretical descending order are read in the memory module, and the memory module may be a module in the physical device that executes the method flow, or may be outside the physical device. A module.
- the cycle of the substantially detected temperature changes and the sequence of the theoretical temperature change are determined multiple times by loop or multiple times, thereby avoiding errors caused by errors in a certain data acquisition and improving control accuracy.
- the specific update manner is related to the definition manner of each temperature sensor.
- each temperature sensor is sequentially numbered in the manner of increasing the height direction of the water tank from bottom to top.
- the updating manner may be: sorting the numbers in the definition information of each temperature sensor according to the sequence, to implement updating the definition information.

- the sensor T2 is defined as the second sensor T20
- the first sensor T10 is prior to the second sensor

- the temperature data collected by the two sensors T1 and T2 if it is determined that the sensor T1 is to be cooled significantly before the sensor T2, that is, the sequence and the theoretical temperature are lowered.

- the sensor T1 is defined as the second sensor T20
- the sensor T2 is defined as the first sensor T10.
- the theoretical temperature drop order is still that the first sensor T10 has a large temperature drop before the second sensor T20, and no change occurs.

- One of the optional judging methods is: after the control device of the water tank is powered on, it is determined whether the temperature detected by the temperature sensor starts to decrease, and when it is determined that the temperature detected by the temperature sensor starts to decrease, it is determined that there is a cold water injection station. Said water tank.
- the temperature detected by the temperature sensor is always rising during the heating phase, in the use phase after the heating is completed, with the use of hot water, cold water is injected into the water tank from the cold water inlet, and the temperature detected by the temperature sensor will be It drops, so it can be used to determine if the hot water system is in use.
- the control device of the water tank is powered on, it is determined whether the temperature detected by the temperature sensor starts to rise. If it is determined that the temperature detected by the temperature sensor starts to rise, it can be determined that hot water is injected into the water tank. This method of judgment is simple and reliable.
- the temperature detected by each temperature sensor after power-on may be regarded as a temperature change of 0 ° C, so that even in the heating stage, If the power is turned on, it will not be operated according to the above-mentioned sequence determination, order consistency judgment, etc., and only when the temperature drops, that is, enters the use phase, the above-mentioned sequence determination, order consistency judgment, etc. are performed, It is avoided to perform the above-mentioned sequence determination, order consistency judgment and the like in the heating stage, thereby avoiding error control.

可选的，所述顺序确定模块还用于：

热水系统的控制不会因为温度传感器的安装位置错误而出现异常。通过本发明对各个温度传感器的定义信息更新的方式，相对于现有技术中人工区分的方式更加可靠，相对于现有技术中不同接口的方式区分不需要制作大量不同类型的接口，对生产组织、售后维修备料等都不会造成不便。

附图标记说明：
1-水箱；11-冷水进口；12-热水出口；T1、T2-温度传感器；2-温度传感器监测装置；21-记忆模块。
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，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
第一方面，本发明提供一种水箱的温度传感器监测方法，包括：
S1、在冷水或热水注入水箱时，获取所述水箱内各个温度传感器所检测到的温度，并确定各个温度传感器所检测到的温度的变化速率超过预设速率的先后顺序；
S2、判断所述先后顺序与当前存储的对各个温度传感器的定义信息所对应的理论温度变化顺序是否一致；
S3、在判定为不一致时，根据所述先后顺序对当前存储的所述定义信息进行更新；
其中，在冷水注入水箱时，所述理论温度变化顺序为理论温度下降顺序，所述先后顺序为各个温度传感器所检测到的温度的下降速率超过第一预设速率的顺序；在热水注入水箱时，所述理论温度变化顺序为理论温度上升顺序，所述先后顺序为各个温度传感器所检测到的温度的上升速率超过第二预设速率的顺序。
可理解的是，温度的变化速率超过预设速率，实际上表征温度大幅下降或上升，其中的预设速率可以根据需要自行设置，对此本发明不做限定，通常第一预设速率和/或第二预设速率可以在0.1～2℃/min中选取，例如0.5℃/min。
可理解的是，所谓的定义信息是用来表征哪个传感器用于检测哪个区域、高度位置的水温的信息。所谓的理论温度变化顺序，是指在冷水或热水注入水箱时，在上述定义信息下，各个温度传感器所检测到的温度大幅变化的顺序。其中，定义信息的定义形式可以有多种，对此实施例不做限定。其中一种比较简单的定义形式是：对各个温度传感器的相对安装位置按照某一顺序进行编号，例如沿水箱的高度方向从下至上依次增大的方式编号，最底部的温度传感器为第一传感器，第一传感器之上相邻的是第二传感器，然后依次是第三传感器、第四传感器……，这样的话，对应的理论温度变化顺序为第一传感器、第二传感器、第三传感器……。定义信息和对应的理论温度变化顺序可以存储在执行上述方法的实体模块内，也可以单独存储在一个实体模块内，在需要使用时进行调用。
可理解的是，冷水是指相对于水箱内的当前水温较低的水，热水是指相对于水箱内的当前水温较高的水。
举例来说，若从水箱的下部注入冷水，随着冷水的不断注入，冷水的水位
逐渐上升，位于水箱较低位置的温度传感器相对于较高位置的温度传感器先接触到冷水，所以较低位置的温度传感器相对于较高位置的温度传感器更早的检测到温度的大幅降低，因此温度大幅下降的先后顺序可以反映各个温度传感器在水箱内的当前安装位置。当然，若从水箱的下部注入热水，随着热水的不断注入，热水的水位逐渐上升，位于水箱较低位置的温度传感器相对于较高位置的温度传感器先接触到热水，所以较低位置的温度传感器相对于较高位置的温度传感器更早的检测到温度的大幅上升。
可理解的是，冷水或热水不一定是从水箱的下部注入，也可能从上部注入，或从两侧注入。如果在上部注入，则位于较高位置的温度传感器首先感受到温度的变化，较低位置的温度传感器后来才感受到温度的变化。如果在两侧注入，则靠近注入口的温度传感器要比远离注入口的温度传感器更早的感受到温度的变化。
可理解的是，上述方法可以用于热水系统，热水系统一般是冷水进热水出，因此适合采用冷水注入水箱时的监测方案。热水系统在加热过程中使用热水和在加热完成后使用热水均会有冷水注入水箱，而在加热过程中使用热水的同时也有冷水的注入，其水温的变化可能会复杂，为了避免这种复杂情况影响到温度传感器相对位置的预测，最好在加热结束后冷水注入所述水箱时，即指热水系统加热完成后的使用阶段执行上述方法。应当理解的是，上述方法不仅可以用于热水系统这样冷水进热水出的系统，还可以用于热水进冷水出的系统。
可理解的是，由于上述方法的目的是进行温度传感器自动纠错，因此可以上述过程可以称为温度传感器自动纠错过程，如采用软件实现的话，可以称为温度传感器自动纠错程序。
当在水箱内注入冷水或热水时，水箱内的不同位置的温度传感器会在不同时刻感受到水箱内温度的变化。基于这一点，可确定水箱内各个温度传感器的相对位置，将反应该相对位置的先后顺序与当前存储的理论温度变化顺序进行一致性判断，由于当前的定义信息和当前的理论温度变化顺序是对应的，不同
的定义信息会有不同的理论温度变化顺序。若经判断为一致，说明此时水箱内各个温度传感器的相对位置与当前存储的定义信息相匹配，即各个温度传感器的相对位置没有发生变化，若不一致，则对各个温度传感器的定义信息进行更新，使得最新的定义信息与各个温度传感器当前的相对位置相匹配，从而使得热水系统的控制不会因为温度传感器的安装位置错误而出现异常。通过本发明对各个温度传感器的定义信息更新的方式，相对于现有技术中人工区分的方式更加可靠，相对于现有技术中不同接口的方式区分不需要制作大量不同类型的接口，对生产组织、售后维修备料等都不会造成不便。
在具体实施时，如图1所示，可以对上述先后顺序的确定步骤以及对先后顺序与理论温度变化顺序是否一致的判断步骤均只执行一次，便得出是否需要对定义信息进行更新的判断。当然，为了保证足够的精确度，可以执行多次执行或循环执行。
当采用循环执行的方式时，方法可以具体为：在冷水或热水注入水箱时，循环执行获取各个温度传感器所检测到的温度及确定所述先后顺序的步骤，并在每一次确定先后顺序后判断该先后顺序是否与当前存储的理论温度变化顺序是否一致，直至在连续判定为不一致的次数超出预设次数时，退出循环并根据最后一次确定的先后顺序对所述定义信息进行更新。
以在水箱内注入冷水为例说明上述过程：
参考图2，设置一计数器，用于对连续判定为先后顺序与当前存储的理论温度下降顺序不一致的次数进行计数。在执行控制操作开始时，计数器清零，然后采集各个温度传感器所检测到的温度数据，确定各个温度传感器温度大幅下降的先后顺序，然后判断该先后顺序是否与当前存储的理论温度下降顺序是否一致，若不一致，则计数器加1，然后判断计数器的计数是否超出预设次数；若没有超出预设次数，则再次采集各个温度传感器所检测到的温度数据，再次确定各个温度传感器温度大幅下降的先后顺序，再次判断此次确定的先后顺序是否与当前存储的理论温度下降顺序是否一致，若不一致则计数器再加1，再
判断计数器的计数是否超出预设次数；以此类推，当连续判定为不一致的次数超出预设次数时，则退出循环，并执行定义信息的更新操作。在图3示出的流程中，定义信息和理论下降顺序是在记忆模块中读取的，该记忆模块可以是执行该方法流程的实体装置中的一个模块，也可以是该实体装置之外的一个模块。
这里，通过循环或多次的方式，对实际检测到的温度大幅变化的先后顺序与理论温度变化顺序进行多次判断，避免了某一次数据采集的错误所导致的误差，提高控制精度。
在以在水箱内注入冷水为例进行说明的上述过程中，若在某一次将先后顺序与理论温度下降顺序是否一致的判断中，判断得知两者是一致的，则保持所存储的定义信息不变，计数器不加1，然后返回循环继续执行采集温度数据、确定先后顺序、一致性判断等这些操作。由于只有在连续判定为不一致的次数超出预设次数时，才会退出循环，因此当不满足该条件时，控制器会一直进行循环操作，进行一致性判断，因此一旦出现安装位置有问题，就会检测出来，及时更新。
在具体实施时，在执行对所述定义信息的更新步骤时，具体的更新方式与各个温度传感器的定义方式有关，例如，各个温度传感器沿水箱高度方向从下至上依次增大的方式依次编号，则更新方式可以为：按照所述先后顺序，对各个温度传感器的定义信息中的编号进行排序，以实现对所述定义信息的更新。
下面以图3中热水系统的水箱中设置有两个温度传感器T1和T2的情况进行举例说明：
参考图2，当前存储的定义信息为第一传感器T10和第二传感器T20，且将传感器T1定义为第一传感器T10，传感器T2定义为第二传感器T20，第一传感器T10要先于第二传感器T20出现温度大幅下降，也就是说，定义信息中认为位于水箱1中较低位置的传感器为第一传感器T10，位于水箱1中较高位置的传感器为第二传感器T20。当根据两个传感器T1和T2所采集的温度数据，若确定传感器T1要先于传感器T2出现大幅降温，即先后顺序与理论温度下降
顺序一致，则认为两个温度传感器在水箱1中的安装位置没有错误。但是如果确定的结果是传感器T1要晚于传感器T2出现大幅降温，即先后顺序与理论温度下降顺序不一致，说明两个温度传感器在水箱中的高度顺序发生了调换，这时对定义信息进行更新：将传感器T1定义为第二传感器T20，传感器T2定义为第一传感器T10，此时理论温度下降顺序还是第一传感器T10要先于第二传感器T20出现温度大幅下降，没有发生变化。虽然在图3中示出的流程图中，以循环的方式执行，但是若选择只执行一次的先后顺序确定和一致性判断过程，则可以将预设次数设置为0。通过上述过程，可以对两个传感器进行纠错，避免错误的定义信息造成控制混乱。
在具体实施时，需要首先判断水箱当前是否注入热水或冷水，当应用至热水系统时甚至需要判断热水系统是否进入加热完成后的使用阶段，具体的判断方法有多种，对此本发明不做限定。其中一种可选的判断方法为：在水箱的控制装置上电后判断是否有温度传感器所检测到的温度开始降低，在判定有温度传感器所检测到的温度开始降低时，确定有冷水注入所述水箱。由于在加热阶段，温度传感器所检测到的温度是一直上升的，在加热完成后的使用阶段，随着热水的使用，会有冷水从冷水进口注入水箱，此时温度传感器检测到的温度会下降，因此可以用来判断热水系统是否进入使用阶段。对应的，在水箱的控制装置上电后判断是否有温度传感器所检测到的温度开始上升，若判定有温度传感器所检测到的温度开始上升，则可以确定有热水注入所述水箱。这种判断方式简单、可靠。
在具体实施时，假如上述方法应用在热水系统中，还可以将在上电后各个温度传感器所检测到的温度上升或不变的情况视为温度变化为0℃，这样即便在加热阶段，上电的话，也不会根据进行上述先后顺序的确定、顺序一致性判断等操作，只有在温度下降时，即进入使用阶段，才会执行上述先后顺序的确定、顺序一致性判断等操作，以避免在加热阶段便进行上述先后顺序的确定、顺序一致性判断等操作，从而避免出现错误控制。同样的，当上述方法引用于
热水进冷水出的系统中时，可以将在上电后各个温度传感器所检测到的温度下降或不变的情况视为温度变化为0℃，以避免错误控制。
第二方面，本发明还提供一种水箱的温度传感器监测装置，该装置包括：
顺序确定模块，用于在冷水或热水注入水箱时，获取所述水箱内各个温度传感器所检测到的温度，并确定各个温度传感器所检测到的温度的变化速率超过预设速率的先后顺序；
一致性判断模块，用于判断所述先后顺序与当前存储的对各个温度传感器的定义信息所对应的理论温度变化顺序是否一致；
定义更新模块，用于在判定为不一致时，根据所述先后顺序对当前存储的所述定义信息进行更新；
其中，在冷水注入水箱时，所述理论温度变化顺序为理论温度下降顺序，所述先后顺序为各个温度传感器所检测到的温度的下降速率超过第一预设速率的顺序；在热水注入水箱时，所述理论温度变化顺序为理论温度上升顺序，所述先后顺序为各个温度传感器所检测到的温度的上升速率超过第二预设速率的顺序。
可理解的是，本发明第二方面提供的温度传感器监测装置实际上与第一方面中提供的温度传感器监测方法相对应，其有关内容可选实施方式可以参考第一方面中的相应内容，例如：所述顺序确定模块具体用于：在冷水或热水注入水箱时，循环执行获取各个温度传感器所检测到的温度及确定所述先后顺序的步骤；所述一致性判断模块具体用于：在所述顺序确定模块每一次确定先后顺序后判断该先后顺序是否与当前存储的理论温度变化顺序是否一致；所述定义更新模块具体用于：在连续判定为不一致的次数超出预设次数时，使所述顺序确定模块退出循环并根据最后一次确定的先后顺序对所述定义信息进行更新。
再例如，所述定义更新模块具体用于：按照所述先后顺序，对各个温度传感器的定义信息中的编号进行排序，以实现对所述定义信息的更新。

或者，在水箱的控制装置上电后判断是否有温度传感器所检测到的温度开始上升，在判定有温度传感器所检测到的温度开始上升时，确定有热水注入所述水箱。

若冷水注入水箱，则将在上电后各个温度传感器所检测到的温度上升或不变的情况视为温度变化为0℃；
若热水注入水箱，则将在上电后各个温度传感器所检测到的温度下降或不变的情况视为温度变化为0℃。
再例如，所述第一预设速率和/或所述第二预设速率为0.1～2℃/min。

如图3所示，热水系统中的热水出口12设置在水箱1的上部，冷水进口11设置在水箱的下部，也就是说，冷水从冷水进口11注入水箱1，热水从上方的热水出口12流出。
