It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
In accordance with an embodiment of the present application, there is provided an embodiment of a device control method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a schematic flow chart of a device control method according to an embodiment of the present application, and as shown in fig. 1, the method at least includes steps S102-S106, where:
step S102, detecting positive electrode temperature data of a battery plug of a battery module in target equipment through a first temperature sensor to obtain a first detection result.
And step S104, detecting the negative temperature data of the battery plug through a second temperature sensor to obtain a second detection result.
In an alternative embodiment of the present application, the first temperature sensor is disposed at the positive electrode of the battery plug and is used for collecting the positive electrode temperature of the battery plug; the second temperature sensor is arranged at the negative pole of the battery plug and used for collecting the temperature of the negative pole of the battery plug. Specifically, the temperature sensor may be directly attached to the battery plug, as shown in fig. 2, the positive electrode temperature sensor is directly attached to the positive electrode of the battery plug, the negative electrode temperature sensor is directly attached to the negative electrode of the battery plug, and the temperature sensor can directly acquire the most accurate temperature data of the battery plug.
When the positive temperature data is detected through the first temperature sensor to obtain a first detection result, whether the first temperature sensor acquires the positive temperature of the battery plug needs to be judged, and if so, the first temperature detection result is determined to be that the positive temperature of the battery plug is in a normal state; if not, determining the first temperature detection result as that the anode temperature is in an abnormal state; similarly, when the second temperature sensor detects the negative temperature data of the battery plug to obtain a second detection result, whether the second temperature sensor acquires the negative temperature of the battery plug needs to be judged, and if so, the second temperature detection result is determined to be that the negative temperature of the battery plug is in a normal state; if not, determining the second temperature detection result as that the cathode temperature is in an abnormal state.
It should be noted that, because the first temperature sensor and the second temperature sensor may fail to detect the temperature of the battery plug due to a fault, the first temperature detection result and the second temperature detection result in the embodiment of the present application do not only include a specific temperature value, but need to first determine whether the temperature sensor collects the temperature of the battery plug, and if the temperature is detected, record the detection result as normal, and record the temperature as the detection result; if the temperature is not detected, the temperature sensor is considered to have a fault, and the detection result is recorded as an abnormal value instead of a specific temperature value.
And step S106, controlling the target equipment together according to the first temperature detection result and the second temperature detection result.
The control of the target device mainly controls the battery module to continue to supply power or stop supplying power.
In an optional embodiment of the present application, a specific process of jointly controlling the target device according to the first temperature detection result and the second temperature detection result is as follows:
if the first temperature detection result is that the anode temperature is in an abnormal state, and the second temperature detection result is that the cathode temperature is in an abnormal state, controlling the battery module to stop supplying power;
if the first temperature detection result is that the anode temperature is in a normal state, and the second temperature detection result is that the cathode temperature is in a normal state, whether the anode temperature and the cathode temperature are within a preset temperature range is judged:
if one or both of the anode temperature and the cathode temperature are not in the preset temperature range, controlling the battery module to stop supplying power to the target equipment;
if the anode temperature and the cathode temperature are both in a preset temperature range, calculating the temperature difference between the anode temperature and the cathode temperature; if the temperature difference is larger than a preset temperature difference threshold value, controlling the battery module to stop supplying power; and if the temperature difference is smaller than the preset temperature difference threshold value, controlling the battery module to continue to supply power.
Specifically, if the positive electrode and the negative electrode of the battery plug are in abnormal states at the same time in the detection result, it is indicated that the temperature sensors of the positive electrode and the negative electrode of the battery plug have faults at the moment, and the temperature detection of the battery plug cannot be completed, and if the temperature state of the battery plug cannot be determined during the use of the device, it is dangerous, and therefore, the battery module needs to be controlled to stop supplying power in such a case.
If the temperatures of the positive electrode and the negative electrode of the battery plug can be normally detected, the temperatures of the positive electrode and the negative electrode need to be compared. Fig. 3 is a simplified circuit diagram of a battery powering a device, the heat Q generated being related to the current I passed, the resistance R of the conductor and the energization time t according to joule's law: q ═ I2Rt, because the current of the series circuit is equal everywhere and the internal resistances of the positive and negative electrodes of the battery plug are close, the heat productivity of the positive and negative electrodes of the battery plug is basically the same when the battery is in use, namely the positive electrode temperature T+And the temperature T of the negative electrode-Should be substantially similar, both should be within the battery plug temperature range [ T1, T2] during normal operation of the device]If one pole is not in the normal temperature range, the pole is in fault, and the battery module is controlled to stop supplying power in order to ensure the safety of the equipment. For example, if it is detected that the temperature of a certain electrode of the battery plug is too high, it indicates that the internal resistance of the certain electrode is large, and it can be determined that the certain electrode has a problem of damage or aging.
If the positive electrode temperature T+And the temperature T of the negative electrode-Are all in the normal temperature range [ T1, T2]]In the method, whether the temperature difference between the two satisfies a preset temperature difference threshold value delta T, i.e. | T+-T-If the temperature difference between two poles is too large, the fault of at least one pole of the battery plug can be judged to a certain degree, and the battery is instructed to stop supplying power in order to ensure the safety of equipment; and only when the anode temperature T + and the cathode temperature T-are both in the normal temperature range and the temperature difference between the anode temperature T + and the cathode temperature T-is smaller than the temperature difference threshold value, the plug of the battery can be judged to be normal, and the battery is indicated to continue to supply power.
In the embodiment of the application, it is considered that the target device may be in different operation states, and in different operation states, the obtained control method is different according to the first temperature detection result and the second temperature detection result. Specifically, if the first temperature detection result and the second temperature detection result satisfy one of the following conditions, the current operation state of the target device needs to be determined: the first temperature detection result indicates that the anode temperature is in an abnormal state, and the second temperature detection result indicates that the cathode temperature is in a normal state; or the first temperature detection result indicates that the anode temperature is in a normal state, and the second temperature detection result indicates that the cathode temperature is in an abnormal state; at this time, the control method of the device needs to be determined together according to the current operating state (which is one of the power-on state and the operating state) of the target device, and the determining process is as follows:
if the equipment is in a starting state at present, directly controlling the battery module to stop supplying power;
if the target device is in a working state currently, the first temperature detection result indicates that the anode temperature is in an abnormal state, and the second temperature detection result indicates that the cathode temperature is in a normal state, whether the cathode temperature is within a preset temperature range is judged, and if so, the battery module is controlled to continue to supply power; if not, controlling the battery module to stop supplying power;
if the target device is in a working state currently, the first temperature detection result is that the anode temperature is in a normal state, and the second temperature detection result is that the cathode temperature is in an abnormal state, judging whether the anode temperature is in a preset temperature range, and if so, controlling the battery module to continue to supply power; and if not, controlling the battery module to stop supplying power.
Specifically, if a temperature sensor of one electrode of a battery plug fails to normally acquire the temperature of the electrode due to a fault, the control method needs to be specifically determined according to the current operating state of the device: if the current equipment is in a starting state, the battery module can be directly controlled to stop supplying power, and a temperature sensor of which the plug does not detect the temperature is detected to be at one pole is detected and replaced after the equipment is shut down; if the current equipment is in a working state, because the normal work of the equipment is not directly influenced by the fault of the temperature sensor, whether the temperature detected by the other pole is within a preset normal temperature range can be judged, if the temperature range of the normal work is met, the temperature of the battery plug is considered to be normal, and the battery module can be controlled to continue to supply power until the equipment finishes the work; and if the temperature of the other electrode does not meet the temperature range of normal operation, determining that the battery plug has a fault to influence the normal operation of the equipment, and controlling the battery module to stop supplying power.
It can be seen that, the redundant design that adopts two way temperature detection in this application embodiment can avoid the misjudgment problem that the sensor damages and causes, when temperature sensor goes wrong all the way, if another way temperature sensor satisfies normal service condition, then the battery also can be normal for the consumer supplies power, guarantees can not because the damage of single sensor and the problem of misjudgment.
It should be noted that, in the embodiment of the present application, the battery module is controlled to stop supplying power, and a manner of controlling the battery module to stop supplying power needs to be determined according to the current operating state of the device, specifically: if the equipment is in a starting state at present, controlling the battery module to stop supplying power immediately; and if the equipment is in a working state at present, controlling the battery module to stop supplying power after a preset time period.
It can be understood that if a temperature sensor fault or battery plug temperature abnormality is detected during startup, the battery module can be controlled to stop supplying power immediately, and the device is shut down; if equipment is in operating condition at present, battery module stops the power supply immediately and probably causes the harm to equipment, can control battery module and stop the power supply after the predetermined time quantum, for example, unmanned aerial vehicle flight in-process, if battery module directly stops the power supply can lead to unmanned aerial vehicle crash, consequently can instruct unmanned aerial vehicle to compel to land, battery module stops the power supply after unmanned aerial vehicle lands.
In an optional embodiment of the present application, the device control method is applied to an unmanned aerial vehicle, and the structure of the device control method is shown in fig. 4, where the positive and negative electrodes of a battery are correspondingly connected with the positive and negative electrodes of a battery plug, after a load in the unmanned aerial vehicle is connected, an MCU (Micro Controller Unit, single chip microcomputer) in a control board collects the temperatures of the positive and negative electrodes of the battery plug through two temperature sensors at the battery plug, determines a protection control strategy of the device according to a temperature detection result, and then controls a switch to turn on or off the battery output by using an NMOS (N-channel Metal Oxide Semiconductor, field effect transistor), so as to perform corresponding monitoring and protection.
Specifically, the control mode after the temperature detection to unmanned aerial vehicle in flight process or in the process of starting up is different:
in the flying process, if only one pole temperature is not detected and the other pole temperature is in a normal range, one pole temperature sensor can be considered to be damaged to a certain extent, but the work of the unmanned aerial vehicle is not influenced, so that the battery can normally supply power to the unmanned aerial vehicle; when the temperature of the two poles is detected abnormally and cannot be detected, the two pole temperature sensors can be judged to be damaged possibly, and the battery prompts that the unmanned aerial vehicle needs to be forced to land; when detecting whether the difference in temperature of two poles of the earth temperature is too big, if the difference in temperature then judge the plug normal, the battery can normally give unmanned aerial vehicle power supply, and it is unusual to indicate one of them utmost point plug to exist when the difference in temperature is too big, and the battery will indicate that unmanned aerial vehicle needs compel to land.
In the starting process, as long as one pole temperature cannot be detected, namely the temperature sensor of the pole is abnormal, the starting process is not carried out; when the temperature detected by the two-pole temperature sensor is lower than a normal temperature range, judging which pole temperature is lower than the normal temperature range, sending warning information to the unmanned aerial vehicle by the battery so as to prompt a user which pole temperature is low at an application end, and automatically shutting down the battery; when the temperatures of the two electrodes are low, prompting a user that the temperatures of the two electrodes are low and the power-off is carried out, and not carrying out the power-on processing; when the temperature detected by the two-pole temperature sensor is higher than the interval, the operation is the same; when the temperatures detected by the two-pole temperature sensors are in a safe temperature range [ T1, T2], damage detection is carried out on a battery plug, whether the temperature difference of the two-pole temperature is too large is judged firstly, if the temperature difference is large, the pole with the higher temperature is found out, and the battery sends warning information to the unmanned aerial vehicle so as to prompt a user that the pole is damaged or broken at an application end and does not carry out starting processing; the startup processing is performed only when the temperature difference is not large and all conditions are satisfied.
Taking the process of the flight protection control of the unmanned aerial vehicle as an example, as shown in fig. 5, the specific flow of the process is as follows:
during flight work, the temperature of the positive pole and the negative pole of the battery plug is continuously detected, and whether the temperatures of the two poles are all normally detected is judged:
if the temperature of the two electrodes can be normally detected, judging whether the temperature of the two electrodes is in a normal range:
if the temperatures of the two electrodes are not in the normal range, prompting the unmanned aerial vehicle that the temperature is abnormal and indicating that the unmanned aerial vehicle is forced to land;
if the temperature of the two poles is in the normal range, whether the temperature difference between the positive pole and the negative pole is too large or not is continuously judged: if the temperature difference is too large, prompting temperature abnormity to the unmanned aerial vehicle and indicating the forced landing of the unmanned aerial vehicle; if the temperature difference is normal, indicating the unmanned aerial vehicle to continue normal work;
if the temperatures of the two poles cannot be normally detected, prompting that the detection of the two poles is abnormal to the unmanned aerial vehicle, and indicating that the unmanned aerial vehicle is forced to land;
if one electrode temperature is not detected normally, judging which electrode is abnormal and cannot be detected:
if the anode temperature is abnormal, judging whether the cathode temperature is in a normal range: if so, the positive temperature sensor is considered to be possibly damaged to a certain extent, the temperature cannot be detected, but the flight of the unmanned aerial vehicle is not influenced, and at the moment, the positive detection abnormity is prompted to the unmanned aerial vehicle, and the unmanned aerial vehicle is instructed to continue to work normally; if not, prompting the unmanned aerial vehicle that the anode detection is abnormal and the cathode temperature is abnormal, and indicating the forced landing of the unmanned aerial vehicle;
if the cathode temperature is abnormal, judging whether the anode temperature is in a normal range: if so, prompting the negative pole detection abnormity to the unmanned aerial vehicle, and indicating the unmanned aerial vehicle to continue working normally; if not, then to unmanned aerial vehicle suggestion negative pole detection abnormity, anodal temperature abnormity, instruct unmanned aerial vehicle to force to land.
Taking the process of starting protection control of the unmanned aerial vehicle as an example, as shown in fig. 6, the specific flow of the process is as follows:
when unmanned aerial vehicle starts, begin to carry out temperature detection to battery plug positive and negative poles, judge whether the equal normal detection of two poles of the earth temperature:
