Detailed Description
The present application is described in further detail below with reference to fig. 1 to 4.
The embodiment of the application provides a temperature control method of smart home equipment, which is applied to a processor for controlling a heating pad to work, and is shown in fig. 1, and the method comprises the following steps:
and S100, acquiring a starting signal.
The starting signals include two types, one type does not include a temperature regulating instruction and an equipment address, and the other type includes a temperature regulating instruction and an equipment address.
Wherein the former start signal is automatically generated by the processor according to a change of a detection signal of the pressure sensor provided in the heating mat. And the other starting signal is generated by an external intelligent terminal under the manual operation and is transmitted to the processor.
S200, judging whether the starting signal contains a temperature adjusting instruction.
Judging whether the starting signal contains a temperature regulating instruction is to distinguish which starting signal is currently obtained, and carrying out temperature control in different modes according to different starting signals.
S300, if the starting signal contains a temperature adjusting instruction, determining a temperature range according to the temperature adjusting instruction, starting the heating pad and controlling the temperature of the heating pad to be maintained in the temperature range.
The temperature adjusting instruction is an accurate temperature control instruction generated by manual selection, is similar to a temperature adjusting instruction sent by an air conditioner remote controller, and can accurately specify the temperature of the heating pad to be about a specific temperature according to the temperature adjusting instruction.
The temperature range is a range value subjected to error correction. For example, the tempering instruction requires a temperature of 26 degrees celsius, and the resulting temperature range is between 25.5 degrees celsius and 26.5 degrees celsius.
If the start signal contains a temperature adjustment instruction, the processor enters a direct adjustment mode.
In the direct adjustment mode, the processor determines the temperature range directly from the attemperation command.
And the way that the processor controls the temperature of the heating pad to be maintained in the temperature range is maintained by a way of feedback adjustment through the temperature signal detected by the temperature sensor.
S400, if the starting signal does not contain the temperature adjusting instruction, acquiring the environmental parameters, determining the temperature range according to the environmental parameters, starting the heating pad and controlling the temperature of the heating pad to be maintained in the temperature range.
The environmental parameters comprise temperature, humidity and other parameters, and are acquired by sensing equipment such as a temperature sensor, a humidity sensor and the like. Different environmental parameters correspond to different preset temperature ranges. The lower the temperature in the environmental parameter, the higher the preset temperature range, the higher the humidity in the environmental parameter, the higher the preset temperature range.
And if the current processor establishes a networking relationship with an external intelligent terminal and an intelligent air conditioner, the intelligent terminal can be used for controlling the air conditioner to synchronously operate, so that the change of the indoor temperature is accelerated.
In one embodiment, determining the temperature range from the environmental parameter comprises the steps of:
and S410, acquiring pressure information, and forming screening data according to the pressure information and the current environmental parameters.
And S420, matching the historical data consistent with the screening data from the historical database, and counting the number of the matched historical data.
The historical database is used for storing historical data and historical temperatures corresponding to the historical data one by one.
The historical data refers to environmental parameters and pressure information recorded during the historical operation of the heating mat.
The historical temperature refers to the temperature that the heating mat maintains for a long time under the corresponding historical data.
Storing historical data and historical temperatures in the historical database corresponds to storing user preference data for reference in determining temperature ranges at the present time.
When the historical data is matched, certain deviation of the data is allowed, for example, the pressure value represented by the pressure information is different by 0.2Kg, and the pressure information is also considered to be consistent.
The data in the historical database is kept for at most one month, and is automatically deleted when the storage time of the data is expired. And in the working process of the heating pad, if the temperature of the heating pad does not change within the preset time, the processor takes the current temperature of the heating pad as the historical temperature, and takes the current environmental parameter and the current pressure information as historical data corresponding to the historical temperature, and stores the historical data and the historical data into a historical database. The preset time is half an hour.
And S430, judging whether the number of the matched historical data is zero or not.
Therefore, whether the number of the matched historical data is zero or not can be determined to be the use condition.
And S440, if the number of the matched historical data is zero, determining a temperature range according to the current environmental parameters.
When the heating pad is just used, is not used for a long time and is changed by a user who uses the heating pad for a long time, the number of the matched historical data is zero, and under the condition that the historical temperature is not used as a reference, the corresponding preset temperature range can be matched only through the current environmental parameters, and the preset temperature range is used as the temperature range which needs to be maintained by the current heating pad. The processor at this time also belongs to the direct mode of throttling.
And S450, if the number of the matched historical data is not zero, determining the current temperature range according to the historical temperature corresponding to the matched historical data.
When the number of the matched historical data is not zero, the historical temperature can be used as a reference, so that the determined temperature range can better meet the actual requirements of the user.
In one embodiment, if the number of the matched historical data is not zero, determining the current temperature range according to the historical temperature corresponding to the matched historical data, including the following steps:
s451, whether the number of the matched historical data is multiple or not is judged.
And S452, if the number of the matched historical data is unique, determining the current temperature range according to the historical temperature corresponding to the matched historical data.
If the number of the matched historical data is unique and other interference items are absent, the current temperature range is determined directly according to the historical temperature corresponding to the matched historical data.
And S453, if the number of the matched historical data is multiple, acquiring the actual time period of the current time, matching the historical data with the historical time period identical to the actual time period, and determining the current temperature range of the historical temperature corresponding to the secondary matched historical data.
When there are a plurality of pieces of matched historical data, it is possible that two persons with similar weights use the heating mat respectively, or that the same user uses the heating mat for a plurality of times at different time intervals. In either case, in order to make the adjusted temperature of the heating pad more suitable for the user's needs, other parameters are also needed to identify the current situation. Thus also requiring the use of historical time to historical data.
Historical time refers to the time when the processor stores historical data in the historical database. Of course, the complete historical time includes the month, the date and the specific time, but only the specific time is used in the step.
A time period is determined from the historical time, which is considered to be a time period during which the user prefers to use the heating pad.
And when the history data of which the history time period is the same as the actual time period is matched, considering that the prior preference of the current user is maintained, and selecting to use the heating pad in the current time period. Therefore, the current temperature range is determined according to the history temperature corresponding to the history data matched again.
The actual time period of the current time is obtained and the history data of which the history time period is the same as the actual time period is matched, except for the case that exactly one history data of which the history time period is the same as the actual time period is matched in step S453, there may be two cases that "there is no history data of which the history time period is the same as the actual time period is matched" and "there are a plurality of history data of which the time period of which the history time period is the same as the time period of which the current time is matched". According to the matching result, different steps are required to be executed.
In one embodiment, if there is no history data matching the history time period with the same actual time period, selecting the history data with the history time period earlier than the actual time period and closest to the actual time period and the history data with the history time period later than the actual time period and closest to the actual time period, determining the average temperature according to the history temperatures corresponding to the two selected history data, and determining the current temperature range according to the average temperature.
If there is no history data matching the history time period in which the history data is the same as the actual time period, which indicates that the user does not use the heating pad currently in the near future, reference can be made only from the history temperature corresponding to the similar history data, and the average temperature is obtained by selecting two history temperatures, one large history temperature and one small history temperature, so as to reduce the occurrence of errors. At which point the processor enters an average adjustment mode.
The history data closest to the actual time period is required to be closer to the actual time period than other history data, and the interval between the history data and the actual time period is smaller than a preset interval, which is 1 hour in the present embodiment.
Therefore, if there is no historical data with a corresponding historical time period earlier than the actual time period and closest to the actual time period, or there is no historical data with a corresponding historical time period later than the actual time period and closest to the actual time period, or even if both of the historical data exist but are separated from the actual time period by a longer time period, the current environmental parameters are directly adopted to determine the temperature range, so that obvious errors are reduced.
After determining the current temperature range according to the average temperature, the method further comprises the following steps:
and S461, judging whether a starting signal containing a temperature adjusting instruction is received.
It is determined whether the activation signal containing the temperature adjustment command is received, which is actually whether the user is satisfied with the amount of heat generated by the current heater at the average temperature.
And S462, if the starting signal containing the temperature adjusting instruction is not received, maintaining the temperature of the corresponding heating mat within the temperature range corresponding to the average temperature.
If the start signal containing the temperature adjusting instruction is not received, the current temperature of the user is satisfied, and therefore, the temperature of the heating mat does not need to be changed.
S463, if the start signal including the temperature adjustment command is received, it is determined whether the temperature adjustment command is the down temperature command or the up temperature command.
If the starting signal containing the temperature adjusting instruction is received, the user is indicated to be dissatisfied with the current temperature. At this time, the temperature is not adjusted to the corresponding specific temperature directly according to the temperature adjustment instruction, but the temperature corresponding to the temperature adjustment instruction is judged to be increased or decreased relative to the average temperature.
If the temperature corresponding to the temperature regulation instruction is increased relative to the average temperature, the temperature regulation instruction is regarded as an up-regulation temperature instruction; otherwise, the temperature regulating instruction is considered as the down temperature regulating instruction.
And S464, if the temperature adjusting instruction is a temperature adjusting instruction, selecting a historical temperature with lower temperature from the historical temperatures corresponding to the two selected historical data to determine a new temperature range, and controlling the temperature of the heating pad to be in the new temperature range.
And S465, if the temperature adjusting instruction is an upward temperature adjusting instruction, selecting a historical temperature with higher temperature from the historical temperatures corresponding to the two selected historical data to determine a new temperature range, and controlling the temperature of the heating pad to be in the new temperature range.
Only when the processor is in the average adjustment mode, the up-temperature instruction selects a historical temperature with a higher temperature to determine a new temperature range, and the down-temperature instruction selects a historical temperature with a lower temperature to determine a new temperature range. And as long as the processor completes one-time temperature adjustment aiming at the temperature up-regulation instruction or the temperature down-regulation instruction, the processor exits the average regulation mode and enters the direct regulation mode.
In one embodiment, if a plurality of history data are matched, wherein the time interval of the history data is the same as the time interval of the current time, the history temperatures corresponding to the matched history data are sorted from small to large to form a temperature set, the history temperature sorted as N in the temperature set is selected to determine a temperature range, and N is 1 in an initial state.
And if a plurality of pieces of history data with the same time interval of the history time and the same time interval of the current time are matched, the processor enters a step-by-step adjusting mode.
In the gear-by-gear adjusting mode, the processor sorts the matched historical temperatures. The ranking is in a small to large manner, i.e. the first historical temperature is the lowest and the values of the historical temperatures after ranking are higher. In the initial state, the processor selects the historical temperature with the lowest temperature to determine the temperature range.
After the historical temperatures ranked as N in the temperature set are selected to determine the temperature range, the method further comprises the following steps:
and S471, judging whether a starting signal containing a temperature adjusting instruction is received.
S472, if the start signal including the temperature adjustment instruction is not received, maintaining the temperature of the corresponding heating mat within the current temperature range.
S473, if the starting signal containing the temperature adjusting instruction is received, whether the temperature adjusting instruction is a temperature down-adjusting instruction or a temperature up-adjusting instruction is judged.
And S474, if the temperature adjusting instruction is a temperature down-adjusting instruction, determining a new temperature range according to the temperature down-adjusting instruction, and controlling the temperature of the heating pad to be in the new temperature range.
Because the historical temperature selected by the processor at the beginning is the lowest in the gear-by-gear adjusting mode, if the user still wants to adjust the temperature downwards, the historical temperatures in the temperature set do not belong to the requirements of the current user, and then the processor exits the gear-by-gear adjusting mode and enters the direct adjusting mode to directly determine a new temperature range through the temperature adjusting instruction.
And S475, if the temperature adjusting instruction is an upward temperature adjusting instruction, N = N +1, and whether N is greater than M is judged, wherein M is the number of the historical temperatures in the data set.
And S476, if N is larger than M, determining a new temperature range by the temperature adjusting command.
If the processor attempts to adjust all of the historical temperatures in the temperature set and the user still issues an up temperature command, the processor exits the step-by-step adjustment mode and enters the direct adjustment mode.
S477, if N is less than or equal to M, determining a new temperature range by the historical temperature ranked as N again.
And if the historical temperatures in the temperature set are not traversed, the processor determines a new temperature range again by the historical temperatures which are sorted into N.
In one embodiment, there are a plurality of heating pads and a plurality of corresponding processors, and if a certain heating pad is controlled to operate by the activation signal sent by the intelligent terminal, information with identification needs to be added to the activation signal. Therefore, the start signal provided by the intelligent terminal includes a designated device address, and each processor stores a preset device address. The preset device addresses of different processors are different.
After the starting signal is acquired, the method further comprises the following steps:
and S110, judging whether the specified device address is consistent with the preset device address.
And S120, if the specified equipment address is consistent with the preset equipment address, the starting signal is considered to contain a temperature regulating instruction.
And S130, if the specified equipment address is inconsistent with the preset equipment address, not acting.
The precondition for determining whether the specified device address is consistent with the preset device address is that the start signal includes the specified device address, and if the start signal is generated by the processor, the start signal does not include the specified device address, so before determining whether the specified device address is consistent with the preset device address, it is determined whether the start signal includes the specified device address, and if the start signal does not include the specified device address, the step S400 is directly skipped. If the starting signal contains the appointed equipment address, the current judgment is executed.
Similarly, if the specified device address is consistent with the preset device address, the start signal is necessarily provided by the intelligent terminal, that is, the current start signal includes the temperature adjustment instruction, and then step S300 is executed.
A temperature control system of smart home equipment is shown in figure 2 and comprises main equipment and sub-equipment.
The main equipment comprises a processor, a pressure sensor, an instruction distribution module, a Bluetooth communication module and a local area network radio frequency transceiving module; the sub-equipment comprises a processor, a pressure sensor and a local area network radio frequency transceiving module.
And the Bluetooth communication module is used for establishing Bluetooth connection with an external intelligent terminal and receiving a starting signal which is transmitted by the intelligent terminal and contains a temperature adjusting instruction and an appointed equipment address.
And the pressure sensor is used for detecting the pressure on the heating pad and outputting a pressure signal.
And the local area network radio frequency receiving and transmitting module is used for carrying out data transmission between the main equipment and the sub-equipment of the distribution network through radio frequency.
And the instruction distribution module is used for transmitting the starting signal by the Bluetooth communication module and distributing the starting signal to the corresponding main equipment or the corresponding sub-equipment according to the specified equipment address in the starting signal.
The main equipment and the sub-equipment are respectively arranged on different heating pads, and the number of the sub-equipment connected with the same main equipment is multiple.
And the processor is used for receiving the pressure signal of the corresponding pressure sensor, generating a corresponding starting signal which does not contain a temperature regulating instruction according to whether the pressure signal is suddenly changed or not, and receiving the starting signal which is transmitted by the local area network radio frequency transceiver module and contains the temperature regulating instruction and the address of the specified equipment.
And judging whether the pressure signal is suddenly changed, namely subtracting the pressure value represented by the historical pressure signal from the pressure value represented by the currently detected pressure signal to obtain a difference value, and judging whether the difference value is greater than a preset upper limit threshold value. If the difference value is larger than a preset upper limit threshold value, the pressure signal is considered to be a sudden change; conversely, the pressure signal is considered to be unmutated. The historical pressure signal is a historical pressure signal stored in the processor, and is periodically updated by the memory at 1 second 1 time intervals. The preset threshold is a number representing the average weight of a 7 year old child.
In addition, no matter which start signal is obtained, if the pressure signal output by the pressure sensor suddenly and sharply drops after the heating mat starts to operate, the countdown for 5 minutes is started, and after the timing is finished, the pressure signal does not rise, and the processor turns off the heating of the heating mat. In order to quantify the sudden and violent drop of the pressure signal, when the heating pad is heated, the processor can continuously update the historical pressure signal, subtract the pressure value represented by the historical pressure signal from the pressure value represented by the currently detected pressure signal to obtain a difference value, judge whether the difference value is smaller than a preset lower limit threshold value, and if the difference value is smaller than the preset lower limit threshold value, consider that the pressure signal has a downward sudden change. The preset lower threshold is a negative number.
And the processor is also used for storing and executing the computer program of the temperature control method of the intelligent household equipment.
Since the pressure sensors and the processors are in a one-to-one correspondence relationship, the activation signal generated by the pressure sensor must be processed by the corresponding processor. The activation signal generated from the pressure signal does not contain a device address.
The start signal provided by the intelligent terminal needs to be transmitted to the main device first, and in order to enable the main device to clearly transmit the start signal to which sub-device or to control the heating mat corresponding to the main device, the device address corresponding to the heating mat to be controlled needs to be added to the start signal.
In addition to the above-mentioned generation of the start signal by the pressure signal and the provision of the start signal by the intelligent terminal, the main device or the sub-device also has a function of directly generating the start signal by manual interaction to control the temperature of the heating mat.
Specifically, the main device and the sub-devices are respectively provided with a human-computer interaction interface, the human-computer interaction interface comprises a key and a status indicator light, and the key and the status indicator light are respectively connected with the corresponding processors.
The temperature adjustment of the heating pad controlled by the key is relatively limited, and in this embodiment, the key corresponds to the temperatures of the three-level heating pad, which are high, medium and low, respectively.
No matter the equipment is main equipment or sub-equipment, when the equipment is operated, the gear shifting is carried out by pressing the key for a short time, and the gear circulating sequence triggered by pressing the key for a short time each time is as follows: high- > medium- > low- > high.
In addition, under the equipment running state, press the button for 1.5 seconds for a long time, equipment enters standby state, and the suggestion of status indicator lamp: blue- > purple- > red- > blue- > purple- > red (each lamp is bright for 400ms) and then enters a standby mode.
Under standby state, press the button for a long time for 1.5 seconds, enter the start state, the suggestion of status indicator lamp: blue- > purple- > red- > blue- > purple- > red (each lamp is lightened for 400ms) and then automatically enters a high gear to control the heating of the heating pad.
Referring to fig. 3, fig. 3 is a networking system of smart home devices.
The networking comprises main equipment, sub-equipment, an intelligent terminal and a server. The main device and the sub-devices establish a local area network through wireless radio frequency, the main device and the intelligent terminal establish wireless communication through Bluetooth, and the intelligent device and the server establish a data transmission channel through the Internet.
The server has the functions of authority management of the intelligent terminal, personnel account management, equipment state information statistics and the like.
The Bluetooth communication between the main equipment and the external intelligent terminal is established in the following mode:
