Taking an intelligent door lock with a touch panel as an example, fig. 1 is a schematic structural diagram of an existing intelligent door lock according to an exemplary embodiment of the present application, where the intelligent door lock in fig. 1 includes a touch panel (including 12 keys), a main control module, and a touch module. The touch module comprises a switch matrix, each key on the touch panel is correspondingly provided with a key switch in the switch matrix, and the touch module polls and controls each key on the scanning touch panel through the switch matrix. In order to ensure that the user presses the keys to respond in time, the touch module needs to constantly poll and scan each key through the switch matrix, so that the power consumption of the touch module is always higher in a standby state.
The inventors estimated battery replacement time for various intelligent door locks on the market according to the standby power consumption, as shown in table 1, which is an exemplary battery usage time of the intelligent door lock. As can be seen from table 1, the standby power consumption current of various intelligent door locks on the market at present is above 50uA, and the primary battery needs to be replaced within one year. Therefore, the intelligent door lock has relatively high power consumption and short battery life because of relatively high current consumption in the standby state.
| Door lock category | A | B | C | D | E |
| Standby power consumption | 121.6uA | 52.6uA | 76.3uA | 58.9uA | 121.8uA |
| Battery life time | 9.6 months | 13 months of | 12 months of | 11.1 month | 8.5 months |
TABLE 1
Based on the above, the application uses all keys on the touch panel as one key by connecting all keys on the touch panel in series, so that the intelligent door lock can detect whether a touch operation for touching the keys is executed or not by scanning one key in a standby state, and when the touch operation is detected, each key is scanned respectively to determine the key which is executed the touch operation. Because the intelligent door lock only needs to scan one key instead of all keys in the standby state, the current consumption in the standby state can be reduced, thereby reducing the standby power consumption and prolonging the service life of the battery.
It will be appreciated by those skilled in the art that the intelligent control device according to the present application refers to a device with a touch panel including keys, and is not limited to the above-mentioned intelligent door lock with a touch panel. The application is illustrated in more detail below by means of specific examples:
fig. 2 is a schematic structural diagram of an intelligent control device according to an exemplary embodiment of the present application, and as shown in fig. 2, the intelligent control device includes: the touch panel comprises a scanning control circuit and a touch panel (12 keys are listed in fig. 2) comprising a plurality of keys, and all the keys on the touch panel are connected to the scanning control circuit in series. Wherein, the touch panel is used for detecting the touch operation executed for touching the key; and the scanning control circuit is used for controlling to scan the keys on the touch panel to determine the keys which are subjected to the touch operation when the touch operation for touching the keys is detected by the touch panel, and controlling to stop scanning the keys on the touch panel when the received information of the keys which are subjected to the touch operation and determined by scanning meets the preset condition.
The mode of detecting the touch operation by the scanning control circuit is determined by the attribute of the touch panel, and if the touch panel is a capacitive touch panel, the scanning control circuit can detect the touch operation by detecting the change of the capacitance value. The scan control circuit may poll each key on the scan touch panel through the switch matrix (each key has a corresponding key switch in the switch matrix).
It will be understood by those skilled in the art that all the keys on the touch panel are connected in series to the scan control circuit, and the adopted serial connection mode may be parallel serial connection or serial connection, and the parallel serial connection mode is illustrated in fig. 2, but the serial connection mode is not limited by the present application.
In one example, for controlling to stop a process of scanning a key on a touch panel when information of the key on which a touch operation is performed, which is determined by scanning, is received to meet a preset condition, the preset condition may include two cases, the first is: when the number of the received information of the keys which are determined by scanning and are subjected to touch operation is a preset number, controlling to stop scanning the keys on the touch panel; the second is: and when the information of the key which is determined by scanning and is subjected to touch operation is preset key information, controlling to stop scanning the key on the touch panel.
The preset number refers to preset key digits to be input. The preset key information may be a key value of a key, and a flag for indicating that the user has completed key password input may be set as the preset key information, for example, "×" or "#", as an end flag.
Taking intelligent control equipment as an intelligent door lock, as shown in fig. 2, for example, 12 keys are arranged on a touch panel of the intelligent door lock, a switch matrix for scanning the 12 keys is correspondingly arranged in a scanning control circuit, under a standby state of the intelligent door lock, according to the existing key scanning control mode, the scanning control circuit needs to continuously control the opening and closing of each corresponding key switch in the switch matrix so as to scan the 12 keys in a polling manner, and according to the key scanning control mode of the application, the method is equivalent to only scanning one key, the control operation is not required to be performed on the switch matrix, namely, the switch matrix is in a closing state, only when the touch operation is detected, the switch matrix is opened, and the opening and closing of each corresponding key switch in the switch matrix are controlled so as to scan the 12 keys in a polling manner. Therefore, the power consumption of the intelligent door lock is theoretically 1/12 times that of the existing intelligent door lock in the standby state. Through tests, the current consumption of the intelligent door lock in the standby state is between 20uA and 25uA, which is reduced by one time compared with the current consumption in the prior art, and the actual power consumption in the standby state is at least 1/2 times of the current consumption in the prior art by considering the influence of factors such as leakage current, standby current and the like of a chip in the intelligent door lock.
It should be noted that, the intelligent control device may further include a power supply module, a disable module, and the like, in addition to the touch panel and the scan control circuit.
In this embodiment, since all the keys included in the touch panel on the intelligent control device are connected in series to the scan control circuit, the scan control circuit may further control the keys on the scan touch panel to determine the keys to be touched when detecting that the touch panel is touched by the touch keys, and control to stop scanning the keys on the touch panel when the received information of the keys to be touched determined by the scan meets the preset condition. As can be seen from the above description, in the standby state, the intelligent control device does not need to continuously scan each key on the touch panel, enters the working state only when the touch operation of the touch panel for touching the key is detected, starts scanning each key on the touch panel, and immediately stops the scanning operation when the received information of the key determined by the scanning to be touched meets the preset condition.
In an embodiment, fig. 3 is a schematic structural diagram of another intelligent control device according to the embodiment shown in fig. 2, and as shown in fig. 3, the scan control circuit may include a main control module and a touch control module, where the main control module is connected with the touch control module, and all keys on the touch control panel are connected in series to the touch control module. The touch control module is used for sending a touch notification message to the main control module when detecting that the touch control panel is executed for touching keys; the main control module is used for controlling the scanning of the keys on the touch panel to determine the keys which are subjected to touch operation, and controlling to stop scanning of the keys on the touch panel when the received information of the keys which are subjected to touch operation determined by scanning meets the preset condition. The touch control module and the main control module can be connected through an I2C bus, and touch notification information is sent to the main control module in an interrupt mode.
In one example, during the real-time detection of the touch operation performed by the touch panel for touching the keys, the intelligent control device may be in a standby state all the time, i.e. the main control module is in a sleep mode, and when the main control module receives the touch notification message sent by the touch control module, the intelligent control device enters a working state from the standby state, i.e. the main control module switches from the sleep mode to the wake mode, and starts to control the keys on the touch panel to be scanned.
In another example, for each key process of the main control module on the control scanning touch panel, in order to ensure that the key can respond in time when pressed, the scanning interval duration, that is, the duration of each time the scanning is completed, may be preset according to practical experience, where the time taken from the touch detection operation to the sending of the touch notification message to the main control module by the touch control module is very short and negligible, but the set scanning interval duration cannot be less than the time required for completing one time of scanning. For a touch panel on an intelligent door lock, the touch panel generally comprises 12 keys (numbers 0-9, #), the time for scanning one key is about 5 ms, the time required for completing one scan is 60 ms, and the time for pressing the key by a user is about 100 ms, so that one scan can ensure that the key is pressed to respond timely, and the set scanning interval time is required to be greater than 60 ms and less than 200 ms for continuously pressing the key by the user, for example, the scanning interval time can be set to be 150 ms.
It should be noted that, if the main control module does not receive the scanning result within the preset time, it indicates that the user has not input the complete key password, and the key password input has ended, the main control module may directly control to stop scanning the key on the touch panel, and prompt the user to re-input the key password in a voice manner or a screen reminding manner.
In an embodiment, fig. 4 is a schematic diagram of a connection structure between a touch module and each key shown in the embodiment of fig. 3, where, as shown in fig. 4, the touch module is further separately connected to each key on the touch panel, that is, each key on the touch panel is separately connected to the touch module through a connector, so that the main control module may scan each key on the touch panel by controlling the touch module, that is, the main control module may include: the sending unit is used for sending a scanning instruction to the touch module so that the touch module scans each key on the touch panel; and the receiving unit is used for receiving the information of the key which is determined to be subjected to the touch operation by scanning and transmitted by the touch control module. Compared with the existing intelligent control equipment, the intelligent control equipment in the embodiment can achieve the purpose of reducing standby power consumption without adding any hardware chip, so that the implementation cost is low.
For the 12 keys shown in fig. 2, the touch module may be composed of a touch chip with 13 scan channels, where the 12 keys are connected to 1 scan channel in series for detecting the touch operation performed for touching the keys, and the other 12 scan channels are respectively connected to each key on the touch panel for respectively scanning each key to determine the key on which the touch operation is performed.
Based on the intelligent control device shown in fig. 4, the process of stopping scanning the keys on the touch panel is controlled when the main control module cannot receive the information of the keys which are determined by scanning and are touched within the preset time, the main control module can send a stopping instruction to the touch module, and the touch module stops scanning the keys on the touch panel after receiving the stopping instruction.
In an exemplary scenario, for 12 keys included in the touch panel of the smart door lock, the connector needs to be connected to the 12 keys respectively to connect the 12 keys to the touch module respectively, and besides, the touch module is further connected to the 12 keys connected in series, so that the touch module has 13 channels, wherein 1 channel is used for detecting touch operations, and the other 12 channels are used for scanning the 12 keys.
In another embodiment, as shown in fig. 5, a schematic diagram of a connection structure between a first type touch module and a second type touch module and each key according to the embodiment shown in fig. 3 of the present application is shown, where the touch module in fig. 5 may be a first type touch module provided by an intelligent control device and used for detecting that a touch panel is executed to touch the key, the intelligent control device further includes a second type touch module connected to the main control module, and the second type touch module is further separately connected to each key on the touch panel and used for scanning each key on the touch panel. Thus, the main control module may include: the sending unit is used for sending a scanning instruction to the second type of touch module so that the second type of touch module scans each key on the touch panel; the receiving unit is used for receiving the information of the keys which are determined to be touched and operated by scanning and sent by the second type of touch control module.
The first type touch control module and the second type touch control module can be connected with the main control module through the I2C bus. The first type of touch module may be a low-power-consumption single-path touch module, i.e. may be composed of a touch chip having a single-path scanning channel. The second type of touch module may be a touch module used in the prior art, and for the 12 keys shown in fig. 2, the second type of touch module may be a touch chip with 12 scan channels, where the 12 scan channels are respectively connected to each key on the touch panel, and are used to scan each key respectively to determine the key on which the touch operation is performed.
In the intelligent control device in this embodiment, in a working state, each key on the touch panel is scanned by the second type touch module, and in a standby state, touch operation is detected by the first type touch module, and since the first type touch module only needs to process touch operation of one channel, the processing core of the first type touch module is simple compared with the processing core of the second type touch module, and the operation capability is strong and the time is short.
Based on the intelligent control device shown in fig. 5, the second type touch module may be in a sleep mode in a standby state, and when a scan command is received, the sleep mode is switched to an awake mode, and each key on the touch panel starts to be scanned.
In yet another embodiment, the touch module may include: a stop detection control unit for stopping detecting that the touch panel is being executed for touching the key after sending the touch notification message to the main control module; the main control module can also include: and the touch module control unit is used for controlling the touch module to start detecting the touch operation of the touch panel for touching the keys after controlling to stop scanning the keys on the touch panel. Because the touch control module stops detecting after detecting the touch operation and starts detecting the touch operation after the scanning is finished, the power consumption of the intelligent control device can be further reduced.
In still another embodiment, the main control module may further include a verification unit, configured to, after the control unit stops scanning the keys on the touch panel, sort the received information of the keys that are executed with the touch operation according to the receiving time from small to large to obtain a key sequence, and then query a database by using the key sequence, where a correspondence between the key sequence and the operation instruction is recorded, and if the key sequence is queried, execute the operation instruction corresponding to the key sequence.
Based on the above-mentioned intelligent door lock scene, it is assumed that the key sequence obtained by sorting the information of the keys input by the user is 238658, and the corresponding relationship of 238658 and the door lock release instruction is stored in the database, so that the corresponding door lock release instruction can be queried in the database, and after the door lock release instruction is executed, the door is opened, so that the user can enter the room.
