In one embodiment, when the distance between the sensing element 100 and the magnetic element 8 is smaller than the first threshold, it is determined that the target object is in the off state; when the distance between the sensing component 100 and the magnetic component 8 is greater than the second threshold value, the object is judged to be in an on state.

In a further aspect, the gateway 102 may access the internet, thereby enabling data exchange with the intelligent terminal 104 that accesses the internet. The gateway 102 may be a gateway device dedicated to the gateway 102, or may be another device having the gateway 102 function, for example, a speaker device having the gateway function, a display device having the gateway function, a computer having the gateway function, a host, or the like.

The switch state detector 101 in the partial aspects of the embodiments of the present invention will be described in detail below, but the scope of the embodiments of the present invention is not limited thereto.

Based on fig. 1-16, a switch state detector 101 proposed by the present disclosure is specifically explained. Referring to fig. 4 and 15, the switch state detector 101 includes a magnetic component 8 and an induction component 100, where the magnetic component 8 is used to generate a magnetic field; the sensing assembly 100 is arranged independently of the magnetic assembly 8 and is capable of changing position relative to the magnetic assembly 8; and the induction component 100 is used for detecting magnetic induction intensity, as shown in fig. 2, and is configured to: when the distance parameter between the magnetic component 8 and the sensing component 100 is gradually reduced to a first interval taking a first threshold value as an end point, sending a first message to the outside; the first message is used for indicating that a target object associated with the sensing assembly 100 is in an open state; when the distance parameter between the magnetic component 8 and the sensing component 100 is gradually increased to a second interval taking a second threshold value as a starting point, a second message is sent to the outside; the second message is used for indicating that the target object associated with the sensing assembly 100 is in a closed state; the distance parameter is associated with the magnetic induction; the first interval and the second interval are not coincident, and the difference value between the second threshold value and the first threshold value is greater than or equal to 1mm.

The magnetic component 8 is understood to be a component with magnetic properties, which may be a device provided with a permanent magnet or an electro-magnetic generator, which is capable of generating a stable magnetic field. The sensing component 100 and the magnetic component 8 are respectively disposed on a movable object and a fixed surface matched with the object, and the object can move in response to a manipulation, so that the position between the magnetic component 8 and the sensing component 100 changes, for example, the object can be a movable object such as a door, a window, a drawer, etc. The induction component 100 can sense the change of magnetic induction intensity, when the distance between the magnetic component 8 and the induction component 100 gradually decreases, the magnetic induction intensity sensed by the induction component 100 can gradually increase, when the distance between the magnetic component 8 and the induction component 100 gradually increases, the magnetic induction intensity sensed by the induction component 100 can gradually decrease, and the induction component 100 acquires the distance information between the magnetic component 8 and the induction component 100 by detecting the magnetic induction intensity. The distance parameter may be understood as a distance value between the magnetic assembly 8 and the inductive assembly 100. The first interval ending with the first threshold and the second interval ending with the second threshold are understood as dividing the distance parameter between the magnetic component 8 and the inductive component 100 into at least two intervals, wherein the first interval is from 0 to the first threshold, and the second interval is from the second threshold to infinity. The distance parameter is related to the magnetic induction intensity, which can be understood that when the distance parameter is changed, the magnetic induction intensity sensed by the sensing module is also changed correspondingly, the first threshold and the second threshold can respectively correspond to a magnetic induction intensity, and the sensing assembly 100 determines the "on" and "off" states of the target object by sensing the magnetic induction intensities corresponding to the first threshold and the second threshold.

The existing switch state detector is too small in the distinction of the induction conditions of the two states of "on" and "off", so that when the distance between the magnetic component 8 and the induction component 100 reaches a critical value, the magnetic induction intensity generated by the magnetic component 8 is influenced by the environment and fluctuates, and the magnetic induction module 1 in the induction component 100 detects that the magnetic induction intensity also fluctuates, so that the induction state of the induction component 100 is repeatedly switched between "on" and "off", so that the intelligent device 103 connected with the intelligent device repeatedly switches the working state, and the controlled intelligent device is damaged. The applicant discloses a switch state detector 101, by setting the difference between the first threshold and the second threshold to be greater than or equal to 1mm, so that a hysteresis interval of at least 1mm is provided between the first interval and the second interval, when the distance parameter reaches the hysteresis interval, the sensing state of the sensing component 100 is not changed, and the last sensing state is maintained. When the hysteresis interval which is more than or equal to 1mm is set, the sensing state of the sensing assembly 100 can be effectively prevented from being repeatedly switched when the distance parameter reaches a certain critical value, so that the intelligent device 103 connected with the sensing assembly 100 is protected from being repeatedly switched to the working state. The applicant finds through experiments that when the hysteresis interval is smaller than 1mm, the fluctuation of the magnetic induction intensity sensed by the magnetic induction module 1 may exceed the hysteresis interval, and the repeated switching of the sensing state of the sensing assembly 100 may be caused, so that the hysteresis interval needs to be set to be larger than 1mm, and the stability of the sensing state is ensured. In a specific embodiment, the first threshold is set to 18mm, the second threshold is set to 23mm, and further the first interval is [0, 18] mm, the second interval is [23, ++ infinity ] mm, and the hysteresis interval is [18, 23] mm, and setting a hysteresis interval of 5mm can more effectively improve the stability of the induction state. Of course, it is within the scope of the present embodiment as long as the difference between the first threshold and the second threshold is greater than or equal to 1 mm.

Further, the sensing assembly 100 is further configured to: when the distance parameter changes from the second interval to the first interval in response to the position change between the magnetic component 8 and the sensing component 100, sending a first message to the outside; when the distance parameter changes from the first interval to the second interval in response to the change of the position between the magnetic component 8 and the sensing component 100, a second message is sent to the outside. Because of the existence of the hysteresis section, the situation that the distance parameter enters the first section or the second section from the hysteresis section in response to the position change of the magnetic component 8 and the sensing component 100, at this time, whether the section before entering the hysteresis section is identical to the section after entering the hysteresis section needs to be judged, if so, a message is not sent, if not, a corresponding message is sent, in a specific embodiment, the distance parameter is gradually reduced, the second section enters the first section through the hysteresis section, and the sensing component 100 sends the first message to the outside; in another case, the distance parameter gradually decreases, and enters the hysteresis interval from the second interval and then gradually increases, and returns to the second interval from the hysteresis interval, so that the sensing component 100 does not send a message, and further, the repeated sending of the message can be effectively prevented.

In some embodiments, as shown in fig. 3, the induction assembly 100 includes a magnetic induction module 1 and a wireless transmission module 2, where the magnetic induction module 1 is used to induce magnetic induction and generate a level signal; the wireless transmission module 2 is electrically connected with the magnetic induction module 1 and is configured to: and when the level signal is detected to jump, sending a first message or a second message to the outside. The magnetic induction module 1 adopts a level jump type hall switch or a magnetic switch sensor, that is, a level signal sent by the magnetic induction module 1 jumps according to the change of magnetic induction intensity, and the wireless transmission module 2 can be further provided with other devices or combination of devices for digitally sampling, filtering or logically operating the signal, so that the level signal output by the magnetic induction module 1 can be detected. In a specific embodiment, the wireless transmitting module 2 includes a processing chip, the hall switch is electrically connected to a pin of the processing chip, and the processing chip determines the working state of the magnetic induction module 1 according to the level signal of the pin.

Further, the level signals include a first level signal and a second level signal opposite to the first level signal; when the distance parameter between the induction component 100 and the magnetic component 8 is in the first interval, the magnetic induction module 1 continuously outputs a first level signal; when the distance parameter between the induction component 100 and the magnetic component 8 is in the second interval, the magnetic induction module 1 continuously outputs a second level signal; when the distance parameter enters a second interval from a first interval, the level signal output by the magnetic induction module 1 jumps from a first level signal to a second level signal, and the wireless transmission module 2 sends a second message outwards; when the distance parameter enters the first interval from the second interval, the level signal output by the magnetic induction module 1 jumps from the second level signal to the first level signal, and the wireless transmitting module 2 transmits a first message to the outside. The second level signal is opposite to the first level signal, which is understood as that the first level signal is high level, the second level signal is low level, or the first level signal is low level, and the second level signal is high level. The magnetic induction module 1 adopted in the embodiment is a KTM1901XD type magnetic switch sensor, which is a magnetic switch sensor integrated with a tunnel magnetic resistance technology and a CMOS technology, has the characteristics of high precision, high speed, low power consumption, high sensitivity and the like, and supports the detection of a forward magnetic field and a reverse magnetic field; the magnetic switch sensor outputs a low level when the absolute value of the magnetic field strength is greater than 9Gauss, and outputs a high level when the absolute value of the magnetic field strength is less than 6 Gauss. Namely, for the induction module 100 using the KTM1901XD type magnetic switch sensor, the magnetic induction intensity interval corresponding to the first interval is [9, and the magnetic induction intensity interval corresponding to the second interval is [0,6] Gauss. When the magnetic induction intensity detected by the magnetic switch sensor is increased from the interval of [0,6] Gauss to [9, ++ infinity in the time of the interval, the magnetic switch sensor jumps from the output high level to the output low level; when the magnetic induction intensity detected by the magnetic switch sensor is reduced from the interval of [9, + ] Gauss to the interval of [0,6] Gauss, the magnetic switch sensor jumps from the output low level to the output high level, and the induction component 100 externally sends a corresponding message according to the level jump of the magnetic switch sensor. The beneficial effects are as follows: compared with a magnetic induction module which continuously detects the magnetic field intensity, the magnetic induction module 1 of the embodiment adopts the magnetic switch sensor with the level jump function, and when the magnetic induction intensity reaches the corresponding threshold value, the jump occurs, so that the processing frequency of the processing chip to the electric signal sent by the magnetic induction module 1 can be effectively reduced, and the power consumption is reduced.

Further, the level signals include a first level signal and a second level signal opposite to the first level signal; when the distance parameter between the induction component 100 and the magnetic component 8 is in the first interval, the magnetic induction module 1 continuously outputs a first level signal; when the distance parameter between the induction component 100 and the magnetic component 8 is in the second interval, the magnetic induction module 1 continuously outputs a second level signal; when the distance parameter enters a second interval from the first interval through a third interval, the level signal output by the magnetic induction module 1 jumps to a second level signal, and the wireless transmitting module 2 transmits a second message to the outside; when the distance parameter enters a first interval from a second interval through a third interval, the level signal output by the magnetic induction module 1 jumps to a first level signal, and the wireless transmitting module 2 transmits a first message outwards; the third section is a section greater than the first threshold and less than the second threshold. The third interval is the hysteresis interval described above, and when the distance parameter is in the third interval, the level signal output by the magnetic induction module 1 is not changed, so that the wireless transmission module 2 does not send a message to the outside, so as to prevent the sensing state of the sensing component 100 from repeatedly switching between "on" and "off". Because of the existence of the third section, the situation that the distance parameter enters the first section or the second section from the third section in response to the position change of the magnetic component 8 and the sensing component 100 is generated, at this time, whether the section before entering the third section is the same as the section after leaving the third section is required to be judged, if so, the level output by the magnetic induction module 1 does not jump, if not, the level output by the magnetic induction module 1 jumps, and then the wireless transmission module 2 sends a corresponding message to the outside. The scheme can effectively prevent the wireless transmitting module 2 from sending repeated messages to the outside.

In some embodiments, the induction assembly 100 includes a magnetic induction module 1 and a wireless transmission module 2, wherein the magnetic induction module 1 is used for inducing magnetic induction intensity and generating a voltage signal; the wireless transmitting module 2 is electrically connected with the magnetic induction module 1 to receive the voltage signal, compare the voltage signal with a reference voltage, and then send a first message or a second message according to a comparison result. The magnetic induction module 1 is a hall sensor, which can detect nearby magnetic induction intensity and generate a voltage signal corresponding to the current magnetic induction intensity, and compared with the magnetic switch sensor described above, the hall sensor can output a voltage signal instead of a level signal, and the output voltage signal can be changed in real time according to the change of the magnetic induction intensity. In a specific embodiment, the hall sensor is configured to continuously detect magnetic induction and send a continuous voltage signal, and the wireless transmitting module 2 receives the voltage signal and determines the interval in which the distance parameter is located according to the voltage signal. The magnetic induction module 1 using a hall sensor has the advantage that the first threshold value and the second threshold value can be flexibly changed by adjusting them to any value, i.e. the first interval and the second interval. Since the mounting method of the switch state sensor is mostly adhered to the mounting surface through the double faced adhesive tape 9, the mounting method is one-time mounting, the adjustability is poor, and if the first mounting position is not good, the condition that the sensing effect is poor, the sensing error occurs or the sensing is insensitive can be caused. The magnetic induction module 1 of this embodiment adopts a hall sensor capable of continuously detecting magnetic induction intensity, and a user can adjust the first threshold and the second threshold through the intelligent terminal 104, so as to adjust the switch state detector 101 to a suitable induction distance, and optimize the induction state.

Further, the reference voltage includes a first reference voltage value and a second reference voltage value; the wireless transmission module 2 is configured to: when the voltage signal is gradually reduced to be smaller than or equal to a first reference voltage value, a first message is transmitted; the first reference voltage value characterizes the distance of the inductive component 100 from the magnetic component 8 as a first threshold value; when the voltage signal is gradually increased to be greater than or equal to a second reference voltage value, a second message is transmitted; the second reference voltage value characterizes the distance of the inductive element 100 from the magnetic element 8 as a second threshold value. The voltage signal sent by the magnetic induction module 1 changes along with the change of the magnetic induction intensity, the first reference voltage value is the voltage value sent by the magnetic induction module 1 when the magnetic induction intensity reaches a first threshold value, and the second reference voltage value is the voltage value sent by the magnetic induction module 1 when the magnetic induction intensity reaches a second threshold value. When the voltage signal is equal to a first reference voltage value, the wireless transmitting module 2 judges that the distance parameter reaches the first threshold value, and when the voltage signal is equal to a second reference voltage value, the wireless transmitting module 2 judges that the distance parameter reaches the second threshold value.

Further, the first threshold includes a plurality of first preset thresholds, and is configured to: being able to switch between a plurality of said first preset thresholds; the second threshold includes a plurality of second preset thresholds and is configured to: the switching between a plurality of said second preset thresholds is enabled. The first preset threshold value and the second preset threshold value are stored in the intelligent terminal 104, the intelligent terminal 104 can be a mobile phone, a tablet, a computer or other equipment, a user selects a proper threshold value through the APP, in some embodiments, multiple threshold value combination recommendations are provided on the intelligent terminal 104, that is, recommendation collocation of multiple groups of first preset threshold values and second preset threshold values prevents the user from adjusting proper values when the user adjusts the threshold values by himself or herself, so that the use is prevented from being affected.

In some embodiments, the wireless transmitting module 2 includes a packet sending queue, and the first message and the second message are sequentially sent to the outside according to the message generating time after being stored in the packet sending queue; and after the message in the packet sending queue is sent, if the message sent last time does not correspond to the judging state, a message corresponding to the judging state is reissued. The wireless transmitting module 2 of the embodiment generates a first message or a second message corresponding to the electric signal change of the magnetic induction module 1, when the first message or the second message is generated, the first message or the second message is packaged and then stored into a packet transmitting queue to be transmitted, and then the packet transmitting queue sequentially transmits outwards from the packet transmitting queue, wherein the packet transmitting queue can store 8 messages at most, the packet transmitting speed of the packet transmitting queue is one second to transmit one message outwards, and the message is repeatedly transmitted for 20 times in the second, so as to prevent a receiving end from not receiving the packet due to electromagnetic interference; when the message generating speed is higher than the packet sending speed, the situation that the packet sending queue is full and the new message is blocked outside the packet sending queue can occur, so that the new message is lost, and the situation that the transmitted door and window opening and closing information does not correspond to the actual door and window opening and closing information can occur. In order to solve this problem, in this embodiment, after the packet sending queue finishes sending the packet, it is checked whether the last sent packet corresponds to the state of the magnetic induction module 1, that is, whether the content of the last sent packet is consistent with the door and window opening and closing information, if not, a packet corresponding to the current state is reissued, and if so, the sending of the packet is ended, so as to avoid that the induction state is inconsistent with the content of the sent packet due to packet loss. In addition, when the packet sending queue is full, the new packet is discarded, and the packet in the queue gradually generates a spare queue in the process of sending the packet to the outside, if a second new packet is generated, the second new packet enters the queue, so that the condition that the second new packet is identical to one packet arranged in front of the second new packet can occur, the packet sending queue sends the same packet, in order to prevent the condition, before the packet is added into the packet sending queue, whether the last packet in the packet sending queue is identical to the new packet is judged, if the packet is different, the packet is allowed to be added into the packet sending queue, otherwise, the packet sending queue cannot be added, thereby not only preventing the inconsistent sensing state and the content of the sent packet due to packet loss, but also avoiding repeated sending of the same packet.

In some embodiments, the sensing assembly 100 is further configured to: and sending a fourth message to the outside at a first appointed time after the first message or the second message is sent, wherein the fourth message is used for indicating whether the current state of the target object is a closed state or an open state. In this embodiment, the message caused by the event is assigned to the event message, and the self-generated message is assigned to the status message. The event message may be understood as a message, such as a first message and a second message, generated in response to a certain trigger signal; the status message may be understood as a message that is self-generated in response to a certain time interval, and is used to indicate the current status of the sensing assembly 100. In a specific embodiment, the first designated time is set to 4 seconds, and after the first message or the second message is sent for 4 seconds, a status message is sent to the outside, where the content of the status message at least includes the opening and closing information of the magnetic induction module 1, which is effective in improving the stability of sensing the opening and closing state of the door and window. In addition, the sensing assembly 100 further includes a button battery 54 and an electric quantity detection module 51, which are electrically connected with the processing chip in the wireless transmitting module 2, the button battery 54 is used for providing electric energy for each module, the electric quantity detection module 51 can detect the electric quantity of the button battery 54, and the content of the status message further includes battery electric quantity information for providing battery electric quantity for the user.

Further, the sensing assembly 100 further includes a light emitting module 52 electrically connected to the wireless transmitting module 2. The light emitting module 52 converts a light emitting frequency and/or a light emitting color in response to an electric signal of the magnetic induction module 1 or the detection switch 3 for indicating an operation state of the switch state detector 101.

In some embodiments, the wireless transmitting module 2 is configured to enter the low power consumption mode within a second specified time after the first message or the second message is sent.

The inventor of the present application found that the existing switch state detector 101 has higher power consumption during the use process, and in order to reduce the power consumption of the switch state detector 101, the inventor of the present application found that, through research of the present application, the wireless transmitting module 2 of the switch state detector 101 has a specified state, and the power consumption of the wireless transmitting module 2 can be effectively reduced by pertinently configuring the working state of the wireless transmitting module 2 based on the specified state. Specifically:

when the wireless transmitting module 2 receives a wake-up instruction in a low power consumption state, the wireless transmitting module may enter a normal working state in response to the wake-up instruction, and send a message to the outside in the normal working state according to the wake-up instruction, and the wake-up instruction may be generated when the magnetic induction intensity sensed by the magnetic induction module 1 reaches a first threshold or a second threshold, for example. In this embodiment, the power consumption of the wireless transmitting module 2 in the low-power-consumption working state is smaller than that in the normal working state, so that the wireless transmitting module 2 is in a relatively low-power-consumption state in the low-power-consumption working state in which the packet-issuing task is not executed, and is switched to the normal working state to issue packets only when being awakened, and compared with the case that the switch state detector 101 is always in the packet-issuing state in the prior art, the power consumption of the switch state detector 101 in this embodiment is lower.

Further, the wireless transmitting module 2 is configured to: in a low power consumption mode, the level signal sent by the magnetic induction module 1 is awakened; the level signal includes a high level or a low level; when the wireless transmitting module 2 is awakened by a high level, setting the next awakening condition as low level awakening; when the wireless transmitting module 2 is awakened by the low level, setting the next awakening condition as the high level awakening. Wherein, the wake-up is understood as entering a normal operation mode from the low power consumption mode. The magnetic induction module 1 of this embodiment is the magnetic switch sensor, and can output the level signal, and the wireless transmitting module 2 includes the processing chip, and a pin of processing chip is connected with the magnetic induction module 1 electricity, can detect the level signal of this pin. In other embodiments, the magnetic induction module 1 may also employ a hall sensor, capable of outputting a voltage signal, and the processing chip is configured to be able to detect the voltage signal of the pin. The following description will be based on an embodiment in which the processing chip is capable of detecting a level signal, and the applicant has found that the processing chip can employ a chip that does not support edge wake-up, thereby reducing the chip volume and the chip cost; the edge wakeup may be understood as being awakened in response to a level transition of a pin. In one embodiment, the processing chip is a TLSR8251 type chip that does not support edge wake-up, but has the advantages of small size, low cost, and low power consumption, and is suitable for the switch state detector 101. Compared with the processing chip used by the existing switch state detector 101, the processing chip can save cost and reduce the volume of the sensing assembly 100.

The used processing chip does not have the function of edge awakening, the awakening is realized through a special algorithm, a general wireless switch only needs to be set with low level awakening, because the wireless switch adopts the detection switch 3 as an induction module, when the detection switch 3 is pressed down, a low level signal is output, when the detection switch 3 is sprung up, a high level signal is output, the detection switch 3 has a self-resetting function, and when the detection switch 3 is pressed down, the detection switch can be automatically sprung up, and only the low level awakening is required to be set under the awakening condition. The high level of the detection switch 3 only exists in the pressed short time and is not in the high level pressing state for a long time, but the switch state detector 101 cannot set a single level signal to wake up in the use process, because the door and the window may be in an open state for a long time or in a closed state for a long time when in use, that is, the level signal of the magnetic induction module 1 may be in a high level for a long time or in a low level for a long time, so that a corresponding wake-up condition needs to be set for the current state of the magnetic induction module 1. Therefore, the wake-up condition of the wireless transmission module 2 is set to: when the wireless transmitting module 2 is awakened by a high level, setting the next awakening condition as low level awakening; when the wireless transmitting module 2 is awakened by the low level, setting the next awakening condition as the high level awakening.

In some embodiments, the sensing assembly 100 is further configured to detect an external pressing operation to generate a third message; the third message is used for controlling the working state of the external device paired with the sensing component 100. It may be understood that the sensing assembly 100 is capable of detecting an external pressing operation to generate the third message, and the sensing assembly 100 is provided with, for example, a detection switch 3, a pressure sensor, a distance sensor, or other electronic components capable of changing an output electrical signal corresponding to the pressing operation, and the wireless transmitting module 2 is electrically connected to the electronic components, when the sensing assembly 100 is subjected to the pressing operation, the electrical signal output by the electronic components changes, and the wireless transmitting module 2 responds to the change of the electrical signal to externally transmit the third message. The third message is used for controlling the working state of the external device, and as described above, the switch state detector 101 provided by the invention is connected with the gateway 102 through bluetooth, and the switch state detector 101 can send a message to the gateway 102 based on bluetooth signals, and can also send a message to the intelligent device 103 based on bluetooth signals. In addition, the smart device 103 may also join the bluetooth network after the network is configured, and communicate with the gateway 102 through bluetooth signals. Further, the data interaction between the switch state detector 101 and the intelligent terminal 104, and the data interaction between the intelligent device 103 and the intelligent terminal 104 may be based on the forwarding of the gateway 102. The intelligent device 103 switches the working state in response to the third message, and the specific control method can be set in the intelligent terminal 104 through the APP, and the scheme enables the switch state detector 101 to be used as a small wireless switch.

Further, the sensing assembly 100 further includes a housing 4 and a detection switch 3, wherein the detection switch 3 is coupled to the housing 4 and can be triggered based on the pressing of the housing 4, so as to generate a trigger signal; the detection switch 3 is electrically connected to the wireless transmission module 2 such that: the wireless transmitting module 2 sends the third message outwards based on the trigger signal. The detection switch 3 is coupled to the housing 4, which may be understood that a specific connection relationship is provided between the detection switch 3 and the housing 4, so that the triggering portion of the detection switch 3 can move along with a part of the housing 4, so that the housing 4 triggers the detection switch 3 when being pressed, and the specific connection relationship may be abutting, fixing, clamping, or non-contact connection.

In some embodiments, the wireless transmitting module 2 is configured to enter a low power consumption mode within a third specified time after the first message, the second message, or the third message is sent, and wake up in response to the trigger signal in the low power consumption mode. The wireless transmitting module 2 comprises the processing chip, the detection switch 3 is connected to one pin of the processing chip, the detection switch 3 outputs a low-level signal when triggered, and the processing chip is set to be awakened when detecting that the pin connected with the detection switch 3 outputs the low-level signal.

Further, the wireless transmitting module 2 is further configured to: if the duration of the continuous triggering of the detection switch 3 is detected to be longer than the appointed duration, a low power consumption mode is entered, and the next wake-up condition is set as the trigger-releasing state of the detection switch 3. Since the sensing assembly 100 is configured to be suitable for detecting an external pressing operation to generate the third message, that is, the switch state detector 101 provided in this embodiment may wirelessly control the working state of other devices, in order to improve the pressing feeling, the portion of the sensing assembly 100 that can be pressed is designed to be relatively large, and in some embodiments, most of the upper surface of the housing 4 may be pressed to trigger the detection switch 3. Since the area of the sensing assembly 100 that can be pressed is too large, during transportation, the pressing area is pressed to trigger the detection switch 3, so that the wireless transmitting module 2 is in a wake-up state, and the electric quantity of the button battery 54 is rapidly exhausted, in order to prevent the above situation, the wireless transmitting module 2 is configured to detect that the duration of the continuous triggering of the detection switch 3 is longer than the designated duration, and then enter a low power consumption mode. In a preferred embodiment, the specified duration is greater than 8 seconds.

Further, the wireless transmitting module 2 is further configured to: if the wireless transmitting module 2 is detected to not transmit the second message within the fourth appointed time after transmitting the first message, waking up and transmitting a fifth message to the outside; the fifth message is used for indicating that the target object is in an open state for a fourth appointed time. When the gateway 102 receives the fifth message, the fifth message is fed back to the intelligent terminal 104, and the intelligent terminal 104 reminds the user that the target object is in the open state for a fourth specified time, so as to remind the user to close the door, the window, the drawer or the wardrobe. In a preferred embodiment, the fourth specified time is greater than or equal to 30 seconds, preventing the user from being reminded too often.

Further, the wireless transmitting module 2 is further configured to: if the wireless transmitting module 2 is detected to enter a low power consumption mode to reach a fifth appointed time, waking up and sending a fifth message to the outside; the fifth message includes the status message, that is, the message content includes at least the opening and closing information of the magnetic induction module 1 and the battery power information, and may also include other status information. In a preferred embodiment, the fifth specified time is set to be greater than or equal to 20 minutes, preventing the wake-up frequency from being too high to cause a decrease in the duration of the button cell 54.

In a preferred embodiment, the fifth specified time is less than 1 second. In this embodiment, a scheme of coexistence of a single-click message and a double-click message is adopted, that is, when the detection switch 3 triggers a single-click instruction, the wireless transmitting module 2 will immediately send the third message to the outside, and when the detection switch 3 triggers a double-click instruction, the wireless transmitting module 2 sends the seventh message to the outside, so that delay of sending the third message by the wireless transmitting module 2 can be reduced, and user experience is improved. The content of the seventh message characterizes the OTA upgrade, so that even if the detection switch 3 is triggered by mistake to double-click instructions, the normal use of the switch-on state sensing device is not affected.

Further, as shown in fig. 5, 7 and 8, the switch state detector 101 provided by the present invention further includes a sealing member 6, where the sealing member 6 is disposed along a circumference of the first housing 41, and the sealing member 6 is clamped between the first housing 41 and the second housing 42, so as to realize sealing connection between the first housing 41 and the second housing 42. The sealing member 6 is made of elastic sealing material, such as rubber, silica gel, etc., and can be pressed to achieve sealing effect. The arrangement of the sealing element 6 along the circumference of the first housing 41 is understood to mean that the sealing element 6 has a ring-shaped structure, the shape of which corresponds to the shape of the first receiving groove 414 of the first housing 41. Further, the sealing member 6 is disposed in the first accommodating groove 414, and the sealing member 6 is clamped between the inner wall of the first accommodating groove 414 and the second housing 42, so that the first accommodating groove 414 and the second housing 42 form a sealed cavity. The sealing member 6 is installed in the first accommodating groove 414 and is attached to the top wall or the side wall of the first accommodating groove 414, and the second casing 42 compresses the sealing member 6 on the top wall or the side wall of the first accommodating groove 414, so as to realize the sealing connection between the first casing 41 and the second casing 42.

Further, as shown in fig. 5 and 6, the first housing 41 generates the pressing motion in response to the pressing force, presses the seal member 6 to be elastically deformed, and thus the seal member 6 generates a restoring force against the elastic deformation, and when the pressing force is removed, the restoring force supports the first housing 41 to be restored to its original position. Because the volume of the switch state detector 101 needs to be made small, the sealing member 6 has the functions of waterproof sealing and restoring force, so that the first shell 41 does not need to be designed with a special restoring member, the internal structure of the sensing assembly 100 is simplified, and the volume is reduced.

Further, as shown in fig. 5 and 8, the sealing member 6 is a sealing ring, and the width of the cross section of the sealing ring in the first direction is greater than the width of the cross section in the third direction, where the first direction is a direction in which the first housing 41 is away from the second housing 42, and the third direction is perpendicular to the first direction. The width of the cross section of the sealing ring in the first direction is greater than the width of the cross section of the sealing ring in the third direction, which is the vertical upward direction in fig. 5, and the width of the cross section of the sealing ring in the third direction is understood to be greater than the horizontal width, for example, a rectangular cross section, an oval cross section, and the like, and in a specific embodiment, the cross section of the sealing ring is an oval with a transverse diameter of 1.8mm and a longitudinal diameter of 3 mm. The advantage of this design is that the compression margin in the vertical direction of the sealing ring is increased, so that the first housing 41 can be triggered by a sufficient pressing margin when pressed. Meanwhile, the restoring force can be reduced by increasing the compression allowance of the sealing ring in the vertical direction, so that the first shell 41 is pressed more labor-saving, and the pressing hand feeling is improved.

In another embodiment, the first housing 41 includes a first end and a second end remote from the first end, and the detection switch 3 is disposed at the first end of the first housing 41; the sealing member 6 is a sealing ring, the cross section of the sealing ring at the position corresponding to the first end is a first cross section, the cross section of the sealing ring at the position corresponding to the second end is a second cross section, and the area of the first cross section is larger than that of the second cross section (not shown in the figure). The seal ring can be understood as an annular structure with a variable cross section, the cross section of the seal ring near the first end is thicker, the cross section near the second end is thinner, and the thickness of the cross section is gradually changed. The reason for this is that, since the detection switch 3 is disposed at the first end, the first end of the first housing 41 is pressed to trigger the detection switch 3, the seal ring is flattened during long-term pressing of the first end, and the second section is not pressed, so that the sealing effect of the seal ring at the first end is deteriorated. Therefore, the sealing ring is designed into a structure with gradually changed thickness, is thicker near the first end, is not easy to flatten in long-term pressing, and provides better waterproof sealing effect in long-term use.

Further, as shown in fig. 8, the second housing 42 includes a bottom shell 425 and a sealing portion 426, the sealing portion 426 extends from a periphery of the edge of the bottom shell 425, and the sealing portion 426 presses the sealing member 6 against the inner wall of the first accommodating groove 414, so as to realize sealing connection between the first housing 41 and the second housing 42.

The sealing portion 426 may be understood that the sealing portion 426 abuts against the inner wall of the first accommodating groove 414, the top surface of the sealing portion 426 abuts against the lower surface of the sealing portion 6, so that the upper surface of the sealing portion 6 abuts against the top surface of the first accommodating groove 414, and the distance between the top surface of the sealing portion 426 and the top surface of the first accommodating groove 414 is smaller than the thickness of the sealing portion 6 in the vertical direction, so that a sealing structure is formed between the first accommodating groove 414 and the second housing 42, thereby providing a better sealing effect. At the same time, the seal 6 can provide a return force which assists in its return after the first housing 41 has been brought into a pressing movement.

The seal ring is clamped in the seal ring placement area 416, it is understood that the seal ring has elasticity, the inner ring Zhou Changshi of the seal ring is configured on the circumference of the seal ring placement area 416, and the cross section transverse width of the seal ring is slightly larger than the width of the seal ring placement area 416, so that the seal ring is in interference fit with the seal ring placement area 416, and thus the seal ring can be stably placed in the seal ring placement area 416, and the assembly is convenient. The seal ring limiting portion 415 is formed by combining a plurality of seal ring limiting ribs 4151, specifically, the seal ring limiting portion 415 leaves a clearance gap at the corresponding positions of the four first buckles 411, and leaves a clearance gap at the corner of one side far away from the detection switch 3, so as to form a plurality of seal ring limiting ribs 4151, wherein the purpose of setting the clearance gap at the corresponding positions of the first buckles 411 is to reserve deformation for the first buckling positions 421, so that the first buckles 411 can be smoothly separated from the first buckling positions 421 when the first shell 41 is disassembled; the corner far away from one side of the detection switch 3 is provided with a clearance space, because the circuit board 5 is installed on the sealing ring limiting frame 4151 through a buckle, the circuit board 5 abuts against the end part of the sealing ring limiting frame 4151, and the clearance space is reserved for an antenna module on the circuit board 5. The top surface of the first accommodating groove 414 is hollowed inward to form an avoidance portion 419, and the avoidance portion 419 is arranged to be concave and is used for reserving an avoidance space for electronic elements on the circuit board 5, so that the circuit board 5 can be adapted to different modules.

Further, as shown in fig. 5, 7 and 10, the circuit board 5 is mounted on the first housing 41 and is disposed inside the sealed cavity, and the detection switch 3 is disposed on a surface of the circuit board 5 facing the second housing 42; when the first housing 41 responds to the pressing force to generate the pressing motion, the first housing 41 drives the detection switch 3 to move towards the second housing 42, and then the second housing 42 presses against and triggers the detection switch 3. The circuit board 5 is mounted on the first housing 41, the seal ring limiting frame 4151 of the first housing 41 is provided with four circuit board buckles 417 in a protruding manner, corresponding positions on the circuit board 5 are provided with circuit board buckling positions 53 in a recessed manner, the width of the circuit board buckling positions 53 is adapted to the width of the circuit board buckling positions 417, the circuit board 5 is limited in the horizontal direction, the circuit board 5 is clamped to the seal ring limiting frame 4151 through the circuit board buckling positions 417, and the upper surface of the circuit board 5 is abutted to the end portion of the seal ring limiting frame 4151, so that the circuit board 5 is limited in the vertical direction.

The exterior mounting surfaces to which the housing 4 and the third housing 824 are mounted are not the same, and in one embodiment the housing 4 is adhered to the door frame by double sided adhesive and the third housing 824 is adhered to the door panel by double sided adhesive.

The distance between the magnetic induction module 1 and the first surface 45 is set to be a first distance, the distance between the center position of the permanent magnet 81 and the second surface 821 is set to be a second distance, and the absolute value of the difference between the first distance and the second distance is smaller than 8mm. Since the first surface 45 and the second surface 821 are fixed on the external mounting surface, the difference between the first distance and the second distance is set to be less than 8mm, so that the center position of the permanent magnet 81 and the position of the magnetic induction module 1 are close to each other in the first direction, and the induction distance of the magnetic induction module 1 is accurate, and the first direction is the direction in which the housing 4 faces the first surface 45 and is perpendicular to the first surface 45, namely, the direction indicated by the arrow in fig. 15. In this embodiment, through experiments by research and development personnel, when the installation interval between the housing 4 and the third housing 824 is 10mm, the switch state detector 101 is identified as "off" when the distance between the magnetic induction module 1 and the center position of the permanent magnet 81 in the first direction is less than 16mm, and the switch state detector 101 is identified as "on" when the distance between the magnetic induction module 1 and the center position of the permanent magnet 81 in the first direction is greater than 21 mm. Therefore, the distance between the center of the permanent magnet 81 and the magnetic induction module 1 in the first direction cannot be too large, and when the distance is less than 8mm, the induction distance is optimal.

Further, as shown in fig. 8, the first surface 45 and the second surface 821 are respectively provided with a double-sided adhesive part 91, and the double-sided adhesive part 91 may be a groove or a mark. The shape of the double-sided tape pasting part 91 is adapted to the double-sided tape 9, so that the double-sided tape 9 can be pasted on the double-sided tape pasting part 91, and the double-sided tape pasting part 91 is convenient for pasting the double-sided tape on the center of the first surface 45 or the second surface 821.

According to another aspect of the present invention, as shown in fig. 2, there is also provided a switch state detection method applied to a switch state detector 101; the detection method is characterized by comprising the following steps: detecting a distance parameter between a magnetic element 8 and a sensing element 100; the distance parameter is used to indicate the distance between the magnetic assembly 8 and the inductive assembly 100;

if the distance parameter is gradually reduced to a first interval taking a first threshold value as an end point, a first message is sent to the outside; the first message is used for indicating that a target object associated with the sensing assembly 100 is in an open state;

if the distance parameter is gradually increased to a second interval taking a second threshold value as a starting point, a second message is sent to the outside; the second message is used for indicating that the target object associated with the sensing assembly 100 is in a closed state; the first interval and the second interval are not coincident, and the difference value between the second threshold value and the first threshold value is greater than or equal to 1mm.

The technical details of the above method are described in detail above, and are not described here again. The existing switch state detector is too small in the distinction of the induction conditions of the two states of "on" and "off", so that when the distance between the magnetic component 8 and the induction component 100 reaches a critical value, the magnetic induction intensity generated by the magnetic component 8 is influenced by the environment and fluctuates, and the magnetic induction module 1 in the induction component 100 detects that the magnetic induction intensity also fluctuates, so that the induction state of the induction component 100 is repeatedly switched between "on" and "off", so that the intelligent device 103 connected with the intelligent device repeatedly switches the working state, and the controlled intelligent device is damaged. The applicant discloses a switch state detector 101, by setting the difference between the first threshold and the second threshold to be greater than or equal to 1mm, so that a hysteresis interval of at least 1mm is provided between the first interval and the second interval, when the distance parameter reaches the hysteresis interval, the sensing state of the sensing component 100 is not changed, and the last sensing state is maintained. When the hysteresis interval which is more than or equal to 1mm is set, the sensing state of the sensing assembly 100 can be effectively prevented from being repeatedly switched when the distance parameter reaches a certain critical value, so that the intelligent device 103 connected with the sensing assembly 100 is protected from being repeatedly switched to the working state.

In some embodiments, the method further comprises: if the distance parameter is detected to be changed from the second interval to the first interval, a first message is sent to the outside; and if the distance parameter is detected to be changed from the first interval to the second interval, sending a second message to the outside.

The technical details of the above method are described in detail above, and are not described here again. Because of the existence of the hysteresis section, the situation that the distance parameter enters the first section or the second section from the hysteresis section in response to the position change of the magnetic component 8 and the sensing component 100 may occur, at this time, it needs to be judged whether the section before entering the hysteresis section is the same as the section after entering the hysteresis section, if so, no message is sent, and if not, a corresponding message is sent, so that repeated sending of the message can be effectively prevented.

In some embodiments, the method further comprises: the sensing component 100 is triggered to generate and send a third message to the outside in response to an external pressing force; the third message is used for controlling the working state of the external device paired with the sensing component 100. The technical details of the above method are described in detail above, and are not described here again. The method enables the switch state detector 101 to be used as a sensor for detecting the opening and closing of doors and windows and also can be used as a small wireless switch.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
