[0002] In modern industrial and daily life applications, sensors based on wireless radio frequency technology are widely used to monitor various parameters, such as temperature and humidity. Since the monitoring environment of the sensor usually has a certain shielding effect on the sensor data transmission, the data transmission distance will be greatly shortened. For example, wireless temperature probes are usually inserted into the food and placed in the oven to monitor the temperature in real time. Since most ovens are made of metal, the transmission distance of the temperature probe based on the wireless radio frequency solution is greatly affected, and it cannot meet the user's needs for remote perception of cooking temperature and cooking progress.

[0003] In related technologies, intermediate devices such as repeaters are usually set up to forward sensor data to expand the data transmission range, so that users can obtain accurate data in a timely manner even if they are far away from the sensor. However, adding repeater sensor components also brings a new challenge: how to efficiently achieve matching between sensors and repeaters in actual application scenarios and production assembly lines, especially in the production assembly workshop where there is interference from a large number of sensors.

[0021] The present application provides a sensor component matching method, a sensor matching method and related devices, which are used to achieve efficient matching between sensors and repeaters.

[0022] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] The sensor component matching method of the present application can be applied to realize the binding of wireless sensors and repeaters on the production assembly line, and can also be used for the binding between wireless sensors and repeaters in the terminal user scenario. The executor of the present application can be a repeater, or a sensor component, a sensor component matching device, a sensor component matching system or a terminal, which is not limited here.

[0024] For ease of understanding, the present application embodiment takes the sensor component matching system as an example for explanation. Figure 1 , the first embodiment of the sensor component matching method in the present application includes:

[0025] 101. Execute at least one target measure for changing a sensor state on a to-be-matched sensor to obtain a target state feature.

[0026] This embodiment provides a repeater, including a first communication unit and a second communication unit, and the sensor to be matched includes a third communication unit.

[0027] The first communication unit is communicatively connected to the third communication unit, the repeater receives the sensor status data through the first communication unit, the second communication unit is communicatively connected to the host computer, and the repeater forwards the sensor status data to the host computer through the second communication unit.

[0028] The sensor of this embodiment can be any sensor such as a temperature sensor, a humidity sensor, a gas concentration sensor, a pressure sensor, etc., which transmits the measured environmental parameters through wireless radio frequency technology. This embodiment does not impose any specific restrictions on the type of sensor and the specific number of acquisition units.

[0029] The above-mentioned communication units can adopt any wireless radio frequency technology such as Bluetooth, low-power Bluetooth, 433MHz frequency band, etc. For example, the first communication unit and the third communication unit are set to adopt the 433MHz frequency band solution to achieve communication connection, and the second communication unit is set to adopt Bluetooth, low-power Bluetooth solution to improve the use scenario of repeater forwarding, so that mobile phones and other host computers can also obtain the forwarded sensor status data.

[0030] Specifically, the sensor component matching system controls the relay and the to-be-matched sensor to start up, executes at least one target measure of changing the sensor state on the to-be-matched sensor, and obtains a target state feature.

[0031] In this embodiment, the target measures are used to indicate operations that change the state of the sensor, including charging state change measures and environmental parameter change measures; wherein, the charging state change measures are used to indicate operations that change the charging state of the sensor, such as placing it in a charging compartment, taking it out of the charging compartment, and alternately placing it in and taking it out according to a certain rule; the environmental parameter change measures are used to indicate operations that change the environmental parameters collected by the sensor, such as for a food temperature probe, through heating operations and / or cooling operations, it is also possible to set a corresponding target temperature according to a certain temperature change rate, and control the temperature to change in a certain regular manner, etc.

[0032] In this embodiment, the target state characteristics are used to indicate the changing characteristics of the sensor state data. The target state characteristics correspond to at least one target measure executed. The target state characteristics may include one or more state characteristics depending on the type of target measure, measure parameters, execution sequence, measure duration, measure change law, etc.

[0033] It is understandable that when the sensor component matching system performs batch matching, it can set targeted target measures for each sensor to be matched to achieve simultaneous pairing of multiple probes to be matched, such as setting multiple environmental parameters to achieve simultaneous pairing of multiple groups of sensors and repeaters.

[0034] The host computer may be a sensor component matching system, or a mobile phone, computer, tablet computer, etc.

[0035] 102. In response to the observation instruction, when the repeater searches for a sensor to be matched that matches the target state feature, a paired sensor component is determined.

[0036] The sensor component matching system generates an observation instruction and sends it to the repeater. In response to the observation instruction, the repeater searches for a sensor to be matched that matches the target state characteristics and obtains a paired sensor component.

[0037] The above observation instructions are used to control the repeater to find the sensor to be matched with the target state characteristics to achieve matching, that is, the observation instructions correspond to the target state characteristics one by one.

[0038] In this embodiment, by executing at least one target measure of changing the sensor state on the sensor to be matched, the sensor state is changed. By observing one or more change factors during pairing, sensor component matching can be achieved, avoiding interference from other sensors. This is suitable for automated pairing of sensors and repeaters in large-scale production, reducing labor costs and improving pairing efficiency.

[0039] In production assembly scenarios, there is a need to pair batches of sensors and repeaters at the same time. To meet the accuracy requirements of batch matching, please refer to Figure 2 , the second embodiment of the sensor component matching method in the present application includes:

[0040] 201. Execute charging state change measures and environmental parameter change measures on the sensor to be matched to obtain target state characteristics.

[0041] Specifically, the sensor component matching system controls the relay and the to-be-matched sensor to start up, executes charging state change measures and environmental parameter change measures on the to-be-matched sensor, and obtains target state characteristics.

[0042] The target state characteristics of this embodiment include at least one charging state change characteristic and at least one environmental parameter change characteristic, wherein the charging state change characteristics include but are not limited to charging measure parameter characteristics, charging measure duration characteristics, and charging measure change law characteristics; the environmental parameter change characteristics include but are not limited to environmental parameter characteristics, environmental parameter change law characteristics, and environmental change measure duration characteristics; the target state characteristics may also include any combination of the start and end times of the occurrence of the above characteristics, the order of occurrence of the above characteristics, etc.

[0043] It can be understood that the sensor component matching system can also only execute charging state change measures or environmental parameter change measures for the matching sensor, and the target state characteristics include at least one charging state change characteristic that can be executed according to at least one target measure, such as the third embodiment of the sensor component matching method described below, or at least one environmental parameter change characteristic, such as the fourth embodiment of the sensor component matching method described below.

[0044] 202. In response to the observation instruction, determine whether the repeater has searched for a sensor to be matched that matches the target state feature.

[0045] Specifically, the sensor component matching system generates an observation instruction and sends it to the repeater. In response to the observation instruction, the repeater obtains the sensor state data of the sensor to be matched, and determines whether the sensor state data has the target state characteristics. If it has the target state characteristics, the sensor to be matched is determined as the target matching sensor; if it does not have the target state characteristics, the target matching sensor is not searched.

[0046] Among them, the sensor status data may include the collected measured environmental parameters and sensor working parameters; the measured environmental parameters are environmental parameters collected by the sensor. For example, if the sensor is a food temperature probe, the measured environmental parameters are temperature, and the sensor working parameters are parameter information of the sensor itself, such as charging status, power-on status, sleep status, battery power, battery voltage, charging time, charging stop time, etc.

[0047] Exemplarily, the repeater also includes an output charging unit and a repeater control unit, such as a microcontroller unit (MCU). The repeater control unit is connected to the output charging unit and is used to control the output charging unit to charge and stop charging the matching sensor. When the charging state change measure is executed, the matching sensor is charged and stopped through the output charging unit of the repeater.

[0048] 203. If yes, bind the target matching sensor corresponding to the repeater to obtain the successfully paired sensor component.

[0049] Specifically, if the repeater searches for a sensor to be matched that matches the target state feature, pairing is performed to bind the target matching sensor corresponding to the repeater to obtain a successfully paired sensor component.

[0050] 204. If not, replace the sensor and execute step 201.

[0051] Specifically, if the repeater does not search for a sensor to be matched that matches the target state feature, the sensor is replaced and re-paired.

[0052] Optionally, the sensor to be matched is marked as defective and a prompt message is generated.

[0053] In this embodiment, by executing charging state change measures and environmental parameter change measures on the matching sensor to change the sensor state, the target state characteristics generated based on the charging state change measures and the environmental parameter change measures have richer feature dimensions. Matching sensor components based on the target state characteristics of this embodiment can improve the reliability and accuracy of matching, avoid interference from other sensors, and reduce the collision probability of large-scale matching. It is also suitable for automated pairing of sensors and repeaters in large-scale production, which reduces labor costs and improves pairing efficiency.

[0054] During the cooking process, monitoring the temperature inside the food is particularly important for determining whether the food has reached the target maturity temperature. Usually, the food temperature probe of the temperature measurement component is inserted into the food, and the temperature data collected by the food temperature probe is transmitted to the terminal based on wireless radio frequency technology. Since the material of the cooking vessel has a strong shielding effect, it interferes with the data transmission of the food temperature probe. Adding a repeater can effectively expand the data transmission range of the food temperature probe so that the user can know the cooking progress in time when he is far away from the cooking vessel. However, it also brings a problem. It is necessary to achieve efficient matching between the food temperature probe and the repeater. Taking the temperature measurement component as an example, refer to the following Figure 3 The third embodiment of the sensor component matching method of the present application is described as follows:

[0055] 301. Execute charging state change measures on the food temperature probe to obtain charging state change characteristics.

[0056] In this embodiment, the charging status change measure is used to indicate an operation of changing the charging status of the food temperature probe, such as placing the probe into the charging compartment, taking the probe out of the charging compartment, and placing and taking the probe in alternatingly according to a certain rule.

[0057] In this embodiment, the charging state change feature is used to indicate the charging state change characteristics of the food temperature probe caused by the execution of the charging state change measure. The charging state change feature includes but is not limited to the charging measure parameter feature, the charging measure duration feature, the charging measure change rule feature, etc., such as charging voltage, charging duration, charging amount, charging rate, charging frequency, etc.

[0058] When performing batch matching, different charging state change measures can be performed on each food temperature probe to obtain different charging state change characteristics of each food temperature probe to achieve batch matching. The charging state change measure strategy can be a combination of any one or more of the above operations.

[0059] Optionally, each food temperature probe is charged according to a different charging time, and the charging time corresponding to each food temperature probe is determined as a charging state change feature. For example, charging for 500ms, 1000ms, 1500ms, and 2000ms is performed respectively to achieve simultaneous matching of four food temperature probes. This embodiment achieves batch matching through multiple measure parameters of a charging measure, thereby ensuring matching speed and accuracy.

[0060] Optionally, the food temperature probes to be matched are charged and stopped alternately, and the charging state and the charging stop state are encoded to obtain a charging state change coding sequence; the charging state change coding sequence is determined as the charging state change feature. In this embodiment, the charging state change coding sequence is used as the charging state change feature. As the number of food probes to be matched increases and / or the matching accuracy requirements increase, a more complex charging state change coding sequence can be formulated for each food probe to be matched. This has high flexibility and can be applied to large-scale simultaneous matching needs in a workshop.

[0061] Specifically, the detection circuit can detect the charging state of the food temperature probe and / or the charging state of the charged probe by the repeater, set a first level signal corresponding to the charging state, and stop charging to correspond to a second level signal.

[0062] For example, the first level signal is represented by encoding "1", and the second level signal is represented by encoding "0". Based on this, alternating charging and stopping charging can generate a square wave composed of the first level signal and the second level signal, that is, a set of 0101-like binary codes composed of the codes "1" and "0" can be obtained to achieve high-precision pairing.

[0063] It is understandable that binary coding is a possible example, and other coding schemes can also be used for matching. For example, the corresponding coding scheme can be further set according to the change of charging voltage, the change of charging time, etc., so as to better extract the characteristics of charging state changes and improve the accuracy of the description of charging state change characteristics.

[0064] 302. In response to the observation instruction, determine whether the repeater has searched for a food temperature probe that matches the charging state change characteristic.

[0065] Specifically, the temperature measurement component matching system generates an observation instruction and sends it to the repeater, where the observation instruction includes the charging state change characteristics; in response to the observation instruction, the repeater obtains the probe status data of the food temperature probe, and determines whether the probe status data has the charging state change characteristics. If it has the charging state change characteristics, the food temperature probe is determined to be a paired probe; if it does not have the charging state change characteristics, the paired probe is not searched for.

[0066] Exemplarily, the charging state change characteristic is a charging state change coding sequence, and the repeater observes whether there is a food temperature probe with the charging state change coding sequence; if a food temperature probe carrying a matching charging state change coding sequence is observed, the food temperature probe is determined to be a paired probe; if no food temperature probe carrying a matching charging state change coding sequence is observed, no paired probe is searched for.

[0067] The food temperature probe in the temperature measuring assembly of this embodiment is a rechargeable temperature acquisition device, and the repeater is a radio frequency forwarding device that can charge the food temperature probe. Figure 4 A temperature measuring component is provided. The temperature measuring component 400 of this embodiment includes a repeater 41 and a food temperature probe 42. The repeater 41 is provided with at least one charging compartment, such as Figure 4 The repeater 41 is provided with a charging compartment 411 , and the food temperature probe 42 can be placed in the charging compartment 411 for charging.

[0068] Repeater 41 can forward the received probe data to the host computer via radio frequency, see Figure 5 A structural block diagram of a repeater is shown, the repeater comprises an output charging unit 501 and a first communication unit 502, the output charging unit 501 is used to charge the food temperature probe, and the first communication unit 502 is used to receive probe status data.

[0069] The above-mentioned repeater also includes a repeater control unit 503, such as a microcontroller unit (MCU) and a second communication unit 504. The repeater control unit 503 is electrically connected to the output charging unit 501, the first communication unit 502 and the second communication unit 504 respectively to realize the repeater control. The second communication unit 504 is communicatively connected with the host computer for reporting the food temperature probe status data, wherein the host computer can be a mobile phone, a computer, a tablet computer, etc.

[0070] The repeater control unit 503 can obtain the food temperature probe status data through the first communication unit, and forward it to the host computer through the second communication unit 504 to realize the forwarding function of the repeater.

[0071] The above-mentioned repeater control unit 503 can obtain the output charging data when the output charging unit 501 charges the power storage unit through the detection unit, and compare it with the food temperature probe status data obtained by the first communication unit 502 to achieve matching between the food temperature probe and the repeater, wherein the output charging data can be the charging voltage, charging current, charging amount, charging time, charging stop time, etc.

[0072] In this embodiment, the food temperature probe includes a collection unit, a third communication unit and a power storage unit. The power storage unit supplies power to the collection unit and the third communication unit respectively. The collection unit is used to collect the current measured environmental parameters; the third communication unit uses wireless radio frequency technology to broadcast the food temperature probe status data to the outside.

[0073] The food temperature probe of this embodiment is internally provided with a battery, a temperature sensor, a circuit board and a wireless transmitter, wherein the temperature sensor is used to measure the temperature of food, the battery is used to power the circuit board, and the wireless transmitter is used to broadcast the temperature signal measured by the temperature sensor in the form of a wireless signal.

[0074] A probe control unit is arranged on the circuit board, and the probe control unit includes a detection circuit to detect current battery status data or input charging data. The wireless transmitter includes a third communication unit connected to the circuit board, and an antenna connected to the radio frequency circuit, and the antenna is used to transmit the probe status data.

[0075] Among them, the battery status data is the data collected by the charging shutdown type probe detection circuit. Since the food temperature probe is turned off during charging, the actual charging data of the built-in battery cannot be detected. The battery power of the current startup and the battery power when it was last shut down in the battery status data can be used to determine the charging power of the probe by the external power supply, which is called the second charging power for easy distinction. For the charging sleep type or normally open type probe, the charging status of the probe by the external power supply can be directly detected.

[0076] The battery is a power storage unit such as a rechargeable supercapacitor or a rechargeable lithium battery, and is charged through charging contacts arranged on the battery; when the food temperature probe is placed in the charging compartment of the repeater, the charging contacts of the battery are electrically connected to the charging contacts in the charging compartment.

[0077] It can be understood that both the input charging data and the battery status data are used to indicate the battery status detected by the food temperature probe, wherein the battery status data is used to indicate the battery power, battery voltage, etc. when the power is turned on, and the input charging data is used to indicate the battery charging status during the probe sleep process and the power-on process.

[0078] Optionally, the temperature sensor may include one, two or more, for example, two temperature collection units are arranged according to the axis direction of the probe, wherein the first temperature sensor is used to collect the internal temperature of the food, and the second temperature sensor is used to collect the internal temperature of the cooking vessel, such as the internal temperature of the oven.

[0079] Furthermore, if the food temperature probe is placed in the charging compartment of the repeater to execute charging state change measures, the source of the charging state change characteristics used to execute the match may include the characteristic information formulated by the temperature measurement component matching system (for easy distinction, called the first charging state change characteristic), and the characteristic information carried by the probe state data broadcast by the food temperature probe after executing the corresponding target measure strategy (for easy distinction, called the second charging state change characteristic). The detection circuit inside the repeater can also obtain the characteristic information corresponding to the output charging unit executing the corresponding target measure on the food temperature probe (for easy distinction, called the third charging state change characteristic).

[0080] Optionally, the repeater may determine the paired food temperature probe by comparing whether the second charging state change characteristic matches the third charging state change characteristic;

[0081] Optionally, the repeater may also determine the paired food temperature probes by comparing whether the first charging state change characteristic matches the second charging state change characteristic.

[0082] Optionally, the repeater can also determine the paired food temperature probes through double verification by comparing whether the first charging state change characteristic matches the second charging state change characteristic, and comparing whether the second charging state change characteristic matches the third charging state change characteristic, thereby improving the reliability of the matching.

[0083] 303. If yes, bind the food temperature probe corresponding to the repeater to obtain a successfully paired temperature measurement component.

[0084] Specifically, if the repeater searches for a food temperature probe that matches the charging state change characteristics, pairing is performed to bind the food temperature probe corresponding to the repeater to obtain a successfully paired temperature measurement component.

[0085] 304. If not, replace the food temperature probe and re-execute the above step 301.

[0086] Specifically, if the repeater fails to search for a food temperature probe that matches the charging state change feature, the food temperature probe is replaced and the above step 301 is executed again.

[0087] In this embodiment, charging state change measures are executed on the food temperature probe to change the probe state and obtain charging state change characteristics. Matching of the temperature measurement components based on the charging state change characteristics can achieve fast matching, and charging state change measures for each food temperature probe can be flexibly formulated according to the number of food probes to be matched and the matching accuracy requirements, thereby improving the matching reliability and accuracy, avoiding interference from other sensors, and reducing the collision probability of large-scale matching. It is also suitable for automated pairing of sensors and repeaters in large-scale production, which reduces labor costs and improves pairing efficiency.

[0088] This embodiment continues to take the temperature measurement component as an example, see Figure 6 The fourth embodiment of the sensor component matching method of the present application is described as follows:

[0089] 601. Perform environmental temperature change measures on the food temperature probe to obtain temperature change characteristics.

[0090] In this embodiment, the environmental temperature change measure is used to indicate the operation of changing the environmental temperature of the food temperature probe, such as raising the temperature to the target temperature, lowering the temperature to the target temperature, and controlling the temperature change according to a certain rule.

[0091] In this embodiment, the temperature change characteristics are used to indicate the actual measured ambient temperature change characteristics collected by the food temperature probe caused by the execution of the ambient temperature change measures; the temperature change characteristics include but are not limited to temperature parameter characteristics, temperature change law characteristics, and ambient temperature change measure duration characteristics, such as temperature value, temperature difference value, temperature change rate, temperature change duration, the start and end time of the ambient temperature change measures, etc.

[0092] When performing batch matching, different environmental temperature change measures can be performed on each food temperature probe to obtain different temperature change characteristics of each food temperature probe to achieve batch matching. The environmental temperature change measure strategy can be a combination of any one or more of the above operations.

[0093] Optionally, each food temperature probe is heated according to different target temperatures, and the measured ambient temperature corresponding to each food temperature probe is determined as the temperature state change characteristic. For example, the temperature measurement component matching system has 8 sets of key pairing temperatures within the range of 40 to 80°C: 40, 45, 50, 55, 60, 65, 70, 75, 80°C, and 8 sets of food temperature probes and repeaters are paired at the same time.

[0094] Optionally, the food temperature probe of this embodiment may include multiple temperature sensors arranged along the axial direction. The environmental temperature change measures executed on the food temperature probe can achieve the goal of setting different target temperatures for each temperature sensor through temperature isolation measures, so as to use the different measured environmental temperatures collected by each temperature sensor in the same probe broadcast as temperature change characteristics, so as to enrich the feature dimensions of comparison of each food temperature probe.

[0095] 602. In response to the observation instruction, determine whether the repeater has searched for a food temperature probe that matches the temperature change characteristic;

[0096] Specifically, the temperature measurement component matching system generates an observation instruction and sends it to the repeater, where the observation instruction includes a temperature change characteristic; in response to the observation instruction, the repeater obtains the probe status data of the food temperature probe and determines whether the probe status data has a temperature change characteristic. If it has a temperature change characteristic, the food temperature probe is determined to be a paired probe; if it does not have a temperature change characteristic, the paired probe is not searched for.

[0097] Exemplarily, the temperature change characteristic is a target temperature value that rises rapidly, and the repeater observes whether there is a food temperature probe with the target temperature value that rises rapidly; if a food temperature probe with the target temperature value that rises rapidly is observed, the food temperature probe is determined to be a paired probe; if no food temperature probe with the target temperature value that rises rapidly is observed, no paired probe is searched for.

[0098] 603. If yes, bind the food temperature probe corresponding to the repeater to obtain a successfully paired temperature measurement component;

[0099] Specifically, if the repeater searches for a food temperature probe that matches the temperature change characteristics, pairing is performed to bind the food temperature probe corresponding to the repeater to obtain a successfully paired temperature measurement component.

[0100] Optionally, the repeater control unit in this embodiment can obtain the output charging data of the output charging unit when charging the matching sensor through the detection circuit, wherein the output charging data is used to indicate the output charging status of the matching sensor detected by the repeater; the output charging data includes first charging data and charging stop time, and the first charging data may include charging duration, charging voltage, charging amount, etc.

[0101] Optionally, after the repeater searches for a to-be-matched sensor that matches the target state feature, the method further includes: performing sensor matching according to the sensor state data and the output charging data to obtain the target matching sensor, wherein the sensor state data is the sensor state data broadcast by the to-be-matched sensor, and the output charging data is the charging data of the to-be-matched sensor by the repeater. This embodiment performs double verification on the output charging data detected by the repeater to ensure the reliability of the matching.

[0102] Exemplarily, for a normally-open sensor, that is, the sensor is in working state during charging, it can broadcast data externally, and the sensor status data includes the battery voltage and the charging status indicator; the above-mentioned sensor matching is performed based on the sensor status data and the output charging data to obtain the target matching sensor, including: if a sensor to be matched is searched for whose charging voltage in the output charging data matches the battery voltage and carries a charging status indicator, the sensor to be matched is determined as the target matching sensor.

[0103] Exemplarily, for a charging shutdown type sensor, since the sensor is in a shutdown state when charging, it is unable to broadcast the sensor status data externally. To match the charging shutdown type sensor, it is necessary to charge it first, then stop charging and restart the sensor to obtain the sensor status data. The above-mentioned sensor matching based on the sensor status data and the output charging data to obtain the target matching sensor includes: controlling the repeater to stop charging the sensor to be matched and obtaining the output charging data; obtaining the power-on working status data of the sensor to be matched that is powered on and broadcasted; if a sensor to be matched whose power-on working status data matches the output charging data is searched, the sensor to be matched is determined as the target matching sensor, otherwise it is matched again.

[0104] Among them, the power-on working status data is used to indicate the sensor status data when the sensor is just turned on; the power-on working status data may include a just-power-on mark and a power-on working time, and the above-mentioned output charging data includes a stop charging time. Specifically, if a sensor to be matched is found whose stop charging time matches the power-on working time and carries a just-power-on mark, the sensor to be matched is determined as the target matching sensor.

[0105] It is understandable that due to hardware limitations, there may be millisecond-level errors between the power-on timing and the charging stop timing of the charging shutdown type sensor. The difference between the above-mentioned charging stop time and the power-on working time is within the preset error range, and combined with other information such as the power-on mark, the charging power and the matching of the two most recent battery power parameters, the reliability of the matching between the sensor and the repeater can be guaranteed.

[0106] Exemplarily, for charging dormant sensors, when charging, the sensor chip is in a dormant state and cannot broadcast data, but the current input charging data can still be saved. Such as whether it is charging, charging time, charging stop time, battery power, battery voltage and other information. For matching charging dormant sensors, it is necessary to charge first, then stop charging and restart the sensor to obtain sensor status data; the above sensor matching based on sensor status data and output charging data to obtain the target matching sensor includes: stopping charging of the sensor to be matched through a repeater to obtain output charging data; obtaining the wake-up working status data of the sensor to be matched to resume working broadcast; if a sensor to be matched whose wake-up working status data matches the output charging data is searched, the sensor to be matched is determined as the target matching sensor, otherwise it is matched again.

[0107] The above-mentioned input charging data is used to indicate the input charging status of the built-in battery by the external power source detected by the food temperature probe; the input charging data includes second charging data, a stop charging mark and a charging description, wherein the second charging data may include the charging voltage, charging time, charging amount, etc. of the battery.

[0108] Among them, the wake-up working status data is used to indicate the sensor status data when the sensor changes from a sleep state to a working state; the output charging data detected by the repeater includes the first charging data and the charging stop time, and the wake-up working status data detected and broadcast by the sensor includes the second charging data, the charging stop mark and the power-on working time, among which, the second charging data is the charging data detected inside the sensor, which can be determined by comparing the battery power before and after charging, and the first charging data is the external output power detected inside the repeater.

[0109] Specifically, if a sensor to be matched that meets at least one matching condition is searched, the sensor to be matched is determined as the target matching sensor. The matching conditions include that the charging stop duration matches the power-on working duration, the first charging data matches the second charging data, and the charging stop flag carried.

[0110] 604. If not, replace the food temperature probe and re-match it.

[0111] Specifically, if the repeater fails to search for a food temperature probe that matches the temperature change feature, the food temperature probe is replaced and the above step 601 is executed again.

[0112] In this embodiment, environmental temperature change measures are implemented on food temperature probes to change the probe state, thereby obtaining temperature change characteristics. The temperature measurement components are matched based on the temperature change characteristics. Environmental temperature change measures for each food temperature probe are flexibly formulated according to the number of food probes to be matched and the matching accuracy requirements, thereby improving the matching reliability and accuracy, avoiding interference from other sensors, and reducing the collision probability of large-scale matching. The system is suitable for automated pairing of sensors and repeaters in large-scale production, thereby reducing labor costs and improving pairing efficiency.

[0113] In the end user scenario, there is a need for multiple sensors to monitor environmental parameters. At this time, the repeater and the sensor match also have interference from multiple sensors. Figure 5 The repeater is the execution subject, see Figure 7 An embodiment of the sensor matching method in this application is described as follows:

[0114] 701. In response to an observation instruction, obtain a target state feature corresponding to at least one target measure, and change a sensor state when the at least one target measure is executed.

[0115] The repeater control unit obtains the observation instruction sent by the host computer through the second communication unit, and parses the observation instruction to obtain the target state characteristics.

[0116] 702. Search for a to-be-matched sensor that matches the target state feature, and determine the target matching sensor.

[0117] The repeater control unit obtains the sensor state data broadcasted by the to-be-matched sensor through the first communication unit, determines whether the sensor state data carries the target state feature, and if so, determines the to-be-matched sensor as the target matching sensor.

[0118] In this embodiment, during pairing, the repeater obtains a target state feature corresponding to at least one target measure, and searches for a sensor to be matched that matches the target state feature, thereby avoiding interference from other sensors and improving the pairing efficiency of the sensors.

[0119] The sensor component matching method in this application is described above. The sensor component matching device in this application is described below. Figure 8 , an embodiment of the sensor assembly matching device in the present application includes:

[0120] A processing module 801 is used to execute at least one target measure of changing the sensor state on the to-be-matched sensor to obtain a target state feature;

[0121] The matching module 801 is used to determine the paired sensor assembly in response to the observation instruction when the repeater searches for a sensor to be matched that matches the target state feature.

[0122] In this embodiment, by executing at least one target measure of changing the sensor state on the sensor to be matched, the sensor state is changed. By observing one or more change factors during pairing, sensor component matching can be achieved, avoiding interference from other sensors. This is suitable for automated pairing of sensors and repeaters in large-scale production, reducing labor costs and improving pairing efficiency.

[0123] See also Fig. 9 Another embodiment of the sensor assembly matching device in the present application includes:

[0124] A processing module 801 is used to execute at least one target measure of changing the sensor state on the to-be-matched sensor to obtain a target state feature;

[0125] The matching module 802 is used to determine the paired sensor assembly in response to the observation instruction when the repeater searches for a sensor to be matched that matches the target state feature.

[0126] Optionally, the processing module 801 includes: a charging state changing unit 8011, configured to execute charging state changing measures on the to-be-matched sensor to obtain charging state change characteristics.

[0127] The charging state changing unit 8011 is specifically used to: alternately charge and stop charging the matching sensor, and encode the charging state and the stop charging state to obtain a charging state change code sequence;

[0128] The charging state change code sequence is determined as a charging state change feature.

[0129] Optionally, the matching module 802 is specifically used to: in response to the observation instruction, determine whether the repeater searches for a sensor to be matched that matches the charging state change characteristic;

[0130] If so, bind the target matching sensor corresponding to the repeater to obtain the successfully paired sensor component;

[0131] If not, replace the sensor and rematch it.

[0132] Optionally, the environmental parameter changing unit 8012 is used to execute environmental parameter changing measures on the sensor to be matched to obtain environmental parameter change characteristics.

[0133] Optionally, the matching module 802 is specifically used to: in response to the observation instruction, determine whether the repeater searches for a sensor to be matched that matches the environmental parameter change characteristics;

[0134] If yes, bind the to-be-matched sensor corresponding to the repeater to obtain the successfully paired sensor component;

[0135] If not, replace the sensor to be matched and match again.

[0136] In this embodiment, by executing charging state change measures and environmental parameter change measures on the matching sensor to change the sensor state, the target state characteristics generated based on the charging state change measures and the environmental parameter change measures have richer feature dimensions. Matching sensor components based on the target state characteristics of this embodiment can improve the reliability and accuracy of matching, avoid interference from other sensors, and reduce the collision probability of large-scale matching. It is also suitable for automated pairing of sensors and repeaters in large-scale production, which reduces labor costs and improves pairing efficiency.
