All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, a flow chart of a method for measuring heat and temperature of an electrical device connector according to an embodiment of the present invention includes S1-S5:

s1, generating a digital twin space corresponding to a target area, wherein the digital twin space comprises electric equipment which needs to be monitored by a user and a power supply circuit for supplying power to each electric equipment, distributing a corresponding nut temperature sensor for each electric equipment, and adding a corresponding sensor code.

In order to display the power system in the target area, the digital twin space corresponding to the target area is generated, and corresponding data is displayed through the digital twin space.

The digital twin space comprises electric equipment which needs to be monitored by a user and a power supply circuit for supplying power to each electric equipment, and meanwhile, the scheme can allocate a corresponding nut temperature sensor for each electric equipment and add a corresponding sensor code. The sensor codes are, for example, A1, A2, etc., but may be other types, and the present embodiment is not limited thereto.

It will be appreciated that when the target area is large, the digital twin space of the target area may be stitched according to a plurality of digital twin modules. For example, the target region may be split into 3 region tiles.

It should be noted that the digital twin module at least includes an electrical device that a user needs to monitor, and a power supply line that supplies power to all the electrical devices, where the electrical device is a power device such as a transformer.

S12, dividing the digital twin space into a plurality of sub-twin spaces according to partition information of the user, and obtaining associated equipment corresponding to each sub-twin space according to the associated modules added to the sub-twin spaces by the user.

The digital twin space can be divided into a plurality of sub-twin spaces by combining partition information of the user, and the sub-twin spaces can correspond to a room for storing electrical equipment and also can correspond to the electrical equipment and can be divided by combining the requirements of the user.

It is worth mentioning that in some cases, some electrical devices may be associated. For example, some electrical devices are stored in the same space (e.g., a room), and when one electrical device is overheated, it may affect other electrical devices in the same space, so that a plurality of electrical devices in one space (e.g., a sub-twin space) may be used as the associated devices. For another example, some electrical devices may share a control switch, such as electrical device a and electrical device B share control switch 1, and when control switch 1 is turned off, then both electrical device a and electrical device B may be powered off, and electrical device a and electrical device B may be associated devices.

S13, distributing a corresponding nut temperature measuring sensor for each electrical device, generating a sensor code corresponding to each nut temperature measuring sensor, and enabling each nut temperature measuring sensor to correspond to the corresponding electrical device in the digital twin space.

According to the scheme, a corresponding nut temperature measuring sensor is allocated to each electrical device, and a sensor code corresponding to each nut temperature measuring sensor is generated at the same time, and it is required to be noted that each nut temperature measuring sensor needs to correspond to the corresponding electrical device in the digital twin space.

S2, acquiring equipment attributes of each piece of electrical equipment, generating a threshold condition corresponding to the electrical equipment according to the equipment attributes, and generating sensor configuration information corresponding to each nut temperature sensor according to the threshold condition and the attributes of the nut temperature sensors.

It should be noted that, electrical devices are different, and corresponding device attributes are also different. The equipment attributes include rated working currents, and it can be understood that when the rated working currents are different, corresponding heating judgment conditions are also required to be different so as to improve judgment accuracy.

The scheme can combine the equipment attribute to generate a threshold condition corresponding to the electrical equipment.

Meanwhile, the scheme can also combine the threshold condition and the attribute of the nut temperature sensor to generate sensor configuration information corresponding to each nut temperature sensor.

In some embodiments, S2 (obtaining a device attribute of each electrical device, generating a threshold condition corresponding to the electrical device according to the device attribute, and generating sensor configuration information corresponding to each of the temperature-sensing screw cap sensors according to the threshold condition and the attribute of the temperature-sensing screw cap sensor) includes S21-S23:

s21, acquiring equipment attributes of each piece of electrical equipment, wherein the equipment attributes at least comprise rated working current, and generating temperature threshold conditions corresponding to the corresponding electrical equipment according to the rated working current.

The step is to generate a temperature threshold condition corresponding to the corresponding electrical equipment in combination with the rated operating current. For example, at a rated operating current of 10A, the corresponding temperature threshold condition is 20 ℃, and at a rated operating current of 10A, the corresponding temperature threshold condition is 25 ℃.

S22, acquiring the attribute of the corresponding type of the nut temperature measuring sensor, wherein the attribute of the nut temperature measuring sensor comprises the output frequency of a DC-DC module and the function relation between the acquired voltage and the temperature.

It should be noted that the nut temperature sensor is directly connected to the corresponding electrical equipment, and is powered by the power supply of the electrical equipment. The property of the nut temperature sensor comprises two aspects, wherein the first aspect is the output frequency of the DC-DC module, and the second aspect is the function relation between the acquisition voltage and the temperature.

For the attributes of the first aspect, referring to fig. 2, since the nut temperature sensor is connected to the electrical device, it has no own power source and needs to be charged and discharged. When the power is off, a process of charging the capacitor is carried out, and when the power is on, a process of discharging the capacitor is carried out. It can be understood that, when the power is off, the data collection and transmission can not be performed by the nut temperature sensor, and when the power is on, the data collection and transmission can be performed by the nut temperature sensor, that is, the nut temperature sensor obtains the collected voltage through interval, the interval of the collected voltage is related to the output frequency of the DC-DC module, for example, when the output frequency of 5S is adopted, the corresponding interval time is 5S, that is, the data is not transmitted by 5S, and the output frequency attribute of the DC-DC module can be obtained to determine whether the data transmission dimension is abnormal or not.

For the attribute of the second aspect, as the temperature of the nut temperature measuring sensor is judged by utilizing the functional relation between the acquired voltage and the temperature, after the temperature threshold condition is obtained by combining the attribute of the electrical equipment, the corresponding threshold voltage can be converted through the functional relation, so that the subsequent judgment is more accurate.

After the temperature threshold condition is obtained, the scheme extracts a temperature edge value in the temperature threshold condition, wherein the temperature edge value can be the maximum value in the temperature threshold condition. For example, the temperature threshold condition is 20 ℃ to 21 ℃, then the temperature margin value may be 21 ℃.

After the temperature edge value is obtained, the temperature edge value is compared with the functional relation between the acquired voltage and the temperature, and the edge electric signal corresponding to the temperature edge value is determined. For example, it is determined that the edge electrical signal corresponding to 21 ℃.

And then, when judging whether the temperature exceeds the temperature, judging by combining the calculated edge electric signals.

S232, obtaining corresponding basic transmission time according to the output frequency of the DC-DC module, obtaining standard delay time according to the network connection relation and the network connection attribute of the nut temperature sensor, and obtaining corresponding maximum transmission time according to the basic transmission time and the standard delay time.

It should be noted that the output frequencies of the DC-DC modules may be different, and the corresponding basic transmission times may be different, for example, the basic transmission time is 5S, and it is understood that the basic transmission time is an interval transmission time, that is, no data is transmitted in the 5S. Meanwhile, since the transmission of the nut temperature sensor generally adopts wireless transmission to collect data or adopts a combination of wireless and wire to transmit the collected data, some delay may exist. The scheme can calculate the corresponding maximum transmission time by combining the data of the multiple dimensions. Thereby determining whether the transmission dimension is abnormal.

In some embodiments, S232 (obtaining a standard delay time according to a network connection relation and a network connection attribute of the nut temperature sensor) includes S2321-S2323:

s2321, acquiring network connection attributes of the nut temperature sensor, wherein the network connection attributes comprise communication equipment types of the nut temperature sensor, and determining corresponding first transmission coefficients according to the communication equipment types.

When the calculation is performed, first, the scheme multiplies the first transmission coefficient by the first coefficient weight to obtain a first calculation coefficient. The first calculation coefficient is a coefficient corresponding to the type of communication equipment of the nut temperature sensor. The first coefficient weight may be preset by a worker.

The number of relay transmission devices is multiplied by the first number weight to obtain a second calculation coefficient. The second calculation coefficients are coefficients of the number dimension of the relay transmission devices, and the larger the number is, the larger the corresponding second calculation coefficients are. The first number of weights may be preset by a worker.

And multiplying all the second transmission coefficients by the second coefficient weights respectively, and adding to obtain a third calculation coefficient. The third calculation coefficient is a coefficient synthesized by each relay transmission device. The second coefficient weight may be preset by a worker.

S23232, adding the first calculation coefficient, the second calculation coefficient and the third calculation coefficient to obtain a sum of calculation coefficients, comparing the sum of calculation coefficients with a preset coefficient to obtain a time adjustment coefficient, and adjusting preset time according to the time adjustment coefficient to obtain corresponding delay time. The preset coefficient may be preset by a worker.

The delay time is calculated by the following formula,

，

wherein,,for delay time, +.>For the first transmission coefficient, < >>For the first coefficient weight, +>For the number of relay transmission devices +.>For the first quantity weight->Is->Second transmission coefficient of the relay transmission device, < >>Is->A second coefficient weight of the relay transmission device,/>for the preset coefficient, ++>Is a preset time.

In the above-mentioned formula(s),representing the first calculation coefficient,/->Representing a second calculation coefficient,/->Representing the third calculation coefficient, the larger the sum of the calculation coefficients obtained by adding the first calculation coefficient, the second calculation coefficient and the third calculation coefficient is, the higher the corresponding delay time is.

S233, generating front end configuration information of the temperature sensor for the nut according to the edge electric signal, and generating rear end configuration information of the temperature sensor for the nut according to the maximum transmission time.

It can be appreciated that there are two kinds of configuration information of the nut temperature sensor in this scheme, one is front end configuration information including an edge electric signal, and the other is back end configuration information including a maximum transmission time.

S3, acquiring power supply switches corresponding to each power supply line, and correspondingly setting sensor codes of each nut temperature sensor and switch codes of the power supply switches according to the connection relation between each power supply switch and the electrical equipment.

In order to control corresponding electrical equipment by combining judgment information, the power supply switch corresponding to each power supply circuit can be obtained, then the sensor code of each nut temperature sensor and the switch code of the power supply switch are correspondingly arranged by combining the connection relation between each power supply switch and the electrical equipment, and then the corresponding code is used for controlling.

In some embodiments, S3 (obtaining a power supply switch corresponding to each power supply line, and setting a sensor code of each nut temperature sensor to a switch code of the power supply switch according to a connection relationship between each power supply switch and an electrical device) includes S31-S32:
