The related content in the alternative is taken as an invention point of the disclosure, thereby solving the second technical problem that the background technology is difficult to alarm partial abnormal conditions. Factors that cause difficulty in alerting to a partial abnormal situation are often as follows: the closed type jet type fuse only considers the abnormal situation of the fuse blowing, and other abnormal situations (such as line power failure) are difficult to identify. If the above factors are solved, the effect of warning partial abnormal conditions can be achieved. To achieve this effect, the signal acquisition and processing device of the present disclosure includes a current signal acquisition and processing circuit, an electric field sensor, an electric field signal acquisition and processing circuit, and a photosensor. Specifically, the signal acquisition processing device that the closed type jet-type fuse intelligent monitoring equipment of this disclosure included can gather current signal, electric field signal and optical signal. Thus, in addition to the case of detecting whether the fuse is blown or not based on the optical signal, the case of detecting whether the line is out of power based on the current signal or the electric field signal can be detected. Therefore, a warning can be given to a part of the abnormal situation.

In some embodiments, the light emitter 2141 is electrically connected to the main control chip 22 for: the optical modulation signal information sequence transmitted from the main control chip 22 is received, and the optical modulation signal information sequence is transmitted to the optical receiver 2141.
The optical receiver 2141 is electrically connected to the main control chip 22, and is configured to: the optical modulation signal information sequence transmitted by the optical transmitter 2141 is received, and the optical signal information sequence is transmitted to the main control chip 22.
The light emitter 2141 may be an infrared emitter tube (e.g., an HIR204C emitter tube). The optical receiver 2142 may be an integrated infrared receiver (e.g., IRM-3638M receiver). The optical receiver 2142 may receive the optical modulation signal information sequence transmitted by the optical transmitter 2141 through a wireless communication manner. The light emitter 2141 and the light receiver 2142 may be mounted in a counter-incident manner at the bottom of a closed type jet fuse. Therefore, after the fuse wire of the closed type jet-type fuse is blown, the fuse carrying piece in the closed type jet-type fuse can pop up from the inside of the closed type jet-type fuse, and communication between the light emitter and the light receiver can be blocked, so that whether the fuse wire of the closed type jet-type fuse is blown or not can be identified.
The disclosure also provides a closed type jet fuse intelligent monitoring method, which is applied to the closed type jet fuse intelligent monitoring device of each embodiment, as shown in fig. 5, and a flowchart of some embodiments of the closed type jet fuse intelligent monitoring method according to the disclosure is shown. The method may comprise the steps of:
in step 501, the state sensing device collects the current signal information sequence of the primary line, and sends the current signal information sequence to the signal collection processing device.
In some embodiments, the state sensing device may collect a current signal information sequence of the primary line, and send the current signal information sequence to the signal collection processing device.

Step 502, a signal acquisition processing device acquires an electric field signal information sequence of a primary line.
In some embodiments, the signal acquisition processing device may acquire the electric field signal information sequence of the primary line.
In step 503, the signal acquisition processing device generates an optical signal information sequence in response to receiving the optical modulation signal information sequence sent by the main control chip.
In some embodiments, the signal acquisition processing device may generate the optical signal information sequence in response to receiving the optical modulation signal information sequence sent by the main control chip. The signal acquisition and processing device may include, but is not limited to: the device comprises a current signal acquisition and processing circuit, an electric field sensor, an electric field signal acquisition and processing circuit and an optical sensor. The light sensor may include, but is not limited to: an optical transmitter and an optical receiver.
In practice, firstly, the light transmitter responds to the light modulation signal information sequence sent by the main control chip, and the light modulation signal information sequence can be transmitted to the light receiver in a wireless communication mode. Then, in response to receiving the optical modulation signal information transmitted by the optical transmitter, the optical receiver may determine the optical signal information by: in a first step, a first preset optical signal value is determined as optical signal information in response to determining that the optical transmitter and the optical receiver satisfy a first communication condition. And a second step of determining a second preset optical signal value as the optical signal information in response to determining that the optical transmitter and the optical receiver satisfy the second communication condition. And a third step of determining a third preset optical signal value as the optical signal information in response to determining that the optical transmitter and the optical receiver satisfy a third communication condition. Finally, the optical receiver may determine the determined respective optical signal information as an optical signal information sequence.
Here, the light modulation signal information in the light modulation signal information sequence may be first modulation information or second modulation information. The first modulation information may characterize a bit (e.g., 0). The second modulation information may characterize a bit (e.g., 1). The optical modulation signal information sequence may be a preset number of modulation information sequences. The modulation information sequence may be first modulation information, second modulation information, first modulation information, and second modulation information. For example, the preset number may be 36. The initial value of the optical signal information in the optical signal information sequence may be a preset initial optical signal value. The first communication condition may be that there is an occlusion between the optical transmitter and the optical receiver. The second communication condition may be that there is no shielding between the optical transmitter and the optical receiver, and normal communication is possible. The third communication condition may not satisfy the first communication condition and the second communication condition. For example, the preset initial optical signal value may be 0x3F. The first preset optical signal value may be 0x3F. The second preset optical signal value may be 0x2A. The third preset optical signal value may be a value other than the first preset optical signal value and the second preset optical signal value described above. Here, the arrangement order of the optical modulation signal information in the optical modulation signal information sequence may be a time order. The order of arrangement of the optical signal information in the optical signal information sequence may be a time order.
At this time, since the optical transmitter and the optical receiver are installed at the bottom of the closed type injection fuse in a correlation manner, when the fuse wire in the closed type injection fuse is blown, the fuse carrying element in the closed type injection fuse can pop out from the inside of the closed type injection fuse, so that communication between the optical transmitter and the optical receiver can be blocked, that is, when a first communication condition occurs, the optical receiver cannot receive the optical modulation signal information emitted by the optical transmitter, so that the optical signal information of the optical receiver can be a first preset optical signal value equal to a preset initial optical signal value.
In addition, when the closed type injection fuse communicates normally, that is, when the second communication condition occurs, the optical receiver may receive the optical modulation signal information transmitted from the optical transmitter, and then may determine the second preset optical signal value as the optical signal information.

The technical content in step 506 is taken as an invention point of the embodiment of the present disclosure, and solves the third technical problem mentioned in the background art, namely that the warning of the partial abnormal situation is difficult. The factors that make it difficult to alert to a partial anomaly are often as follows: the current signal is converted into a current digital signal through an analog-to-digital conversion algorithm, and the acquired current signal is possibly abnormal, so that the accuracy of the current digital signal after analog-to-digital conversion is low, and the accuracy of the identified abnormal situation is low. If the above factors are solved, the effect of warning partial abnormal conditions can be achieved. To achieve this, first, the above-described current modulation signal information sub-sequence is subjected to a filtering process to generate a current filtered signal information group. And secondly, filtering the electric field modulation signal information sub-sequence corresponding to the current modulation signal information sub-sequence to generate an electric field filtering signal information group. Then, the reference voltage signal information sub-sequence corresponding to the current modulation signal information sub-sequence is subjected to filtering processing to generate a voltage filtering signal information group. Thus, the current modulation signal information subsequence, the electric field modulation signal information subsequence and the reference voltage signal information subsequence can be subjected to filtering processing, and the maximum and minimum current signals, the electric field signals and the reference voltage signals can be removed, so that the collected abnormal current signals, the collected abnormal electric field signals and the collected abnormal reference voltage signals can be removed. Then, the above-described current filtered signal information group is subjected to a conversion process to generate a current converted signal value. Then, the electric field filtered signal information set is subjected to conversion processing to generate an electric field converted signal value. And then, determining an average value of the voltage filtering signal values included in the voltage filtering signal information group as a target voltage signal value. Finally, a target current signal value and a target electric field signal value are generated based on the current transformation signal value, the electric field transformation signal value, and the target voltage signal value. Thus, the current filtered signal and the electric field filtered signal can be converted into a target current signal value (current digital signal) and a target electric field signal value (electric field digital signal) with high accuracy according to fourier transform and a reference voltage signal. Therefore, the more accurate abnormal condition can be identified according to the more accurate target current signal value, the target electric field signal value and the optical signal information. Thus, a warning can be given to a part of the abnormal situation.
