[0057] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0058] Embodiment 1

[0059] Referring to Figure 1 , a step flowchart of a transmitter operation and maintenance method in an embodiment of the present invention is shown. As Figure 1 shown, the method is applied to a scheduling center including multiple computer rooms and multiple transmitters, and the method includes the following steps:

[0060] S1, execute a first transmission task and obtain a first transmission result, where the first transmission task is used to output medium and short wave signals;

[0061] In this embodiment, the first transmission task includes outputting medium and short wave signals through corresponding frequencies via computer rooms and transmitters; medium and short wave signals are commonly used in radio stations and are a frequently used frequency band in communication.

[0062] The first signal transmission result includes a task transmission failure result and a task poor quality result, and the first signal transmission result is judged by the reception situation of the receiving party; if the receiving party does not receive medium and short wave signals in the specified frequency band, it can be regarded as a task transmission failure result; if the medium and short wave signals received by the receiving party in the specified frequency band are not good, it can be regarded as a task poor quality result; both of these situations will result in poor communication content received by the receiving party, so it is necessary to execute a second transmission task to transmit medium and short wave signals again to ensure communication quality.

[0063] S2, based on the first signal transmission result, judge whether it is necessary to execute a second transmission task;

[0064] Including, if the first signal transmission result is a task failure result, it is necessary to execute a second transmission task; in the case where the first signal transmission result is a task failure result, it means that the communication fails and it is necessary to execute a second transmission task to transmit medium and short waves again.

[0065] If the first signal transmission result is a task poor quality result;

[0066] then obtain the frequency information when the first transmission task transmits medium and short waves;

[0067] Send the frequency information to the receiving party;

[0068] The frequency information includes the start frequency, end frequency, interval between each frequency, and the time of frequency broadcast sent by the dispatching center for medium and short wave.

[0069] The receiving party determines whether to execute the second transmission task based on the frequency information and the medium and short wave signals. It includes:

[0070] The receiving party receives the medium and short wave signals based on the frequency information;

[0071] In one embodiment, since medium and short wave signals are often used in the communication of radio stations, the receiving party can be set as a radio, which can receive medium and short wave information in common frequency bands and convert the medium and short wave information into audio signals for output.

[0072] This step is completed by a radio. The radio will be turned on regularly according to the task time. When the radio starts to work, it will perform the task of scanning each frequency. The scanning method is as follows: The system first sends the start frequency to the end frequency to the radio, and then gives the interval between frequencies, the time of frequency broadcast, etc. After receiving the instruction, the radio will perform radio reception.

[0073] During the scanning radio reception, if the sent start frequency and end frequency are (3.2 to 20.2), and the interval between each frequency is 0.2, then the radio scans 3.2, 3.4, 3.5... up to 20.2. When scanning to the specified frequency, it judges whether there is a task at this moment according to the system instruction. If there is, it will perform radio reception; if not, it will skip this frequency. Thus, it can ensure that all medium and short wave signals sent by the transmitters can be received and it is not easy to cause omissions.

[0074] Store the medium and short wave signals as audio signals;

[0075] Extract the noise signals from the audio signals;

[0076] Based on the noise signals, obtain the signal-to-noise ratio value; Noise refers to the noise in the audio signal, and the signal-to-noise ratio refers to the ratio of the signal to the noise in an electronic device or electronic system; By quantifying the signal-to-noise ratio, the signal-to-noise ratio value can be obtained.

[0077] Obtain the scoring threshold;

[0078] The scoring threshold is set according to the requirements for communication quality. For example, setting it lower indicates higher requirements for communication quality, and setting it higher indicates that the requirements for communication quality can be relaxed.

[0079] Based on the scoring threshold and the signal-to-noise ratio value, score the task quality of the first transmission task;

[0080] If the signal-to-noise ratio value is greater than the scoring threshold, the task quality of the first transmission task meets the standard, and there is no need to execute the second transmission task;

[0081] If the signal-to-noise ratio value is less than the scoring threshold, the task quality of the first transmission task does not meet the standard, and it is necessary to execute the second transmission task.

[0082] If the signal-to-noise ratio value is greater than the scoring threshold, it indicates that in this communication, the requirement for communication quality is relatively low, and there is no need to execute the second transmission task. The current communication quality is sufficient to meet the quality requirements.

[0083] If the signal-to-noise ratio value is less than the scoring threshold, it indicates that in this communication, the requirement for communication quality is relatively high, and it is necessary to execute the second transmission task. The current communication quality is not sufficient to meet the quality requirements. By quantifying the signal-to-noise ratio, the control of communication quality can be more accurate, so as to judge whether it is necessary to execute the second transmission task to improve communication quality.

[0084] S3, if so, obtain the computer room information of multiple computer rooms and the transmitter information of multiple transmitters;

[0085] In one embodiment, the computer room information of multiple computer rooms is obtained by setting multiple sensors inside each computer room.

[0086] Among them, the sensors for obtaining computer room information include smoke sensors, temperature sensors, and humidity sensors;

[0087] Through the multiple sensors set, the smoke concentration information, temperature information, and humidity information inside the computer room, that is, the computer room information, can be obtained in real time; and the multiple sensors are all connected to the corresponding processor through a wired network or a wireless network, and the processor can process the computer room information for subsequent use in the method mentioned in this embodiment.

[0088] In one embodiment, obtaining the transmitter information of multiple transmitters includes:

[0089] Set multiple sensors; among them, the sensors set include device status acquisition sensors, power information acquisition sensors, current sensors, voltage sensors, temperature sensors, and humidity sensors;

[0090] Through the multiple sensors set, the device status information, power information, current information, voltage information, temperature information, and humidity information of the transmitter, that is, the transmitter information, can be obtained.

[0091] Moreover, common sensors available on the market can be used for the current sensor, voltage sensor, temperature sensor, and humidity sensor. However, there are no conventional sensors for device status information and device power information. Therefore, in this embodiment, the device status acquisition sensor and the power information acquisition sensor need to receive the medium and short wave signals output by multiple transmitters and analyze the medium and short wave signals to obtain the device status information and device power information, so as to achieve the effect of acquiring the device status information and device power information. Among them, the device status information includes whether it is working, and the device power information includes whether the output power effect of the device meets the standard.

[0092] S4. Based on the computer room information and transmitter information, select a transmitter and a computer room to perform the second transmission task.

[0093] The transmitter information also includes historical score data and task data; both the historical score data and the task data are data obtained from performing the first transmission task. In one embodiment, the transmission situations of the transmitter in the past 100 transmissions are analyzed to obtain these two data, so as to accurately judge the execution situation of the transmitter for the corresponding task, and help select the optimal transmitter to perform the current medium and short wave signal transmission task.

[0094] The selecting a transmitter and a computer room to perform the second transmission task based on the computer room information and transmitter information includes:

[0095] Based on the device status information, filter out multiple idle transmitters that are currently in an idle state;

[0096] Obtain the historical score data and task data of the multiple idle transmitters;

[0097] Based on the historical score data, the task data, and the transmitter information, perform a priority ranking on the multiple idle transmitters;

[0098] Based on the computer room information, perform a priority ranking on the multiple computer rooms;

[0099] Select the transmitter and computer room with the highest ranking to perform the second transmission task.

[0100] Among them, the performing a priority ranking on the multiple idle transmitters based on the historical score data, the task data, and the transmitter information includes:

[0101] Set weights for the historical score data, the task data, and the transmitter information respectively;

[0102] Score the historical score data, the task data, and the transmitter information to obtain the historical score data score, the task data score, and the transmitter information score;

[0103] In one embodiment, the weight ratio of historical score data, task data, and transmitter information is 6:3:1.

[0104] Based on the weights and the scores of the historical score data, task data, and transmitter information, obtain the total scores of the multiple idle transmitters;

[0105] Based on the total scores of the multiple idle transmitters, perform priority sorting on the multiple idle transmitters.

[0106] Among them, the performing priority sorting on the multiple computer rooms based on the computer room information includes:

[0107] Based on the smoke concentration information, temperature information, and humidity information in the computer room information, classify the multiple computer rooms, and the classification includes excellent, good, medium, and poor;

[0108] In this embodiment, each parameter in the computer room information needs to define the numerical range of 4 levels. For example: excellent temperature is: 20°C - 26°C, good temperature is: 27°C - 30°C, medium temperature is: 31°C - 35°C, and poor temperature is: 36°C and above. Through classification, the usage priorities of multiple computer rooms can be sorted, so as to select the best computer room among multiple computer rooms to execute the second transmission task.

[0109] Based on the classification of excellent, good, medium, and poor, perform priority sorting on the multiple computer rooms.

[0110] In this embodiment, after the first transmission task is executed, if it is determined that the communication quality of the first transmission task is insufficient, the second transmission task is immediately performed. When the second transmission task is executed, first select the transmitter with the highest priority. This transmitter must be the most suitable idle transmitter for the current transmission task among the multiple idle transmitters, and then select the computer room with the highest priority to transmit the medium and short wave signals. By adopting the above method, the best transmission scheme can be generated among multiple computer rooms and multiple transmitters to maximize the communication quality of the transmission task, thereby achieving the effect of improving the transmission quality; and during the scheduling process of the transmitter and the computer room, the device only needs to execute the above method to schedule the transmitter and the computer room, without the need for manual scheduling intervention, thereby liberating the labor force and improving the allocation rules.
