Description

Technical Field

[0001] The invention relates to the field of skill assessment, and in particular to an auxiliary method and device based on the business ability assessment of emergency repair service agents. Background Art

[0002] The power emergency repair service agent is an important window position in the power industry. He or she has a huge impact on indicators such as the dispatch of emergency repair tasks, emergency repair punctuality, emergency repair efficiency, and customer satisfaction. The skill level of the personnel in this position directly affects the quality of power supply services. Scientific assessment of the business capabilities of the personnel in this position is an effective means to improve the technical level of the personnel in this position. However, due to the particularity of the position of customer service agents, it is difficult for general simulation training software to fully and objectively reflect the technical level of personnel. Emergency repair service agents need to judge the type and location of the fault, as well as the importance of the fault, at the first time. This requires scientific evaluation measures for the tension of personnel in emergency response. If the evaluation is based solely on the accuracy of the emergency repair work order, it is difficult to grasp the psychological tension of the personnel at that time, and thus it is impossible to truly reflect the comprehensive business ability and job competence of the emergency repair service agents. The psychological tension is the most effective factor in evaluating the emergency response ability of personnel. In the existing technology, there are technologies that use human blood pressure and heart rate to test the tension. However, these technologies all require the arrangement of sensors on the human body, which not only increases the psychological burden of personnel, but also makes on-site operation very inconvenient. In addition, blood pressure and heart rate can be controlled by taking drugs. In this way, when evaluating personnel's job skills, the heart rate and blood pressure can be reduced by taking sedatives or antihypertensive drugs, creating an illusion of being calm and not nervous. Therefore, there is an urgent need for an auxiliary method and device that can simply and effectively and scientifically evaluate the psychological tension of emergency repair service agents at work.

[0003] The "non-contact emotion detection method and device" disclosed in the Chinese patent literature has a publication number of CN106264568B. The invention provides a non-contact emotion detection method and device, which relates to the field of emotion detection technology. The method comprises: collecting video information containing the detected human body and the heat map / hot spot area map of the detected human body through a camera and an infrared sensor respectively; identifying the video information and the heat map / hot spot area map to obtain the human body characteristic data of the detected human body; correlating and analyzing the human body characteristic data with a deep learning engine to obtain the tension level of the detected human body; and outputting the result of the human body tension level obtained by the deep learning engine analysis. The present invention combines intelligent sensing technology, machine vision, and deep learning engine analysis to interpret the human body characteristic data from the collected video and other data in a short time, and finally analyzes the danger index and psychological tension level of the detected person, providing the detection personnel with an effective reference for predicting and preventing the occurrence of danger. However, the illusion caused by taking sedatives or antihypertensive drugs to reduce heart rate and blood pressure cannot be ruled out. Summary of the invention

[0004] The present invention solves the problem of misjudgment of personnel's job skills assessment caused by lowering heart rate and blood pressure by taking sedatives or antihypertensive drugs, and proposes an auxiliary method and device based on the business ability assessment of emergency service agents. By detecting the keyboard keystroke pressure value, the distance value between the human chest and the proximity sensor, and the carbon dioxide value within a period of time, and after comprehensive data processing and conversion, a voltage signal is obtained and displayed. The scheme of the present invention can scientifically measure the tension level of personnel in the agent's job simulation operation assessment or in the formal job state, and the operation is also relatively convenient.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: an auxiliary method based on the business ability assessment of emergency repair service agents, comprising the following steps:

[0006] S1, detecting the pressure values ​​of several keyboard keystrokes within a timing period;

[0007] S2, detecting the distance value between the human chest and the proximity sensor within the timing period;

[0008] S3, detecting the carbon dioxide value within the timing period;

[0009] S4, performing data processing on the pressure value, distance value and carbon dioxide value obtained by the detection respectively;

[0010] S5, converting the processed data into a signal of the same proportion. In the present invention, the speed of body swinging when a person is nervous, the pressure of typing on the keyboard, and the carbon dioxide discharged by breathing will all change, and the sensor detection and signal extraction analysis are performed. After the analysis is completed, the tension of the agent can be scientifically measured. Since it uses a variety of sensors and the interaction of information from various aspects from physics to chemistry, it can more objectively reflect the anxiety and tension of personnel at work. In addition, the technical solution proposed by the present invention can truly reflect the comprehensive business capabilities and job competence of the agent. The agent cannot change the test results through drugs, and the credibility is high.

[0011] Preferably, the processing method of the pressure value is as follows: within a timing cycle, the pressure values ​​obtained from two consecutive tests are subtracted and then divided by the total number of keystrokes within the time period to obtain a value A. In the present invention, the value A is used to reflect the human body tension signal transmitted through the cerebellum and limbs. When typing on the keyboard, if the pressure value of each tap is different, it means that the degree of psychological tension or anxiety of the person is different. When the psychological activity is peaceful, the force of tapping the keyboard is uniform, and the number of times of heavy and light tapping is small. On the contrary, there is obviously an uneven force phenomenon. Compared with the respiratory heart rate detection, it can more intuitively detect the tension of the human body under special stress state.

[0012] Preferably, the distance value is processed as follows: the detected distance value is derived with respect to time, and when the derived value is greater than 0.2 meters per second, it is recorded as one time, and the number of times is accumulated within a timing cycle and multiplied by the conversion coefficient to obtain the value B. In the present invention, when the human body is nervous, the body will have involuntary high-frequency jitter or swing. By testing the swing rate (derivative of the swing amplitude with respect to time), the involuntary body swing can be effectively measured, thereby cooperating with the change in the value of the force of typing on the keyboard to more accurately detect the degree of human tension.

[0013] Preferably, the carbon dioxide value is processed by establishing a model of carbon dioxide concentration and time within a timing period, taking the maximum carbon dioxide concentration and the corresponding time for storage, and obtaining the maximum carbon dioxide concentration C. In the present invention, the carbon dioxide concentration directly reflects the human body's metabolic rate.

[0014] An auxiliary device based on the business ability assessment of emergency repair service agents, suitable for the above-mentioned auxiliary method based on the business ability assessment of emergency repair service agents, characterized in that it includes a thin plate, the thin plate is connected to a box body, a plurality of carbon dioxide sensors are arranged above the box body, a proximity sensor and a digital display are arranged on the side of the box body away from the thin plate, a signal processing unit is arranged inside the box body, and a keyboard keystroke pressure sensor is arranged on the thin plate. When the device of the present invention is used, it is placed on the desktop of the computer keyboard of the assessed agent close to the human body, wherein the thin plate of the device of the present invention is inserted into the groove arranged below the keyboard, that is, the keyboard keystroke pressure sensor is inserted into the bottom of the keyboard and fixed, so that when the agent types, the pressure and pressure change signal of each keyboard stroke can be collected, the carbon dioxide sensor is arranged above the box body, and is aimed at the human head; the proximity sensor points to the human chest, and is used to detect the human body swing information, and the arrangement of the sensor is conducive to the detection and collection of information.

[0015] Preferably, the signal input end of the signal processing unit is connected to the signal output ends of the keyboard keystroke pressure sensor, the proximity sensor and several carbon dioxide sensors respectively, and the signal output end of the signal processing unit is connected to the digital display. In the present invention, multiple carbon dioxide sensors are provided to prevent the failure of continuous detection of carbon dioxide after a single one is damaged. The signal processing unit is the overall control center of the device of the present invention, and the digital display includes a voltage indication number, which can accurately display the voltage signal at the moment.

[0016] Preferably, two grooves are formed at the bottom of the box body, and hinge shafts are installed inside the grooves. The hinge shafts are connected to the support plates, and the support plates are hinged to the edges of the grooves. In the present invention, adjustable support plates are provided at both ends of the bottom of the box body. The support plates rotate with the hinge shafts, and the support plates at both ends can flexibly adjust the height of the device, so that the cooperation with the keyboard is more stable, and the detection result is more accurate.

[0017] Preferably, the keyboard keystroke pressure sensor is a thin film sensor. In the present invention, this sensor can meet the requirements of keystroke pressure detection.

[0018] The beneficial effects of the present invention are:

[0019] 1. The scheme of the present invention makes a scientific evaluation of the degree of tension of personnel in emergency response. When a person is nervous, the acceleration of body swing, the force of typing on the keyboard, and the carbon dioxide discharged by breathing will all change.

[0028] Example:

[0029] This embodiment proposes an auxiliary method based on the business ability assessment of emergency service agents, which mainly includes the following steps: Step 1: Detect the pressure values ​​of multiple keyboard keystrokes within a timing period; specifically, use a keyboard keystroke pressure sensor to detect and obtain data, and a thin film sensor is used in this embodiment.

[0030] Step 2: Detect the distance between the chest of the person to be tested and the sensor within a timing period; specifically, use a proximity sensor to complete the distance detection.

[0031] Step 3: Detect the carbon dioxide value exhaled by the human body within the timing period; specifically use a carbon dioxide sensor.

[0032] Step 4. After the detection and data acquisition of steps 1 to 3, the detected data are processed. First, the pressure value is processed. In a timing cycle, the last pressure value is subtracted from the previous pressure value and the absolute value is taken. Then, the total number of keystrokes during this period is removed. The obtained value is saved in the timing cycle and recorded as value A. Secondly, the distance value is also processed accordingly. The value obtained after the detection is first saved and then derived, specifically the time derivative. When the derivative value is greater than 0.2 m / s, it will be recorded as 1 time. The number of times is counted in a timing cycle, and the number of times is multiplied by the conversion coefficient to obtain the final value B. Finally, in this embodiment, a model is established based on the concentration value measured by the carbon dioxide sensor and the corresponding time, wherein the maximum concentration of carbon dioxide in the cycle is inspected and saved to obtain value C.

[0033] Step 5: Sum the three processed values ​​and convert them into proportional signals, which can be observed in the digital display.

[0034] In the present invention, the value A is used to reflect the human body tension signal transmitted through the cerebellum and limbs. Similarly, when typing on the keyboard, if the pressure value of each tap is different, it means that the degree of psychological tension or anxiety of the person is different. When the psychological activity is calm, the force of tapping the keyboard is uniform, and the number of times of heavy and light tapping is small. Otherwise, there is obviously uneven tapping force. Compared with respiratory heart rate detection, it can more intuitively detect the tension degree of the human body under special stress state.

[0035] In the present invention, when a human body is nervous, the body will experience involuntary high-frequency shaking or swinging. By testing the swing rate (derivative of the swing amplitude with respect to time), the involuntary body swing can be effectively measured, thereby cooperating with the change in the force of typing on the keyboard to more accurately detect the degree of tension in the human body.

[0036] In the present invention, the concentration of carbon dioxide directly reflects the metabolic rate of the human body. The algebraic sum of the values ​​of A, B, and C in the same timing cycle is calculated, and the value is converted into a signal of the same proportion, which can intuitively reflect the tension of the human body in a period of time. The larger the value, the higher the psychological tension of the person.

[0037] The present invention also proposes an auxiliary device based on the business ability assessment of the emergency repair service agent, which is applicable to the above method, referring to Figure 1 , Figure 2 and Figure 3 The device mainly includes a thin plate and a box body, which are connected to each other. A plurality of carbon dioxide sensors 3, a proximity sensor 2 and a digital display 5 are distributed on the box body. In this embodiment, three carbon dioxide sensors 3 are arranged above the box body, while the proximity sensor 2 and the digital display 5 are arranged on the side of the box body away from one end of the thin plate. At the same time, a signal processing unit 4 is arranged in the box body, and a keyboard keystroke pressure sensor 1 is arranged on the thin plate, specifically embedded in the thin plate.

[0038] refer to Figure 2 The signal output ends of the keyboard keystroke pressure sensor 1, the proximity sensor 2 and the three carbon dioxide sensors 3 are all connected to the signal input end of the signal processing unit 4. The output end of the signal processing unit 4 is connected to the digital display 5. The digital display 5 includes a voltage indication number and other indications.

[0039] refer to Figure 3 , Figure 4 and Figure 5 A support plate 6 is provided below the box body. The support plate 6 is hinged to the edge of the groove, specifically connected by a hinge shaft 8. The hinge shaft is installed inside the groove 7. Two grooves 7 are symmetrically arranged below the box body. One end of the groove 7 is semicircular and the other end is rectangular. An inclined surface is provided on one side of the support plate 6 to facilitate the support of the support plate 6 to the ground after it is flipped over.

[0040] In the present invention, a plurality of carbon dioxide sensors are provided to prevent the failure of continuous carbon dioxide detection after a single sensor is damaged. The signal processing unit is the overall control center of the device of the present invention. The digital display includes a voltage indication number, which can accurately display the voltage signal at the moment.

[0041] In the present invention, adjustable support plates are provided at both ends of the bottom of the box body. The support plates rotate with the hinge shaft, so that the support plates at both ends can flexibly adjust the height of the device, thereby making the cooperation with the keyboard more stable and making the detection result more accurate.

[0042] The dynamic use process of the device in the present invention: when in use, it is placed on the desktop of the computer keyboard of the evaluated agent close to the human body, wherein the thin plate of the device of the present invention is inserted into the groove below the keyboard, that is, the keyboard keystroke pressure sensor is inserted into the bottom of the keyboard and fixed. Since the height of each keyboard is inconsistent, after the thin plate is aligned with the groove of the keyboard, the support plate arranged under the box body of the device is flexibly flipped and adjusted to an appropriate height. After the device is installed, the thin plate fits the height of the groove of the keyboard. In this way, when the agent types, the keyboard keystroke pressure sensor 1 on the thin plate can collect the pressure and pressure change signal of each keyboard stroke. The carbon dioxide sensor 3 is arranged above the box body and is aimed at the human head; the proximity sensor 2 points to the human chest and is used to detect the human body swing information. The setting of the sensor is conducive to detecting and collecting information.

[0043] The present invention cleverly utilizes the changes in the speed of body swing, the force of typing and the carbon dioxide discharged by breathing when a person is nervous. Through the detection of sensors and signal extraction and analysis, the above information is analyzed, and the degree of nervousness of personnel in the simulated operation assessment of the agent position or the formal post state can be measured more scientifically. Because it uses a variety of sensors, the interaction of information from various aspects from physics to chemistry can more objectively reflect the anxiety and nervousness of personnel when working at the post. Compared with the prior art, the present invention can truly reflect the comprehensive business ability and job competence of the repair service agent, and the personnel cannot change the test results through drugs. In the prior art, there are technologies that use human blood pressure and heart rate to test the degree of nervousness. However, these technologies all require the arrangement of sensors on the human body, which not only increases the psychological burden of personnel, but also makes on-site operation very inconvenient. In addition, blood pressure and heart rate can be controlled by taking drugs. In this way, when the personnel are evaluated for their job skills, the heart rate and blood pressure can be reduced by taking sedatives or antihypertensive drugs, creating an illusion of being calm and not nervous. The technical solution proposed by the present invention cannot affect the detection effect through drugs, and it does not require the arrangement of sensors on the human body. In addition, the cost is extremely low. The sensors used in the present invention are all common sensors in the industrial or civilian fields, and the price is about tens of yuan. The existing technology uses blood pressure or heart rate detection, which requires the use of special medical sensors, which cost hundreds of yuan or more and are difficult to promote and apply.

[0044] The above embodiments are further elaborations and illustrations of the present invention for ease of understanding, and are not limitations of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
