Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, system, computer equipment and storage medium for monitoring the life status of people in a confined space. Background Art

[0002] During the construction of ships and port machinery, there will be a large number of limited spaces such as cabins and box girders, in which workers perform various types of operations such as welding, grinding, spraying, electrical installation, etc. for a long time. The cabins and box girders are filled with a large amount of dangerous sources such as welding smoke, high temperature radiation, organic vapor, etc. The internal environment is harsh, which has a great impact on the health of the workers.

[0003] At present, the following methods are usually used to monitor people in confined spaces:

[0004] 1. Guardian system: The guardian system is a mandatory safety measure in national laws and regulations. It requires that all confined spaces must have a full-time guardian outside, and the guardian is required to periodically enter or contact the personnel inside the confined space to determine the status of the personnel. The disadvantage of this method is that it increases manpower. The number of confined spaces in shipbuilding and port machinery construction exceeds 100, so the number of additional people is not a few, but dozens. If a person is in danger during the guardian's window period, the best time for rescue will be missed when he is discovered.

[0005] 2. SOS equipment: The most commonly used is the human motionless alarm. If the equipment detects that the person has been in a motionless state after the person faints, an alarm can be issued. The disadvantage of this method is that some types of workers, such as welders, are often in a static state, and the probability of false alarms is very high, which can easily cause "wolf cry" over time.

[0006] 3. Other equipment: Intercom is also a widely used solution. The problem is similar. When the guardian calls the personnel, the personnel in the limited space are working most of the time. It is almost difficult to hear or interrupt the work to answer the intercom. The more serious problem is that if the operator has already shown dangerous symptoms, it is difficult to pick up the intercom.

[0007] Based on the above situation, it is urgent to develop a solution that can monitor workers in confined spaces in a timely and effective manner. Summary of the invention

[0008] The purpose of the present invention is to provide a method for monitoring the life status of personnel in a confined space to solve the problems raised in the above-mentioned background technology.

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] It should be noted that the serial numbers assigned to the components in the embodiments of the present invention, such as "first" and "second", are only used to distinguish the objects being described and do not have any order or technical meaning.

[0050] Combine the following Figure 1A method for monitoring the life status of personnel in a confined space of the present invention is described.

[0051] A method for monitoring life conditions of personnel in a confined space, comprising:

[0052] S1. Obtaining operation information of a limited space, and configuring alarm triggering conditions according to the operation information;

[0053] Specifically, in this application, confined space mainly refers to scenarios where operations are performed in cabins, such as shipbuilding and container welding. In these scenarios, there are multiple confined spaces that require operations, and each confined space can be numbered. For example, cabin No. 1, cabin No. 2, and so on. Different confined spaces perform different operations, such as welding in cabin No. 1 and spraying in cabin No. 2. The operating temperature of cabin No. 1 will be higher than that of cabin No. 2, and accordingly, the vital signs such as the breathing rate of personnel working in cabin No. 1 will be higher than that of cabin No. 2. Therefore, when configuring the alarm trigger conditions, it is necessary to crawl the operation content of the confined space and determine the threshold of the alarm condition based on the operation content.

[0054] In one embodiment, configuring the alarm triggering condition according to the job information includes:

[0055] Extract the work content and number of workers from the work information;

[0056] Determine the alarm value interval for alarm triggering according to the work content;

[0057] Determine the number of user terminals to be monitored according to the number of operators;

[0058] The alarm triggering condition is generated according to the alarm value interval and the number of user terminals.

[0059] Among them, the number of operators represents the number of user terminals that need to be monitored. Each operator will wear a user terminal, and the user terminal will obtain the operator's vital signs, such as heart rate, blood oxygen, body temperature and other vital sign parameters in real time. And transmit the acquired vital sign data to the server. In this embodiment, the alarm value can be set according to the historical data corresponding to the work content. For example, 100 vital sign data under work content A are collected as samples, and the median of the sample is taken as the middle value of the alarm interval, and then an error value is assigned on both sides of the middle value to obtain the alarm interval. The error value here can also be obtained by normally distributing the aforementioned samples, and the difference between the value in the 95% confidence interval and the middle value is the error value.

[0060] When monitoring a worker in a confined space for the first time, a ruling method can be used to determine whether the alarm triggering condition is met. That is, the heart rate weight is set to be large (a key vital sign), and the blood oxygen and body temperature weights are set to be small (non-key vital signs). The logic of the alarm is: an alarm is triggered when the heart rate is abnormal; an alarm is triggered when the heart rate is abnormal + the blood oxygen is abnormal; an alarm is triggered when the heart rate is abnormal + the body temperature is abnormal; an alarm is triggered when the heart rate is abnormal + the blood oxygen is abnormal + the body temperature is abnormal; an alarm is triggered when the blood oxygen is abnormal; an alarm is not triggered when the body temperature is abnormal; an alarm is triggered when the blood oxygen is abnormal + the body temperature is abnormal. In the present invention, the user terminal can use a 4G watch, and the monitoring terminal can use a mobile phone applet to receive the alarm information sent by the management terminal.

[0061] When any terminal of a person in the confined space reaches the alarm range, an alarm condition will be constituted, and the alarm light on the confined space will be lit.

[0062] S2. Determine the vital signs of the operator in the confined space to be monitored according to the alarm triggering condition;

[0063] S3. Performing real-time monitoring on the operator according to the vital signs to obtain vital sign parameters;

[0064] Specifically, during real-time monitoring, a data feedback instruction can be sent to the user terminal to be monitored. The user terminal will periodically send the vital signs data of the operator according to the instruction. If a user terminal fails to send the vital signs data on time, an abnormal information will be sent to the monitoring terminal. The operator of the monitoring terminal will go to the corresponding limited space to troubleshoot the problem.

[0065] S4. When any of the vital sign parameters exceeds the alarm value range, mark the vital sign as an abnormal sign;

[0066] Specifically, obtaining the weight of the abnormal physical sign, and judging whether the abnormal physical sign is a key physical sign according to the weight;

[0067] If the abnormal vital sign is a critical vital sign, then marking each of the related vital signs as abnormal;

[0068] Otherwise, the vital sign parameter associated with the vital sign is compared with the alarm value interval.

[0069] Different weights are assigned to each vital sign. The weight assignment can be based on the number of times a vital sign is abnormal when the operator has physical problems. Different weights are assigned to different times. For example, when 100 operators have physical problems, 95 have abnormal heart rates, then the weight of the heart rate is 0.95, and the number of people with abnormal body temperatures is 25, then the weight of the body temperature is 0.25. When the weight exceeds 0.75, the vital sign is a critical sign.

[0070] S5. Acquire associated vital signs associated with the abnormal vital signs, and if any of the associated vital signs is abnormal, send an alarm message to the monitoring terminal.

[0071] Specifically, historical data of other vital signs when the abnormal physical sign has been abnormal are obtained, and the vital sign with the most abnormal occurrences in the historical data is extracted as the associated vital sign.

[0072] After sending the alarm information to the monitoring terminal, the method further includes:

[0073] The real-time limited space where the abnormal operator is located is obtained, and an alarm light lighting command is sent to the real-time limited space. An alarm light is installed on each limited space, and the alarm light will light up after receiving the lighting command, and an alarm sound will be issued to attract the attention of the monitoring personnel. In the present invention, the alarm light can be a 4G alarm light, which has three modes: sound, light, and voice, and is connected to the cloud server through a 485 to 4G module, and then connected to the management end through the cloud server.

[0074] When determining the real-time limited space where the abnormal operator is located, the following methods can be used:

[0075] The terminal location information of the abnormal operator is obtained, and the terminal location information is compared with the spatial location information of each of the limited spaces, and the real-time limited space where the abnormal operator is located is determined according to the comparison result. When comparing the location information, GPS, Beidou and other satellites can be used for location positioning.

[0076] A second aspect of the present invention provides a confined space personnel life situation monitoring system, such as Figure 2 As shown, including:

[0077] The management terminal is used to obtain the operation information of the confined space, configure the alarm triggering conditions according to the operation information; determine the vital signs of the workers in the confined space to be monitored according to the alarm triggering conditions; determine whether the vital signs are abnormal, and send alarm information to the monitoring terminal according to the abnormal situation;

[0078] The user terminal is used to collect the vital sign data of the operator and send the vital sign data to the management terminal;

[0079] A monitoring terminal, used for receiving the alarm information sent by the management terminal;

[0080] The limited space terminal is used to receive the alarm light lighting instruction sent by the management terminal, and light the alarm light according to the alarm light lighting instruction.

[0081] For this application, the management end is used to analyze and process the vital signs data sent by the user terminal, which is the key to realizing the monitoring method of this application. Figure 3 As shown, the management end of this application may include:

[0082] An acquisition module 10, used to acquire operation information of a limited space;

[0083] The analysis module 20 is used to configure an alarm triggering condition according to the operation information, determine the vital signs of the operators in the limited space according to the alarm triggering condition, and monitor the operators in real time according to the vital signs to obtain vital sign parameters;

[0084] The processing module 30 is used to determine whether the vital sign exceeds the alarm value interval. If so, the vital sign is marked as an abnormal sign, and according to the state of the associated vital sign associated with the abnormal sign, whether to send an alarm message to the monitoring terminal.

[0085] In this monitoring system, one management terminal corresponds to multiple limited spaces. Figure 2 As shown, the management end corresponds to two limited spaces A and B. The workers in space A are one and two, and the workers in space B are three and four. Then, a mapping relationship is established between the user terminal of worker one and the user terminal of worker two and limited space A, and a mapping relationship is established between the user terminal of worker three and the user terminal of worker four and limited space B.
