second, the switch operation position repairs the pump monitor, which may cause personal injury.

In the process of repairing the booster pump by the maintenance personnel in a factory, the operation monitor closes the switch without authorization, which may cause serious personal injury.

briefly

on the morning of February 27th of a certain year, the maintenance personnel of a factory overhauled the booster pump in the water source. The work permit stopped the pump, and when the power failure measures were taken, the switch was not pulled to the "maintenance" position because the operating mechanism of the 381V handcart switch was stuck, and it was still in the "operation" position. After on-site confirmation by the work permit and the person in charge of the work, the sign "No closing with someone working" is put up and the maintenance work is started.

During the maintenance, the operation monitor visited the switch room and found that the booster pump switch was still in the "running" position. He took down the signboard without authorization and tried to pull the switch to the "maintenance" position. When the switch was pulled, the "Close" button was pressed, and the switch was closed, and the disassembled booster pump was started, and four maintenance personnel hurriedly dodged, which may cause serious personal injury.

causes and exposure problems

1. The operator seriously violated the rules and did not pull the switch to the "maintenance" position as required by the working ticket, and the switch was still in the "running" position, so it was allowed to work;

2. The person in charge of the work seriously violated the rules, knowing that the switch was still in the "running" position, and did not take measures to prevent the sudden rotation of the pump body, and agreed to start the work, which was irresponsible to the members of the working class;

3. Two people were burned by short circuit during serious violation of regulations.

When two operators used a test pen to test electricity, the test method was improper, resulting in short circuit and burning two people.

brief introduction

At noon on May 28th of a certain year, Gao Mou, the operation guardian of a factory, and Jia Mou, the operator, prepared to measure the insulation resistance of the 381V motor. Before the measurement, electricity was needed. When Gao Mou, the guardian, checked the electricity with a test pen in the power switch cabinet, the test pen did not light up (the equipment was indeed out of power). They suspected that there was something wrong with the test pen. In order to confirm the quality of the test pen, they went to another live switchgear for verification. The operator Jia stood on the side to illuminate with a flashlight, and the guardian Gao checked the electricity. When the test pen reached into the switch cabinet, the metal part of the test pen contacted the cabinet, which caused short-circuit discharge to the ground and the arc light burned them.

Causes and exposure problems

1. The guardian directly operates in serious violation of regulations;

2. Serious violation of regulations, expanding the scope of electricity inspection, and conducting electricity inspection in other switch cabinets without authorization;

3. The electricity test method is improper, and the metal part of the electricity test pen is in contact with the cabinet.

knowledge points

1. Electrical switching operation must be performed by two people, one of whom is familiar with the equipment as a guardian. The operator is responsible for the operation and the guardian is responsible for the guardianship;

2. The metal rod part of the test pen should have an insulating sleeve. Before checking the electricity, you should test the test pen before using it.

The system stipulates that

the following matters should be paid attention to when using the low-voltage test pen (electroprobe):

(1) Before the test, the charged body should be checked to confirm that the test pen is in good condition to prevent misjudgment;

(2) When using the test pen, it is best to wear insulating shoes;

(3) avoid observing neon bubble glow in bright light direction, so as to avoid misjudgment due to unclear sight;

(4) Some devices are often charged by induction. In addition, some metal skins also have induced electricity. In these cases, the test of electricity with a test pen cannot be used as the basis for the danger of electric shock. Other methods (such as measuring with a multimeter) must be used to confirm whether it is really charged. Case Analysis Summary How to Write 2

The social marketing of Didi's renaming is the most well-known among the public. At the beginning, the start-up interface of Didi taxi was changed to "Didi taxi, goodbye", and then six posters were released through the official Weibo, which caused various speculations from users, mainly focusing on whether Didi business turned around. Including rumors about stopping taxis, Didi renting cars to car owners to avoid restrictions, and the disappearance of express business, Didi taxi released the official Weibo rumor this afternoon. Objectively speaking, these rumors have played a considerable role in warming up Didi's name change.

Following Didi, the H5 Creative Page was launched the next day, and users scanned the QR code through WeChat to browse. Because the content was novel and widely circulated in the circle of friends, its content was mainly the idea of uninstalling and retaining the APP, which was a typical suspense promotion. At the same time, Didi has occupied the list of major application markets by doing ASO optimization, choosing the starting platform, and cooperating with developers to increase the download volume.

after data analysis, I found that Didi used the following mobile marketing tools in the marketing process of renaming: Weibo WeChat WeChat official account H5 QR code Android and Apple's application market. In this case, we can find that mobile marketing has a high degree of convenience:

1. Mobile terminals have inherent convenience

Practical and interesting mobile phone application services enable people to effectively use a lot of fragmentation time and attract more and more mobile phone users to participate; The opening of the platform also gives mobile phone users more personalized choices. People can keep abreast of the latest developments of Didi through mobile marketing tools such as Weibo WeChat public platform at any time, which is very convenient.

2. High accuracy

Didi Chuxing placed advertisements on Weibo and WeChat public platforms to attract a large number of young target users, locked the target groups matching their own projects in the vast sea of people, and effectively spread the new disc information. With the help of mobile public platform news, Weibo and other delivery systems, the information was four-dimensionally oriented (time-space orientation, terminal orientation, behavior orientation and attribute orientation) through accurate matching, and passed to the matching target groups.

3. The cost is relatively low

Due to the large scale of mobile terminal users, mobile marketing caters to the trend of the times and the needs of users with its characteristics and advantages of quickness, low cost and high coverage, and becomes a major opportunity and challenge in the new wealth era. Case analysis summary how to write 3

1. Product interface analysis

Because it is a tool-based app, the product setting must design its interface around its specific usage scenarios. Therefore, clicking on the app to enter the home page will show the number of taxis near the user, which shows how many taxis using Didi Chuxing Driver Edition are around me. Very intuitive display, users will directly feel how many taxis they will have and how long they will get a taxi if they send a taxi request.

this also exposes an opportunistic point in product design: it shows the number of taxis, not the number of empty cars, and uses a wrong expression to trigger a good user experience. Although most users will not consider this logic, it is debatable from the perspective of the rigor of product design.

second, the appreciation of the main color

Didi Chuxing uses orange as the main color, and all the most important modules, including logo, important operation area and WeChat payment waiver, use orange. Other interfaces are based on grayish white and dark gray. First of all, in terms of hue, orange is a warm color, which gives people a warm and intimate feeling.

Third, the operation process

Taxi calling operation: you can take a taxi after entering the destination, and a more concise operation will make users use it more smoothly;

booking operation: as the first step, use the booking button on the home page, select the booking time, the departure place and the destination place, and then you can make an appointment, which makes the booking service more concise;

payment operation: after the amount is entered, WeChat payment will pop up directly in Didi, and you can pay by entering the 6-digit password, which is faster and simpler.

Fourth, the passenger side:

1. Positioning navigation: With the help of LBS positioning function, the taxi APP software can send relevant information to the driver side through the positioning function, which is convenient for the taxi driver to find its position accurately;

2. online payment: calculate the travel expenses according to the specific route and time, and pay directly through online payment tools such as WeChat or Alipay after arriving at the place to complete the transaction;

3. taxi feedback: users can rate and give feedback on taxi service after the ride.

V. Driver's side:

1. Getting out of the car: log in to the taxi APP software and click the "Get Out of the Car" button to listen to/grab the ticket online;

2. Car collection: Click the "Car Collection" button after work, and then exit the software, so that no traffic consumption will occur;

3. Navigation is enabled: the navigation function on the driver's side is turned off by default. You can find "Navigation is enabled by default" in the settings, click the button on the right to turn it on, and the navigation route and voice prompts will be automatically displayed after successful ticket grabbing;

4. Night mode: The software is turned off by default, and the soft light interface after the night mode is turned on at night, which helps to relieve visual fatigue;

5. Offline map: After downloading the off-line map of your city completely, use map resources such as navigation to save traffic.
