Buildings constructed and used for purposes other than residential use, such as office buildings, commercial buildings, and educational buildings, are generally installed with system air conditioners that can provide air conditioning (cooling, heating, air purification, etc.) for the entire building.

In these system air conditioners, one large capacity (20 horsepower, etc.) outdoor unit controls multiple indoor units and supplies refrigerant.

Demand for system air conditioners is increasing due to various advantages such as convenience of maintenance and cost reduction.

Meanwhile, the number of sites requiring replacement or maintenance work for system air conditioners is increasing because the buildings are old or the system air conditioners have been installed for a long time.

However, in office buildings, commercial buildings, educational buildings, etc. where system air conditioning is installed, there is a limitation in that the entire building cannot be vacated for several days for construction, making it difficult to establish a construction plan and carry out construction.

Construction is mainly performed at night or on weekends, but if the construction plan is incorrectly established, the construction plan may not be completed, causing damage to office buildings, commercial buildings, and educational buildings.

According to one embodiment, a method of automating work scheduling and work distribution for building and installing an air conditioning system considering the work environment and human work status performed by the device includes the step of receiving work environment information (S100); Step of receiving personnel information (S200); Calculating a work schedule for building and installing an air conditioning system based on the work environment information (S300); Based on the calculated work schedule and manpower information, designating a first manpower to be assigned to the work schedule (S400); Sending a job participation proposal message to the first terminal of the first human resource (S500); Receiving a task participation acceptance message from the first terminal (S600); A first reassignment step (S700) of excluding a second workforce for which a work participation acceptance message has not been received from the first workforce and recruiting and updating the first workforce; A second reassignment step (S800) of sending a work participation proposal message to a second terminal of 'a third person among the first people who did not send a work participation proposal message'; and a third reassignment step (S900) of receiving a task participation acceptance message from the second terminal; A work environment comprising; a fourth reassignment step (S1000) of performing the first reassignment step (S700) to the third reassignment step (S900) until a participation acceptance message is received from all first personnel; It provides a method of automating work scheduling and work distribution for the construction and installation of an air conditioning system considering the work status of personnel.

The device may be any server computer. The device can receive input by transmitting and receiving data based on a client computer. The device can be connected to a certain database server to record/update data.

In the step of receiving the work environment information (S100), the address of the work site, the purpose of the work site (building) (office, commercial, educational, etc.), and the scale of the work (number of floors, area, outdoor unit capacity, number of indoor units, etc.) ) can be entered and stored in the database server.

In the step of receiving the human resources information (S200), a human resources pool is registered in the database server. Enter the worker's work competency/career/history information and contact information received/submitted from multiple workers. In particular, it is desirable that 'performable tasks' information, which will be described later, is input.

In the step of calculating the work schedule (S300), the starting time and ending time of the work, the start time and end time of the work for each day, the type of process for each day/time, etc. may be specified.

In the step (S400) of designating the first manpower to be assigned to the work schedule, manpower that can be assigned to the work schedule is designated, and at this time, manpower must be designated so that no part is omitted for each date/hour/process.

In the step (S500) of sending a work participation proposal message to the first terminal of the first manpower, based on the manpower information, it is proposed whether to participate in the work schedule with the first terminal corresponding to the first manpower. Send a predetermined message (SMS or application message).

In step S600 of receiving a task participation acceptance message from the first terminal, a response to the task participation proposal message is received from the first human resource. When the first person operates the task participation acceptance button on the first terminal, the task participation acceptance message may be received from the first terminal to the device.

A predetermined expiration period is specified in the task participation proposal message, and the first terminal and first person who do not respond within the expiration period are determined to have not accepted work participation (second person).

In the first reassignment step (S700) of excluding the second manpower from the first manpower and recruiting and updating the first manpower, among the first manpower, second manpower that has not sent a work participation acceptance message is selected. Except, the first workforce is reassigned by recruiting more than the number of excluded second workforce.

For example, if the second workforce is 5 people, those 5 people can be excluded from the 1st workforce and then another 6 people can be additionally designated as the 1st workforce.

In the second reassignment step (S800) of sending a work participation proposal message to the second terminal of 'a third person among the first people who did not send a work participation proposal message', in the second reassignment step (S800), although the person was designated as the first person, the existing work A work participation proposal message is sent to a third workforce that did not receive the participation proposal message (in the above example, six other people added to the first workforce).

In the third reassignment step (S900) of receiving a task participation acceptance message from the second terminal, a task participation acceptance message is received from a third person/second terminal in the same manner as the above-described step.

In the fourth reassignment step (S1000), the first reassignment step (S700) to the third reassignment step (S900) are performed until participation acceptance messages are received from all first personnel. By repeating the re-assignment process until a participation acceptance message is received for 1 personnel, all first personnel assigned to the work schedule confirm their intention to participate in the work.

Through this process, it is possible to explicitly check and manage whether the personnel assigned to the task are willing to participate in the task.

In addition, the step of calculating the work schedule (S300) includes: creating a first predetermined list of the air conditioning system construction and installation process; and, corresponding to the first list, generating first binary data having the same number of digits as the size of the first list.

In the step of creating the air conditioning system construction and installation process as a predetermined first list, the 'first list' is a 'list (variable type for storing data), one of the 'Collection' in programming language (variable type for storing data) List)'. The list may be replaced with any of other collections such as an array or linked list.

For example, 'removing refrigerant - cutting indoor unit wires - cutting indoor unit pipes - ceiling repair work - inserting a new indoor unit model - fixing a new indoor unit - installing a new indoor unit (piping welding) - replacing the outdoor unit - inspecting refrigerant leakage - vacuuming the refrigerant pipe - refrigerant Processes such as ‘injecting refrigerant into pipes’ {‘removing refrigerant’, ‘cutting indoor unit wires’, ‘cutting indoor unit pipes’, ‘ceiling repair work’, ‘inserting new indoor unit model’, ‘fixing new indoor unit’, ‘installing new indoor unit’ (Pipe welding)', 'Replacement of outdoor unit', 'Refrigerant leakage inspection', 'Vacuumizing refrigerant pipe', 'Injecting refrigerant into refrigerant pipe'} can be saved as data.

Corresponding to the first list, generating first binary data having the same number of digits as the size of the first list; in this step, the size of the 'first list', that is, the number of digits equal to the number of element values of the first list The branch creates (initializes) binary data.

For example, the above {'refrigerant removal', 'cutting indoor unit wires', 'cutting indoor unit pipes', 'ceiling repair work', 'insert new indoor unit model', 'fixing new indoor unit', 'installation of new indoor unit (pipe welding) ', 'Replacement of outdoor unit', 'Refrigerant leak test', 'Vacuum refrigerant pipe', 'Inject refrigerant into refrigerant pipe'} have a size of 11, so 00000000000, an 11-digit binary number, must be created and initialized as the first binary data. You can.

The generated first binary data can be used as a standard for determining the number of digits of second to seventh binary data, which will be described later.

The step of specifying the first manpower (S400) is: for each of the fourth manpower registered in the manpower information, tasks that can be performed from the first list are assigned to 1, and tasks that cannot be performed from the first list are assigned to 0. A first binary operation step (S410) of generating second binary data designated as; A second binary operation step (S420) of generating a second list in which the plurality of second binary data generated for each of the fourth personnel are sorted in descending order; A third binary operation step of extracting element values from index 0 to index 'n-1' of the second list as third binary data, based on the minimum number of workers 'n' described in the work environment information. (S430); A fourth binary operation step (S440) of generating fourth binary data by performing a 'logical sum' operation on the third binary data; A fifth binary operation step (S450) of determining whether all digits of the fourth binary data are 1; When all digit values of the fourth binary data are not 1, a sixth binary operation step of searching for fifth binary data, which is an element value whose digit value that was 0 in the fourth binary data among element values of the second list is 1. (S460); A seventh binary operation step (S470) of designating sixth binary data that has the lowest difference value from the fifth binary data among the third binary data; An eighth binary operation step (S480) of updating the third binary data by replacing the sixth binary data and the fifth binary data; And based on the third binary data updated in the eighth binary operation step (S480), the fourth binary operation step (S440) to the eighth binary operation step (S480) are repeated, but the fifth binary operation step (S480) It may include a ninth binary operation step (S490) in which repetition is stopped when all digit values of the fourth binary data are determined to be 1 in S450).

In the first binary operation step (S410), for each of the fourth personnel registered in the personnel information (all personnel recorded in the database server), the tasks that can be performed in the first list are set to 1, and the tasks that can be performed in the first list are set to 1. Second binary data is generated in which tasks that cannot be performed are designated as 0.

In other words, {'removing refrigerant', 'cutting indoor unit wires', 'cutting indoor unit pipes', 'ceiling repair work', 'inserting new indoor unit model', 'fixing new indoor unit', 'installing new indoor unit (pipe welding)', 'Replacing the outdoor unit', 'Inspecting for refrigerant leakage', 'Vacuumizing the refrigerant pipe', 'Injecting refrigerant into the refrigerant pipe'}, 'Removing refrigerant', 'Inspecting for refrigerant leakage', 'Vacuumizing the refrigerant pipe', 'Vacuumizing the refrigerant pipe' The second binary data for any person capable of an 'injection' operation can be generated as 10000000111.

A second binary operation step (S420) of generating a second list in which the plurality of second binary data generated for each of the fourth personnel are sorted in descending order; in the second binary data, each second binary data is sorted in descending order and then sorted in descending order. Save it to the collection to create a second list.

According to this process, the work capabilities of all fourth personnel can be converted into predetermined binary numbers and processed.

A third binary operation step of extracting element values from index 0 to index 'n-1' of the second list as third binary data, based on the minimum number of workers 'n' described in the work environment information. In (S430), based on the minimum number of workers (natural number) 'n' required according to the work environment information, only the same number of element values are extracted from the second list.

In the fourth binary operation step (S440) of generating fourth binary data by performing a 'logical sum' operation on the third binary data (an operation where the result is 1 when any of the two calculation target values is 1), extraction A logical sum operation is performed on all third binary data to generate fourth binary data.

At this time, since the logical sum operation is performed for each digit of the third binary data, if the value of any digit of the fourth binary data is 0, the value of the corresponding digit of all third binary data must be 0.

For example, if you perform a 'logical sum' operation on the four third binary data below,

11001010101

00111010101

11111111101

00000010100

As a result, the fourth binary data can be calculated as 11111111101.

In the fifth binary operation step (S450), which determines whether the values of all digits of the fourth binary data are 1, it is determined whether the values of each digit of the fourth binary data are all 1. In the above example, the second digit (2^1 digit) is 0, so it is determined to be 'negative'.

When all digit values of the fourth binary data are not 1, a sixth binary operation step of searching for fifth binary data, which is an element value whose digit value that was 0 in the fourth binary data among element values of the second list is 1. In (S460), if there is a capability (a task that cannot be performed) that the workers corresponding to the currently extracted third binary data do not have, other workers who can perform the task are searched from the second list.

In the seventh binary operation step (S470) of designating sixth binary data with the lowest difference value from the fifth binary data among the third binary data, the second binary data is the data most similar to the fifth binary data, which is the newly extracted element value. 6 Specify binary data.

Through this process, it is possible to prevent the capacity for other tasks (tasks that can be performed) from being eliminated due to replacement of personnel (replacement of the sixth binary data and the fifth binary data).

For example, if the 5th binary data is 00001010111 and the 6th binary data is 11111010101, the second digit (2^1 digit) changes to 1, but the 2^10 to 2^7 digits change to 0, so other digits If there is no attraction with 1 in 2^10 to 2^7 digits in the third binary data, the corresponding attraction must be searched again, so it is desirable to minimize this difference value.

In an eighth binary operation step (S480) of updating the third binary data by replacing the sixth binary data with the fifth binary data, the sixth binary data is removed from the third binary data, and the sixth binary data is replaced in its place. The personnel designation is replaced by adding new binary data to the fifth.

Based on the third binary data updated in the eighth binary operation step (S480), the fourth binary operation step (S440) to the eighth binary operation step (S480) are repeated, but the fifth binary operation step (S450) ) in the ninth binary operation step (S490), where repetition is stopped when all digit values of the fourth binary data are determined to be 1; by repeating the above-described process, capabilities for all tasks (tasks that can be performed) are determined. The list of participating personnel can be updated until it is ready.

And, the seventh binary operation step (S470) includes: calculating seventh binary data by calculating the fifth binary data and each digit value one by one for each of the third binary data (S471); For each of the seventh binary data, calculating first decimal data by summing each digit value in decimal notation (S472); and designating third binary data corresponding to second decimal data having the smallest value among the first decimal data as the sixth binary data (S473).

In other words, the process of 'designating the sixth binary data with the lowest difference value from the fifth binary data among the third binary data' can be replaced as described above.

When calculating the difference between two pieces of binary data according to a general binary calculation method, unintended weights may be reflected depending on each digit. For example, operations located at 2^10 digits will have very large weights.

Therefore, as described above, the difference value is calculated by separating the '1' or '0' value of each digit to prevent weighting by each digit, and the absolute values are added in decimal notation.

In other words, calculate the absolute value by calculating the difference between 2^10 digits, calculate the absolute value by calculating the difference between 2^9 digits, ..., calculate the absolute value by calculating the difference between 2^0 digits, and then calculate the absolute value. By concatenating the digits again, the seventh binary data can be calculated.

for example,

11010101010 (third binary data)

- 00010101010 (fifth binary data)

= 11000000000 (7th binary data)

-> 1 + 1 = 2 (first decimal data)

It is calculated as,

11010101010 (third binary data)

- 11010111111 (5th binary data)

= 00000010101 (7th binary data)

-> 1 + 1 + 1 = 3 (first decimal data)

It can be calculated as follows.

In addition, receiving whether a first partial task included in the work schedule is completed from a first terminal of the first human resource; And sending a notification of whether the second partial work has started to a third terminal of 'among the first human resources, a fifth person designated as the person in charge of the second partial work designated as a follow-up work of the first partial work'. More may be included.

In other words, after calculating the work schedule and designating/assigning manpower, and confirming participation in the work from each manpower, and confirming the work schedule, when each task is performed as above, it is checked whether or not each task has been completed. By receiving it, you can notify the operator of the subsequent task of the completed task to start the task.

The above notifications may operate based on application push notifications or certain message functions.

Since the refrigerant in the air conditioning system must be removed by a vacuum pump before cutting the indoor unit refrigerant pipe, the first part of the work includes: 'The work of removing the refrigerant of the air conditioning system by a vacuum pump', and the second part of the work includes: This may include 'cutting refrigerant pipes'.

'The operation of cutting the refrigerant pipe' may be designated as a follow-up operation to the 'operation of removing the refrigerant from the air conditioning system with a vacuum pump'.

The vacuum pump includes: a suction part connected to the air conditioning system; a main body connected to the suction unit; a discharge part connected to the main body and discharging fluid sucked by the main body; and a refrigerant removal unit connected to the discharge unit, wherein the refrigerant removal unit includes: a tower unit (1) having a predetermined internal space and formed in the shape of a hollow shaft rectangular pillar to have a predetermined height; A connection part (2) connecting the discharge part from the lower part of the tower part (1); A thermoelectric element unit (3) attached to the side of the tower unit (1) from the outside of the tower unit (1) to cool the surface of the tower unit (1); A plurality of wire meshes (4) arranged to be spaced apart at predetermined heights inside the tower portion (1); a plurality of spray nozzles (5) disposed at each lower part of the wire mesh (4) to spray water from the inside of the tower unit (1) toward the center of the tower unit (1); A hopper part (6) formed at the bottom of the tower part (1) to discharge water falling from the tower part (1); A first storage tank connected to the hopper unit (6) to store discharged water; A second storage tank connected to the spray nozzle (5) and supplying water; and a refrigerant amount measurement sensor disposed in the connection portion 2.

Common refrigerants used in modern times are made of ingredients that are harmless to the human body and do not pollute the environment. However, if the refrigerant is released into the air, there is a possibility of raising complaints from people nearby or causing other environmental problems that have not yet been discovered, so vacuum pumps It is necessary to separate and remove the refrigerant exhausted through it so that it does not disperse into the air.

Therefore, by connecting the refrigerant removal unit as described above to a general vacuum pump, the refrigerant component can be removed from the air exhausted from the vacuum pump.

An exhaust fan 7 is disposed at the top of the tower unit 1 to promote exhaust when the discharge pressure of the vacuum pump is insufficient.

A thermoelectric element unit 3 is attached to the side of the tower unit 1 to cool the surface of the tower unit 1.

The tower portion 1 is preferably made of a metal material with high thermal conductivity, such as aluminum.

Water particles contained in the air (sprayed by the spray nozzle 5) passing through the cooled tower unit 1 condense and grow, increasing the size of the particles, and refrigerant particles are attached to the condensed and grown water particles, thereby forming a predetermined amount. When the weight reaches the bottom, it falls to the bottom, or water particles with refrigerant particles attached collide with the wire mesh (4) and then fall to the bottom in the form of water droplets.

These water particles and refrigerant particles are discharged along the lower hopper and transferred to the first storage tank for storage.

A pump for spraying water and a pump for discharging water and refrigerant may be connected to the first storage tank and the second storage tank, respectively.

Additionally, the step of receiving whether the first partial task is completed includes: generating a first time limit notification at the expected end point of the first partial task in the first terminal; When completion processing for the first partial task is received from the first terminal before the first time limit notification ends, recording the first partial task as completed; Receiving a measured value from the refrigerant amount measurement sensor; If the first partial work is 'a work of removing refrigerant from the air conditioning system with a vacuum pump', recording that the first partial work is completed based on the measured value of the refrigerant amount measurement sensor; and when the first partial task is not recorded as completed until the first time limit notification from the first terminal ends, recording the first partial task as incomplete.

Generating a first time limit notification to the first terminal at the expected end point of the first partial task; generating a first time limit notification when the expected end point specified for each first partial task reaches the corresponding worker. Helps (the workforce) recognize that the planned task completion time has arrived.

When a completion processing for the first partial task is received from the first terminal before the end of the first time limit notification, recording the first partial task as completed; in each first partial task, When the worker directly inputs that the first part of the work has been completed before the designated expected end time, this is received and the work is completed.

In the step of receiving the measured value of the refrigerant amount measurement sensor, the refrigerant flow rate/concentration currently being removed is received from the refrigerant amount measurement sensor provided in the refrigerant removal unit.

If the first partial work is 'a work of removing refrigerant from the air conditioning system with a vacuum pump', recording that the first partial work is completed based on the measured value of the refrigerant amount measurement sensor is performed.

In other words, when the refrigerant quantity measurement sensor detects that the refrigerant is no longer discharged, the first part of the work can be automatically recorded as completed even without any separate operation by the operator.

In the step of recording the first partial work as incomplete when the first partial work is not recorded as completed until the first time limit notification from the first terminal ends; If the first terminal cannot be operated even though the first time limit notification is generated due to the work being done, the first partial task may be automatically processed as incomplete after a certain period of time has elapsed.

The step of sending a notification of whether the second partial task has started includes: when the first partial task is recorded as incomplete, sending a notification of a delay in starting the second partial task to the third terminal; And when the first partial task is recorded as completed, sending a notification to start the second partial task to the third terminal.

If the first partial task is recorded as incomplete, sending a start delay notification of the second partial task to the third terminal; in which, the priority task has not yet been completed to the worker who must perform the subsequent task. Therefore, a notification can be generated not to start the second part of the task.

For example, a notification can be issued to prevent cutting the indoor unit pipe while the refrigerant removal work is not completed.

When the first partial task is recorded as completed, sending a notification of the start of the second partial task to the third terminal; You can trigger a notification to start immediately.

For example, if the refrigerant removal work is completed earlier than previously planned, this can be immediately notified to a third terminal so that the follow-up work (second part work) can start immediately, thereby preventing gaps between tasks.
