The developed network capabilities of the S2000-T controller allow you to connect various slave devices, which the controller picks up automatically. Thus, from a connected two-wire communication line (DPLS) network, through a device manufactured by NVP "Bolid" S2000-KDL, which is a DPLS controller and connected to the S2000-T via the RS-485 interface, the master controller can receive data from the temperature and humidity sensors S2000- VT. Through one DPLS controller, up to 60 temperature and humidity sensors are available for monitoring. In addition, in addition to the S2000-T controller itself, you can connect up to 6 TE temperature sensors or various humidity converters. This allows you to build branched monitoring systems at objects such as archives, libraries, museums, etc. The user, using the Condition Block of the S2000-T controller, can easily program their own discrete outputs to turn on additional devices, for example: a dehumidifier, air conditioner or exhaust fan by threshold value from any sensor.

Functionality in operating mode:

• Monitoring of temperature and humidity values ​​measured by S2000 VT sensors and sensors connected to their own analog inputs
• Opportunity automatic switching on climatic equipment based on threshold temperature or humidity

Medicines require special conditions storage High humidity air (above 60%) in a pharmaceutical warehouse leads to spoilage of hygroscopic medications: potassium acetate, dry extracts, antibiotics, glucosides, enzymes and many others.

WST (Wireless Sensor Tags) is modern technology, which makes it possible to create effective system monitoring. The basis of such a system is touch tags autonomous type, providing comprehensive information about the situation at the site.

The temperature and humidity control system monitors the following parameters:

• temperature;
• relative humidity;
• movement;
• tilt angle;
• illumination

For the system to work, a tag manager is also used, which connects to the Internet and accesses each tag via a radio channel. Thanks to this, the manager can broadcast information from tags to a cloud database, which is accessible to any gadget connected to the Internet.

A basic climate monitoring system consists of:

• one WST-# tag;
• one WST-ETM manager.

The larger the territory under control, the more tags can be installed. Maximum quantity there are 40 of these devices connected to one manager.

Tag is small automatic device, which is located in a case-case. Inside there is:

• printed circuit board with electronic circuit;
• CR2032 lithium battery.

Today there are 5 types of tags:

• WST-13;
• WST-Pro;
• WST-Pro+;
• WST-Pro-ALS;
• WST-Pro-ALS+.

* - prices are indicated without taking into account the costs of the initial verification of WST-# tags as part of the WSTR-# complexes. The cost of verification is 2500 rubles. The inspection is carried out once every 2 years.

Description of tags based on differences in their characteristics

Characteristics of measurement channels

• The tags can record temperature fluctuations ranging from 40°C to +85°C.
• The measurement resolution is 13 bits (8192 points).
• The minimum temperature gradation that the tag records is 0.02°C.
• The measurement error varies depending on the temperature range, but does not exceed 1.2°C.
• The tag can measure humidity from 0% to 100%, with 10-digit resolution (1024 points) and 0.12% sensitivity. The error in measurements is no more than 5%.

Correct selection of tags is a guarantee of high-quality monitoring of temperature and humidity.

Main features of tags in the monitoring system

Tags are indispensable for a quality data collection process because:

The use of high-quality tags eliminates delays in the operation of the temperature monitoring system. The equipment promptly responds to changes in parameters and transmits the corresponding signal to connected devices.

The room temperature monitoring system is connected to power and the Internet. The WST-ETM manager is registered in the cloud database using the user login. All WST-# tags are attached to the manager via a radio channel. Next, the tags are placed at control points, which can be located at a distance of up to 200 m from the manager. The number of meters is reduced when there are any obstacles, such as walls.

To service more than 40 managers or devices located at a distance of 200 m, one or more additional managers are installed.

Thanks to the user-friendly interface, the user can always independently disable and enable tags and managers. The user also has access to settings responsible for:

• rate of registration of temperature, humidity, door position, movement, illumination;
• Battery charge status tracking and low battery notification;
• tag optimization;
• humidity monitoring.

In addition, the user can always view all the data displayed in graphical form using a convenient and intuitive interface. Thanks to it, you can visualize even individual fragments of reports and graphs, displaying hourly minimums/maximums.

The system makes it possible to download all the information that a tag has collected since it went live, unless materials have been specifically removed. All graphs can be easily printed or stored in a file with the most user-friendly extension.

You can also always download raw data from the cloud to document it.

In practice, we see that interested employees most often use their smartphones to monitor the microclimate:

Basic properties of simple monitoring tags

Most often, WST-13 tags are suitable for monitoring warehouses and refrigerators. The main advantage of the WST-Pro and WST-Pro-ALS models is the availability RAM, which allows you to buffer data in those moments when radio communication is lost for some reason and the information does not reach the cloud. After the signal appears, everything that has accumulated in the tag’s memory is automatically transferred to the database. This ensures high accuracy and objectivity of the results, regardless of possible failures in the Internet and power grid.

Also, the presence of built-in memory makes WST tags standalone loggers with high efficiency. Therefore, they are often used during the transportation of products that require maintaining a certain temperature.

For example, when goods are transported from a warehouse to consumers using insulated containers, which are returned to the warehouse, tags can be installed on them, and managers can be placed in the loading area. Once the manager detects the tag, he automatically reads all the information.

This system is also convenient in cases where products are stored in several warehouses and transported from one to another using thermal containers. In this case, all managers are grouped by including all WST-Pro tags that are installed in containers. When vehicle arrives at a specific point, the manager immediately reads the data and transfers it to the cloud.

We bring to your attention a software and hardware complex that implements centralized automated monitoring, registration and control of the microclimate at objects, regardless of their location. Information is received in real time.

Before installing permanent sensors, you should carry out temperature mapping of the object, which will allow you to identify critical points, as well as determine whether the room is suitable for the storage conditions of your products. This procedure allows you to detect storage areas with differences in humidity and temperature above the maximum permissible values.

The data obtained will allow you to accurately determine the location that is best suited for placing goods and the temperature sensors themselves for constant and timely monitoring of the microclimate. During the mapping procedure, we use a range of proven temperature recorders, it is carried out three times a year - summer, winter and autumn (or spring), in a room where all engineering work has been completed.

PTK equipment responds regulatory requirements installed for modern pharmaceutical industrial enterprises. At the same time, the complex fully satisfies the following provisions:

1. GMP/GDP/GSP standards for pharmaceutical industry facilities.
2. Standard for the control of production of medicinal products and food products (FDA 21CFR part 11).

Also, the PTK complies with the rules put forward by the Ministry of Industry and Trade regarding the organization production processes at pharmaceutical enterprises, as well as quality control of their products. The loggers used by the system are included in state registers SI Russian Federation and the Republic of Kazakhstan. This ensures the availability of this technology both on the domestic market and on trading platforms in neighboring countries.

Technical features of ShKPU modules

The universal parameter control cabinet included in the complex is designed for:

1. Connections for groups of temperature loggers, humidity sensors, pressure sensors, etc. in quantities from 1 to 15, 30 or 60 units as part of one control and diagnostic unit.
2. Visualization of data obtained during microclimate monitoring in the serviced area.
3. Providing light and sound signals when the controlled parameters deviate from the working limits.
4. Converting data and transferring it to the upper control level.

Inside the ShKPU, all the components necessary for the operation of the PTC are conveniently, compactly and neatly placed. To put the module into operation it is enough:

1. Securely secure it to the vertical plane of walls, columns or other planning details.
2. Connect power supply.
3. Perform routing from the ShKPU to the server that receives and processes control data.
4. Connect the number of sensors, loggers or other sensitive equipment necessary for effective monitoring of the microclimate in the serviced premises.

Several control cabinets can operate as part of one PTC - it all depends on the complexity and scale of the system for controlling and monitoring microclimatic parameters. In most cases, one ShKPU module is sufficient for one building, structure or functional complex of premises of the serviced enterprise.

The hardware design is developed in accordance with the hardware design hierarchy. In this case, the operational features of the control zone, as well as the prospects for modernization and functional expansion of the system serving a specific facility, must be taken into account.

The control cabinet package includes:

1. Actually, a monitoring and control cabinet.
2. 4 pieces of mounting anchor bolts.

Depending on the user’s needs, to organize the operation of the complex, components such as:

1. Temperature and relative humidity loggers DS1923-F5 series (designed for monitoring climate parameters in control zones with temperature conditions-20…+85 o C, have basic protection from moisture, dust and other aggressive operating factors)
2. Loggers DS1922L-F5 (have a frost-resistant, moisture-proof design and are designed to work in rooms with a temperature range of -40...+85 o C).
3. Cable adapter format 1w-2/3, incl. with a built-in temperature sensor, necessary for connecting loggers and sensors to the head equipment of the ShKPU.
4. A light and sound alarm system designed for timely notification of persons responsible for the operation of the complex and facility personnel about violations of the regulatory microclimate regime in control zones.
5. Service kit iBDLR-0-U for reprogramming loggers and reading operating data from them.

Characteristics of ShKPU and loggers

To organize the operation of the complex systems, the manufacturer has provided 3 types of ShKPU with dust and moisture protection IP41. They differ in the maximum permissible number of connected loggers or sensors.

The smallest control cabinets - ShKPU-1 - allow you to organize maintenance of premises with a total area of ​​no more than 1000 square meters. Only one logger loop can be connected to such a module, designed to install 15 control and measuring points, but during a power outage it can operate in autonomous mode for at least 4 hours.

Useful information: The standard cable length is 100 m and it is not recommended to exceed it, because this entails an increase in the error of control measurements to an unacceptable level.

ShKPU-2 are controlled by a group of 30 loggers or sensors placed on 2 loops. Cabinets of this category are included in the hardware and software systems for servicing facilities with an area of ​​up to 2000 sq. m.

The most spacious are ShKPU-4. They allow you to expand the complex to 60 sensors, and the latter are connected using 4 loops. This provides an increase total area control zone up to 4000 sq.m. The battery life of cabinets of categories 2 and 3 is within 2 and 1 hour, respectively.

The results of current measurements of loggers operating as part of the complex are displayed on the ShKPU display. Operating information is entered into the internal memory of the system and exported to the nearest server via Ethernet using TCP/IP data transfer technology. PTK optionally supports a number of alternative data interfaces. If necessary, the complex can establish communication with servers and clients of the complex through:

1. Radio broadcasts in the 433 MHz band.
2. Available GSM solutions.
3. RS485 standard (data transmission is carried out via Ethernet, but by sending/receiving differential electrical pulses).
4. Fiber optic lines.

Registration of temperature and humidity levels in controlled premises is carried out autonomously. First of all, the measurement results are entered into the logger memory, designed for 8192 records, and then sent to the server. Here they are entered into a journal and sent for further processing.

Useful information: ShKPU have restrictions on connecting pressure sensors: the latter are optionally included in the control and measuring system in an amount of no more than 4 units.

It remains to add that despite the difference in functionality, control cabinets of all three categories have the same dimensions (800*800*200) and weight 45 kg. The manufacturer recommends operating the ShKPU within the temperature range of +5...+40 o C and at indoor air humidity of no more than 93%. The discreteness of thermal measurements performed by the system loggers does not exceed 0.0625 o C, while the overall error in measuring temperature and humidity lies within +/-0.5 o C.
