Abstract

The digital temperature controller, features a display where a sequence of data and questions is displayed, required for installation and use. The messages are displayed in full text. The use of any symbols except letters, numbers and standard characters is excluded. All control parameters are modified only by two buttons. All questions and information required during installation and use are stored in the memory of the controller. Additional written instructions are not necessary. The controller can thus really be used by any literate person. Since it supports full duplex communication it provides the possibility of monitoring and controlling the state of the system from a distant or near-by control room. By using calorimeters, integrated into the controller, the compactness of the solution in heating substations can be increased.

Digital temperature controller

The subject of the invention is a digital temperature controller in central hot springs, district heating, and air conditioners. It is intended for use in all types of facilities from small single-family houses to residential blocks and public buildings.

This invention solves four technical problems

Problem 1.

The digital temperature controller should be so easy to use that any normal and literate man can successfully use it, that is, a non-foreman without a knowledge, which is very user-friendly.

Problem 2.

The digital temperature controller should be designed in such a way that it will not require extensive written documentation, instructions, etc. even at the time of installation or later.

Problem 3.

The digital temperature controller must allow for low cost, simple and reliable bidirectional communication for all control valves and pumps they control, as well as for all the physical quantities it measures and other parameters.

Problem 4.

The digital temperature controller should also allow measuring the power consumption so that it can assume the function of the calorimeter.

Known solutions to these problems are as follows.

Problem 1.

Modern digital controllers have many features, programs and schemes of operation. The user must know with which combination of key presses he will be able to achieve a certain change. For this, the user's guide should be examined. The problem is that the instructions with a plethora of data for most people are too complicated and too demanding. Often instructions are also lost or partially damaged. Most controllers have at least four to five keys, switches or buttons, and five to ten different symbols that appear on the screen or are printed on the chassis, describing the state of operation and system elements. Different signal lights are often used. Keys and symbols are not standardized and uniform. Every manufacturer works on his own. Symbols are often similar to those of other appliances. However, the same symbol does not necessarily mean the same thing. Confusion is big. The more the regulator offers, the less the likelihood that the result will be positive. Instead of saving energy, it's often the opposite.

Problem 2.

Procedures for installing new programs on computers are known. When a disk is inserted into the computer, an installation program is automatically started which asks the user all the necessary questions. But this is not the case with regulators. Each regulator has attached written instructions for installation and use. The installer, on the basis of a complicated and often ambiguous instruction, performs the installation and parameter setting. The problem is that the instruction can be lost. Especially after a prolonged period, after several years of operation, the probability of disappearance or partial destruction of instructions is increasing. The more complicated and clever the regulator is, the less the likelihood that it will still be manageable after a long time without a written instruction. Often it is easier to acquire another new regulator than to train the old one.

Problem 3.

Some existing regulators allow remote monitoring of the position of the opening of the control valves and the operation of the circulation pumps. However, additional and relatively expensive devices are therefore needed.

Problem 4.

To measure the energy consumed, calorimeters are used, which are installed as independent units in boiler rooms or heat substations.

Solutions to problems with this invention

Solving the Problem 1. 1.1 The Digital Temperature Controller automatically interacts with the user in its spoken language via the display. The user only answers questions. The questions are asked in a way that, at the latest, after a few answers, they lead to the result. 1.2. Four buttons are sufficient to handle the controller. Next to the two direction keys (forward, back), the plus and minus keys. With the latter, we change the value of the parameter on the screen and also serve as an affirmative and no answer to the question. 1.3 All graphic symbols are excluded. There are no graphic symbols on the screen, nor on the regulator housing. Only letters, numbers, and some standardized characters are used (+, -, ° C,%, directional arrows)

The advantage of this way of working with the regulator is that anyone who is literate can use it, with no instructions and no expertise. The disadvantage is that it takes some more time to read a certain information or change a certain setting. Use the arrow keys to find the appropriate question at the basic level. With an appropriate answer, we move to depth, to a more demanding level, where we can already change certain settings.

Since the settings are only rarely needed to change, the time loss of a couple of minutes seems to be acceptable. This is a price for a much more important feature, namely that the regulator is always and for everyone understandable and useful. The advantage is also that the pilot screen serves as a room thermometer, an outdoor thermometer, a clock, a calendar, etc. Other information may also be displayed on the screen, such as energy consumption, heating costs, etc. ... 3

Solving the problem 2.

At the first setting, the digital temperature controller reports to the specialist who connected it, which sensors are correctly connected and what temperature they detect. The controller allows the expert to move each actuator on the valve manually (using the + and - buttons) in the desired direction, thus checking the correctness of the connection. Also, the regulator allows for each pump or user to manually activate and deactivate by means of the + and - buttons to check the correct connection.

The controller terminal blocks are multicolour. Each customer has his own color of terminal clips, which further reduces the possibility of incorrect connection.

Troubleshooting 3.

The communication between the controller and the control unit is two-way. This means that the control unit shows us the status of all consumers and sensors connected to the controller and other parameters. With the help of a control unit, we can also change the states of consumers and other parameters. In order to avoid communication errors, a communication protocol is used with the verification of the data transmitted. The control unit can be in the same building or several miles away. In the latter case, a public telephone or other network is used as a communication medium. 3.1 The lifetime of the pumps is for several decades. The greatest risk of damage to the pump occurs when the pump in the system is stationary. After a longer period of rest, the pump "sticks" and automatically fails to run. Such "sticking" causes the stone to be loaded onto the walls of the stationary turbine pumps. To prevent this, the digital temperature controller does not allow for a longer standby time, but is switched on for a short period of time for a specific time period. This ensures greater reliability of the pump operation and, at the same time, correctness when communicating with the control unit. 3.2. The condition of the actuator valve is undoubtedly one of the most important information of the heating system. Various mechanical particles that come through the pipeline can prevent the quality of the control valve from functioning properly, causing more or less damage. Therefore, the control valve actuator also contains a sensor that measures the current position of the valve plate. In this way, we can accurately determine and control the position of the control valve and point out a possible error.

Solving the problem 4.

Calorimeters designed for measuring energy are indispensable especially for district heating. Without them, it is not possible to accurately determine the amount of energy consumed by a particular consumer. The calorimeter needs information about certain temperatures and flows in the system for its operation. The digital temperature controller also needs this information and because it also contains a permanent memory (EEPROM), the regulator can perform the function of the calorimeter. The combined function of the calorimeter and controller in the common housing would definitely contribute to the compactness of the implementation of heat substations. 4

Description of the construction solution

Figure 1

The digital temperature controller consists of two parts, the base (1) and the pilot (2). The base can have the following connections: the two-way communication terminal with the central (3) per wire, the two-way communication link with the radio station (4), the two-way communication port with the portable computer (5), the two-way communication with the pilot, for temperature sensors (6), connections for circulating pumps (7), connectors for motor actuators of control valves (8), connector for one-way communication with a calorimeter (9) and an electrical supply connection (10). The controller base incorporates the elements necessary for the regulation, communication and storage of data. The pilot has a room temperature sensor, a button (11) and a display (12) on which the text is displayed. When the pilot is installed in addition to the controller in the home station, the room sensor must be switched off.

The digital temperature controller is designed so that any symbol, except for numbers, letters and some standard characters, is excluded entirely and wherever. This rule applies to texts on the screen and to the inscriptions on the casing.

The installation of a digital temperature controller by an installer-expert takes place as follows. With the help of the image located between the connectors and completely unambiguously shows the way of connecting sensors and consumers, the installer performs the wiring of the controller. Connectors with their color are indicated and run by the installer, and additionally prevent the possibility of wiring errors. The regulator module is then pushed into the wired base and switched on the power supply. On the display, the controller will print out which sensors are connected and what temperature they detect. Also, the installer will be able to manually check the performance of all consumers, in order to make sure that the wiring is properly wired. Additionally, there are some other questions that are asked on the screen for installers. These are questions that concern installation and settings of complex parameters. The installer does not need additional written instructions to perform the installation. All instructions are stored in memory in several languages. The language of communication may change during the installation.

To simplify the use of the regulator for an ordinary user, the first level of questions on the screen is the one that the user most needs. In the second level, they are the ones they rarely need. In the third level, however, there are issues that an ordinary user does not have access to in order to endanger the quality of regulation. Dangerous issues are protected by a special code.

The controller contains a personal program that does not allow the pumps to stand still for a long time. This ensures maximum service life of the circulation pumps. The position of the control valve is measured using a sensor integrated into the valve drive. This ensures precise control of the position of the control valve. The function of the calorimeter integrated into the controller does not require additional system interventions. The solution is derived programmatically based on the calculation, the parameters of which are determined by the temperature and flow.
