Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Referring to fig. 1-3, a large space heating controller is composed of a main control board, a master control unit, an LCD display unit and a power supply module; the main control board is respectively and electrically connected with the main control unit, the LCD display unit and the power supply module;
the main control board comprises two control output interfaces, namely a variable frequency fan and a power thyristor control interface, and the two control ends can use three different output modes; the main control board is also provided with two fault detection input interfaces, two NTC temperature monitoring input interfaces and two control relay output interfaces;
the two fault detection input interfaces are connected with an optical coupler device, and can be connected with a switch type device or a relay device or can be directly driven by voltage;
the two NTC temperature monitoring input interfaces are respectively connected with an inlet air temperature sensor and an outlet air temperature sensor;
the two control relay output interfaces are respectively connected with a control fan relay and a control silicon controlled relay.
The number of the LCD display units is two, one is a main control panel with a 5-inch LCD display, and the other is a 10.1-inch LCD display equipped with the main control unit;
the master control unit can monitor and control 12 slave devices at most simultaneously in a wireless mode.
Still include wireless control module, wireless control module installs on the main control board, and with main control board electric connection, 433MHz antenna is connected to its other end.
Still include the WIFI module, the WIFI module is installed on the main control board, and with main control board electric connection, 2.4G antenna is connected to its other end.
Still include the 4G module, the 4G module is installed on the main control board, and with main control board electric connection, its other end connection 4G antenna.
When different matching modules are selected, the controller can have a plurality of terminal control modes: local control, wireless control and remote control.
The power supply module further comprises a 380V wide voltage power supply module, and the 380V wide voltage power supply module is electrically connected with the main control board.
The 380V wide voltage power module and the standard power board output +12V and GND polarities are opposite, and when the 380V power is used, the power lines are required to be in cross butt joint.
Specifically, the controller has three output control modes: 4-20mA output control, voltage output control and RS485 communication control. The variable frequency fan and the power controllable silicon can be controlled by any output. The three control wiring methods are different, and each control method also has a different wiring mode.
As shown in fig. 4, the 4-20mA current loop connection for the power supply from the main control board is the most basic connection. The highest output voltage of the wiring mode can only reach 12V, and if the loop resistance RT of the frequency converter or the silicon controlled rectifier is too large, the maximum current cannot be output. When RT is less than 600 ohms, the loop may go to a maximum of 20mA current according to U = I × R. More than 600 ohms will not output 20mA current;
however, the power output of the frequency converter can be used as the loop power supply, and fig. 5 shows the principle and wiring method of the power supply of the frequency converter.
As shown in fig. 4, the voltage control method is used. In order to be compatible with two output voltages of 0-5V and 0-10V, a jumper wire is arranged on the main control board to flexibly switch the output voltages. However, please note that, first, what voltage of your frequency converter or thyristor should be determined and then set, otherwise, setting 0-10V output on 5V equipment may damage the frequency converter or thyristor;
the fan frequency converter control voltage setting is set by a W1 jumper wire of the PCB, the voltage is set to be 0-5V output when the W1 is short-circuited, and the voltage is set to be 0-10V output when the W1 is disconnected. The output voltage setting of the controllable silicon is set by a W2 jumper, and the set output is the same as W1; FIG. 7 shows the positions of W1 and W2 in the PCB.
As shown in FIG. 8, the RS-485 output control mode is adopted. The main control board is provided with an RS-485 transceiver, the frequency converter and the controlled silicon can be controlled simultaneously, and the wiring mode is very simple.
The utility model discloses the theory of operation: the utility model provides a large space heating controller, which is used for controlling a control device for heating a large power space, and controlling power silicon controlled rectifiers and variable frequency fans in real time in a temperature monitoring mode to realize temperature control on an environment space; meanwhile, the product is displayed by an LCD, and a simple control interface can feed back the running state in real time.
