Description
Technical Field
The invention relates to an electric heating technology, in particular to an electric heating regulation and control device based on a measurement and control separation technology and a regulation and control method thereof.
Background
The electric heating is a high-quality comfortable environment-friendly heating mode for converting clean electric energy into heat energy. In the field of electric heating, temperature measurement, load on-off switching and regulation control are usually performed by a thermostat integrated in a 86-box (junction box) housing. Namely, the temperature sensor and the high-power relay are limited to be in a shell with the square depth of 86cm and the depth of 25-45cm, and most of the shell is installed in a wall body.
Because the high-power relay is in the attraction state, the high-power relay can obviously generate heat after continuously working for several minutes. According to actual measurement, a plurality of high-power relays are arranged in the relatively closed cavity, the attraction state is kept for 10 minutes, and the temperature rise can be increased by about 35-40 ℃. And further causes the temperature in the whole temperature controller shell and the shell to rise, so that the temperature in the shell and the shell is seriously inconsistent with the ambient temperature outside the temperature controller to be detected, and the difference is huge.
Meanwhile, because the temperature sensor is welded on the PCB in the shell through a lead, the temperature sensor is led out and arranged by a plurality of temperature controllers, namely, the main part of the sensor is exposed outside the temperature controllers. However, since the wires also have a temperature conducting function and even if they are led out to the outside, they are exposed to a little outside the housing (usually within 1-2 cm), and the temperature inside the 86-box housing is radiated to the temperature sensor. The temperature controller has a serious influence on the measurement accuracy of the ambient temperature, and the measured value is far higher than the actual temperature of the environment to be measured (such as indoor), so that the ambient temperature cannot be truly reflected. The automatic control based on the ambient temperature does not achieve the desired goal.
And because 86 box size restrictions, the temperature rise of high-power relay can pile up gradually and continuously rise, this has seriously influenced the job stabilization nature of temperature controller, and binding post also produces because of the high temperature and the soldering between PCB board breaks away from, the rosin joint, and then produces the phenomenon of striking sparks. The hidden danger of electrical fire is buried, and the electricity safety is seriously influenced.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
Fig. 1 is a structural layout diagram of an electric heating control device based on a measurement and control separation technology, as shown in fig. 1, the structure of the invention includes an indoor control box corresponding to a user, a temperature sensing unit arranged indoors, and a switching unit for controlling the start and stop of a heating load laid indoors; a plurality of rooms are arranged indoors, the heating load and the temperature sensing unit are arranged in each room, and the temperature sensing unit is a temperature sensor; a switching unit is arranged corresponding to the heating load in each room in the room; the temperature sensing unit is connected with the input end of the indoor control box, the temperature sensors can communicate with the user-level controller in a wireless mode through 485 wires or 433M, 815M, 2.4G, WiFi and the like, which are not listed here, the output end of the indoor control box is connected with the switching unit, and the switching unit is connected with the heating load.
Fig. 2 is a schematic structural diagram of an embodiment of an electric heating control device based on a measurement and control separation technology according to the present invention, as shown in fig. 2, in the first embodiment, the switching unit is separately arranged from the indoor control box; the switching unit is an alternating current contactor arranged in each room of an indoor; and a household controller is arranged in the indoor control box, the household controller is connected with a power supply, and the power supply is also connected with a plurality of alternating current contactors in parallel. Preferably, the household controller is connected with a driving coil of the ac contactor through a driving cable, and a normally open contact of the ac contactor is connected between the heating load and the power supply. In the embodiment, the alternating current contactor is used as the load switching unit, and compared with a relay, the alternating current contactor is safer, is not easy to arc and ignite, has stronger loading capacity and is flexible in increasing and decreasing the number of paths; the disadvantage is the need to connect the drive wiring between the user-level controller and the ac contactor.
Fig. 3 is a schematic structural view of a second embodiment of the electric heating control device based on measurement and control separation technology, as shown in fig. 3, in the second embodiment, the switching unit and the indoor control box are integrally arranged; the switching unit is an alternating current relay arranged in the indoor control box, and a user-level controller is also arranged in the indoor control box; the household controller is connected with a driving coil of the alternating current relay, one end of a normally open contact of the alternating current relay is electrically connected with a live wire of a power supply, the other end of the normally open contact of the alternating current relay is electrically connected with one end of a heating load, and the other end of the heating load is electrically connected with a zero wire of the power supply. The embodiment integrates the high-power relay and the control part (a household controller) into an indoor control box, does not need to be connected with an external driving wire, has a small overall space, and has the defects of slightly lower safety than an alternating current contactor and relatively weaker load carrying capacity.
The regulation and control method of the electric heating regulation and control device based on the measurement and control separation technology comprises the following steps:
s1, setting a preset temperature value of a certain room, and storing the preset temperature value in the user-level controller after confirmation;
s2, the temperature sensor collects the actual temperature value in the room, if the actual temperature value is lower than the preset temperature value, the user-level controller controls the switching unit corresponding to the room to suck, the heating load in the room is electrified to heat until the actual temperature value collected by the temperature sensor reaches the preset temperature value, and the user-level controller controls the switching unit corresponding to the room to be disconnected and stops heating; otherwise, no action is taken.
For further explanation, FIG. 2 is used as an example for illustration: the user operates the temperature sensor in the room 1, the preset temperature of the room is set to be 20 ℃, and after the confirmation key is clicked, the data are transmitted to the user-level controller. The user-level controller stores the preset value, compares the preset value with the room temperature of the room 1 detected by the temperature sensor in the room 1, and outputs driving voltage on a pair of driving lines connected with the alternating current contactor corresponding to the room 1 if the room temperature is lower than 20 ℃ (assumed to be 16 ℃), so that the alternating current contactor executes pull-in action. The heating load in the room 1 is energized to start heating.
When the temperature of the room 1 rises to be higher than 20 ℃ (the temperature sensor transmits the temperature change to the user-level controller every time), the user-level controller stops outputting the driving voltage to the driving wire connected with the alternating current contactor. The ac contactor 1 is released due to no driving voltage, and the heating cable of the room 1 loses power supply, and stops heating.
The switching process is executed in the indoor electric box, the temperature sensor is not influenced by the separately arranged alternating current contactor in the whole process, and the temperature detection is always relatively accurate.
Therefore, the electric heating regulation and control device based on the measurement and control separation technology with the structure avoids the temperature measurement influence on the temperature sensing unit caused by temperature rise after the switching unit is switched on by separating the temperature sensing unit and the switching unit, thereby improving the temperature measurement accuracy and facilitating the subsequent temperature control work.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made to the invention without departing from the spirit and scope of the invention.
