In winter, central heating is adopted in the northern region to provide residents with the indoor temperature required for life. In recent years, with the increase in the number of urban residents and the increasing air pollution caused by heating emissions and other factors, the adoption of effective energy-saving and emission-reduction methods has become the top priority of the current heating work.

At present, the heating method in the society mostly adopts the extensive collective heating method, and the demand value of the room temperature in the household cannot be effectively collected and utilized. At the same time, residents cannot automatically close and open the heating pipes according to their own actual conditions, resulting in the consumption of a large amount of heat when there is no need for heating at home. At the same time, the heating company cannot adjust the heating capacity according to the actual temperature value of the residents' existing houses. How much, resulting in a great waste of resources.

The installation of the existing switch-type room temperature controller solves the problem of keeping the original indoor decoration of the heat user unchanged, realizes the arbitrary adjustment of the indoor temperature by the heat user, and solves the inaccurate temperature measurement caused by some users moving the controller at will. The existing switch-type room temperature controller uses the power supply line in the original power switch and adopts the single live wire power-taking technology to provide power supply for the room temperature controller, which solves the tediousness of replacing the battery when the battery is dead for hot users. However, although the switch-type room temperature controller adopts the single live wire power-taking technology, there is a problem that it cannot be replaced when the heat user lamp switch is a double-control type, that is, the existing switch-type room temperature controller can only replace the single-control switch. The above-mentioned problems exist in the existing switch-type room temperature controller, which makes the product lack of versatility when it is popularized and installed, and some users cannot use it.

The working principle and working process of the switch-type room temperature controller with double control function of the present invention are: the whole controller is fixed to the fixed port of the standard switch through the back cover 2, and the back cover 2 is provided with a mounting hole 12, and the back cover 2 is fixed After completion, connect the switch main board 9 with the temperature control main board 3, buckle the front cover 1 on the back cover 2, and fix the entire controller on the room wall. The display 4 is used to display room temperature information, and the temperature control button 6 is three buttons, which are used for controller working state switching, parameter setting and query. The light control buttons 5 are three touch buttons for controlling the lamps.

The user's comfortable temperature setting value is set through the temperature control button 6 , and the temperature sensor 10 collects the indoor temperature, converts the temperature signal into an electrical signal, and transmits it to the MCU chip 101 . The MCU chip 101 converts the temperature value of the electrical signal into digital information, and displays it to the user through the display 4; after that, the MCU chip 101 controls the antenna 8 through the wireless module 102, and the antenna 8 is connected to the corresponding on-off control in the tube well in the user unit building. Communication between the on-off controller and the controller to realize information transmission (one-to-one two-way wireless communication between the on-off controller and the controller), according to the relationship between the current room temperature and the set room temperature, so as to control the opening and closing of the valve of the on-off controller, so as to achieve the goal of adjusting the indoor temperature Purpose: At the same time, the wireless module 102 can also collect the opening and closing status information of the on-off controller valve, and display it on the display 4 through the MCU chip 101 .

The single fire mains power input port 701 connects the mains power line to the controller, and the single fire mains power output port 702 on the controller outputs the mains power. The mains output of the single-fire mains output port 702 is realized by engaging and disconnecting the working circuit 901 of the magnetic latching relay in the circuit.

When the controller is powered off, the control module 108 sets the working circuit 901 of the magnetic latching relay to the disconnected state, and the output port 702 of the single fire mains power cannot directly output a large current for lighting the lamp. At this time, the full-wave rectifier circuit 902 is in series Connect the single fire mains input port 701 and the single fire mains output port 702 in the mains circuit. The full-wave rectification circuit 902 converts the alternating current into direct current and supplies it to the off-state single live-wire power-taking conversion module 107 for power-taking operation, and the off-state single live-wire power-taking conversion module 107 stores the obtained power to the power storage module through the LDO step-down circuit 904 106 in. Because there is only a weak current in the line when the off-state single live wire power-taking conversion module 107 takes power, which is not enough to light up the attached lamps, so the entire off-state power-taking operation is completed.

When the controller is in the open state and does not take power, the control module 108 puts the magnetic latching relay working circuit 901 in the pull-in state. At this time, the full-wave rectification circuit 902 cannot obtain power, so the controller does not have power-taking operation. When the lamp is on, the voltage detection circuit 905 performs a voltage detection operation on the power storage module 106 at all times. When it is detected that the voltage on the power storage module 106 is lower than the protection value, the voltage detection circuit 905 feeds back a corresponding signal to the control module 108 . The control module 108 turns on the low-voltage series intervention circuit 903 after receiving the signal that the power is low and exceeds the protection value, and at the same time turns off the magnetic latching relay working circuit 901 . When the working circuit 901 of the magnetic latching relay is disconnected, the full-wave rectification circuit 902 and the low-voltage series intervention circuit 903 are connected to the mains circuit at the same time. Since the voltage drop of the low-voltage series intervention circuit 903 is relatively small compared with the 220V mains, the lamp does not work at this time. There will be a phenomenon of dimming or extinguishing. The low-voltage series intervention circuit 903 transmits the electric difference generated by itself to the open-state single-line power-taking conversion module 105 by connecting it in series with the mains circuit, and the open-state single-line power-taking conversion module 105 stores the obtained electric energy through the LDO step-down circuit 904 to the power storage module 106 to realize the power-taking operation in the open state. When the voltage on the power storage module 106 rises to the protection value, the voltage detection circuit 905 transmits a corresponding signal to the control module 108, and the control module 108 attracts the magnetic latching relay working circuit 901 after receiving the response signal and simultaneously intervenes the low voltage in series. The circuit 903 is closed, so that the output port of the single fire mains power returns to the mains output state.

The controller has two modes of weak current signal and strong current on-off, and the mode selection is performed through the dual control mode selection circuit 908 . The dual control mode selection circuit 908 can manually set the corresponding control mode, and transmit the set state information to the control module 108 . The control module 108 switches the corresponding control mode according to the received information.

When in the weak current signal mode, the other switch on site is the weak current mode switch 907, the strong current mode switch 906 does not exist, and the single fire mains output port 702 is directly connected to an external load 909 such as lamps. The control module can receive the status information of the light control button 6 from the temperature control main board 3 in real time, and can also detect in real time whether the switch operation of the weak current mode switch 907 occurs. Then the main control module 108 finally determines whether the working circuit 901 of the magnetic latching relay is on or off after logical judgment according to the two pieces of information, so as to realize the lamp control operation.

In the strong current on-off mode, the other switch of the system is the strong current mode switch 906, and the weak current mode switch 907 does not exist. The single fire mains output port 702 is connected to the strong current mode switch 906 , and the single fire mains output port 702 is disconnected from the external load 909 . During on-site installation, the strong current mode switch 906 can also be connected to the mains live wire first, then to the single-fire mains output port 702 of the controller, and then connected to the external load 909 via the single-fire mains input port 701 .

In the strong current on-off mode, the working circuit 901 of the magnetic latching relay is partly controlled by two magnetic latching relays. When the strong current mode switch 906 is inactive, the control module 108 passes the lamp control button sent by the temperature control board 3 6 information to perform corresponding operations on the magnetic latching relay working circuit 901. At the beginning, the control module 108 pulls in one magnetic latching relay in the magnetic latching relay working circuit 901 and disconnects the other. If the subsequently received lamp control status changes, the control module 108 will disconnect the magnetic latching relay that was originally engaged and at the same time pull in the previously disconnected magnetic latching relay, thus realizing the switching state of the lamp. When the strong current mode switch 906 performs the corresponding operation and the light control button 6 does not perform the switching action, the single fire mains output port 702 has two outputs, one of which is the magnetic latching state and the other is the disconnected state, and the two Status will not change. At this time, only the action state of the high-power mode switch 906 is used to switch the switch state of the lamp, thereby realizing dual-control operation.

What is not mentioned in the present invention is applicable to the prior art.
