A plurality of touch switch units are arranged in the same hotel room electrical equipment control system, and 2 or more than 2 electrical switch devices in any touch switch unit can be configured into an interlocking state to act in a unified manner. The plurality of appliance switching devices configured to be interlocked can be arbitrarily selected and combined among a plurality of touch switch units in the distributed wireless communication network, and can be from the same or different touch switch units, or both the appliance switching devices in the same touch switch unit and the appliance switching devices in different touch switch units. Any number of touch switch units means 1 or more than 1 touch switch unit.

When part of the electrical appliance switch devices in the touch switch unit of the electrical appliance equipment control system of the hotel guest room are already configured to be in an interlocking state, the electrical appliance switch devices configured to be in the interlocking state are regarded as 1 switch group; the rest electric appliance switch devices can still be selected and combined to be configured into an interlocking state to form another 1 switch group; in the same hotel room electrical equipment control system, the switch group configured to be in the interlocking state may be 0 group, may be 1 group, or may be multiple groups.

There are various ways in which the switch may be configured to interlock. For example, all switches are set to have their functions, and by setting the switch functions, the switches having the same function or the same controlled object are set to be in an interlocked state, that is, all switches in the same hotel room electrical equipment control system that are consistent with the controlled object are in the interlocked state. Or all the switches are coded (or numbered), and all the switches with the same codes in the same hotel room electrical equipment control system are in an interlocking state; and so on. When only one switch of a controlled object is correspondingly set, namely the function of a certain switch is unique, or the code of a certain switch in the same hotel room electrical equipment control system is unique, the switch is not interlocked with other switches in the same hotel room electrical equipment control system.

When the plurality of electrical appliance switching devices are configured to be in the interlocking state, the power supply of the controlled object can be controlled by the output of the switch driving module of any one or more electrical appliance switching devices. For example, 2 electrical appliance switch devices using relay outputs are configured to be interlocked to control the exhaust fan, after any one switch input module of the 2 electrical appliance switch devices is operated, the 2 relays will act simultaneously, i.e. output power simultaneously or cut off power simultaneously, and the power of the exhaust fan can be connected to the output end of any one of the 2 relays. If 1 switch is to be implemented to control multiple controlled objects, the multiple controlled objects may be controlled by connecting to the outputs of different switches in the switch configured in the interlocked state.

For example, in3 touch switch units in the distributed wireless communication network shown in fig. 1, there are 4 electrical switch devices, or 4 switches, respectively K11, K12, K13, and K14 in the touch switch unit 300; there are 5 electrical switching devices, or 5 switches, respectively K21, K22, K23, K24, and K25 in the touch switch unit 400; the touch switch unit 500 has 3 electrical switch devices, or 3 switches, K31, K32, and K33, respectively. Example 1, the electrical switch devices from 3 touch switch units are respectively configured to be in an interlocking state, for example, K11, K23 and K32 are configured to be in an interlocking state to control room lamps, and the power of the room lamps can be connected from the output end of any one of K11, K23 and K32; the control of the room lamp can be realized by operating any one of the switches K11, K23 and K32. Example 2, K21, K22, K33 are configured to be interlocked to control the exhaust fan, and since K21, K22 are in the same touch switch unit, the outputs of K21, K22 can be connected in parallel to control the exhaust fan, which can improve the load carrying capacity, of course, the exhaust fan can also be controlled by the output of K33; the control of the exhaust fan can be realized by operating any one of the switches K21, K22 and K33. Example 3, if it is only necessary to improve the loaded capacity, only a plurality of electrical switch devices in one touch switch unit may be configured to be in an interlocking state, for example, K23, K24, and K25 may be configured to be in an interlocking state, and then outputs of K23, K24, and K25 may be connected in parallel to control the electric heater, and any one of the switches K23, K24, and K25 may be operated to control the electric heater; compared with the common switch which is connected in parallel and then controls the electric appliance, the parallel interlocking control of the touch switch unit is automatically synchronous after interlocking, and the parallel interlocking control respectively operate and simultaneously act; the common switches need to be operated simultaneously, if only one switch in the parallel connection of the common switches is switched on, the load is still controlled by the switch, only when all the parallel switches are switched on simultaneously, all the parallel switches supply power simultaneously, and only when all the parallel switches are switched off, the load is switched off.

The function (or control object) of the write switch or the number of the write switch in the switch is called a configuration, and there are various methods of configuring the switch or configuring the switch group in an interlocked state.

The configuration is performed at the time of production. During production, the configuration information of the switch is set to be consistent with the screen printing name on the panel, for example, if the screen printing name on the panel is night light, the corresponding switch function is configured to be a night light switch; the screen printing name on the panel is a wall lamp, and the function of the corresponding switch is configured as a wall lamp switch; the screen printing name on the panel is the ventilator, and the corresponding switch function is configured to be a ventilator switch; when the switch is in the same distributed wireless communication network with the touch switch unit where other switches are located through the touch switch unit, and the switch is configured to have the same switch function, the switch automatically becomes an interlocking state. For example, when the functions of 3 switches in the same distributed wireless communication network are configured as wall lamp switches, the 3 wall lamp switches automatically become an interlocking state; when only one switch is configured as the ventilator switch, the ventilator switch controls the ventilator alone. The spare switch, or when the switch is not configured in function during production, may be set to a special switch named as an unconfigured function, for example, set to the spare switch uniformly, or set to the unconfigured switch uniformly, or set to other names; all switches with the functions of a standby switch (or a non-configured switch) do not form a switch group and are not in an interlocking state. In actual configuration, the switch function may be replaced by a number, for example, a No. 1 switch controls a wall lamp, and when the function of 2 switches in the same distributed wireless communication network is configured as the No. 1 switch, the 2 switches No. 1 automatically become an interlocked state. The spare switch, or when the switch is not configured in function during production, may set a special number, for example, set to 0, that is, the switch 0 is a switch that is not configured in function, and therefore, in the same distributed wireless communication network, even if there are a plurality of switches 0, the switch group will not be formed, that is, the switches 0 are not configured in an interlocked state; the special number is not necessarily 0, and other numbers, such as 999, 511, etc., may be selected.

The configuration is performed or modified in the field. A computer or a special configuration tool is accessed to a control system of the electrical equipment of the hotel guest room on site to carry out networking unified configuration; or the single touch switch unit is connected with a computer or a special configuration tool to carry out independent configuration.

Firstly, a computer or a special configuration tool is connected to a field hotel room electrical equipment control system or is connected with a single touch switch unit;

editing functions or numbers of switches needing to be configured in a relevant engineering configuration interface of a computer or a special configuration tool and selecting the switches, or selecting the switches with the edited functions or numbers;

the selection switch is configured to complete configuration confirmation; if the switch group needs to be configured, continuing to select the switches for configuration until all the switches of the switch group and the selected switches in the engineering configuration interface are completely configured and confirmed;

and fourthly, returning to the step II (configuration in an on-site hotel room electrical equipment control system) or the step II (configuration of a single touch switch unit) to configure other switches.

And step three, configuring the selection switch, and performing a plurality of methods for confirming the configuration, wherein one of the methods is to perform one-time switch operation to realize new configuration and cancel old configuration. For example, a room lamp switch is prepared and configured, a switch corresponding to a room lamp is selected in a relevant engineering configuration interface, and then a certain switch needing to be configured is operated once, so that the switch is configured to have the same switch function or the same switch number as the selected switch in the engineering configuration interface, and other switch functions or switch numbers which are configured once are cancelled; the other switch is operated once again, the other switch is also configured to have the same switch function or the same switch number as the switch selected in the engineering configuration interface, and the front switch and the rear switch are also configured to be 1 switch group; and then, the other switches are operated, so that the number of the switches of the switch group is increased. The second method is that all switches have the status indication of whether the switch is configured; if the switch which is not configured is subjected to the state indication display, the switch is subjected to one-time switch operation, new configuration is carried out, and the state indication display configuration is successful; when the switch with the status indication display configuration success is subjected to one-time switch operation, the configuration is cancelled, and the status indication display is not configured; the unconfigured switch can be set as a standby switch, or set as an unconfigured switch, or set as other names; the unconfigured switches may also be set to switch No. 0, or to other special numbers. Whether the configured state indication is available can be distinguished by the on and off of the indicator light, can be distinguished by the flicker of the indicator light, can be distinguished by the different flicker frequencies of the indicator light, and the like.

The interlocked configuration of all touch switch units can be reconfigured, reconfigured and the like changed at any time.

When the touch switch unit does not form a network with other distribution units, the touch switch unit can be set to be in an independent working mode and independently works.

For example, when a card is required to be inserted to transmit power, other distribution units in the hotel room electrical equipment control system can only operate in an effective card insertion state; when the distributed wireless communication network breaks down, other distributed units cannot acquire the card inserting state of the power switch unit, and if no card is inserted, the other distributed units can not acquire the card inserting state of the power switch unit. The other distribution units can also be set to operate only in an effective card insertion state when the electrical equipment control system of the hotel guest room works normally; when the distributed wireless communication network fails or is not networked with other distributed units, the distributed units can work independently, for example, the touch switch unit can be operated independently and controlled independently.

The hotel guest room electrical equipment control system may further include 1 or more electronic doorplate units in the plurality of distribution units, and fig. 6 is a structural diagram of an embodiment of the electronic doorplate unit, and includes a microcontroller module, i.e., a doorplate microcontroller module 601, a communication module 602, and a doorplate display module 603. The communication module 602, the doorplate display module 603 and the doorplate microcontroller module 601 are electrically connected or have a photoelectric isolation relationship for transmitting related signals.

The electronic doorplate unit synchronously displays relevant information in the electrical equipment control system of the hotel guest room, including information of not disturbing, requesting service, requesting cleaning, requesting later and the like. The communication module 602 joins the distributed wireless communication network in the same manner as the communication modules in the 4 distribution units shown in fig. 1; the electronic doorplate unit realizes communication with other distributed units through a distributed wireless communication network via a communication module 602; the communication module 602 is used for transmitting data to other distribution units and receiving data from other distribution units.

The electronic doorplate unit may further include a doorbell button 604, the doorbell button 604 being in electrical connection with the doorplate microcontroller module 601 or in electrical connection with opto-electrical isolation. When the electronic doorplate unit comprises the doorbell button 604, a doorbell unit needs to be added indoors. The doorbell unit comprises a doorplate microcontroller module, a doorbell unit communication module and a doorbell module. The doorbell unit communication module, the doorbell module and the doorplate microcontroller module are electrically connected or have photoelectric isolation for transmission of related signals. The doorbell unit is used for receiving doorbell button information of the electronic doorplate unit and other related information in the hotel guest room electrical equipment control system, such as information of a current contextual model and the like, and controlling the alarm state of the doorbell together. The function of the doorbell unit can also be combined with the functions of other distributed units to form a combined unit. For example, if a doorbell module is added to the room access point unit, the room access point unit has the functions of both the power-taking switch unit and the doorbell unit.

The hotel room electrical equipment control system can also comprise 1 or more curtain control units in a plurality of distribution units. Fig. 7 is a block diagram of an embodiment of a window covering control unit, which includes a microcontroller module, i.e., a window covering microcontroller module 801, and a communication module 802, a window covering 1 setting module 803, a window covering 2 setting module 804, a window covering 1 opening/closing driving module 805, and a window covering 2 opening/closing driving module 806. The communication module 802, the curtain 1 setting module 803, the curtain 2 setting module 804, the curtain 1 opening/closing driving module 805, the curtain 2 opening/closing driving module 806 and the curtain microcontroller module 801 are electrically connected or electrically connected with photoelectric isolation for transmitting relevant signals. The curtain control unit shown in fig. 7 includes 2 curtain controllers, that is, a curtain controller 1 and a curtain controller 2; one curtain control unit may include only 1 curtain controller, or 3 or more curtain controllers.

The communication module 802 joins the distributed wireless communication network in the same manner as the communication modules in the 4 distributed units shown in fig. 1; the curtain control unit communicates with other distribution units through the distributed wireless communication network via the communication module 802, and functions to transmit data to other distribution units and receive data from other distribution units.

The curtain microcontroller module 801 functions to include: analyzing the data received by the communication module 802 to achieve synchronous control with the curtain controllers in other curtain control units; the control operation and the state of the curtain control unit form data and are sent out through a communication module 802; judging and identifying the states and operations of the curtain 1 giving module 803 and the curtain 2 giving module 804; controls the states of the curtain 1 open/close driving module 805 and the curtain 2 open/close driving module 806.

The curtain 1 given module 803 and the curtain 2 given module 804 both include a curtain open switch, a curtain close switch, and a curtain stop switch or button, and the curtain open switch, the curtain close switch, the curtain stop switch or button is a touch switch or a touch button.

The curtain opening/closing drive modules, for example, the curtain 1 opening/closing drive module 805 and the curtain 2 opening/closing drive module 806, each include a curtain opening drive device and a curtain closing drive device, and the curtain opening drive device and the curtain closing drive device may be composed of an electromagnetic relay, a solid-state relay, a thyristor, and their drive circuits. The curtain opening driving device and the curtain closing driving device can respectively drive the curtain opening motor and the curtain closing motor to operate, or respectively drive the curtain motor to operate in forward and reverse directions, so as to realize the opening and closing of the curtain. If the curtain motor has the remote control function, the curtain opening/closing driving module generates and drives the transmitting circuit for the corresponding remote control signal. The curtain motor adopts a motor with a function of automatic stop when meeting a resistance.

In the same hotel room electrical equipment control system, 2 or more than 2 curtain controllers in any curtain control unit can be configured into an interlocking state to act in a unified way. The plurality of shade controllers configured in the interlocked state can be arbitrarily selected to be combined among a plurality of shade control units in a distributed wireless communication network. The shade controllers configured in an interlocked state operate on any one of the shade controllers, all of the shade controllers are simultaneously actuated. For example, there are A, B two curtain control units in the same hotel room electrical equipment control system, there are curtain controller 1 and curtain controller 2 in unit a, and there are curtain controller 3, curtain controller 4 and curtain controller 5 in unit B. Now, the curtain controller 1 and the curtain controller 5 are configured to be in an interlocking state, and when the curtain controller 1 performs curtain opening operation, the curtain controller 1 and the curtain controller 5 both perform curtain opening driving action; when the curtain controller 5 performs a curtain closing operation, both the curtain controller 1 and the curtain controller 5 perform a curtain closing drive operation. In practical application, the driving motor of the curtain can select one curtain controller to actually control, and other curtain controllers are used for realizing other control. The interlocking configuration of the window shade controllers in all the window shade control units can be cancelled at any time or changed operation such as reconfiguration can be carried out.

When some curtain controllers in the curtain control units of the electrical equipment control system of the hotel room are configured to be interlocked, the curtain controllers configured to be interlocked are regarded as 1 curtain control group; the remaining shade controllers can still be selectively combined and configured into an interlocked state to form additional shade control groups; in the same hotel room electrical equipment control system, the curtain control groups configured in the interlocking state can be 0 group, 1 group or a plurality of groups.

The shade controller is configured to interlock in the same manner as the electrical switch device is configured to interlock in a variety of ways and methods. For example, the interlocking is performed by setting a controlled object, that is, all the curtain controllers are provided with one controlled object, and all the curtain controllers in the hotel room electrical equipment control system, which are consistent with each other, are in an interlocking state; in the example of the aforementioned A, B two curtain control units, when the curtain controller 1 and the curtain controller 5 are both configured to control the main curtain and the curtain controller 2, the curtain controller 3, and the curtain controller 4 are configured to control the other curtains, the curtain controllers 1 and 5 are configured to be interlocked. Or all the curtain controllers are coded, and all the curtain controllers with the same codes in the hotel guest room electrical equipment control system are in an interlocking state; and so on.

The number written in the control object of the curtain controller or written in the curtain controller of the curtain control unit is called the configuration. There are various methods of configuring the shade controllers, or the shade control groups, as the switches.

The configuration is performed at the time of production. During production, the configuration information of the curtain controller is set to be consistent with the silk-screen name on the panel, for example, if the silk-screen name on the panel is the main curtain, the corresponding curtain controller function is configured as the main curtain controller; if the screen printing name on the panel is an auxiliary curtain, the function of the corresponding curtain controller is configured into an auxiliary curtain controller; the screen printing name on the panel is a small curtain, and the corresponding curtain controller function is configured to be a small curtain controller; when the curtain controller is in the same distributed wireless communication network with the curtain control units in which other curtain controllers are located through the curtain control unit in which the curtain controller is located and is configured as the controller function of the same curtain, the curtain controller automatically becomes an interlocking state. For example, when there are 3 curtain controllers configured as the sub-curtain controller in the same distributed wireless communication network, the 3 sub-curtain controllers automatically become the interlocked state; when only one curtain controller is functionally configured as a small curtain controller, the small curtain controller controls the small curtain alone. The standby curtain controller, or when the curtain controller is not configured in function during production, may set a special curtain controller named as the unconfigured function, for example, set the standby curtain controller uniformly, or set the unconfigured curtain controller uniformly, or set the curtain controller as another name; all curtain controllers with the functions of standby curtain controllers (or curtain controllers without other names such as curtain controllers) do not form a curtain control group and are not in an interlocking state. In actual configuration, the curtain controller functions may be replaced by numbers, for example, when the curtain controller 1 controls the sub-curtain, and when the functions of 2 curtain controllers are configured as the curtain controller 1 in the same distributed wireless communication network, the 2 curtain controllers 1 automatically become the interlocked state. The standby curtain controller, or when the curtain controller is not configured in function during production, may set a special number, for example, set to number 0, that is, the curtain controller No. 0 is a curtain controller that is not configured in function for the curtain controller, and therefore, even if there are multiple curtain controllers No. 0 in the same distributed wireless communication network, they will not be combined into a curtain control group, that is, multiple curtain controllers No. 0 are not configured in an interlocked state. The special number is not necessarily 0, and other numbers, such as 999, 511, etc., may be selected.

The configuration is performed or modified in the field. Accessing a computer or a special configuration tool in a field distributed wireless communication network to perform networking unified configuration; or the single curtain control unit is connected with a computer or a special configuration tool to carry out independent configuration.

Firstly, a computer or a special configuration tool is accessed to a field distributed wireless communication network or is connected with a single curtain control unit;

editing the function or number of the curtain controller to be configured in a relevant engineering configuration interface of a computer or a special configuration tool and selecting the function or number, or selecting the curtain controller with the edited function or number;

selecting a curtain controller in the curtain control unit to configure to complete configuration confirmation; if the curtain control group needs to be configured, continuously selecting the curtain controllers for configuration until all the curtain controllers of the curtain control group and the selected curtain controllers in the engineering configuration interface are completely configured and confirmed;

and fourthly, returning to the step II (configuration in the on-site distributed wireless communication network) or performing the step I (configuration of a single curtain control unit) to perform configuration of other curtain controllers.

And one of the methods is to perform one curtain controller operation to realize new configuration and cancel old configuration. For example, when a main curtain controller is prepared to be configured, the main curtain controller is selected in the relevant engineering configuration interface, and then a certain curtain controller is operated once (opened or closed), the curtain controller is configured to have the same curtain controller function or the same curtain controller number as the curtain controller selected in the engineering configuration interface, and the other curtain controller functions or curtain controller numbers which the curtain controller was configured to have are cancelled; the other curtain controller is operated once again, the other curtain controller is also configured to have the same curtain controller function or the same curtain controller number as the curtain controller selected in the engineering configuration interface, and the front and rear 2 curtain controllers are also configured to be 1 curtain control group; and then other curtain controllers are operated, the number of the curtain controllers of the curtain control group is increased. The second method is that all the curtain controllers have the status indication of whether the curtain controllers are configured; if the curtain controller which is not configured is operated for the first time in the state indication display, new configuration is carried out, and the state indication display configuration is successful; if the curtain controller with the successfully configured status indication display is operated once, the configuration is cancelled, and the status indication display is not configured; the unconfigured curtain controller can be set as a standby curtain controller, or set as an unconfigured curtain controller, or set as other names; the unconfigured shade controller may also be set to be the shade controller No. 0, or to be other special numbers. Whether the configured state indication is available can be distinguished by the on and off of the indicator light, can be distinguished by the flicker of the indicator light, can be distinguished by the different flicker frequencies of the indicator light, and the like.

The interlocked configuration of all the curtain control units can be changed at any time by reconfiguration, reconfiguration cancellation and the like. The hotel room electrical equipment control system may further include 1 or more air conditioner control units, 1 or more monitoring units, 1 or more dimming control units, 1 or more controllable sockets, and the like, among the plurality of distribution units.

In the hotel guest room electrical equipment control system, all the distribution units are communicated in a multi-master broadcasting mode, and the communication is implemented specifically through a program running in a microcontroller module in each distribution unit. The multi-master means that all the distribution units in the distributed wireless communication network are hosts and can actively transmit data to the distributed wireless communication network in a broadcast mode. All the distribution units are provided with a communication module, and in the same hotel room electrical equipment control system, all the communication modules transmit the data of the distribution unit to other distribution units and receive the data of other distribution units in the same mode. If no distribution unit of the distributed wireless communication network sends data outwards in a broadcast mode through the communication module, the distributed wireless communication network is in an idle state; if the distributed wireless communication network has the distributed units to send data outwards in a broadcast mode through the communication module, the distributed wireless communication network is in a non-idle state. When a certain distribution unit needs to send data outwards, the current state of the distributed wireless communication network is detected firstly; and when detecting that the distributed wireless communication network is in an idle state, the distributed unit starts to send data outwards in a broadcast mode by a communication module of the distributed unit.

Under the normal working condition, the number of the distribution units in the hotel guest room electrical equipment control system is limited, and the time-consuming time for each distribution unit to broadcast and send data is short. On one hand, the data to be sent is simple and the message is short; on the other hand, the number of operations for each distribution unit is limited, for example, operations for the touch switch unit, whether the light is turned on or off or the exhaust fan is turned on or off, will not be frequently operated, and each distribution unit needs to send data to the outside only when the status of the distribution unit changes, and therefore, it is not so many that each distribution unit needs to send data to the outside in time. Therefore, the distributed wireless communication network is basically in an idle state, and the communication load rate is extremely low; each distribution unit transmits data in a broadcast mode, and generally, no conflict is caused, namely, 2 or more distribution units on the bus transmit data in the broadcast mode simultaneously, or 2 or more distribution units transmit data in the broadcast mode simultaneously by using a wireless communication network.

In order to improve the reliability of communication, each distribution unit can repeatedly transmit the data to be broadcast and released for 1 time or more, wherein each retransmission is carried out after the interval delay time t; as with the first transmission, all repeated transmissions need to be initiated upon detecting that the distributed wireless communications network is in an idle state. Further, in order to avoid causing collision again when the distribution unit which has caused collision repeatedly sends, the specific value of the interval delay time t of the retransmission is generated in a random mode; when the retransmission is carried out for multiple times, the interval delay time t of each retransmission is generated in a random mode, namely the interval delay time of each retransmission is randomly selected. The range of the interval delay time t is not specifically required, and in general, the maximum value of the interval delay time t does not exceed 10ms, and the minimum value is greater than 0. For example, the interval delay time t can be set to randomly generate between 0.1 ms and 1 ms.

The procedure of implementing communication and interlock using multi-master broadcasting is described in example 1 described above in which a plurality of appliance switching devices in3 touch switch units shown in fig. 1 are configured in an interlocked state. 3 touch switch units, wherein 4 electrical switch devices or 4 switches are arranged in the touch switch unit 300, namely K11, K12, K13 and K14; there are 5 electrical switching devices, or 5 switches, respectively K21, K22, K23, K24, and K25 in the touch switch unit 400; the touch switch unit 500 has 3 electrical switch devices, or 3 switches, K31, K32, and K33, respectively. Assuming that the same controlled object is set at this time, the interlock configuration is performed, the controlled objects of K11, K23, and K32 are all set as room lights, and the other switches are set as other controlled objects. When the current state of the room lamp is a lamp-on state, the room lamp is turned off on the K23, the touch switch unit 400 turns off the switch driving module of the K23, and simultaneously, the related information of the room lamp is converted into data and sent to the distributed wireless communication network in a broadcast mode; after receiving the data of the touch switch unit 400, the touch switch unit 300 and the touch switch unit 500 respectively turn off the switch driving modules of K11 and K32, which are both control room lights, so as to achieve synchronization. The room access point unit reports the received information that the touch switch unit 400 controls the room light to the hotel server 705. After the other distribution units receive the information of the house lamp controlled by the touch switch unit 400, the analysis result shows that the house lamp is irrelevant to the analysis result, and the information is ignored.

The distribution units realize communication by adopting a multi-main broadcasting mode, and the distribution units form a distributed wireless communication network by adopting an ad hoc network mode. The communication modules of all the distribution units adopt wireless transceiving modules capable of realizing wireless digital communication, namely, the distribution type wireless communication network is automatically formed.

The distribution unit realizes communication by adopting a multi-main broadcasting mode, only relevant information of the distribution unit is sent when data is sent, and the sent information is irrelevant to other distribution units. For example, when the room lamp closing operation is performed at K23, the touch switch unit 400 converts the information related to the room lamp controlled by K23 into data and transmits the data to the distributed wireless communication network in a broadcast manner, and the data transmission of the touch switch unit 400 is independent of other distributed units, and more precisely, whether other switches (i.e., electrical switch devices) are configured in the interlocking state with K23. After receiving the information related to the room light controlled by K23 sent by the touch switch unit 400, the other distribution units perform corresponding processing on the information, for example, switches (i.e., electrical switch devices) for controlling the room light are also respectively provided in the touch switch unit 300 and the touch switch unit 500, so that corresponding synchronous operation is performed, and the room access point unit reports the information to the hotel server 705; if the interlock configuration is modified to change K32 to control a wall light, the touch switch unit 500 receives information about the K23 control of the room light and ignores the information.

The distribution unit realizes communication by adopting a multi-main broadcasting mode, and when the distributed wireless communication network fails or partial distribution units fail, the intact part of the distributed wireless communication network or the distributed wireless communication network consisting of the intact part of the distribution units can still work normally. Taking the example that the control objects of K11, K23, and K32 are all set as room lights to realize interlocking control as an example, when the distribution unit where K32 is located cannot communicate with other distribution units in the distributed wireless communication network, that is, the distribution unit where K32 is located fails, or a part where the distributed wireless communication network communicates with the distribution unit where K32 is located fails, although K32, K11, and K23 are configured to be in an interlocking state, the distribution unit where K32 is located is also in an independent operating state, and what is actually still in the interlocking state is K11 and K23. When the room lamp is controlled by the output of K11 or K23, the three-place control originally realized by K32, K11 and K23 is changed into the current two-place control realized by K11 and K23.

The distribution unit can adopt a master-slave mode to communicate besides a scheme of adopting a multi-master broadcasting mode to realize communication, and is specifically implemented by a program running in a microcontroller module in the distribution unit. And configuring one of the plurality of distribution units of the hotel guest room electrical equipment control system as a communication host, and configuring other distribution units as communication slaves, so that the hotel guest room electrical equipment control system realizes communication in a master-slave mode. The distribution unit configured as a communication master is only a master in terms of communication and does not play a role of centralized control.

There are various ways to configure one of the plurality of distribution units of the hotel room electrical equipment control system as a communication host.

The first way of configuring the communication host is as follows: and adopting a pre-fixed configuration mode, namely, fixedly configuring one of a plurality of distribution units of the hotel room electrical equipment control system as a communication host in advance, and configuring other distribution units as communication slaves. For example, the room access point unit 200 in the electrical equipment control system of a hotel room shown in fig. 1 is configured as a communication master, and the touch switch unit 300, the touch switch unit 400 and the touch switch unit 500 are configured as communication slaves; other distributed units added to the system shown in fig. 1 are also configured as communication slaves. Or when the plurality of distribution units of the hotel guest room electrical equipment control system are provided with the power-taking switch units, the power-taking switch units are configured as communication hosts, and other distribution units are configured as communication slaves. Or when a plurality of room access point units are arranged in a plurality of distribution units of the hotel room electrical equipment control system, one room access point unit is configured as a communication host, and other distribution units are configured as communication slaves. And so on. When the pre-fixed configuration mode is adopted, the communication program operated in the microcontroller module in the distribution unit configured as the communication master is fixed as a master communication program, and the communication program operated in the microcontroller module in the distribution unit configured as the communication slave is fixed as a slave communication program.

Configuration of the communication host in the second mode: and determining one selected configuration of a plurality of distribution units of the hotel room electrical equipment control system as a communication master machine and the other selected configurations of the distribution units as communication slave machines by adopting an engineering configuration determination mode. At this time, all the distribution units in the hotel room electrical equipment control system can be selected and configured as communication hosts or slaves; when the distribution unit is selected and configured to determine as a communication host, a communication program running in a microcontroller module in the distribution unit is a host communication program; when the distribution unit is selected and configured to determine as a communication slave, the communication program running in the microcontroller module within the distribution unit is a slave communication program. For example, the room access point unit 200 in the electrical equipment control system for hotel rooms shown in fig. 1 is configured as a communication master, and the touch switch unit 300, the touch switch unit 400 and the touch switch unit 500 are configured as communication slaves, so that the communication program running in the access point microcontroller module in the room access point unit 200 is a master communication program, and the communication program running in the switch microcontroller module in the touch switch unit 300, the touch switch unit 400 and the touch switch unit 500 is a slave communication program; the touch switch unit 300 in the electrical equipment control system for hotel guest rooms shown in fig. 1 is configured as a communication master, and the room access point unit 200, the touch switch unit 400 and the touch switch unit 500 are configured as communication slaves, so that the communication program running in the switch microcontroller module in the touch switch unit 300 is a master communication program, and the communication program running in the switch microcontroller module in the touch switch unit 400 and the touch switch unit 500 and the communication program running in the access point microcontroller module in the room access point unit 200 are slave communication programs. There are also various methods for configuring the communication host by adopting the engineering configuration determining mode, and the configuration determination can be carried out during production, and the configuration determination or the configuration modification can also be carried out on site; a computer or a special configuration tool can be accessed into an on-site hotel guest room electrical equipment control system to carry out networking unified configuration determination, or a single distribution unit can be connected with the computer or the special configuration tool to carry out off-network independent configuration determination; the configuration can also be performed by inputting a controllable level signal at the I/O terminal of the distributed-unit microcontroller module.

When the distribution units communicate in a master-slave mode, the communication host plays a role in comprehensive coordination, and the communication among all the distribution units is completed through the communication host. The data of the distribution unit where each communication slave machine is located is firstly sent to the communication host machine, and the communication host machine forwards the data to the distribution unit where each communication slave machine is located or the distribution unit where the designated communication slave machine is located; the data of the distribution unit where the communication master is located is directly sent to the distribution unit where each communication slave is located or the distribution unit where the designated communication slave is located.

The process of communication and interlock in the master-slave manner is described by the example of the foregoing example in which a plurality of appliance switch devices in3 touch switch units shown in fig. 1 are configured in the interlock state. The room access point unit 200 in the system shown in fig. 1 is configured as a communication master, and 3 touch switch units are all configured as communication slaves; the touch switch unit 300 has 4 electrical switch devices, or 4 switches, K11, K12, K13, and K14; there are 5 electrical switching devices, or 5 switches, respectively K21, K22, K23, K24, and K25 in the touch switch unit 400; the touch switch unit 500 has 3 electrical switch devices, or 3 switches, K31, K32, and K33, respectively. Assuming that the same controlled object is set at this time, the interlock configuration is performed, the controlled objects of K11, K23, and K32 are all set as room lights, and the other switches are set as other controlled objects. When the current state of the room lamp is a lamp-on state, a room lamp closing operation is performed on K23, the touch switch unit 400 closes the switch driving module of K23, after the room access point unit 200 confirms the communication authority of the touch switch unit 400 and initiates communication with the touch switch unit 400, the touch switch unit 400 converts relevant information of the room lamp to be controlled into data and transmits the data to the room access point unit 200, and the room access point unit 200 transmits the data to the distributed wireless communication network by broadcasting or respectively transmits the data to the touch switch unit 300 and the touch switch unit 500; after receiving the data of the touch switch unit 400 forwarded by the room access point unit 200, the touch switch unit 300 and the touch switch unit 500 respectively turn off the switch driving modules of K11 and K32 which are used for controlling the room lights, so as to realize synchronization; the room access point unit 200 reports the information that the touch switch unit 400 controls the room lights to the hotel server 705. If the system also has other distribution units which receive the information of controlling the house lamp by the touch switch unit 400 forwarded by the room access point unit 200, the analysis result is irrelevant to the analysis result, and the information is ignored.

The distribution unit can realize communication in a single main broadcast mode except for the scheme of realizing communication in a multi-main broadcast mode and communication in a master-slave mode, and data transmission among the distribution units is realized by specifically implementing a program running in a microcontroller module in the distribution unit. One of the plurality of distribution units of the distributed wireless communication network is configured as a coordinating master, and the other distribution units are configured as coordinating slaves. In the distributed wireless communication network, only one distribution unit has the broadcasting authority at any time, and data is sent to the distributed wireless communication network in a broadcasting mode; the broadcasting authorities of all the distribution units are comprehensively coordinated and determined by the coordination host; the broadcast authority determination method is preferably a simple rotation method, and other methods may be adopted for determination. The distribution unit configured as a coordinating host functions only to coordinate broadcasting rights and does not function as a centralized control.

When one of the plurality of distribution units of the distributed wireless communication network is configured as a coordination master and is communicated in a master-slave mode, the one of the plurality of distribution units of the distributed wireless communication network is configured as a communication master, and the communication master has a plurality of modes including a mode of fixedly configuring in advance, namely, one of the plurality of distribution units of the distributed wireless communication network is fixedly configured as a coordination master in advance, and other distribution units are configured as coordination slaves; the communication program operated in the microcontroller module in the distribution unit configured as the coordination master is fixed as a coordination master communication program, and the communication program operated in the microcontroller module in the distribution unit configured as the coordination slave is fixed as a coordination slave communication program. Determining one selected configuration of a plurality of distribution units of the distributed wireless communication network as a coordination master, and determining other selected configurations of the distribution units as coordination slaves by adopting an engineering configuration determination mode; at this time, all the distributed units in the distributed wireless communication network can be selected and configured as a coordination master or a coordination slave; when the distribution unit is selected and configured to determine as a coordination host, a communication program running in a microcontroller module in the distribution unit is a coordination host communication program; when the selected configuration of the distribution unit is determined to be the coordinating slave, the communication program running in the microcontroller module within the distribution unit is the coordinating slave communication program. There are also various methods for configuring the coordinating host by adopting the engineering configuration determining mode, and the configuration determination can be carried out during production, and the configuration determination or the configuration modification can also be carried out on site; the computer or the special configuration tool can be accessed in a field distributed wireless communication network to carry out networking unified configuration determination, and a single distribution unit can be connected with the computer or the special configuration tool to carry out off-network independent configuration determination; the configuration can also be performed by inputting a controllable level signal at the I/O terminal of the distributed-unit microcontroller module.

The procedure for implementing communication and interlocking by using a single main broadcast is described by the example shown in fig. 1 and described above. Configuring a room access point unit 200 in the system shown in fig. 1 as a coordination master, and configuring 3 touch switch units as coordination slaves; the touch switch unit 300 has 4 electrical switch devices, or 4 switches, K11, K12, K13, and K14; there are 5 electrical switching devices, or 5 switches, respectively K21, K22, K23, K24, and K25 in the touch switch unit 400; the touch switch unit 500 has 3 electrical switch devices, or 3 switches, K31, K32, and K33, respectively. At this time, the interlock arrangement is performed by encoding all the appliance switching devices, and the codes of K11, K23, and K32 are set to 007, and the other appliance switching devices are set to other codes. When the current states of K11, K23, and K32 are all on states, a closing operation is performed on K23, the touch switch unit 400 closes the switch driving module of K23, and after the room access point unit 200 confirms that the touch switch unit 400 has the broadcasting right, the touch switch unit 400 converts the information about the switch closure coded as 007 into a data broadcast and transmits the data broadcast to the distributed wireless communication network; after receiving the data sent by the touch switch unit 400, the touch switch unit 300 and the touch switch unit 500 respectively close the switch driving modules of K11 and K32 with the same code 007, so as to realize synchronization; the room access point unit reports the received information about the switch closure encoded as 007 in the touch switch unit 400 to the hotel server 705. If the system has other distribution units, after the other distribution units receive the information related to the switch closure coded as 007 in the touch switch unit 400, the information is analyzed to be irrelevant to the switch closure, and then the information is ignored.

When the hotel room electrical equipment control system is communicated in a master-slave mode, one of the plurality of distribution units of the hotel room electrical equipment control system is configured as a communication master, and the other distribution units are configured as communication slaves. All communication slave machines in the hotel room electrical equipment control system need to be registered in the communication host machine and join the distributed wireless communication network, namely the communication host machine needs to know that the distribution units configured as the communication slave machines exist in the hotel room electrical equipment control system, so that the communication host machine can coordinate and distribute communication authorities of all the communication slave machines.

When the single-master broadcast mode is adopted for communication, one of the plurality of distribution units of the distributed wireless communication network is configured as a coordination master, and the other distribution units are configured as coordination slaves. All the coordination slave machines in the hotel room electrical equipment control system need to be registered in the coordination master machine and join the distributed wireless communication network, namely the coordination master machine needs to know that the distribution units configured as the coordination slave machines exist in the hotel room electrical equipment control system, so that the coordination master machine can coordinate and distribute the broadcasting permission of all the coordination slave machines.

There are various methods for registering the communication slave in the communication master, and there are also various methods for registering the coordination slave in the coordination master, which are the same as the methods for registering the communication slave in the communication master. Hereinafter, the communication slave is simply referred to as a slave, the communication master is simply referred to as a master, the coordination slave is also simply referred to as a slave, and the coordination master is also simply referred to as a master, and methods for registering the communication slave in the communication master and registering the coordination slave in the coordination master are described. The registration refers to adding necessary information of the slave to the master, for example, adding a unit identification code or an address code of the slave to the master, so that the master can coordinate and allocate communication rights, broadcast rights and the like to all the slaves. All the distribution units are provided with unit identification codes or communication address codes for identifying the distribution units.

The first registration method comprises the following steps: registration is performed on an operation panel of a distribution unit configured as a master, and necessary information of the slave is added to the master by a panel operation.

And a second registration method: and a computer or a special registration tool is accessed into the on-site hotel guest room electrical equipment control system, and necessary information of the slave computer is added to the host computer by the computer or the special registration tool through a distributed wireless communication network.

The third registration method comprises the following steps: the distribution unit configured as a master is connected with a computer or a special registration tool, and necessary information of the slave is directly added to the master through the computer or the special registration tool.

The registration method comprises the following steps: and (4) automatic registration mode. Let the system have a slave G, and take the slave G as an example to explain the main points of the automatic registration method: the master computer communicates with the registered slave computers at a time interval not exceeding time T in a rotating or other mode; the communication with the registered slave machines includes confirming the broadcasting authority of the slave machines, or confirming the communication authority of the slave machines, or other forms of communication. And secondly, the host detects whether the registration information sent by the slave machine in a broadcasting mode exists on the distributed wireless communication network at any time, and if so, the registration information is registered in the host. And thirdly, after the slave G is powered on, waiting for the master to initiate the contact with the slave G, wherein the waiting time is T + T1. Fourthly, within the waiting time T + T1, the master initiates the contact with the slave G, and the slave G is registered in the master and the registration is finished. Within the waiting time T + T1, the master computer does not initiate the contact with the slave computer G, and the slave computer G considers that the slave computer G is not registered in the master computer, thereby initiating the automatic registration process. The automatic registration process of the slave G is to send registration information to the distributed wireless communication network in a broadcast mode, and then wait for the host to initiate contact with the slave G, wherein the waiting time is T + T1; within the waiting time T + T1, the master initiates the contact with the slave G, and then the slave G is registered in the master and the registration is finished; within the waiting time T + T1, the master does not initiate contact with the slave G, and this automatic registration of the slave G is unsuccessful. When the automatic registration of the slave machine G is not successful, the automatic registration process may be repeated multiple times, for example, 3 times.

The range of the additional waiting time T1 is not particularly required, and normally, the maximum value of the additional waiting time T1 is not more than 10ms, and the minimum value is more than 0. For example, the additional waiting time T1 can be set to randomly generate between 0.1 ms and 1 ms.

When the time T is selected, the time T is required to be larger than the time required by the master machine to contact all the slave machines once in turn, namely when the master-slave mode is adopted for communication, the communication master machine communicates with all the communication slave machines once in turn, and the time required by receiving and forwarding all the data is finished; when the single-master broadcasting mode is adopted for communication, the coordination master computer communicates with all the coordination slave computers once in turn, and all the coordination slave computers finish the time required by the broadcast transmission of data.

When the distribution unit sends data, whether the data is sent or not, namely, the driving mode of sending the data adopts one of an event driving mode and a time driving mode, or adopts the event driving mode and the time driving mode simultaneously. The event-driven mode is that when the distribution unit generates data to be sent, the data sending is started, and the data generated according to the relevant information of the distribution unit is sent to other distribution units; for example, when the touch switch unit has a switch operation, data transmission needs to be started; for example, after receiving data of a hotel server, a room access point unit needs to start data transmission; and so on. The time driving mode is that the distribution unit sends data such as state information of the unit where the distribution unit is located out periodically.

The control cores of the microcontroller modules of the distribution unit, for example, the control cores of the access point microcontroller module 701, the switch microcontroller module 301, the power-taking microcontroller module 201, the doorplate microcontroller module 601, the curtain microcontroller module 801 and the like, can be selected from microcontrollers such as a single chip microcomputer, an ARM, a DSP and the like, and can also be selected from controllers such as a CPLD and the like.

The configuration information of each distribution unit, such as switch interlock configuration information, configuration information of a host computer and a slave computer, registration information, various identification codes and address code information, and the like, which are all allowed to be modified but need to be still reserved in the power failure, is stored in a nonvolatile memory of a control core of a microcontroller module of the distribution unit or a nonvolatile memory added outside the control core of the microcontroller module in the distribution unit. For example, when the control core selects the single chip microcomputer, the modification information is stored in a nonvolatile memory of the single chip microcomputer, or is stored in a nonvolatile memory device extended from the periphery of the single chip microcomputer.

The power supply of the distribution unit can adopt a zero-live wire power supply or a single-live wire power supply according to requirements.
