Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flow chart of an apparatus state detection method according to an embodiment of the present application, and as shown in fig. 1, the apparatus state detection method includes the following steps:
s101, obtaining a remote control state of the equipment, wherein the remote control state comprises the following steps: and (4) allowing.
It will be appreciated that when the remote control state is enabled, the device control state is a remote control state, i.e. it indicates that the device is enabled to be controlled by remote control means, and when the device is under remote control, local control of the device is disabled.
In one application scenario, taking an air conditioning unit as an example, the air conditioning unit is configured with a remote switch control device. Through the operation of the remote switch control device, the air conditioning unit can be remotely controlled or locally controlled. For example, the air conditioning unit is remotely controlled through a remote terminal, or the air conditioning unit is locally controlled through an upper computer of the air conditioning unit. When the air conditioning unit is under remote control, the local control of the air conditioning unit is forbidden, namely the upper computer is forbidden to control the air conditioning unit at the moment, and the air conditioning unit can be controlled through the remote terminal.
When the remote control state is allowed, the operation of the equipment comprises the following steps: and performing on-off operation on the equipment and the like. For example, the air conditioning unit is controlled to be turned on or off through the remote terminal.
In one embodiment, the obtaining the remote control state of the device includes:
receiving first communication data, wherein the first communication data comprise a remote control state of equipment;
and reading the remote control state of the equipment from the first communication data.
In a specific application, the remote control state of the equipment is determined by operating the remote switch control device, so that the first communication data carrying the remote control state of the equipment can be directly sent by the remote switch control device.
For example, when the remote switch control device is operated to determine that the remote control state of the equipment is allowed, the remote switch control device sends first communication data carrying that the remote control state of the equipment is allowed to the equipment state detection device, and the equipment state detection device can obtain that the remote control state of the equipment is allowed by reading the received first communication data.
And S102, when the remote control state is allowed, carrying out equipment point state detection on the equipment, and determining the equipment state according to the detection result.
It will be appreciated that when the remote control state is enabled, the remote terminal sends an instruction to the device, which responds to the instruction by a change in state of the device point to cause the device to perform a corresponding action. Accordingly, the device state detection means determines the state of the device by detecting whether the state of the device point has changed.
In one embodiment, the performing device dot state detection on the device includes:
detecting a switching state of a switching point of the device.
In an application scenario, taking an air conditioning unit as an example, for example, a remote terminal sends a power-on instruction to the air conditioning unit, a dry contact corresponding to the power-on instruction in the air conditioning unit is closed, and the air conditioning unit executes power-on in response to the closed dry contact. When determining whether the air conditioning unit is really turned on, the equipment state detection device determines whether the dry contact is really closed.
In practical applications, the dry contact may be a device contact having no polarity between contacts such as relay contacts.
Fig. 2 is a schematic flowchart illustrating a process of detecting a switching state of a switching point of a device according to an embodiment of the present application; as shown in fig. 2, the detecting the switching state of the switching point of the device includes:
s201, confirming the pin state of a switch point of the equipment;
s202, when the pin state is valid, acquiring data corresponding to the pin in a register;
s203, determining the switching state of the switching point according to the data value of the data.
In a particular application, a pin of the register may be connected to a switch point of the device and configured to read a valid pin, and then the switch state of the switch point is determined by the reading of the pin. As shown in fig. 3, fig. 3 is a schematic flow chart of reading a state of a switch point pin by a register according to an embodiment of the present application, where the step of reading the state of the switch point pin by the register includes:
s31, confirming that the register pin corresponding to the equipment switch point is an effective pin;
s32, acquiring data corresponding to the pins in the register;
s33, judging the state of the register according to the data value of the data, and executing the step S34 if the state of the register is judged to be set to 1; if the status of the register is set to 0, go to step S35;
s34, the input of the register pin is high level;
s35, the input of the register pin is low.
It is understood that in S32, the data corresponding to the pin should be character string data, such as binary character string data, and the state of the register can be determined according to the binary character string data. For example, if the state of the register is determined to be set to 1 according to the data value, it is determined that the input of the register pin corresponding to the switch point is a high level, and accordingly, it is determined that the switch state of the switch point is a conducting state; and if the state of the register is set to be 0 according to the data value, determining that the input of the register pin corresponding to the switch point is low level, and correspondingly determining that the switch state of the switch point is an off state.
It will be appreciated that the device point state may be characterized not only by the switch state of the switch point, but also by the pin state of the processing device, including registers and the like.
In summary, in the above embodiment, the remote control state is determined first, then the device point state is detected when the remote control state is determined to be allowable, the device state is determined according to the detection result, and a limitation is formed by the remote control state being allowable to detect the device point state, so that a problem that the program efficiency is lowered due to data reading when the device point state is detected under an unnecessary condition can be avoided. Therefore, the purposes of improving the quality of the detection program and increasing the running speed of the program can be achieved.
In the foregoing embodiments, the device status is not limited to the on/off status of the device, and may be other action status situations of the device. For example, the switching point is not limited to the dry contact point because of the opening/closing operation state of the valve, and may be a switching point such as a valve that reflects the operation state of the device.
Fig. 4 is a schematic flowchart of a device status detection method according to another embodiment of the present application, and as shown in fig. 4, in S101, the remote control status further includes: forbidding;
the equipment state detection method also comprises the following steps:
s103, receiving second communication data when the remote control state is forbidden, and determining the equipment state according to the state data in the second communication data.
In one embodiment, the second communication data is sent by an upper computer, and the upper computer is used for controlling the equipment when the remote control state is forbidden.
It can be understood that, when the remote control state is forbidden, the remote terminal cannot control the device, and the device can be controlled through the upper computer, for example, the device is controlled to be turned on or turned off through the upper computer.
In an application scenario, taking an air conditioning unit as an example, the upper computer is connected with the air conditioning unit through a communication bus. When the remote control state is forbidden, the air conditioning unit can be controlled by the upper computer at the moment, the action instruction of the unit is issued by the upper computer through the communication bus, and the real-time state data of the corresponding air conditioning unit when the action is executed is also uploaded to the upper computer through the communication bus. Under the condition, the equipment state of the air conditioning unit can be determined according to the state data in the communication data of the upper computer only by receiving the communication data of the upper computer. For example, the upper computer sends a starting-up instruction to the air conditioning unit through the communication bus, starting-up data for the air conditioning unit to start up is also sent to the upper computer through the communication bus, the device state detection device receives the communication data sent by the upper computer and carries the starting-up data, and the state of the device can be determined according to the starting-up data carried in the communication data.
It can be understood that, when the remote control state is disabled, the device state detection apparatus may determine the state of the device by receiving the communication data sent by the upper computer, and if the device state detection apparatus detects the device point state of the device, on one hand, it is redundant to detect the device point state, and the detected data becomes unnecessary data, and on the other hand, when the remote control state is disabled, the reading process of the register pin may reduce the program efficiency in the process of detecting the device point state of the device.
According to the technical scheme of the embodiment, when the remote control state is allowed, the equipment point state detection is carried out on the equipment, the equipment state is determined according to the detection result, when the remote control state is forbidden, the second communication data is received, and the equipment state is determined according to the state data in the second communication data, so that the equipment is selectively detected according to the remote control state, particularly when the remote control state is forbidden, the equipment state is determined by reading the communication data of the upper computer, reading of invalid data is avoided, the quality of a detection program is improved, and the running speed of the program is increased.
In a particular application, whether remote or local, after the device state is executed, the device executes the corresponding device logic. For example, after the air conditioning unit is started, cooling, heating or defrosting and the like are performed according to the ambient temperature, so that various functions of the air conditioning unit can be achieved by executing corresponding logic. Therefore, the device status detection method of the present application may further include: and acquiring corresponding device logic data after the device state is executed so as to further perfect the detection of the device.
Fig. 5 is a schematic structural diagram of an apparatus state detection device according to an embodiment of the present application, and as shown in fig. 5, the apparatus state detection device 5 includes:
an obtaining module 51, configured to obtain a remote control state of the device, where the remote control state includes: allowing;
a first determining module 52, configured to perform device point state detection on the device when the remote control state is allowed, and determine a device state according to a detection result.
With regard to the above embodiment, it can be understood that, when the remote control state is enabled, the device control state is a remote control state, that is, it indicates that the device is enabled to be controlled by a remote control manner, and when the device is under remote control, the local control of the device is disabled.
In one application scenario, taking an air conditioning unit as an example, the air conditioning unit is configured with a remote switch control device. Through the operation of the remote switch control device, the air conditioning unit can be remotely controlled or locally controlled. For example, the air conditioning unit is remotely controlled through a remote terminal, or the air conditioning unit is locally controlled through an upper computer of the air conditioning unit. When the air conditioning unit is under remote control, the local control of the air conditioning unit is forbidden, namely the upper computer is forbidden to control the air conditioning unit at the moment, and the air conditioning unit can be controlled through the remote terminal.
When the remote control state is allowed, the operation of the equipment comprises the following steps: and performing on-off operation on the equipment and the like. For example, the air conditioning unit is controlled to be turned on or off through the remote terminal.
In an embodiment, as shown in fig. 6, fig. 6 is a schematic structural diagram of an obtaining module provided in an embodiment of the present application, where the obtaining module 51 includes:
the first receiving submodule 511 is configured to receive first communication data, where the first communication data includes a remote control state of the device;
a first reading submodule 512, configured to read a remote control state of the device from the first communication data.
In a specific application, the remote control state of the equipment is determined by the operation of the remote switch control device. Thus, in one embodiment, the first communication data may be transmitted directly by the remote switch control device.
For example, when the remote switch control device is operated to determine that the remote control state of the equipment is allowed, the remote switch control device sends first communication data carrying that the remote control state of the equipment is allowed to the equipment state detection device 5, and the equipment state detection device 5 can obtain that the remote control state of the equipment is allowed by reading the received first communication data.
When the remote control state is allowed, the remote terminal can send an instruction to the device, the device responds to the instruction through the state change of the device point so as to enable the device to execute corresponding actions, and accordingly, the device state detection device 5 determines the state of the device by detecting whether the state of the device point changes or not.
In one embodiment, the performing device dot state detection on the device includes:
detecting a switching state of a switching point of the device.
In an application scenario, taking an air conditioning unit as an example, for example, a remote terminal sends a power-on instruction to the air conditioning unit, a dry contact corresponding to the power-on instruction in the air conditioning unit is closed, and the air conditioning unit executes power-on in response to the closed dry contact. When determining whether the air conditioning unit is really opened, the determination needs to be carried out by detecting whether the dry contact is really closed.
In practical applications, the dry contact may be a device contact having no polarity between contacts such as relay contacts.

the first judging submodule 521 is used for judging the pin state of a switch point of the equipment;
a first obtaining submodule 522, configured to obtain, when the pin status is valid, data corresponding to the pin in the register;
the first determining submodule 523 is configured to determine a switching state of the switching point according to a data value of the data.
In a particular application, a pin of the register may be connected to a switch point of the device and configured to read a valid pin, and then the switch state of the switch point is determined by the reading of the pin. As shown in fig. 3, fig. 3 is a schematic flow chart of reading a state of a switch point pin by a register according to an embodiment of the present application, where the step of reading the state of the switch point pin by the register includes:
s31, confirming that the register pin corresponding to the equipment switch point is an effective pin;
s32, acquiring data corresponding to the pins in the register;
s33, judging the state of the register according to the data value of the data, and executing the step S34 if the state of the register is judged to be set to 1; if the status of the register is set to 0, go to step S35;
s34, the input of the register pin is high level;
s35, the input of the register pin is low.
It is understood that in S32, the data corresponding to the pin should be character string data, such as binary character string data, and the state of the register can be determined according to the binary character string data. For example, if the state of the register is determined to be set to 1 according to the data value, it is determined that the input of the register pin corresponding to the switch point is a high level, and accordingly, it is determined that the switch state of the switch point is a conducting state; and if the state of the register is set to be 0 according to the data value, determining that the input of the register pin corresponding to the switch point is low level, and correspondingly determining that the switch state of the switch point is an off state.
It will be appreciated that the device point state may be characterized not only by the switch state of the switch point, but also by the pin state of the processing device, including registers and the like.
In summary, in the above embodiment, the remote control state is determined first, then the device point state is detected when the remote control state is determined to be allowable, the device state is determined according to the detection result, and a limitation is formed by the remote control state being allowable to detect the device point state, so that a problem that the program efficiency is lowered due to data reading when the device point state is detected under an unnecessary condition can be avoided. Therefore, the purposes of improving the quality of the detection program and increasing the running speed of the program can be achieved.
In the foregoing embodiments, the device status is not limited to the on/off status of the device, and may be other action status situations of the device. For example, the switching point is not limited to the dry contact point because of the opening/closing operation state of the valve, and may be a switching point such as a valve that reflects the operation state of the device.
