All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to realize intelligent commodity inspection of the outdoor unit or the indoor unit, manual participation in the commodity inspection process is avoided, and the commodity inspection efficiency, safety and reliability are improved. As shown in fig. 3, the embodiment relates to a detection method for a multi-split air conditioner, which is used for equipment to be detected, and the equipment to be detected comprises an outdoor unit and an indoor unit; the indoor unit and the outdoor unit are communicated with the wire controller, and the detection method of the multi-split air conditioner comprises the following steps: s1, controlling the equipment to be detected and the wire controller to be electrified; s2, if the equipment to be detected successfully handshakes with the line controller, the line controller sends a signal of one mode of a heating mode and a cooling mode; s3, judging whether one mode is normally operated, if so, controlling the line controller to power off for a first time period T1, and then executing the step S4; if not, controlling the line controller to power off for a second time period T2 and then powering on, and executing steps S2 and S3; s4, controlling the power-on of the wire controller, and sending a signal of the other mode of the heating mode and the cooling mode by the wire controller; s5, judging whether the other mode is normally operated, if so, controlling the current equipment to be detected to be powered off and controlling the controller to be powered off for a second time period T2, and then executing steps S1 to S5 on the other equipment to be detected; if not, the controller is powered on again after being powered off for a second time period T2, and steps S2 to S5 are executed; wherein the first time period T1 is less than the second time period T2.
As shown in fig. 1, each of n rooms is provided with an indoor unit and a line controller, wherein the indoor unit includes an air disc for cooling and a floor heating unit for heating, the line controller communicates with the indoor unit and the outdoor unit through indoor and outdoor communication lines, the on-off of the outdoor unit and the cooling and heating can be controlled, the on-off of the air disc valve is controlled, the on-off of the floor heating valve is controlled, and the operation modes of the line controller include a heating mode and a cooling mode. When the line controller selects the cooling mode or the heating mode, the fan is operated to blow out cool air or hot air, and the water passage circuit is caused to flow in the water flow direction, so that the heating mode may be regarded as a heating (low/medium/high) air mode, and the cooling mode may be regarded as a cooling (low/medium/high) air mode. If the detection parameters fed back by the equipment to be detected in the cooling mode are all normal, the performance of the related devices in the cooling mode is all normal, and if the detection parameters fed back by the equipment to be detected in the heating mode are all normal, the performance of the related devices in the cooling mode is all normal.
The equipment to be inspected in the embodiment comprises an indoor unit and an outdoor unit, the outdoor unit can work during heating and cooling, and for the indoor unit, the air disc is used for cooling during cooling, and the indoor unit is used for heating during heating, so that detection of the air disc and the floor heating is collectively referred to as detection of the indoor unit in the embodiment. If the outdoor unit can play a role in refrigeration and heating when the outdoor unit is independently detected, a test device similar to a wind disc and a floor heating device is additionally arranged at a commodity inspection position where equipment to be detected is located according to the outdoor unit, so that the performance of the outdoor unit can be conveniently detected; similarly, if a test device similar to an outdoor unit, such as a water tank and a lift pump disposed in the water tank, needs to be additionally disposed at a commercial inspection position according to the wind pan or the floor heating when the independent detection wind pan can perform a cooling function, it is possible to realize water circulation in the waterway circuit. In this embodiment, only the detection of the outdoor unit and the indoor unit is concerned, and the detection of the unit for detecting the additional configuration of the outdoor unit and the detection of the unit for detecting the additional configuration of the indoor unit are not involved, and it is assumed that these test units are all working normally.
The specific detection processes of the outdoor unit and the indoor unit are described in detail as follows:
s1: controlling the equipment to be detected and the wire controller to be electrified;
specifically, at the time of starting the commodity inspection, the equipment to be inspected is transported to the commodity inspection position. And at the commodity inspection position, powering on the equipment to be inspected and the wire controller.
In this embodiment, treat through the power control cabinet and examine equipment and drive-by-wire ware power-on or outage to power control cabinet and off-premises station, wind dish and ground warm up communication connection for obtain the parameter that detects after off-premises station, wind dish and the operation of ground warm, can monitor whether the off-premises station normally operates under the refrigeration mode of heating, whether the wind dish normally operates under the refrigeration mode and ground warm up normally operates under the heating mode.
S2, if the equipment to be detected successfully handshakes with the line controller, the line controller sends a signal of one mode of a heating mode and a cooling mode;
after the equipment to be detected and the wire controller are powered on, the wire controller and the equipment to be detected are subjected to handshake, if the handshake is successful, the wire controller sends a signal of a heating mode, for example, and feeds back parameters detected when the equipment to be detected operates in the heating mode to the power control cabinet; if the handshake is unsuccessful, the line controller continues to handshake with the equipment to be tested, a period of time can be set at the point, and if the handshake is unsuccessful within a period of time, a communication fault prompt can be sent.
Of course, before the line controller sends out the heating mode or the cooling mode, it is necessary to ensure the normal circulation of the water circuit, which is a precondition for realizing heating or cooling.
Aiming at the winddisk and the floor heating, the lifting pump and the water tank can be additionally configured and the lifting pump is tested to work normally so as to ensure that the circulation of a waterway loop is normal, and the lifting pump does not belong to one part of the indoor unit, so that the lifting pump is not required to be controlled by a wire controller, and the lifting pump can be tested in advance before the winddisk is tested or the floor heating is carried out.
The outdoor unit further includes step S21: before the online controller sends a signal of one of a heating mode and a cooling mode, whether a water pump in the outdoor unit is normally opened or closed is determined; specifically, after the line controller successfully shakes hands with the outdoor unit, the line controller immediately sends an operation instruction of forced operation of the water pump, and after a period of time (for example, 10 seconds), the line controller sends a stop instruction of forced stop of the water pump, so as to determine whether the opening and closing of the water pump are normal.
S3, judging whether one mode is normally operated, if so, controlling the line controller to power off for a first time period T1, and then executing the step S4; if not, after the control line controller is powered off for a second time period T2, the control line controller is powered on and executes the steps S2 and S3;
when the operation parameters received by the power control cabinet are all normal, the performance of the current equipment to be detected in the heating mode is normal, at this time, the power control cabinet cuts off the power of the line controller for a first time period T1 so as to automatically switch from the heating mode to the cooling mode, and how to realize the mode automatic switching will be described in detail as follows.
Specifically, in this embodiment, after the line controller is powered off, the power supply VCC (e.g., +5V dc power supply) of the transient stop circuit of the line controller shown in fig. 2 is powered down, the capacitor C1 is discharged, the level output from the output terminal PL of the transient stop circuit connected to the line controller does not immediately drop to zero in a short time, a preset voltage Vset is preset, a period of time during which the voltage Vpl at PL decreases from the start of power-off to Vset becomes the transient stop time of the line controller (or, Vpl > = the transient stop of the line controller when Vset is also called), that is, a first time period T1, and after a second time period (called the long stop time of the line controller, or the long stop time of the line controller when Vpl < Vset) longer than the first time period T, the magnitude of Vpl decreases from Vset 1 becomes inversely proportional to the magnitude of Vset, the value of T is longer than the value of T1, and the larger the value of Vset is the shorter the value of T1, in this implementation. Therefore, the power-off length of the power controller control line controller is set by setting the size of the Vset, so that when the power controller is powered on again after the power controller is stopped for the first time period T1, the line controller can acquire Vpl = Vset, and after the line controller and the device to be tested handshake again succeeds, the line controller sends a cooling mode signal to the device to be tested according to Vpl = Vset to control the device to be tested to automatically switch to a cooling mode. Therefore, the mode is automatically switched by controlling the instant stop time of the wire controller and the instant stop of the instant stop circuit of the wire controller through the power control cabinet.
When the operating parameters received by the power control cabinet are abnormal, the performance of the current equipment to be detected in the heating mode is abnormal, and at the moment, the power control cabinet cuts off the power of the line controller for a second time period T2 so as to detect the heating mode of the equipment to be detected again. Specifically, the power-off second time period T2 of the power control cabinet is called long stop, and the time of the second time period T2 is longer than the first time period T1, so that Vpl < Vset, therefore, when the power control cabinet powers on the line control device again after the power control cabinet controls the power off second time period T2, the line control device can acquire Vpl < Vset, so as to control the device to be tested to detect again according to the signal line control device, and confirm whether the device to be tested is qualified again. Therefore, the long stop time of the wire controller and the long stop of the instantaneous long stop circuit of the wire controller are controlled by the power control cabinet, so that the current device to be detected is checked again.
Can wait to examine equipment and carry out unusual warning when parameter is unusual appearing, assume at least twice to operate unusually under the same kind of mode, then can be manual when power control cabinet control line controller long-term stops to examine equipment outage to operating personnel overhauls the trouble.
S4, controlling the power-on of the wire controller, and sending a signal of the other mode of the heating mode and the cooling mode by the wire controller;
and after the power controller cuts off the power of the line controller for a first time period T1 (namely the line controller is instantly stopped), controlling the line controller to be powered on, acquiring the voltage Vpl = Vset at the PL, controlling the sending refrigeration mode at the moment, and sending the detected parameters to the power control cabinet when the equipment to be detected runs in the refrigeration mode.
S5, judging whether the other mode is normally operated, if so, controlling the current equipment to be detected to be powered off and controlling the controller to be powered off for a second time period T2, and then executing steps S1 to S5 on the other equipment to be detected; if not, after the control line controller is powered off for a second time period T2, the control line controller is powered on and executes steps S2 to S5.
When the operation parameters of the heating mode received by the power control cabinet are normal, the mode is automatically switched to the cooling mode through the instant stop of the instant long stop circuit, when the cooling operation parameters received by the power control cabinet are normal, the performance of the current equipment to be detected in the cooling mode is normal, at the moment, the power control cabinet controls the wire controller and the equipment to be detected to be powered off, and the commodity inspection process aiming at the current equipment to be detected is completed.
In fact, in a period from the completion of the current commodity inspection of the equipment to be inspected to the arrival of another equipment to be inspected at the commodity inspection position, since the operation worker needs to perform the implementation of the actions such as the bar code, the certificate and the like, the power-off time of the line controller is longer, and the power-off time is greater than or equal to the second time period T2, which can be regarded as the long stop of the line controller. The second time period T2 may be set appropriately according to the speed, tempo, and the like of the commodity inspection. When the power supply control cabinet powers on the line controller again after the power supply control cabinet powers off the line controller for the second time period T2, the line controller can acquire Vpl < Vset, and meanwhile, after the next device to be detected is powered on, the line controller handshakes the next device to be detected and restarts the commodity inspection process.
When the operating parameters of the heating mode received by the power control cabinet are abnormal, the performance of the current equipment to be detected in the heating mode is abnormal, at the moment, the power control cabinet cuts off the power of the line controller for a second time period T2 (namely, the line controller is in long stop), when the line controller is electrified again, the line controller handshakes the current equipment to be detected again, Vpl < Vset can be collected, meanwhile, the commodity inspection is carried out on the current equipment to be detected again after the handshake is successful, and whether the equipment to be detected is qualified is confirmed again.
In this embodiment, can wait to examine equipment and appear parameter abnormal and carry out unusual warning when unusual, when unusual warning appears, power control cabinet control line accuse ware carries out long stop, for example, when examining the outdoor unit commodity, if the outdoor unit transmits the parameter that detects to power control cabinet unusual, power control cabinet control line accuse ware carries out long stop and controls alarm circuit and sends the suggestion of reporting to the police to operating personnel in time maintains. Or when the alarm prompt action is performed twice or more, the power supply control cabinet can stop the wire controller for a long time, meanwhile, an operator can manually power off the outdoor unit, and after the maintenance is completed, the outdoor unit and the wire controller can be manually controlled to be powered on, and the commodity inspection process is restarted.
Therefore, the long stop time of the wire controller and the long stop of the instantaneous long stop circuit of the wire controller are controlled by the power control cabinet, so that the current commodity inspection of the equipment to be inspected is realized again or the commodity inspection of the next equipment to be inspected is realized.
In this embodiment, by using a communication protocol between the line controller and the device to be checked, in a message sent after the handshake between the line controller and the device to be checked is successful, a commodity inspection flag is set in the format of the message sent by the line controller, for example, when a bit is set to "1", it indicates that the message is in a commodity inspection state, and when the bit is set to "0", it indicates that the message is not in the commodity inspection state.
In the whole commodity inspection process, the wire controller is used for automatically sending a command to the equipment to be inspected, manual operation is not needed, the instantaneous stop time and long stop time parameters of the power controller and the instantaneous and long stop circuit carried by the wire controller are used for controlling, intelligent control over the equipment to be inspected is achieved, commodity inspection efficiency and safety and reliability are improved, and hardware cost is not increased.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
