[Effects of the Invention]

[0009] According to the present disclosure, it is possible to realize more appropriate startup control by taking into consideration the usage environment and operating temperature conditions of precision equipment. [Brief explanation of the drawings]

[0010] [Figure 1] FIG. 1 is a block diagram showing an example of the configuration of a projector according to an embodiment of the present invention. [Figure 2] 1 is a flowchart of a startup process according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0011] (Background to the content of each embodiment) In recent years, precision instruments designed for various indoor and outdoor environments have become widespread. Projectors, which are video projection devices, are an example of such precision instruments. For example, if a projector is installed and used outdoors, sunlight heats the housing during the day, warming its internal components. Meanwhile, at night or during certain seasons, projectors may be used in environments where temperatures can drop below freezing. In such environments, a range of temperatures occurs in the operating environment, and each component within the projector is exposed to these temperature fluctuations. Meanwhile, precision instruments, due to their configuration, are required to have guaranteed operating temperatures (upper and lower limits) to ensure proper operation. When operating precision instruments in environments where temperature fluctuations occur, the start of operation, i.e., startup control, must be performed taking into account the operating temperatures specified for the precision instrument.

[0012] For example, Patent Document 1 focuses on temperature control of the light source lamp in a projector, but does not consider the temperature inside the housing or how to handle it at low temperatures. Also, Patent Document 2 describes fan control, but does not fully consider the behavior of the guaranteed operating temperatures for each part inside the device at startup.

[0013] Therefore, as one embodiment of the present invention, startup control will be described assuming a precision device that may be installed in an environment where the ambient temperature and device temperature may change. In this example, a projector will be used as an example of the precision device, but the present invention is not limited to this. It is clear that the startup control according to the present invention can be applied to any precision device that is intended to be used in an environment where the temperature changes widely.

[0014] Hereinafter, with reference to the accompanying drawings, detailed descriptions will be given of embodiments specifically disclosing the precision instrument, projector, startup control method, and program according to the present disclosure. However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims.

[0015] <First Embodiment> [System Configuration] 1 is a block diagram showing an overview of a projector 100, which is an example of a precision instrument according to this embodiment. Projector 100 includes, within its housing, a control unit 101, a storage unit 102, a temperature sensor 103, a cooling mechanism 104, a light source unit 105, an optical system 106, a power supply unit 107, and an external interface 108. These components are configured to be able to cooperate with each other via an internal interface (not shown).

[0016] The control unit 101 may be configured using, for example, a central processing unit (CPU), a graphical processing unit (GPU), a micro processing unit (MPU), a digital signal processor (DSP), or a field-programmable gate array (FPGA). The control unit 101 realizes functions described below by, for example, reading and executing various data and programs stored in the storage unit 102. The storage unit 102 is a storage unit for storing various data, programs, etc., and may be configured from, for example, a volatile / non-volatile storage device such as a random access memory (RAM), a read only memory (ROM), or a hard disk drive (HDD).

[0017] The temperature sensor 103 measures the temperature at any position within the projector 100. Multiple temperature sensors 103 may be used, each measuring the temperature at a different position or location. In particular, the temperature sensor 103 is configured to measure the temperature of a location that is highly affected by temperature changes at each location provided in the projector 100. For example, the light source included in the light source unit 105, the prism, sensor, and liquid crystal panel included in the optical system 106 are easily affected by high temperatures, so the positions at which the temperature is measured may be determined with a focus on these. Similarly, the Digital Mirror Device (DMD) included in the optical system 106 is easily affected by low temperatures, so the positions at which the temperature is measured may be determined with a focus on these.

[0018] The cooling mechanism 104 is a mechanism for cooling the temperature inside the projector 100. The cooling mechanism 104 may be configured by combining, for example, a fan, a cooling pump, a coolant, etc. Alternatively, a separate cooling mechanism 104 may be provided for each part of the projector 100.

[0019] The light source unit 105 is a light source used for image projection by the projector 100. The light source unit 105 includes, for example, a laser diode (LD). The light source unit 105 can raise the temperature of the optical system by irradiating the optical system with light. In other words, the light source unit 105 also functions as a heating mechanism for a predetermined portion. The degree of heating may depend on the configuration of the projector 100, and is not particularly limited, but is controlled so as to be compatible with the heating operation described below.

[0020] The optical system 106 is used for image projection by the projector 100, and includes lenses, prisms, mirrors, conversion elements, etc. The components and arrangement of the optical system 106 may vary depending on the specifications of the projector 100, etc.

[0021] A power supply unit 107 provides power for the operation of the projector 100 by an external power supply or an internal battery (not shown).

[0022] The external interface 108 is communicably connected to an external device (not shown) via a network (not shown), and is an interface for receiving image data of the projection target, control instructions, etc., and transmitting various information. The communication standard of the external interface 108 is not particularly limited, and it may be wired or wireless.

[0023] Projector 100 according to this embodiment may be installed in various positions, such as suspended from the ceiling, portrait orientation, etc. Projector 100 is configured to be usable both indoors and outdoors.

[0024] Precision equipment such as projector 100 typically has a guaranteed operating temperature as one of its operating conditions. To ensure proper operation, the temperature of the surrounding environment and the temperatures of components within the device must be within the range of upper and lower limits specified as the guaranteed operating temperature. Even if the temperature deviates from the guaranteed operating temperature, the device may still operate, but accuracy may decrease or it may cause a malfunction.

[0025] For example, consider a case where the upper limit of the guaranteed operating temperature is 50°C and the lower limit is -20°C. For example, when projector 100 is exposed to direct sunlight outdoors, the temperature inside the cabinet of projector 100 may exceed 50°C. Furthermore, in an environment below freezing, the liquid substance provided inside projector 100 (for example, the liquid cooling agent in cooling mechanism 104) may freeze. The startup control of projector 100 according to this embodiment will be described assuming such an environment outside the range of guaranteed operating temperatures and events that may occur in that environment.

[0026] [Processing flow] 2 is a flowchart of startup control of projector 100 according to this embodiment. This processing flow may be realized, for example, by control unit 101 reading and executing a program stored in storage unit 102. This processing flow is also executed, for example, when a user issues a power-on instruction to projector 100 by pressing a power button (not shown) or by remote control.

[0027] In this embodiment, projector 100 is configured to be capable of starting up each component in a stepwise manner. Here, the description will be given assuming that, in response to receiving a power-on instruction, control unit 101 shown in FIG. 1 is first started up to be operable.

[0028] In response to receiving a power-on instruction, the control unit 101 activates the temperature sensor 103 and acquires temperature information at a predetermined position (step S201). The position or location at which the temperature is measured by the temperature sensor 103 is not particularly limited, but for example, the ambient temperature of the projector 100 or the temperature of a location that is significantly affected by temperature changes may be measured. For simplicity of explanation, the processing flow using one piece of temperature information measured by the temperature sensor 103 will be described here. Therefore, when the startup processing is executed using temperature information from multiple positions, the following processing may be similarly performed based on the respective measurement results.

[0029] The control unit 101 detects whether the internal temperature indicated by the temperature information detected by the temperature sensor 103 is equal to or lower than the threshold T high1 Greater than or equal to the threshold T low1 It is determined whether the threshold T high1 and threshold T low1 is assumed to be predetermined. For example, the threshold T high1 may be set to 60°C. Threshold T low1 may be set to −30° C. In this embodiment, the threshold T high1 and threshold T low1 The threshold T sets a value outside the guaranteed operating temperature of the projector 100. high1 exceeds the threshold T low1 If a temperature below the threshold T is measured, it is assumed that the internal temperature of the projector 100 cannot be adjusted to within the guaranteed operating temperature range by heating or cooling, or that it would take too much time to adjust it. high1 Greater than or equal to the threshold T low1 If the temperature inside the refrigerator is smaller than the threshold T high1 Less than or equal to threshold T low1 If so (step S202: NO), the process of the control unit 101 proceeds to step S203.

[0030] The control unit 101 detects whether the internal temperature indicated by the temperature information detected by the temperature sensor 103 is equal to or lower than the threshold T high2 It is determined whether the threshold T high2 is predefined, and T high1 (T high1 >T high2 ) For example, the threshold T high2 can be set to 50°C. high2 may be equal to the upper limit of the guaranteed operating temperature. high2 If the temperature inside the refrigerator is greater than the threshold T high2If it is equal to or less than this (step S203: NO), the process of the control unit 101 proceeds to step S207.

[0031] The control unit 101 activates the cooling mechanism 104 (step S204). This operation attempts to perform a cooling operation so that the temperature inside the chamber of the projector 100 falls below the upper limit of the guaranteed operating temperature. If the cooling mechanism 104 is composed of multiple parts, the cooling mechanisms 104 may be activated in stages or all at once. Also, only one of the multiple parts of the cooling mechanism 104 may be activated depending on the location where the temperature is measured by the temperature sensor 103. The control unit 101 also starts measuring the elapsed time since the cooling mechanism 104 was activated.

[0032] The control unit 101 measures the temperature information at the predetermined position again using the temperature sensor 103 and sets the threshold T high2 In other words, the control unit 101 monitors whether the internal temperature of the refrigerator falls below the upper limit temperature of the guaranteed operating temperature due to the cooling operation of the cooling mechanism 104. high2 If the temperature inside the refrigerator is greater than the threshold T high2 If it is equal to or less than this (step S205: NO), the process of the control unit 101 proceeds to step S211.

[0033] The control unit 101 determines whether a predetermined time has elapsed since the cooling mechanism 104 was activated (step S206). The predetermined time used here is assumed to be predetermined. If the predetermined time has elapsed (step S206: YES), the control unit 101 proceeds to step S212. On the other hand, if the predetermined time has not elapsed (step S206: NO), the control unit 101 returns to step S205 and repeats the process. In this case, the cooling operation by the cooling mechanism 104 and the temperature monitoring are continued. At this time, if the cooling mechanism 104 is capable of changing the cooling operation in stages, the intensity of the cooling operation may be increased. Alternatively, the operation of the cooling mechanism 104 may be switched based on the trend of temperature change (for example, a gradual decrease in temperature).

[0034] The control unit 101 detects whether the internal temperature indicated by the temperature information detected by the temperature sensor 103 is equal to or lower than the threshold T low2 It is determined whether the threshold T low2 is predefined, and T low1 (T low1 <T low2 ) For example, the threshold T low2 can be set to -20°C. low2 may be equal to the lower limit of the guaranteed operating temperature. low2 If the temperature inside the refrigerator is smaller than the threshold T low2 If so (step S207: NO), the process of the control unit 101 proceeds to step S211.

[0035] The control unit 101 activates the light source unit 105 (step S208). This operation attempts to heat the chamber of the projector 100 so that the internal temperature exceeds the lower limit of the guaranteed operating temperature. The heating here may be performed by irradiating light or by driving a mechanism. If there are other parts in addition to the light source unit 105 that can be used to raise the internal temperature of the chamber of the projector 100, these parts may also be used. The control unit 101 also starts measuring the elapsed time since the light source unit 105 was activated.

[0036] The control unit 101 measures the temperature information at the predetermined position again using the temperature sensor 103 and sets the threshold T low2 In other words, the control unit 101 monitors whether the inside temperature of the refrigerator exceeds the lower limit temperature of the guaranteed operating temperature due to the heating operation of the light source unit 105. low2 If the temperature inside the refrigerator is smaller than the threshold T low2 If so (step S209: NO), the process of the control unit 101 proceeds to step S211.

[0037] The control unit 101 determines whether a predetermined time has elapsed since the light source unit 105 was activated (step S210). The predetermined time used here is assumed to be predetermined. The predetermined time here may be the same as or different from the process in step S206. If the predetermined time has elapsed (step S210: YES), the control unit 101 proceeds to step S212. On the other hand, if the predetermined time has not elapsed (step S210: NO), the control unit 101 returns to step S209 and repeats the process. In this case, the heating operation by the light source unit 105 and the temperature monitoring are continued. At this time, if the light source unit 105 is capable of changing the heating operation in stages, the intensity of the heating operation may be increased. Alternatively, the operation of the light source unit 105 may be switched based on the trend of temperature change (for example, a gradual increase in temperature).

[0038] The control unit 101 determines that the temperature inside the cabinet of the projector 100 has fallen within the range of the guaranteed operating temperature, and starts up the entire projector 100. If any part has already been started up for temperature adjustment, the other parts are started up. Then, this processing flow ends.

[0039] The control unit 101 determines that the temperature inside the cabinet of the projector 100 is outside the range of the guaranteed operating temperature, and stops the startup and performs a shutdown. In this case, the control unit 101 may notify the user that startup is not possible due to the temperature by, for example, flashing a lamp (not shown). Then, this processing flow ends.

[0040] In the above description, one range has been used as an example of the guaranteed operating temperature. However, this is not limiting, and at least one of an upper limit temperature and a lower limit temperature as the guaranteed operating temperature may be set for each of the various components provided in projector 100. The temperatures of these components themselves or their surroundings may then be measured by temperature sensor 103, and a determination related to startup control as shown in FIG. 2 may be made. In this case, it is desirable to start up the entire projector 100 after it has been determined that the temperatures of all parts are within the guaranteed operating temperature range.

[0041] As described above, a precision device (e.g., 100) according to this embodiment includes a temperature sensor (e.g., 103), a cooling mechanism (e.g., 104) for cooling the interior of the precision device, a heating mechanism (e.g., 105) for heating the interior of the precision device, and a control unit (e.g., 101) for controlling the operation of the precision device. When the control unit receives an instruction to start the precision device, it acquires the temperature inside the precision device using the temperature sensor, and activates the cooling mechanism and heating mechanism to control the temperature to be within a predetermined range, and then starts the precision device. This configuration makes it possible to achieve more appropriate startup control by taking into account the usage environment and operating temperature conditions of the precision device.

[0042] In the precision device according to the present embodiment, the control unit determines whether the temperature acquired by the temperature sensor is within the upper limit temperature of a predetermined range (for example, T high2 ) above a first temperature (e.g., T high1), startup is stopped. With this configuration, if the temperature of the precision equipment exceeds the guaranteed operating temperature by a certain amount, startup can be stopped without performing cooling operations. This makes it possible to stop startup if it takes time to start up even after cooling operations have been performed, or if the temperature is not suitable for startup.

[0043] In the precision device according to the present embodiment, the control unit determines whether the temperature acquired by the temperature sensor is below the lower limit temperature of a predetermined range (for example, T low2 ) at a second temperature (e.g., T low1 ), the startup is stopped. With this configuration, if the temperature of the precision equipment is lower than the guaranteed operating temperature by a certain amount or more, the startup operation can be stopped without performing the heating operation. This makes it possible to stop the startup if it takes time to start even after performing the heating operation or if the temperature state is not appropriate for startup.

[0044] Furthermore, in the precision device according to this embodiment, the control unit stops the start-up if the temperature inside the precision device does not fall within a predetermined range after a predetermined time has elapsed since the cooling mechanism and the heating mechanism were activated. With this configuration, it is possible to stop the start-up operation if it is determined that the temperature of the precision device cannot be adjusted to the guaranteed operating temperature by the cooling operation or the heating operation. This makes it possible to stop the start-up if it takes time to start up even after the heating operation has been performed, or if the temperature state is not appropriate for start-up.

[0045] In the precision device according to the present embodiment, the temperature sensor acquires the temperatures of multiple locations within the precision device, and at least one of an upper temperature limit and a lower temperature limit is set for each of the multiple locations. This configuration makes it possible to perform determinations and startup control to adjust the temperatures of multiple locations or parts within the precision device to the guaranteed operating temperature.

[0046] Furthermore, a projector (e.g., 100) according to this embodiment includes a temperature sensor (e.g., 103), a cooling mechanism for cooling the inside of the projector, a light source unit (e.g., 105), and a control unit (e.g., 101) for controlling the operation of the projector, and when the control unit receives an instruction to start the projector, the temperature sensor acquires the temperature inside the projector, and activates the cooling mechanism and the light source unit to control the temperature to be within a predetermined range, and then starts the projector. With this configuration, it is possible to realize more appropriate start-up control by taking into account the usage environment and operating temperature conditions of the projector.

[0047] In the projector according to the present embodiment, the cooling mechanism includes at least one of a fan and a cooling pump. This configuration makes it possible to use a configuration using a fan and a cooling pump to adjust the temperature of the projector.

[0048] In the projector according to the present embodiment, the temperature sensor measures the temperature around the optical system or the light source unit within the projector. This configuration makes it possible to determine whether to perform startup control based on the temperatures around the optical system and the light source unit, which are expected to be significantly affected by temperature changes.
