The actuator 3 includes a temperature adjusting device, a humidity adjusting device, or a pressure adjusting device. For example, in the case where the environmental parameter is temperature, the first protection action that the control device 2 controls the execution device 3 (temperature adjustment device) to execute may be a temperature lowering action or a temperature raising action. For the case where the environmental parameter is humidity, the first protection action that the control device 2 controls the execution device 3 (humidity adjustment device) to execute may be a dehumidification action or a humidification action. For the case where the environmental parameter is pressure, the first protection action that the control device 2 controls the execution device 3 (pressure adjustment device) to execute may be a pressure-decreasing action or a pressure-increasing action.

In the embodiment of the present invention, for the situation where the first protection action requires additional power, the power device 4 is additionally provided between the control device 2 and the executing device 3.

The embodiment of the utility model provides an in, controlling means 2's the control unit includes central processing unit to based on the actual environment parameter signal that detection device 1 sent and preset predetermine the environmental parameter scope, confirm whether actual environment parameter surpasss and predetermine the environmental parameter scope. For example, in the embodiment of the present invention, the control unit of the control device 2 is configured to control the execution device 3 to perform the first protection action, or to perform the second protection action on the sealed test apparatus 100 (for example, the control device 2 is connected to the power supply of the sealed test apparatus 100 and controls the power supply of the sealed test apparatus 100 to be powered off).

In the embodiment of the present invention, the control device 2 may be an Energy Management System (EMS), which is a general term for a modern power grid dispatching automation System (including hardware and software). The main function of the system is composed of a basic function and an application function. The basic functions include: a computer, an operating system, and an EMS support system.

Based on whether the actual environmental parameter inside the sealed test apparatus 100 is within the preset environmental parameter range, for example, the actual environmental parameter is out of the preset environmental parameter range or the actual environmental parameter falls within the preset environmental parameter range, the control device 2 controls the execution or non-execution of the first protection action and the second protection action accordingly.

For example, when the actual environmental parameter exceeds the preset environmental parameter range, the control device 2 may perform a second protection action on the sealed test apparatus 100, i.e. control the sealed test apparatus 100 to be powered off. At this time, the control device 2 may also control the power device 4 to start and drive the actuator 3 to perform the first protection action. Therefore, the safety of the test product and the reliability of the test data are ensured, and possible safety accidents are avoided. After the first protection action is executed for a period of time, when the detected actual environmental parameter inside the sealed test apparatus 100 falls within the preset environmental parameter range, the control device 2 controls the power device 4 to be turned off, thereby stopping driving the execution device 3 to execute the first protection action. At this time, the control device 2 may control to resume the power supply to the sealed test apparatus 100, thereby ensuring the normal operation of the sealed test apparatus 100 and the safety of the internal devices thereof.

The following description will be given of a specific configuration and operation of the closed type test apparatus 100, taking the example where it is a constant temperature closed type test apparatus.

The constant temperature and closed type test equipment can be constant high temperature and closed type test equipment or constant low temperature and closed type test equipment. The detection means 1 comprise a temperature sensor and the actuation means 3 comprise a temperature regulation means. Specifically, the temperature sensor detects the actual temperature inside the constant-temperature closed-type test apparatus, and sends an actual temperature signal to the control device 2.

The control device 2 receives the actual temperature signal sent by the detection device 1 and compares the actual temperature corresponding to the actual temperature signal with a preset temperature range. In the constant high temperature hermetic type test apparatus, when the actual temperature is higher than the upper limit of the preset temperature range, the control device 2 may control the temperature adjusting device to perform the first protection action. Here, the first protection action is to perform a cooling protection action on the constant high temperature sealed test apparatus to lower an actual temperature inside the constant high temperature sealed test apparatus to fall within a preset temperature range. Meanwhile, the control device 2 performs a second protection action (power off) on the constant high temperature closed type test equipment, thereby realizing a protection effect on the constant high temperature closed type test equipment. The embodiment of the utility model provides an in, temperature regulation apparatus is the heat sink, and the heat sink can be air-blower, compressor, fan etc..

In the constant low temperature closed type test apparatus, the control device 2 may control the temperature adjusting device to perform the first protection action when the actual temperature is lower than the lower limit of the preset temperature range. Here, the first protection action means performing a temperature rise protection action on the thermostatic and cryogenic sealed type test apparatus to raise an actual temperature inside the thermostatic and cryogenic sealed type test apparatus to fall within a preset temperature range. Meanwhile, the control device 2 executes power-off protection action on the constant low-temperature closed type test equipment, so that the protection effect on the constant low-temperature closed type test equipment is further realized. The embodiment of the utility model provides an in, temperature regulation apparatus is rising temperature device, and rising temperature device can be electric heater unit, for example the heating rod.

In some embodiments, the temperature adjustment device may include both a temperature reduction device and a temperature increase device.

In the embodiment of the present invention, the constant temperature closed test equipment is only the embodiment of the present invention is an embodiment, and the closed test equipment with constant parameters can also be constant humidity closed test equipment, constant pressure closed test equipment, etc. Accordingly, in the constant-humidity closed-type test apparatus, the detecting device 1 includes a humidity sensor, and the actuating device 3 includes a humidity adjusting device. In the constant-pressure closed-type test apparatus, the detecting means 1 includes a pressure sensor, and the executing means 3 includes a pressure adjusting means. It will be further appreciated that the constant parameter hermetic test apparatus in embodiments of the present invention may also be one or more of the above-described hermetic test apparatuses. For example, in the embodiment of the present invention, the constant parameter closed type testing apparatus may be a constant temperature and constant pressure closed type testing apparatus, and accordingly, in the constant temperature and constant pressure closed type testing apparatus, the detecting device 1 includes a temperature sensor and a pressure sensor. The actuator 3 includes a temperature adjusting device and a pressure adjusting device. The detailed description thereof is omitted here.

The following describes the closed test apparatus according to an embodiment of the present invention with reference to fig. 2 to 5, taking the closed test apparatus as a constant high temperature closed test apparatus and an apparatus self-protection device for preventing the actual temperature inside the closed test apparatus from exceeding the upper limit of the preset temperature range as an example.

Fig. 2 is a schematic block diagram illustrating an apparatus self-protection device of a hermetic test apparatus according to another exemplary embodiment of the present invention.

Specifically, as shown in fig. 2, the closed test apparatus 100 in the embodiment of the present invention may be a constant high temperature closed test apparatus, and the temperature sensor 11 of the apparatus self-protection device 101 inside the closed test apparatus may be a wireless temperature sensor, and the wireless temperature sensor is connected to the control device 2 in a wireless connection manner. The temperature sensor 11 may be electrically connected to the control device 2 by a wire. The actuator 3 may be a cooling device 31 in a thermostat. The temperature sensor 11 detects the actual temperature inside the thermostatic high-temperature sealed test apparatus and sends an actual temperature signal to the control device 2.

The control device 2 compares the actual temperature with a preset temperature range. When the actual temperature exceeds the upper limit of the preset temperature range, the control device 2 executes power-off protection action on the constant high-temperature closed type test equipment. And the control device 2 can control the power device 4 to start and drive the cooling device 31 to perform cooling protection action on the constant high temperature closed type test equipment.

Further, in the embodiment of the present invention, the cooling device 31 may be a compressor, an air blower, a fan, or any device capable of cooling the constant high temperature closed test equipment. However, when the cooling device 31 is started and cools the constant high temperature sealed test equipment, so that the actual temperature inside the constant high temperature sealed test equipment falls within the preset temperature range, the control device 2 may control to turn off the power device 4, and then stop driving the cooling device 31 to perform the first protection action. At this time, the control device 2 can control the power supply of the constant high temperature closed type test equipment to be recovered, and the constant high temperature closed type test equipment is restarted to continue working.

The embodiment of the present invention provides an apparatus self-protection device for a closed test apparatus 100, which can improve the automation protection of the closed test apparatus 100, and ensure that the actual temperature inside the closed test apparatus 100 falls into the preset temperature range. The reliability of test data of a test product and the safety of the sealed test apparatus 100 are ensured while the normal operation of the sealed test apparatus 100 is ensured. In addition, occurrence of unsafe events due to malfunction or human factors of the hermetic test apparatus 100 can be prevented.

Further, in order to prevent the device self-protection device from being triggered by mistake, the number of the temperature sensors 11 is relatively increased in the embodiment of the present invention. Fig. 3 is a schematic block diagram illustrating an apparatus self-protection device of a hermetic test apparatus according to another exemplary embodiment of the present invention. The differences from the embodiment shown in fig. 2 include that the number of temperature sensors 11 is increased while adding the time relay 5.

Specifically, as shown in fig. 3, in the closed type test apparatus 200 according to the embodiment of the present invention, a constant high temperature closed type test apparatus is taken as an example for explanation, and the detection device 1 of the apparatus self-protection device 201 therein includes two temperature sensors 11. The two temperature sensors 11 are disposed apart, and detect the actual temperature inside the hermetic type test apparatus 200, and send an actual temperature signal to the control device 2. For example, when the control device 2 determines that the actual temperatures detected by the two temperature sensors 11 both exceed the upper limit of the preset temperature range, the power-off protection operation is performed on the closed test apparatus 200. In addition, the control device 2 may control the power device 4 to start and drive the cooling device 31 to perform a cooling protection action on the sealed test apparatus 200, so that the actual temperature inside the sealed test apparatus 200 is reduced to fall within a preset temperature range through the cooling protection action of the cooling device 31, thereby implementing a protection action on the sealed test apparatus 200.

In this embodiment, since the two temperature sensors 11 are included in the device self-protection apparatus 201, and the cooling protection operation is performed only when the two temperature sensors 11 detect that the actual temperatures inside the sealed test device 200 both exceed the upper limit of the preset temperature range, the purpose of double protection is achieved, and the protection operation is prevented from being performed by mistake due to a detection error of the temperature sensors 11.

For the case that the actual temperature inside the sealed test apparatus is lower than the lower limit of the preset temperature range, the specific process is similar to the above-mentioned cooling protection process except that the actual temperature inside the sealed test apparatus 200 is raised to fall within the preset temperature range by the heating protection action of the heating device in the temperature adjustment device, and is not described herein again. Compared with the embodiment shown in fig. 2, the embodiment shown in fig. 3 is additionally provided with a time relay 5. The control device 2 instructs the time relay 5 to start timing when it is determined that the actual temperatures detected by the two temperature sensors 11 each exceed the upper limit of the preset temperature range. For example, when the time during which the actual temperatures each exceed the upper limit of the preset temperature range reaches a preset time length, for example, 3 minutes, the control device 2 performs the power-off protection operation on the hermetic test apparatus 200 based on the timing data transmitted from the time relay 5. Furthermore, the control device 2 controls the power device 4 to start, and the power device 4 drives the cooling device 31 to perform a cooling protection action on the sealed test apparatus 200.

Further, after the temperature lowering protection operation is started, the temperature sensor 11 continues to detect the actual temperature inside the sealed test apparatus 200. When the actual temperature detected by the temperature sensor 11 falls within the preset temperature range, for example, below 25 ℃, the control device 2 controls the time relay 5 to time the state where the actual temperature falls within the preset temperature range. When the time that the actual temperature is reduced to be within the preset temperature range reaches a preset time length, for example, 10 minutes, the control device 2 controls the power device 4 to be turned off and stops driving the cooling device 31 to perform a cooling protection action on the constant high temperature closed type test equipment. At this point, the power supply to the sealed test apparatus 200 may be resumed to continue its operation.

It should be further understood that the number of the temperature sensors 11 disposed in the apparatus self-protection device 201 of the closed test apparatus 200 according to the embodiment of the present invention is not limited thereto, and may be two or more. For example, if the sealed space of the sealed test apparatus 200 of the embodiment of the present invention is relatively large, the number of the temperature sensors 11 of the apparatus self-protection device 201 of the sealed test apparatus 200 can be correspondingly increased to meet the requirement of accurately judging the actual temperature inside the sealed test apparatus.

Fig. 4 is a schematic block diagram illustrating an apparatus self-protection device of a closed test apparatus according to another exemplary embodiment of the present invention.

To serve the purpose of alerting the event status, the present invention provides yet another embodiment. The difference between the embodiment shown in fig. 4 and the embodiment of fig. 3 includes that an alarm device for event reminding is added in the present embodiment. Specifically, the closed test apparatus 300 in the embodiment of the present invention is exemplified by a constant high temperature closed test apparatus. The equipment self-protection device 301 inside it also comprises an alarm device 6 capable of emitting sound, light or electric signals. For example, the alarm device 6 may include a warning light or an alarm bell, and may include only one of the warning light and the alarm bell, or may be used in combination of both, as long as the purpose of reminding the event state is achieved.

In the embodiment of the present invention, the alarm device 6 is electrically connected to the control device 2 in a wired manner. When the actual temperature exceeds the upper limit of the preset temperature range, the alarm device 6 gives an alarm to remind the staff of the occurrence of event states such as failure of the closed type testing equipment 300, so as to remind the relevant staff of timely handling the failure of the closed type testing equipment 300, and avoid the occurrence of safety accidents.

Further, a warning light may be added to the device self-protection device 301 inside the closed test apparatus 300, and when the actual temperature falls within the preset temperature range, the control device 2 controls the warning light to light up to remind the worker that the actual temperature inside the closed test apparatus 300 falls within the preset temperature range. At this time, the hermetic test apparatus 300 may be restarted.

The embodiment of the utility model provides an in, also can add the warning light alone on the inside equipment self-protection device 301 of closed test equipment 300, the actual temperature signal that controlling means 2 received temperature sensor 11 in real time and sent to whether exceed the upper limit of predetermineeing the temperature range according to actual temperature, control the warning light and send the light of different colours, in order to remind different incident states.

Further, in the embodiment of the present invention, a display screen (not shown) may be additionally disposed on the equipment self-protection device 301 of the constant high temperature sealed test equipment, and the display screen is electrically connected to the control device 2 in a wired manner, and may also be connected in a wireless manner. The fault information of the sealed test equipment 300 can be displayed on the display screen through the display screen, so that the safety state of the sealed test equipment 300 is more intuitive. The control device 2 may also transmit failure information of the sealed test apparatus 300 to a communication device of a worker, such as a mobile phone. The embodiment of the utility model provides an in, can save staff's time, and needn't need the staff on-the-spot guard of squatting.

Specifically, fig. 5 is a schematic block diagram illustrating an apparatus self-protection apparatus of a closed test apparatus according to an exemplary embodiment of the present invention.

As shown in fig. 5, the closed test apparatus 300 in the embodiment of the present invention is described by taking a constant high temperature closed test apparatus as an example. The equipment self-protection device 301 therein includes two temperature sensors 11 as detection devices, a time relay 5, a control device 2, an alarm device 6, a first motor 41 as a power device, and a compressor 311. In the embodiment of the present invention, the compressor 311 is a temperature adjusting device, which is a cooling device, as an actuating device. Different cooling devices can be loaded according to different application environments or different application equipment. For example, when there is no requirement for the external environment of the use place, the apparatus self-protection device 301 in the sealed test apparatus 300 according to the embodiment of the present invention may be equipped with a cooling device such as a fan to cool the sealed test apparatus 300. When the environment of the use place has a precise requirement, the compressor 311 can be loaded to independently cool the closed test equipment 300, so as to prevent the exhausted hot air or moisture from influencing other environments.

In the embodiment of the present invention, the device self-protection device 301 in the closed test apparatus 300 can be applied to different environmental situations, and is not limited to different applications.

The closed test equipment 300 in this embodiment is a constant high temperature closed test equipment, and can be used for testing and determining parameters and performance of electricians, electronics, other products and materials after temperature environment changes for high temperature or constant tests.

When the constant high temperature closed type test equipment starts to work, a heating device such as a heater in the constant high temperature closed type test equipment starts to heat. The two temperature sensors 11 detect the actual temperature in the constant high temperature closed type testing device, when the actual temperature detected by the two temperature sensors 11 both exceed the upper limit of the preset temperature range, the control device 2 controls the first motor 41 to start, and the first motor 41 drives the compressor 311 to perform cooling protection action on the constant high temperature closed type testing device. Meanwhile, the control device 2 executes power-off protection action on the constant high-temperature closed type test equipment, and then the power supply of the heating device is cut off, so that the heating device stops working.

When the actual temperatures detected by the two temperature sensors 11 both exceed the upper limit of the preset temperature range, the control device 2 controls the time relay 5 to time the state that the actual temperature sent by the temperature sensors 11 exceeds the upper limit of the preset temperature range, and the time relay 5 sends the timing data to the control device 2. When the time during which the actual temperature exceeds the upper limit of the preset temperature range reaches a preset time length, for example, 3 minutes, the control device 2 controls the first motor 41 to be started. The control device 2 performs a power-off protection operation on the constant-temperature closed test equipment.

When the first protection action is performed, the first motor 41 is started and drives the compressor 311 to perform a cooling protection action on the constant high temperature sealed test equipment. When the temperature sensor 11 detects that the temperature after the temperature reduction falls within the preset temperature range, the control device 2 controls the time relay 5 to start timing. The time relay 5 transmits the timing data to the control device 2. When the actual temperature detected by the temperature sensor 11 falls within the preset temperature range for a preset time period, for example, 10 minutes, the control device 2 controls the first motor 41 to stop operating. When the first motor 41 stops operating, the compressor 311 stops cooling the thermostatic closed test apparatus.
