Detailed Description
In order to make the technical scheme and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
In the embodiment of the invention, environment monitoring elements such as temperature and humidity sensors capable of automatically recording environment information are respectively arranged in the CT equipment and the carriage of the vehicle-mounted CT system. When the environmental parameters exceed the standard, the environmental parameters are informed to users or drivers in the form of alarm, and meanwhile, the environmental information is sent to the service center at regular time through communication equipment such as a wireless network card (for example, 4G or 5G).
Fig. 1 is a flowchart of an environment monitoring method of a vehicle-mounted CT apparatus according to an embodiment of the present invention, which may be implemented by a control host in the vehicle-mounted CT apparatus.
As shown in fig. 1, the method includes:
step 101: and collecting internal environment parameters of the vehicle-mounted CT equipment.
Among them, the on-vehicle CT apparatus generally includes: (1) the scanning part comprises an X-ray tube, a detector and a scanning frame; (2) the control host part is used for storing and operating the information data collected by scanning; (3) and the image display and storage system is used for displaying the image processed and reconstructed by the control host part on a display screen.
Through various sensors arranged on the vehicle-mounted CT device, the control host can acquire internal environment parameters of the vehicle-mounted CT device. For example, the control host can acquire the temperature value in the shell through a temperature sensor arranged in the shell of the X-ray tube; the control host can acquire the temperature value in the detector through a temperature sensor arranged in the detector; the control host can acquire the vibration intensity of the vehicle-mounted CT equipment through a vibration sensor arranged on the vehicle-mounted CT equipment, and the like.
Step 102: and collecting compartment environmental parameters of a compartment space for accommodating the vehicle-mounted CT equipment.
In one embodiment, the cabin environmental parameter comprises at least one of: a car temperature value; a compartment humidity value; car geographical location, etc.
For example, the control host may collect a vehicle temperature value based on a temperature sensor disposed in the cabin space, a vehicle humidity value based on a humidity sensor disposed in the cabin space, geographic location information (e.g., GPS coordinates) of the vehicle based on a location sensor disposed in the cabin space, and so forth.
Step 103: when it is determined that the internal environmental parameter and/or the cabin environmental parameter are abnormal, an environmental alarm prompt is displayed, and an abnormal alarm message including the internal environmental parameter and/or the cabin environmental parameter is transmitted to a server disposed remotely.
When the control host compares the internal environment parameters with the preset internal environment parameter threshold value and finds that the internal environment is abnormal, an alarm prompt for prompting the internal environment to be abnormal is displayed on a display interface of the control host.
For example, when the control host finds that the internal temperature value of the X-ray tube is greater than the predetermined internal temperature threshold value of the X-ray tube, an alarm prompt for prompting that the internal temperature of the X-ray tube is too high is displayed on a display interface of the control host.
And when the control host compares the compartment environment parameters with the preset compartment environment parameter threshold value and finds that the compartment environment is abnormal, displaying an alarm prompt for prompting the abnormality of the compartment environment parameters on a display interface of the control host.
For example, when the control host finds that the temperature value of the car is greater than the preset car temperature threshold value, an alarm prompt for prompting that the temperature of the car is too high is displayed on a display interface of the control host.
In addition, when the cabin environmental parameter is abnormal or the internal environment is abnormal, the control host transmits an abnormality warning message containing the internal environmental parameter and/or the cabin environmental parameter to a server disposed at a remote place.
For example, the control host sends the anomaly alert message to a remotely disposed server via a wireless interface, wherein the wireless interface includes at least one of: infrared interface, near field communication interface, bluetooth interface, zigbee interface, wireless broadband interface, and the like. Preferably, the wireless interface may be implemented as a 4G interface or a 5G interface. After receiving the abnormal alarm message, the server may determine a corresponding device operation instruction based on the fault object specified in the abnormal alarm message, and send the device operation instruction to the control host. The control host may receive device operation instructions from the server that are determined based on the exception alert message. The control host controls and executes the equipment operation instruction, carries the operation result in a response message, and sends the response message to the server. Wherein the equipment operation instruction is used for instructing to eliminate the internal environment parameter abnormity and/or the compartment environment parameter abnormity. For example, when the internal environmental parameter abnormality shows that the internal temperature of the X-ray tube is too high, the device operation command is used to command a cooling element (such as a fan or a water cooling element) in the X-ray tube to perform a cooling operation, and the operation result is a result of the cooling operation (such as the temperature of the cooled X-ray tube).
In one embodiment, the on-board CT device includes an X-ray tube, the internal environmental parameter is a temperature value within a housing of the X-ray tube, and the cabin environmental parameter is a cabin temperature value; the method further comprises the following steps: when the temperature value of the carriage is judged to be normal and the temperature value in the shell is judged to be abnormal, generating an instruction for adjusting the temperature value in the X-ray tube; when the temperature value of the carriage is judged to be abnormal and the temperature value in the shell is normal, generating a command for adjusting the temperature value of the carriage; when the temperature value in the shell is judged to be abnormal and the temperature value in the shell is abnormal, generating a command for adjusting the temperature value in the X-ray tube and a command for adjusting the temperature value of the carriage, wherein when the temperature value in the shell is the same as the abnormal state of the temperature value of the carriage, the command for adjusting the temperature value of the carriage is adapted to the abnormal state of quickly reducing the temperature value of the carriage. Wherein: the abnormal state of the temperature value in the shell and the temperature value of the carriage has the same meaning as that of the following condition: the temperature value in the shell is greater than a preset high-temperature threshold value in the shell, and the temperature value of the carriage is greater than a preset high-temperature threshold value of the carriage; or the temperature value in the shell is smaller than a preset shell internal low-temperature threshold value and the carriage temperature value is smaller than a preset carriage low-temperature threshold value. Also, the meaning of the abnormal state adapted to rapidly lower the temperature value of the vehicle cabin is: compared with the abnormal temperature value of the carriage, when the temperature value in the shell is normal, the abnormal state of the temperature value of the carriage is reduced more quickly.
In one embodiment, the vehicle-mounted CT device includes a detector, the internal environment parameter is a temperature value in the detector, and the compartment environment parameter is a compartment temperature value; the method further comprises the following steps: when the temperature value of the compartment is judged to be normal and the temperature value in the detector is abnormal, generating an instruction for adjusting the temperature value in the detector; when the temperature value of the carriage is judged to be abnormal and the temperature value in the detector is normal, generating a command for adjusting the temperature value of the carriage; when the temperature value in the detector is judged to be abnormal and the temperature value in the detector is abnormal, generating a command for adjusting the temperature value in the detector and a command for adjusting the temperature value of the car, wherein when the temperature value in the detector is the same as the abnormal state of the temperature value of the car, the command for adjusting the temperature value of the car is adapted to the abnormal state of rapidly reducing the temperature value of the car. Wherein: the abnormal states of the temperature value in the detector and the temperature value of the car have the same meaning: the temperature value in the detector is greater than a preset high-temperature threshold value in the detector, and the temperature value of the carriage is greater than a preset high-temperature threshold value of the carriage; or the temperature value in the detector is smaller than the preset low-temperature threshold value in the detector and the temperature value of the carriage is smaller than the preset low-temperature threshold value of the carriage. Also, the meaning of the abnormal state adapted to rapidly lower the temperature value of the vehicle cabin is: compared with the abnormal temperature value of the carriage, when the temperature value in the detector is normal, the abnormal state of the temperature value of the carriage is reduced more quickly.
In one embodiment, the method further comprises: acquiring the vibration intensity of the vehicle-mounted CT equipment based on a vibration sensor arranged on the vehicle-mounted CT equipment; when the vibration intensity exceeds a predetermined threshold value, a vibration alarm prompt is generated, and a vehicle control instruction for reducing the vibration intensity is generated. For example, the vehicle control command may be a parking command or a deceleration command.
The above exemplary description is directed to the monitoring manner of each component of the on-board CT apparatus, and those skilled in the art will recognize that this description is only exemplary and is not intended to limit the scope of the embodiments of the present invention.
Fig. 2 is a schematic diagram of a vehicle-mounted CT apparatus according to an embodiment of the present invention.
As seen in fig. 2, the on-board CT system 10 includes a transport vehicle 11, a cabin 12, and an on-board CT device disposed in the cabin 12. Specifically, the on-vehicle CT apparatus includes an examination couch 13, a gantry 14, a detector 15 and an X-ray tube 18 arranged in the gantry 14, a control host computer 16, and a wireless interface 17. The scanning frame 14 and the examination table 13 are connected to the carriage 12 through support frames, respectively.
Contained within the control host 16 is a memory and a processor, wherein the processor is configured for: collecting internal environment parameters of the vehicle-mounted CT equipment; collecting compartment environmental parameters of a compartment space containing vehicle-mounted CT equipment; when it is determined that the internal environmental parameter and/or the cabin environmental parameter are/is abnormal, an environmental alarm prompt is displayed, and an abnormal alarm message containing the internal environmental parameter and/or the cabin environmental parameter is/are sent to a server arranged remotely.
The first embodiment is as follows:
a processor in the control host 16 obtains the temperature of the X-ray tube 18 (e.g., the anode temperature) via a temperature sensor (not shown in fig. 2) disposed in the X-ray tube 18 of the gantry 14.
In an alternative embodiment, when the processor finds that the temperature of the X-ray tube 18 is too high (e.g., exceeds the X-ray tube temperature upper limit value), the processor may send an abnormality alarm message containing the temperature value of the X-ray tube 18, which further contains a field for identifying the faulty object (i.e., the X-ray tube 18), to a remotely disposed server via the wireless interface 17. After receiving the abnormality warning message, the server determines that the temperature of the X-ray tube 18 is too high based on this field, and sends an X-ray tube cooling instruction to the wireless interface 17. The processor in the control host 16 receives the X-ray tube cooling command via the wireless interface 17, and cools the X-ray tube 18 based on the X-ray tube cooling command (for example, the control host 16 controls the fan in the X-ray tube to increase the cooling power). In another alternative embodiment, when the processor finds that the temperature of the X-ray tube 18 is too high, an X-ray tube cooling command is generated and controls a cooling element in the X-ray tube 18 to cool the X-ray tube 18.
Also, when the processor finds that the temperature of the X-ray tube 18 is excessively high, an environmental alarm prompt for prompting that the internal temperature of the X-ray tube 18 is excessively high is generated, and the environmental alarm prompt is displayed on the display interface.
Example two:
the processor in the control host 16 acquires the ambient temperature value in the cabin 12 via a temperature sensor 19 disposed in the cabin 12. In an alternative embodiment, when the processor finds that the ambient temperature value in the car 12 is too high (e.g., exceeds the car temperature upper limit value), the processor sends an exception alert message containing the temperature value of the car 12, which further contains a field identifying the faulty object (i.e., the car 12), to a remotely located server via the wireless interface 17. After receiving the abnormal warning message, the server determines that the temperature of the car 12 is too high based on the field, and then sends a car cooling command to the wireless interface 17. The processor in the control host 16 receives the cabin cooling command via the wireless interface 17, and cools the cabin 12 based on the cabin cooling command (e.g., controls the on-board air conditioning system to increase cooling power). In another alternative embodiment, when the processor finds that the ambient temperature in the cabin 12 is too high, the control host generates a cabin cooling command by itself and controls the on-board air conditioning system to cool the cabin 12.
Also, when the processor finds that the ambient temperature value in the cabin 12 is excessively high, the processor generates an ambient alarm prompt for prompting that the ambient temperature of the cabin 12 is excessively high, and displays the ambient alarm prompt on the display interface.
Example three:
the processor in the control host 16 acquires the temperature of the X-ray tube 18 (e.g., the anode temperature) via a temperature sensor disposed in the X-ray tube 18 of the gantry 14, and acquires the ambient temperature value in the cabin 12 via a temperature sensor 19 disposed in the cabin 12. When the processor finds that the temperature of the X-ray tube 18 is too high (e.g., exceeds the X-ray tube temperature upper limit value) and the ambient temperature value in the cabin 12 is too high (e.g., exceeds the cabin temperature upper limit value), it is assumed that the environment of both the X-ray tube 18 and the cabin 12 is abnormal. The processor determines that the abnormal state of the X-ray tube temperature is the same as the abnormal state of the vehicle cabin 12 temperature, and both the abnormal state and the abnormal state are excessive temperatures. The control host generates an instruction for adjusting the temperature value in the detector and an instruction for adjusting the temperature value of the car, wherein the instruction for adjusting the temperature value of the car is adapted to an abnormal state for rapidly reducing the temperature value of the car. For example, the command for adjusting the temperature value of the cabin has a greater cooling power than the case where only the ambient temperature value in the cabin 12 is excessive.
Example four:
the processor in the control host 16 acquires the ambient humidity value in the cabin 12 via a humidity sensor 20 disposed in the cabin 12. When the processor finds that the ambient humidity value in the cabin 12 is too high (e.g., exceeds the cabin humidity upper limit value), it recognizes that the environment of the cabin 12 is abnormal. In an alternative embodiment, the processor sends an exception alert message containing the moisture value of the car 12 via the wireless interface 17 to a remotely located server, the fault alert message further containing a field identifying the faulty object (i.e., the car 12). After receiving the abnormality warning message, the server determines that the humidity of the vehicle cabin 12 is too high based on the field, and sends a vehicle cabin dehumidification command to the wireless interface 17. The processor in the control host 16 receives the cabin dehumidification command via the wireless interface 17 and performs dehumidification for the cabin 12 (e.g., controls the on-board dehumidification system) based on the cabin cooling command. In another alternative embodiment, when the processor finds that the ambient humidity value in the cabin 12 is too high, the processor generates a cabin dehumidification command and controls the on-board air conditioning system to dehumidify the cabin 12.
Example five:
the processor in the control host 16 acquires the value of the vibration intensity of the X-ray tube 18 via a vibration sensor 21 disposed on the envelope surface of the X-ray tube 18. When the processor finds that the vibration intensity value of the X-ray tube 18 is too large (e.g., exceeds the vibration intensity upper limit value), it is determined that the vibration of the X-ray tube 18 is abnormal. In an alternative embodiment, the processor sends an abnormality warning message containing the value of the vibration intensity of the X-ray tube 18 to a remotely disposed server via the wireless interface 17, the malfunction warning message further containing a field for identifying the malfunctioning object (i.e., the X-ray tube 18). When the server receives the abnormality warning message and determines that the vibration of the X-ray tube 18 is too high based on this field, it sends a vehicle stop instruction to the wireless interface 17. The processor in the control host 16 receives the vehicle stop instruction via the wireless interface 17, and stops the vehicle based on the vehicle stop instruction. In another alternative embodiment, when the processor finds that the value of the vibration intensity of the X-ray tube 18 is excessive, the processor generates a vehicle stop instruction and controls the vehicle to stop.
Based on the above description, the embodiment of the invention also provides an environment monitoring device of the vehicle-mounted CT device.
