Example 1

Referring to fig. 1, fig. 1 is a system frame diagram of an environmental safety alarm system suitable for a VPSA oxygen plant according to an embodiment of the present utility model. As shown in fig. 1, the embodiment of the utility model provides an environment safety alarm system suitable for a VPSA oxygen plant, which is applied to a pressure swing adsorption oxygen plant and comprises a safety controller, and an oxygen acquisition device, a dangerous gas acquisition device, a multifunctional alarm device and an image acquisition device which are respectively in communication connection with the safety controller; the safety controller is used for receiving the oxygen information acquired by the oxygen acquisition device, the dangerous gas information acquired by the dangerous gas acquisition device and the image information acquired by the image acquisition device and controlling the multifunctional alarm device to be in a corresponding alarm mode; the alarm mode comprises at least one of an audible and visual alarm mode, a voice prompt mode and a light alarm mode, and is suitable for an environment safety alarm system of a VPSA oxygen production workshop.

Specifically, the VPSA oxygen plant refers to an operation place or a working area where VPSA oxygen plants are used, and each plant required by an oxygen production process, a power supply, a water source, an exhaust system and the like for ensuring the normal operation of each plant, and emergency safety equipment such as fire alarms, fire-fighting equipment, emergency lighting and the like are generally arranged in the plant. The oxygen acquisition device can be an environmental oxygen analyzer, the dangerous gas acquisition device can be a flammable and toxic gas analyzer, and the oxygen acquisition device and the dangerous gas analyzer are respectively in communication connection with an input port of the safety controller and are used for detecting oxygen information and dangerous gas information in a workshop in real time and transmitting data to the safety controller. The oxygen collection device, the hazardous gas collection device may be located in areas of the plant where gas leakage or accumulation may occur, such as near oxygen plants, in poorly ventilated corners, etc. For example, the oxygen collection device may be disposed on a floor or a wall in the workshop, and the hazardous gas collection device may be disposed in an area where hazardous gas leakage in pipes, equipment, storage areas, etc. in the workshop can be sensed at a first time.

It is understood that the oxygen information may be an oxygen concentration and the hazardous gas information may be a flammable gas concentration and/or a toxic gas concentration. The combustible toxic gases produced in the VPSA oxygen plant can be carbon dioxide, hydrogen sulfide, methane and the like. In some VPSA oxygen plants, oxygen can be produced from air, or from gases other than air that can be recovered from energy sources, such as water gas, coke oven gas, converter gas, natural gas, and the like. Typically, these gases contain hazardous gases such as carbon dioxide, hydrogen sulfide, methane, and the like.

The image acquisition device may be a camera connected to a video input port of the safety controller for transmitting real-time pictures in the plant and personnel access pictures at the gate of the plant to the safety controller. In some embodiments, the image capture device comprises at least two, at least a portion of the image capture device is configured to fit into a doorway of the pressure swing adsorption oxygen plant and the remaining portion of the image capture device is configured to fit into a different area within the pressure swing adsorption oxygen plant. In this solution, a camera installed in the workshop may be used to determine abnormal situations in the workshop, such as fire, personnel attendance, etc., wherein the camera may be a panoramic camera, and may be disposed in the workshop at a location capable of covering the entire area, such as a corner, a height, etc.

The multifunctional alarm can be connected to an output port of the safety controller through a signal line to receive a trigger signal and is in different alarm modes according to the trigger signal. The safety controller can receive signals from the oxygen acquisition device and the dangerous gas acquisition device and output corresponding control signals to the multifunctional alarm device according to a preset safety strategy. Specifically, when the safety controller judges the abnormal situation, the safety controller is in an audible and visual alarm mode or a light alarm mode to send out an audible and/or light alarm signal, so that the safety controller is beneficial to immediately taking emergency measures to ensure safety. When the safety controller judges the normal condition, the camera monitors personnel to enter and exit the workshop entrance simultaneously, and the safety controller is in a voice prompt mode, so that personnel in the entering and exiting workshop can be helped to know the safety condition of the workshop. By way of example, the multi-function alarm may be located at a location within the plant that is easily visible and audible to personnel, such as a doorway, wall, ceiling, etc.

It should be explained that the safety controller is understood as a module for monitoring and managing the safety system of the workshop, which serves as a central control unit for accessing the devices such as the oxygen acquisition device, the hazardous gas acquisition device, the multifunctional alarm device, the image acquisition device, etc. The safety controller can process and analyze each piece of information and compare the information with a preset threshold value to judge whether the workshop is in a normal condition or not. The safety controller can judge whether abnormal conditions exist in the workshop or not according to input signals of various devices, such as too low or too high oxygen concentration, toxic gas leakage or accumulation, fire or explosion and the like, and output corresponding control signals according to a preset safety strategy to control the multifunctional alarm device to be in a corresponding alarm mode. For example, when the safety controller receives the oxygen information and compares the oxygen information with the preset safety oxygen concentration, if the oxygen concentration is too low or too high, the workshop is judged to be in an abnormal condition, otherwise, the workshop is judged to be in a normal condition.

It can be understood that the predetermined threshold value according to which the oxygen information and the dangerous gas information judged by the safety controller are different is generally smaller than the predetermined threshold value of the oxygen information, so that the multifunctional alarm device can be controlled to be in the audible and visual alarm mode or the light alarm mode when the dangerous gas leaks.

It is worth mentioning that the oxygen acquisition device, the dangerous gas acquisition device, the image acquisition device and the multifunctional alarm can communicate with the safety controller through serial ports through communication cables.

Thus, the environment safety alarm system suitable for the VPSA oxygen production workshop can control the multifunctional alarm to start different alarm modes according to the safety state of the workshop. The safety controller receives the gas information acquired by the oxygen acquisition device and the dangerous gas acquisition device in the workshop in real time and judges whether the workshop is in a normal condition or not. When the alarm device is in a normal condition, personnel access conditions can be monitored in real time according to cameras arranged at the workshop gate, and the multifunctional alarm device is controlled to be in a voice prompt mode to prompt safety. Thereby the operating time and the frequency of the multifunctional alarm device are reasonably controlled, the electric power resource is saved, the influence on the environment is reduced, the voice broadcasting frequency and the power consumption of the multifunctional alarm device are reduced, the service life and the maintenance period of the multifunctional alarm device are prolonged, the noise pollution of a workshop is reduced, unnecessary voice playing when no person enters is avoided, and the interference and the influence on normal staff in the workshop are reduced.

It can be understood that when the abnormal situation in the workshop is judged, the personnel access situation collected by the camera arranged at the workshop gate can be directly entered into the audible and visual alarm mode and the light warning mode without being combined, and the personnel is reminded to take countermeasures. Meanwhile, the camera arranged in the workshop can be combined, so that operators can know the corresponding area under the condition that the fire possibly occurs.

In some embodiments, the multi-functional alarm device is a multi-functional audible and visual alarm; the multifunctional audible and visual alarm is used for receiving the control information transmitted by the safety controller and sending out corresponding audible and visual alarm, voice prompt or light warning. In this embodiment, the multi-functional audible and visual alarm integrates three modes, that is, can send out audible and visual alarm of sound and light simultaneously, or send out light warning only, or carry out voice broadcast only. When the oxygen concentration is detected to be too low or too high and the concentration of the combustible gas or the toxic gas exceeds the explosion limit or the hazard limit, the safety controller can send out control information carrying an alarm instruction to control the multifunctional audible and visual alarm to send out audible and visual alarm or light warning. When the safety controller is in normal condition, the safety controller can send out control information carrying with voice prompt instruction to control the multifunctional audible and visual alarm to send out voice prompt.

For example, when in a normal condition, the multi-function audible and visual alarm may play pre-recorded safety prompts such as "shop safety, please keep vigilance" or other appropriate prompts to alert personnel to maintain a safe state. In a dangerous state, the voice alarm system can trigger warning voice and activate light at the same time. For example, if a hazardous gas leak or other emergency condition is detected, the system may automatically play a voice alert, such as "danger-! Please immediately evacuate the shop-! And simultaneously flashing the light to increase the warning effect.

In the embodiment, the multifunctional audible and visual alarm can be a commercially available YD-D3 series wireless remote control audible and visual alarm, the series products support three mode switching, and the voice content can be replaced through a USB port.

In still other embodiments, the multi-functional alarm device comprises a general purpose audible and visual alarm and a voice broadcast; the general audible and visual alarm is used for receiving the first control information transmitted by the safety controller and sending out audible and visual alarm or light warning; and the voice broadcasting device is used for receiving the second control information transmitted by the safety controller and broadcasting voice prompts. In this embodiment, the multifunctional audible and visual alarm may be a general audible and visual alarm and a voice broadcasting device that are used in cooperation, that is to say, the general audible and visual alarm may be responsible for sounding and light audible and visual alarm, or only send light warning, and the voice broadcasting device may be responsible for voice broadcasting. When the oxygen concentration is detected to be too low or too high, and the concentration of the combustible gas or the toxic gas exceeds the explosion limit or the hazard limit, the safety controller can send out first control information carrying an alarm instruction to control the general audible and visual alarm to send out audible and visual alarm or light warning. When the safety controller is in a normal condition, the safety controller can send out second control information carrying with a voice prompt instruction to control the voice broadcasting device to send out a voice prompt.

For example, when in a normal condition, the voice broadcaster may play pre-recorded safety prompts, such as "workshop safety, please keep vigilance" or other appropriate prompts, to alert the staff to maintain a safe state. Under dangerous state, the general audible and visual alarm can trigger warning voice and activate light at the same time. For example, if a hazardous gas leak or other emergency condition is detected, the system may automatically play a voice alert, such as "danger-! Please immediately evacuate the shop-! And simultaneously flashing the light to increase the warning effect.

It can be understood that the general audible and visual alarm has wide sources and low price, and can save the input cost of the system.

Still further, the voice prompt mode includes a safety prompt mode and/or a parameter prompt mode, the safety prompt mode is used for broadcasting safety states in the workshop, and the parameter prompt mode is used for broadcasting gas parameters in the workshop. In this embodiment, when the workshop is in normal condition, multi-functional alarm device not only can play safe suggestion pronunciation, can also implement to report information such as safety inspection numerical value according to the gas concentration that oxygen acquisition device, dangerous gas acquisition device gathered, and the personnel are convenient for know the degree of safety of workshop environment when getting into and leaving the workshop, improve VPSA oxygen production workshop safety automation level, effectively make the safety precaution.
