in the figure: 1-light character plate, 2-main alarm character display area, 3-sub-level alarm terminal, 4-sub-level alarm display screen, 5-equipment access terminal, 6-digital-to-analog conversion module, 7-communication module, 8-DCS system and 8.1-DCS system display module.

Detailed Description

The above-described aspects are further described below in conjunction with specific embodiments. It is to be understood that these examples are illustrative of the utility model and are not intended to limit the scope of the utility model. The implementation conditions used in the examples may be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are generally those in routine experiments.

In a specific embodiment, an optical character board alarm system is provided, which is the same as a traditional optical character board and is characterized by comprising an optical character board body assembly, wherein the optical character board body assembly can specifically comprise a plate-type mounting frame, a plurality of main alarm character display areas 2 are arranged on the plate-type mounting frame, and an equipment access end 5 is arranged, and the access end 5 is connected with detected equipment or devices and used for transmitting and collecting detection signals. In this example, the main alarm text display area 2 is mainly a plastic plate or block with the mark text of the detection device and capable of highlighting, and when the alarm prompt occurs to the device, the prompt lamp arranged in the main alarm text display area 2 emits light to perform the striking prompt. Because the same equipment or local system needs to be subjected to multi-point step-by-step detection during on-site alarm detection, the excessive main alarm character display areas 2 are arranged, larger installation space is occupied, and the viewing is relatively confusing, therefore, in the embodiment, a plurality of sub-level alarm ends 3 are respectively arranged in one side area of each main alarm character display area 2, and referring to fig. 1, the volume of the sub-level alarm ends 3 in the embodiment is far smaller than that of the main alarm character display areas 2, so that the multi-point detection step-by-step detection ends can be ensured to be arranged to a certain extent, the placement space is saved, and in the embodiment, the plurality of sub-level alarm ends 3 are arranged at the bottom position of the main alarm character display areas 2.

In addition, for the function that also can play the warning suggestion, this example neutron level warning end 3 includes the display part, and its inside mainly is provided with the suggestion light, and is the same with main warning word display area 2 theory of operation, and inside light lights when receiving the detected signal and carries out striking suggestion, as the preferred embodiment of this example, in order to avoid the too near light photo interaction that sublevel warning end 3 and main warning word display area 2 were close to, be provided with the baffle between main warning word display area 2 and the sublevel warning end 3. And then can keep apart the two through the baffle between, the staff of being convenient for looks over.

In addition, for the quick view of sub-level alarm information of being convenient for, arrange in light word tablet 1 one side region and be provided with a plurality of sub-level alarm display screen 4, in this example, sub-level alarm display screen 4 installs in light word tablet 1 bottom, wherein, in order to make things convenient for the loading and unloading of a plurality of sub-level alarm display screen 4 according to the system detection needs, sub-level alarm display screen 4 is removable to be pegged graft in one side of light word tablet 1, in this example is pegged graft in light word tablet 1 bottom to a plurality of sub-level alarm display screen 4 are removable grafting setting each other, and then can increase or reduce the arrangement of sub-level alarm display screen 4 according to the detection order.

In this example, in order to realize the checking of different sub-alarm information, the sub-level alarm terminal 3 further includes a switch portion, where the switch portion in this example is mainly a push switch or a screw switch, and this switch portion is connected to the sub-level alarm display screen 4 of a corresponding level, for example, when the sub-level alarm terminal 3 is two-level, it can be understood as a one-level alarm and a two-level alarm. And the sub-level alarm display screen 4 is correspondingly arranged into two stages, and the sub-level alarm end 3 of one stage is connected with the sub-level alarm display screen 4 of one stage, and the two stages are connected in the same way. And the switch section is also connected to the corresponding sub-level alarm display 4. It should be noted that in this example, the alarm signal is transmitted to the optical word board alarm software system and controls the sub-level alarm terminal 3 to be turned on, when specific alarm information needs to be checked, the alarm information in the optical word board alarm software system is directly displayed on the corresponding sub-level alarm display screen 4 through controlling the switch part, so that the situation that the working efficiency is low due to the fact that the alarm interface is first exited and then the alarm information is checked step by step is avoided, and the possibility of missed check exists. Therefore, it is easy to see that the main alarm text display area 2 mainly prompts main alarm, the sub-level alarm terminal 3 below the bottom prompts specific alarm positions, and the corresponding sub-level alarm display screen 4 controls specific display of sub-level alarm content information through the switch of the sub-level alarm terminal 3. And then, staff can learn the sub-alarm prompt and the alarm content more quickly, and the alarm processing efficiency is improved.

On the basis, in order to enable the optical character plate 1 to be connected with the DCS system 8, the optical character plate alarm system mainly aims to display alarm information in the DCS system 8, and further comprises an output control module which specifically comprises a digital-to-analog conversion module 6 and a communication module 7 connected with the digital-to-analog conversion module 6. In this example, the digital-to-analog conversion module 6 can convert and transmit the alarm information in the optical word card alarm system to the communication module 7, wherein the communication module 7 is mainly connected with the communication end of the DCS system 8, so as to realize the transmission of alarm data, and further realize the display of the optical word card alarm information on the DCS system display module 8.1 of the DCS system 8. And the contrast of the DCS system detection alarm information and the light character plate alarm information can be realized, and the viewing of the light character plate alarm information by different application layers is realized. The alarm information is accurately checked. On the basis of this, the communication module 7 in this example is a wireless communication module in order to further reduce the arrangement of transmission data lines. And further, the DCS system 8 and the optical word card alarm system can be in wireless communication.

In addition, in the use, in order to facilitate the expansion of the display of the warning information of the light character plate, the display of local different areas is realized, and the output control module is provided with a display output interface which can be connected with a display. And furthermore, an external expansion display can be used for displaying alarm information, so that the practicability is improved.
