Embodiment Construction
[0041] In order to further describe the present invention, the specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings and examples.
[0042] like figure 1 The portable gas alarm system in the shown embodiment is an on-line testing, verification and calibration instrument, including a testing system, a verification system, a calibration system, an alarm system and a storage system.
[0043] Among them, the test system includes gas cylinders, flowmeters, gas distribution chambers, and gas testers. The gas cylinders are used to provide calibration gas, the flowmeter controls the amount of gas inflow, the gas distribution chamber centrally mixes the gases, and the gas distribution box and the gas tester The gas to be tested is sent to the gas tester for measurement, and after the test is completed, it enters the gas distribution box through the return gas system. The gas tester consists of a combustibl...

The invention relates to an online testing, check and calibration instrument for a portable gas alarm system. The online testing, check and calibration instrument comprises a testing system, a check system, a calibration system, an alarm system and a storage system. Gas is tested and calibrated through the testing system, the check system and the calibration system. The gas which enters the testing system is tested and compared through a gas tester. When the concentration of the gas exceeds the set standard concentration, an alarm device is triggered and alarms for reminding are given out through female voices, and information is transmitted to the storage system and is filed as historical data for future review. The online testing, check and calibration instrument for the portable gas alarm system are integrated with functions of online calibration, verification, check, debugging and testing of alarms and detectors, and can complete the calibration, the verification, the check and the debugging of the alarms and the detectors under various different situations.
Description
technical field [0001] The invention relates to a portable gas alarm system on-line test, verification and calibration instrument, which belongs to the field of test instruments. Background technique [0002] Driven by the national security policy, the market for flammable and toxic gas alarms and detectors is growing. However, due to the particularity of the key components of the alarm system, the national regulations must be calibrated every year. If the calibration is not in place, it will not only be ineffective. The alarm, on the contrary, paralyzes the user's ideology and understanding, resulting in an increase in gas poisoning accidents. In this way, there is a huge risk in the reliability of the product, and the alarm accuracy, quality and function face serious problems. Therefore, the relevant state departments attach great importance to it. The alarm should be calibrated and checked. [0003] At present, the alarms and detectors on the market are usually calibrate...
