Definition of Product assessment. Product assessment ' means a process by which a retail food establishment submits food to be tested at a lab approved by Department to determine if the food is time/temperature control for safety or non-time/temperature control for safety. A product assessment shall test intrinsic and extrinsic factors necessary...

Staff metabolism simulation system for ground comprehensive tests of manned spacecraft

The invention discloses a staff metabolism simulation system for ground comprehensive tests of a manned spacecraft. The staff metabolism simulation system mainly comprises an oxygen concentration simulation unit, a carbon dioxide simulation unit, a nitrogen simulation unit and a humidity simulation unit. The staff metabolism simulation system is connected with a sealed cabin through pipelines, and air circulates between the staff metabolism simulation system and the sealed cabin of the manned spacecraft. According to an input simulation staff number and each staff metabolism mode, a control system calculates control targets of the heat production quantity, the humidity production quantity, the oxygen consumption quantity and the carbon dioxide increase quantity in combination with a metabolism based empirical formula, and controls a fan, a valve, a compressor, a molecular sieve, a flow controller, a pump and a heater so as to achieve the control targets through data such as temperatures, pressure, flow and oxygen concentration in an acquisition system according to preset control logic. Compared with staff metabolism simulation systems in prior art, the staff metabolism simulation system has the advantages that no staffs are required for participating in the tests, and capacities of a thermal control system and an environment control system are simultaneously assessed; and compared with tests with the staff, test systems constructed by the staff metabolism simulation system are safer, higher in flexibility, longer in continuous running time and fuller in product assessment, and do not occupy cabin volume.

Simulator for partial discharge modes

InactiveCN104635124AEasy to operateFlexible adjustment of partial discharge occurrence locationTesting dielectric strengthAnalog signalEngineering
The invention provides a simulator for partial discharge modes. The simulator comprises a partial discharge mode generator and a power amplification circuit; the partial discharge mode generator is connected with the input end of the power amplification circuit, and is used for storing various partial discharge modes recorded in advance, and when a selection instruction sent out to any partial discharge mode by a user is acquired, a partial discharge signal in a selected partial discharge mode is converted into a simulation signal for output; the output end of the power amplification circuit is connected with a distribution cable, and is used for acquiring the simulation signal, and after being amplified, the simulation signal is output as an electromagnetic wave, and is propagated along the distribution cable. By implementing the simulator provided by the invention, the partial discharge mode of any position in the distribution cable can be simulated for partial discharge monitoring equipment to be measured and analyzed; the simulator has the characteristics of being safe, portable and easy in operation; difficulties existing in the aspects of influence factor evaluation, product assessment, field application, personnel relevant skill training and the like in application practice are solved.
