Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of the utility model protection.

[0017] In order to further understand the contents of the utility model, the utility model is described in detail in combination with the drawings.

[0018] In combination with Figs. 1 to 3As shown, the device for collecting the starting moment of the explosion suppression test, the device is composed of box body 1, light intensity acquisition module, glass window 3 and electric connector 4, the rear end of box body 1 is provided with electric connector 4, the top end of box body 1 is provided with box cover 2, the front end of box body 1 is provided with glass window 3, the inside of box body 1 is provided with light intensity acquisition module, box body 1 is used for protecting the inside light intensity acquisition module, the light intensity acquisition module can convert light intensity into electrical signal, glass window 3 is the detection light window of the light intensity acquisition module, and is used for protecting the light intensity acquisition module, the electric connector 4 can connect the light intensity acquisition module into the explosion suppression test measurement and control system, and the electrical signal converted by the light intensity acquisition module can be transmitted to the explosion suppression test measurement and control system through the electric connector 4.

[0019] Working principle:

[0020] Four M3 screws are used to install the starting moment collection device near the armor-piercing jet point, and the glass window 3 of the starting moment collection device is opposite to the jet point;

[0021] The light intensity acquisition module arranged in the box body 1 generates detection light, the electric connector 4 connects the light intensity acquisition module into the explosion suppression test measurement and control system, and the electrical signal converted by the light intensity acquisition module is transmitted to the explosion suppression test measurement and control system through the electric connector 4, so as to collect the light generated by the armor-piercing jet;

[0022] The starting moment collection device is mainly used for collecting the starting moment of the explosion suppression test of the fire extinguishing and explosion suppression system, according to the definition of the starting moment, when the armor-piercing jet effect is generated in the explosion suppression test, it is the starting moment. When the armor-piercing jet occurs, light will be generated, and the device converts the light brightness into an electrical signal. Different light brightness can be converted into different intensity electrical signals by the device, and the explosion suppression test measurement and control system judges the starting moment through the electrical signal emitted by the starting moment collection device.

[0023] Firstly, the device is different from the way of breaking the printed film by the jet fragment to trigger the starting moment, and the starting moment collection device will not be damaged by the jet fragment, and has the characteristics of repeated use. The starting moment collection device can be repeatedly used, and has good economy. The light brightness generated by the armor-piercing jet is used as the judgment basis, which can collect the starting moment of the explosion suppression test earlier than the printed film, and ensures the accuracy of the starting moment record of the explosion suppression test;

[0024] Secondly, after the printed film is broken by the armor-piercing jet, the collection circuit has a probability of re-adhesion to form a closed loop, so that the starting moment cannot be triggered. The starting moment collection device is non-contact, and the problem does not exist;

[0025] Finally, the starting moment collection device has no direct contact with the armor-piercing jet, which greatly reduces the influence of the armor-piercing jet on the explosion suppression test measurement and control system.
