6. The inspection device for a coal mine personnel positioning system inspection cycle of claim 1, wherein the electromagnetic shielding box comprises a box body and an upper cover, and the box body is hinged with the upper cover.
7. The inspection device for the inspection period of the coal mine personnel positioning system according to claim 1, wherein the electromagnetic lock comprises a lock body fixedly arranged on the side wall of the electromagnetic shielding box and an iron sheet fixedly arranged on the electromagnetic shielding partition plate.
8. The inspection device for the inspection period of the coal mine personnel positioning system according to claim 1, wherein the inner wall of the electromagnetic shielding box is hinged with one end, far away from the electromagnetic lock, of the electromagnetic shielding partition plate through a hinge, and a handle is arranged at the top of the electromagnetic shielding partition plate.
9. The inspection device for a coal mine personnel positioning system inspection cycle of claim 1, wherein foam is provided at the bottom of the lower space.
10. A method for checking the inspection period of a coal mine personnel positioning system, which adopts the checking device for the inspection period of the coal mine personnel positioning system according to any one of claims 1 to 9, and is characterized by comprising the following steps:
s1, checking preparation, namely opening an upper cover of an electromagnetic shielding box, horizontally placing an electromagnetic shielding partition plate, attracting electromagnetic locks, and respectively placing a plurality of positioning cards in upper spaces of 3 electromagnetic shielding boxes;
s2, starting to check, pressing down a control switch, disconnecting all electromagnetic locks in the 3 electromagnetic shielding boxes, collecting the opening and closing states of the electromagnetic locks by a switching value collecting card, and sending the opening and closing states to an upper computer, wherein the upper computer obtains a time point T' when the states of the electromagnetic locks change; meanwhile, the electromagnetic shielding partition board falls, the positioning cards in the upper space fall into the lower space, and the positioning base station collects the position, the card number and the positioning time of each positioning card and sends the positions, the card numbers and the positioning time to the upper computer; the upper computer performs the following calculation:
if T M T' is less than or equal to Q, and the inspection period is qualified;
if T M -T' > Q, the inspection cycle is not qualified;
wherein T is M The positioning time of the last positioning card received by the upper computer is set; q is a set value of a patrol period, T M -T' is the inspection cycle.
